Reflektor. Reflector.
Oppfinnelsen angår en reflektor for en langstrakt strålingskilde som er anordnet i en profilert holder, med en refleksjonsflate hvis hovedakse er hovedsakelig parallell med strålingskildens akse, hvor holderen er formet som et legeme, med en bæreflate for en strålingsreflekterende metallstrimmel og med parallelle kanter som er forsynt med stoppeorganer som hver kommer til anlegg med en av-refleksjonsstrimmelens parallelle kanter som er fjærende presset mot bæreflaten, hvor bæreflaten er forsynt med minst ett spor som er anordnet bak strålingskilden og hvis lengderetning hovedsakelig er parallell med hovedaksen, og hvor strimmelmaterialet har en slik \b'feddé 'at' i:'montert stilling fastholdes strimmelen mellom stoppeorganene og er permanent innbøyet i sporet under elastisk deformering.. The invention relates to a reflector for an elongated radiation source which is arranged in a profiled holder, with a reflection surface whose main axis is substantially parallel to the axis of the radiation source, where the holder is shaped as a body, with a bearing surface for a radiation-reflecting metal strip and with parallel edges provided with stop means which each come into contact with one of the anti-reflection strip's parallel edges which are resiliently pressed against the support surface, where the support surface is provided with at least one groove which is arranged behind the radiation source and whose longitudinal direction is mainly parallel to the main axis, and where the strip material has such a \ b'feddé 'that' in:'mounted position, the strip is held between the stop members and is permanently bent in the groove under elastic deformation..
Det. er tidligere kjent reflektorer av denne art,mene de er ikke utstyrt med kanal for et kjølemedium i direkte varmekontakt med reflektoren......, The. are previously known reflectors of this kind, but they are not equipped with a channel for a cooling medium in direct heat contact with the reflector......,
Hensikten med oppfinnelsen - er å tilveiebringe en reflektor hvor en slik kjølemulighet er oppnådd-på enkel og billig måte. The purpose of the invention - is to provide a reflector where such a cooling option is achieved - in a simple and cheap way.
Dette oppnås ifølge oppfinnelsen ved at sporet eller sporene og strimmelen tilsammen danner en eller flere kanaler, av hvilke én er forbundet med en kilde for et kjølemedium, mens den resterende del er forbundet med kanalen ved tverrgående forbindelser som danner et nett av kjølekanaler. This is achieved according to the invention by the track or tracks and the strip together forming one or more channels, one of which is connected to a source for a cooling medium, while the remaining part is connected to the channel by transverse connections that form a network of cooling channels.
Fortrinnsvis er strimmelen på noen steder over hele leng-, den av kanalen eller kanalene forsynt med åpninger som er presset ut av strimmelmaterialet og som sett i hovedaksen, danner gitterformede ledeorganer for kjølemediet, slik at dette ledes langs overflaten av strimmelen i baner på tvers av strålingskildens lengdeakse. Preferably, the strip is in some places over the entire length of the channel or channels provided with openings which are pressed out of the strip material and, as seen in the main axis, form lattice-shaped guiding means for the cooling medium, so that this is guided along the surface of the strip in paths across longitudinal axis of the radiation source.
Med fordel kan det mellom overflaten av reflektorlegemet som bærer strimmelen og strimmelen være anordnet et viskost varme-absorberende materiale for å øke varmeoverføringen fra strimmelen til legemet. Advantageously, a viscous heat-absorbing material can be arranged between the surface of the reflector body carrying the strip and the strip to increase the heat transfer from the strip to the body.
Noen utførelseseksempler på oppfinnelsen skal forklares nærmere under henvisning til tegningene. Fig. 1 viser et tverrsnitt gjennom en reflektor ifølge oppfinnelsen. Some embodiments of the invention will be explained in more detail with reference to the drawings. Fig. 1 shows a cross-section through a reflector according to the invention.
Fig. 2 viser på samme måte som fig. 1 en reflektor med Fig. 2 shows in the same way as fig. 1 a reflector with
en modifisert utførelse av reflektorstrimmelen. a modified version of the reflector strip.
Fig. 3 viser et snitt langs linjen III-III på fig. 2. Fig. 3 shows a section along the line III-III in fig. 2.
Fig. 4 viser et lengdesnitt langs linjen IV-IV på fig. 2. Fig. 4 shows a longitudinal section along the line IV-IV in fig. 2.
Reflektoren på fig.-.l består av et refléktorlegeme 1 med en elastisk fjærende refleksjonsstrimmel 2 som er festet inne i bærelegemet 1. Strimmelen 2 holdes presset mot bærelegemets over-flate mellom to parallelle kanter eller ribber 3 og- H av bærelegemet 1 og som danner stoppeorganer. The reflector in fig.-.l consists of a reflector body 1 with an elastically springy reflection strip 2 which is fixed inside the support body 1. The strip 2 is held pressed against the surface of the support body between two parallel edges or ribs 3 and H of the support body 1 and which form stopping organs.
