LED Tube light Repairing. Home Utility Circuit 32

1ALED Tube lights are costly lights but susceptible to instant damage. Since it uses an LED Driver and very sensitive LED Chips, voltage fluctuations, voltage surge, over heating etc can destroy it easily. But all the parts of the LED Tube light will not fail, so that we can easily repair it. The major problem may be the failure of one or more LED chips or the driver. By doing some repair works, we can use the LED Tube light again. I found one of my 12 Watts LED Tube light is not glowing and decided to repair it. Now it is working well. Its expense was just Rs.50 for the driver only. See the step wise method of LED Tube light repairing.

LED Tube Light Hacked. Home Utility Circuit 9

LED Tube lights are now commonly used to save energy. These are of different types ranging from 12 Watts to 100 Watts. The LED tube light has an LED panel powered by 12 volt LED Drivers. Each section of the panel consists of three 0.5 W White LED chip serially connected with a 20 Ohms (SMD No.200 ) current limiting resistor. Depending on the power output (Watts), the number of 3 LED sections increase. For example, in an 18 W LED Tube light, there will be 36 Chip LEDs (36 / 0.5 W = 18W). In 100 W LED Light, there will be two hundred 0.5 W LED chips. Two or more LED drivers are used to drive the LEDs. Sometimes the LED Tube light fails to light completely. The main reason is the failure of one or more LED driver. Let us see how to repair an LED Tube light.
