The existing photography lights have the following deficiencies: 1. The photography lights are relatively single. There are only 5500K white light photography lights and 3200K warm light photography lights. These two types of photography can only be used interchangeably. , the color of the picture taken by the user with a 5500K white light photography light is too white, and if the color of the picture taken with a 3200K warm light photography light is too warm, in addition, due to the quality of the shooting equipment (mobile phone, camera, SLR camera, etc.) Different products have different photosensitive effects, so the color effect of the pictures taken will be biased. In order to make the color effect of the picture better, when the user needs to select the color temperature effect of any value between 3200K-5500K, now photography Light just can't do it.

2. Existing photographic lamps use the volume of the light itself for physical heat dissipation or cooling fins to dissipate heat. The heat dissipation effect is poor. In order to avoid damage to existing photographic lamps due to overheating, existing photographic lamps are controlled The brightness and power of the lamp should not be too high, which eventually leads to the existing photographic lights with low power and insufficient brightness.
