Becomes white light having a low color temperature as a whole.

  A conductor 25 serving as a power supply path to each LED chip is printed on the substrate 22. Although not shown in the figure, in practice, the conductor 25 is patterned so that the LED chips are connected in series, parallel, or series-parallel.

  In addition, a first receptacle 23 and a second receptacle 24 are mounted on the substrate 22. Each LED chip of the first light emitting unit 20 is connected to the first receptacle 23 via a conductor 25. Each LED chip of the second light emitting unit 21 is connected to the second receptacle via the conductor 25. Note that the conductor 25 connecting the first receptacle 23 and the first light emitting unit 20 and the conductor 25 connecting the second receptacle 24 and the second light emitting unit 21 are electrically insulated from each other. By connecting the receptacles 23 and 24 and a lighting device 3 to be described later via a cable (not shown), it is possible to supply lighting power to the light emitting units 20 and 21.

  As shown in FIG. 2, each light emitting module 2 is attached to the main plate 10 of the instrument main body 1 via a heat radiating plate 8. The heat radiating plate 8 is formed of a material having high thermal conductivity (for example, an aluminum plate). Therefore, the heat generated by each light emitting module 2 is radiated to the outside air through the heat radiating plate 8 and the instrument main body 1.

  The lighting device 3 performs lighting control of the light emitting module 2. In the lighting fixture of this embodiment, as shown in FIG.1 (b), the two lighting devices 3 are provided. Moreover, in the lighting fixture of this embodiment, each lighting device 3 performs lighting control of the light emitting module 2 arrange | positioned at each both sides.

  Each lighting device 3 includes a first lighting circuit (not shown) for lighting the first light emitting unit 20, a second lighting circuit (not shown) for lighting the second light emitting unit 21, and a control circuit (not shown). ). Moreover, the lighting device 3 includes a case 30 that houses each lighting circuit and control circuit. The control circuit adjusts the color temperature of the light emitted from each light emitting module 2 by controlling each lighting circuit and adjusting the light output of each light emitting unit 20, 21 to mix colors. In the lighting fixture of this embodiment, the color temperature of light is adjusted in the range of 2700K to 5000K. The control circuit controls each lighting circuit to change the light output of each of the light emitting units 20 and 21 to adjust the light of each light emitting module 2. The control circuit executes the above control based on an external control signal.

  In addition, the lighting device 3 is not limited to the above configuration, and may be any device that controls the lighting of each light emitting module 2.

  The terminal block 4 is mainly for connecting the lighting device 3 to an external power source (not shown). In the lighting fixture of this embodiment, the terminal block 4 includes one power terminal block 40 and two control terminal blocks 41 (see FIG. 1B). The power supply terminal block 40 is provided at the center in the longitudinal direction of the fixture body 1 and connects a power supply line (not shown) connected to an external power supply and a feed line (not shown) from an adjacent lighting fixture. . The power terminal block 40 and each lighting device 3 are connected by internal wiring (not shown). Therefore, it is possible to supply power to the lighting device 3 from the external power source by connecting each lighting device 3 and the external power source via the power terminal block 40.

  The control terminal blocks 41 are provided at both ends in the longitudinal direction of the fixture body 1, respectively, and light control / color control signal lines (not shown) and signal lines from adjacent lighting fixtures (not shown). Connect). Each control terminal block 41 and each lighting device 3 are connected by an internal wiring (not shown). Therefore, by supplying a control signal to each lighting device 3 via any one of the control terminal blocks 41, the control circuit of each lighting device 3 performs light control or color control of each light emitting module 2.

  Each terminal block 4 is covered with a cover 7 as shown in FIG. Each cover 7 is formed in a bag shape having one surface opened from an elastic material such as ethylene-propylene-diene rubber (EPDM). By covering each terminal block 4 with a cover 7, the inside of the instrument body 1 excluding each terminal block 4 can be isolated from the outside of the instrument body 1. Thereby, it can prevent that foreign materials, such as an insect and a dust, penetrate | invade into the inside of the instrument main body 1. FIG.

  As shown in FIGS. 1 (a) and 1 (c), the translucent panel 5 closes the opening at the upper end in FIG. 1 (c) of the instrument body 1 and transmits the light emitted from each light emitting module 2. . The translucent panel 5 is formed in a rectangular plate shape using, for example, acrylic resin or polycarbonate resin. A dot pattern 50 for diffusing light is provided at a portion of the translucent panel 5 facing each light emitting module 2.

