LED light is still a weak light after the switch is closed. What's the matter?
Check whether the switch is connected to the FireWire, if it is zero line, the LED light will be slightly bright, and the discomfort is to check whether the LED lights have any wires arranged and arranged on other wires. If the fire is left behind, it still turns on, and that may be caused by the induced electricity.
LED how to connect the lamp band, 12 volt battery is not damaged
Direct contact will burn. The three should be connected in series, with 150 ohm resistors in front (power not less than 0.06 watts). Note the positive and negative poles, and the gap is negative.
Can you tell me if the LED light belt can be lit for a long time?
Any light of the LED can be lit for a long time, as long as it meets the requirements of the voltage and current of the LED lamp.
LED lights bring what is high pressure, what is low voltage?
Low voltage LED light belt is 220 volt cross flow, 12 volt DC power supply (with a small converter box), can also be battery or battery power supply, generally with a length of 6---10 meters long, suitable for civilian use. The high voltage LED light belt is 220 volt AC direct power supply, usually 50---100 meters long, suitable for commercial use.
Led how much is the band of light a metre?
See if you want waterproof or waterproof, not waterproof, single PCB lamp, very cheap.SMD5050 lights are used in general light bars. 20-30 yuan, 1 meters
What is a light belt?

How to solve the problem of LED lamp heating problem?
The heat of the LED bulb is introduced here, because any LED can be made into a lamp, so the heat generated by the LED chip is always removed into the air through the housing of the lamp. If the heat dissipation is not good, because the heat capacity of the LED chip is very small, the accumulation of a little heat will make the chip's junction temperature rise rapidly. If the long time work in high temperature state, its life will soon shorten. However, these heat can really lead the chips to the outside air and go through many ways.
