Tunable White

What is Tunable White?

By combining Nichia's phosphor and LED expertise and technology, Nichia's 2-in-1 Tunable White LED has been developed to emit and control the two color temperatures out of an LED's single light emitting surface. This innovative structure allows for significant efficiency improvements and/or aesthetic improvements as designs can now be optimized both optically and mechanically with smaller systems and fixtures.

Features of Tunable White and expected use

■ Possible to design thin lighting fixtures

Uniform light emission can be achieved even at short optical distances, enabling more compact and thinner fixtures.

■ Improves the light-extraction efficiency

The distance between the LED and the diffuser can be shortened and the diffuser can be made thinner leading to improved light-extraction efficiency.

■ Simplifies the board design

Nichia's Tunable White LED allows for a simpler board design vs. the conventional method that doubled the LED count, alternating the different color temperatures.

■ Additional benefits

Example 1: When redecorating a store, it is possible to change the color temperature without replacing the fixtures and create a completely new atmosphere.

Example 2: Once a manufacturer receives orders for a lighting fixture, it is possible to easily match the color temperature and ship what is needed. This greatly reduces the inventory burden for LEDs and lighting fixtures.
