| Abstract | The invention relates to an automatic control device for automobile combination instrument background light, which comprises a light emitting diode illuminating matrix, a triode, a photosensitive sensor and a singlechip. The singlechip acquires an ambient brightness signal via the photosensitive sensor, outputs a pulse signal with a corresponding duty cycle after the signal is processed by software, and drives the triode to adjust the illumination of the light emitting diode illuminating matrix, so that the automobile combination instrument background light is always in the optimal status. The invention is simple and practical, the adjustment is precise and the degree of automation is high. |
