The LED industry has long been looking forward to single-chip LED products with specifications above 1,000 lumens. Today, this achievement is achieved by Cree. Cree Corporation of the United States has announced that it has proven that the luminous flux of single-chip LEDs exceeds 1000 lm, which is equivalent to the luminous flux of standard household bulbs. Cree's results prove its continued leadership in LED development
When the single-chip LED is driven by 4A current, the cool white LED has a luminous flux of 1050lm and a luminous efficiency of 72 lm/W, the warm white LED has a luminous flux of 760 lm, and the luminous efficiency is 52 lm/W. Whether it is a cool white LED or a warm white LED, the light efficiency is significantly higher than that of the traditional light bulb. Looking back at Cree's product promotion history, we can see that Cree's research and development results are usually commercialized within 12 to 24 months, and the products are promoted.
John Edmond, co-founder and head of optoelectronics at Cree, said, "Cree's XLamp? LEDs are currently the best performing LED products on the market. However, unless traditional bulbs are completely replaced by LED lighting products, we will not stop developing. The pace of LED products. We have been fighting for 20 years, setting a new standard for the brightness and efficiency of lighting-grade LEDs. And we have many ways to improve this technology."
