Abstract:
In one embodiment, a backlight assembly comprises: a bulb having a bulb first side and a bulb second side located on a side of the bulb opposite the first side, a reflector plate disposed on the bulb first side, and a front bulb reflector disposed over the bulb second side. The front bulb reflector has a partially reflective member capable of reflecting greater than or equal to 60% of light from the bulb toward the reflector plate, and an inner surface on a reflector second side located opposite the reflector first side. The overall geometry of the front bulb reflector is concave on the reflector second side and convex on the reflector first side.
