Abstract

An illumination system including: light source elements including at least a first element for emitting a first color light and a second element for emitting a second color light whose color is different from the first color light; a screen cast the first and second color lights from the light source elements; and a plate which is placed between the light source elements and the screen, and comprises first areas and second areas, the first and second areas having different properties of conducting light from each other. In this system the first color light is cast through the plate on a firstspot of the screen and the second color light is cast through the plate on a second spot of the screen. Then, the first and second spots overlap with each other.

Description

technical field [0001] The invention relates to a lighting system for illuminating various equipment surfaces with colored light. Light is projected from the interior of the device onto the surface to project an image, such as emblems, symbols, logos and geometric patterns, on the surface. In particular, the lighting system is suitable for integration with portable electronic devices. Background technique [0002] Recently, some portable electronic devices, such as portable telephone terminals, PDAs (Personal Data Assistants) and wrist watches, have an illumination system for emitting various colored lights in response to predetermined actions of the device. [0003] For example, when a portable telephone terminal receives a call, or while the portable telephone terminal is establishing a connection with another telephone terminal, the lighting system of the portable telephone terminal projects a business logo on the surface of the portable telephone terminal. [0004] The...
