| 摘要 |
The present invention discloses a lamp dimming control device using temperature compensation. The lamp dimming control device includes: a temperature sensor 10 for sensing the ambient temperature of the lamp; a controller 20 for detecting a temperature value of the temperature sensor, comparing the detected temperature value with a minimum power value depending on a temperature, previously set by a program, to decide a minimum illumination intensity, and outputting a dimming control signal with the minimum illumination intensity; a decoder 30 connected with the controller through a communication line, installed in an illuminating device including the lamp, for decoding the output value of the controller to output a signal for controlling the lamp; and a ballast 40 for controlling turning on and brightness of the lamp in response to the output signal of the decoder 30.
