Reflector device

Claim 2

A reflector device for an elongated radiation source comprising a profiled holder formed as a body having an elongated cavity, said body having a surface defining said cavity that is shaped to partially surround said radiation source, said surface having a reentrant portion defining a longitudinally extending groove adjacent said cavity, the main axis of the cavity and the longitudinal axis of said groove being substantially parallel to each other and with the longitudinal axis of said radiation source, a radiation reflecting metal strip within said cavity, and stop members provided at edges of said body adjacent the cavity for engagement with corresponding edges of said reflecting metal strip, thereby causing said reflecting metal strip to elastically inflect against said cavity surface, said reflecting metal strip having a width which keeps said reflecting metal strip permanently flexed into the groove under elastic deformation while in a mounted position.

Claim 3

A reflector device as claimed in claim 1 further comprising a source of a cooling medium, cooling channels within said body for distributing said cooling medium, and means for passing said cooling medium over said reflecting metal strip, said means comprising openings in said reflecting metal strip at locations over the length of the cooling channels where said reflecting metal strip covers the cooling channels, and a plurality of lugs forced through the reflecting metal strip at said locations to form gill-shaped guiding members for the cooling medium emanating through the openings, said lugs being arranged and directed to guide the cooling medium to sweep along the surface of the reflecting metal strip in paths traverse to the longitudinal axis of the radiation source.

Claim 4

A reflector device as claimed in claim 1 further comprising a viscous heat conducting material between the cavity surface and the reflecting metal strip to increase the heat transfer from the reflecting metal strip to the body of the holder.

Claim 5

A reflector device as claimed in claim 1 wherein said groove and said reflecting metal strip form a channel for connection to a source of cooling medium and said body provides a plurality of parallel channels, a first channel being connected to said source of cooling medium and remaining channels being connected through transversal connections with said first channel forming a net of cooling channels.

Claim 6

A reflector device for an elongated radiation source comprising a profiled holder formed as a body having an elongated cavity, said body having a surface defining said cavity that is shaped to partially surround said elongated radiation source, said surface having a reetrant part defining a longitudinally extending groove adjacent said cavity, the main axis of the cavity and the longitudinal axis of said groove being substantially parallel to each other and with the longitudinal axis of said elongated radiation source, said profiled holder having outside longitudinal slits, the cross-section of said slits having a wider inner portion and a narrower outer portion for interconnecting with adjacent reflector devices, a radiation reflecting metal strip within said cavity, stop members integral with said body at parallel edges of said body adjacent the cavity for engagement with the parallel edges of said reflecting metal strip thereby causing said reflecting metal strip to elastically inflect against said cavity surface, said reflecting metal strip having a width to keep said reflecting metal strip permanently flexed into the groove under elastic deformation in its mounted position, a source of cooling medium, said groove and the reflector strip forming a channel for connection to said source, a plurality of parallel channels within said reflector body, one channel being connected to said source and the remaining channels being connected through transversal connections to form a net of cooling channels, said channels being shaped so that said cooling medium is supplied to opposite ends of the elongated radiation source, said reflecting metal strip provided with openings over the length of the channels at places where said strip covers the cooling channels for distributing the cooling medium over the surface of the reflecting metal strip, a plurality of lugs forced through said strip at said places to form gill-shaped guiding members with said strip for the cooling medium emanating through the openings, said lugs being arranged and directed to guide the cooling medium to sweep along the surface of the reflecting strip in paths transversal to the longitudinal axis of said radiation source, and a viscous heat conducting material between the supporting surface and the reflector strip for increasing the heat transfer from the reflector strip to the reflector body.

Claim 7

A reflector device for an elongated radiation source comprising a profiled holder formed as a body having an elongated cavity, said body having a surface defining said cavity that is shaped to partially surround said elongated radiation source, said surface having a reetrant part defining a longitudinally extending groove adjacent said cavity, the main axis of the cavity and the longitudinal axis of said groove being substantially parallel to each other and with the longitudinal axis of said elongated radiation source, said profiled holder having outside longitudinal slits, the cross-section of said slits having a wider inner portion and a narrower outer portion for interconnecting with adjacent reflector devices, a radiation reflecting metal strip within said cavity, stop members integral with said body at parallel edges of said body adjacent the cavity for engagement with the parallel edges of said reflecting metal strip thereby causing said reflecting metal strip to elastically inflect against said cavity surface, said reflecting metal strip having a width to keep said reflecting metal strip permanently flexed into the groove under elastic deformation in its mounted position, a source of cooling medium, said groove and the reflector strip forming a channel for connection to said source, a plurality of parallel channels within said reflector body, one channel being connected to said source and the remaining channels being connected through transversal connections to form a net of cooling channels, said channels being shaped so that said cooling medium is supplied to opposite ends of the elongated radiation source, said reflecting metal strip provided with openings over the length of the channels at places where said strip covers the cooling channels for distributing the cooling medium over the surface of the reflecting metal strip, a plurality of lugs forced through said strip at said places to form gill-shaped guiding members with said strip for the cooling medium emanating through the openings, said lugs being arranged and directed to guide the cooling medium to sweep along the surface of the reflecting strip in paths transversal to the longitudinal axis of said radiation source, and a viscous heat conducting material between the supporting surface and the reflector strip for increasing the heat transfer from the reflector strip to the reflector body.
