    ILLUMINATION DEVICE AND IN PARTICULAR BULB OR TUBE FOR LED LAMP (LEP)
    Object of the invention
    The present invention relates to an LED illumination or lighting device (LED) in particular in the form of a tube or a bulb having a symmetry of rotation about a longitudinal axis LED positioning.
    State of the art
    Light-emitting diode or LED (LED) lamps are electric type lamps that use light emitting diodes (abbreviated LEDs in English or LEDs in English) as a means of illumination or illumination.
    [0003] An LED consists of a semiconductor junction, which emits light due to the flow of a current through the junction.
    Currently, LEDs are able to perfectly replace the conventional tungsten filament incandescent bulb. At equal power, LEDs give a greater light emission than incandescent bulbs, or, which amounts to the same, they use much less current power to emit the same light. The useful life of an LED is longer by several orders of magnitude, that is, from 10 to 100 thousand hours versus 1 to 2 thousand hours for incandescent.
    A light emitting diode lamp, or LED lamp, is a type of electric lamp that uses light emitting diodes (abbreviated LED in French and LED in English).
    [0006] They were mainly used to produce indicator lights because of their supply voltage adapted to the electronics and their long service life (indicator of standby or operation of electrical appliances, signaling, etc.), but with the recent technical progress, they can now also serve to enlighten.
    [0007] A conventional incandescent bulb illuminates starting from a tungsten filament at a high temperature. The light output is particularly bad; about 10% of the energy is converted into visible light, the rest is dissipated as heat. In addition, the rise in temperature of the filament is brutal, with a significant risk of destruction of the filament.
    A lamp made of LED produces light by electroluminescence of a semiconductor, the yield is much more interesting without reaching that of fluorescence phenomena (fluorescent tube, compact fluorescent bulb). The lifetime of the LEDs is much greater than for the latter two mechanisms with a certain advantage, the LEDs do not suffer in any way the alternation ignition / extinetion. However, this is not necessarily the case of the electronics used in the bulb.
    Comparisons of yields, and lifetimes
    The performance of LED bulbs is often at the operating voltage (low voltage) and not at the mains voltage (110-120 OR 220-250 volts).
    Advantages - Unbreakable lamp (polycarbonate).
    - Low power consumption for a correct performance (see comparative table above), but less than incandescence.
    - Lifetime much longer than an incandescent or fluorescent lamp (theoretically 50 000 hours in the proposed case). The end of life being declared by a decline of progressive yield and not by a sudden breakdown.
    - Safety of low voltage operation.
    - Heat proportionally significantly less than incandescence due to better efficiency.
    - Does not produce UV.
    - Can produce a wide variety of colors by simple composition, the manufacture of different light emitting diodes constituting it, or dynamic by changing the voltages supplying the various LEDs.
    - Less placement labor.
    Disadvantages - In 2006, the purchase price of LED lamps is and remains higher (see 5 to 20 times higher than that of a conventional lamp), at equal brightness, but the price should fall quickly given the rapid development of sales; the so-called white LEDs produce this white by mixing a few basic colors and do not have a continuous spectrum like incandescent lamps; - the temperature of the product white often pulls towards the blue (cold white), perceived by the users as giving a "cold" atmosphere to the interiors; however, there are white lamps that are more yellowish (warm white); - the IRC (Color rendering index) is also generally mediocre; - the LEDs do not support high temperatures; the heat dissipation of the LED bulbs is a factor limiting the ramp up of the latter.
    - Blue LEDs as well as white LEDs contain a blue spectrum of high intensity dangerous for the retina if they enter the field of vision, even peripheral. This is of course proportional to their power, and is becoming more and more of a concern as ever more powerful LEDs come on the market. The problem arises for example with LED-based flashes, or their use in the headlights of individual vehicles.
