Membrane-keypad fiber-optic backlight unit
Lumitex

Lumitex uses sheets of UniGlo Fiber Optic Cloth cut into specific sizes and shapes to create a thin flexible lighting layer that goes between the overlay and the dome switches. The product is typically 0.013" (0.33mm) thick and anywhere from 1 sq inch to over 100 sq inches.

The optical fibers coming off one end of the panel are bundled into a circular ferrule and coupled to one or more LED light sources.

Lumitex Fiber Optic Membrane Switch backlighting provides long life, low power, inert, maintenance free backlighting for all membrane switch, overlay, label, keypad and keyboard designs.

Longer Life - Durable fiber optic panel never needs replacement. Remote light source offers 20,000 to 100,000 hours life and easy replacement.

Lower Power - Sources require less power than EL, or LED Array and no inverter. As low as 5-20mA at 2-4vdc

Compact Size - Panels are thin and sources are smaller than EL inverters.
