The light guide is a structural member for guiding light emitted by the LED to a front panel or a light emitting position from a PCB (printed Circuit Board), the structural member is generally made of PC (polycarbonate) materials or PMMA (polymethyl methacrylate) materials and has good light guide performance, and the light guide is also called a light guide pipe or a light guide column at home and is widely applied.
Patent No. CN 206178190U discloses a light guide system, which can achieve smaller space occupation, especially smaller space occupation in the longitudinal direction perpendicular to the light guide strip, and conforms to the development direction of the current car light with narrower shape and smaller longitudinal space.
Such a light guide system has the following disadvantages when in use: 1. lamps and lanterns adopt more and more of light guide structure in the existing market, and general shape is the bar, lacks annular light guide structure, can't satisfy different user demands, and the bright homogeneity of annular light guide can't be guaranteed to current structure, for this reason, we propose an annular light guide structure that evenly lights.
SUMMERY OF THE UTILITY MODEL
A primary object of the present invention is to provide an annular light guide structure that illuminates uniformly, which can effectively solve the problems in the background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an annular light guide structure of evenly lightening, includes the PCB board, luminous center is installed to PCB board surface one side, bar light pipe is installed to PCB board top one side, bar pipeline pipe is kept away from PCB board one end and is installed annular light pipe, bar light pipe and the inside of annular light pipe are linked together, the fork pocket has been seted up on annular light pipe surface, optics free-form surface is all installed to fork pocket surface both sides.
Furthermore, the light-emitting center is positioned on one side of the surface of the PCB close to the strip-shaped light guide pipe, and the light-emitting center is arranged in the strip-shaped light guide pipe; the light source is provided by a light emitting center.
Further, the fork groove is positioned at the joint between the surface of the annular light guide pipe and the strip-shaped light guide pipe; the fork grooves are positioned at the connecting part, so that the light can be reflected more comprehensively.
Further, the light-emitting center is a patch LED; and the LED is used as a light source to ensure the illumination brightness.
Compared with the prior art, the utility model discloses following beneficial effect has: PCB board is as electric interconnect's carrier, adopt electronic printing art preparation, play the connection effect, install luminous center on its surface, choose for use paster LED, the circular telegram produces light and then provides the light source during the use, bar light pipe and annular light pipe are installed to luminous center's top, the light that luminous center produced is transmitted to annular light pipe through bar light pipe, fork groove position at the junction is equipped with optics free-form surface, can make light take place the total reflection and propagate left right respectively, make annular light pipe inside can be lighted by the uniform lighting, improve illumination effect and illumination homogeneity, the blank of prior art has been remedied, the variety of customer selection has been improved.
