Linear Light Diffusing Structure for Document Scanners |
摘要 |
A tubular structure with an opening defined thereon and having an inner surface and an outer surface. The tubular structure being substantially circular in shape and is made of a highly thermal conductive material. A plurality of light sources mounted on the inner surface of the tubular structure. The inner surface is coated with a diffused white coating. Light emitted from the plurality of light sources is reflected from the inner surface before exiting the tubular structure from the opening. This structure ensures emitting a uniform diffused light and prevents non-uniform illumination when disposed in an imaging forming device.
