1, LED energy-saving lamps need the corresponding radiator. If the heat consumption of the LED chip itself is not greatly improved, we need further development of the radiator structure and the application of heat pipe technology.
2, LED energy-saving lamps, the price is too high, the price of LED monomer, aluminum radiator, constant current power supply, high transmittance and soft shade, the four cost of the collective push up the cost of LED.
3, most of the LED energy saving lamps indicate the power of the LED chip itself, not the input power of the power supply. Some bad manufacturers are driven by inferior rectification circuit, which will cause the actual energy consumption of LED bulbs far beyond the energy saving lamp and even close to the incandescent lamp level. Some brands of 3W energy saving lamps have been found on the market, and the input current of 220V power is as high as 90mA (19.8W).
