Description

A kind of LED lamp radiator

Technical field

The utility model relates to a kind of radiator, relates in particular to a kind of LED lamp radiator.

Background technology

LED has energy-conserving and environment-protective, the advantage such as safe and reliable, now has been widely used in the fields such as outdoor brightening, street illumination, advertising lamp box indicator lamp backlight, various, room lighting, and following prospect is very wide.

But along with the increase of LED lamp power, the heat that produces also certainly will increase, if these heats can't effectively shed, will cause LED life-span degradation, and significantly decay of light efficiency.

LED radiator commonly used is the die casting aluminium radiator at present, because its thermal conductivity factor is low, thereby can not reach good radiating effect; Another kind is heat of transformation tube radiator, although it has the characteristics of quick conductive, heat transfer rate is more than 100 times of copper heat transfer rate, and its cost is high, for structure restriction is arranged.

The utility model content

Technical problem to be solved in the utility model provides a kind of simple in structure, and is easy to assembly, and cost is low, heat absorption is fast, and Novel LED light radiator fast, rapid heat dissipation conducts heat.

The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of LED lamp radiator, comprise thermal-arrest layer, heat radiation fin, described thermal-arrest layer and heat radiation fin are integral structures, described heat radiation fin is positioned at the top of described thermal-arrest layer, described heat radiation fin is that up-small and down-big surface is with the laminated structure of wave stripe, the bilateral symmetry position distribution at described thermal-arrest layer middle part has two the first entrance holes, the symmetric position at described thermal-arrest layer two ends is distributed with two lamp stern fixing holes, and second entrance hole and four led light source fixing holes are arranged at described thermal-arrest layer bottom.

On the basis of technique scheme, the utility model can also be done following improvement.

Further, described the first entrance hole is through whole thermal-arrest layer, and is communicated with the second entrance hole.

Further, described the first entrance hole one end inlet wire is added with respirator without an end of inlet wire.

Further, described respirator is one and half ventilating films.

Further, described the first entrance hole, the second entrance hole, respirator form respiratory system jointly.

Further, there is a C type hole that is used for being fixed with lamp stern fixing hole the lamp stern at the middle part of the heat radiation fin of top, described thermal-arrest layer middle part, and there is a power socket top, C type hole.

Further, the material of described radiator is extruded aluminium.

Further, the size of described radiator can change according to the power needs.

The beneficial effects of the utility model are: a kind of LED lamp radiator described in the utility model, simple in structure, easy to assembly, cost is low, heat absorption is fast, fast, rapid heat dissipation conduct heat, this radiator is not subjected to Power Limitation, can make according to actual conditions and user's demand the product of different size, to be applicable to the demand of different capacity LED lamp.

Description of drawings
