Hello! If you like, you can order it directly Welcome to your coming If you have any unclear questions, you can ask customer service I wish you a happy lifeFull-size LCD retrofit LED LCD light bar 15-24 inch LCD upgrade LED package. The simple understanding is LCD refitting LED: it is to change the LCD tube in the LCD screen to LED light bar, and change the LCD circuit of the power board to an LED constant current board. Special reminder: When you modify the wiring, please pay attention to the definition of the booster board. Don't see the connection wire is black and think it must be the ground wire because the two ends of the connection wire are different, so consider the definition as the standard! Note: Please have a certain amount of hands-on ability, exploration spirit, and basic circuit knowledge. Although the installation and modification are not complicated, we can't answer you one by one, such as what is a high-voltage bar, or online support. Solve all your installation problems, please be careful if you don’t know about it. [Constant current board specifications] 7cm*2cm (length * width) constant current board, also known as LED booster board, this is a buck board, dimmable type [Lamp strip specifications]: 488mm*4mm*3mm (length * width * height) (87 lamp beads / strip) [Input voltage]: 10V~30V wide voltage [Accessories list]: LED light bar * 2 pieces + dimmable constant current board + connecting wire [Definition of cross flow board]: 1-2 red wire power supply VCC 3 O/F yellow wire switch signal 4 ADJ yellow wire brightness control 5-6GND black wire ground [Why is it universal?] This light bar has 3 LEDs and 1 group, which can be shortened freely according to actual requirements. For example, the 19-wide screen is usually about 420mm, so we only need to follow the rule of 3 LEDs in 1 group. , Just cut to the right length, very convenient! ! It can be retrofitted to most LCD screens on the market, the width can just be placed in the original LCD slot (generally there are two thickness of the screen slot, one is 7mm, the other is 9mm thickness, this model can be installed), using double-sided tape Can be fixed, easy to install, extremely bright, easy to modify, (Many friends ask, how do you know which light bar should be replaced? Here is a brief introduction, 1: check the length of the light bar, the length of the light bar is equal to the length of the original tube, 2: check that the input voltage of the constant current board is 12- 19V, this voltage is equal to the input voltage of the original high-voltage board) (How to modify? How to modify this set is actually not complicated. The LCD circuit of the original power supply board is the LED constant current board in the kit, and the focus is to correspond to the four pins of power supply/ground/boot/brightness in the LCD screen. , Replace the original LCD lamp tube with LED lamp bar. If it is a universal 12V power supply driver board, this set can be directly plugged into the driver board, which is equivalent to directly replacing the original (high-voltage bar + tube), the original high-voltage How to insert the strip, just how to connect this set~~, remember that there is an interface definition at the interface of the constant current board, just connect with the driver board according to the definition)
