Can the light source of the library be led?

No LED fluorescent lamp is needed. First, the price of this lamp is much higher than that of ordinary poles, and its service life is not as long as that of poles. (At present, many LED fluorescent lamps produced by small factories are driven by capacitor step-down, which is not reliable and easy to breakdown. ). Another reason is that most of the current white LEDs are powered by a blue LED to emit blue light, and then the fluorescent powder around the die is fired to emit white light, so a small amount of blue light will leak out, and blue light is high-energy light, which is not good for vision. Therefore, LED fluorescent lamps are used less as light sources.
