Abstract
An illumination control device is used in an optical pointer to cooperate with an optical sensor module and a light-emitting device to emit proper illuminance of light. The illumination control device includes a microcontroller generating a supplemental current when the optical pointer is in a power-saving state; and a controlled current amplifier in communication with the microcontroller, the optical sensor module and the light-emitting device for providing an amplified current for the light-emitting device to emit light. The controlled current amplifier amplifies a synthesized current of a light-emitting current generated by the optical sensor module and the supplemental current generated by the microcontroller to obtain the amplified current when the optical pointer is in the power-saving state.
