LED lamps have a series of advantages such as obvious power saving effect, long service life, no radiation, no stroboscopic effect, no noise, soft light, wide working voltage range, etc., and are more and more popular among consumers. How to choose a satisfactory product in the dazzling array of LED lamps? Wang Weihong, deputy section chief of the Mechanical and Electrical Department of Jiangsu Zhangjiagang Inspection and Quarantine Bureau, advises everyone:

The first trick: the brand is the key

The chip is the core component of the LED lamp, which determines the energy-saving performance and longevity of the product. At present, internationally renowned chip brands such as Nichia, Corey, and Preh are more secure in quality, and are the chip suppliers of choice for large-scale lighting companies at home and abroad.

The second measure: attach importance to design and production process

When the LED lamp is lit for a period of time, the brightness will decrease. The terminology is called light decay. The appearance of light decay, in addition to the quality of the chip, is closely related to the heat dissipation design of the lamp and the overall packaging process. At present, some companies with strong technical strength have effectively reduced the light decay of LED lights through good design. It is best to choose big brand products when purchasing.

The third measure: don't ignore "light health"

Modern people's life is inseparable from lighting, but after a long time of light, many people will develop physical discomfort, such as suffering from light fatigue syndrome, dry eyes, acid, dizziness, headache and so on. LED lights are absolutely mercury-free light sources, which not only reduce environmental pollution, but also avoid stroboscopic problems, so they are healthier. At present, many large-scale lighting companies at home and abroad are highly responsible for society and consumers, and advocate “light health”. Consumers can make screenings when they purchase.
