Vehicle Lamps

Abstract

The invention provides a lamp for a vehicle. A luminous part and lamp units for the vehicle are adopted, wherein the luminous part can enable a light emitting diode (LED) light source to be converted into a linear shape, and compared with the prior art, the light utilization efficiency of each lamp unit for the vehicle is higher. The lamp for the vehicle is provided with the plurality of lamp units for the vehicle. Each lamp unit for the vehicle is provided with a first lens part, a second lens part, a third lens part, a rectangular section and an optical system, wherein each first lens part and each second lens part respectively enable light emitted by the LED light source forming the narrow angle direction and the wide angle direction relative to an optical axis to be converged to light rays parallel to the optical axis, each thirst lens part is arranged in front of each first lens part and each second lens part, each rectangular section integrally extends to one direction and comprises a central area, two first areas arranged on two sides of the central area, two second areas arranged on outer sides of the two first areas, the third lens part comprises a lens part in a panel shape, and a lens combination body is formed by interconnection of each lens body of the plurality of lamp units for the vehicle.

Description

technical field [0001] The present invention relates to a vehicle lamp, and particularly to a vehicle lamp capable of converting an LED light source into a linear light emitting portion (narrow linear light emission). Background technique [0002] Conventionally, in the field of vehicle lamps, an optical system configured to convert an LED light source into a horizontally long linear light emitting unit (narrow linear light emission) has been proposed (for example, refer to Patent Document 1). [0003] Such as Figure 28 (a), Figure 28 As shown in (b), the vehicle lamp 700 described in Patent Document 1 includes: an LED light source 710; area A2, the upper area A1 in the lower area A3); the second reflector 722, which is arranged outside the first reflector 721; the third reflector 723, which is arranged in the lower area A3; and the fourth reflector 724, which It is arranged outside the third reflection mirror 723 . [0004] According to the vehicular lamp 700 described ...

AI Technical Summary

Problems solved by technology

[0006] However, in the vehicular lamp 700 having the above configuration, although the LED light source can be converted into a horizontally long linear light emitting unit, since the direction of the light emitted by the LED light source 710 that forms a narrow angle with respect to the optical axis is mainly used The structure of light, so there is a problem of low light utilization efficiency

[0007] In addition, since the reflective mirrors 721 to 724 are configured to reflect twice by mirrors processed by sputtering or the like, there is also a problem that a loss due to the double reflection occurs (about 30 %), the light utilization efficiency is further reduced
