ABSTRACT:
A housing having a generally rectangular cross section includes apertured front and lower portions which are respectively adapted to receive a liquid crystal display (LCD) and a plurality of light emitting diodes (LEDs) and which are oriented so as to face generally transversely relative to one another. Disposed within the housing between its front and lower portions are facing convex and concave inner walls which form a light channel between the LEDs and LCDs. With the LCDs and LEDs respectively positioned within the apertured front and lower portions of the housing and mounted thereto, the facing inner walls of the housing direct light from the LEDs onto the aft, inner surface of the LCDs in a diffuse, uniform manner which provides backlighting for the LCDs and prevents direct viewing of the LEDs from in front of the LCDs thus eliminating LED hot spots. The housing is comprised of two plastic sections adapted for secure snap-acting engagement and is provided with a semi-rough interior surface for diffuse reflection of the LED-emitted light.
