Tunable White

This is the ability to dynamically control the colour temperature in the white light spectrum using high power LEDs. The Tunable White function opens up a new world of design creativity, enabling innovative, contemporary lighting solutions.
Variable colour temperature adjustment
The use of changeable colour temperatures is particularly suitable for lighting in retail and domestic applications. It allows users to create mood lighting portraying warmth or coolness on demand.
Automated, tunable colour temperature
Simulated daylight can be provided in rooms without windows, to create a sense of well-being. Simulated daylight will also improve work efficiency. This simulated daylight effect is created by the automatic control of colour temperature over the course of the day and night, following the Planckian curve.
Harmonisation of several light sources
Tunable white solutions are ideal for harmonising the light temperature of several light sources, by compensating for colour temperature differences and lamp-ageing effects. Applications include sophisticated interior lighting systems and architectural lighting projects.
Customised solutions
MENTOR produces customised LED-based Tunable White solutions, tailored to suit individual requirements. This means that customers can use this innovative, emerging technology without the need of specialised knowledge. MENTOR’s Tunable White solutions achieve CRI values between 86 and 91 in the colour temperature range of 2500 to 9900 Kelvin. This results in maximum colour rendering quality, making MENTOR’s solutions ideal for the most demanding of applications.

Tunable White PREMIUM

  • Tunable white application concept with blue/mint/amber LEDs as a premium version with very good colour location precision.
  • Possible colour locations between 2500°K and 6500°K. The colour locations lie exactly on Planck’s curve.
  • Colour rendition index (CRI) greater than 90 in the range from 2500°K to 6500°K.
  • Brightness dimming from 100% down to 10%.
  • Through intelligent control, together with a colour sensor, the following advantages are possible:
    • No appearance of ageing of the LEDs over an operating period of 25,000 hours.
    • LED binning is obsolete.
    • Temperature behaviour of the LEDs has no influence on the colour location.
    • Each light engine emits the same light.
  • Modular design enables adaptations according to the customer’s wishes with regard to the communication module (e.g. Bluetooth, Dali, ZigBee, etc.), the driver output and the housing.
  • The basic functions of the light engine can be operated via an app.
  • The visual design guarantees perfectly mixed light directly at the light outlet of the housing.
