The present device provides a safe, effective means of mobile ultraviolet (UV) disinfection. A control board within the main body of the device receives data from sensors that may variously measure orientation and speed of the main body as it moves along various surfaces for disinfection. In response to such data, the control board may brighten, dim, or completely shut off UV light-emitting diodes (UVLEs), both to prevent over- and under-exposure of the materials being disinfected, and to prevent a user from unsafely using the device.

UV lamp modules for the ultraviolet irradiation of a substrate. The modules include multiple low-pressure mercury lamps, each having a longitudinal axis, located in a waterproof housing having a bottom, a top and a beam exit opening in the bottom which is closed by a beam exit window. To maintain hygiene, homogeneity and compactness, a first airflow zone for the supply of cooling air and a second, separate airflow zone for the discharge of heated cooling air are formed iii the housing. Viewed in a cross-section through the housing perpendicular to the longitudinal axes of the lamps and in a viewing direction from the bottom to the top, the beam exit window, the lamps and the airflow zones are arranged one after the other. The first airflow zone comprises an air supply duct which is equipped with at least one air-guiding mechanism for supplying cooling air to the lamps.

A UV lamp module for the ultraviolet irradiation of a substrate includes a lamp arrangement, a waterproof housing, and first and second airflow zones. The lamp arrangement includes multiple low-pressure mercury lamps each having a longitudinal axis. The waterproof housing surrounds the lamp arrangement and has a bottom side, a top side and at least two side walls connecting the bottom side and the top side to each other, and a beam exit opening on the bottom side which is closed by a beam exit window. The first airflow zone is formed in the housing and has an air supply duct with at least one air-guide for the supply of cooling air to the lamp arrangement. The second airflow zone is separated from the first airflow zone, and is formed in the housing and has an exhaust air duct for the discharge of heated cooling air. When viewed in a cross-section through the housing perpendicular to the longitudinal axes of the low-pressure mercury lamps and in a viewing direction from the bottom side to the top side, the beam exit window, the lamp arrangement and the airflow zones are arranged one after the other.

An RF fluorescent lamp, comprising a bulbous vitreous portion of the RF fluorescent lamp comprising a vitreous envelope filled with a working gas mixture, a power coupler to induce an alternating electric field within the vitreous envelope, an electronic ballast, and a mercury amalgam accommodating structure mounted within the lamp envelope and adapted to absorb power from the electric field to rapidly heat and vaporize an amalgam of mercury to rapidly illuminate the lamp envelope during a turn-on phase of the RF fluorescent lamp, wherein the structure is comprised of a substrate material coated with a mixture of indium and gold.

A mercury discharge lamp includes: a discharge tube having encapsulated therein mercury in the form of an amalgam; and a temperature control member that controls an ambient temperature of the amalgam in such a manner as to compensate for a change in the ambient temperature of the amalgam. The temperature control member may include a bimetal supporting the amalgam at a predetermined position, and the support member is formed or constituted by a bimetal. By the bimetal deforming in response to a change in the ambient temperature of the amalgam, the temperature control member changes a spaced-apart distance of the amalgam to a filament within the discharge tube and thereby changes an influence of heat generation by the filament on the amalgam. The temperature control member may include, near the amalgam, a resistance element whose resistance value changes in response to a temperature to control heat generation thereby.
