    LED LAMP
    The present invention relates to a lamp having a support member for mounting the lamp, at least one LED connected to the support member as well as a cover piston of transparent material, which is connected to the support member and which covers at least one LED.
    Conventional light bulbs with a classic pear-shaped or candle-shaped glass flask are among consumers because of their uniform color neutral andggf. soft light is still very popular, but is being pushed back by the ever stricter energy saving regulations. For example, in the EU at present, lamps with at least 100 W as well as generally those with frosted glass are no longer available, although more recently 75 W bulbs may no longer be delivered.
    The currently propagated as replacement energy-saving lamps, which are usually formed as fluorescent lamps, are, however, not really popular with consumers because of their spectrum, their initial luminescence and the problematic use of mercury among consumers. In addition, they are also controversial if their overall environmental impact is based on an overall balance, i. It also takes into account the energy and expenses involved in manufacturing and recycling.
    In this respect, it has already been considered to use LED lamps as a replacement for the classic light bulb. Such lamps equipped with light-emitting diodes will in future be superior in terms of their energy efficiency even the above-mentioned energy-saving lamps. In addition, they are characterized by a particularly long life, which considered over the lifetime in conjunction with the lower energy consumption, the higher Acquisition costs by saving Electricity costs compensated. In order to give such LED lamps the familiar appearance of the classic, popular light bulbs, it has already been proposed to mount the LEDs on a lamp base and cover them with a cover flask so that, at least when switched off, it appears that it will be a classic one Light bulb used, which is a not insignificant criterion, for example, in classic lights such as Kristalllüs¬tern and the like.
    So far, unsatisfactory is in such LED retrofits that den¬nen as incandescent replacement, the light distribution and visual appearance in the on state. Instead of a uniform, warm glow, the LEDs are often perceived as hard spots of light that affect the desired room atmosphere. In addition, the cooling of the LED lamps has been solved unsatisfactory. Since the heat can not be radiated through the cover piston, but largely formed on the PCB supporting the LEDs, special cooling means are required in the area of the lamp base, which are complicated on the one hand due to the limited space available there and on the other hand often also the shaping in the sense of quite classic incandescent bulb or candle impair insofar as a widened cooling ring is to be provided between the cover piston and the lamp cap.
    From DE 698 21 822 T2 an LED lamp in retrofit design is known, in which the upper part of the flame-shaped cover body is provided with a thickening, whose bulbous curved surface towards the LED is to act as a diffuser. The greater part of the primary radiation thrown by the LED onto said diffuser surface is reflected and radiated transversely through the side walls of the cover piston, while a small portion of the primary radiation enters the thickened head portion of the cover piston via a bead in said diffuser surface and spreads out of the cover piston via it exit. Overall, the reflecting effect of said diffuser surface results in an overall very inhomogeneous appearance, which shines very brightly at the tip of the covering piston, continues to become darker down to the rear side of the reflecting surfaces, then on the outer surface of the cavity in the area of the diffuser surface transversely emitted light rays again becomes clear and finally in the bottom of the Abdeckkolbens back to the LED backward becomes much darker. Because of this very troubled appearance, the viewer recognizes that it is a retrofit lamp. In addition, a uniform distribution of light intensity in the space to be illuminated can not be achieved.
    The present invention has for its object to provide an improved lamp of the type mentioned, which avoids the disadvantages of the prior art and advantageously further develops the latter. In particular, an improved light distribution is to be achieved in an overall system of small size without impairing the energy efficiency of the system.
    According to the invention this object is achieved by a lamp according to claim 1. Preferred embodiments of the invention are the subject of the dependent claims.
    It is therefore proposed to replace the known in classical incandescent hollow piston mitim substantially constant wall thickness by a solid solid body, which encloses or occupies the area in which emits the at least one LED and covers at least one LED. By the use of such a solid body a homogeneously radiating envelope is obtained, wherein the solid body appears more uniform than a hollow body luminous.
    [0010] According to the invention, said covering piston is embodied as a solid solid material body, the light entry surface of which is designed to be significantly smaller and of different shape than its light exit surface. The light entrance surface of the solid material body forms a concave receiving well which encloses the region in which the LED is disposed and has a depth which is less than 1/3 of the height of the cover piston. The covering piston therefore no longer forms a hollow body, the inner and outer surfaces of which, with substantially constant wall thickness, run parallel to one another over larger portions of the covering piston. Rather, the light entrance surface is significantly different from the light exit surface due to the formation as a solid material body. Due to the rather flat design of the said receiving trough, the greatest part of the primary radiation indicated by the LED can be introduced directly into the solid material body without reflections, so that without reflection phenomena and local radiation concentrations a very uniform light distribution over the entire covering piston results. The cover piston is uniformly illuminated and obtains an overall calm, uniform appearance, whereby a uniform light intensity distribution can also be achieved in the room to be illuminated.
