Optical signal indicator with multiple light sources

摘要

The light source is in the form of a panel Ä1Ü that has a matrix of light emitting diodes Ä2Ü. The panel is plugged Ä6Ü onto a power supply Ä7Ü . The light output is directed onto a condensing disc and then onto a disc Ä5Ü that is formed with a multiplicity of lens elements . This produces a uniform lighting over a plane ÄXYÜ.
