Reflow soldering red light bead LED bulb

When the RGB is separated, it can be controlled separately. Although it can be directly controlled and the color mixing is good, it is a big problem to achieve the pure white light LED bulb. Although the cost is expensive, the quality is relatively good. As for the white LED lamp, although The cost is cheap, and it can directly replace CCFL and become the main technology of LED. However, relatively speaking, because of the wavelength and frequency issues, they are packaged together, so the scattering situation will be unstable SMD LED.

The control problems of RGB lights still need to be strengthened. For example, if one of the lights is broken, it will be quite obvious on the entire screen. On the contrary, white LED lights can complement each other because they are side-shooting, so they can make up. A broken LED, and the uniformity of the compensation, so that the overall situation does not look too bad SMD LED lights.
