Description

Applicable under Article 30, Paragraph 2 of the Patent Law ・Published in March 2022 in the "Comprehensive Catalog of Facility, Outdoor, and Store Lighting 2022" ・March 2022 https://www2.panasonic.biz/jp/ https://esctlg.panasonic.biz/iportal/CatalogSearch.do?method=catalogSearchByAnyCategories&volumeID=PEWJ0001&categoryID=352920000&designID= https://esctlg.panasonic.biz/iportal/cv. do? Published at c=6084230000&pg=1&v=PEWJ0001&d=activeOutt This disclosure relates to lighting fixtures, and more particularly to lighting fixtures with adjustable illumination direction. As a conventional example, the lighting fixture described in Patent Document 1 is exemplified. The lighting fixture described in Patent Document 1 (hereinafter referred to as the conventional example) comprises a fixture body, an arm, a light source substrate, and a power supply substrate. The arm rotatably supports both sides of the fixture body. The light source substrate is arranged within the fixture body perpendicular to the light irradiation direction, and a light-emitting element is mounted on it. The power supply substrate is arranged within the fixture body parallel to the light irradiation direction, and a power supply circuit is provided to supply power to the light-emitting element. The arm has a roughly U-shaped cross-section, comprising a mounting section and a pair of bent arm sections extending from both ends of the mounting section. The tips of both arm sections are attached to the sides of the fixture body in the width direction by adjustment screws. The arm is installed in a predetermined location, and the angle of the fixture body, i.e., the direction of light irradiation, can be adjusted by loosening the adjustment screws. Japanese Patent Publication No. 2018-163786 Figure 1 is a perspective view of a lighting fixture according to an embodiment of this disclosure, viewed from the front.Figure 2 is a perspective view of the same lighting fixture as shown above, seen from the rear.Figure 3 is an exploded perspective view of the same lighting fixture.Figure 4 is a front view of the same lighting fixture.Figure 5 is a right side view of the same lighting fixture.Figure 6 is a rear view of the same lighting fixture.Figure 7 is a plan view of the same lighting fixture.Figure 8 is a cross-sectional view of the main part of the lighting fixture shown above. The lighting fixtures according to the embodiments of this disclosure will be described in detail 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. (1) Overview The lighting fixture A1 according to this embodiment comprises a light source unit 2 (light source section) that emits illumination light, a fixture body 1 that supports the light source unit 2, a frame 3 that has a window 300 through which the illumination light passes and is attached to the fixture body 1, and an arm 4 that rotatably holds the frame 3 (see Figures 1-3). In this embodiment, the lighting fixture A1 has the arm 4 attached to the frame 3, not the fixture body 1. Therefore, since the lighting fixture A1 does not require a mounting point (e.g., screw holes) on the fixture body 1 for attaching the arm 4, the fixture body 1 can be formed from a metal plate. As a result, the lighting fixture A1 according to this embodiment can be made lighter compared to the conventional example where the fixture body is formed from aluminum die-casting. Furthermore, in the lighting fixture A1 according to this embodiment, for example, if the fixture body 1 is formed by processing a sheet of pure aluminum, both weight reduction and improved heat dissipation can be achieved. (2) Details The lighting fixture A1 according to this embodiment (hereinafter referred to as lighting fixture A1) is used, for example, to illuminate outdoor parking lots, grounds, etc. In the following description, unless otherwise specified, the up and down, front and back, and left and right directions indicated by arrows in Figure 1 are defined as the up and down, front and back, and left and right directions of lighting fixture A1. Lighting fixture A1 comprises a fixture body 1, a light source unit 2, a frame 3, an arm 4, a sealing member 5, a power supply unit 6, a power cable 7, a lens unit B1, and the like. (2-1) Fixture body The fixture body 1 has a housing section 10 for housing the power supply unit 6 and a flange section 11 for supporting the light source unit 2 and the lens unit B1 (see Figures 2 and 3). The housing 10 is formed in the shape of a rectangular box with an op
