Power-adjustable photoflood lamp device

Abstract

The invention relates to a power-adjustable photoflood lamp device belonging to the field of photographic equipment. The photoflood lamp device comprises a microprocessor U7, and the microprocessor U7 is respectively connected with a display circuit A, a flashing circuit B, a synchronized trigger circuit C, a power source detection circuit D, a model bulb circuit F, a charging and accumulating circuit H, a temperature protection circuit I and a flash trigger circuit J. The synchronized trigger circuit C and the power source detection circuit D are respectively connected with a voltage regulator circuit K, the microprocessor U7 is connected with the flashing circuit B through a potential device RW1, and the microprocessor U7 is also connected with a charging indication circuit E, a voice prompt circuit G and a charging detection circuit L. Compared with the prior art, the power-adjustable photoflood lamp device has the characteristics of reasonable design, simple structure, convenient use, low photographic cost, good illuminating effect and the like.

Description

technical field [0001] The invention relates to the field of photographic equipment, and specifically provides a photographic light device with adjustable power. Background technique [0002] In the photographic lights in the prior art, the flash light usually uses one brightness, that is, a flash light of one power is used as illumination under any circumstances. Such a design not only affects the photographic effect, but also wastes resources greatly. , and have an impact on the life of the flash. And trigger the flash tube to flash when the control system of the flash is all normal, but when the flash tube does not actually emit light, there is no supporting device to warn it at present, which is inconvenient for photographers. Contents of the invention [0003] The present invention aims at the above deficiencies, and provides a power-adjustable photography light device with reasonable design, simple structure, convenient use, low shooting cost and good lighting effec...

[0002] In the photographic lights in the prior art, the flash light usually uses one brightness, that is, a flash light of one power is used as illumination under any circumstances. Such a design not only affects the photographic effect, but also wastes resources greatly. , and have an impact on the life of the flash

Moreover, when the control system of the flash is normal, the flash tube is triggered to flash, but the flash tube does not actually emit light. At present, there is no supporting device to warn it, which is not convenient for photographers to use.
