This radiator is rational in infrastructure, and base and heat -conducting cylinder are the graphite material machine -shaping, through the cooperation of graphite material characteristic and fin, have improved radiating effect, have guaranteed LED's life, and simultaneously, the unique design of fin, furtherly have improved the radiating effect, moreover, this radiator stable in structure, the fin is removable, has improved life, has practiced thrift the cost.
Description
Technical field
This utility model relates to heat sink technology field, is specifically related to a kind of LED heat radiator.
Background technology
Development along with photovoltaic industry, LED is widely used in various luminaire because having the features such as low-power consumption, life-span length, easy to control, shock resistance, LED belongs to cold light source, compared with electric filament lamp and fluorescent lamp, also have do not flash, the feature such as toggle speed is fast, energy-conserving and environment-protective, be considered as a new generation's perfect light source by photovoltaic industry；Although LED is considered cold light source, but still can produce certain heat during work, the operating temperature of LED typically should be less than 50 degree, material is had to show, when the operating temperature of LED reaches 55 degree, its life-span can reduce half, at present, generally there is heat dissipation problem in LED of the prior art etc., the service life causing LED is short, easily burn out or fault etc. occurs, in addition, in order to solve the heat dissipation problem of LED, LED installs radiator additional by surface, break up hot glue by bottom and heat is led to outside, structure after some LED are improved is relatively complicated, installing/dismountings etc. are all inconvenient.
Therefore, for the problems referred to above, the utility model proposes a kind of new technical scheme.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of combination, good heat dissipation effect, the LED heat radiator that stability is high.
