Abstract
An automatic heat dissipation LED reflector lamp comprises a lampshade, a radiator, a heat dissipation fan, a thermoelectric thin film, an energy storage capacitor and a voltage-regulator tube. The radiator is arranged at the tail end of the lampshade. A heat dissipation cavity is defined by the circumferential wall of the radiator, the top wall of the radiator and the bottom wall of the radiator, wherein a plurality of heat dissipation circular holes which are evenly arrayed in the circumferential direction are formed in the circumferential wall of the radiator, and the top wall of the radiator and the bottom wall of the radiator are respectively provided with a plurality of evenly-distributed heat dissipation through holes. The thermoelectric thin film is attached to the back face of a substrate, and the thermoelectric thin film is electrically connected with the heat dissipation fan through the energy storage capacitor and the voltage-regulator tube in sequence. Electricity is generated through the temperature difference produced when the LED reflector lamp works, when the voltage of the energy storage capacitor is larger than the breakdown voltage of the voltage-regulator tube, the heat dissipation fan starts to work so that the temperature of the LED reflector lamp can be lowered, and when the voltage of the energy storage capacitor is smaller than the breakdown voltage of the voltage-regulator tube, the heat dissipation fan stops working. The automatic heat dissipation LED reflector lamp is good in heat dissipation effect, high in heat dissipation speed and beneficial to energy conservation and environment protection.
