DOE rumor blue damage CREE was LED-OLED mixed patent

LED there is a blue light damage has been controversial, in order to clarify the truth, to LED name, the U.S. Department of energy DOE has previously released a demonstration of LED lighting and blue light hazard report. Recently, DOE in science and technology report True Colors once again stand.

DOE said in the report, it is well known that excessive exposure to blue light (wavelength of about 400-480nm) will cause damage to the retina, while the white light LED emission peak is usually around 450nm. But this does not mean that LED is more likely to cause visual impairment, physical and physical damage than other conventional light sources. In fact, at the same temperature (CCT), including LED source and the blue light is equal to the amount of energy consumption, and the release of LED in less than 450nm under the traditional light source, so the harm to human health caused by LED is smaller than the other light source. In addition, DOE pointed out that all over the museum have begun to use LED lighting, LED is not the most favorable evidence of damage to the goods.

CREE mixed LED and OLED technology to produce white light by the United States Patent

Recently, the United States, a manufacturer of CREE invention patent mixed LED and OLED white light technology was recognized by the U.S. patent and Trademark Office, the patent number is US8841834B2.

CREE said that the new invention is a combination of LED lighting and OLED lighting to form a white solid state lighting system. The LED and OLED were placed in the mixing chamber of the lamp in a certain interval, and the blue light emitted by LED was combined with the red light emitted by OLED to produce white light, the color rendering index was as high as 90.
