Abstract: The light guide plate 32 has a light receiving portion 36 on one side thereof to receive light emitted by the LED 24 and a flexible light guide body 35 for transforming the light received by the light receiving portion 36 into planar light. The light guide body 35 is arranged along the liquid crystal panel 23 and has a plurality of light scattering portions 30 arranged on an outer surface thereof in a propagation direction of light emitted by the LED 24.

Abstract: A lighting effects system comprises an arrangement of lamp elements, such as light-emitting diodes (LEDs) or other light elements, on a panel or frame. The panel or frame may be relatively lightweight, and may include one or more circuit boards for direct mounting of the lamp elements. The panel or frame may have an opening through which a camera can view. A mounting bracket and assembly may be used for attaching the panel or frame to a camera. The lamp elements may be electronically controllable so as to provide differing intensity levels, collectively, individually, or in designated groups, and may be strobed, dimmed or otherwise controlled according to manually selected or programmable patterns. Different color lamp elements may be mounted on the same panel/frame, and, in particular, daylight and tungsten colored lamp elements may be mounted on the same panel/frame and their relative intensities selectively controlled by control circuitry.
