Yu Zhilong: Take advantage of small power LED to seize the market

At the Symposium on Cross-Strait Lighting Technology and Marketing held on November 17-18, Mr. Yu Zhilong of Shanghai William Lighting Co., Ltd. explained his traditional low-power LED and new type with his experience in the domestic and international lighting industry for more than 20 years. Power LEDs are unique insights into general illumination sources.

Mr. Yu expressed his views very humorously with his wife or the original. He believes that when it comes to the application of LED in the field of general lighting, people always think of high-power white LEDs, while ignoring low-power LEDs, and even more fundamentally negating low-power white LEDs such as 20mA, 5mm white LEDs. Applications in the field of general lighting. This conclusion is rash and will cause huge losses to society.

Mr. Yu said that the traditional 20mA, 5mm LED is the most widely used LED, and it is a very considerable resource. In addition to the advantages of long production history, mature technology, and high degree of automation in production testing, some R&D practices in recent years have proved that 20mA, 5mm LED can not only improve the performance of light-passing performance, but also be superior to high-power white LEDs, and with high-power white LEDs. Compared to 20mA, 5mm LEDs also produce higher light efficiency. Especially in low-power general-purpose lighting with a large amount of coverage, it has higher efficiency and lower cost system superiority. Moreover, with 20mA, 5mm LED has been able to produce a light bulb with a system luminous efficiency of 100 lumens per watt. Compared with high-power white LED bulbs, 20mA, 5mm LED has an absolute price/performance advantage. In general lighting applications with low illumination levels, 20 mA LED technology has significant advantages over other light sources. Comparing the direct cost per 10,000 lumens of a 20 mA, 5 mm LED, incandescent and compact fluorescent source with a luminous flux of 100 lm, the result is a 20 mA, 5 mm LED lamp that costs significantly less than incandescent and compact fluorescent lamps.

Mr. Yu also quoted IFC statistics from the international financial organization. He said that there are still nearly 2 billion people in the world who do not have electric lights. They still use less than 10 lm of oil lamps, and their annual market potential is 38 billion US dollars. Therefore, he believes that replacing the oil lamp with a 50 or 100 lm 20 mA LED can not only improve the lighting and living conditions of the above people, but also generate enormous social and economic benefits. If the shortcomings of 20mA and 5mm white LEDs are overcome, such LEDs will be widely used in the field of general illumination, especially in high-power LEDs, which cannot be compared with traditional light sources (such as fluorescent lamps, high-intensity discharge lamps, etc.). When competing, we should not miss the opportunity, give full play to the advantages of 20mA, 5mm LED technology, and seize the common LED lighting source.
