Luminous element.
[0001] The invention relates to a self-sufficient, permanently luminous body for identifying important points brightness, poor light conditions and in the dark, especially for installation in instruments or for attachment to objects, the quickly in emergency situations must be found, comprising a glass capsule tritiumgaslichtqülle (GTLS) as designed, in a sheath which is fixed with a transparent viewing area. [0002] Autonomous self-luminous or phosphorescent bodies are particularly in clocks, steady or in other instruments on required, for example in the cockpit of aircraft, the important locations on pointers and labels highlight the instruments. It is also possible where there is little light or in the dark to the viewer, to phase out of the instruments. Other application examples (chine and grain) are arms aid visor. Such self-luminous devices do not have access to a power supply and are often very small. Other applications also such larger self-illuminating or afterglowing body are produced. In some countries emergency exits, light switch, door handles or other objects or locations will be characterized, which must be a sudden power failure quickly found. Security personnel also identifies certain important articles, such as a flashlight, with such self-illuminating markers. [0003] Are known in particular self-luminous tritiumgaslichtqüllen, even after the English term Gaseous tritium-lite or sources of short GLTS mentioned. These are closed glass capsules, coated with a phosphorus which are filled with the radioactive tritium gas easily and inwändig. This radioluminiszierende capsules lamps, thanks to the long half-life the tritium gas, for decades and have proven itself. Since their permanent luminance but is rather weak, they are in brightness, where they operate white, remarkably little. At dusk or in the dark they are observed by the human eye only after a while, when the eye has used to the darkness. [0004] Also known are optical fibers, which the ambient light over a large area and collecting at a specific, again releasing smaller surface, whereby this bright light. The large surface disadvantage, which must be exposed to the light, and the fact, that they are not light in the dark. [0005] As a further alternative phosphorescent luminescent colors known, often as pointers and points of watches and on to find are steady. These are either - or photo-luminescent radios, wherein temperature-luminescence colors are also known. This partial long and highly luminous colors are difficult for contracts and must be well protected as environmentally, especially moisture. [0006] It is the task of the present invention, an input indicated, illuminating body permanently to describe, in the brightness, at twilight, poor light conditions, in the dark and is visible, and can be simply and securely mounting allows a cost-effective production in large series. This luminous element can also be universal in many appliances are installed, without adjustments that are necessary. [0007] The problem is solved by the features of the independent Patent Claim. Further advantageous constructions are specified in the dependent claims. [0008] Invention is at a named above, self-sufficient, at least in the region between the illuminating body permanently GTLS glass capsule and the viewing area a pigmented layer with phosphorescent. [0009] By this arrangement the invention light bulbs on the entire viewing surface very bright daylight, because the pigments the daylight receiving and highly reflecting. In the gradual transition from daylight for twilight is the luminous element to see also very well, because the pigments have stored energy, which they in the next 10 to 20 minutes in the form of light slowly dispensing. In this time the eye is used to the darker environment and can now the weaker, but constant luminous GTLS glass capsule according and perform better. Since the GTLS glass capsule from the viewing direction is arranged behind the phosphorescent pigments always from, the viewer sees the luminescent area both in daylight and in darkness always at the same place. It notices not, when the luminosity of the phosphorescent pigments dispersed and slowly the capsule increases with increasing sensitivity to the eye GTLS glass, since always the same illuminated viewing surface. [0010] The GTLS glass capsule can be use in all said applications, thus in particular also, but not only, as sight aid, for marking on watches, steady and instruments, and indicative emergency aid. [0011] GTLS glass capsules having a diameter of about 1 mm for small is the pigmented layer is about 0.1 - 0.8 with the afterglowing mm thick, depending on, as the proportion of these pigments is high. Wherein larger and thus may also be thicker layer light stronger GTLS glass capsules. [0012] The invention alternatively simply and cheaply in large series lamp manufacturing instruments incorporating, as it simply as a solid structural body is manageable. [0013] In the following the invention is explained with reference to the drawings. It shows: A schematic representation of the invention in section 1 figfig. a luminous body in a simple shape; A cross-section an alternative embodiment 2 figfig.; A further alternative embodiment figfig. 