When using phosphor and LED, it will distribute the phosphor around the semiconductor chip. The main purpose of this technology is to finish the wavelength conversion of phosphors. Collocation in the application of LED and fluorescent powder, the first need for phosphor gel dispensing operation to facilitate the application of LED automatic dispensing machine to complete. Generally speaking, we will be using epoxy resin to phosphor to gel. Then we use the laser transformation of the fiber to make the phosphor become a yellow luminous body. The remaining blue light will become the white light we usually see after it is mixed with the phosphor. The use of phosphor and LED can not only greatly improve the manufacturing cost, but also produce a good color effect. From the above can know blue LED as complementary color, color in work need to pay particular attention to is the adjustment of the ratio of epoxy resin and phosphor. The amount of the phosphor is appropriate, and the thinness of the fluorescent gel after mixing can not be too high. Otherwise, the pipe will be blocked and the amount of the glue is uneven, which will affect the speed of the LED glue dispenser and the quality of the glue.