    In a further development of the invention can be dispensed with entirely on an additional optics between LED and Abdeckkol¬ben. The equalization of the light propagation is advantageously effected solely by the solid body of the covering piston, which, as it were, forms the only optical system for controlling the propagation of light. Said masking piston may be seated with its light entry surface or the receiving cavity formed thereby above the primary lens of the LED and spaced therefrom. The said primary lens of the LED here forms part of the LED package and may, for example, be a dome-shaped cap sitting over the LED emitter or a silicon layer covering the LED emitter.
    The light entry surface of the Abdeckkolbens can basically be shaped differently, for example, form a flat surface, which is set on the upper edge of the lamp cap and / or on the LEDs. The light entry surface is formed in this case by a Abfla¬chung the outer surface of the Abdeckkolbens.
    In an advantageous embodiment of the invention, however, said light entrance surface of the solid material body can form a cup-shaped receiving trough, which dome-like over the area in which the at least one LED is arranged. Such a dome-shaped light entry surface facilitates the arrangement and recording of the LEDs and the complete coupling of the light emitted into a half-space into the solid material body.
    The aforementioned concave light entry surface may be formed differently in principle in terms of their depth, i. E. the concavity can bulge at different depths into the solid material body. In any case, however, the depth of the concave relative to the total size of the covering piston is limited and advantageously rather flat compared to this. In a further development of the invention, the concave light entry surface may have a depth of less than 25% of the height of the cover plunger, preferably less than 10% of the height of the cover plunger. If a plurality of LEDs are arranged, a plurality of concave receiving troughs may also be provided as light entry surfaces which correspond in their position to the position of the LEDs so that one or possibly several groups of LEDs are accommodated in a concave receiving trough.
    In an advantageous embodiment of the invention, said receiving trough, which can sit rand¬seitig on the support member for the LED and together with this includes the LED, not only limited by the depth, but also herim total of her volume Small compared to the volume of the solid material body. In an advantageous embodiment of the invention, the volume of the receiving trough in which the at least one LED is accommodated is less than 1/4, preferably less than 15%, of the volume of the full material body of the covering piston. This ensures that a large volume is available for the even distribution of the light in the covering piston, which causes a further homogenization of the light exit.
    In an advantageous development of the invention, the light entry surface of the solid material body delimiting the receiving trough is shaped and formed such that at least 80%, preferably more than 90% of the primary radiation emitted by the LED can enter the solid material body without reflections directly. In particular, the inner wall of the covering piston delimiting the receiving trough can be designed to be free of reflective coatings. Alternatively or additionally, the light entry surface may be shaped such that the primary rays emitted by the LED strike the light entry surface at a sufficiently large angle, ie "sufficiently perpendicular", so that the primary beams can enter the solid material body directly.
    The light exit surface of the cover piston can be approximated in any desired manner to the appearance of classic incandescent lamps and in particular form a continuous curved surface of revolution. In a further development of the invention, a pear-, candle- or mushroom-shaped light exit surface may be provided, which is formed by the outer surface of said cover piston.
    In a further development of the invention, said covering piston itself can form the outer surface of the lamp. Optionally, an outer bulb can also be set via said cover piston and at least partially surrounds the cover piston.
    The trained as a solid body Abdeckkolben this can take a much smaller form than the classic bulb and be enveloped by just such a hollow piston in the classical form. In this case, the hollow piston fitted over the solid material covering piston forms the outer surface of the lamp.
    In the sense of a simple embodiment, however, it is preferred to provide only said Ab¬deckkolben and form them in terms of volume substantially corresponding to a conventional incandescent lamp. This allows the entire Abdeckkolbenoberfläche be used.
    In order to achieve a further homogenization and light mixing, the light entry surface and / or the light exit surface of the cover can be provided with light-scattering means, for example in the form of a suitable surface structure, in particular satiniertausgebildet. In an advantageous embodiment of the invention, in particular the Lichtaus¬trittsfläche evenly or, in the case of luminance differences on Vollmaterial-Abdeckkolben, partially different calendered be formed, creating a uniform glowing piston appearance is achieved, the more or less exactly a diffuse
    Standard light bulb corresponds. For example, areas with weaker luminance shaders may be satinized than areas of higher luminance. In particular, this can be completely avoided radiation streaks.
