LED constant current drive, LED is 2 ~ 3 volt low voltage drive, must design complex transformation circuit, different USES of LED lights, should be equipped with different power adapters. In the international market, foreign customers have very high requirements on the efficiency conversion, effective power, constant current accuracy, power life and electromagnetic compatibility of LED drive power supply.

A good LED energy-saving lamp should be composed of four parts: high quality LED chip, constant current isolation power supply, appropriate radiator relative to the lamp power, light diffusion effect soft and spotless light source lampshade. LED chip, good LED chip, high light efficiency, low temperature rise, high color rendering index, high junction temperature, antistatic. Heat dissipation, if the LED is a cold light source, do not need to heat dissipation, it is completely wrong, in has not developed a real low heat LED chip.

Now LED is also described in this unit, for example, an LED is 15000, the unit is mcd, 1000mcd=1cd, so 15000mcd is 15cd. The reason why LED is expressed in millicd (mcd) instead of cd directly is that the earliest LED was relatively dark. For example, in 1984, the luminous intensity of the standard 5mm LED was only 0.005cd, so it was expressed in mcd. The disadvantage of using luminosity as a "brightness" is that if two leds with identical cores, the intensity of luminosity will be higher. Therefore, users should not only focus on the high I value when buying LED, but also on the irradiation Angle.

Because the traditional street LED energy-saving system has a low degree of intelligence, poor communication stability, waste of lighting resources and other problems, it is still mainly inefficient lighting, and the energy utilization rate of street LED in major cities is generally not high, so that the electricity and management costs of street LED have become a huge financial expenditure of the government.In the lighting system energy-saving technology development, foreign lighting energy-saving technology is mainly to promote green lighting, the use of new light source materials.
