The advantages of energy-saving, long life, environmental protection and non-radiation of LED lamps make more and more people choose LED products when they buy lamps, and the application of LED lamps also penetrates into various fields. But at present, the LED market is not completely sophisticated, and the quality of products in the world is uneven. As a smart consumer, how to choose high-quality LED lighting?

Packaging and trademark.

The state requires manufacturers of LED lamps to mark the following contents on the product packaging: rated voltage, voltage scale, rated power and rated frequency. Generally speaking, the trademark printing quality of high-quality products is good, the logo is clear and identifiable, it is not easy to wipe with soft wet cloth, and the manufacturer's trademark and related certification marks are also available. When choosing product brands, firms with a certain reputation and registered capital of more than 50 million should be selected. LED beads manufacturer production standards are different, production process, staff operation is different, the production of LED beads will be significantly different from the clouds and mud.

Second, the appearance of the lamp tube.

Appearance should be free of cracks, loosening and prizing marks between interfaces. In the process of installation and disassembly, the lamp head should not be loosened or crooked. It is necessary to choose the engineering plastic flame retardant type for the plastic shell of the lamp, which is characterized by its appearance having a texture similar to that of ground glass. Generally, plastics are lubricated and glossy in appearance, but they are easily deformed and flammable. It is forbidden to be used in the production of energy-saving lamps.

3. Operation status.

Under normal working conditions, the temperature rise of LED lamps should be relatively low. If the heat dissipation condition is not good and the lamp beads work at high temperature, the light decay will be very large, and the lamp life will be greatly reduced. At the same time, if there is a quick flicker when the lamp is on and off, it also indicates that there is a quality problem.