3 a cross section; 4 A cross section of the embodiment according to figfig. figfig. 2, installed in an apparatus; Figfig. 5a, 5b an alternative configurations of the viewing area and the lens; 6 A cross section a further figfig., alternative embodiment. [0014] 1 And 2 show schematic representations of the figfig. invention illuminating bodies 1st these are autonomous, permanently luminous body 1, the usually are rotationally symmetrical. The core glass capsule 2 tritiumgaslichtqülle (GTLS) designed as each define an, trade as usual in rod-like, closed structures described obtainable and input. Each GTLS glass capsule 2 permanently lit during decades can be seen well in the dark and by a human eye, accustomed to the darkness something once. For the lamp a GTLS glass capsule 2 is neither a battery, a power source still, another energy supply, for example in the form of light, necessary. A GTLS glass capsule 2 is permanently self-sufficient brightly. [0015] Since a GTLS glass capsule 2 a radioactive gas contains, the break of the glass enclosure is free, it must be well protected in a housing installed, to satisfy the legal conditions of most countries. This is why the GTLS glass capsule 2 in a sealed envelope with a transparent viewing surface 3 4 fixed. According to the viewing surface part of a transparent member 8 4 1 figfig. can be, as the outer surface of a lens 17, for example of glass, ceramic or plastic. This component is at one end of a tubular sleeve sealingly mounted 3 8, for example by an interference fit. The sheath 3 can be for example of metal or plastic. [0016] Alternatively, as in figfig. 2 represented, the viewing surface 4 may be part of the sheath 3, as transparent, unilaterally closed tube is designed integrally. The component 8 is thus formed on the casing 3. In both cases the sheath 11 has an interior space and a closed on 3, front end and a rear end or the rear end 10 open opposing this 10th only for the manufacture of the luminous element 1 is open, it is also closed after completion, for example by means of a filler 7 with an adhesive. [0017] In the closed interior space 11 of the sheath 3 each is the GTLS glass capsule 2 arranged. Invention is at least in the region between the capsule and the viewing surface 4 a 2 GTLS glass afterglowing pigments 5 arranged offset layer 6. This has the effect first, in that the lamp 1 by a color such as green or blue seen viewing surface 4 and extending in from the environment better than a GTSL glass capsule 2 lifts, the daylight is white. The fluorescent pigments are also is 5, whereby the force for enhanced viewing area 4. A second effect is achieved disappear of light: then lights the pigments in the layer still 5 6, whereby in addition to the capsule during the next minutes 2 this GTLS glass reinforced lamps, accustomed to the darkness until the eye. After the decay of the luminosity of the light on the GTLS glass capsule 5 pigments through the layer 6 with the pigments 5 2 further and finally by the viewing surface through 4, any appreciable reduction of the luminosity of the resulting GTLS glass capsule 2 leads. [0018] Such a lamp 1 according to the invention is ideal for identifying important points brightness, poor light conditions as well as in the dark. It can be simply instruments and apparatus 18 to incorporate or objects or locations, must be found quickly in emergencies, attaching. [0019] As phosphorescent pigments are preferably used 5 Fotolumineszenzen, preferably comprising strontium aluminate (SrAI2 04 ). On the market are different phosphorescent pigments with different colors on the market long 5 obtainable, for example under the name of super LumiNova® company. Nemoto & Co. Ltd, in Japan. These and other lamps very long and hard and are ideal for the lamp 1 according to the invention. [0020] To form the layers 6, the afterglowing pigments mixed with a mass and can 5 are processed with a desired diameter rod, of which finally thin disks, which form the layers 6, are cut. Such a layer 6 in the casing 3 is arranged on the inside of the viewing area 4, before the GTLS glass capsule 2 is introduced behind it. It is important, that the layer 6 between the viewing area and the GTLS glass capsule 2 4 is arranged. The shell 3 is finally sealed at its open end 10, so that the pigments in the interior of the sleeve 5 11 3 remain protected and both the layer 6 and the moisture GTLS glass capsule 2 remain fixed. [0021] Alternatively or additionally is the GTLS glass capsule 2 inside the sheath 3 of a filler 7 surround. This filler 7 voltages between the capsule and the sheath 2 attenuates GTLS glass 3, whereby a glass broke the GTLS glass capsule 2 wherein temperature changes upon the occurrence of shocks