The present invention is related to the apparatus for driving the light emitting devices with different colors. The input powers of the light emitting devices are measured and controlled by a feedback control system to maintain constant, and by setting different power inputs to the different light emitting devices different stable colors are produced.

Apparatus for controlling light emitting devices

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.
