Abstract

The invention discloses a combined optical prism type light guide for an automobile tail light. The combined optical prism type light guide for the automobile tail light is characterized in that optical prism grooves are processed in a light guide plate; combined optical prisms are distributed on a light guide surface through a series of prism grooves according to a certain distribution array manner; incidence of light from an LED light source is achieved through a cylindrical mirror structure on the light guide, and the lights is emitted through the combined optical prisms of the light guide plate and light guide strips connected with the combined optical prisms. The combined optical prisms have superior optical performance, so that the emitted light is uniform and attractive, the light-emitting and refraction areas are greatly increased, and resources are saved; meanwhile, the tail light can easily meet requirements of laws and regulations.

Description

A kind of combining-optics prism formula automobile tail light photoconduction
Technical field
The invention belongs to automobile lamp technical field, be specifically related to a kind of combining-optics prism formula automobile tail light photoconduction.
Background technology
Light source module comprises photoconduction and light-emitting component.Photoconduction is the exiting surface that light in order to be sent by light-emitting component guides to photoconduction, and then makes light source module form uniform area source.Photoconduction is also normal to be occurred with light guide plate form.Generally speaking, light guide plate comprises substrate and is arranged in the multiple optical microstructures on substrate with array way.
Existing taillight position lamp many employings LED and light guide panel combination design.The design of these existing LED and light guide panel, or the light utilization efficiency of light guide panel is not high, needs more or high-power LED light source series connection to realize, adds power consumption; The each several part luminescence of light guide panel is even not, and the light scattered out unsightly.Therefore, address this problem and seem particularly important.
Summary of the invention
For the problems referred to above, the invention provides a kind of combining-optics prism formula automobile tail light photoconduction, it adopts multi-point source, by the combining-optics prism adjustment distribution of light on light guide plate and shooting angle, this kind of combining-optics prism photoconduction has extremely superior optical appearance, be embodied in that light-emitting area is large, exiting surface is even, applied widely, and different shaping demand can be adapted to.
In order to solve the problem, the invention provides a kind of combining-optics prism formula automobile tail light photoconduction, include photoconduction, described photoconduction is made up of photoconduction bar and optical plate, the inner side of described optical plate is provided with photoconduction bar, described optical plate is densely covered with prism groove, described prism groove becomes combining-optics prism by certain way arrangement, the right side of described photoconduction is provided with symmetrical stud installing hole, one side of described stud installing hole is provided with lead, the right-hand member of described photoconduction is provided with cylindrical lens structure, light source enters photoconduction by cylindrical lens structure, by combining-optics prism and light-strip injection lamp housing surface.
Further improvement is: described photoconduction bar is divided into two sections, and described photoconduction bar can require at length and reverse enterprising Row sum-equal matrix according to concrete configuration design.
Further improvement is: when the width of described optical plate reaches certain value X1, X2, just end combining-optics prism, becomes photoconduction bar, and the scope of described X1 is the scope of 5-10mm, X2 is 5-10mm.
The invention has the beneficial effects as follows: on light guide plate, process optical combination prism, LED emits beam, by the cylindrical lens structure on photoconduction, uniform introducing light guide plate, the backward outer transmitting of combining-optics prism adjustment on optical plate, the uniform light, attractive in appearance of injection, adopts the combining-optics prism luminescence of higher luminous efficiency to add luminous refraction area greatly, saves resource.Make car light more easily meet laws and regulations requirement simultaneously.
