    LIGHTING DEVICE
    This invention relates to a lighting device, comprising a holder in which a gas discharge lamp is provided and reflection means for reflecting the light originating from this lamp.
    More particularly, this invention relates to a lighting device which is provided for use in the lighting of, inter alia, shops, sales areas, showrooms, warehouses and the like, wherein the device is mounted on the ceiling or integrated into the ceiling. This area of application is generally referred to as shop lighting.
    This invention also relates to a shop device itself, comprising a number of racks between which a passage is formed, and a number of lighting devices mounted above this passage, provided with a gas discharge lamp and reflection means for reflecting the light originating from this lamp.
    Many shops, and certainly supermarkets, have sales areas where the products offered for sale are on racks. These racks are usually 1.8 m to 2 m high and are arranged in parallel rows so that a passage of two meters wide is formed between two adjacent rows. It is known to carry out the lighting of such a shop device on the basis of fluorescent lamps mounted on a central line above the passageways.
    In order to achieve lighting that accentuates the products in the racks more, and less illuminates the passage itself, more and more use is made of lighting devices with gas discharge lamps, which are fixed to the ceiling in such a way that the light beam from each device is directed to one of the racking is oriented. In order to uniformly illuminate both racks on either side of a passage, two sets of lighting appliances must be provided per passage.
    As a result, both the installation cost and the energy consumption of such a lighting installation are quite high.
    Moreover, it is often impossible to illuminate the racks on either side of a passage in a uniform manner. After all, the luminaires cannot always be placed in the middle of the passage, for example because the bearing construction of the ceiling does not allow this. Furthermore, the ceiling height, the width of the passage and the height of the racks can also vary, so that the lighting equipment used cannot guarantee optimum and uniform light intensity and light distribution.
    An object of this invention is to provide an effective, energy-efficient and flexible lighting installation, which is suitable for illuminating a passage between shelves in a shop device, and with which the above-mentioned disadvantages can be remedied.
    This object is achieved by providing, according to the present invention, a lighting device comprising a gas discharge lamp and reflection means for reflecting the light emanating from this lamp, wherein the lighting device is provided to produce a Batwing light distribution, and wherein said reflection means comprises at least two include individually orientable reflectors.
    A Batwing light distribution is a light distribution in which the light intensity in a zone below the lighting device is relatively low, while a zone with a relatively high light intensity is obtained on either side of this zone with relatively low light intensity. A symmetrical Batwing light distribution is shown in the attached figure 7.
    The reflectors are preferably so-called asymmetrical reflectors. The position of the focal point of the lamp relative to a reflector differs depending on the reflector position. Because the position of these reflectors is adjustable, the Batwing light distribution achieved with this device can be influenced to a large extent.
    This makes it possible, in all circumstances, to uniformly illuminate the racks on either side of a passage with the same lighting device with one gas discharge lamp. If, for example, the device cannot be placed centrally with respect to the racks, or if the racks to be illuminated are not of the same height, one can achieve uniform and efficient illumination of these racks at a different angle by aligning the respective reflectors. way that accentuates all products equally well.
    The realized lighting can also be changed afterwards and adjusted to very specific requirements or circumstances in the shop interior.
    Because the intended goal is achieved with one and the same device with one lamp, both the installation cost and the energy consumption are significantly reduced, while maintaining the necessary light intensity.
    In a very preferred embodiment of the lighting device according to the present invention, the said gas discharge lamp is arranged in the device such that this lamp is in a substantially vertical position when the lighting device is placed in the position of use.
    This means that the axis of symmetry that runs through the fitting of the gas discharge lamp is in an almost vertical position.
    If one looks at the typical light distribution of a gas discharge lamp, in the vertical planes through the photometric center of the lamp (the so-called C planes), then in all C planes the light intensity for each angle γ (gamma) is between 0 ° and 20 ° and between 160 ° and 180 ° is relatively small, while the light intensity is clearly much higher for an angle γ (gamma) between 20 ° and 160 °.
