What do you know about LED panel lamp power supply
Main requirements of LED panel lamp driving power supply
1. Double high, namely: high power factor (PF) and high conversion efficiency. Products with PF = 0.9 or above have far exceeded the standard requirements of power grids around the world, so as to reduce the pollution to the power grid; for products with high conversion efficiency, the electric energy is converted into light energy to a greater extent, and the heat loss is reduced.
2. The power supply is divided according to the voltage connected: wide power supply
Voltage power supply - the so-called wide voltage means that it can adapt to most normal working voltage. Generally speaking, the range of wide voltage is 85-265vac or 100-265vac;
3. Narrow voltage power supply: the so-called narrow voltage power supply is actually relatively speaking. The narrow voltage range is mostly 175-265v (there are 185-265v), which are different from different power suppliers.
4. According to the input and output, it can be divided into isolated power supply and non isolated power supply.

How to solve the problem of heat dissipation for LED panel lamp?
In the LED panel lamp, there are three basic stages of heat transfer, from integrated chip to epitaxy, from packaging base steel plate to heat sink or shell. At present, the technical problem of LED heat dissipation is that led nodes are limited by temperature. High temperature will cause led integrated chip, luminous powder, packaging epoxy resin service life is reduced. In order to keep the advantages of high efficiency and long life of LED, the junction temperature of LED must be controlled.
