Background
In recent years, with the development of micro-motion pictures, LED photography lamps have generally entered the photography field, and their applications are increasingly widespread. Photographic lights are also known as headlights, interview lights, news lights and function as flashlights in digital cameras. When the object with a dark surface is shot, the auxiliary light sources are necessarily used, otherwise the definition of the picture is influenced, and the improvement cannot be realized by the post-processing. The function of the photographic lamp on the digital video camera is similar to that of the flash lamp in the digital video camera, and when a dark object is needed to be shot, the auxiliary light sources are necessarily used, otherwise, the noise is very large, and the light is not enough to be processed in the later period. For many novices to digital cameras, the camera light appears to be a redundant item that is not too large and is also the most easily overlooked digital camera accessory. This is also because there are too few photographic lamps available in the market, and with the addition of the photographic lamp, the digital camera is not very convenient to carry, is slightly idle and troublesome, and is very popular with many users.
With the development of electronic technology, the field of photography has changed day by day, and from cameras using film to current single-lens and mini-lens cameras, and nowadays, the life of the material is rapidly advancing, and the cameras are not available in entertainment companies, news media, newspaper agencies, magazine agencies, and movie buildings. When a camera is used for shooting pictures in a studio, the camera lamp can be used, the existing camera lamp comprises a lamp body and a lamp holder, 1-4 light sources are mounted on the lamp holder, basically, flash lamps or halogen lamps are adopted as the light sources, the power consumption is large, the size is large, the weight is heavy, the lamp holder is inconvenient to move, meanwhile, the brightness of the light sources needs to be adjusted according to the surface brightness of different objects and the shooting requirements in the shooting process, and the operation is inconvenient because the light sources on the existing lamp holder are controlled by a switch, when the brightness of the light sources needs to be adjusted, the adjustment can be realized only by increasing or decreasing the number of the flash lamps or the halogen lamps.
