Abstract:
A light emitting diode module providing stable color temperature includes a plurality of light emitting diodes, at least one color sensor and a controller. The plurality of light emitting diodes can emit light with different wavelengths. The light emitting diode module providing stable color temperature includes a reflection region at the path of the light emitting from half peak angle of each light emitting diode. The color sensor detects the light having different wavelengths reflected from the reflection region. The controller adjusts driving currents of the light emitting diodes according to the luminous intensities of the light of the light emitting diodes reflected by the reflection region and detected by the color sensor.
