Abstract
The present invention is directed towards a thin, flat glass envelope having an enclosed, internal channel and a molded edge for affixing attachments directly to the glass envelope. Suitable attachments include filters, i.e., diffusion, polarizing, glare reducing, brightness enhancing, liquid crystal display screens and masking components. The channeled envelope has a front and a back surface laminated and integrated together to form a unitary body essentially free of any sealing materials. A lightweight, light-emitting device or low-pressure discharge lamp can be formed from this channeled envelope, suitable for employment in the fields of LCD backlighting, automotive lighting, and general lighting.