Each dot pattern 50 includes four regions 500 to 503 having different dot densities as shown in FIG. The dot density is highest in the first region 500 closest to the light emitting module 2 and decreases as the distance from the second region 501, the third region 502, the fourth region 503, and the light emitting module increases. As described above, by providing each dot pattern 50 on the light transmitting panel 5, the uniformity of the light irradiated to the outside through the light transmitting panel 5 can be made uniform over the longitudinal direction of the light transmitting panel 5. it can.

  In addition, in the lighting fixture of this embodiment, as shown in FIG.1 (c), in order to be able to irradiate light to a wall surface or a ceiling surface efficiently, as shown in FIG.1 (c), the translucent panel 5 is attached to the installation surface (main plate 10 of the instrument main body 1). It is inclined with respect to the surface to which is attached. And in the lighting fixture of this embodiment, the clearance gap S1 is provided between the translucent panel 5 and each lighting device 3. FIG. That is, since the light from the light emitting module 2 adjacent to the lighting device 3 does not easily reach the portion of the translucent panel 5 that faces the lighting device 3, the light is likely to be dark and uneven in light. Therefore, by providing the gap S <b> 1 between the translucent panel 5 and each lighting device 3, light from the light emitting module 2 can be guided to the portion, and uneven light can be hardly generated. At this time, since the upper surface of the case 30 of the lighting device 3 and a part of the second side plate 12 become a reflecting surface, it becomes easy to extract light from the part, and thus it is possible to make the unevenness of light even more difficult to occur. Note that the upper surface of the case 30 can be made a reflective surface by painting with, for example, a white paint.

  Furthermore, in the lighting fixture of this embodiment, the structure of the fixture main body 1 and the translucent panel 5 is devised. That is, as shown in FIG. 5A, among the light emitted from the light emitting modules 2 on both sides sandwiching the lighting device 3, a set of points where the light on the boundary not blocked by the lighting device 3 intersects. Let it be a set P1. And in the lighting fixture of this embodiment, as shown in FIG.5 (b), the fixture main body 1 and the translucent panel 5 are comprised so that this set P1 may not be located in the outer side of the translucent panel 5. FIG. If comprised in this way, the light from the light emitting module 2 can be efficiently guide | induced to the site | part facing the lighting device 3 of the translucent panel 5. FIG.

  As shown in FIG. 1A, the end cap 6 closes both ends of the instrument body 1 in the longitudinal direction. Each end cap 6 is formed of a resin material having translucency such as acrylic resin or polycarbonate resin. As shown in FIG. 6A, each end cap 6 includes a main piece 60, a first side piece 61, a second side piece 62, a third side piece 63, and a fourth side piece 64. Is done. The main piece 60 is formed in a quadrangular shape with the upper side in FIG. And each end cap 6 is comprised in the box which opened one surface as a whole by forming each side piece 61-64 integrally in the four sides of the main piece 60. As shown in FIG.

  As shown in FIG. 6A, the first side piece 61 is formed by cutting out a rectangular first attachment claw 610. Similarly, the second side piece 62 is formed by cutting out two rectangular second mounting claws 620. The tips of the mounting claws 610 and 620 are formed in a bowl shape. Therefore, the end cap 6 can be attached to the instrument body 1 by inserting the tips of the attachment claws 610 and 620 into the attachment holes 114, 121, and 122 of the instrument body 1 and hooking them on the periphery.

  The 3rd side piece 63 is formed so that it may protrude toward the instrument main body 1 rather than the other side pieces 61, 62, 64, as shown to Fig.6 (a). Then, as shown in FIGS. 6B and 6C, the third side piece 63 overlaps the translucent panel 5 with the end cap 6 attached to the instrument body 1. That is, each end cap 6 has a portion that overlaps the translucent panel 5. Thus, a part of each end cap 6 overlaps with the translucent panel 5, so that a gap is hardly generated between the translucent panel 5 and each end cap 6. Therefore, it is possible to prevent foreign matters such as insects and dust from entering the inside of the instrument main body 1 through the gap between the translucent panel 5 and each end cap 6.

