Working principle of tricolor lamp tube

Tri-color flat-leaf lamp belongs to low-pressure gas discharge lamp, and its working principle is the same as that of fluorescent lamp. After the lamp tube is electrified, the emitted electrons and mercury in the lamp tube form an internal circuit loop. Mercury atoms in the lamp tube collide with inert gas and then discharge, which excites 253.7nm ultraviolet rays, which are absorbed by tricolor phosphors and converted into visible light.

Phosphor addition, green and blue tricolor powder and calcium halide powder (common white fluorescent lamps), tricolor lamps identify the same objects compared with halogen lamps. If white fluorescent lamps need "1", tricolor lamps only need "0.7", because the light emitted by tricolor lamps is closer to the optical characteristics of sunlight, and the brightness of human eyes feels better. Tricolor is widely used in life.

For example, daily lighting tubes, photo studios, studios, videos, televisions, movies, studios, etc. Everyone likes the application, because the light it brings is more suitable and closer to the real image.
