The LED light strip is cut by mistake and there is a section that does not light up, is there any wa

Workaround: The only way to solve this problem is to replace it with a new one.

The LED light strip must have a double chip to change the color, the bi-color light has two leads into two leads, and the other is a common point, a total of three leads; The tri-color light has three leads, and the other is a normal grounding wire.

There are four clues in total. Two-color and three-color controllers were purchased from the finished product, and each wire was connected according to the port identification, allowing the power supply to control the color change.

Use two lines to connect the ones that you have dropped, and remember that the positive and negative poles are not reversed.

Cut out the part that doesn't shine or buy a new one and connect it.

A wire is attached to the connection point where the two ends are cut.

Circle 2 lines? Connect it with a pin.

Buy a section early and pick it up, or you can shake it a few times underground.

1. The middle part of the LED strip is not bright, most of which is due to the poor heat dissipation of the strip, which affects the durability.

Solution: Only to replace the LED strip with a new one.

2. The high temperature resistance of LED is not good, therefore, if the welding temperature and welding time of LED are not well controlled in the production and maintenance process, the LED chip will be damaged due to ultra-high temperature or continuous high temperature, resulting in the phenomenon of suspended animation of LED light strips.

Solution: Do a good job in the temperature control of reflow soldering and soldering iron, and use a temperature-controlled soldering iron to effectively prevent the soldering iron from burning the LED chip at high temperature.

3. Moisture bursts at high temperature, LED packaging will absorb moisture if exposed to air for a long time, if it is not dehumidified before use, it will be heated and expanded due to high temperature and long time cycle in reflow soldering, causing LED packaging to burst, which indirectly leads to overheating and damage to LED chips.

Solution: The storage environment of LED should be constant temperature and humidity, and the unused LED must be placed in an oven of about 80 ° for 6 8 hours for dehumidification before the next use, so as to ensure that the LED used will not have moisture absorption.

Summary. The LED strip light is connected by multiple groups of LED lights in parallel, and the LED lights of each group are connected in series, after you cut off the joint, you cut off the circuit of the previous group, and the front lights will naturally not light up.

Why is the light strip too long, after cutting off a part, the light strip will not light up.

The LED light bar is connected by multiple groups of LED lights in parallel, and each group of LED lights is connected in series with the remaining socks, after you cut off the joint, it will cut off the loop of the previous group of trembling gears, and the lights in front will naturally not be lit.

The light strip is cut short and the circuit is destroyed, so that it will not be lit, because there must be a loop in the closed middle circuit of the lamp line, and the shortened light strip line is destroyed, resulting in the lack of circuit of the line, so it will not be lit, and after the light strip is shortened, it may be because the voltage of the light bar becomes smaller, and the Hu drive and state block are too large, which will also damage the light bar, so if you don't understand, you can't cut the light bar indiscriminately.

There are two reasons for not lighting up: the first is the problem of the light strip itself, the light strip is soldered, the light is driven and it will not light up when it is moved at an angle, this is a quality problem, it is caused by virtual welding when welding the lamp beads, you can find the seller;; The second reason is that the alloy wire of the power cord pin and the light strip is not fully in contact.

The characteristics of the performance are that the light strip is on for a period and not on for a while. As long as the pin is fully inlet into the lamp wire, it is in full contact with the alloy wire.

That's it.

It depends on what kind of light strip you are, if it is 220V, then you can only cut off that section, and then add it, because the 220V light strip is connected in series, adding more will be dark, adding less will burn the lamp, if it is low pressure, it is the same method as soft epoxy resin glue! If it's just a silicone cover on the outside, cut it off the edge and fix it! The common problems of the light strip are the dead lamp and the resistance is broken!

Nothing is a big deal!

Yonghui lighting LED strip light, unconditional lifetime warranty. You can go to Tmall and find it.

How to solve the problem of not lighting up in the middle? Of course, I'll give you a new one.

Why is the light strip too long, after cutting off a part, the light strip will not light up.

Why is the light strip too long, after cutting off a part, the light strip will not light up "The light strip is bright because after the electricity is connected, the electric dissipation current energy ** road constitutes a cycle, which is a complete cycle. You cut off part of the strip so that the current can't pass. So it doesn't light up.

The traditional light strip can only be used normally if the sail is cut off at the pre-cut place, so there is a difference in size and even waste, resulting in a waste of resources, and there will also be a risk that some of them will not be lit.

There are two reasons for not lighting up: the first is the problem of the light strip itself, the light strip is soldered, the light is driven and it will not light up when it is moved at an angle, this is a quality problem, it is caused by virtual welding when welding the lamp beads, you can find the seller;; The second reason is that the alloy wire of the power cord pin and the light strip is not fully in contact.

The characteristics of the performance are that the light strip is on for a period and not on for a while. As long as the pin is fully inlet into the lamp wire and fully contact the alloy wire, it is OK.
