A lens for an LED having a lens body providing total internal reflection of light emitted by the LED from a first emission point disposed proximate a first junction of the lens body and centerplane. The lens includes an arcuate light-diffusing edge for diffusing light emitted by the LED and reflected by the angular base and sidewall assembly, the light being diffused by the lens at substantially uniform luminance across a sector of at least 150 degrees centered and measured about the first junction. The light diffused by the lens provides for substantially uniform mixing of at least two different colors of light emitted by a multi-color LED apparatus disposed at the first emission point.

Uniform luminance and color mixing lens for LED device

A high-isolation call cord switch includes connectivity for a standard hospital-style push-button call cord while using low voltage alternating current to isolate detection circuitry from static electricity. An alternating current signal is used to permit transformer coupling, with its intrinsic isolation capability, between the call cord switch and the detection circuit.
