Abstract
Abstract: This paper reports a blue-free LED bulb with green light LED chip and orange and red phosphor coating on the chip. The green light LED chip has a wavelength of 525nm. The orange and red phosphors on LED chip have peak wavelength of 590nm and 620nm respectively. The green LED chip with orange and red phosphors produces blue free amber light which is more beneficial to human sleep compared to light with blue wavelength.
