Description

A kind of LED lamp of radiator structure improvement
Technical field
The utility model relates to a kind of illuminating lamp, particularly a kind of LED lamp of radiator structure improvement.
Background technology
At present, the LED lamp of high-power (more than the 1W) can only be converted into luminous energy with about 10% input power, all the other 90% have changed into heat energy, if heat energy can not leave timely and effectively, to cause the device chip temperature too high, cause a series of disastrous effects, as quicken Embedding Material and wear out, the speed-up chip light decay, simultaneously because a large amount of heat accumulations, thermal stress can make the LED lamp damage, thereby causes LED to shorten device lifetime, heat dissipation problem has become the key in the high-powered LED lamp dress envelope, and other of LED lamp used as also there is same problem in LED display etc., and in order to address this problem, the radiating mode of employing has following two kinds at present:
A kind of is to install aluminium radiator fin additional: this mode is fit to low power illuminating product heat radiation, after temperature reaches suction, heat radiation balance, temperature is basicly stable, temperature no longer rises, thereby plays the effect of heat radiation, and the advantage of this mode is simple, easy for installation, but its volume is big, when the power of product increased, the volume of radiator was restricted, and cost increases.
Another kind is to install aluminium radiator fin and fan additional: this mode is used in the relatively large illuminating product of power usually, after fin increases fan, increased the convection current of air, thereby play radiating effect, but this mode volume is big, and bigger noise is arranged, the life-span of fan is short, after fan is bad,, cause the damage of product easily as untimely replacing.
In a word, two kinds of above-mentioned radiating modes can only make the temperature of device drop near environment temperature, and radiating effect is undesirable, and the volume of radiator structure is big, is unfavorable for the miniaturization of product.
Summary of the invention
