PhlatLight: Bringing More Color to TVs
By Dennis P. Barker
The focal point of a new breed of DLP HDTVs is the use of Luminus Devices’ PhlatLight technology. This innovative illumination technology is a revolutionary light source that lasts the entire lifetime of the TV (over 60,000 hours and may be has high as 100,000 hours), and delivers a consistent picture without fading, saving consumers lamp replacement costs and inconvenience over the life of the set. Needless to say, it’s setting a new standard in HDTV performance and reliability.
What is PhlatLight?
PhlatLight technology is a new type of solid state lighting source that combines the benefits of both LED (Light Emitting Diode) and laser technologies. This unique, solid state lighting technology is ideal for display and illumination applications that require high brightness and the efficient harnessing of light from a small point source. Spun out of research at MIT, Luminus’ PhlatLight technology is an efficient way to maximize light emission from an LED.
The name PhlatLight is derived from its underlying photonic lattice structures. Photonic lattices are complex arrays of sub-wavelength microstructures in a solid dielectric material that can control and radically influence the propagation of light in different directions. This new engineering discipline, combining principles of electromagnetism with the concepts of solid-state physics, has numerous applications in optics and optoelectronics. PhlatLight devices use photonic lattice patterns to extract more light out of the LED more efficiently. These sub-wavelength microstructures direct more light to the surface of the LED, they allow light to emit from the LED more efficiently, and they influence the direction in which the light is emitted. “PhlatLight has the ability to come in a wider range of LED shapes, sizes or colors and the package design allows a much wider thermal and electrical operating range than conventional LEDs, which creates LEDs many times brighter than have ever been available,” says Paul Frederickson, Marketing Manager, Luminus Devices.