    This is clearly illustrated by the light distribution curves in Figures 5 and 6 for two different lamp types in the CO / C180 planes (in full line) and the C90 / C270 planes (in dashed line). The measurements were performed according to the C, γ goniophotometry, in accordance with the "Technical report:" The photometry and trigonometry of luminaires "(ISBN 3 900 734 74 7)
    By a vertical arrangement of a gas discharge lamp in a passage between two rows of racks, the desired effect is achieved, exclusively as a result of the characteristic light distribution of the lamp, namely that a Batwing light distribution is achieved with two zones with a relatively high light intensity separated from one another by a zone with a lower light intensity, whereby less light is emitted in the passage, i.e. in the zone under the lamp, than in the direction of the racks on either side of this passage. As a result, means for reducing the light intensity in a zone of the passage situated below the lamp are not necessary. This benefits the simplicity and the cost of the lighting device. This light distribution can be further influenced by means of the separately orientable reflectors.
    In a particularly advantageous embodiment, the lighting device is designed in such a way that the two zones of greater light intensity resulting from the Batwing light distribution can each be positioned separately by directing the said reflectors. As a result, the zones with greater brightness, each separately depending on the need and the circumstances, can be placed further or closer to the vertical axis.
    In another preferred embodiment of the lighting device according to the present invention, the lighting device comprises two reflectors which together form a substantially bowl-shaped or box-shaped reflection space with an open underside, while the gas discharge lamp is arranged mainly in this reflection space, so that each reflector is a part of the gas discharge lamp. reflect light.
    In yet another embodiment, the gas discharge lamp is arranged between the two reflectors, and shielding means are provided to limit or prevent light passage through lateral openings between the reflectors. Preferably, a shielding element is provided on either side of the lamp which has a substantially V-shaped profile at the height of the lamp, the shielding elements with the corner portion of this V-shape facing each other facing the lamp. In another possible embodiment, the V-shaped shielding elements, with the open side of the V facing each other, can be arranged opposite the lamp. As a result, the light which reaches the inner wall of these shielding elements is mainly reflected in the direction of the directional reflectors, so that this light can also be directed towards the racks.
    Shielding means may also be provided to restrict or prevent light passage through openings between the reflectors located at the top. For example, a cover can be provided in or opposite this opening.
    These shielding means preferably have such a shape and dimensions that they cover the openings between the reflectors regardless of the adjusted position of the reflectors. They can, for example, be provided with a reflective surface on the lamp side.
    When the illuminator is mounted above a passage between two rows of racks in the most advantageous position where the reflectors are located on the sides facing the racks on either side of the gas discharge lamp, while said lateral openings between the reflectors on a side facing the passage are provided with the lamp, the first-mentioned screening means prevent too much light from being emitted via the lateral openings in the longitudinal direction of the passage and this passage would be illuminated too much and / or would have a blinding or at least disturbing effect.
    In a particularly preferred embodiment, the reflectors are connected to a common frame, so that each reflector, independently of the other reflector (s), is rotatable relative to a respective axis and can be placed in a number of different positions. The reflectors can be rotatably connected to the frame with simple connecting means.
    Each reflector is preferably designed with a concave top wall facing the lamp and a number of side walls adjoining it.
    The gas discharge lamp is preferably a high-pressure gas discharge lamp, such as, for example, a high-pressure sodium vapor gas discharge lamp or a high-pressure mercury vapor gas discharge lamp.
    In order for the lighting device to be able to meet certain safety requirements, the lamp is preferably provided in a shielded space which is limited by walls made mainly of translucent material. These walls may, for example, consist of glass.
    In a highly preferred embodiment, the lighting device comprises a housing in which the gas discharge lamp and the said reflectors are provided, and is designed as a surface-mounting device.
    In this patent application the term "surface-mounted device" is used, both for a lighting device that is provided to be mounted against a ceiling or wall, and for a lighting device that is provided to be suspended from a ceiling (or other supporting structure) by means of a suspension system. in a position away from that ceiling (or support structure).
