Definitions

  • the invention relates to a reflector lamp according to the preamble of the claim 1.
  • Such a reflector lamp is, for example, in the European patent application EP 0 780 884 A1.
  • This document discloses a lamp-reflector unit with a metal spring attached to the lamp and on Reflector is resting. With the help of this metal spring under mechanical tension the lamp is fixed in the reflector.
  • This reflector lamp is around a pin base lamp.
  • the metallic holder of the reflector lamp according to the invention is non-rotatable in arranged on the reflector neck and so on the reflector neck and on the base sleeve matched that the holder and the base sleeve when mounting the reflector lamp by the interaction of the metallic holder with the thread of the Base sleeve and with the help of the depth stop arranged in the reflector neck for fix the metallic holder to each other.
  • the depth stop prevents axial movement of the holder.
  • the base sleeve is based on the Screw on the metallic holder on the outer wall of the reflector neck.
  • the outer wall of the reflector neck forms a stop surface for the base sleeve and thus serves as a counter bearing to the depth stop on which the metallic holder rests.
  • the metallic holder offers through its Contact with the inner wall of the base sleeve an easy way to electrical Contacting the lamp.
  • the non-rotatable arrangement of the metallic holder in the reflector neck is advantageously ensures that both the shape of the opening in the reflector neck and the one arranged in the opening in the reflector neck Section of the metallic holder have a shape with respect to the reflector axis is not rotationally symmetrical, and the dimensions of the opening and of the section of the metallic holder arranged in the opening are coordinated.
  • This can be implemented in a simple manner in that the section of the metallic arranged in the opening of the reflector neck Holder is designed as a sleeve, the at least two opposite one another and has parallel side walls, and the reflector neck in Area of its breakthrough at least two opposite inner walls has against which the parallel side walls of the sleeve abut.
  • the metallic holder In order to fix the metallic holder in the reflector neck, it is advantageous provided with at least two brackets angled perpendicular to the reflector axis, that rest on the heel of the reflector neck designed as a depth stop.
  • the part of the reflector neck protruding from the opening in the reflector neck arranged section of the metallic holder is advantageous provided with knobs that lie against the inner wall of the base sleeve and into the Grip the thread of the base sleeve. These knobs form one on the thread of the Base sleeve matched thread and thereby enable a screw connection between the base sleeve and the metallic holder.
  • the outer contour is to ensure the arrangement of the base sleeve on the reflector neck of the reflector neck advantageously with an oblique to the reflector axis Surface.
  • the base sleeve is advantageously with the help an adhesive or crimped to the reflector neck to loosen it the screw connection between the base sleeve and the metallic holder prevent.
  • the metallic holder advantageously also becomes an electrical one Contacting used. For this purpose, one of the protruding from the lamp Power leads electrically connected to the metallic holder. This makes this power supply with the thread of the base sleeve electrical contacted, while the other power supply with the ground contact of the base sleeve is electrically connected.
  • FIG. 1 shows a side view of the preferred embodiment of the invention Reflector lamp in a partially sectioned representation.
  • This reflector lamp is intended for operation on the mains voltage and has an electrical one Power consumption of approximately 40 watts. It essentially consists of one Reflector 10, a halogen incandescent lamp 20, which is by means of a metallic holder 30 is fixed in the reflector 10, and from an E14 screw base for power supply the lamp 20.
  • the E14 screw base is from the one with the thread 41 provided metallic base sleeve 40, the base stone 42 and the ground contact plate 43 formed.
  • the reflector 10 is rotationally symmetrical with respect to it Axis A-A is formed and has one by means of a translucent disk 11 covered light exit opening and a reflector neck arranged diametrically to it 12 on.
  • the reflector neck 12 is hollow and, with the exception of its end, rotationally symmetrical educated. Its inner wall is towards the end of the reflector neck conically tapered. The taper is 3 degrees to the reflector axis A-A.
  • the reflector neck 12 has at its opposite the light exit opening End of a breakthrough that deviates from the rotational symmetry 14. This opening 14 is laterally by two opposite, flat inner walls 15 and by two opposing arched inner walls 16 limited.
  • the Inner walls 15 are the opening of the reflector neck 12 in the area of the opening 14 with respect to the cavity 13 of the rotationally symmetrical trained part of the reflector neck 12 narrowed step-like.
  • the Inner walls 15 therefore each form a shoulder within the reflector neck 12 17, which is angled as a depth stop for four perpendicular to the reflector axis A-A Tabs 31 of the metallic holder 30 is used.
  • the two inner walls 15 slightly wedge-shaped, so that the opening 14 in the direction the end of the reflector neck 12 is narrowed.
  • the halogen incandescent lamp 20 is axially aligned in the reflector 20. It is by means of of the metallic holder 30 in the opening 14 of the reflector neck 12 attached.
  • the one-piece metallic holder 30 has two Brackets 32, the sealed squeeze foot 21 of the lamp 20 with a press fit enclose, and a portion 33 formed as a sleeve, which with a clamp fit in the opening 14 is arranged and partially from the end of the reflector neck 12 protrudes.
  • the section 33 of the metallic holder 30 designed as a sleeve consists of two mutually opposite, parallel planes Sidewalls 33b and two other, opposing arched Sidewalls 33a.
  • the sleeve 33 thus has a plane perpendicular to the reflector axis A-A has a square cross-section, although the two end faces of this Quadrilaterals are arched.
  • the two curved side walls 33a of the sleeve 33 are each equipped with an outwardly protruding knob 34 on the inner wall of the base sleeve 40 and engage in its thread 41. These pimples 34 form part of a thread, so that the base sleeve 40 by a Screw connection can be connected to the sleeve 33 or to the metallic holder 30 is.
  • the two flat side walls 33b of the sleeve 33 lie on the wedge-shaped extending inner walls 15.
  • a first power supply wire 22 is with a curved side wall of the sleeve 33 by a welded connection electrically connected.
  • the other power supply wire 23 is non-contact arranged with respect to the metallic holder 30 and with the ground contact plate 43 electrically connected.
  • the base sleeve 40 is additionally crimped 44 at the end of the Reflector neck 12 fixed to loosen the screw connection between the metallic Prevent holder 30 and the base sleeve 40.
  • a play-free arrangement to ensure the base sleeve 40 on the end of the reflector neck 12, is the outer contour of the reflector neck 12 with an oblique to the reflector axis A-A provided running surface.
  • the base sleeve 40 is step-like in the direction of its opening extended.
  • the resulting paragraph 45 uses the end of the reflector neck 12 as a stop surface 19.
