A few days ago, the author visited the Meicheng market and found that with the improvement of people's living standards and environmental awareness, and affected by the "China's phase-out of incandescent roadmap", energy-saving and environmentally friendly LED lights have become the new favorite of lighting products. However, in the face of LED lamps with many brands and different prices, many citizens do not know how to distinguish the quality of their products. To this end, the author specifically interviewed the relevant staff of the Municipal Quality Supervision Bureau. The author has learned that in recent years, the price of LED lamp household lamps has begun to approach the price of energy-saving lamps. From the perspective of long-term use, more and more people are willing to choose LED lamps that are both economical and environmentally friendly. The 5-watt LED lamp is equivalent to a 13-watt energy-saving lamp, equivalent to a 65-watt incandescent lamp. Chen Yongda, director of Meijia Lighting City, Jiangnan Binfang Avenue, told reporters that 5 watts of LED lights are only 15 yuan, 13 watts of energy-saving lamps are 13 yuan, while incandescent lamps consume electricity, LED lights are energy-saving and have a long life, most consumers measure After that, the LED light will be selected. Incandescent lamps are used today, usually in the corridors of rental houses and in rural pig pens. According to the staff of the Municipal Quality Supervision Bureau, the quality of LED lights is mainly based on the chips and production processes. Even with the same specifications of the LED lights, the price of different manufacturers is not the same, the price of LED lights lies in what brand of light-emitting chips, the cost of good chips must be high, and the price of LED lights is also high. The quality of LED lamps with rough appearance and material workmanship is definitely poor. When selecting LED lights, the public should pay attention to the packaging and trademarks. They should choose products with brand name or trademark R, and the trademarks, models and specifications are clear and beautiful. At the same time, to see the appearance of the LED tube, the real LED light is to use three primary color tubes, tube white, cover by hand, whiter. It is also possible to compare a plurality of lamps together. The shape and size consistency of the lamps are mostly mass-produced products, the consistency of the products is good, the quality is easily ensured, and the interchangeability during maintenance is better. In addition, it is necessary to check the temperature when the LED lamp is working. It is necessary to select a product with a lower temperature rise. It is worth mentioning that many LED lights are very dark, which is unfavorable for the life of the lamp. The LED lamp should be provided inside. Power circuit and PCB board. Finally, it should be noted that if LED bulbs, ceiling spotlights, and track spotlights are illuminated on a white wall, there should be no obvious color temperature error such as color spots and color circles. If there is such a phenomenon, the lamp bead source is inferior. Consumers should avoid buying.