    However, the lighting device can also be designed as a built-in device, and be provided with the usual means for integrating and mounting the device in a ceiling.
    One of the main areas of application of the lighting device according to the present invention is shop lighting, more specifically sales areas or warehouses and the like where racks are arranged and where passageways between these racks must be illuminated in a manner that induces accentuating lighting of the products displayed in the racks . An additional object of this invention is therefore a store device in which one or more lighting devices according to the invention are provided.
    More specifically, this invention also relates to a shop device comprising a number of racks between which a passage is formed, and a number of lighting devices mounted above this passage, provided with a gas discharge lamp and reflection means for reflecting the light originating from this lamp, each lighting device being provided around a Batwing produce light distribution, and wherein said reflecting means comprise at least two separately orientable reflectors.
    The advantages and effects described above of the lighting device according to the present invention are fully utilized in such a store device and result in a particularly advantageous store device with a lighting which is more efficient, more energy-efficient and more flexible than is the case in the known store devices.
    Preferably, the lighting devices installed in this shop device are provided with a gas discharge lamp which is in a substantially vertical position. In a most preferred device, the lighting devices are arranged such that a respective reflector is provided on the sides of the gas discharge lamp facing the racks.
    In the following description, a lighting device according to the present invention is described in more detail. This description serves only to further clarify the features and advantages of this invention, and can therefore not be seen as a limitation of the protection claimed in the claims of this patent application for this invention, nor of its scope. In this description reference is made to the accompanying figures by reference numerals. These figures are figure 1, on which a perspective view of a recessed lighting device according to the present invention, viewed from the bottom thereof, is represented, figure 2, on which the lamp and the reflectors of this lighting device are represented in a more schematic perspective view. Figure Fig. 3 shows a bottom view of the parts of the lighting device shown in Fig. 2, Fig. 4 shows the reflectors and the lamp of the lighting device schematically in a side view, in a state in which the reflectors are placed in a mutually different position 5 and 6, representing the light distribution curve, in the C0 / C180 planes and the C90 / C270 planes, of two different gas discharge lamps, respectively a lamp 'PHILIPS CDM-T 70W' and a lamp OSRAM HCI- T 70W 'figure 7, which represents a possible light distribution curve of the lighting device, in the CO / C180 planes and the C90 / C270 planes.
    The lighting device shown in Figures 1 to 4 is designed as a built-in device, and for that purpose comprises a built-in frame (4) which at the bottom carries a rectangular frame (5). The mounting frame (4) is provided to be received in an opening in a ceiling in a position where the frame (5) extends around the opening in the plane of the ceiling, and is provided with fixing means (6) for fixing thereof in the ceiling opening.
    A holder (7) for a gas discharge lamp (1) is fixed downwards with the opening for the lamp fitting, centrally on the mounting frame (4) relative to the frame (5). A high-pressure gas discharge lamp (1) with an elongated shape is placed in this holder (7), so that the symmetry axis (A) of this lamp (1) running through the fitting extends substantially vertically when the lighting device is mounted in a ceiling is. Depending on the desired light intensity and light color, for example, a high-pressure mercury vapor gas discharge lamp (1) can be provided with a power of 35 W, 70 W, 100 W or 150 W. When a high-pressure sodium vapor gas discharge lamp (1) is used, a lamp power can be 50 W or 100 W. A high-pressure xenon gas discharge lamp is also possible.
    The lighting device also comprises two reflectors (2), (3) which are rotatably attached to the mounting frame (4) on either side of the gas discharge lamp (1). These reflectors (2), (3) are each other's mirror image with respect to a vertical plane running through the lamp (1) perpendicular to the long sides of the frame (5).
    Each reflector (2), (3) comprises a bottom edge (8, 9, 10) with three sides (8), (9), (10) which are perpendicular to each other to form a U, and a number on these sides connecting upwards and contiguous reflector walls (11), (12), (13) defining a laterally enclosed reflection space with an open underside. Said edge (8-10) fits on one side of the lamp (1) within said frame (5).
