As shown in FIG. 1, the luminaire 1 is a so-called floodlight that can be used to illuminate a flat illuminated surface 100, and can be used, for example, as lighting for a signboard. The lighting fixture 1 is installed so as to irradiate light obliquely from one end 101 side of the irradiated surface 100 toward the irradiation surface. Further, it is desirable that the lighting fixture 1 is mounted in a mounted state in which the protruding width W1 from the irradiated surface 100 to the tip 102 of the fixture does not have a protruding width of, for example, about 0.5 m. The lighting fixture 1 of the present embodiment can be suitably used by setting the protrusion width W1 from the irradiated surface 100 within 1 m and installing it. Further, although not shown, the lighting fixture 1 may be provided on one end 101 of the irradiated surface 100 side by side at predetermined intervals to illuminate a horizontally wide illuminated surface.

FIG. 3 is a plan view of the lighting fixture 1 as viewed from the exit surface side. 4 and 5 are cross-sectional views of the luminaire 1, FIG. 4 is a cross-sectional view taken along the line BB of FIG. 3, and FIG. 5 is a cross-sectional view taken along the line AA of FIG. As shown in FIGS. 2 to 5, the lighting fixture 1 includes a fixture main body 10 and is rotatably attached to a predetermined mounting location by a mounting arm 25 provided so as to sandwich the fixture main body 10.

The instrument body 10 includes a bottomed rectangular box-shaped housing 11 having one surface open, and a light emitting element 12 provided inside the housing 11. The light emitting element 12 is, for example, a high-power LED in which LED chips are densely arranged on an LED substrate to form a planar light emitting portion. A chip-on-board (COB) type LED can be suitably used for the light emitting element 12. The light emitting element 12 of the present embodiment has a rectangular light emitting surface 12A that is horizontally long in the longitudinal direction of the housing 11.

A plurality (two in this embodiment) of light emitting elements 12 are arranged side by side along the longitudinal direction of the housing 11 on the bottom portion 11B of the housing 11. Further, a reflecting mirror 14 for controlling the light distribution of the light emitting element 12 is housed inside the housing 11. The light emitting element 12 is arranged at the bottom 13 of the reflecting mirror 14, and the light emitting surface 12A is arranged so as to face the bottom opening 13A of the reflecting mirror 14. Further, inside the housing 11, a shielding plate 39 is provided between the bottom surface 20 of the housing 11 and the front opening 11A of the housing 11 substantially parallel to the bottom surface 20. The shielding plate 39 is provided so that the internal structure of the housing 11 cannot be seen from the outside via the front cover 40 (light transmitting cover) described later. The shielding plate 39 is provided with a hole 39A having an appropriate size into which the reflecting mirror 14 is inserted. Further, the shielding plate 39 is formed with a locking hole 39B for locking the claw portion 14B provided at the tip of the pair of fixed legs 14A of the reflecting mirror 14.

The housing 11 is made of a material having excellent thermal conductivity, and can be made of, for example, aluminum die-cast. Further, in the housing 11, a light source mounting portion 21 to which the light emitting element 12 is mounted is integrally formed on the bottom surface 20 of the housing 11. A plurality of heat dissipation fins (not shown) that dissipate heat generated from the light emitting element 12 are provided on the back surface of the housing 11. The heat from the light emitting element 12 is transferred to the light source mounting portion 21, and further transferred from the light source mounting portion 21 to the heat radiating fin via the bottom surface 20 to be radiated to the outside. Further, a back guard 50 that surrounds the periphery of a heat radiation fin (not shown) is attached to the back surface 30 of the housing 11.

The back guard 50 can be made of resin and has a function of protecting the structure provided on the back surface of the housing 11 and preventing the finger from coming into contact with the heat radiation fins and the charging portion of the back surface 30 of the housing 11. Have. Further, the back guard 50 is provided with a plurality of slits 51. The slit 51 is formed in a size such that a finger does not enter the inside of the back guard 50 through the slit 51. Further, the heat of the heat radiating fins is radiated to the outside of the back guard 50 through the slit 51. If the heat dissipation is sufficient, it is not necessary to form the heat dissipation fins.

In the housing 11, the front opening 11A is covered with the front cover 40. The front cover 40 is formed of a light-transmitting member such as glass, and is pressed and fixed to the housing 11 from the outside of the housing 11 by a frame-shaped cover holding 41. The cover retainer 41 is made of a resin material and is fixed to the housing 11 by adhesion or screwing. The front opening 11A of the housing 11 is watertightly closed by the front cover 40 and the cover retainer 41.

