Description

A kind of highly effective integration LED light source

Technical field

The utility model belongs to the luminescent device technical field, and what be specifically related to is a kind of highly effective integration LED light source.

Background technology

Along with the universal and development of LED semiconductor lighting, the demand of LED integrated optical source is also increasing, improves the heat conduction and heat radiation of LED integrated optical source, reduces packaging cost and becomes the focus that the art professional and technical personnel pays close attention to.existing LED light source is that LED chip is arranged on temperature-uniforming plate, temperature-uniforming plate is to run into cold meeting in a kind of internal volume that utilizes capillarity the molecule of heating power water to be sent to copper coin go into water droplet, the perseveration that so goes round and begins again reaches the function of heat conduction, some chips are gone up on samming version surface admittedly, put with wiring board made of copper again, form chip and stamp gold thread stroke loop in the middle of the copper wiring board, played fluorescent material glue etc. on this space cloth that still has living space after gold thread on copper circuit board, but due to general LED support more complicated, relative cost is high, increased the weight of in process of production the cost of manufacturing enterprise, disadvantaged business enterprise long-run development and volume production fast, and this LED light source in use, need LED light source directly is fixed in directly heat radiation on radiator by the samming version, but owing to having minused the medium of support and heat conductive silica gel between LED chip and radiator, affected the useful life of LED heat radiation and light source.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of simple in structure, the heat conduction and heat radiation performance is good, production cost reduces highly effective integration LED light source is provided.

For achieving the above object, technical solution of the present utility model is: a kind of highly effective integration LED light source, include radiator, LED wafer and wiring board, be fixed with several LED wafers of arrayed on described radiator, described wiring board is provided with the both positive and negative polarity line for conducting LED wafer, the line of LED wafer and wiring board is mounted welding, make the both positive and negative polarity connection in series-parallel of LED wafer.

Preferably, described wiring board is the square net shape.

Preferably, scribble the fluorescent material colloid mixture on described wiring board.

Preferably, described wiring board is one of ceramic circuit-board, aluminum-based circuit board plate, copper base circuit board.

Preferably, the profile of described radiator is square.

By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: LED light source of the present utility model lead have good heat conduction effect, heat dispersion is high, encapsulation is simple, the luminance of light source is high, the advantages such as long service life of light fixture, its manufacture craft is simple, production cost reduces and be easy to the scale volume production, application, highly versatile, practicality is good, is conducive to applying of LED lighting.