    If the light entry surface is smooth or polished, the light is only scattered on the outer surface. Advantageously, however, the light entry surface can be formed satined, whereby a further homogenization of the light distribution can be achieved.
    In a further development of the invention, the light entry surface and / or the Lichtaustrittsflä¬che the solid material Abdeckkolbens be provided with a colored surface coating, which may optionally be provided on the light entrance surface of a different color than on the light exit surface. By such a color coating, the light color can be changed from the LED used, which can be made in a simple manner despite the use of the same LED modular differently colored lights. Hereinbei is set to a otherwise identical base assembly comprising the lamp cap and the LED, a different colored cover piston.
    Alternatively, or in addition to such a color coating, the solid material Abdeckkolben be dyed per se, gefer¬tigt be, for example, a colored plastic.
    In order to improve the coupling of light into the cover piston, in a development of the invention between the at least one LED and the light entry surface of the cover piston, a light inserter may preferably be provided in the form of a gel filling. In particular, the aforesaid receiving well formed by the concaved light entrance surface may be filled with a light-injecting gel which advantageously covers substantially the entire light entry surface of the cover bulb and advantageously also communicates with the LED. The said light-injecting gel, as it were, connects the at least one LED to the light entry surface of the covering piston. As a result, a better use of the LED luminous flux can be achieved. Alternatively, instead of a gel filling, it is also possible to use a suitable liquid or another medium with light-coupling effect.
    In order to avoid a bulky, unsightly widening of the Lam¬penkorpus in the neck region of the lamp between the lamp base and the curvature of Abdeck¬kolbens with large diameter section, and the appearance of a conventional incandescent closer, is provided in a further development of the invention, a cooling device the heat arising on the printed circuit board of the LED or of the carrier and control structure of the LED is also at least partially dissipated to said masking piston and not only or not, as the case may be, in a conventional manner to the lamp cap or in the region of the lamp cap. Advantageously, to cool the LED carrier and / or LED drive components, the cooling device includes at least one thermal bridge to the capping piston to use the capping piston as a heat exchanger. At least a portion of the resulting heat is thus also dissipated via the cover piston or used to heat the Abdeckkolbens, so that in turn emits heat to the environment.
    In a further development of the invention, the at least one LED can be mounted on a circuit board, which is preferably coupled via at least one heat conductor in the form of several WärmeleitsträngeWärmme conductive to the Abdeckkolben. Such a thermal coupling of the cover piston to the heat sources of the lamp permits a slimmer construction in the region of the lamp neck and / or of the lamp cap, since cooling elements and heat exchangers provided there can be made smaller or can be completely saved.
    The present invention will be explained in more detail with reference to preferred embodiments and associated drawings. In the drawings: Fig. 1 is a schematic representation of a lamp according to an advantageous embodiment

    Embodiment of the invention in which a cone-shaped cover piston is provided.
    The lamp shown in Fig. 1 comprises as a support part a lamp base 2 for mounting the lamp in a conventional lamp socket as used for incandescent lamps. Said lamp cap 2 may comprise positive-locking fastening means, for example in the form of a screw thread 13, in order to be able to fix the lamp 1 in the corresponding lamp socket in a form-fitting manner. In the area of the lamp base 2, connection contacts 14 for supplying power to the lamp 1 can be provided in a manner known per se, which can be brought into contact with corresponding contacts in the lamp socket. Alternatively, however, a differently shaped support part can be provided for such a "classic" lamp socket , which has suitable connection and / or fastening means, in order to assemble the lamp to a corresponding connector of a lamp.
    The lamp base 2 further comprises a heat sink 15, which may have on the outside cooling fins and is advantageously formed of a good heat conductive material. Alternatively or additionally, an active cooling may be provided, which may contain, for example, movable membrane. Said heat sink 15 carries a board 11, on which at least one LED 3 is mounted.
    In order to achieve a good heat transfer, a flat fit between the cooling body 15 and said board 11 is provided, for example, the board 11 can rest with its back surface on a surface of the heat sink 15. Said board 11 may include or carry, in a manner known per se, suitable control and power components for driving the LED.
    On the lamp base 2 and the aforementioned heat sink 15 sits a cover piston 4, which is formed in the embodiment of FIG. 1 overall pear-shaped.
