ADAPTOR TIL ANBRINGELSE PÅ LAVENERGILYSSTOFROR SAMT ANVENDELSE AF ADAPTORENADAPTOR FOR APPLICATION ON LOW ENERGY LIGHT STORES AND USE OF ADAPTOR

5 Opfindelsen angår en adaptor til anbringelse på lavenergi-lysstofrør af forskellige fabrikater og modeller til understøtning for en lampeskærm, hvilken adaptor i det væsentlige er kugleformet, for eksempel en kugleskal, og forsynet med en åbning for lysstof rørets top, således at den kan 10 nedpresses over lysstofrøret.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an adapter for mounting on low-energy fluorescent lamps of various makes and models to support a lampshade, which adapter is substantially spherical, for example, a ball shell, and provided with an aperture for the fluorescent tube top. is pressed down over the fluorescent lamp.

Sådanne lavenergilysstofrør kaldes i daglig tale for "sparel amper" .Such low-energy fluorescent tubes are commonly referred to as "sparse amps".

15 Fra GB offentliggørelsesskrift nr. 2.177.488 kendes en understøtning for en almindelig kendt lampeskærm til anbringelse på et lavenergirør, som er udformet som en diffuser.15 From GB Publication No. 2,177,488, a support for a generally known lampshade for mounting on a low energy tube known as a diffuser is known.

Fra GB 2 228 789 A kendes en adaptor, som er udformet som 20 en skal med en åbning, som svarer til enten lysstof rørets ydre eller til soklens ydre. Herved kan adaptoren skydes ned over lysstofrørets top og fastholdes ved fastklemning omkring lysstofrøret eller soklen.From GB 2 228 789 A there is known an adapter, which is designed as a shell with an opening corresponding either to the exterior of the fluorescent tube or to the exterior of the base. This allows the adapter to be pushed down over the top of the fluorescent lamp and held by clamping around the fluorescent tube or base.

25 For at øge fastholdelsen er åbningen forsynet med et udad-ragende randparti med klemvirkning mod lysstofrøret eller soklen.To increase retention, the opening is provided with an outwardly extending edge portion with clamping action against the fluorescent tube or base.

Denne adaptor har imidlertid den ulempe, at den let lader 30 sig forskyde, da fastholdelsen sker ved en simpel klemning uden nogen form for styring. Ved påsætning af for eksempel en lampeskærm med klembøjle vil adaptoren let blive påvirket i sideretningen og gå ud af sit klemindgreb og derved enten sidde skævt på lampen eller gå løs.This adapter, however, has the disadvantage of being easily displaced since the holding is done by a simple clamping without any control. By attaching, for example, a lampshade with a clamping bracket, the adapter will easily be influenced in the lateral direction and exit from its clamping engagement, thereby either sitting skewed on the lamp or loosening.

3535

Ved ifølge opfindelsen at udforme adaptoren med en åbning i DK 171567 B1 2 form af et kryds til dannelse af flige, idet fligene ved presning af kuglen mod lysstofrørets top fungerer som styr og fastholdelse af adaptoren direkte på lysstofrøret, opnås på en overraskende enkel måde en sikker styring og fast-5 holdelse af adaptoren på lysstofrøret.By forming the adapter with an opening in DK 171567 B1 2 in the form of a tab to form tabs, the tabs pressing the ball towards the top of the fluorescent lamp act as guide and holding the adapter directly on the fluorescent lamp, a surprisingly simple way is achieved. safe control and retention of the adapter on the fluorescent lamp.

Herved kan en lampeskærm, som er dimensioneret til brug på sædvanlige glødelamper, anbringes på adaptoren på lysstofrøret uden fare for, at adaptoren forskydes eller løsner 10 sig.Hereby, a lamp shade sized for use on conventional incandescent lamps can be placed on the adapter on the fluorescent lamp without the risk of the adapter being displaced or loosened.

Endvidere er adaptoren anvendelig til beskyttelse af de skrøbelige lavenergilysstofrør under transport, ved brug af arbejdsbelysning med håndlamper og i bredere forstand til 15 benyttelse ved inden- og udendørs reklamebelysning, samt i forskellige farver med henblik på reklame og information.Furthermore, the adapter is useful for protecting the fragile low-energy fluorescent lamps during transport, using working lighting with hand lamps and in a wider sense for use in indoor and outdoor advertising lighting, and in various colors for advertising and information.

