Abstract
The utility model aims to disclose an LED highlight plane light source, comprising a highlight refraction substrate, a PCB circuit board and a plurality of lighting emitting diodes; the lighting emitting diodes are arranged on the PCB circuit board; the PCB circuit board is arranged on the highlight refraction substrate; compared with the prior art, the highlight refraction substrate is used to realize effective illumination of the light source through optical refraction so as to increase effective illumination of the LED light source under a condition that power of the LED light source is not increased, therefore, the purpose of the utility model can be realized.
Description
Technical field
The utility model relates to a kind of led light source, particularly a kind of high bright planar light source of LED with high brightness.
Background technology
In lighting technical field, LED (Light Emitting Diode) is progressively substituting existing light source as a kind of emerging light source.Led light source is long except the life-span, power consumption low, the advantage that also have radiationless, empty calory, is easy to reclaim belongs to typical green illumination light source.
The illumination of existing LED lamp is not good, causes application to receive very big restriction, makes the photoelectric conversion rate of light-emitting diodes not high, has caused waste; And the caloric requirement that light emitting diode produces after opto-electronic conversion is through the fin heat radiation, and the problem of fin size also need be inquired into.
Therefore, need the high bright planar light source of a kind of LED especially, solved the problem of above-mentioned existing existence.
The utility model content
The purpose of the utility model is to provide a kind of LED high bright planar light source, to the deficiency of prior art, under the prerequisite that does not improve led light source power, improves effective illumination of led light source.
The technical problem that the utility model solved can adopt following technical scheme to realize:
The high bright planar light source of a kind of LED is characterized in that, comprises a high brightness refraction substrate, a PCB wiring board and some light emitting diodes, and said light emitting diode is arranged on the said PCB wiring board, and said PCB wiring board is arranged on the said high brightness refraction substrate.
In an embodiment of the utility model, be provided with box dam glue around the said light emitting diode.
Further, the width at said box dam glue top is less than the width of said box dam glue bottom, and the cross section of said box dam glue is trapezoidal.
In an embodiment of the utility model, said PCB wiring board is fixed with warming and pressurizing method and the mutual heat seal of said high brightness refraction substrate through semifastening sheet.
In an embodiment of the utility model, said PCB wiring board is connected mutually with said light emitting diode through a supply module.
Further, said supply module also is connected with an adjustment module.
The high bright planar light source of the LED of the utility model; Compared with prior art, adopt high brightness refraction substrate to reach effective illumination of light source, under the prerequisite that does not improve led light source power through light refraction; Improve effective illumination of led light source, realize the purpose of the utility model.
The characteristics of the utility model can consult this case graphic and below better embodiment detailed description and obtain to be well understood to.
