Film and television lighting often has three meanings. One is to improve the brightness of the object to be illuminated, improve the dark shooting environment, and improve the image quality, which is also the most basic one. The second is to shape the light and shade of the subject and create a three-dimensional sense of the picture. The third is to use different lighting methods to artistically describe the subject to express a specific artistic effect. Although the technical function is the simplest, it is only to illuminate the photographed picture, there is still a lot of knowledge on the film and television lighting itself, which is why professional film and television lighting is gradually different from other ordinary continuous lighting.

In the scene of film and television production, especially outdoor shooting, the brightness of natural light is often unpredictable and uncontrollable. The color temperature of natural light is also changing as time goes by in the morning, noon and dusk. From this point of view, film and television lighting is often required to have high and the brightness that can be finely adjusted, as well as a wider range of color temperature adjustment. In addition to catering to changes in natural light, color temperature adjustment can also actively simulate scenes with different color temperatures, such as early morning, noon, dusk, bonfire, key light, etc. The artistic effect is to achieve a retro shooting atmosphere.
