LED diffuse reflector light bar is a new type of backlight product with higher brightness and larger luminous angle made on the basis of conventional LED patch. LED diffuse reflector light bar has been widely used in life, in some supermarkets and subways Bus stop light boxes are used a lot. LED diffuse reflection light strips are generally made of high thermal conductivity aviation aluminum substrates, high-power 2835 lamp beads as light sources, and special PMMA optical lenses are added. The main advantage is that the combination of ultra-high brightness The 170-degree wide-angle light emission can obtain the optimal luminous flux and light source distribution optimization with fewer lamp beads or light strips per unit area. After understanding the LED diffuse reflection light strip, it is more conducive to troubleshooting after its failure. The following is Solutions for some LED diffuse light strip failures.

1. After the LED diffuse reflection light strip is installed, the light will flash when connected to the power supply. What is the situation?

There are three kinds of problems: 1. The power of the power supply does not match, and the power is small. 2. It is caused by poor contact during wiring. 3. The power supply is broken.

2. The wiring of the LED diffuse reflection light strip is too long, the front section is brighter, and the rear section is darker.

Answer: If there are too many light bars in series and the wiring is too thin, this will also happen. If there are too many light bars connected, the front-end voltage will be normal and the back-end voltage will be insufficient. Connect a loop so that the voltage of the light bar can be balanced.

3. After the LED diffuse light strip is installed, there will be shadows on the canvas.

A: There is a shadow between the light bar and the light bar, because the distance between the light bar is too large, so that the light bar cannot be illuminated. Just adjust the distance of the light bar.

4. After the LED diffuse reflection light strip is installed, the power supply does not light up.

Answer: The reasons for this situation are: 1. The positive and negative poles are reversed. 2. Short circuit. 3. If a single light does not light up or a few do not light up, it means that the copper bracket of the circuit board is broken, the resistor is broken, and the lamp bead is burned. Solutions, snips, plugs into new ones.
