Transforming blue into white
LED chips usually emit blue light. To deliver white light you need to add a phosphor to the LED. This phosphor absorbs blue light and shifts the light spectrum towards red. Then by mixing different phosphor materials, you can create cold or warm light.
This principle also applies to violet LED chips, not just blue chips. Violet chips emit violet light at a shorter wavelength but is still far away from emitting UV light. For violet chips, you need to add some blue emitting phosphor so the additive color mixture is working and you get the white color in the end.
The way how and in which quantity phosphors are brought into the LED binder depends on the application of the LED device.
For example, in the automotive industry, which requires exterior lighting solutions like headlamps, carmakers like to provide cold and bright light. In other areas such as indoor environments where people want to feel comfortable, warm and clear lighting is preferred – such as in stores.
