Patent ID: 7300187

Claim:
A light emitting diode (LED) device comprising: a shade having a cavity; an active heat-dissipation device mounted in the cavity in the shade and having a cooling board mounted in the cavity in the shade; an evaporator mounted to the cooling board; a condenser contacting the shade and in which a holding refrigerant is set; a compressor mounted in the shade and compressing the refrigerant in a gaseous state when operating; and an expansion valve expanding the refrigerant in a liquid state when operating; and an LED module mounted to the active heat-dissipation device and having at least one LED; wherein the evaporator, condenser, compressor and expansion valve connect to each other to form a loop in which the compressor connects to the condenser, the condenser connects to the expansion valve, the expansion valve connects to the evaporator, and the evaporator connects to the compressor, and the refrigerant flows in the loop when the active heat-dissipation device operates.