Adaptorens materiale har en hårdhed, der tilsikrer lavener-gilysstofrørene en god beskyttelse, samt en blødhed, der 20 absorberer stød, og en tilpasset elasticitet til lampeskærmens klemholdere, samt stivhed nok til at holde lampeskærmene fast omkring lavenergilysstofrørene, hvilket de kendte metaldiffusere ikke er i stand til.The material of the adapter has a hardness which provides good protection for the low-energy fluorescent tubes, as well as a shock absorbing softness, and an adapted elasticity for the lampshade clamp holders, as well as stiffness enough to hold the lampshades around the low-energy fluorescent tubes, which are not known in the metal diffusers. capable of.

25 Størrelsen af adaptoren kan varieres og tilpasses til nuværende og fremtidige modeller af lavenergilysstofrør.25 The size of the adapter can be varied and adapted to current and future models of low energy fluorescent lamps.

Kendte emner til brug for lampeskærme med klemholdere er hidtil fremstillet i metal og opbygget som en holder, der 30 hviler på lavenergirørets sokkel, idet det særlig bemærkes, at disse dels kan blive farligt strømførende og endvidere kun har et hvilepunkt i bunden af holderen, hvilket bevirker, at der ved let berøring af skærmene kan opstå livsfarlige strømførende forbindelser og situationer, når der ret-35 tes på skærmene.Known items for use with lampshades with clamp holders are heretofore made of metal and constructed as a holder resting on the base of the low-energy pipe, noting in particular that these can be dangerously live and furthermore have only a resting point at the bottom of the holder, which causes, that light touching of the screens can cause life-threatening live connections and situations when the screens are fixed.

DK 171567 B1 3DK 171567 B1 3

Adaptoren kan fremstilles i passende værktøjer, så den opfylder de særlige krav i forbindelse med tilkobling til lampeskærmenes klemmer og på grund af lavenergilysstofrøre-nes forskellige størrelser og modeller. Den teknologi, der 5 er kendt fra produktion af bolde og lignende genstande i forskellige farver og størrelse, f.eks. af plast eller gummi, vil kunne anvendes i forbindelse me'd fremstillingen af adaptoren ifølge opfindelsen.The adapter can be manufactured in suitable tools to meet the special requirements for connection to the lampshade terminals and due to the different sizes and models of the low-energy fluorescent lamps. The technology known from the production of balls and similar objects in different colors and sizes, e.g. of plastics or rubber may be used in connection with the manufacture of the adapter according to the invention.

10 Adaptoren kan være fremstillet af mange forskellige materialer, f.eks. PVC/Polyethylen eller andre polyolefiner. Materialet skal blot have passende egenskaber, så lavenergi-lysstofrørenes meget lille varmeudvikling ikke udskiller flygtige giftstoffer af materialet, og således at materia-15 let er modstandsdygtigt over for den ringe varme, der udvikles i lavenergilysstofrørenes sokkel, så uønsket deformitet af kuglen ikke opstår.The adapter may be made of many different materials, e.g. PVC / Polyethylene or other polyolefins. The material must have only suitable properties so that the very low heat generation of the low-energy fluorescent lamps does not separate volatile toxins from the material, and so that the material is resistant to the low heat generated in the base of the low-energy fluorescent lamps so that undesirable deformity of the sphere does not occur.

Endvidere forudsættes det, at plastmaterialet ikke er gas 20 og lufttæt, således at varmen fra lavenergilysstofrørene kan udskilles gennem materialet og ikke optager varme fra lavenergilysstofrørets sokkel, hvorfra varmen opstår, idet hensigten hermed beror på, at kuglen ikke forårsager, at lyskildens levetid nedsættes.Furthermore, it is assumed that the plastic material is not gas 20 and airtight, so that the heat from the low-energy fluorescent tubes can be separated through the material and does not absorb heat from the base of the low-energy fluorescent tube, from which the heat arises, the intention being that the ball does not reduce the life of the light source.

