Description

Car light device

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

Early car lights used light bulbs as the light source. Since the light bulbs radiate light in all directions, a reflector is needed behind the lamp holder to reflect the light so that the light can shine towards the front of the light bulb. However, the volume of such traditional light bulbs is large, and the installation of the lamp holder and the reflection cover causes the entire lamp to occupy a considerable space, which affects the use and configuration of the vehicle's internal space.

Therefore, in recent years, more compact light emitting diodes have been widely used in vehicle lights. For example, the new patent case No. M338177 of China "Light lamp housing and lamp with replaceable optical module" is an example. Please refer to Figure 1. The disclosed lamp housing includes a lamp body 11, most optical The module 12, most of the light source bodies 13, and a combination seat 14. A guide rail 111 is provided on an inner wall surface of the lamp body 11. Each optical module 12 has a light guide plate 121, a refracting body 122 formed on a surface of the light guiding plate 121 and having an arc shape, and a cavity 123 formed at the center of the refracting body 122. The optical modules 12 are positioned in the lamp body 11 by the light guide plates 121 being inserted into the guide rail 111. The light source bodies 13 are light-emitting diodes, and are combined with a light source. On the circuit board 15, the circuit board 15 is disposed in the combining base 14 so that the light source bodies 13 correspond to the recesses 123 on the refractive bodies 122 of the optical modules 12. A vehicle lamp is constituted by combining the coupling seat 14 and the vehicle lamp body 11. In use, the light generated by the light source bodies 13 can be projected on the recesses 123, and then refracted by the refracting body 122, and refracted by the refracting body 122 according to the curvature of the refracting body 122. The light is in the form of astigmatism or condensed light to meet different application needs.

However, the light irradiation effect produced by these light source bodies 13 is It depends on the radian curvature of the refractive body 122 of the corresponding optical module 12. Therefore, it is necessary to prepare many optical modules 12 having the refractive body 122 with different radian curvatures in advance. The manufacturing cost and the use cost are high. burden.

Therefore, an object of the present invention is to provide a lamp device capable of emitting light with high efficiency and effectively saving space.
