White LEDs

White LEDs are one of the main sources of light for most lighting applications. They are essentially a blue LED where the chip is coated in a phosphor layer to produce a white light output. White LEDs are available in a range of colour tones which is described as Correlated Colour Temperature (CCT) and is given in Kelvin (K), for example, 4000K. These colours are often referred to as "Warm White", "Neutral White" and "Cool White", depending on the bluish or orange tinge to the light. The lower the CCT value, the warmer the white and, the higher the CCT, the bluer the light appears.

White LEDs come in many different brightness levels and viewing angles. Multiple LEDs can be mounted together to produce a bright light output. They are available in both through-hole (THT) and surface mounted (SMD) packages.

Where are White LEDs Used?

White LEDs are popular in general lighting in bulbs and LED strip lights. They are also used in displays, automotive lighting and smartphones. LEDs are a popular choice over traditional lighting, such as CFL and incandescent lights, as they are an energy-saving and long-lasting light source.
