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 which is convenient for application of large precision dispensing machine to complete the LED. 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.
As a new lighting tool, the LED in the lighting industry of large LED precision dispensing machine is widely used. Because of its particularity, LED dispensing packaging has been widely applied in the industry. However, this product is more stringent on the demand for glue than the regular dispensing operation. This is the most important glue chip in LED, which has the LED lighting function. If it is exposed to the air for a long time, the whole mechanical performance of LED will decline, and it will even lose its function. Therefore, it is very necessary to carry out precision glue packaging. It is to carry out precision dispensing, so LED lamp package using LED ball bubble gum machine is very important.
When using a large LED dispensing machine dispensing foam ball, we use the glue is epoxy resin, it is because of the characteristics of the epoxy resin is suitable for dispensing work of this type, it can be extremely strong resistance performance, can protect LED lighting chip will not be outside, still can use different ways of dispensing and to change their performance by adding glue scattering agent to control the direction of the light scattering ability, epoxy resin itself has a superior performance, with anti wet glue solidification, high strength, refraction on the optical projection, high efficiency.
