Definitions
- the invention relates to a reflector lamp according to the preamble of claim 1.
- Such a reflector lamp is previously known, for example, from EP-A 572 400. It is an incandescent lamp, the base of which is partly formed by an insert part at the end of the neck part of the reflector. This insert must be connected to the neck part of the reflector by means of putty. Disadvantages of this base are that it is difficult to manufacture and is not particularly precise. In addition, this construction leads to an extension of the overall length of the reflector lamp, since space is required to hold the insert part below the bulb in the neck part.
- the particular value of the invention lies in the fact that the manufacture of the lamp is considerably simplified and at the same time the possibility created to make the lamp more compact and in particular to continue to ensure a high level of operational safety of these lamps.
- the reflector lamp according to the invention has considerable cost and procedural advantages over the prior art.
- Both a luminous element and an electrode are possible as illuminants (see, for example, the reflector discharge lamp in US Pat. No. 4,935,660).
- the invention is particularly suitable for HV and MV lamps. However, it is not out of the question to apply them to NV lamps.
- a particular advantage is that the concept of the integrated base allows the power supply system to be designed in such a way that there are no contact problems due to contact resistances, which are often in the low voltage range (below 80 V) due to small contact areas in electrical connections occur. Age-related corrosion causes the high contact resistance, which results in voltage drops in the supply lines. A significantly lower voltage is then applied to the illuminant itself during operation.
- the reflector lamp with a base on one side is characterized by the following features: a hermetically sealed bulb with a filling and a lamp, a reflector consisting of a base body bearing a reflector contour and a neck part attached to the rear, a base which is attached to the Neck part attaches, and which has two or more metallic contact pins with cylindrical thickenings at the distal end, and a power supply system that provides an electrical lead for the lamp.
- the base is made entirely of the material of the neck part and molded as an integral part directly on the neck part of the reflector.
- the bulb is normally a separate part made of hard glass or quartz glass inside the reflector, which is in particular squeezed on one or two sides.
- the piston is formed by the reflector itself, the reflector having a hermetically sealed cover plate (sealed beam technology).
- the reflector lamp is usually equipped with a reflector made of glass, but temperature-resistant plastic is also suitable. These materials have a substantially better dimensional stability and tighter tolerances than ceramic materials, so that the base sits better and more precisely in the socket. Ceramic is also more expensive and heavier.
- the invention is particularly advantageous for high-voltage or medium-voltage lamps, that is to say for an operating voltage of at least 80 V. Previously, the compactness of suitable reflector lamps left much to be desired.
- the base is formed by a flat wall with an inner and an outer end face, which is arranged transversely to the reflector axis and closes the neck part. It has axially parallel openings for contact pins.
- the contact pins are advantageously designed as contact pin sleeves with an inner bore, the bore in the sleeve extending at least over part of the sleeve length or also over its entire length.
- the contact pin sleeves can be attached in a simple manner in that the sleeves have an outwardly bent edge on the piston side and a disk-shaped collar approximately in the middle of the sleeve length, between which the wall of the base is locked.
- At least one raised bead is advantageously arranged on the outer end face of the wall, the thickness of which corresponds at least (preferably equal) to that of the collar of the sleeve.
- a particularly interesting application for general lighting is a reflector lamp, in which the lamp is an incandescent lamp with a bulb pinched on one side, which contains a luminous element and internal power supply lines, the power supply lines being designed in such a way that they have an inherent securing effect.
- Possible design options for an inherent backup are set out in a number of documents:
- the inherent securing effect is realized in a particularly advantageous manner as follows:
- the inner power supply lines connect the ends of the luminous bodies to sealing foils embedded in the pinch and are embedded in the pinch over part of their length, at least one of the power lines consisting of an uncoiled wire.
- the inherent securing effect is achieved in that at least one of the two inner power supplies is made of a wire with a diameter of at most 130 ⁇ m, preferably at most 80 ⁇ m, which is embedded in the pinch over a length of at least 2 mm, the Distance d between the power supply lines and the applied voltage V interact so that in the event of an arc occurring between the power supply lines, the field strength V / d acting there is greater than 100 V / cm, and preferably between 200 and 400 V / cm lies. Further details can be found in DE-GM 296 07 132.
- a specific advantage of an uncoiled wire in comparison to a single coil is that the mass of the current supply formed therefrom is considerably less with the same length embedded in the crimp. The evaporation of the wire material in the capillary therefore proceeds much faster. The arc extinguishes earlier and the response time of the inherent fuse is much shorter than with other fuses. In addition, the energy introduced into the arc is considerably smaller.
- uncoiled wire is also to be understood to mean a wire which was originally simply coiled, but which has been drawn out to give an elongated, spirally wound wire.