The reflecting mirror 14 surrounds a plurality of light emitting elements 12 provided side by side along the longitudinal direction of the housing 11, and includes a reflecting surface 15 that reflects light from the plurality of light emitting elements 12 in a desired direction. The reflecting mirror 14 is formed of a resin material such as polycarbonate for weight reduction, and the reflecting surface 15 is formed of a thin film of aluminum vapor-deposited on the inner surface. The reflecting mirror 14 is formed in a substantially rectangular oblong shape in which a reflecting surface 15 is formed in a range extending over the longitudinal opening width of the front opening 11A.

Further, the reflecting mirror 14 is provided between adjacent light emitting elements 12, and includes a partition plate 16 for partitioning the reflecting surface 15 into a first reflecting surface 15A and a second reflecting surface 15B corresponding to each light emitting element 12. .. In this embodiment, since the two light emitting elements 12 are arranged along the longitudinal direction, the reflecting surface 15 is provided with a partition plate 16 for partitioning the reflecting surfaces 15A and 15B. Here, when three or more light emitting elements 12 are arranged on the bottom surface 20 of the housing 11, a plurality of partition plates 16 for partitioning the reflecting surface 15 into a plurality of are provided in association with each light emitting element 12. ..

The partition plate 16 has a function of preventing light from one of the adjacent light emitting elements 12 partitioned by the partition plate 16 from incident on the other reflecting surface 15A or the reflecting surface 15B. Further, the partition plate 16 constitutes a part of the reflecting surfaces 15A and 15B, and the light from one of the light emitting elements 12 is efficiently reflected by the corresponding reflecting surface 15A or the reflecting surface 15B to the irradiated surface 100. It is configured to be irradiated. According to this configuration, the partition plate 16 can prevent the light from the light emitting element 12 from spreading laterally more than necessary and becoming leakage light outside the irradiation range of the irradiated surface, and is efficiently covered. The irradiation surface 100 can be illuminated.

In the reflecting mirror 14, long end surfaces 15D and 15D of the reflecting surface 15 reflect incident light as shown by arrows in FIG. 4, and the side portion SP having a width W of the irradiated surface 100. Therefore, it is configured to illuminate the side SP on the side facing the end faces 15D and 15D.
Further, as shown in FIG. 5, the reflecting mirror 14 is formed on a surface in which both side surfaces 15E and 15F of the short side have the same reflection characteristics. The reflecting mirror 14 has a function of blocking light so that a direct light component having a high luminous intensity in the light of the light emitting element 12 does not face the one end portion 101 side of the irradiated surface 100.

The reflecting mirror 14 is provided with a translucent diffusion cover 18 (diffusion transmission member) that covers a part of the emission opening 17 of the reflection surface 15. The diffusion cover 18 has a function of diffusing the light transmitted through the diffusion cover 18 among the light of the light emitting element 12 emitted from the emission opening 17. The diffusion cover 18 is formed to have a length extending along the length of the reflector 14. The reflecting mirror 14 is provided with edge portions 19 formed on a plane substantially parallel to the light emitting surface of the light emitting element 12 at both ends of the length of the emission opening 17. The edge 19 is formed over the short side of the reflector 14. Both ends of the diffusion cover 18 are adhered to and fixed to the edge 19 of the reflector 14. The diffusion cover 18 may be screwed to the edge portion 19.

The lighting fixture 1 is attached so that the longitudinal direction of the housing 11 is along the side of one end portion 101 of the irradiated surface 100, and the diffusion cover 18 is the reflection of the one closer to the one end portion 101 of the irradiated surface 100. It covers a predetermined range of the exit opening 17 from the end of the mirror 14.
As described above, the luminaire 1 irradiates the irradiated surface 100 with light obliquely from the one end 101 side. The light emitted from the side close to the irradiated surface 100 illuminates the vicinity of the luminaire 1. In particular, the lighting fixture 1 of the present embodiment is attached with a reduced protrusion width. Therefore, in the irradiated surface 100, the irradiation distance cannot be sufficiently secured in the portion close to the luminaire 1, and the light emitted from the exit opening 17 of the reflecting mirror 14 directly directs the one end portion 101 of the irradiated surface 100. When the vicinity is illuminated, there are places where the illuminance becomes extremely high, and uneven illuminance occurs on the entire irradiated surface 100.

The luminaire 1 is attached by adjusting the emission angle so that the direct light component of the light emitting element 12 having a high luminous intensity is directed as far as possible from the luminaire 1 and particularly downward from half the height H of the irradiated surface 100. Has been done. Further, the lighting fixture 1 is provided with a reflecting mirror 14 having a function of blocking light so that the direct light component of the light of the light emitting element 12 does not face the one end 101 side of the irradiated surface 100. That is, the illumination range of the luminaire 1 is mainly set below half the height H of the irradiated surface 100.