    However, the LEDs present a certain
    number of disadvantages, which is why they have not so far been widely adopted as replacements for incandescent bulbs. Indeed, although LEDs
    require significantly less power for a given light output than incandescent bulbs, it still takes many watts to generate adequate light to illuminate. While the tungsten filament in an incandescent bulb operates at a temperature of about 3000 ° C, the temperature of an LED, which is a semiconductor, can not rise above about 120 ° C. The LED therefore presents a significant thermal problem: if it operates in a vacuum like an incandescent bulb, or even in the air, it will quickly become too hot and fail. This has limited the LED bulbs to a very low power (ie, less than about 3 W), resulting in insufficient lighting to replace incandescent bulbs per unit of LEDs in single use.
    One possible solution to this problem is to use a large metal heat sink, attached to the power LEDs. This heat sink would then extend out of the bulb, removing heat from the LEDs. This solution is undesirable and, in fact, has not been tried, because of the common idea that customers will not use a bulb whose shape is radically different from that of the conventional incandescent bulb; and also because the heat sink will not allow insertion of the bulb into pre-existing fixtures.
    A known method for manufacturing an LED comprises the following steps: an envelope is formed in the form of a plastic bulb, optionally the envelope is filled with a plastic material (preferably thermally conductive), it is installed at least one LED in the plastic before the plastic is baked and the plastic material is cooked.
    According to another embodiment, the device of the invention comprises: a heat-conductive plastic bulb, at least one LED in said heat-conductive plastic bulb and a base (or base) sized to be received in a socket complementary electrical socket capable of performing the power supply of the LED.
    An alternative method of manufacturing an LED comprises the following steps: installing at least one LED in a bulb-shaped mold, filling the mold with a thermally conductive plastic material, baking said plastic material and optionally adding a base ( pellet) to said formed bulb, said method having the feature wherein the plastic is fired at a temperature below that which could damage said LED.
    According to an alternative embodiment of the manufacturing method of an LED, a plastic bulb-shaped envelope is created, the envelope is filled with a thermally conductive material, at least one LED is installed in the material. thermally conductive before gelling the thermally conductive material.

    Brief description of the figures
    The accompanying drawings are included to provide a better understanding of the invention, and are incorporated in the present description and constitute a part thereof. The drawings illustrate embodiments of the invention which, together with the description, serve to explain the principles of the invention.
    [0031] Figure 1 shows a first embodiment of the device according to the present invention.
    [0032] Figure 2 shows a second embodiment of the device according to the present invention.
    Detailed description of the invention
    The present invention is described in detail with the aid of the accompanying figures.
    Whenever possible, the same reference numbers are used in the drawings and in the description to refer to the same parts or similar parts.
    FIG. 1 is a sectional view of the illumination or lighting device of the invention in the form of an LED replacement bulb 10 showing the electroluminescent portion of the LED mounted in a plastics material according to a first embodiment. As shown in FIG. 1, the LED replacement bulb 10 comprises a screw-in base or cap 20, a plastic casing 30, an inner portion 40 containing a transparent or translucent heat-conducting material, which can be any which plastic material 60 is suitable, and at least one LED 50. The envelope 30 (or enclosure) may have any shape, or any of the other conventional or decorative shapes used for the bulbs, including but not limited to Spherical, cylindrical and "flame" shaped envelopes are limited. Alternatively, the envelope 30 may be a tubular (tube-shaped) element, as used in fluorescent bulbs or other designs.
    The base 20 (base) comprises a series of threads 22 and a base pin 24 and is configured to insert (screw) into a standard electrical socket and to establish an electrical contact therewith . The electrical socket is preferably sized to receive an incandescent bulb or other standard bulb as known in the art. However, the base (base) may be modified to fit into any complementary electrical socket that is configured to receive an incandescent bulb, such as a bayonet style base. The base 20 (base) makes electrical contact with the AC power in a socket (socket) through its threads 22 and its base pin 24. Inside the base 20 (base), there is a power supply (not shown) that converts the AC voltage to a form suitable for controlling the ignition of said LED 50.
