Why LED Strip Light Wont Light Up Troubleshooting


Today we'll answer the frequently asked question. "why LED strip light won't light up". If you find your flexible LED strip light won't light up or power up, you may check the following troubleshooting information for help.



1. The lamp beads of led strip light must be broken or damaged during transportation if the light is not covered with full protection.



2. There must be a faulty at the light's soldering points. The soldering may come off if there is any shock during transportation.


3. Soldering with poor quality may cause embrittlement or shedding when the strip light is bent for use.


4. Cheat on tin soldering materials can also cause the same problem as the 2 point we just mentioned.


5. LED lights with flexible installation bending angle is too large, resulting in LED lights with flexible joints and lead to bright copper separation

6. A excessive bending may result in the disconnection between the joints and copper foil.


7. Thick solder layer on strip light's circuit board lead to a non-complete fusion of the soldering and the circuit board.


8. LED Flexible Strip light can not be twisted during installation. The soldering may come off by a twisting.


9. Electrostatic failure. LED is an electrostatic-sensitive component. If there is no good ESD protection measures for LED, the chip will burn out.

Using the TLP250 Isolated MOSFET Driver Explanation and Example Circuits

I’ve already shown how to drive an N-channel MOSFET (or even an IGBT) in both high-side and low-side configurations in a multitude of ways. I’ve also explained the principles of driving the MOSFETs in these configurations. The dedicated drivers I’ve shown so far are the TC427 and IR2110. Some people have requested me to write up on MOSFET drive using the very popular TLP250. And I’ll explain that here. The TLP250, like any driver, has an input stage, an output stage and a power supply connection. What’s special about the TLP250 is that the TLP250 is an optically isolated driver, meaning that the input and output are “optically isolated”. The isolation is optical – the input stage is an LED and the receiving output stage is light sensitive (think “photodetector”). Before delving any further, let’s look at the pin configuration and the truth table. Fig. 1 - TLP250 Pin Configuration Fig. 2 - TLP250 Truth Table Fig. 1 clearly shows the input LED side and the receiving photodetector as well...

Block diagram of AM transmitter and receiver with explanation

Block diagram of AM transmitter and receiver with explanation AM Transmitter : Transmitters that transmit AM signals are known as AM transmitters. These transmitters are used in medium wave (MW) and short wave (SW) frequency bands for AM broadcast. The MW band has frequencies between 550 KHz and 1650 KHz, and the SW band has frequencies ranging from 3 MHz to 30 MHz. The two types of AM transmitters that are used based on their transmitting powers are: ·          High Level ·          Low Level High level transmitters use high level modulation, and low level transmitters use low level modulation. The choice between the two modulation schemes depends on the transmitting power of the AM transmitter. In broadcast transmitters, where the transmitting power may be of the order of kilowatts, high level modulation is employed. In low power transmitters, where only a few watts of transmitting power are required , low...
