Abstract

The invention discloses a flashlight module and a flashlight power module. The flashlight power module is used to supply power to the flashlight light source that emits light, and the flashlight power module includes a protection circuit for receiving a first voltage and a first current, and for boosting and transforming the first voltage A second voltage is obtained and output, and the second voltage is used to charge an energy storage module to obtain a third voltage, and the third voltage is used to supply power to the flash light source. The protection circuit includes a pulse modulation unit for outputting a pulse signal, the protection circuit performs boost conversion for the first voltage corresponding to the pulse signal, and the duty cycle of the pulse signal is based on the first current make adjustments.

Description

technical field [0001] The invention relates to a light source applied to photographic equipment, in particular to a power supply device for a flashlight module. Background technique [0002] At present, general photographic equipment needs to use a flashlight, which provides high-brightness light for the camera in an instant, thereby improving the video quality. Since camera equipment is a portable and movable device, a flashlight generally uses a battery pack as its power supply. [0003] In view of the high instantaneous driving voltage required by the flashlight, at present, a large-capacity energy storage capacitor is charged, and then the energy storage capacitor provides an instantaneous high voltage for the flashlight light source. Therefore, the control of the charging time for the energy storage capacitor will directly affect the working efficiency of the flashlight. At present, the charging time of flashlight charging modules is long and the charging efficiency ...