The diffusion cover 18 diffuses a part of the direct light of the light emitting element 12 and a part of the light reflected by the short side surface 15F near one end 101 of the reflecting mirror 14 and emitted from the exit opening 17. It has a function. The diffusion cover 18 has a function of diffusing light while having a high light transmittance, and can be made of, for example, polycarbonate. In the present embodiment, the diffusion cover 18 is formed of a polycarbonate plate having a thickness of about 2 mm, and has a high total light transmittance and a diffuse light transmittance. Further, it is desirable to use a diffusion cover having a low parallel light transmittance.

A part of the light going downward from half the height H of the irradiated surface 100 is diffused through the diffusion cover 18 so as to be directed to one end 101 side of the irradiated surface 100 to which the luminaire 1 is attached. It is configured in. As a result, the one end 101 side of the irradiated surface 100 is irradiated with light having a low luminous intensity diffused by the diffusion cover 18.

6 and 7 are diagrams showing the illuminance distribution when the irradiation range of 6 m × 8 m is illuminated by the luminaire 1 of 6 lamps, and FIG. 6 shows the illuminance distribution when the diffusion cover 18 is not attached. , FIG. 7 shows the illuminance distribution when the diffusion cover 18 is attached. In the irradiation range shown in FIGS. 6 and 7, when the diffusion cover 18 is not attached, the maximum illuminance in the irradiation range of 6 m × 8 m is 3826 lpx, whereas when the diffusion cover 18 is attached, the maximum illuminance is 3826 lp. , The maximum illuminance became 2026 lpx. Further, the minimum illuminance / maximum illuminance within the irradiation range of 6 m × 8 m is 0.005 when the diffusion cover 18 is not attached, whereas it is 0.095 when the diffusion cover 18 is attached. rice field. In this way, by providing the translucent diffusion cover 18 that covers a part of the emission opening 17 of the reflector 14, the maximum illuminance within the irradiation range is reduced and the glare (halation) is reduced. Further, since the minimum illuminance / maximum illuminance within the irradiation range of 6 m × 8 m is improved, the entire irradiation range can be illuminated with good uniformity.

According to these configurations, even if the lighting fixture 1 is attached with the width protruding from the irradiated surface 100 suppressed, it is possible to prevent the occurrence of a portion in the irradiated surface 100 where the illuminance becomes extremely high, and the illuminated surface 100 The entire area can be illuminated with uniform light without uneven illuminance. The diffusion cover 18 may be configured to cover, for example, an area of 20 to 50% of the exit opening 17. Needless to say, the illuminance distribution in the irradiated surface 100 can be appropriately adjusted by appropriately changing the size of the diffusion cover 18 and changing the range of the emission opening 17 covered by the diffusion cover 18. do not have.

As described above, according to the present embodiment, the lighting fixture 1 is a lighting fixture 1 that obliquely irradiates the irradiated surface 100 with light from the one end 101 side, and has a front opening 11A on the front surface of the lighting fixture body 10 and a fixture main body. It has a light emitting element 12 arranged on the bottom 13 of the 10 and a reflecting mirror 14 that reflects the light from the light emitting element 12 toward the irradiated surface 100, and emits light toward one end 101 of the irradiated surface 100. A diffusion cover 18 for diffusion was provided.

According to this configuration, the light directed toward the one end 101 side of the irradiated surface 100 provided with the lighting fixture 1 is diffused by the diffusion cover, and the one end 101 side of the irradiated surface 100 is illuminated with the light having a low luminous intensity. be able to. Therefore, even if the lighting fixture 1 is attached with a reduced protrusion width and there is not a sufficient irradiation distance between the lighting fixture 1 and the irradiated surface 100, the illuminated surface 100 is illuminated so that uneven illuminance does not occur. Can be done. Further, even if the lighting fixture 1 is attached with a reduced protrusion width, the irradiated surface 100 can be uniformly illuminated, so that the irradiated surface 100 can be illuminated with a low amount of light because the irradiation distance can be shortened. , Power consumption can be reduced.

Further, according to the present embodiment, the diffusion cover 18 is provided in the emission opening 17 of the reflector 14. According to this configuration, the light emitted from the exit opening 17 of the reflecting mirror 14 can be diffused by the diffusion cover 18, and the light can be easily controlled. Further, the diffusion cover 18 may be formed in an appropriate shape and provided in the emission opening 17, and the irradiated surface 100 can be illuminated with a simple configuration so that uneven illuminance does not occur.

Further, according to the present embodiment, the diffusion cover 18 is integrally provided with the front cover 40 that closes the front opening 11A of the instrument main body 10. According to this configuration, the irradiated surface 100 can be easily illuminated so that uneven illuminance does not occur simply by closing the front opening 11A with the front cover 40 integrally provided with the diffusion cover 18.

