Intematix phosphor opens doors for LED lighting

Phosphor, which is used in LED light fixtures, gets a redesign: Intematix introduces a separate phosphor component to improve LED efficiency and allow for more light fixture shapes.

Intematix has developed a separate phosphor for LED lights, designed to improve efficient and give light fixture makers more design flexibility.

Intematix today announced an component designed to improve LED lighting efficiency and give light fixture manufacturers more flexibility in adjusting light qualities.

The Fremont, Calif.-based company announced its ChromaLit product line, which offers a separate phosphor component that converts the blue light of LED light sources into pleasing white light.

Phosphors, which are compounds with inherent luminescence, are used for all LED light fixtures and bulbs. They are generally in a powder form that is directly coated onto LED light sources, which are semiconductors that emit light when electricity is passed through them.

By contrast, ChromaLit is a separate, disk-shaped component. According to Intematix, this allows for LED light fixtures with more possible shapes, including three-dimensional and curved LED light fixtures.

A separate phosphor component is also up to 30 percent more energy efficient, and manufacturers can swap in various phosphor components on the same LED light source to create products with a different color temperature and color rendering index.

Having a separate phosphor component can extend the life and performance of LEDs, Intematix CEO Mark Swoboda told Scientific American. That's because phosphor coating on an LED light source often reflects much of the light back toward the semiconductor light source. By contrast, a layered design means that reflected light can still be emitted around the sides of the phosphor component.

The company is targeting ChromaLit at LED light fixture manufacturers in both the commercial and residential markets.
