Common Problems with Glowing Diodes Are

Have you encountered a lot of problems that do not understand, and what are the more common problems? Why can't the light-emitting diode be overvoltage or overcurrent uses white light LED? Simply put, it is explained by the most commonly used 5mm white light LED. Its normal working voltage is mostly within 3.0-3.5V range, and the normal working current is 20mA 20mA. However, many people mistakenly think that the use of white light LEDs with over -voltage or overcurrent will be brighter, and the actual test result is that after 15mA, the optical flux increases sharply. After 20mA, there is almost no see -through. But there are obvious fever. There is also a test of life: 20mA has worked for a month, and the attenuation is only 5%. Now there are 95%optical flux. When 30mA work until 19 days, the volume of the light is only 50%. It can be considered that a white light LED that can work 100,000 hours under normal conditions is used in large currents, with a life span of only 600 hours! LEDs can be used for more than 50,000 hours in general descriptions, and some manufacturers claim that Its LED can operate about 100,000 hours, but this does not guarantee that LED products can be used for so long. The wrong operation and process can easily“Destroy”LEDs, LEDs will gradually degenerate over time. Some predictions show that high -quality LEDs can maintain more than 60%of the initial light brightness after 50,000 hours of continuous operation. To extend the life of LED, it is necessary to reduce or completely dispel the thermal energy generated by the LED chip. Thermal energy is the main reason why LED stops operating. This is explained for the use of light -emitting diodes. For more information, please contact online customer service consultation more information.
