Problems solved by technology

[0006] However, the brightness of the light-emitting diodes 412 currently on the market still cannot reach the brightness of ordinary car bulbs, and the projection optical system 4 of the multi-light source system must be used (such as image 3 shown) to form an optical system that complies with relevant regulations; the projection optical system 4 of the multi-source system must be at least two sets of projection optical systems 4 to form a vehicle lamp, and the multiple sets of independent The projected optical system4 will lead to a large overall system of automotive lamps

Abstract

The invention relates to a projection optics system, applied in head lamp device used in car, mainly comprising lighting source group consisted of fixed seat, light emitting diode and reflection mirror; lens fixed at front of lighting source group. As the left-right sides of lens are cut the cross section is formed so as to make the width of lens narrow in the level. When multiple lighting source system is consisted of lighting emitting diode multiple lens are kept close so as to form a multiple lighting source system with tighter and smaller space. Too huge optics system is avoided.

Description

technical field [0001] The invention relates to a projective optical system structure, in particular to a projective optical system structure which uses a light emitting diode as a light source of the projective optical system and is applied to a vehicle lamp. Background technique [0002] Safe, high-efficiency, and streamlined vehicle lamps have always been the research and development goals of vehicle lights. Through the assistance of vehicle lights, drivers can clearly understand the road conditions and reduce the danger and discomfort of glare to other vehicles and pedestrians. [0003] Existing automotive lamps, especially automotive headlights, have mostly used the existing projection optical system 1. The main components of the projection optical system 1 include a light source group 11 and a lens body 12, such as figure 1 As shown, the light source group 11 is composed of a luminous body 111 and a mirror body 112; please refer to figure 2 As shown, the light path p...
