Yu Zhilong: play the advantages of small power LED to seize the general lighting market

In the November 17-18 meeting of the cross-strait lighting technology and marketing seminar, Shanghai William Lighting Electrical Appliance Co. Ltd. Mr. Yu Zhilong to experience in the lighting industry for more than 20 years on the traditional small power LED and a new type of high power LED lighting as a general insights.

Mr. Yu is very humorous with the wife or the original good "to express his views. He believes that the mention of LED application in the field of general lighting, always high power white LED people think, while ignoring the small power LED, even to fundamentally deny applications such as 20mA, 5mm LED these small white power white LED in the field of general lighting. This conclusion is rash and will cause great damage to the society.

Yu said that the traditional 20mA, 5mm LED is currently the most widely used LED, is a very considerable resource. In addition to the production of long history, mature technology, production and detection of high degree of automation, in recent years, some research proved that 20mA 5mm LED not only can improve the performance of luminous flux to or even surpass the match with the high power white LED, and compared with the high power white LED 20mA, 5mm LED can produce higher light efficiency. Especially in the wide range of low power general lighting, the system has the advantages of high efficiency and low cost. And now with 20mA, 5mm LED has been able to produce a system of light efficiency of 100 lumens per watt bulb, compared with high-power white LED bulbs, 20mA, 5mm LED has an absolute cost advantage. Compared with other light sources, 20mA LED technology has obvious advantages compared with other light sources in general lighting occasions. The luminous flux of 100lm 20mA, 5mm LED lights, incandescent and compact fluorescent lamp light source of the direct costs per million lumen hour for comparison, the result is 20mA, 5mm LED lamp costs significantly lower than incandescent and compact fluorescent lamps.

Mr. Yu also cited the international financial organization IFC statistics, he said that there are nearly 2 billion people in the world there is no light, but also the use of less than 10lm of the oil lamp, the annual market potential of $38 billion. Therefore, he believes that, such as the use of 50 or 100lm 20mA LED instead of oil lamps, not only can improve the lighting and living conditions of the population, but also will have enormous social and economic benefits. If the 20mA overcomes the shortcomings of 5mm, white LED, the LED will be widely used in the field of general lighting, especially in high-power LED luminous efficiency is not with the traditional light source (such as fluorescent lamps, high intensity discharge lamp etc.) match, we should not miss the opportunity, give full play to 20mA. 5mm LED technology, LED general lighting market to seize.