  Moreover, in the lighting fixture of this embodiment, as above-mentioned, the end cap 6 is formed with the material which has translucency. For this reason, even when the light emitting module 2 is arranged in the vicinity of both ends in the longitudinal direction of the instrument main body 1, the light emitted from the light emitting module 2 can be irradiated to the outside through the end cap 6. That is, it is possible to avoid the end cap 6 from obstructing the light emitted from the light emitting module 2.

  Here, in the conventional lighting fixture, as shown in FIG. 7A, two types of first light emitting elements 90 and second light emitting elements 91 having different color temperatures are alternately arranged along the longitudinal direction of the fixture body 9. It was arranged continuously. Moreover, in the conventional lighting fixture, as shown in FIG.7 (b), what set each light emitting element 90,91 along the transversal direction of the fixture main body 9 is made into 1 set, and this set is the fixture main body 9 of this set. A plurality of them were continuously arranged along the longitudinal direction. In addition, the 1st light emitting element 90 shall seal the LED chip which light-emits blue light with the sealing material containing a yellow fluorescent substance, and shall be formed in granule. The second light emitting element 91 is formed by sealing an LED chip that emits blue light with a sealing material including an orange phosphor, and is formed in a granular shape.

  However, all of the conventional lighting fixtures have a configuration in which all the light emitting elements 90 and 91 are continuously arranged along the longitudinal direction of the fixture body 9. For this reason, in the conventional lighting fixture, it is necessary to arrange | position the terminal block 4 and the lighting circuit 3 in the back side of the board | substrate (not shown) which mounted each light emitting element 90,91 in the longitudinal direction both ends of the fixture main body 9. FIG. is there.

  When the lighting device 3 and the terminal block 4 are arranged at both ends in the longitudinal direction of the fixture body 9, since the light emitting elements 90 and 91 cannot be placed at both ends of each fixture body 9, for example, a plurality of lighting fixtures are connected. When used, there is a problem that darkening occurs at both ends of each instrument body 9. Moreover, if the fixture main body 9 is designed with a prescribed size, the light emitting area is narrowed by the installation area of the lighting device 3 and the terminal block 4. Furthermore, if a certain light emitting area is to be secured, the longitudinal dimension of the instrument body 9 must be increased by the installation area of the lighting device 3 and the terminal block 4, and the instrument body 9 becomes larger.

  On the other hand, when the lighting device 3 and the terminal block 4 are disposed on the back side of the substrate on which the light emitting elements 90 and 91 are mounted, the above problem can be solved, but the design in consideration of heat dissipation becomes difficult, and the appliance structure is There was a problem of becoming complicated.

  Therefore, as shown in FIG. 3, the lighting fixture of the present embodiment forms one light emitting module 2 from a plurality of light emitting units 20 and 21 having different color temperatures. And in the lighting fixture of this embodiment, as shown in FIG.1 (b), each light emitting module 2 is arrange | positioned at intervals along the longitudinal direction of the fixture main body 1, and between each light emitting module 2, a power supply part is provided. Are configured to be arranged. The “power supply unit” is connected to an external power supply to supply lighting power to each light emitting module 2, and the lighting device 3 and the terminal block 4 correspond to the lighting fixture of this embodiment.

  Therefore, in the lighting fixture of this embodiment, since a power supply part is arrange | positioned between each light emitting module 2, the light emitting module 2 and a power supply part adjoin. For this reason, in the lighting fixture of this embodiment, since the adjacent light emitting module 2 and a power supply part should just be connected, wiring becomes easy. Moreover, in the lighting fixture of this embodiment, since it is not necessary to arrange | position a power supply part in the both ends of the longitudinal direction of the fixture main body 1 and the mounting surface of each light emitting module 2 like the conventional lighting fixture, it is simple. A simple instrument structure can be realized.

  In addition, in the lighting fixture of this embodiment, although the light emitting module 2 and the lighting device 3 are attached to the main plate 10, either one of the light emitting module 2 or the lighting device 3 is attached to the main plate 10, and the other is attached to the first side plate 11 or The structure attached to the 2nd side board 12 may be sufficient. In addition, the lighting fixture of this embodiment may be configured to attach both the light emitting module 2 and the lighting device 3 to the first side plate 11 or the second side plate 12.

  Moreover, in the lighting fixture of this embodiment, although the light emitting module is comprised using the LED chip, you may comprise a light emitting module using other light emitting elements, such as an organic electroluminescent element, for example.