- the pitch is 10 to 100 times
- the wire has not yet completely lost its original spiral shape, but the windings are so far apart that there is no more tube-like cavity when squeezing.
- the really accommodated wire length is thereby significantly longer than with a completely coiled wire piece, in which the really accommodated wire length is identical to the crimped wire length.
- the inner power supply preferably has a diameter of more than 15 ⁇ m.
- the filament and the inner power supply can be made as a unit from a single wire, i.e. the inner power leads are the uncoiled filament ends.
- the wall is normally attached to the neck part at right angles.
- the base can also be designed Tet that the neck part merges into the flat wall by means of a radial circumferential slope.
- a reflector lamp with a high degree of compactness which is based on one side, has the following features in particular:
- a luminous element with two ends which is bent in a U, V or W shape and is held in the bulb without a frame structure (wire frame, quartz beam).
- the latter is usually difficult to achieve, especially for HV or MV lamps.
- a particularly elegant option for dispensing with a wire frame is that at least one heat-resistant holding means fixes the luminous element in a manner known per se.
- a high degree of compactness is particularly difficult to achieve with MV or HV lamps, since they are normally operated with a fuse.
- the operating voltage is at least 80 V.
- the power supply system therefore advantageously has internal power supplies that are designed in such a way that they have an inherent securing effect.
- the filament can be arranged axially or bent in a U, V or W shape.
- the luminous element is subdivided into two luminous sections which are separated from one another by a non-luminous base part.
- MV applications mains voltages of approximately 110 V
- a lamp pinched on one side with an axial luminous element is used. It is advantageous here that only the end of the filament adjacent to the pinch is connected via a power supply with an inherent fuse the sealing film connected.
- the other power supply which is guided as a setting wire to the end distant from the pinch, is a solid wire.
- the luminous element is preferably held by heat-resistant holding means which can defy an arc, for example a solid wire frame or preferably glass webs, which are formed from the material of the bulb.
- the lamp according to the invention can be produced inexpensively, since little components are required and the production can be automated particularly well.
- the reflector lamp according to the invention is particularly suitable for direct operation at mains voltage, which should be understood to mean a range from approximately 80 V to 250 V. Typical wattages are 25 to 150 W. Due to its compactness, this lamp can be used for many applications (e.g. PAR lamps, aluminum-coated reflector lamps, cold light reflector lamps).
- FIG. 1 shows an exemplary embodiment of a reflector lamp
- Fig. 2 shows an embodiment of a reflector discharge lamp.
- the burner has a cylindrical piston 41 made of quartz glass with an outer diameter of approximately 13.5 mm with an inner diameter of 11 mm and a total length of approximately 38 mm (previously 86 mm).
- One end of the piston 41 is shaped into a dome 63 which has a pump tip 64 in the center.
- the other end of the piston is closed with a pinch seal 45.
- the flask is filled with an inert gas mixture of 80% Kr and 20% N 2 , to which a halogen addition of 0.005% CBrClF 2 is added.
- An approximately U-shaped lamp 56 made of tungsten extends over almost the entire inner length of the bulb volume, the base part 57 of the "U”, which extends transversely to the lamp axis, being arranged near the dome 63, while the Both legs of the "U", which form the actual luminous spiral sections 47, extend from the base part 57 to the pinch seal 45 and thereby open slightly towards the pinch seal 45.
- the ends of the two luminous coil sections 47 merge into short, approximately 4 to 7 mm long, uncoiled wire sections 59, which act as internal current leads with an inherent securing effect.
- the inner power supply lines 59 are melted into the pinch seal 45 over a short length (typically 3 mm or less) and welded there to sealing foils 60 made of molybdenum.
- the power leads 59 protrude a few millimeters (typically 3 to 5 mm) from the pinch seal into the piston volume.
- external power supply lines 50 are welded, which protrude beyond the end of the pinch seal 45. They are angled outwards and thread into bores 54 of contact pin sleeves 51.
- the sleeves 51 have cylindrical thickenings 52 at their end.
- the base part 57 of the "U" is not helical. It is arranged transversely to the lamp axis just below the pump tip 64. Its ends are angled by approximately 90 ° and each extend to a helical section 47.
- the helical design shown with two short parallel legs 47 which Standing close to each other has an advantageous effect on the light distribution in the reflector.
- the dimensions of the two spiral legs are approximately 0.5 x 9.5 mm.
- the luminous element is fixed by a single oval glass web 42, which is formed from the material of the cob. The base steep 57 is squeezed into the glass web 42.
- the piston has an overall length of only 38 mm, calculated from the pinch to the pump tip.
- the piston can therefore be accommodated in a very compact reflector 43 made of (hard) glass with an outer diameter of 50 mm.
