1. LED energy-saving lamps require corresponding heat sinks. In the case that the heat generation of the LED chips itself is not greatly improved, it is necessary to further develop the structure of the heat sink and the application of heat pipe technology.
2, LED energy-saving lamps, the price is too high, LED single price, aluminum radiator, high-efficiency constant current power supply, high light transmittance soft lampshade, the four cost collectively push up the LED cost.
3. At present, the power indicated by most LED energy-saving lamps is the sum of the power of the LED chip itself, not the input power of the power supply. Some bad manufacturers are driven by inferior rectifier circuits, which will cause the actual energy consumption of LED bulbs to far exceed the level of energy-saving lamps and even close to incandescent lamps. Some brands have found 3W energy-saving lamps on the market, using 220V power supply input current up to 90mA (19.8W).
