Abstract:
1. An electronic device capable of controlling light-emitting diodes (LEDs) to emit ultra bright light, the electronic device comprising: a power source configured for providing various voltages to components of the electronic device; a signal producing unit configured for providing an operational signal; a micro control unit (MCU) configured for outputting a normal brightness control signal and an ultra brightness control signal according to the operational signal and terminating the output of the ultra brightness control signal after a predetermined time; a pulse current controlling unit configured for controlling to output a first current according to the normal brightness control signal and the ultra brightness control signal and output a second current less than the first amount of current according to the normal brightness control signal after the ultra brightness control signal is terminated; a LED illuminator array comprising a plurality of LEDs connected in series and driven to emit light by the first amount of current and the second amount of current respectively.
