The so-called big brand led tube quality makes people worry
A good LED tube must first have the following conditions. The LED lamp bead should be good. If the heat dissipation profile is aluminum, the power quality must be constant current, safety issues, good assembly technology, and no leakage. Let’s talk about
LED lamp tubes are made up of countless LED lamp beads, which are formed in the form of dots and lines. The price of different quality lamp beads is several times different, and the service life is different. High-quality lamp beads, made of gold wire For the conductor, the poor quality lamp bead should choose copper wire or silver wire. Ordinary poor quality lamp beads, the silver wire is small, the heat conduction is slow, and the heat can not be guaranteed to be emitted to the outside. On the chip, the temperature rises, the life of the chip is greatly reduced, which greatly reduces the life of the product. Aluminum profile is the best and most direct heat dissipation method for LED lamp tube. Due to the intrinsic thermal conductivity of aluminum profile, the heat in the LED lamp bead can be effectively conducted through the air convection in the space. There are three heat dissipation ways for LED fluorescent tubes: conduction, radiation and convection. The author recently took a look at the LED tube, integrated T5 tube, at the IKEA supermarket in Nanshan District, Shenzhen. The brands are Philips, Sanxiong Aurora, and Op Lighting. I found a common problem. All the integrated brackets are made of plastic brackets. I don’t know how to dissipate heat. The lamp beads of some light boards are actually attached to the fiberglass board. Such low-end LED tubes dare to set up counters in large supermarkets to cheat. Consumers, how do supermarkets check? It's really worrying. The quality of the LED tube depends largely on the power supply, and whether it is energy-saving requires a high-efficiency power supply. A high-efficiency power supply can convert as much electrical energy as possible into light energy, reduce heat generation, and indirectly increase the life of the LED tube. However, the power supply is divided into two types: isolated power supply and non-isolated power supply: although the safety performance of isolated power supply is higher than that of non-isolated power supply, it is larger in size and lower in efficiency. The non-isolated power supply is small in size, easy to install, and has a price advantage. It is more popular with everyone. Manufacturers who focus on price, in order to save costs and lower the bottom price, ignore the safety of the product, and the insulation treatment is not enough during production, and the user will often feel electric shock after using it for a period of time. So do a good job of dealing with it. Don't do it. Because of the difference of a few dollars, make and buy a low-quality product.
