Classification by color led module types can be divided into color, colorful, full-color single-point control are three color is a single color modules, generally have red, green, yellow, white, and so is more commonly used; Colorful LED module is made of seven different color conversion module products, which color more and more variability; full-color LED module is more abundant compared to 288, factory direct supply led module, it can achieve full true color changes, not only very beautiful, led module board production house, and dynamic, but also more attractive to the eye. Press the single LED power can be divided into low-power (0.3W or less), medium power (0.3-0.5W), high-power (1W and above) are three low-power high-power modules than on the higher brightness and the use of time longer, the future development trend of LED lighting, led module wholesale manufacturers, but also with practicality. By sealing it can be divided into two kinds of water and not waterproof. Waterproof and non-waterproof module is mainly to see the application environment to distinguish between, Henan led module, waterproof LED modules can be generally used in outdoor lighting and its use, it will not happen because of the water problems, more suitable for harsh Environmental applications without waterproof modules are mainly indoors more. Of course, water is not waterproof module than the price should be higher. The LED LED modules are divided into shape: in-line LED modules, LED piranha module, SMD LED module. In order to adjust the color temperature of white LED light source modules, it is necessary to white LED modules in the blue, green and red 3 LED chip drive current controlled individually, we need three separate constant current drive circuit. Currently, the constant current drive circuit is generally used switch-mode PWM controller to achieve its drive current regulation is divided into analog adjustment mode and PWM adjustment method.