    As shown in Figure 1, the plastic envelope 30 completely encloses the plastic 60 (not absolutely essential) in the inner portion 40 of the LED replacement bulb 50. The envelope 30 also encloses at least the electroluminescent portion 52 of said at least one LED 50, the connection wires (not shown) exiting through the housing 30 via a sealed connection to the power supply present in the base or base 20.
    The envelope 30 in the form of a bulb is preferably made of a plastic material, a liquid plastic material or a material similar to plastic, such as polycarbonate. However, the envelope 30 may be made of any suitable plastics material.
    One can also consider a glass envelope 30 which has the disadvantage of being breakable. This envelope 30 is preferably transparent or contain a dispersion material 32 dispersed throughout the envelope 30. The dispersion material 32 is preferably configured to disperse the light from the light emitting portion 52 of the LED 50. The dispersion of the A light source from the electroluminescent portion 52 prevents the bulb 10 from appearing as having a point source or a plurality of point sources of light with a plurality of LEDs 50. The envelope 30 may also contain a dispersion material 32 to help change the bluish color of a typical LED to a more yellowish outward-emitting color that more closely resembles light from normal incandescent bulbs.
    In another embodiment, the envelope 30 may comprise a plurality of bubbles (not shown), in which the bubbles disperse light from said at least one LED 50. In yet another embodiment, a dye (not shown) may be added to the envelope 30 or the plasticized material 60 in the envelope 30, the light-shifting dye of the at least one LED 50 from a first color spectrum to a second spectrum of colors.
    In other embodiments, it is conceivable to use colored materials to create color lamps.
    In a particular embodiment, it is conceivable that the envelope 30 or the inner portion 40 is filled (s) with a thermoconductive plastic material 60 such as a liquid plastic material or any other suitable material. This plastics material 60 should be transparent or at least translucent but may also contain a dispersion material 62 to assist in the dispersion of light from the electroluminescent portion 52 of the LED 50.
    The dispersion material prevents the bulb 10 from appearing as having a point source or a plurality of point light sources with a plurality of LEDs 50. In addition, the dispersion material 62 dispersed in the plastics material 60 may be used to change the bluish color of LED portion 52 of LED 50 to a more yellowish color emitted outwardly of envelope 30 and more closely resembling light from standard incandescent bulbs. The plastics material 60 is also preferably electrically insulating.
    The power source is preferably designed to be compatible with pre-existing designs, so that the bulb 10 can directly replace conventional bulbs without requiring modification of the pre-existing fixation. Metal contacts, which will supply the voltage to the power source for said at least one LED 50, are mounted on the bulb 10.
    According to the invention, the LED bulb 10 has a plurality of LEDs 50 in the form (mounted on) one, preferably at least two support (one or preferably at least two columns 70). The bulb 10 comprises a base or base 20, an envelope 30, an inner portion 40 possibly containing a plastics material 60, and a plurality of LEDs 50 with said LED supports 50. The screw base 20 makes an electrical contact. with the AC voltage in a socket via its threads 22 and its base pin 24. Inside the (screw-in) base 20 there is a power supply (not shown) which converts the AC voltage in a form suitable for controlling said at least one LED 50.
    The plurality of LEDs according to the invention are arranged such that they are in one and preferably at least two planes parallel to the longitudinal axis A and therefore perpendicular to the end portion 26 of the base 20 or pellet. Preferably, they are in the form of at least two supports (columns 70) parallel to the longitudinal axis A of the lamp, each of these columns 70 being offset around the longitudinal axis by an angle corresponding to 360 ° / N, (N being the number of columns 70). The number of successive LEDs 50 within the same column 70 is preferably at least 3 and preferably at least 5 or 6.