Opfindelsen tager hensyn til producenter af lampeskærme med fjederklemmer, der er beregnet til konventionelle glædepærer, som skærmens klemmer spænder over, som vist på fig. 8.The invention takes into account manufacturers of lamp shades with spring clamps intended for conventional light bulbs over which the clamps of the shield span, as shown in FIG. 8th

15 Adaptoren 1 har form af en kugle og en størrelse, der kompenserer for den konventionelle glødepære, idet denne presses ned over lavenergilysstofrørene 4 via udskæringer 3 eller udstansninger udformet som et kryds i bunden af kuglen til dannelse af flige, idet fligene ved presning af kuglen 20 mod lysstofrørets top fungerer som styr og fastholdelse samtidig med, at kuglens inderste top hviler på lysstofrøret, som vist på fig. 1-3.The adapter 1 is in the form of a ball and a size which compensates for the conventional incandescent bulb as it is pressed down over the low-energy fluorescent lamps 4 via cut-outs 3 or punches formed as a junction at the bottom of the ball to form tabs, the tabs pressing the ball 20 towards the top of the fluorescent lamp acts as guide and retention while the inner top of the ball rests on the fluorescent lamp, as shown in FIG. 1-3.

Det er således ikke afgørende, at kuglens bund støtter på 25 lavenergilysstofrørenes sokkelstykke, idet en fastholdelse væsentligst består i forholdet mellem hvilepunktet øverst på lavenergilysstofrøret, og kuglens tætsluttende bundudskæring et vilkårligt sted på selve lysstofrøret/-ne bevirker, at lavenergilysstofrørene anvendes som bæreenhed for 30 klemmelampeskærmene i lighed med den konventionelle glødepære beregnet for lampet og bordbelysning. Endvidere vil kuglen kunne anvendes som emballagefyld i kartoner til sikring mod stød og overlast, der kan opstå under distribuering, idet kuglen kan monteres på lavenergilysstofrørene, 35 forinden disse emballeres, og/eller kan indgå som en del af selve emballagen med henblik på stødabsorption.Thus, it is not essential that the bottom of the ball is supported on the base of the low-energy fluorescent lamps, since a retention essentially consists of the relationship between the resting point at the top of the low-energy fluorescent tube and the ball-sealing bottom cutout is used at any location on the fluorescent tube (s), the squeeze lamp shades similar to the conventional bulb designed for the lamp and table lighting. In addition, the ball can be used as packaging filling in cartons for protection against shocks and overloads that may occur during distribution, the ball being mounted on the low-energy fluorescent tubes prior to packaging, and / or being part of the packaging itself for shock absorption.

DK 171567 B1 5DK 171567 B1 5

Reklamebelysning udvendig som indvendig, hvor lavenergilys-stofrør anvendes, kan monteres med klare såvel som farvede kugler uden brug af lampeskærme med klemmer; således figu-5 rer/bogstaver m.v. på f.eks. en lystavle/kæde kan anvendes i lighed med farvede konventionelle glødepærer.Advertising lighting exterior and interior, where low-energy light fabric tubes are used, can be mounted with clear as well as colored balls without the use of lamp shades with clamps; thus figures / letters, etc. on e.g. a light board / chain can be used similar to colored conventional incandescent bulbs.

Adaptoren 1 har således den fordel, at bundfligene sidder tætsluttende om lavenergirøret 4 i bunden og med hvilke-10 punktet på indersiden af kuglen således, at kuglen fastholdes omkring lavenergirøret 4 og dermed danner en helhed, som udgør en stabil fastholdelse for lampeskærme 5, som vist på fig. 8 og 9.Thus, the adapter 1 has the advantage that the bottom tabs sit tightly around the low-energy tube 4 at the bottom and with which point on the inside of the ball so that the ball is held around the low-energy tube 4 and thus forms a unit which forms a stable retention for lamp shades 5, which shown in FIG. 8 and 9.

15 Adaptoren kan diametralt fligene 3 i bunden af kuglen være forsynet med to parallelle udskæringer 2, som vist på fig.15 The adapter may have diametrically the tabs 3 at the bottom of the ball provided with two parallel cut-outs 2, as shown in FIG.

4.4th

Herved kan en lampeskærm 5 med fjederklemmer 7, som vist på 20 fig. 9, gå i indgreb med udskæringerne 2 samtidig med, at disse udskæringer 2 virker som varmeafledningskanaler for den varmeenergi, som lavenergirørets bundstykke frembringer under drift.Hereby a lamp shield 5 with spring clamps 7, as shown in FIG. 9, engage the cut-outs 2 at the same time as these cut-outs 2 act as heat dissipation channels for the heat energy generated by the low-energy pipe's bottom piece during operation.
