Hello, friends, I am Muhammd Jawad Hussain and you are reading the blog of ELECTRIC POINT in this video you will learn to repair LED bulb different types of LED bulbs are available in the market if you haven't subscribed our channel, please subscribe so let's start the video previously mercury bulbs was used ... and their efficiency was too low then CFL came which are more efficient than mercury bulb but nowadays LED bulbs are really common LED bulbs are made up of LED (light-emitting diode), that consumes less power LED bulbs have an efficiency greater than 80% LED bulbs are long-lasting no harmful chemical used in the manufacturing of LED bulbs whereas mercury is used in CFL, which is not environment friendly that's why LED bulbs are safe to the environment.
so let's start to repair the LED bulb it mainly consists of two parts
1. Driver (Power Supply)
2.LED's first of all check it Driver to check the driver, you have to ensure whether it is converting 220v AC to low voltage (in this case 52v) in this video driver is working as it converts 220v to 52v now we will check its individual LED's they are called SMD LED's they work on the constant current of 300mA they are too sensitive to currency fluctuation and damages instantly all these LED's are connected in parallel you have to check the voltage on both pins of LED's the difference of this voltage should be around 3V if you find any LED that drops either much greater or less than 3V, then the LED is faulty you can see reading around damaged LED. In one pin it measures 42V and in other, it measures 0V so this LED is damaged and it is consuming around 42V
