Also, the power supply unit is electrically connected to the light emitting module 35 of the light source unit 17 by the cable 20 . The power supply unit converts, for example, commercial alternating current power into a predetermined lighting power supply and supplies it to the light emitting module 35 to light the light emitting elements.

Next, construction of the lighting device 10 will be described.

A power supply line wired behind the ceiling of the sloped ceiling 13 is drawn downward into the embedding hole 12 and connected to the power supply unit. For example, the power supply unit is placed on the downward slope side of the sloped ceiling 13 .

Here, if, as shown in FIG. It is difficult to install by inserting it into the hole 12.

Therefore, as shown in FIG. 4, the worker puts his or her hand inside the main body 16 from which the decorative frame unit 19 has been removed, and pushes up the light source unit 17 from the opening 30 of the main body 16 . As a result, the light source unit 17 rotates upward around the fulcrum 49 and separates upward from the upper surface portion 23 of the main body 16 . At this time, the fixing screw 53 is in a loosened state, and the light source unit 17 can be rotated.

Then, first, the light source unit 17 is inserted into the embedding hole 12 while returning the pulled out cable 20 to the embedding hole 12 . At this time, one side of the light source unit 17 is inserted into the embedding hole 12 toward the rising slope side of the sloped ceiling 13 .

After the contact portion 56 of the movable member 50 is inserted until it is positioned above the upper surface side of the inclined ceiling 13, as shown in FIG. As it moves, the light source unit 17 is moved toward one side, and the central axis z of the main body 16 is aligned with the central axis of the embedding hole 12 . When the light source unit 17 is released from being pushed up, the contact portion 56 contacts the upper surface of the inclined ceiling 13 and supports one side of the light source unit 17 so that the lens 38 and the like do not contact the inclined ceiling 13 .

As shown in FIG. 6 , the main body 16 is axially inserted into the embedding hole 12 and the flange portion 24 of the main body 16 is pressed against the lower surface of the inclined ceiling 13 . At this time, the reflecting plate 37 and the lens 38 enter the main body 16 through the opening 30, and the light source unit 17 is placed on the upper surface portion 23 (one side upper surface portion 28) of the main body 16, and the light source unit 17 is pushed up together with the main body 16. .

An operator puts his or her hand inside the main body 16 and slides each mounting bracket 26 to the lower side of the main body 16 . Each mounting bracket 26 slides downward of the main body 16 to expand outward and abut on the upper surface of the inclined ceiling 13, sandwiching the inclined ceiling 13 with the flange portion 24 and fixing it.

The fixing screw 53 is tightened from the inside of the main body 16, and the tip of the fixing screw 53 is pressed against the extension part 57 to fix the light source unit 17 to the main body 16 so as not to rotate.

Finally, the mounting springs 67 of the decorative frame unit 19 are hooked to the mounting openings 27 from the inside of the main body 16 while contracting both ends of the mounting springs 67 against the elasticity, and the decorative frame 64 is moved upward toward the main body 16. The decorative frame 64 is pulled up from the main body 16 by the elasticity of the mounting springs 67 at both ends to expand, and the decorative frame 64 abuts against the lower surface of the inclined ceiling 13 . As a result, the decorative frame 64 covers the flange portion 24 of the main body 16 and the reflecting mirror 65 is arranged on the optical axis a of the light source unit 17 .

In the illumination device 10 installed on the inclined ceiling 13 in this manner, the central axis z of the main body 16 is orthogonal to the inclined ceiling 13 and inclined with respect to the direct downward direction, but the optical axis a of the light source unit 17 is directly downward. facing the direction.

Then, by supplying lighting power from the power supply unit to the light emitting module 35, the light emitting module 35 is lit, and the light passes through the lens 38 and is emitted from below the reflecting mirror 65 in the direct downward direction.

Also, the heat generated when the light-emitting module 35 is lit is transferred to the radiator 34 and efficiently radiated into the air from the plurality of fins 41 of the radiator 34 .

In the lighting device 10 of the present embodiment configured as described above, the light source unit 17 is movably supported with respect to the main body 16 by the supporting portion 18, so that the light source unit 17 is positioned on one side from the central axis z of the main body 16. Even if it is displaced and protruded from one side of the main body 16, it is easy to install and can be reliably embedded in the embedding hole 12. - 特許庁

The support portion 18 supports the light source unit 17 so as to be rotatable above the main body 16 about a fulcrum 49 provided at a position deviated from the central axis z of the main body 16. The separated light source unit 17 and main body 16 can be inserted into the embedding hole 12, respectively, and can be securely embedded in the embedding hole 12 with good workability.

Since the contact portion 56 projecting downward is provided on the opposite side of the fulcrum 49 of the light source unit 17, the lens 38 of the light source unit 17 can be moved by contacting the contact portion 56 with the upper surface side of the inclined ceiling 13. etc. can be prevented from contacting the inclined ceiling 13 and protected.

By placing the fixing screw 53 on the other side of the movable member 50 relative to the fulcrum 49, the light source unit 17 can be fixed to the main body 16 so as not to rotate.

The wiring portion 42 to which the cable 20 of the light source unit 17 is wired is provided on the fulcrum 49 side, which is the other side opposite to the side where the amount of rotation of the light source unit 17 is large, that is, the side where the amount of rotation is small. 20 can reduce the influence on the rotation of the light source unit 17 .
