Analysis of comprehensive performance evaluation system for LED lamps

In recent years, the LED industry has developed rapidly, but with the rapid development process, the industry has also shown a mixed situation. Taking indoor lighting products as an example, at present, most manufacturers pay too much attention to the compression of cost and ignore the quality of products. Low-end products are in any aspect of lamp efficiency, service life and light quality, even compared with traditional energy-saving lamps of medium quality, there is no advantage at all, which really does not reflect any technical advantages and values of LED. With the popularization and promotion of LED, more and more people realize that it is better to use traditional energy-saving lamps than to use low-quality LED lamps. For example, a large number of low-quality LED lamps in the market have no price advantage compared with domestic NVC, opal and other brands of energy-saving lamps, and their service life and efficiency are not comparable to these energy-saving lamps, and their existence value is very small! If the above problems are not correctly recognized and adjusted, and the low-end LED products are allowed to flow into the market, China will become the world's leading producer of LED waste! Any LED industry practitioner has the obligation to continue the phenomenon of resistance! Here, we provide the 'comprehensive performance evaluation system of LED lamps' for LED bulb lamps. The system refers to the relevant standards of China's CQC certification and the US Energy Star certification standards, on the one hand, it can enable more professional or non-professional people to have a more intuitive understanding of the comprehensive performance of LED lamps in front of you, and even give a quantitative evaluation of the comprehensive performance of lamps, instead of being fooled by ultra-low prices; Secondly, through this article, we also call on relevant departments to draw up relevant standards and regulations as soon as possible, and through similar comprehensive performance evaluation system of lamps, for all LED lamp products that have obtained relevant certification certificates, give intuitive and quantitative evaluation. The following illustrates the necessity and value of 'LED lamp comprehensive performance evaluation system' through actual cases. The three LED bulb lamps in the figure below are Philips Prince Series 12 W- 800LM bulb lamp, Fujian Wanbang photoelectric MCOB mode 9 W- 810LM bulb lamp, NVC Lighting remote excitation mode large angle 500LM bulb lamp, three products are from domestic and foreign LED lighting industry giant enterprises, have many institutions to give recognition and honor, the design details of the product are the model for most LED practitioners to learn. Here, we temporarily put aside the cost and sales price of lamps and lanterns, and separately compare the comprehensive performance indexes of products. According to the current relevant standards, it is difficult to distinguish Bo Zhong, each product has its own advantages in terms of service life, luminous efficiency, color development, luminous angle, and luminous maintenance rate. For example, the nominal life of Philips products is 50 thousand hours; Although Wanbang bulb has a nominal life of 40 thousand hours, it has attracted wide attention in the industry due to its high luminous efficiency.
