Description
Technical field
The utility model relates to a kind of wiring board, concrete a kind of LED light source module wiring board.
Background technology
The existing wiring board for making LED light source module generally includes the radiating base layer of line layer and aluminium matter, and the insulating barrier that the resin between the radiating base layer being arranged on line layer and aluminium matter is made, the pin of LED chip during practical application in light source module is connected with line layer, is finally communicated to power supply.There is serious obstruct problem in the heat radiation of insulating barrier to LED that heat transfer coefficient is lower, the way of prior art reduces thickness of insulating layer to strengthen the heat transfer efficiency between line layer and radiating base layer.But it is not good to cross its insulation effect of thin insulating barrier, wiring board is easily caused to be scrapped because of short circuit.Also there is the luminous too dazzling problem of LED chip in existing LED light source module simultaneously, reduces the effect of LED light source module.
Utility model content
In view of this, the utility model discloses the reliable and LED light source module special circuit plate dispelling the heat good of a kind of insulation effect.
The purpose of this utility model is achieved through the following technical solutions:
A kind of LED light source module wiring board, comprise heat-radiating substrate, wiring board body, described wiring board body comprises the insulating barrier covered above heat-radiating substrate and the line layer covered on the insulating layer, also comprises the multiple LED chip installation components be arranged on line layer; Described LED chip installation component comprises one and penetrates the metal heat-conducting seat that wiring board body is connected with heat-radiating substrate and the dead ring of isolating around metal heat-conducting seat and by metal heat-conducting seat and line layer; Described metal heat-conducting seat top is provided with ring-type reflector; Be provided with the holddown groove of multiple fixed L ED chip bottom described reflector, the bottom of holddown groove is provided with multiple lead channels, and the surface coverage of holddown groove and lead channels has heat insulating lamina, is provided with the wire be communicated with line layer in lead channels.
In the utility model, LED chip is fixed in the holddown groove of metal heat-conducting seat by pin, and is communicated with line layer by described wire.Because the surface coverage of holddown groove and lead channels has heat insulating lamina, LED pin does not directly contact with metal heat-conducting seat and avoids short circuit.Ability gets on the ball and directly connects LED chip and heat-radiating substrate by metal heat-conducting seat, and the heat produced during LED chip work is directly conducted on heat-radiating substrate, effectively can improve radiating efficiency.And the dead ring between heat-radiating substrate and line layer effectively can avoid line layer short circuit, simultaneously to radiating effect without any obstruction.Described heat-radiating substrate is aluminium base, and described metal heat-conducting seat is that aluminum material is made.Described insulating barrier and thin dielectric layer are epoxy resin; Described dead ring is rubber.
Outstanding contact surface is provided with downwards bottom described metal heat-conducting seat; Described heat-radiating substrate is provided with the concave surface coordinated with contact surface; Described contact surface is provided with multiple concentric heat conduction ring.
Contact surface contributes to fixing metal heat-conducting seat, can increase the contact area between metal heat-conducting seat and heat-radiating substrate simultaneously.Described heat conduction ring is conducive to increasing the contact area between metal heat-conducting seat and heat-radiating substrate, improves radiating efficiency.
Described reflector front is provided with the light scattering district of multiple radiate, and light scattering district is provided with the convex grain of astigmatism; The top of described reflector is coated with the light scattering layer of disperse light.
The usual effect of reflector is the light gathering LED chip, enables to be gathered in a directional lighting.But the light of LED chip is too dazzling, assembled the light sensation that strong light damages LED light source module.The existing way that rough interface scattering layer is set in reflector front, but this technology will cause larger light loss, reduce light.Light scattering sites is arranged on reflector front with radial by the utility model, improves the soften of illumination while keeping illumination brightness, the light sensation that final acquisition is outstanding.
The back side of described reflector is provided with the drainage trough of multiple annular, and the cross section of described drainage trough is triangle.Described light scattering layer can select the light diffusing sheet of prior art to realize.
Drainage trough contributes to air at reflector ambient dynamic, improves radiating effect further.
The LED light source module wiring board that the utility model provides has outstanding radiating efficiency and reliable insulating properties, and LED light source module prepared therefrom has the advantages such as long perfomance life, light sensation be outstanding.
