As an improvement, the reflecting surface of the reflector is equipped with several arc convex.

As an improvement, the angle of the emergent shaft of the second reflecting surface and the first cylinder is 45 °.

Brought beneficial effect is the utility model compared with prior art:

The utility model can be achieved 360 ° using the cooperation of light-guiding pillar and reflector and go out light, and perfection replaces conventional bulb；Phase It, not only can letter due to making the light that goes out of LED light source have more directive property using light-guiding pillar progress conduit for existing LED car lamp Change the design of reflector, and can break even and guarantee light-out effect；Furthermore it is possible to different light-guiding pillars is designed according to car light type, So that it is gone out light can satisfy the requirement of regulation；It, being capable of less chip realization since light-guiding pillar can be improved light utilization efficiency The requirement of light out, so more energy efficient.
