Method and system for ozone generation

A method of generating ozone gas, the method comprising:

• receiving a stream of ambient air that includes gaseous oxygen;
• generating ozone gas in accordance with applying ultraviolet (UV) irradiation provided in accordance with a wavelength of 185 nanometer (nm) to at least a portion of the gaseous oxygen of the stream of ambient air, the UV irradiation provided via an optical lamp module powered by a direct current (DC) battery source, wherein the optical lamp module is disposed within a housing of an ozone generating device having an ingress port and an exhaust port;
• producing a first modified air stream during a first mode of operation in accordance with the generating;
• detecting, via one or more sensor devices, a condition external to the housing;
• switching, responsive to the detecting, to a second mode of operation that produces a second modified airstream, the second modified airstream having a higher flowrate than the first modified airstream;
• receiving the stream of ambient air via the ingress port of the housing:
• exhausting one of the first modified air stream and the second modified airstream via the exhaust port of the housing, the optical lamp module being disposed intermediate the ingress and exhaust ports;
• and
• detecting, using one or more proximity-based motion sensors, the condition external to the housing as being an absence of a person within a predetermined area around the housing;
• wherein the second modified airstream comprises at least one of:
• (i) a higher concentration of ozone gas than the first modified airstream, and (ii) a higher flowrate of the exhausting as compared with the first modified airstream.
