Therefore, the upper portion of the intermediate body 330 is formed of a material such as plastic having low thermal conductivity such that heat generated from the lower portion of the first body 310, the second body 320, and the intermediate body 330 is not transferred. Can be.

In addition, heat generated from the primary light emitting diodes 314 and 324 and the auxiliary light emitting diode 334 may be emitted by the body of the light source unit 300 or transferred to the coupling member 110. That is, when the light source unit 300 is inserted into the first insertion groove 112 of the coupling member 110, the light source unit 300 includes the first coupling unit 310a and the second coupling unit 320b. It has a contact area with the inner side of 112. In this way, one surface of the first coupling portion 310a and the second coupling portion 320b is in contact with the inner surface of the first insertion groove 112, so that the heat conduction route from the light source 300 to the coupling member 100 is Can be formed. At this time, the heat dissipation effect may increase as the contact area is wider, but the height of the first body 310 and the second body 320 is increased, and as a result, the height of the housing 100 should be increased. Therefore, in order for the lighting device to have an optimal heat dissipation effect, the relationship between the contact area and the height of the housing 100 should be considered. In addition, irregularities are formed in a portion of the body of the light source unit 300, thereby effectively dissipating heat.

On the other hand, the coupling member 110 of the housing 100 is provided with a first insertion groove 112 in which the inner wall surface extends (that is, extends in the first direction) by the length of the light source unit 300. In addition, the light source unit 300 includes a light source seating part in direct contact with the light source, and first and second coupling parts 310a provided in surface contact with an inner wall surface of the first insertion groove 112 provided in the coupling member 110. 310b). Here, the light source mounting part means a light emitting groove provided with a light emitting diode and a lower portion of the light source unit 300 in which the light emitting groove is formed.

When the lighting device is operated, heat generated from the light source mounting part may be discharged to the coupling member 110 through the first and second coupling parts 310a and 310b. In this case, the inner wall surfaces of the first and second coupling parts 310a and 310b and the first insertion groove 112 make surface contact, so that heat generated from the light source seating part may be transferred to the coupling member 110. have. At this time, the inner wall surface of the first insertion groove 112 extends (that is, extends in the first direction) by the length of the light source unit 300, so that the contact area with the first and second coupling portions 310a and 310b is maximum. Will be achieved. Accordingly, the heat dissipation efficacy of the lighting device can be improved.

On the other hand, since the lower portion of the first body 310 and the second body 320 is manufactured to have an inclined surface facing the reflector 200, the cross section of the light source 300, that is, the first body 310, the second body 320 ), The cross section that the intermediate body 330 is coupled may have a lower width than the upper width. For example, the cross section of the light source unit 300 may have a fan or polygonal shape. However, the present invention is not limited thereto, and the light source unit 300 may have various shapes.

4) Spring (340)

The spring 340 may be disposed at the upper or center portion of the intermediate body 330. For example, the spring 340, as shown in FIG. 4, may be “c” shaped, and may be disposed between the lower 330a and the upper 330b of the intermediate body 330, and the intermediate body. When the first body 310 and the second body 320 are coupled to both sides, the first body 310 and the second body 320 may be disposed to contact inner surfaces of the first body 310 and the second body 320.

The spring 340 may provide an elastic force to the first body 310 and the second body 320 in a direction away from the first body 310 and the second body 320. That is, the spring 340 is disposed between the first body 310 and the second body 320, and serves to push the first body 310 and the second body 320 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 310 and the second body 320 is applied by the spring 340. By this, it can be firmly coupled to the first insertion groove 112 of the coupling member (110).

Polarities of the first and second terminals 123a and 123b are symmetrical with polarities of the seventh and eighth terminals 123g and 123h. For example, when the polarities of the first and second terminals 123a and 123b are '+' and '-', respectively, the polarities of the seventh and eighth terminals 123g and 123h are '-' and '+', respectively. If the polarity of the first and second terminals 123a and 123b are '-' and '+', respectively, the polarities of the seventh and eighth terminals 123g and 123h are respectively '+' and '- Becomes'

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

9 and 10 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. 9, the first body 310 and the second body 320 are applied by applying a first force F to the first body 310 and the second body 320 of the light source unit 300. Make the angle between them smaller. 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 coupling portion 310a and the second coupling portion 320a while applying the first force F, the interval between the first coupling portion 310a and the second coupling portion 320a is narrowed. , The angle formed by the first body 310 and the second body 320 is reduced.

When the first force F is not applied, the first body 310 and the second body 320 are separated from each other by the elastic force provided from the spring 340, so that the light source 300 is coupled to the coupling member. It is difficult to insert into the first insertion groove 112 of (110).

In addition, a uniform pressure is continuously applied to the contact surface between the first coupling portion 310a and the second coupling portion 320a and the first 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 coupling portion 310a and the second coupling portion 320a 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, the first body 310 and the second body 320 are applied by applying a first force F to the first body 310 and the second body 320. After the small angle formed by the light source 300 is separated from the coupling member 110.
