  • Patent number: 10936088
    Abstract: Disclosures of the present invention describe an intelligent brightness modulating device for being applied in a gaming input device like a gaming mouse. The intelligent brightness modulating device comprises a photoresistor and a voltage regulating unit. In case of a resistance of the photoresistor varying with an intensity of an ambient light, the voltage regulating unit is adaptively configured for controlling a light driver chip according to the resistance of the photoresistor, such that a driving power of at least one light unit of the gaming mouse is hence correspondingly modulated with the intensity of the ambient light. By using the intelligent brightness modulating device, not only does the gaming mouse be therefore provided with a power saving function, but eyes of a game player are also protected from being stimulated or hurt by a high-intensity light that is radiated from the light unit.
