Description

This disclosure relates to a lighting fixture, and more particularly to a lighting fixture in which multiple light-emitting elements are arranged on a substrate. As a conventional example, the lighting device described in Patent Document 1 is exemplified. The lighting device described in Patent Document 1 has a substantially rectangular substrate having a pattern for electrically connecting multiple LEDs, and a fixed connector mounted at the corner of the substrate and electrically connected to the LEDs via the pattern. Japanese Patent Publication No. 2013-125630 Figure 1 is a perspective view from below of a lighting fixture according to an embodiment of this disclosure.Figure 2 is a perspective view of the light source unit of the same lighting fixture, seen from above.Figure 3 is a perspective view of the light source unit of the same lighting fixture, seen from below.Figure 4 is a perspective view from below of the same light source unit with the cover removed.Figure 5 is a perspective view of the light source unit shown above, seen from below.Figure 6 is a partial front view of the conductive wire connection structure of the light source unit shown above.Figure 7 is a perspective view of the same conductive wire connection structure as shown above, viewed from below. The lighting fixtures according to the embodiments of this disclosure will be described in detail below with reference to the drawings. However, the figures described in the following embodiments are schematic diagrams, and the ratios of the size and thickness of each component do not necessarily reflect the actual dimensional ratios. Furthermore, the configurations described in the following embodiments are merely examples of this disclosure. This disclosure is not limited to the following embodiments, and various modifications are possible depending on the design, etc., as long as the effects of this disclosure can be achieved. (Embodiment) A lighting fixture 1 according to an embodiment of this disclosure will now be described. The lighting fixture 1 is configured to be mounted on a system ceiling. A system ceiling is a suspended ceiling made up of unit ceilings, and has the function of allowing easy installation of equipment (also called fixtures) such as lighting fixtures and air conditioning vents by placing ceiling panels on top of it (see Japanese Industrial Standard JIS A1445 "Test Method for System Ceiling Components"). However, the lighting fixture according to the embodiment of this disclosure is not limited to lighting fixtures for system ceilings, and may be a lighting fixture that can be mounted on a ceiling with a structure other than a system ceiling. (1) Basic configuration of the lighting fixture The lighting fixture 1 mainly consists of a fixture body 2 and two light source units 3, as shown in Figure 1. In the following description, unless otherwise specified, the up and down, left and right, and front and back directions indicated by arrows in Figure 1 are defined as the up and down, left and right, and front and back directions of the lighting fixture 1. (2) Fixture body The fixture body 2, as shown in Figure 1, mainly consists of two housings 20 and two connecting plates 21. The fixture body 2 further has louvers 24. Each of the two containment bodies 20 has a rectangular bottom wall (not shown) and a pair of side walls 202 projecting downward from both the left and right ends along the longitudinal direction of the bottom wall. The two connecting plates 21 are each formed in a rectangular plate shape. One connecting plate 21 constitutes the front wall of each of the two storage units 20. The other connecting plate 21 constitutes the rear wall of each of the two storage units 20. As a result, each storage unit 20 is formed in a box shape with a rectangular opening on the front (bottom) surface facing the bottom wall 201 in the vertical direction. A space 23 is provided between the two housing units 20. The space 23 is enclosed by one side wall 202 of each housing unit 20 and a pair of connecting plates 21, and can accommodate equipment such as air conditioning vents. The louver 24 comprises a plurality of light-shielding plates 240 and a pair of support plates 241 that support these light-shielding plates 240 arranged at equal intervals. The louver 24 is detachably attached to a pair of side walls 202 of the housing 20 so as to overlap the opening of the housing 20. (3) Light source unit (3-1) Basic structure of the light source unit The two light source units 3 have the same structure. As shown in Figures 2 to 5, the light source unit 3 mainly comprises a unit body 30, a light source module 31, and a light-transmitting cover 32. The unit body 30 (an example of a support member) is formed from a metal plate in a long, rectangular trough shape (U-shaped cross-section), as shown in Figure 5. The unit body 30 comprises a long, rectangular base plate 300 and a pair of side plates 301 extending downward from both ends of
