How to judge the quality of LED lighting fixtures? led lighting quality judgment guide

　　Quality judgment guide

1. Look at the packaging and identify the trademark.

China requires LED lighting manufacturers to mark the following content on the outer package: rated voltage, voltage range, rated power, rated frequency. Generally speaking, the trademark printing quality of high-quality LED products is good, the font is clear, and it is not easy to fall off, and there are trademarks and related certification marks of manufacturers. Shoddy products have poor printing quality, fuzzy font, easy to erase, and no manufacturer's trademark and related certification marks.

2. See with your eyes and cover with your hands.

The real LED energy-saving lamp, is to use three primary color tube, tube white, with the hand to cover the look, more white. In addition, from the point of view of the lamp, you can put a number of lights together to compare, the shape and size of the lamp is better for the machine bending molding, mostly large-scale production products, product consistency is good, quality is easier to ensure, the interchangeability of maintenance is better. Of course, the appearance should not have cracks, loosening and marks of prying between the interfaces. In the process of installation and disassembly, the lamp holder should not be loose or tilted.

3, look at the parameters, anti-glare.

The main parameters of LED lighting, especially high-power LED lamp beads, are luminous efficiency, color rendering index, color temperature and so on. Luminous efficiency represents the energy-saving effect of LED lighting fixtures, which must be greater than 80 LM/W to meet the requirements; The higher the color rendering index, the better the color rendering of the light source. Generally, 0.8 can be achieved, and painting operations have higher requirements for color rendering index; Color temperature will directly affect the lighting effect and human health, especially as a reading lamp or bedroom night light, it is best to use 2700K low color temperature LED lighting fixtures. If there is glare that will have a potential adverse effect on children in the home, in order to reduce glare, it is simply the same brightness, the larger the luminous area, the better.

4, look at the origin, choose the enterprise.

China's LED industry is the largest cluster in the Pearl River Delta region and southern Fujian region, the two regions concentrated a lot of excellent LED companies, a large number of products exported to foreign countries, its quality and technology is relatively mature. In addition, enterprises that choose to produce LED lamps can also be judged by whether they are registered, whether there is certification, whether there is a formal website, relevant media reports, and user feedback.

The above is how to judge the quality of led lighting guide, I believe you know how to judge the quality of a lamp after reading, we buy led lights in daily life, need to shop around, and then see how everyone's evaluation is, below to recommend Liyang Optoelectronics, quality assurance.
