What Are the Requirements for ACLED Light Source Module and Power Supply

Nowadays, LED energy -saving products have been recognized and favored by the user in the renovation of street lights, and vigorously promoted the development of LED street light modules. However, in the actual use of LED street lights, it can be found that the actual application of many street light power supply is not optimistic. As an important part of the LED street light, the ACLED light source module has a great impact on the service life of the power supply on the environmental factors and the installation of grounding. Another point is to analyze the fault encountered in the use of the LED street light power module, and put forward some personal technical suggestions, hoping to contribute to the development of LED street lights. The principles of LED street lighting source modules and power supply matching and requirement LED lights and LED street light power supply has become a energy -saving lighting system that countries are promoting and applied, but the matching of LED street lights and power supply has a lot of attention. What are the requirements for the matching of the lamp waterproof power on the LED street light source module? The ACLED light source module and the driving circuit not only have a certain output of the LED, but also have a high conversion efficiency. The requirements are very harsh, LED is not like ordinary incandescent lamps, and can directly connect to 220V AC market electricity. LED is a low -voltage power driver of 2 to 3 volts, so you need to design complex transform circuits. Different LED lights need to be used. Different power adapters are required. The following is the requirements and principles of the LED light matching power supply: the principles of the power supply of the ACLED light source module must be followed 1. The output current of the driving power supply that matches the LED light source module must be stable, and the deviation cannot exceed the rated output current if the IF out of the IF out 3%(including under high and low temperature environment). 2. Drive power that matches the ACLED light source module must be a constant current power supply. 3. The rated output current IF that matches the LED light source module IF needs to meet the following relationship: 0.85if total IF 0.9if. 4. The LED light source module installed on the same lamps should be selected with the light source of the same position (BIN) without special requirements; A total of the LED light sources in group M, and each group is composed of N LED light sources connected. The principle that the LED light source that is connected by group M is: the voltage of the two ends of each parallel group LED needs to be equal or close to it. If the voltage of the two ends of each parallel group LED is large, this will cause the current distribution between the two groups with a large voltage difference between the two voltage differences.
