LED-Based Lighting

Light emitting diodes (LEDs) are the original form of semiconductor light sources and are available in a wide range of colors. They are inexpensive, rugged and long lasting. TIG is active in tracking developments in this field and has developed novel optical systems for clients that make use of LED's unique characteristics. We make use of refractive, reflective and holographic optical elements to tailor the shape of the beam and the appearance of the lamp when lit to the requirements of the application. The picture below illustrates a simulation of the ray distribution in a solid plastic optic. It produces a collimated beam with an oval intensity distribution to form the required beam pattern for a center, high mounted brake light for cars.

These optics and a variety of other designs have been designed, fabricated and tested in detail. Some have been used in demonstrations of new products or in show cars.
