UH Researchers’ New Prototype LED Light Bulb Emits Less of That Troublesome Blue Light
June 30, 2021
LED lightbulbs offer considerable advantages over other types of lighting. Being more efficient, they require much less electricity to operate. Though LED bulbs are great, they aren’t 100% problem free. A complaint that some people have are the amount of blue light they emit.
A University of Houston research team led by Jakoah Brgoch, associate professor of chemistry in the College of Natural Sciences and Mathematics, is developing an LED bulb that emits most of its energy from the safer violet segment of the visible light spectrum.
Instead of just masking the blue light, they are developing a unique class of luminescent materials called phosphors that absorb a violet LED’s single-color emission and convert the light to cover most of the visible spectrum.
