Benefits of technology
The invention is a safe UV-C sterilizing bulb for use in continuous public places. It uses advanced technology to kill harmful pathogens without harming human cells. The device is efficient, affordable, and can monitor its own conditions. The inventive device uses a special filter that blocks all harmful light but allows beneficial light to pass through. The filter is deposited directly onto the bulb's envelope to avoid contamination. The device is also smart and can monitor its own life and alert users when filters need replacement or if the intensity is not up to specification. The fixture includes a multicolored LED indicator for quick visual inspection. Overall, the invention provides a reliable and safe tool for protecting public places from harmful pathogens.
Problems solved by technology
Ushio has products that filter starting at 237 nm but this risks allowing too much harmful radiation to get through.
This inventive bulb does need a higher arc voltage but that is a small challenge for all of the benefits that a quartz only envelope solution provides.

Abstract
A can type fixture including a housing adapted for insertion into a hole in a ceiling. An excimer bulb or plurality of excimer bulbs supported in the housing and adapted for emitting Far UV C radiation at a plurality of wavelengths. A filter or a plurality of filters adapted for removing Far UV C wavelengths harmful to humans. A reflector and / or a diffusion layer. A driver / power supply is supported by the housing. The driver / power supply is adapted for providing electrical power to the excimer bulb(s) and is in electrical communication with the excimer bulb(s). The driver / power supply may be adapted to dim the excimer bulb(s). An illumination element, such as an LED array may be supported in the housing. The fixture may also include a motion sensor, crowd density sensor, proximity sensor, and / or distance sensor and may communicate via IoT.
