Problems solved by technology

There is a constant effort by users of such equipment to reduce cost prices to make the equipment cheaper, but the absence of such units would result in a lower quality of the equipment because, for example, the equipment would have a lower lumen output of
A disadvantage of the known lamp / reflector unit is that it is difficult to produce a high-quality reflector body by means of a relatively expensive manufacturing process

Embodiment Construction

[0025] exist figure 1 In the lamp / reflector unit there is a molded reflector body 1 provided with a reflector part 2 with an optical axis 4 and an outer surface 23 and a hollow neck part 5 which Part 5 is integrated with the reflector part 2 around the optical axis 4 . The reflector part 2 also comprises a concave, e.g. parabolically curved, reflective inner surface 3 between the neck portion 5 and an initially open light emission window 6 transverse to the optical axis 4 and Covered by a transparent plate 7. However, in alternative embodiments, the inner surface 3 may be eg elliptical. The reflector body 1 in the figure is made of glass-ceramic material and has a metal layer, such as an aluminum layer or a dichroic layer, which serves as the reflective inner surface 3 of the reflector body 1 . The reflector body 1 can also be made of, for example, glass, metal or synthetic resin. This unit also comprises an electric lamp 10 provided with a light-transmitting lamp vessel 1...

Abstract

The electric lamp / reflector unit has a molded reflector body (1) comprising a hollow neck-shaped portion (5). An electric lamp (10) having a lamp vessel (1), enclosing a space (12) in which an electric element (13) is arranged, and provided with a first (14) and a second, opposed end portion (15) is fixed at its first end portion (14) within the neck-shaped portion (5). At least one outer current conductor (16, 17) extends from the electric element (13) to the outer surface (23) of the lamp / reflector unit via a punched duct (25) in the reflector portion (2) of the molded reflector body (1). Said duct essentially extends in a direction transverse to the outer surface of the reflector body.

Description

technical field [0001] The invention relates to an electric lamp / reflector unit comprising: [0002] a molded reflector body provided with a reflector portion having an optical axis and an outer surface and a hollow neck portion integrally integrated with the outer surface about the optical axis; [0003] a concave reflective inner surface located between the neck portion and a light emission window transverse to the optical axis; [0004] An electric lamp provided with a light-emitting lamp vessel which is closed in a gas-tight manner and has a cavity in which electrical components are arranged, the lamp vessel also has mutually facing first end portions and Second end portions, each with a seal through which the respective first and second current conductors connected to the electrical component pass from the lamp vessel to the outside, passing through the conduit in the reflector portion will The second current conductor is led to the outer surface, and the electric lamp ...
