The Reason Why the LED Light Source Module Appears Unstable

The changing range of LED lamp bead VF is not considered, resulting in low efficiency of the lamp, and even the price load of the LED light source module in unstable LED light source module. It is generally composed of several LED string of LEDs. quantity. LED's VF changes with temperature changes. Generally, at the constant current, VF becomes lower at high temperature, and VF becomes high at low temperature. Therefore, the working voltage of the LED lamps load at high temperature corresponds to VOL, and the LED lamp load load operating voltage at low temperature corresponds to VOH. When choosing the LED drive, the driver's output voltage range is greater than VOL VOH. If the price of the LED light source module to the large output voltage is lower than VOH, the tolerance of the lamp at low temperature may not reach the actual power. If the selected LED drive to the low voltage is higher than VOL, the drive may be driven at high temperature at high temperature. The output exceeds the scope of the working, the work is unstable, the lamps will flash, etc. But comprehensive cost and efficiency consideration, you cannot blindly pursue the range of the LED driver's ultra -wide output voltage range: because the driver voltage is only in a certain range, the drive efficiency is the highest efficiency. After exceeding the range, efficiency and power factor (PF) will deteriorate. At the same time, the design of the output voltage range of the driver is too wide, which will lead to increased costs and efficiency cannot be optimized. If the power balance and reduction requirements are not considered, the nominal power of the LED drive refers to the data measured by the rated environment and the rated voltage. Considering that different customers will have different applications, most LED drive suppliers will provide a power reduction curve on their own product specifications (common load VS ambient temperature drop curve and load VS input voltage reduction curve)). The red curve indicates that when the price of the LED light source module is input 120VAC, the power reduction curve with the ambient temperature changes. When the ambient temperature is lower than 50 C, the driver allows 100 full loads. When the ambient temperature is as high as 70 C, the driver can only reduce the load to 60%. When the ambient temperature changes between 50-70 C, the drive load of the drive is with the temperature with the temperature with the temperature Rise and linear decline. The blue curve indicates that when the LED driver enters 230VAC or 277VAC, its load has a power reduction curve with the changes in the ambient temperature. The blue curve means that when the LED driver is 55 C, the output power reduction curve with the changes in the input voltage changes. When the input voltage is 140VAC, the load of the driver allows 100 full loads, and as the input voltage is reduced; if the output power remains unchanged, the input current will rise, resulting in the increase in input end loss, the efficiency decreases, the temperature of the device will rise, the individual temperature points may be possible. Excessive standards may even cause devices to fail. Therefore, when the input voltage is less than 140VAC, the output load of the driver is required to be reduced with the input voltage and the linear decrease. After understanding the upper reduction curve and the corresponding requirements, when choosing the price of the LED light source module, you should comprehensively consider and choose according to the actual environmental temperature and input voltage conditions, and leave appropriately to leave the reduction of the reduction of the reduction of the reduction amount.
