Energy-saving lamps not only consume less power, but also have a long service life. Therefore, they are widely used in home decoration, but if the energy-saving lamps you choose are inferior, they will not only affect the service life of the lamps. More importantly, it will also bring great harm to our health. So how do you tell the quality of energy-saving lamps ? Next, Xiaobian will take you to distinguish it. How to distinguish the quality of energy-saving lamps? Comparing a plurality of lamps together, the shape and size consistency of the lamps are better, and the quality of the products produced by mass production is guaranteed. At the same time, the outer casing should not be cracked or loose, and there should be no traces of the seal at the seal. During the installation and disassembly process, the lamp cap should not be loose or smashed. How to distinguish the quality of energy-saving lamps? Second, look at the quality of plastic parts The plastic casing of the energy-saving lamp must be made of flame-retardant engineering plastic. The advantages are: heat-resistant flame retardant, good electrical insulation, high hardness, good rigidity, resistance to cracking, easy printing, whitening and no discoloration. The disadvantage is that the cost is slightly more expensive. Ordinary plastics are prohibited for the production of energy-saving lamps. The counterfeit products adopt medium and low-grade plastics, and their heat resistance and flame retardancy do not meet the standard requirements. They are brittle and easy to crack, easy to turn yellow and fade, and there are potential safety hazards. How to distinguish the quality of energy-saving lamps The high-quality product adopts rare earth trichromatic phosphor coating, which has high luminous efficiency, high color rendering index, good thermal stability, light decay caused by ultraviolet light of 185 nm and long service life. A high-quality energy-saving lamp is equivalent to the use time of 3 to 8 inferior energy-saving lamps, but the price is high. The counterfeit product adopts the mixed powder coating of halogen powder or rare earth trichromatic phosphor mixed with halogen powder, which has lower luminous efficiency than rare earth trichromatic phosphor, low color rendering index, poor thermal stability, serious light decay and short life, especially Not suitable for use in thin tube fluorescent lamps. How to distinguish the quality of energy-saving lamps? See packaging and trademarks. The state mandates that the energy-saving lamp products be marked with the following contents on the outer packaging: source mark, rated voltage, voltage range, rated power, and rated frequency. Add current to the lamp, as well as other supplemental instructions related to safe use, on the lamp, on the package, or in the instruction manual. Generally speaking, the quality of the trademark printing of high-quality products is good, the font is clear, it is not easy to fall off, and it is wiped with a soft damp cloth. The mark is clear and identifiable, it is not easy to wipe off, and there are trademarks of manufacturers and related certification marks. Counterfeit products have poor printing quality, fuzzy fonts, easy to erase, no manufacturer's trademark and related certification marks.