    From the side (8) of the border (8-10) that runs parallel to the adjacent short side of the frame (5), a concave curved top wall (11) runs upwards and ends in the vicinity of the lamp (1) ), while the other two parallel sides (9, 10) of the border (8-10) connect to respective upwardly inclined side walls (12), (13) which connect at the top to the concave top wall (11). The space bounded laterally by these reflector walls (9), (10) is therefore also open on the side facing the lamp (1). The reflector walls (11), (12), (13) are above the frame (5) when the border (8-10) is in the plane of the frame (5). As for the left-hand reflector (2) shown in Figure 1, the reflectors (2), (3) can be rotated downwards.
    Together, both reflectors (2), (3) form a bowl-shaped reflection space with a rectangular open bottom. Because the lamp (1) is located between the reflectors (2), (3), the walls (11, 12, 13) of this reflection space are interrupted at the height of the lamp (1).
    To prevent the light passage between the reflectors (2), (3) in the lateral direction - in a direction perpendicular to the long sides of the frame (5) - there is, at that location, on either side of the lamp (1), shielding element (14), (15) provided. Each shielding element (14), (15) comprises two flat walls connecting at an acute angle and extending downwardly next to the lamp (1). Both shielding elements (14), (15) face the lamp (1) with the corner portion (16) and extend over a sufficient width to cover the openings between the reflectors in every possible position of these reflectors (2) , (3).
    Because of their V-shape at the height of the lamp (1), the shielding elements (14), (15) reflect the light coming from the lamp in the direction of the directional reflectors, so that a considerable part of this light can also end up in racks. This again results in better accentuation of the products in the racks.
    To prevent the light passage between the reflectors (2), (3) in an upward direction, a cover is provided above the lamp (1). The screening means (14), (15) and the cover cap are designed with a reflecting surface on the lamp side, and thus function as fixed reflectors in this device.
    The parallel sides (9), (10) of the collar (8) of each reflector (2), (3) are rotatably connected to the long sides of said frame (5). This connection is made at two opposite locations, so that each reflector (2), (3) is rotatable about an imaginary axis (17) extending perpendicular to the long sides of the frame (5). Each reflector (2), (3) can be placed in a position of choice as a result of this rotation and can be fixed in this position with the aid of conventional (not shown in the figures) mechanical means.
    This lighting device is, for example, integrated into a shop interior in the ceiling centrally above a passage of two meters wide between two rows of racks with different heights of 1.80 m and 2.00 m respectively. The device is mounted so that the long sides of the frame (5) are perpendicular to the longitudinal direction of the passage, and therefore also perpendicular to the direction of the rows of racks arranged on either side. Of course, other arrangements are also possible, such as, for example, an arrangement in which the long sides of the frame (5) run parallel to the longitudinal direction of the passage.
    Each reflector (2), (3) reflects a portion of the light from the lamp (1). Because the position of each reflector is individually adjustable, the light distribution can be determined in such a way that each rack is illuminated in an optimum way. The left reflector reflects the light in the direction of the rack arranged to the left of the passage. The right-hand reflector directs the light onto the rack arranged on the right-hand side. However, the reflectors (1), (2) can also be designed such that the light can be reflected by the left-hand reflector to the rack on the right-hand side and can be directed by the right-hand reflector to the rack arranged to the left. The passage itself is sufficiently illuminated with a lower light intensity so that with this store lighting one can accentuate the range of products placed in the shelves.
    The light distribution of the luminaire, in the C0 / C180 planes (in the vertical plane perpendicular to the racks), is represented in Figure 7 by the full-line curve. The light distribution of the luminaire in the C90 / C270 planes (in the vertical plane parallel to the racks) is represented in Figure 7 by the dashed line curve. This light distribution makes it clear that the light is largely directed in the direction of the racks (in the C0 / C180 planes) and much less in the direction of the passage between these racks (in the C90 / C270 planes).
