LED drive power supply 9901 circuit is composed of electronic components, including semiconductor components, resistance, ED is a cold light source, the working junction temperature can not exceed the limit, and a certain amount of surplus is left in the design. The design of the entire lamp should consider the appearance of beauty, easy installation, light distribution, heat dissipation and many other aspects, to seek a balance point in many factors, so that the overall lamp is good. The development time of LED lamps is not long, there is not much experience that can be learned, and many designs are constantly improving.

Some LED drive power supplies 9901 use power supply for outsourcing or purchase, lamp designers do not know much about the power supply, the heat dissipation space for the LED is larger, and the heat dissipation space for the power supply is small. Generally, after designing the lamps, find a suitable power supply to match, which brings certain difficulties to the matching of the power supply. It is often encountered that due to the small internal space or high internal temperature of the lamp, and the cost control is low, it is impossible to allocate a suitable power supply.
