LED backlight light bar details introduction£º
Double-sided tape has been attached to the back of the light bar!
Reminder: The original machine has 2 light bars, so you need to replace both of them. Remember~ the three-in-one common fault current is too large, so you must change it to a small current. (Do not know how to ask customer service. Thank you 1)
Special attention: Please select the size according to the above picture, and confirm the rated current and voltage. (This current is not the current required by the light bar to work, but the rated current; the output voltage of the original constant current board needs to be within plus or minus 10% of this voltage)
Without affecting the brightness, the smaller the current, the better. It is better for ZUI to supply power to the light bar with 60%-80% of the rated current. Too small current will cause the light bar to flicker or be very dark, and too much current will cause the light bar to heat up and its service life will not be long. If the original constant current board is not automatically boosted, the voltage will not light up if the voltage is too low, and the lamp beads will be burnt out if the voltage is too high. Please know before shooting!
Before buying the light bar, please tell the customer service about the length, width and thickness of the light bar, the voltage value and current value of the light
The red wire is connected to the positive pole of the power supply, and the black wire is connected to the negative pole of the power supply.
If the output voltage of your constant current board is similar to the voltage of our light bar, you can use it in parallel; if the voltage is greater than about twice the voltage of the light bar, you should use two light bars in series, and use in parallel to easily burn the light bar.
Generally, it is best to change two at the same time, so as not to use light bars with different parameters to produce uneven light, which will affect the picture quality and delay the maintenance time.
The constant current board is divided into two categories, one is the light bar below 24 inches with 12V power supply, and the other is the light bar above 32 inches with 24V power supply.
The light bar mainly depends on the length, voltage and current value. If your light bar parameters are similar to ours, you can take a picture without customer service, and tell us your parameter value on Wangwang, so that you can send it to you. Suitable light bar