- the reflector made of borosilicate glass has a base body 43, which is designed as a cathode and has a contour 66 on the inside, and a neck part 46 arranged thereon at the rear.
- the contour is coated with aluminum or a thin interference filter system. The latter has an advantageous effect as a cold light mirror.
- the reflector opening is closed by a cover disk 61.
- a resilient, slightly curved perforated disk 44 made of sheet metal is used, which rests on the piston at the level of the pinch 45. It has an opening adapted to the pinch and two guide tabs lying on the narrow sides of the pinch.
- the perforated disk 44 is seated on four elongated beads 67 arranged axially parallel (only two are visible in FIG. 1), which protrude from the neck 46 of the reflector.
- the piston is fixed without base putty by using the spring action of the perforated disc (similar to that described in DE-GM 195 48 521).
- the piston is inserted into the neck part under pressure and the outer power supply is then crimped onto the sleeve.
- the reflector tapers towards the end of the reflector neck 46 to an outer diameter of 20 mm.
- the total length of the reflector lamp is 49 mm.
- the reflector lamp has a glass base 48 which is directly molded onto the reflector neck. This essentially consists of a flat wall 49 at the end of the reflector neck, which acts as an integral Bottom part acts.
- the outer power supply lines 50 of the built-in lamp are guided outwards through two openings 53 and are threaded into the bores 54 of two metallic contact pin sleeves 51 seated in the openings 53.
- the bores extend over a partial length of the sleeve, the outer power supply 50 being crimped into the sleeve 51 (55) (alternatively, they are welded into a continuous bore).
- the contact pin sleeves 51 themselves are riveted into the openings 53 in that the inner edge 70 of the sleeve is bent over on the inner end face 71 of the wall and at the same time a disk-like collar 72 formed centrally on the sleeve rests on the outer end face 73 of the wall.
- the two contact pin sleeves 51 have a center distance of 10 mm.
- a fuse is usually provided between the reflector cap and base in the power supply system, which fuse is usually inserted into a separate intermediate part (using putty).
- the inner power supply is an uncoiled wire with a wire thickness of approximately 100 ⁇ m, as a result of which the inner power supply acts as an inherent fuse. This further reduces the overall length.
- two flat strip-like beads 58 are mounted opposite one another transversely (or longitudinally) to the two contact pin sleeves 51 on the outer edge of the outer end face 73.
- the thickness of the beads 58 is precisely matched to the thickness of the disk-like collars 72, so that their respective end faces remote from the piston together define a plane (as a kind of contact dimension).
- the thickness of the beads can also be chosen larger than that of the collar; however, this then extends the overall length of the lamp.
- the sockets have two elongated, slightly circular, slot-like openings (or recesses), at each end of which there is an enlarged circular opening for inserting the contact pin sleeves 51.
- the strip-like beads serve on the one hand as a spacer, so that the sleeves do not touch the bottom of the recess and therefore remain easy to move during the subsequent rotary movement.
- the collars cannot be inadvertently inserted into the enlarged opening of the socket, where they would jam when turned.
- the strip-like beads relieve the pressure on the cylindrical thickenings when the base is turned in the socket. This reduces the rotational resistance.
- FIG. 2 shows a reflector lamp 74 with a burner 76 designed as a metal halide lamp squeezed on one side, which is additionally insulated by an outer bulb. Instead of several strip-like beads, one (or more) annular bead 78 is attached to the outer edge of the wall 49.
- the transition between the neck part 46 and the outer end face of the wall 49 is not rectangular, but is conveyed by means of a radially circumferential bevel 75. All other properties of this lamp are similar to those of the incandescent lamp of the first exemplary embodiment and have the same reference numerals.
- the present invention has particular advantages over known reflector lamps, since both the number of components (now six components, previously ten components including the intermediate part) can be reduced and the assembly technology can be considerably simplified.
- the new product can therefore be manufactured much more cost-effectively, saves material and also saves time.
- the luminous element is arranged axially and only the power supply which leads to its end on the pinch side is melted into the pinch as an uncoiled wire section.
- the short luminous element is arranged either axially or transversely to the axis.
- the invention provides, in particular, an inexpensive reflector incandescent lamp with low power consumption down to 25 W or even less for direct connection to the mains (HV, MV), as used for general my lighting is of particular interest.
- Preferred power levels are a maximum of 250 W.
- the invention is particularly advantageous in the case of halogen bulbs with small wattage (up to 75 W) which are pinched on one side, since the cost and space-saving effect of the invention is most effective when using a glass base.
- the invention is not restricted to the exemplary embodiment shown. In particular, it is also suitable for halogen incandescent lamps for mains operation at 110 V. It is also suitable for other types of incandescent lamps or also discharge lamps.