    These LEDs 50 are arranged to distribute the light source in a suitable configuration. In a preferred embodiment, the plurality of LEDs 50 may be arranged in one configuration. The plurality of LEDs 50 is composed of two parts, the connection wires 54, which connect them to the power supply, and the LED or the LEDs 50 themselves. The connection wires 54 are sufficiently rigid to act as a support 70 for the LEDs 50, and also form the interconnections between the LEDs 50 when there are multiple devices. Envelope 30 also encloses the LED or LEDs 50, connecting wires 54 exiting through envelope 30 through a sealed connection to the power supply. It can be appreciated that in another embodiment, the support may be a different material than the interconnection or connection elements.
    According to another embodiment shown in FIG. 2, which shows a sectional view of an LED bulb 10 showing a plurality of LEDs 50 in a plastics envelope 30, which is preferably thermally conductive, it is also possible to a configuration as shown in Figure 1, but the distal end of the columns 70 is surmounted by a plate 56 parallel to the end portion 26 of the base 20 and therefore perpendicular to said columns 70 and the longitudinal axis A. This plate 56 has at least one LED and preferably at least three or more LEDs arranged on the upper part (with respect to the columns 70) of the plate 56 and / or on the lower part of said plate 56. The interest of presenting such a plate tray 56 is that it avoids making a black hole in the lamp (unlit portion of the surface of the casing 30). A variant of the device of the invention comprises one or more columns 70, parallel to the axis A having tree shapes with several branches (2, 3, 4, 5 or more not shown) having at their ends one or more LEDs 50 .
    The LED replacement bulbs as shown in the figures are shown as replacement bulbs for conventional incandescent bulbs, however, the bulbs and methods as presented herein may be used to any lighting system, including flashlights, headlights for automobiles and / or motorcycles, and / or lanterns, but also fairground lighting, domestic, model, decoration, illumination, TL tubes, industrial or signaling.
    For example, a lamp comprising a bulb or a tube according to the present invention may allow to meet one or more specifications listed below, possibly combined with each other.
    1. LED lamps are of high quality and meet different standards, including RohS.
    2. The LEDs are arranged in "riser column (s)" 7 0 or in (on) a "tray" 56 or in (on) one or more raised trays (s) on said vertical support (second series of columns for example).

    4. "Lamps" are in fixed ignition or in color variation.
    5. The voltage range is between 3V and 260V.
    6. The power for so-called "domestic" use is equivalent to +/- 10 - 15 - 25 - 40 - 60 - 75 - 100 W incandescent and other on request and may be increased up to 150 or 200 W.
    7. The current used is AC or DC.
    8. The bases (bases) are of any type and mainly: B15 - B22 - Ba9s - Bal5s / d - E5 - E10 - E14 - E27 - E40 - bare wire - G5.3 - G13 - GU10 - GX - GY - GZ - Shuttle - R7S - Wedge.
    9. The shapes are: tubular, ball, flame, globe, standard GLS, Pauw Pauw, Beehive.
    10. The "TL" tubes have the usual dimensions.
    11. The dimensions of "bulbs" are up to 250 mm high and 125 mm wide and even see more.
    12. The glass is made of transparent or opaline polycarbonate.
    13. This glassware is of the unbreakable type.
    14. In some cases, bare LED is used for "cabochon" equipment or similar equipment.
    15. The colors are able to cover all the colors of the rainbow as well as the warm white, the cold white and the pure white.
    16. The light rendering temperature is between 2,000 and 10,000 degrees Kelvin for white or in precise wavelength in nanometers for color.

    19. The number of anodes is 2 per column unit.
    20. The service life is between 40,000 hours and 60,000 hours, preferably 50,000 hours.
    21. The number of Lumens depends on the power of the number of LEDs.
    22. The amount of LED is from 1 to 750 and up.
    23. The protection is IP 20 - IP 44 - IP 65.
    24. CE / ISO certificates are obtained for such lamps.
    The advantages offered by lighting from LEDs are multiple: 1. Lifetime 2. Energy saving 3. The fragility of the glass envelope that can be replaced by polycarbonate.
