A system includes multiple devices configured to emit and detect germicidal radiation. Each of the multiple devices operates in emitting mode when connected to a drive source in a forward bias configuration and operates in detecting mode when disconnected from the drive source or when connected to the drive source in a reverse bias configuration. Cycling circuitry generates a sequence of control signals that control switching circuitry to change the connections of the devices to the drive source in a cycle in which one or more of the multiple devices are switched to detecting mode and senses radiation emitted by one or more of the multiple devices simultaneously operating in emitting mode. Each device operating in detecting mode generates a signal in response to the sensed radiation. Detection circuitry detects signals of the devices operating in detecting mode and generates a detection output in response to the detected signals.

Solid state light device

An electronic circuit structure having a reduced size includes a circuit substrate, an aperture extending through the circuit substrate, and an electronic component suspended within the aperture. The suspension of the electronic component within the aperture significantly reduces the profile of the overall electronic circuit structure. The aperture further enables electronic components to be mounted in a partially overlapping fashion to reduce the surface area of the electronic circuit structure. The electronic circuit structure can make use of standard FR-4, G-10, or ceramic circuit substrates or multilayer flex circuits, as well as electronic components in the form of standard leaded integrated circuit packages. The mounting of the electronic component within the aperture of the circuit substrate provides an advantage of assisting in heat dissipation. The incorporation of mesh-like voltage and ground planes can further aid in heat dissipation and provide electrical isolation and capacitive filtering. In addition, the electronic circuit structure facilitates high density packaging of several electronic structures, for example, in a stacked or radial configuration.
