摘要： Provided is a bacteriostatic method for suppressing the proliferation of a bacterium while reducing the influence on a human body.
The bacteriostatic method is for suppressing a proliferation of a bacterium in a target region and includes a step (a) for irradiating the target region with ultraviolet light having a main peak wavelength of 200 nm to 230 nm inclusive at an average irradiance equal to or less than DMax (µW/cm2) defined by Formula (1): DMax=9391.1×exp−0.043λ
where λ is the main peak wavelength (nm),
wherein,
when the bacterium is Staphylococcus aureus, the step (a) includes irradiating the target region with the ultraviolet light at an irradiance equal to or greater than 0.4 µW/cm2, and
when the bacterium is a mold, the step (a) includes irradiating the target region with the ultraviolet light at an irradiance equal to or greater than 0.29 µW/cm2.-

摘要： An excimer lamp (2) includes a long light-emitting tube (10) transparent to ultraviolet light, a pair of electrodes (11) disposed separately along the radial direction of the light-emitting tube (10), and a reflective coating (14) formed on the inner wall surface (10b) of the light-emitting tube (10). The reflective coating (14) includes a first reflective area (14p) facing a light-emitting surface (12) that emits light toward a light irradiation target area, and a second reflective area (14q) facing a light-collecting area (13) disposed at a position different from the light-emitting surface (12).

摘要： System and method generally relate to extending a lifespan of an excimer lamp. The system 100 includes a ultra-violet (UV) light source 101 (for example, an excimer lamp) having a pair of dielectrics 104,108 configured to separate electrodes 102,110. One of the electrodes includes a metal mesh 102. The system includes a power supply 116 electrically coupled to the UV light source and configured to deliver electrical power to the UV light source. The system includes a temperature sensor 118 operably coupled to the UV light source. The temperature sensor is configured to generate a temperature signal indicative of a temperature of the UV light source. The system includes at least one processor 114. The at least one processor is configured to determine a temperature of the UV light source based on the temperature signal, and adjust the electrical power delivered to the UV light source based on the temperature signal.

摘要： An ignition facilitated electrodeless sealed high intensity illumination device is disclosed. The device is configured to receive a laser beam from a continuous wave (CW) laser light source. A sealed chamber is configured to contain an ionizable medium. The chamber has an ingress window disposed within a wall of a chamber interior surface configured to admit the laser beam into the chamber, a plasma sustaining region, and a high intensity light egress window configured to emit high intensity light from the chamber. A path of the CW laser beam from the laser light source through the ingress window to a focal region within the chamber is direct. The ingress window is configured to focus the laser beam to within a predetermined volume, and the plasma is configured to be ignited by the CW laser beam, optionally by heating of a non-electrode ignition agent located entirely within the chamber.