Reflektoren er forsynt med en gjennomsiktig dekkplate 5. The reflector is provided with a transparent cover plate 5.
I reflektoren er også anordnet en langstrakt strålingskilde 6 med en kolbe 7 av kvartsglass, Denne strålingskilde kan være en rørformet, infrarød lampe med kontakter i begge ender. An elongated radiation source 6 with a flask 7 of quartz glass is also arranged in the reflector. This radiation source can be a tubular, infrared lamp with contacts at both ends.
Reflektorlegemet 1 er forsynt med en parabolsk, elliptisk eller lignende flate hvis hovedakse går parallelt med lyskildens 6 akse. Ved denne utførelse har reflektorlegemet en elliptisk tverr-snittsform som er beregnet på lyskilden 6, 7. Brennpunktene for den elliptiske flate er anordnet i strålingskildens akse og i punkt-et 8. The reflector body 1 is provided with a parabolic, elliptical or similar surface whose main axis runs parallel to the axis of the light source 6. In this embodiment, the reflector body has an elliptical cross-sectional shape which is intended for the light source 6, 7. The focal points for the elliptical surface are arranged in the axis of the radiation source and in the point 8.
Bæreflaten av legemet 1 er forsynt med et langstrakt spor The bearing surface of the body 1 is provided with an elongated groove
9 som strekker seg i hele legemets lengde. 9 which extends the entire length of the body.
Sporet 9 virker som et ekspansjonsspor i hvilket en del 10 av strimmelen kan presses inn under virkning elastisk deforma-sjon. Dette kan opptre når strimmelen presses inn mellom stoppeorganene 3 og H eller når strimmelen utvider seg som følge av varme-påvirkning. I ethvert tilfelle virker sporet 9 som en ekspansjons-mulighet for deformering av strimmelen 2. The groove 9 acts as an expansion groove into which a part 10 of the strip can be pressed under the effect of elastic deformation. This can occur when the strip is pressed between the stoppers 3 and H or when the strip expands as a result of heat. In any case, the groove 9 acts as an expansion possibility for deformation of the strip 2.
Veggene i sporet 9 sammen med strimmelen danner en kanal som kan være forbundet med en kilde for et kjølemedium i en sentral kanal 11. The walls of the groove 9 together with the strip form a channel which can be connected to a source for a cooling medium in a central channel 11.
Fig. 2, 3 og 4 viser en annen utførelse av en reflektor ifølge oppfinnelsen, hvor det er anvendt samme henvisningstall som på fig. 1. Fig. 2, 3 and 4 show another embodiment of a reflector according to the invention, where the same reference number as in fig. 1.
På fig. H er vist den sentrale kanal 11. I kanalen 9 er det anordnet to åpninger 14 hvor luft strømmer til lampeforbindels-ene 16 for å kjøle disse deler av lampen. Refleksjonsstrlmmelen er videre forsynt med et antall slisser 12 som er presset ut av materialet som tunger 13. Sett i reflektorlegemets hovedakse danner disse tunger 13 kjølefinner. På grunn av disse slisser vil luften strømme på tvers av reflektoraksen og blant annet trekke med seg luft fra omgivelsene av kvartsrøret 7 og også kjøle dette slik som tydelig vist på fig. 2. Hvis dekkplaten 5 fjernes vil kjøleluften som oppvarmes av strålingskilden unnvike gjennom reflektorens op-tiske åpning og kan anvendes for tørkeformål. In fig. H shows the central channel 11. In the channel 9, two openings 14 are arranged where air flows to the lamp connections 16 to cool these parts of the lamp. The reflection strip is further provided with a number of slits 12 which are pressed out of the material as tongues 13. Set in the main axis of the reflector body, these tongues 13 form cooling fins. Because of these slits, the air will flow across the axis of the reflector and, among other things, will draw in air from the surroundings of the quartz tube 7 and also cool this as clearly shown in fig. 2. If the cover plate 5 is removed, the cooling air heated by the radiation source will escape through the reflector's optical opening and can be used for drying purposes.
Bærelegemet 1 er på utsiden forsynt med langsgående slisser 15 for sammenkopling av flere reflektorer til en enhet. Dette kan The support body 1 is provided on the outside with longitudinal slits 15 for connecting several reflectors to one unit. This can
gjøres ved å skyve inn forbindelsesorganer 17 i sporene 15 i mot hverandre vendende slisser i bærelegemene (se fig. 2). Forbindelse av to reflektorer etter hverandre i lengderetning kan skje ved inn-føring av forbindelsesstenger 19 i slissene 15 som vist på fig. 1. is done by pushing connecting members 17 into the grooves 15 in opposite slots in the support bodies (see fig. 2). Connecting two reflectors one after the other in the longitudinal direction can be done by inserting connecting rods 19 in the slots 15 as shown in fig. 1.
