Under the premise of not changing the material of LED lighting, within the limit of the LED, the means to increase the brightness is to increase the current. As the current increases, the heat generated by the LED will increase sharply. Anyone who has used LED light source portable projectors or micro-projectors must have a deep understanding of the fact that LED light source projectors are very hot and generally have obvious noise. These products, on the one hand, the body is small, the key is due to its own large heat. How to effectively dissipate heat has become a key problem that LED lighting needs to solve urgently.

The speed of the cooling fan provided by Shenzhen Baishunxin Electronics Co., Ltd. is determined by the number of turns of the coil in the motor, the working voltage, the number of fan blades, the inclination angle, the height, the diameter and the bearing system. The speed of the fan can be measured by the internal speed signal or externally, which greatly improves the adaptability to the environment. It is a cooling mode that is very suitable for LED lamps.
