Beschreibung
Zusammenfassung:	The illumination device has an LED lighting apparatus having an LED emitting white light and an optical filtering unit for filtering the white light emitted by the white LED. The optical filtering unit has two optical filters having different permeability coefficients for separately filtering the light from the LED. A power supply unit changes the current supplied to the LED based on the filter positioned in front of the LED for correcting color temperature of light emitted by the LED. An independent claim is included for lighting system.
