VCC's LCS Series Litepipe® provides display panel moisture seal and 180° viewing angle. This lens and Litepipe® unit was developed to provide moisture sealing and dust control for display panels when the LED is attached to a circuit board.
Currently, the moisture sealing of a Litepipe® to a display panel requires the use of RTV-type adhesive. When applying glue for sealing, special precautions must be taken to avoid creating air gaps that would allow sealed joints to leak. Glues are not only difficult to apply but their adhesion to a lightpipe surface will change the flow of the light pattern. This also causes light leakage resulting in reduction of light emitted by the litepipe. In addition, the output surface of a lightpipe alone whether flat, concave, or convex projects little or no sidelight. This gluing method results in serious assembly problems and less than satisfactory panel displays.