    The said cover piston 4 is embodied here as a solid material body and consists of a transparent material, for example a suitable plastic. Due to the formation as a solid body, said covering piston 4 does not have a hollow body shape with a consistently strong enveloping wall, the outer surface and inner surface of which would essentially run parallel to one another. Said capping piston 4 has only a concave receiving trough 7, which is relatively flat in the illustrated embodiment of FIG. 1 and has a depth T of less than 10% of the height H of the entire capping piston 4.
    The surface of said receiving trough 7 forms the light entry surface 5des Abdeckkolbens 4, the dome-shaped surrounds the area in which the LED 3 is arranged or in which the LED 3 emits light. Generally, the lamp base 2 facing the front side of the Abdeckkolbens 4 whose light entrance surface 5, wherein depending on the formation of said receiving trough 7, only a portion of said end face the actual Lichteintritts¬ 5 forms, in the actual light from the LED 3 forth.
    The light exit surface 6 of the cover piston 4 is formed by its entire remaining surface, i. E. the entire surface of the Abdeckkolbens 4 except for sitting on the lamp base 2 and the heat sink 15 end face surface portion. In the drawn embodiment of FIG. 1, said light exit surface 6 is of pear-shaped design.
    In order to achieve a further homogenization of the light distribution, in an advantageous development of the invention, at least the light exit surface 6 is satin-finished, with the same effect. Also, the light entry surface 5 can be formed satined. As a result, it is possible to achieve a light distribution which essentially corresponds to a diffuse standard incandescent lamp and does not show any radiation breaks. A hollow body would not shine comparably uniformly compared to this and would even require additional optics, which may be dispensed with when using the solid material covering piston 4. In addition, with the help of the solid cover cup 4, the LED light is perfectly mixed, and any LEDs can be used and no particular specifications are to be kept.
    Optionally, the light exit surface 6 and / or the light entry surface 5 may also be provided with a colored surface coating in order to achieve a corresponding coloring of the light. As an alternative or in addition to such a colored surface coating, however, the solid material covering piston 4 per se can also be completely colored, it also being possible for only parts to be colored, for example in the form of marbled color streaks, which provide corresponding color effects. Likewise, the said colored surface coating can be provided only in sections.
    In order to achieve better light coupling into the covering piston 4, the receiving trough 7 can be filled with a gel filling 8. The said gel filling 8 hereby connects the at least one LED 3 to the light entry surface 5 of the covering piston 4. The gel filling 8 advantageously completely fills out the aforementioned receiving trough 7 and connects the LED 3 to the entire surface of the light entry surface 5.
    In order to achieve a further improved cooling and keep the heat sink 15 small, the cooling device 9 can also provide a thermal bridge 10 to the cover piston 4 for active cooling of the circuit board 11 in order to utilize said cover piston 4 as a heat exchanger. Normally, said cover piston 4 would remain cold or have room temperature, since the LED 3 does not give off any heat in the cover piston 4 mentioned. In further development of the invention, however, the circuit board 11 and / or the cooling body 15 supporting the circuit board 11 can be thermally connected to the solar panel by means of a heat conductor 12, which can comprise a multiplicity of heat conducting filaments and / or heat conduction strands, for example in the form of metal wires Covering piston 4 to be coupled.
    In a further development of the invention, the covering piston 4 could in this case be provided on its outer surface with cooling ribs in order to increase the surface and accordingly to improve the cooling performance.
    As shown in Figures 2 and 3, the lamp 1 may also be in the form of a conventional candle light bulb and comprise a candle-shaped cover piston 4, which is advantageously also formed as a solid material body. While FIG. 2 shows an embodiment with only one central LED 3, the embodiment according to FIG. 3 has a plurality of LEDs 3, which can be arranged on the circuit board 11 in the form of a ring or in another, preferably symmetrical distribution, as shown in FIG. 4 shows.
    In contrast to the embodiment according to FIG. 2, a cup-shaped heat sink 15 is provided between the cover piston 4 and the lamp base 2, which has cooling ribs on its outer circumference. The heat sink 15 is on the one hand connected to the circuit board 11 flat, which carries the LED 3, so that the heat from the circuit board 11 is guided over a large area in the Kühl¬ body 15 flat, which may be formed, for example, metallic. On the other hand, said heat sink 15 also flatly adjoins the cover piston 4, so that part of the heat from the heat sink 15 is passed into the cover piston 4. The thermal coupling of the heat sink 15 to the cover piston 4 is realized by a circumferential, flächi¬ges concerns of the heat sink 15 on the cover 4, which may optionally also Wärmeleitpas¬ten and the like may be provided.
