Description

A kind of LED lamp radiator of easy heat radiation

Technical field

The utility model relates to a kind of LED lamp radiator, and more particularly, it relates to a kind of LED lamp radiator of easy heat radiation.

Background technology

Traditional indoor and outdoor illumination adopts incandescent lamp or electricity-saving lamp (neon tube lamp) usually, and its relative energy consumption is higher; Along with the progress of electronic technology, utilize the lighting of High Power LED (LED) combination more and more general; Because LED utilizes the luminescent properties after the semiconductor energising luminous, have low in energy consumption, the advantage of long service life, thereby become the emerging light source that substitutes the traditional lighting light source.With the light fixture of LED as light source, need to solve heat transfer and heat dissipation problem in the LED use, the radiating efficiency of radiator directly influences service efficiency and the cost of LED; Therefore, exploitation adapts to the various LED lamp bodies and the accessory thereof of LED lamp processing request, convenient combination processing, and applying of LED lamp had conclusive effect.

The utility model content

The technical problems to be solved in the utility model is the above-mentioned deficiency at prior art, and the LED lamp radiator of the easy heat radiation of a kind of good heat dissipation effect, the multiple LED light fixture of one-tenth of many uses, capable of being combined is provided.

The technical solution of the utility model is such: a kind of LED lamp radiator of easy heat radiation, the aluminium alloy body that comprises cylindricality, periphery at the aluminium alloy body is distributed with heat-dissipating fin radially along aluminium alloy body axis, and the heat-delivery surface of wherein said heat-dissipating fin is minor undulations or spiculation.

In the LED lamp radiator of above-mentioned a kind of easy heat radiation, described aluminium alloy body is a cylindrical shape, and described heat-dissipating fin is evenly distributed on the outer surface of aluminium alloy body.

In the LED lamp radiator of above-mentioned a kind of easy heat radiation, wherein at least one end of described aluminium alloy body is provided with threaded joints.

After the utility model adopts said structure, by rectilinear heat-dissipating fin outer surface minor undulations or laciniolate heat radiation projection are set with aluminium alloy body periphery, under identical volume, can strengthen area of dissipation greatly, improve radiating effect, heat transfer and heat radiation when helping the work of LED lamp; Novel simple in structure of this use, radiating effect ideal, and can directly adopt the drawing moulding is for the popularization of LED lighting provides a kind of feasible technical scheme.
