Nettet23. jan. 2024 · The first visible-spectrum LED light was developed in 1962 by Nick Holonyak, Jr., an engineer at General Electric attempting to build a laser. It was red, the result of mixing gallium arsenide with gallium phosphide. Colleagues at GE dubbed it “the magic one” and within a few years, it was followed by red-orange, orange and yellow … NettetCCT between 4000K and 6500K has been the choice for many countries that have recently retrofitted their street lighting from HPS to LED. However, 29% of the spectrum of 4000K LED lighting is emitted as blue light, which the human eye perceives as a harsh white color. Apart from its impact on drivers, blue-rich LED street lights operate at a ...