Further, according to the present embodiment, the diffusion cover 18 has an area of 20 to 50% of the exit opening 17 of the reflector 14. According to this configuration, the illuminance distribution on the irradiated surface 100 can be adjusted by changing the range of the emission opening 17 covered by the diffusion cover 18.

<Second Embodiment>
Next, a second embodiment of the present invention will be described. In the present embodiment, the same members as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

FIG. 8 is a diagram schematically showing an irradiation state by the lighting fixture 1 of the first embodiment.
As shown in FIG. 8, in the irradiation of the lighting fixture 1, a yellowish yellow region 112 may be generated on the irradiated surface 100, and in the present embodiment, the generation of the yellow region 112 is suppressed. 110 will be described.

FIG. 9 is a front view of the lighting fixture 110 according to the present embodiment. 10A and 10B are views showing the configuration of the diffusion cover 116, FIG. 10A is a top view of the diffusion cover 116, and FIG. 10B is a front view of the diffusion cover 116.
As shown in these figures, the luminaire 110 includes a diffusion cover 116 having a shape different from that of the diffusion cover 18 of the first embodiment, and the diffusion cover edge 116A of the diffusion cover 116 is shown in FIG. 10 (b). As shown in, it is formed in a curved wave shape including a plurality of convex portions 116A1 and concave portions 116A2.

By using the diffusion cover 116 having the wave-shaped diffusion cover edge 116A including the plurality of convex portions 116A1 and the concave portions 116A2, the inventors of the present invention suppress the yellowness of the yellow region 112 in the irradiation of the luminaire 110. We have obtained the knowledge that it can be done.

More specifically, as the light emitting element 12, an LED chip that emits blue light is sealed with a transparent resin such as a silicone resin. In this transparent resin, a phosphor that is excited by the blue light emitted from the LED chip and emits yellow fluorescence is dispersed. The light emitting element 12 obtains white light by mixing blue light and yellow fluorescence, and this white light is radiated from the light emitting surface 12A.
In the luminaire 1 of the first embodiment, as shown in FIG. 3, the linear diffusion cover edge 18A of the diffusion cover 18 is located in the radiation range of the white light, that is, the emission opening 17, and this straight line. It is presumed that the diffused cover edge 18A in the shape is a factor in the generation of the yellow region 112.
Specifically, in the light emitting element 12, since the wavelength of blue light and the wavelength of yellow fluorescence are different, when refraction occurs, it is separated into blue light and yellow fluorescence. It is considered that the yellow region 112 is generated by the separation due to the refraction occurring when the white light passes through the diffusion cover edge 18A.
On the other hand, in the diffusion cover 116 of the present embodiment, the wave-shaped convex portion 116A1 and the concave portion 116A2 of the diffusion cover edge portion 116A disperse the light emitted from the diffusion cover edge portion 116A toward the yellow region 112. It is considered that the yellow fluorescence is diffused and the yellow region 112 becomes inconspicuous.

As described above, according to the present embodiment, since the diffusion cover edge portion 116A of the diffusion cover 116 includes the plurality of convex portions 116A1 and the concave portions 116A2, the yellow region 112 can be made inconspicuous.

FIG. 11 is a diagram showing a modified example of the diffusion cover 116 according to the present embodiment.
The diffusion cover 116A of the diffusion cover 116 includes at least one of the convex portion 116A1 and the concave portion 116A2, and any shape of the diffusion cover 116 can be used as long as it has a shape that disperses the light emitted from the diffusion cover edge 116A. You may use it.
For example, as shown in FIGS. 11 (a) and 11 (b), diffusion covers 117 and 118 having a shape in which the diffusion cover edge 116A includes at least one of the convex portion 116A1 and the concave portion 116A2 are used. May be good.
Further, for example, the convex portion 116A1 and the concave portion 116A2 of the diffusion cover edge portion 116A are not curved, and a rectangular diffusion cover 119 may be used as shown in FIG. 11 (c).

The first embodiment and the second embodiment show only one aspect of the present invention, and can be arbitrarily modified and applied without departing from the spirit of the present invention.
For example, in each of the above-described embodiments, the lighting fixtures 1 and 110 have a rectangular shape including a box-shaped housing 11, but the shape of the lighting fixture is not limited to a rectangular shape, and may be, for example, a circular shape or a polygonal shape. It may be formed. Further, in each of the above-described embodiments, the light emitting element 12 is configured to be a COB type LED having a rectangular horizontally long light emitting surface 12A, but the present invention is not limited to this, and a plurality of SMD type LEDs and LED elements are arranged side by side. It may have been done. Further, in each embodiment, the diffusion covers 18, 116, 117, 118, and 119 are plate-shaped members provided in the emission opening 17 of the reflector 14. However, the present invention is not limited to this, and the diffusion covers 18, 116, 117, 118, and 119 may be configured to be integrally formed with the front cover 40 in a part of the front cover 40.