    Already these 3 major advantages over incandescent can mitigate the cost. An operating time is 40 to 60,000 hours with a useful ratio of useful watts divided +/- by 15. The fact that the polycarbonate envelope is not glass, required by the vacuum creates less risk of bodily injury to use by breaking glass.
    The use of the LED is unidirectional with respect to the incandescent lamp where the filament illuminates any azimuth, but for the specific case envisaged and to obtain a greater angle of dispersion of axial brightness, LEDs to plan convex or concave plane or even surmounted or not a magnifying glass whose dome may vary from 20 to 180 ° depending on the specific use is proposed.
    In the context of use where the lamps usually used do not exceed the 10W incandescence and are enclosed in cabochons, we will use sets of LED "bare" in E14 or E10 mainly, although other bushings (sockets) can still be used Bal5s for example.
    In the field of illuminations, incandescent lamps usually used are of the order of 5 / 7W minimum up to 25W maximum; although eventually, there may be 40 or 50 W incandescent color decorative lamps. The illumination lamps are generally equipped with sockets E14, E27 and mainly B22.
    A 3etne area in which LED lamps can be appreciated is in their domestic or private use where the traditional lamps are divided into 15, 25, 40, 60, 75, 100, 150W see.
    The originality of the invention lies in the fact of the arrangement of LEDs on a support which is perpendicular to the base and parallel to the longitudinal axis of the lamp or the tube that contains them.
    The positioning of the support and the placement of the LEDs in column is specific to the present invention. Thus, these LEDs are posed (horizontally) on a support which itself is vertical with respect to the axis of the socket (socket).
    This vertical columns allows to place more LEDs and therefore to place more brightness.
    However, in order to avoid a black hole above the column and to compensate for this missing light effect is added LEDs on a plateau resting on the column.
    By extending this column, we can also create the effect of a luminescent tube (TL).
    On the other hand, in order to recreate a retro-style atmosphere, we can use nothing more than the top of column top platform with LED for example inclined and warm white LED, to create the effect of a filament. An elevated plateau with oblique lamps gives a certain advantage as to the dispersion of the luminosity. These oblique LEDs placed in the middle of the globe represent a certain effect of filaments as long as they are in sufficient number.
    [00 63] The shape of the "lamps" may be tubular, round (small ball), round (standard GLS), Paw Paw, Beehive or other. These lamps can be mounted on different types of sockets, the main ones are listed above.
    By way of example, the financial yield that results from using a lamp according to the present invention compared with an incandescent lamp or even a new type of lamp said economic is included in the comparative table. For the use of a 15W incandescent lamp, an incandescent lamp, an economic lamp and an LED lamp according to the present invention were compared.
    Price calculation in 2009: between incandescent and LED: 1. purchase:
    An incandescent of 15 Watt, lifetime 1,000 hours is at 0.4395 Eur. It takes 50 lamps to reach 50,000 hours from where 0.4395 x 50 = 21.975 Eur. An LED lamp that equates a 15W incandescent (where the LEDs are positioned in floor), and lifespan of 50,000 hours is at 4,0796 Eur. So 5.4 times cheaper than the equivalent price of incandescent.
    2. to consumption:
    An incandescent of 15 Watt for 50,000 hours costs: 0.15 Eur / KW. X 15W. X 50,000h. : 1,000 (KW) * 112,5 Eur
    An LED of 1.2 Watt (to give the same brightness as an incandescent of 15 Watt) during 50.000 hours costs: 0; 15 Eur./KW. X 1.2W. x 50,000 h. : 1000 (KW) = 9.0 Eur. So consumption is 12.5 times cheaper than consumption of incandescence.
    The LED lamp of the invention provides the following advantages: 1. Unbreakable, since the envelope is made of polycarbonate, 2. Lifetime of 50,000 hours (50 times longer than incandescent), 3. It takes 50 times less often replace the bulb, so it's less manpower to pay.
    4. Purchase price: 5.4 times less than the price of incandescence. 5. Consumption: 12.5 times less than the consumption of incandescence.
