As costs continue to decline and energy efficiency continues to increase, LED mass adoption is coming, and LED lighting has become the hottest topic in the industry. Because the design involves many technologies such as optics, thermals, and microelectronics, LED designers are usually More attention is paid to the design factors of appearance, heat dissipation, and drive circuit, while neglecting the selection problem. As costs continue to decline and energy efficiency continues to increase, LED mass adoption is coming, and LED lighting has become the hottest topic in the industry. Because the design involves many technologies such as optics, thermals, and microelectronics, LED designers are usually More attention is paid to the design factors of appearance, heat dissipation, and drive circuit, while neglecting the selection problem. At the 2011 International LED Innovation Forum at the Shanghai Electronics Show in Munich, Zhou Xuejun, Marketing Director of Philips Lumileds Asia, delivered a keynote speech entitled "Support for LED Technology Development in Lighting Applications". In this speech, Zhou Xuejun combined with Philips Lumileds to share the LED The view of the key parameters of the chip is believed to be very helpful for designers. Zhou Xuejun revealed that Philips Lumileds has already approved more than 1 billion chips, and accumulated 15,000 hours of measured data, and another 700 million hours of test data accumulation, which is very valuable for LED lighting designers. experience. As LED energy efficiency continues to increase and costs continue to fall, LED chips have begun to price wars. At this time, in addition to considering cost factors, we must consider some other key parameters, such as reliability indicators. Zhou Xuejun pointed out. He believes that the three major indicators that constitute LED reliability should be: Lumen maintenance rate - no lumen maintenance rate, will cause the same batch of LED lamps to vary in brightness, so engineers should learn to look at this indicator curve. For color stability, he suggested that information can be obtained by consulting the manufacturer's LM-80 report. To examine the reliability of the supplier's supply chain - if it is not delivered in time, it will cause your order to fly away! In addition, he also pointed out that to examine the light quality of LEDs, the three elements of this light quality are Consistency, indifference, and color rendering are critical to stable and reliable LED luminaires. In addition, he revealed that there is a QR code on the back of Philips Lumileds' latest generation LUXEON3LED products. Check the QR code to get a lot of information about the chip, such as the date of manufacture, MOVCD information, etc., which also facilitates the maintenance of LED lamps. .
