Between transition region have apparent dark space, when vehicle light shape is long and narrow, need many LED light sources meet lamps and lanterns light it is uniform
Property require, lead to higher cost.The dispersion angle of LED light source is usually unilateral 60 °, therefore is come when using light guide and LED combination
When meeting miscellaneous modeling requirement, LED light source must be blocked, avoided speck and to there is sufficient space to arrange light
It leads, LED light source and LED circuit board if narrow space in lamp chamber can not arrange optical system.
Utility model content
Aiming at the shortcomings in the prior art, the utility model provides a kind of uniform hair of light guide realization by Two-way side entering light
The rear combination lamp of light is combined using LED module with the light guide of Two-way side entering light, and then effectively solving can not in lamps and lanterns narrow space
The luminous uniformity problem of position lamp when arranging optical system, simultaneously bi-directionally the illumination effect uniformity of the light guide of side entering light is more preferable,
Required number of LED light sources is less, greatly reduces lamps and lanterns cost.
To achieve the above object, the utility model adopts the following technical solutions:
A kind of light guide by Two-way side entering light realizes the rear combination lamp of uniformly light-emitting, it includes outer lampshade, decorative circle, interior lamp
Cover, light guide, light guide bracket, LED module and shell, outer lampshade are welded on shell, form a closed cavity；Decorative circle, interior lamp
Cover, light guide, light guide bracket and LED module are arranged in the closed cavity；Interior lampshade, light guide and LED module are installed in light
It leads on bracket, light guide is the light guide of Two-way side entering light；The light that side-emitting LED light source in LED module issues leads in light guide
It crosses total reflection principle and realizes transmission, the light projected from light guide is projected through interior lampshade.
Further, interior lampshade includes interior lampshade patterned surface and interior lampshade card base, and interior lampshade patterned surface will be projected from light guide
Light break up injection, and interior lampshade can be according to its shape of lamps and lanterns space allocation and wall thickness.
Further, light guide includes light guide input face, light guide tooth and light guide patterned surface, and light guide input face extends light,
Light is by polishing on light guide teeth directional, then is projected light by light guide patterned surface, and light guide can according to lamps and lanterns space allocation its
Shape and wall thickness.
Further, side-emitting LED light source and light guide input face distance L are controlled in 2mm, and light emission direction and light guide
Guide line direction is consistent.
Further, light guide is transparent PMMA material；Light guide bracket is opaque material.
The utility model has the advantages that
1. the utility model is combined using LED module with the light guide of Two-way side entering light, the uniformly light-emitting of position lamp, institute are realized
The LED quantity needed is less, and cost is lower.
2. being different from the illumination mode of traditional LED light source, the utility model uses side-emitting LED light source, solves empty
Between insufficient limitation, be effectively combined by it with light guide, light in light guide pass through total reflection principle realize transmission, decorative circle hide
Block cloth sets LED region, avoids speck, realizes uniformly lighting for entire position lamp by the diffusion function of interior lampshade patterned surface.
3. the utility model by the distance controlling of side-emitting LED light source and light guide input face in 2mm, light emission direction and light
It is consistent to guide conducting wire direction, solves the problems, such as not arranging optical system since lamps and lanterns space limits.
