Several Key Parameters of LED Chip Selection Must be Noted

Energy efficiency rising costs continue to decline with the led,, LED Lighting massive popularity of the era is coming, LED lighting has become the hottest industry topics, LED lighting design involves optical, thermal, microelectronics technology, so LED designers usually more concerned about the appearance of the lighting, cooling, drive circuit design factors, to the neglect of the problem of the selection of the LED chip.

2011 Munich Shanghai Electronics Show LED Innovation Forum, the Philips Lumileds Asia marketing director Zhou Xuejun published a paper entitled "to support the development of LED technology in lighting applications keynote to combine Philips Lumileds LED products, in this speech, Zhou Xuejun share views on the key parameters of the LED chip, it is very helpful for LED lighting designers.

Zhou Xuejun revealed that currently PhilipsLumileds batch shipped over one billion of high power LED chips, and accumulated 15,000 hours of measured data, in addition to 700 million hours of test data accumulated, these accumulated for LED lighting designers are very valuable experience.

"With the LED energy efficiency and rising costs continue to decline, LED chip price war has begun, At this time, in addition to cost considerations in the selection of the time, but also to give more consideration to some of the other key parameters, such as reliability indicators." Zhou Xuejun pointed out.

He considered to constitute LED reliability of the three indicators should be:
1. Lumen maintenance rate - no lumen maintenance, will lead to the same batch of LED lamps brightness varies, so engineers have to learn to look at this index curve.
2. Color stability, he prompts can be obtained by access to vendors LM-80 reports the relevant information.

To examine the reliability of the supply chain of suppliers - if not timely delivery, will result in orders to fly out of your hand!

In addition, he also pointed out to examine the quality of the LED light, the three elements of the light quality is consistency, no difference in color, which is essential for reliable LED lamps.
In addition, he revealed that the back has a two-dimensional code in PhilipsLumileds most new generation LUXEON3LED of products, access to the two-dimensional code, the chip can get a lot of information, such as date of manufacture, MOVCD information, which also facilitates the maintenance of the LED lamps.

Use Money to Open the Energy-saving LED Desk Lamp

Forget the lights may appear often, but forgot to take the money I believe few people will appear, while the non-renewable energy sources is more important than money, coins designed by the Finnish designer Timo Niskanen start lights of the the people coin of behavior and impact, projected to the lamp switch. The overall simple linear lamp design, light switches become creative action. LED desk lamp is no longer using the switch button, but the coins inserted lampholder gap lights, when the coin is removed, the LED lights will be extinguished. Work table lamp is suitable for use in public places, the library, the station, the user is encouraged to remember to turn off the lights when you leave the desk. LED energy-saving lamps is not only healthy eye, the most important thing is that the energy saving can also save money. LED desk lamp and LED lighting House introduced the piggy bank, remind us to conserve energy and turning off lights.
