In general, the light distribution angle of the light emitted through the light emitting diode is about 120 °. When the light emitting diode emits light as it is with a wide light distribution angle as described above, part of the emitted light is reflected by the reflector 200 and is emitted to the outside through the opening 100, but the other part of the opening 101 It is directly emitted to the outside through the user can feel the glare (glare).

In order to solve this problem, the light emitting groove 316 may be formed to block light emitted directly from the light emitting diode 312 to the outside of the housing 100. That is, since the protrusion 316b protruding from the bottom surface 316a is formed in the light emitting groove 316, light emitted directly from the light emitting diode 312 to the outside of the housing 100 by the protrusion 316b may be blocked.

The spring 340 may provide an elastic force to the first body 310a and the second body 310b in a direction away from the first body 310a and the second body 310b. That is, the spring 340 is formed between the first body 310a and the second body 310b to push the first body 310a and the second body 310b to each other. Therefore, when the light source unit 300 is inserted into the coupling member 110, the protruding end 313 formed at the upper end of the first body 310a and the second body 310b, the force applied by the spring 340 By this, it can be firmly coupled to the insertion groove 112 of the coupling member (110).

Accordingly, the first body 310a, the second body 310b, and the intermediate body 320 are preferably formed of a material capable of effectively dissipating heat. For example, aluminum (Al), tin (Sn), nickel (Ni), silver (Ag), copper (Cu), titanium (Ti), molybdenum (Mo), tungsten (W), gold (Au), platinum It may be formed of a metal such as (Pt). In addition, irregularities are formed in a portion of the body of the light source unit 300, thereby effectively dissipating heat.

When the light source unit 300 is inserted into the insertion groove 112 of the coupling member 110, the first coupling portion 315a and the second coupling portion 315b form a contact area with the inner surface of the insertion groove 112. Have As such, one surface of the first coupling part 315a and the second coupling part 315b comes into contact with the inner surface of the insertion groove 112 to form a heat conduction route from the light source part 300 to the coupling member 100. Can be. At this time, the heat dissipation effect may increase as the contact area is wider, but the height of the first body 310a and the second body 310b is increased, and as a result, the height of the housing 100 should be increased. Therefore, in order for the lighting device 1 to have an optimal heat dissipation effect, the relationship between the contact area and the height of the housing 100 should be considered.

5. Light source Desorption of the 300 and the coupling member 110

10A and 10B are views illustrating a process of coupling and separating the light source unit 300 and the coupling member 110 according to the embodiment.

1) Combined process

First, as shown in FIG. 10A, the first force F is applied to the first body 310a and the second body 310b of the light source unit 300 rotatably coupled with the lower region as the rotation axis. The angle between the body 310a and the second body 310b is reduced. In this case, the first force F may be opposite to the direction of the elastic force applied by the spring 340. Pressing the lower ends of the first connecting portion 315a and the second connecting portion 315b while applying the first force F, the gap between the first connecting portion 315a and the second connecting portion 315b is narrowed, thereby providing a first body. The angle between the 310a and the second body 310b is reduced.

When the first force F is not applied, the first body 310a and the second body 310b are separated from each other by the elastic force provided from the spring 340, so that the light source unit 300 is coupled to the coupling member. It is difficult to insert into the insertion groove 112 of (110).

Next, as shown in Figure 10b, while applying the first force (F) to the first body (310a) and the second body (310b), the light source portion 300 is inserted into the groove 112 of the coupling member (110). Insert in At this time, when the first force (F) is not applied, the distance between the first body 310a and the second body 310b is further away by the elastic force, the protruding end 313 of the upper end of the light source unit 300 is inserted It may be inserted into the third groove 113 formed on the inner side of the groove 112. Accordingly, the light source unit 300 may be coupled to the coupling member 110.

In addition, when the light source unit 300 is coupled to the coupling member 110, the spring 340 disposed between the first body 310a and the second body 310b is the first body 310a and the second body ( Since the 310b) pushes each other, the protruding end 313 may be more firmly coupled to the third groove 113.

In addition, a uniform pressure is continuously applied to the contact surface between the first connecting portion 315a and the second connecting portion 315b and the insertion groove 112 by the spring 340. Accordingly, heat generated from the light source 300 may be more efficiently transferred through the contact surfaces of the first connecting portion 315a and the second connecting portion 315b and the coupling member 110.

2) Separation Process

When maintenance of the light source unit 300 is required, the light source unit 300 may be separated from the coupling member 110.

When the light source unit 300 is separated from the coupling member 110, a first force F is applied to the first body 310a and the second body 310b so that the first body 310a and the second body 310b are applied. After the small angle formed by the light source 300 is separated from the coupling member 110.
