Description

Lighting device

technical field

The invention relates to a vehicle lamp, in particular to a vehicle lamp device capable of emitting light with high efficiency.

Background technique

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.

Therefore, in recent years, more compact light-emitting diodes have been widely used in car lights. For example, my country’s Announcement No. M338177 "Lamp housing and lamp with replaceable optical module" is an example. Please refer to FIG. A module 12 , a plurality of light source bodies 13 , and a combination seat 14 . A guide rail 111 is disposed on the inner wall of the lamp body 11 . Each optical module 12 has a light guide plate 121 , an arc-shaped refraction body 122 formed on a surface of the light guide plate 121 , and a concave cavity 123 formed in the center of the refraction body 122 . The optical modules 12 are positioned in the lamp body 11 by inserting the light guide plates 121 into the guide rail 111 . And these light source bodies 13 are light-emitting diodes, and are combined on a circuit board 15, and this circuit board 15 is arranged in the joint seat 14, makes these light source bodies 13 and the refractive body 122 of these optical modules 12 Corresponding to the recess 123 on the top. A vehicle light is formed by combining the combination seat 14 and the vehicle light main body 11 . In use, the light generated by the light source bodies 13 can be projected into the recesses 123, and then refracted out by the refracting body 122. The light is in the form of astigmatism or concentrating light to meet different usage needs.

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.
