D-Light

The lighting industry is experiencing a shift in technology aimed at more energy efficient light sources such as LEDs, which in recent years have gained a significant market breakthrough. However, at high levels of brightness the efficiency of LEDs decrease. This is the problem that the project D-Light aims to solve by using diode laser technology. This has the potential to be more efficient than LEDs when making large amounts of light.

Laser-based lighting can be seen as a development of LED technology, where the same materials are used to produce photons from electricity. Here, a laser emits a thin concentrated beam of light. The goal of the project D-Light is to create energy efficiency, as well as lighting precision and quality.

The project will demonstrate the new technology under real conditions in a municipality where prototype lampposts will be developed, with lasers as the light source. For this goal we will work with:

  • diode lasers as the light source
  • phosphor material for converting the laser light into white light
  • the design and production of lighting fixtures, which optimally utilizes light
  • a survey of the quality of light and how light is perceived by users.

D-Light will be instrumental in moving the production of light sources back to Denmark and providing the market with new opportunities for lighting precision and efficiency.
