Description

High-power LED lighting fixture light source module

(1), technical field: the utility model relates to a kind of light source module, particularly a kind of high-power LED lighting fixture light source module.

(2), background technology: modes such as traditional LED lighting light source module uses that aluminium extruded, copper squeeze more, heat pipe and fin welding are made radiator structure; It is simple in structure that aluminium extruded dispels the heat, need not advanced specification requirement, need not build high-tech technical team, need not to drop into development costs, imitateed easily, the product of this kind version occupies the very big market at present, but its heat dispersion is relatively poor, cost is high, structural design has limitation very much, and the bottleneck problem that has cost of manufacture, version during the design more than realizing lamp power 150W, the product more than the design 300W is its impassable obstacle especially; Copper squeezes thermal conductivity factor height, the perfect heat-dissipating of heat radiation, is subjected to technogenic influence can not produce the larger area thermal component but copper is crowded, and copper squeezes and can only be applied in the following product heat radiation of 100W; Heat pipe and fin welding also are to use more radiator structure on the market as radiator structure, and its thermal conductivity is good, heat-sinking capability is better, but for the space requirement high product, its topology layout difficulty is big, higher, the poor reliability of heat pipe price; The only a few product adopts air-cooled active radiating mode, it can improve radiating efficiency greatly, still, and owing to the LED lamp life-span is grown (50,000 hours), working environment complexity, therefore it has higher requirement to fan, and using air-cooledly has the long-term reliability of source heat-dissipating also can't guarantee.

(3), utility model content: the technical problems to be solved in the utility model is: at the prior art deficiency, provide a kind of simple in structure, perfect heat-dissipating, high-power LED lighting fixture light source module that cost is low.

The technical solution of the utility model: a kind of high-power LED lighting fixture light source module, contain led light source plate and radiator, radiator contains horizontally disposed base plate, be connected with a certain number of radiating fin on the side of base plate, radiating fin stretches to the top of base plate, the lower surface of base plate is provided with the led light source plate, and base plate is connected by securing member with the led light source plate.

Radiating fin divides inside and outside two rows to be provided with, interior row's radiating fin all is connected on the side of base plate with the root that effluxes radiating fin, and interior row's radiating fin is crisscross arranged with the root that effluxes radiating fin, efflux radiating fin and upwards vertically stretch, interior row's radiating fin is to the interior top of base plate extending obliquely.

Interior row's radiating fin is the strip radiating fin with effluxing radiating fin.

Base plate is rectangle base plate or square floor, is connected with radiating fin on two opposed side edges of base plate, and these two opposed side edges are upwards dug.

Base plate and radiating fin are integral structure.

The great power LED luminous tube has been welded on the lower surface of led light source plate.

Base plate is provided with a certain number of tapped through hole, and base plate and led light source plate link together by the screw in the tapped through hole, is provided with thermal grease between base plate and the led light source plate.

Show in actual the use, only having under 0.018 square metre the area of dissipation condition, this high-power LED lighting fixture light source module can realize raising up to the power of 70W the load light source of level, by using this high-power LED lighting fixture light source module, can in the confined space that conventional lamp had, realize the above high-power LED illumination product of 500W, remedied the deficiency that light fixture more than traditional kilowatt can not substitute with the LED lamp, make the high power LED semiconductor illumination thoroughly substitute traditional light source.

The beneficial effects of the utility model: 1, be connected with a certain number of radiating fin on the side of base plate of the present utility model, radiating fin stretches to the top of base plate, base plate and radiating fin can be integral structures, when making base plate and radiating fin, can adopt the moulding of high heat conduction panel beating material integrated punching, preparation method is simple, cost is low.And light source board directly contacts with base plate, and the heat that light source board produces can be directly conducted on base plate and the radiating fin, realizes high efficiency heat conduction and heat sinking function by carrying out heat exchange with air then.

2, base plate of the present utility model is provided with a certain number of tapped through hole, can make things convenient for the assembling and the layout of polylith led light source plate, assembling is put just, dependable performance, cost are low, easy to process, can realize the same lamp, the effect that multimode is arranged is for realizing that the standardization in high-power LED illumination market and standardization provide possibility in the future.
