An elongated microwave powered lamp () having one or more bulbs with any length or shape or disposition according to a linear series, straight or curved, includes: at least one transparent elongated bulb () containing, in an inner space thereof, a material apt to be excited by microwave irradiation thereby emitting an electromagnetic radiation; a coaxial microwave antenna placed outside the bulb () and respectively connected to a microwave source () via corresponding antenna lead (), said bulb () and said at least one microwave coaxial antenna being displaced in a close relationship to each other to allow the microwave excitation of said material, wherein the outer tubular conductor of the coaxial antenna () has spaced holes () formed therethrough and facing the bulb (), at which microwaves are released toward the bulb.

Extended microwave powered lamp

An elongated light source envelope is disclosed. The elongated light source comprises an inner wall and an outer wall formed around a longitudinal axis. The inner wall and the outer wall may be connected at a first axial end by a first side wall and a second axial end by a second side wall. The inner wall, outer wall, the first side wall, and the second side wall define an enclosed space internal to the envelope. The light source envelope further comprises one or more walls formed between the inner wall and the outer wall to further form at least a first enclosed region and a second enclosed region within the enclosed space. The first enclosed region may be configured to emit a different spectrum of ultraviolet radiation from the second enclosed region in response to excitation of the first enclosed region and the second enclosed region by microwave radiation.

Multi-spectral electrodeless ultraviolet light source, lamp module, and lamp system

A UV lamp includes a UV lamp unit including a tubular bulb and an antenna inserted in the tubular bulb, and an antenna lead for supplying microwave energy from a microwave energy source to the UV lamp unit. The antenna lead includes a bent portion, one end of which is connected to the antenna and the other end is connectable to the microwave energy source.

UV lamp and a cavity-less UV lamp system

A structure of calorimeter provides a calorimetric head () comprising a calorimetric cell () suitable for receiving a sample holding container () containing a sample () to examine. The cell () is arranged according to a first shield (), or active shield. Outside the active shield () a second shield (), or dynamical shield is present, which comprises a cylindrical hollow body arranged around the active shield () for all its length in order to provide a space () of determined size. Outside the active shield a thermal bath is present (not shown) at a temperature lower than the first and the second shield (). The dynamic shield () allows an effective adjustment of the heat flux through the active shield () during calorimetric measures by limiting the heat flux same. In fact, in operative conditions the dynamic shield acts as thermal flywheel and keeps constant the heat flux coming from the active shield (). More in detail, the presence of the dynamic shield () ensures the reduction of the temperature gradient on the active shield () and then on the cell () containing the sample (). Furthermore, by keeping the dynamic shield () at a suitable temperature difference from the active shield (), the temperature can be controlled with much less electric power than it would be necessary if the active shield () exchanged heat directly with the thermal bath.