can be prevented or substantially. The filler preferably comprises an adhesive 7, so that the casing 3 is closed by the filler 7 directly. It is sufficient to, when the adhesive is about 5 - 10 Voij. 7% of the filler constitutes. In some cases the amount to about 20 Voij also. % or more increased. [0022] As in 7 of the luminous element 1 with the filler 3 figfig. represented can the phosphorescent pigments 5 be offset. Turning the GTLS glass capsule 2 surrounded on all sides by pigments 5. In this case the inserted layer 6 can be omitted. [0023] Since the commercially available GTLS glass capsules 2 are configured as elongate tube usually, also preferably have a cylindrical wall on the casings 3 9. By the concentric arrangement of the capsules 2 in the covers 3 is achieved GTLS glass, that the filler 7 always the same thickness by the circumferential surface of the capsule 2 has GTLS glass. [0024] In a preferred embodiment of the luminous element 1 is the sheath 3 of glass, in particular of sapphire glass, ceramic or plastic. If the shell 3 is entirely transparent, its entire surface can receive energy in the form of light, the phosphorescent pigments stored in 5 and later discharged as light. Thereby increasing the viewing surface 4. [0025] Such illuminating bodies 1 are especially well suited, lying with their cylindrical walls 9 to be mounted on a support, for example a sign as arrow generate a developed surface. The luminous element 1 can also be mounted on reflectors, lamps are known as office. The rear sides of the lamp 1 may also receiving and delivering light. [0026] The rear, formerly open end of the sheath is sealed 10 3, for example with an adhesive, with glass, ceramic or plastic. The sheath 3 can also on the surface, the opposite the viewing surface 4 is arranged, with a light-reflecting layer 12 be provided. The emitted light is reflected back in the rear forward, in the direction of the viewing area is also from outside through said viewing surface 4 4th incident light reflected and thus enhances the visibility of the luminous element 1 also. [0027] The lamp 1 as a light point is needed, for example in instruments or devices 18, 19 in the apparatus 18 in a bore provided therefor it is so introduced, as in figfig. 4 represented. The surface is then usually the closed 4 BERT to respect, front end of the sheath tube 3 as designed. It can optionally be used according to a luminous element 1 or 3 figfig. 1.2, wherein the comments as 1 and 3 can also combine figfig.. [0028] The sheath 3 of the luminous element 1 has an outer, leaving blank surface 13 on the viewing surface 4. This is preferably at least partially covered with a light-reflecting coating 14, to optimize the light effect. For example a desired light reflection by a thin, deposited layer 14 of silver, a gold, aluminum or chromium are achieved. Additionally or alternatively as a shrink tube are used as coating can my thicker layer, which has a reflective inner surface. [0029] Such a sheath 14 also acts as a damping mat between the lamp 1 and the device 18, 19 is installed in its bore it, damage by mechanical or thermal stresses or shocks to avoid. [0030] The casing 14 can also in addition to the viewing surface 4 a second recess having recess 15, which in the installed state an outer 16 allows light incident light, if this is provided in the device 18 accordingly. If the installation position of the luminous element 1 away from edge of the device 18 is provided, can be guided by light guide light from device 15 (not shown) edge to the second recess. Thanks to this additional light incidence in the afterglowing pigments can more energy stored, whereby the luminance is increased. [0031] The sheath 3 can be configured to a lens surface in the region of the freighting 4 17, in particular to a scattering - or collecting lens. The viewing surfaces 4 figfig. according to 1, 2, 3 and 4 are configured as a collecting lens. [0032] 5A and 5b is the viewing area in the figfig. 4 configured schedule. It allows the luminous element 1 in a bore 19 completely closes the viewing surface 4 become incorporated flush with the apparatus wall 18 collects no dirt around the viewing surface 4 at such off. the luminous element 1 is also well protected and before mechanical effects. [0033] The contour of the interior space 11 in the direction of the planar viewing surface 4 may, as in figfig. 5a represented, be convexly configured, whereby a collection lens 17 is formed convexly canvas. On the other hand into the interior space 11 in the direction 5b figfig. is planar viewing surface 4 concavely configured, whereby a concavo-planar scattering lens 17 is formed. An autonomous, permanently illuminating object includes a sheath that defines an interior space in which is disposed a glass capsule containing a gaseous tritium light source. The sheath defines a transparent region. A layer of photoluminescent pigments is disposed between the glass capsule and the transparent region of the sheath.
