How to choose corn lamp for led lamp? How to choose LED corn lights

LED lamps with different brightness have different prices, and there is a certain gap between the prices of ordinary brightness and high-brightness LED lamps. Therefore, when customers understand, they must clearly know what kind of brightness they need, so that they can accurately position their products, so that manufacturers can give you accurate prices.

Finally, remind customers not to blindly pursue low price and low price when choosing LED lamps. Sometimes low-quality LED lamps are not as long-lived and bright as traditional lamps, which also loses the meaning of high brightness and long life of LED lamps.

1. The characteristics of the LED corn light itself: the unidirectionality of light, no light diffusion, and ensure the lighting efficiency. the
2. This LED corn lamp adopts a 360-degree light-emitting structure design, omni-directional lighting, no dead angle, E27 lamp head, and a wide range of applications. the
3. The light source efficiency of LED has reached 110-130lm/W at present, and there is still a lot of room for development, with a theoretical value of 2800m/W. The luminous efficiency of high-pressure sodium lamps increases with the increase of power. Therefore, the overall light effect of LED street lights is stronger than that of high-pressure sodium lamps.
4. The light color rendering of LED garden lights and street lights is much higher than that of high-pressure sodium lamps. The color rendering index of high-pressure sodium lamps is only about 23, while the color rendering index of LED garden lights reaches more than 75. From the perspective of visual psychology, it can achieve the same brightness. LED garden lights The average illuminance of the lamp can be reduced by more than 20% compared with the high pressure sodium lamp

First of all, we need to make sure that there is no problem with the circuit where the LED lights of our own family are located. The main problem will be the switch, which is the focus of our inspection. Check the power converter on the back of the LED light. Just remove the converter, and then use a multimeter to measure the voltage or current. If the power converter is damaged, you can buy a replacement directly, which is generally very cheap.

If there is no problem with the power converter of the LED lamp, then we can switch the multimeter to the voltage output gear, and then put it on the positive and negative poles of the corresponding LED lamp beads to see if it will light up. If it doesn’t light up, just replace it. Generally, after the above three steps, 90% of the problems of LED lights can be solved, so that our LED lights can regain their due brilliance.

Features of New Sunshine LED Covered Corn Lamp:

1. LED corn lamp with cover is an advanced LED light source lighting product, which has the characteristics of energy saving, beautiful appearance and no glare;
2. Using high-grade PMMA village material, the light transmittance is as high as 90%, the light is bright and soft, durable and not faded;
3. Compared with the traditional fluorescent light source, the LED corn lamp can save energy by more than 40%; it has a long life span of more than 50,000 hours;
4. No ultraviolet UV and infrared IR radiation and overheating, no need for protection;
5. Intelligent remote control (optional), can adjust the light brightness by itself, convenient and fast;
6. Small power, high luminous efficiency, convenient assembly and maintenance-free.

The corn led is equal to the lampshade first, turn off the switch, and with the help of a folding ladder, remove the shell of the LED ceiling lamp, and check whether the lamp tube appears black and dark. If there is, it is likely that the lamp tube has been damaged. It must be replaced. This kind of LED light tube can be bought in the hardware store. It is recommended to choose a well-known brand.

First remove the lampshade, remove the fixing screws, or use a straight hand to hold the lampshade firmly, so as not to drop the lampshade and break it, then slowly turn the lampshade counterclockwise, so that it can be removed.

Secondly, if the lamp tube is still in good condition, you should try to tighten the lamp tube joint to see if there is any poor contact. This situation is relatively simple to operate and is also easy to happen.
