Description
Technical field
The utility model relates to a kind of LED radiator, relates in particular to the LED radiator of a kind of light weight and perfect heat-dissipating.
Background technology
The LED radiator generally includes a base and is located at the LED substrate on the described base and is arranged on most integrated LED light source sheets on the described LED substrate, and described base is used for heat radiation, makes the integrated LED light source sheet remain on lower operating temperature.But, the base that existing LED radiator is equipped with all be entity or the sun flower-shaped, by passive from inside to outside the spreading out of of thermal source part, contact with air and cool off up to material surface, thereby realize heat radiation, and this passive type conducts heat and reach radiating effect, it is very slow to dispel the heat, and because of will reaching the heat sink material that heat that every watt of LED produces must be equipped with certain area, and will must be big with the contact area of air.The heat sink material that causes needs to be equipped with is heavy and volume is big.
Industry is in order to improve above-mentioned defective, usually in the centre of base one through hole is set, to accelerate radiating rate, but because of the inwall of through hole is non-hollow out design, so the air in the base plate through holes can outbound flow, but the outer air of base can not promptly can not be realized cross-ventilation toward stream in the through hole, so still have the slower shortcoming of heat radiation, and heat dispersion is not good.
And base makes with aluminium usually, so still heavier.
Therefore, be necessary to design a kind of new LED radiator, to improve above-mentioned defective.
