Abstract
A light-emitting diode (LED) device has a shade, an active heat-dissipation device and an LED module. The shade has a cavity. The active heat-dissipation device is mounted in the cavity in the shade and has a cooling board, an evaporator, a condenser, a compressor, an expansion valve and a refrigerant. The evaporator, condenser, compressor and expansion valve connect to each other to form a loop. The refrigerant is set in the loop. The LED module is mounted to the active heat-dissipation device and has at least one LED. The active heat-dissipation device dissipates the heat from the LED and even lowers the temperature of the LED under ambient temperature.