    Figures 6 to 8 show further shapes of the Abdeckkolbens 4. As the Figu¬ren 6 and 7 show, in particular, an approximately spherical Abdeckkolben 4 vorgese¬hen be provided, which has a flattening 16, with the cover piston 4 on the lamp base 2bzw. a heat sink 15 sits. According to FIG. 6, the light entry surface 5 on said flat 16 comprises a receiving well 7 in which an LED can be received, while the embodiment according to FIG. 7 comprises a plurality of such receiving wells 7.
    Fig. 8 shows a Fig. 7 similar construction of the Abdeckkolbens 4, which is here, however, formed multi-pear shaped.
    According to FIG. 9, non-round covering pistons 4 having corners and edges can also be used, for example in order to achieve a crystal-like impression. In particular, according to the type of rhinestones or cut gemstones, corresponding shapes can be provided, in which the covering piston has 4 facets.
    10 shows a lamp 1 in which a larger receiving recess 7 is provided in the covering piston 4 made of solid material, in which a board arrangement 11 can be received with a multiplicity of distributed LEDs. As shown in FIG. 10, a plurality of boards 11 oriented towards different sides can be accommodated in the receiving recess with LEDs 3 arranged correspondingly to different sides.
    According to FIG. 11, the solid material covering piston 4 can also be designed to be relatively small, in particular considerably smaller than the conventional bulb bulb, wherein according to FIG. 11 an outer bulb 17 is set over the solid material covering piston 4, which is formed as a hollow body and, for example, substantially the classic shape of a bulb can besitze. Said outer bulb 17 encloses the covering piston 4 and may itself be formed clear or matt or satin.
    Fig. 12 shows a further embodiment in which the cover piston 4 is formed in the shape of a cone having a flat radiating surface 6 which extends substantially perpendicular to the longitudinal axis of the lamp 1 at its end face. The peripheral surfaces of Abdeckkol¬bens 4 may optionally be vapor-deposited to control the light emission, in particular after Arteines spotlights exclusively on the frontal light exit surface 6 dissipate.
    As FIGS. 13 and 14 show, the lamp 1 can also be designed without a conventional lamp base 2. In the case of FIGS. 13 and 14, the carrier part carrying the lamp is formed only by the LED board 11 and / or a component placed thereon, for example a cooling part 15. As shown in Fig. 13, the lamp 1 is connected to a lampshade 18 and mounted to the ceiling via a power cable 19 which is connected to said support member.
    15 shows various embodiments of the solid material covering piston 4 of the lamp 1 shown in FIGS. 13 and 14. According to the partial view (a) of FIG. 15, the covering flask can be deformed at its light exit surface 6 with respect to its surface structure Sections be divided. While a surface piece arranged on the peripheral side has a satined finish, a cap-shaped surface section 6 b arranged on the face side can be clearly formed.
    In this case, instead of a satin finish, another surface structure, for example a knobbed structure or the like, may also be provided.
    Of course, according to the partial view (b) of Fig. 15, the arrangement of frosted and clear surface portions may also be reversed; Here, the front-side cap portion 6b is satin-finished, while the peripheral-side surface portion 6a is clearly formed.
    According to the partial view (c) of FIG. 15, it is also possible to provide surface sections with different degrees of satin finish. For example, the cap-shaped Oberflä¬ chenabschnitt 6b less satined than the peripheral surface portion 6a aus¬gebildet.
    Of course, according to FIG. 15 (d), the subdivision of the differently shaped surface sections may also be different, for example in the longitudinal direction, cf. Fig. 15 (d), wherein here are the Satinierungsvarianten or Klarvarianten shown in the previous partial views possible.
    As FIGS. 16 to 18 show, the design of the lamp 1 can also include a relatively small solid material covering piston 4 of the aforementioned type, which is surrounded by an outer bulb 17 designed as a hollow piston, this embodiment being independent of the design of the carrier part can be provided. As shown in Fig. 16, a lamp base 2 is provided as a support member, while Figs. 17 and 18 show a lamp construction without such a lamp base 2. Here, a comparison of FIGS. 17 and 18 shows that the covering piston 4 can assume different shapes in this variant with outer bulb 17. While Fig. 17 shows a spherical solid cover piston 4 under the outer bulb, as shown in Fig. 18, a cover piston 4 having a spherical portion and a stem portion is provided.
