摘要:
The invention relates to an electroluminescent device for emitting light having an adjustable color point. An electroluminescent region (1) emits light in response to a lighting current and a heating element (7) applies heat to the electroluminescent region A heating control unit (9) controls the heating element (7) in applying the heat in order to adjust the color point of the emitted light. The color point of the light emitted by the electroluminescent device is dependent on the temperature of the electroluminescent region (1). Since the electroluminescent device comprises a heating element (7) for applying heat to the electroluminescent region (1) and a heating control unit (9) for controlling the heating element (7) in applying the heat, the color point can be adjusted in a simple way by using the heating control unit (9).
