An illumination apparatus using an LED is provided to change a color temperature and a brightness of an output beam by detecting a peripheral temperature and a peripheral brightness. A main body includes a bottom plate and a housing(13), which is assembled to the bottom plate. A board is installed in the main body. Various electronic components, such as a dimming controller and a microcontroller, are mounted on the board. An optical source includes a first LED(Light Emitting Diode) module(51) and a second LED module(53), which are mounted on the board. The first LED module includes plural LEDs, which emit light with a color temperature lower than 2000K. The second LED module includes plural LEDs, which emit light with a color temperature higher than 8000K. |
