Led spotlights are one of the many lamps that many families choose when choosing lighting. After we use it for a while, we find that it is not bright. Do we know the reason? How to deal with it? Many people are considering The problem, today Xiaobian will come with everyone to see why the led spotlights are not bright and the precautions for the installation of led spotlights! I hope you can help you who are worried about the spotlights.
What are the reasons for the lack of led spotlights?
1. The whole lamp is not lit;
If there is no light, it may be that the lamp bead or the drive is broken, but under normal circumstances, the drive is broken. You can replace it directly. Remember to choose the driver. The drive is the heart of the lamp. The heart is not good. no good.
2. The light flashes and flashes;
It is very likely that the driver is broken, and it can be replaced if there are conditions. It may be that a certain lamp bead is broken. The method of judging can shorten a lamp bead to see if it is normal. If a short bead is good, it proves that the lamp bead is broken. If there is a condition, the lamp bead can be replaced. It is a high-power lamp bead that can be removed and replaced. If it is a patch lamp bead, it is more troublesome, either changing the lamp board or scrapping the entire lamp.
3. Just started to shine, not so bright after a while;
When the ceiling light flashes, the possibility of a bad drive is relatively large, and the drive is broken and replaced directly. It is also possible that a certain lamp bead is broken, and the processing method refers to the previous one.
4. The lamp is burnt;
When this happens, it can be seen that the wick of the lamp bead is blackened. The reason for this may be that the heat dissipation is not good enough, and the lamp bead burns itself. The quality of the lamp bead is unstable. Perhaps one (several) of the lamp beads are broken, resulting in a short circuit. The voltage applied to the other lamp beads is too large to burn out. There is also a power supply that is unstable and the current is too large. For the treatment method, refer to the lamp beads and power supply processing methods in the above several items. If the heat dissipation is not good, check if the lamp board and the heat sink have thermal adhesive, and the connection is intact.
How to solve the led spotlight does not shine?
1. Check the light switch and make it in the on position. Pull the wire switch to open the cover and see if the two terminals are connected. It can be seen by pulling the switch a few times. The wall switch is normally turned on when the upper end is pressed. .
2. Replace the fault tube light starter with a good starter prepared by hand. The method is to pinch the starter shell by hand, turn it counterclockwise to a certain angle, and then take it down. When the starter is installed, the rotation direction is opposite. If it is replaced by a starter, the lamp should be illuminated normally.
3. Hold the lamp tube with both hands and turn it slightly. Sometimes the starter flashes immediately and the lamp will light up. This is because the rotation makes the lamp tube and the tube holder contact.
4. Remove the other lamps that are normally used to replace the faulty lamp. If the lamp is illuminated, it can be concluded that the lamp is broken.
5, should be carried out on the dry wooden chair during maintenance, to avoid accidents such as leakage of iron lamp umbrella.
Led spotlight installation considerations
When installing led spotlights, the transformers are usually installed inside the holes, and there is no unsafe problem. Because the space in the ceiling is large, the heat dissipation is very good.
The common problem with installing spotlights is that some workers did not arrange the power cords during the previous construction, which caused the lights to be not found after the ceiling. Therefore, it is necessary to pay attention to the position of the wires. Need an electrician to work with woodworkers. Another problem is that some of the lamp holes are not accurate when excavated, resulting in inconsistencies in size or spacing, and they are awkward.
The lamp hole forms a depth due to the height of the ceiling, which depth can be placed in the spotlight. If not enough, the light cannot be installed. Therefore, it is necessary to consider what kind of spotlights to use when hanging the ceiling.
The led spotlights in the home don't light up. Don't worry, find the reason why your spotlights don't shine. It is the most crucial. The above is the reason why the small spotlights that are introduced by Xiaobian today are not bright and the precautions for the installation of led spotlights are finished here. If you want to know more information, please continue to pay attention to the decoration home.
In order to prolong the durability of glass bead and prevent its spallation from paint after extruding by vehicles, these beads are coated with a special coating during the production process to increase the adhesion between glass bead and paint, so that can prolong the durability of glass bead above 20%.(It is usually used for surface treatment of Drop on glass beads).
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
