Color Temperature Change

Since LEDs are available in a series of colors that cross the spectrum of white, there is a high degree of variation of color temperatures in lamps. This can make it difficult for consumers to blend new LED bulbs with existing lighting and can increase complexity of inventory management for professionals.

Rambus’ color temperature change (CTC) LED lamps can adjust from warm to neutral to cool with the simple turn of a dial – illuminating every application in its best light. This innovative technology cost effectively enables in-lamp color temperature change through the use of a remote phosphor and a color mixing light guide, without requiring additional LEDs or expensive multi-channel drivers.

Commercial Benefits

  • Best price-performance
  • Simplified SKU management
  • Flexible and scalable to meet changing needs

Consumer Benefits

  • Always achieve the look you want
  • Tunable to match existing bulbs
  • On-bulb dial for simple adjustment

What is Color Temperature Change Technology?

Color Temperature Change example

Rambus CTC technology uses a remote phosphor and a rotating color mixing light guide to continuously adjust the light output of the lamp from 5000 kelvin (K) to 3000K and all points in between. By turning a dial that controls the coverage amount of the remote phosphor, a user can control the amount of blue light emitted by the LEDs that is converted to amber, shifting the color temperature of the lamp. This technique enables the lamp to track along the black body curve and maintain a pure color temperature and high quality of light.

Who Benefits?

Consumers, store owners, distributors and facility managers alike benefit from the simple, cost-effective and flexible color temperate change technology that is integrated directly into the lamp. The Rambus in-lamp color adjustment technology allows the end user to continuously adjust color temperature to create the desired environment, from cool white of 5,000 kelvin to warm white of 3,000 kelvin, and all points in between. In the commercial sector, this technology enables simplified SKU management and is scalable to meet changing needs. Retailers need only one bulb on the store shelf to cover all the different color options that consumers require.
