Description

Multi-chip high power LED light fixture and radiator structure

Technical field

The utility model relates to a kind of radiator structure of multicore sheet packaged high-power LED light fixture, is used for the road traffic lighting field.

Background technology

The prior art relevant with the application, its fitting structure normally with a plurality of led chips by heat sink welding of aluminum substrate, and aluminium base is connected one with the lamp radiator housing reaches the heat radiation purpose, two electrodes of led chip are realized interconnecting by a plurality of pellet electrodes that are provided with on the welding substrate.This light fixture is owing to be subjected to the restriction of radiating condition, volume is generally bigger, the integrated super-high-power LED of multicore sheet that adopts is because its caloric value is many at present, heat sink, substrate and this traditional packaged type thermal resistance of housing radiator are big, make the needs that traditional radiator behind the light fixture can not satisfy heat radiation at all, cause the integrated super-high-power LED unstable properties of multicore sheet, and then can not extensive use.

The utility model content

The purpose of this utility model is to provide a kind of multi-chip high power LED light fixture and radiator structure, effectively solves the heat dissipation problem of the integrated high-power LED lamp of multicore sheet.

For this purpose, the utility model provides a kind of multi-chip high power LED light fixture, it comprises a substrate, substrate is offered the concave surface of integrated a plurality of led chips on basal plane, at the integrated a plurality of led chips of concave bottom, scribble fluorescent glue on a plurality of chips after integrated, be stamped optical lens on the substrate, extend many heat pipes respectively in the substrate both sides, a plurality of fin are installed on the heat pipe.

The utility model provides a kind of radiator structure of multi-chip high power LED light fixture simultaneously, it comprises a substrate, substrate is offered the concave surface of integrated a plurality of led chips on basal plane, extend many heat pipes respectively in the substrate both sides, and a plurality of fin are installed on the heat pipe.

The multi-chip high power LED light fixture that the utility model provides, a plurality of chips are integrated into the substrate concave surface, the radiator structure that this is novel, in the substrate both sides a plurality of heat pipes are set, a plurality of fin are set on heat pipe, have saved being connected between heat sink, heat sink and the aluminium base, aluminium base and aluminium base and multiple thermal resistances such as being connected of radiator, thereby, effectively improve heat-sinking capability, reach better radiating effect; Heat-conducting effect is very good, effectively solves the integrated and heat dissipation problem of multi-chip high power LED light fixture.

Below in conjunction with accompanying drawing technical solutions of the utility model are described in further detail.
