Led white spectrum
Nettet16. okt. 2024 · LED can directly emit red, yellow, blue, green, cyan, orange, purple and white light. In addition, the led light is environmentally friendly and has no harmful … NettetThe majority of white LEDs being used today are made from a blue LED pumping a longer wavelength visible phosphor. Color rendering index (CRI) is a measure of the spectral matching to sunlight. 100 is considered to be the same as sunlight and most LEDs used in general illumination today have a CRI greater than 80.

Nettet13. aug. 2024 · The LED emits ultraviolet radiation, not visible to human eye, which falls on the red, green, and blue phosphors and excites them. When these RGB phosphors gets excited, they emit radiations which are mixed together to provide a white light. This white light has a still broader wavelength spectrum than earlier discussed technologies.
