Abstract
First and second parts of an optical component may be spatially separated and not electrically connected. A passive side may contain an optical element. An active side may contain a light-emitting device. To detect damage to the optical element, passive side circuitry that is associated with the optical element may monitor a fail-safe resistor on the optical element for changes in resistance. The circuitry may use a passive side near-field communications antenna to transmit information such as information on the fail-safe resistor to active side circuitry that is associated with the light-emitting device using near-field communications. The active side circuitry can receive the transmitted information using an active side near-field communications antenna and can adjust the light-emitting device accordingly. The active side circuitry can also monitor the active side near-field communications antenna to detect when the passive side and active side antennas have been moved apart.
