Definitions

  • the invention relates to a reflector lamp according to the preamble of the claim 1.
  • Such a reflector lamp is known for example from EP-A 572 400. It is an incandescent lamp, the base of which is partially through an insert part is formed at the end of the neck part of the reflector. This insert part must be connected to the neck part of the reflector using putty. Disadvantages of this base are that it is complex to manufacture and not is particularly precise. In addition, this construction leads to a Extension of the length of the reflector lamp, since space is required to to hold the insert part below the piston in the neck part.
  • US Pat. No. 4,797,794 describes a reflector lamp with a pin base. in which the thin contact pins are supported by a support part attached to the Reflector neck is molded, is supported, so that the overall length is significantly extended is.
  • the particular value of the invention is that the manufacture of the lamp is considerably simplified and at the same time the possibility is created to make the lamp more compact and in particular also continue to ensure high operational safety of these lamps.
  • the reflector lamp according to the invention has considerable cost and process advantages compared to the state of the art.
  • a particular advantage is that the concept of the integrated base allows to design the power supply system so that there are no contact problems due to contact resistance, which are common in Low voltage range (below 80 V) due to small contact areas with electrical Connections occur. Age-related corrosion causes the high contact resistance, the voltage drops in the leads to Consequence. The lamp itself is then significantly less in operation Tension.
  • the reflector lamp with a base on one side is characterized by the following Features from: a hermetically sealed piston with a filling and a lamp, a reflector, consisting of a reflector contour load-bearing basic body and a rear attached Neck part, a base that attaches to the neck part, and the two or more metallic ones Contact pins with cylindrical thickening at the end remote from the piston has, and a power supply system that has an electrical lead for the illuminant.
  • the base is completely out of the Material of the neck part formed and as an integral part directly on the neck part of the Molded reflector.
  • the bulb is normal in the reflector lamp according to the invention a separate piece of tempered glass or quartz glass inside the reflector that is squeezed in particular on one or two sides.
  • the piston is formed by the reflector itself, wherein the reflector has a hermetically sealed cover plate (sealed Beam technology).
  • the reflector lamp is equipped with a reflector made of glass, however temperature-resistant plastic is also suitable. Have these materials much better dimensional stability and tighter tolerances than ceramic Materials so that the base in the socket is better and more precise sits. Ceramic is also more expensive and heavier.
  • the invention relates to high-voltage or medium-voltage lamps, So lamps for an operating voltage of at least 80 V. So far to strongly desire the compactness of suitable reflector lamps left.
  • the base is made of a flat wall with an inner one 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 advantageous as contact pin sleeves with an inner bore formed, wherein the bore in the sleeve is at least over a part the sleeve length or extends over its entire length.
  • the attachment of the contact pin sleeves can be done easily take place that the sleeves on the piston side an outwardly bent edge and have a disc-shaped collar in the middle of the sleeve length, between which the wall of the base is locked.
  • a particularly interesting application for general lighting is a reflector lamp in which the lamp has an incandescent lamp a bulb squeezed on one side, which is a luminous body and inner Contains power supplies, the power supplies are designed so that they have an inherent security effect.
  • the inherent securing effect is particularly advantageous as follows Realized:
  • the inner power supply lines connect the ends of the filament with sealing foils embedded in the pinch and are over part of their length embedded in the bruise, with at least one the power supply consists of an uncoiled wire.
  • the inherent security effect achieved by at least one of the two inner power supplies from a wire with a diameter of at most 130 microns, preferably at most 80 microns, is made of the a length of at least 2 mm is embedded in the pinch, whereby the distance d between the power supplies and the applied voltage V cooperate so that in the event of a between the power supplies occurring arc the field strength V / d greater there than 100 V / cm, and is preferably between 200 and 400 V / cm. Closer Details can be found in DE-GM 296 07 132.
  • a specific advantage of a coiled wire compared to one Single helix lies in the fact that the mass of the power supply formed from it with the same length embedded in the pinch, considerably less is. The evaporation of the wire material in the capillary continues therefore much faster. The arc goes out earlier and that The response time of the inherent fuse is much shorter than that of others Fuses. In addition, the energy introduced into the arc is considerable smaller.
  • uncoiled wire also means a wire which was originally simply spiraled, but which was drawn out has been created, so that an elongated spirally wound wire is formed.
  • the pitch is typically 10 to 100 times the wire diameter.
  • the wire does not yet have its original spiral shape lost, but the turns are so far apart that no more tube-like cavity when squeezing.
  • the really housed This means that the wire length is significantly longer than that of a completely uncoiled one Piece of wire where the really housed wire length is identical to the pinched wire length.
  • the inner power supply preferably has a diameter of more than 15 ⁇ m.
  • the filament and the internal power supply can be made as a unit from a single wire, i.e. the inner Power supplies are the uncoiled filament ends.
  • the inner Power supplies are the uncoiled filament ends.
  • the wall is normal attached at right angles to the neck part.
  • the base can also be designed in this way be that the neck part by means of a radially circumferential bevel in the flat wall merges.
  • a particularly elegant option to do without a wire frame consists in that, in a manner known per se, at least one heat-resistant Holding means fixed the filament.
  • a high degree of compactness is particularly difficult with MV or HV lamps to achieve, since they are normally operated with a fuse. there the operating voltage is at least 80 V.
  • the power supply system therefore advantageously has internal power supply lines which are designed in such a way that they have an inherent security effect.
  • the filament With the incandescent lamps pinched on one side, the filament can be arranged axially or be bent into a U, V or W shape.
