Embodiment Construction

[0060] Embodiments of the present invention will be specifically described with reference to the drawings. In addition, in the drawings used in the following description, the scales are appropriately changed in order to make each member recognizable in size. In addition, the expressions of "front and rear", "left and right", and "up and down" are expressions for convenience of description, and do not limit the posture and direction of the actual use state.

[0061] figure 1 It is an exploded perspective view showing the structure of the light source unit 1 according to one embodiment of the present invention. The light source unit 1 includes a semiconductor light emitting element 10 , a substrate 20 , a heat dissipation member 30 , and an attachment 40 .

[0062] from Figure 2 to Figure 4 The light source unit 1 in a state where these components are assembled with each other is shown. figure 2 (a) shows the appearance seen from above. figure 2 (b) shows the appearance ...

Abstract

The invention provides a light source unit and a vehicle illumination device. When the light source unit is assembled and a semiconductor light-emitting element needs to be replaced, the operation can be easily carried out in a short time. The light source unit (1) can be detachably disposed on the vehicle illumination device. A substrate (20) supports the semiconductor light-emitting element (10). The substrate (20) is provided with conductive contacts (21a, 21b) which are electrically connected with the semiconductor light-emitting element (10). A cooling part (30) equipped with a clamping claw (34) supports the substrate (20). An accessory (40) is provided with conductive terminals (44a, 44b) and a through hole (46). Through the clamping of the clamping claw (34) with the through hole (46), the conductive terminals (44a, 44b) contact with the conductive contacts (21a, 21b).

Description

technical field [0001] The present invention relates to a lighting device mounted on a vehicle. In addition, the present invention relates to a light source unit mounted on the lighting device. Background technique [0002] As such a light source unit, a device using a semiconductor light emitting element as a light source is known. In order to dissipate heat generated by light emission, the substrate supporting the semiconductor light emitting element is fixed to a heat dissipating member. The positioning of the substrate with respect to the heat dissipation member is performed using a member called an attachment. (For example, refer to Patent Document 1) [0003] Patent Document 1: Japanese Patent Laid-Open No. 2012-238501 [0004] In the light source unit described in Patent Document 1, the substrate is fixed to the heat dissipation member by screwing the attachment to the heat dissipation member. Therefore, when assembling the light source unit 1 , it is necessary t...
