Problems solved by technology

[0004] However, the light irradiation effect produced by the light source bodies 13 depends on the curvature of the refractive body 122 of the corresponding optical module 12. Therefore, it is necessary to prepare many optical modules 12 with refractive bodies 122 of different curvatures in advance. , the manufacturing cost and the use cost are high, and it will also increase the burden of material preparation

Embodiment Construction

[0021] refer to figure 2 , 3 , is the first preferred embodiment of the vehicle light device of the present invention, including a lamp holder 2, an inner cover 3, a light-concentrating unit 4, a light-emitting unit 5, an inner lamp housing 6, and an outer lamp housing 7.

[0022] The inner surface of the lamp holder 2 is protrudingly provided with a positioning cylinder 21 on the adjacent side, and a positioning groove 22 and a receiving groove 23 are respectively formed on the two opposite sides of the lamp holder 2. The outer surface of the lamp holder 2 is exposed and provided with a A countersink 24 communicating with the inside of the positioning cylinder 21 .

[0023] The inner cover 3 is made of light-transmitting material, which includes a central portion 31, an L-shaped bridging portion 32 and an abutting portion 33 respectively bent and extended from two opposite sides of the central portion 31, and a protruding portion protruding from the central portion. 31 and...

Abstract

An automobile lamp device comprises a lamp seat, an inner cover, a light gathering unit, a light emitting unit, an inner lamp shell and an outer lamp shell. The light gathering unit is arranged between the lamp seat and the inner cover made of a light permeable material, the light emitting unit is arranged on one side of the light gathering unit, the inner lamp shell with an opening corresponding to the light gathering unit is arranged in the lamp seat, and the outer lamp shell made of a light transparent material is combined with the lamp seat. The inner cover is positioned between the lamp seat and the inner lamp shell. Owing to the light gathering unit, light rays emitted by the light emitting unit can be guided to integrally pass through the inner cover and the inner lamp shell to be further irradiated outwards through an opening of the outer lamp shell, so that high efficiency in irradiation can be achieved. In addition, space can be effectively saved by means of opposite arrangement of integral components.

Description

technical field [0001] The invention relates to a vehicle lamp, in particular to a vehicle lamp device capable of emitting light with high efficiency. Background technique [0002] Early car lights used light bulbs as the light source. Since the light bulbs diffuse light in all directions, a reflector needs to be installed behind the light bulb socket to reflect the light so that the light can be directed toward the front of the light bulb. However, the volume of such traditional light bulbs is relatively large, coupled with the arrangement of lamp holders and reflectors, the overall lamp takes up a lot of space, which affects the use and configuration of the interior space of the vehicle. [0003] Therefore, in recent years, more compact light-emitting diodes have been widely used in car lights. For example, my country Announcement No. M338177 "Replaceable optical module lamp housing and lamp" new patent case is an example, please refer to figure 1 , the disclosed car lam...
