Problems solved by technology

[0004] A disadvantage of such reflector lamps is that, on the one hand, the transmission and reflection properties of the metal specular reflector are defined over a wide spectral range, wherein the metal specular reflector is sensitive to light in the visible wavelength range and to light in the infrared wavelength range. The light has a high reflectivity and thus the thermal radiation mostly leaves the reflector lamp in the light exit direction
The coating process used to manufacture such reflector lamps is complex and costly due to the need for a protective layer

Embodiment Construction

[0031] The invention is explained below with reference to halogen reflector lamps using low-voltage technology with lamp sockets on one side, which are used in large numbers, for example, in general lighting. However, as mentioned at the outset, the reflector lamp according to the invention is by no means limited to this lamp type.

[0032] with the help of figure 1 First, a first exemplary embodiment of a reflector lamp according to the invention with an axial reflector is explained.

[0033] figure 1 Shown is a reflector lamp in the form of a low-pressure halogen reflector lamp 1 with a lamp vessel 4 made of quartz glass that is rotationally symmetrical about the lamp longitudinal axis 2 , in the lamp vessel 4 ( figure 1Middle) on the lower end section, a base 8 of type GY6.35 is formed via a shrink cap 6 , via which the halogen reflector lamp 1 can be inserted into a lampholder, not shown. The shrink cap 6 transitions via an approximately cylindrical lamp neck 10 into a ...

Abstract

Disclosed is a reflector lamp, particularly a halogen reflector lamp, comprising a translucent lamp receptacle in which at least one luminescent means is accommodated. At least one section of the lamp receptacle is provided with a reflective coating encompassing an interference filter which is substantially impermeable to light in the visible wavelength range while featuring a defined transmission and reflection behavior towards light in the infrared wavelength range.

Description

technical field [0001] The invention relates to a reflector lamp according to the preamble of claim 1 . Background technique [0002] In principle, the reflector lamp according to the invention can be used in various lamp systems. However, the main field of application of reflector lamps is to be found in halogen reflector lamps for general lighting, for example for ceiling-mounted or furniture-mounted luminaires, flexible lighting systems, signaling devices or radiators. [0003] Such a reflector lamp is known, for example, from DE 103 18 051 A1 of the applicant. Conventional halogen reflector lamps have a light-transmitting, one-sidedly sealed lamp vessel, which has a coiled filament arranged therein. In contrast to conventional reflector lamps, in the case of such a halogen reflector lamp, the vessel section of the lamp vessel is provided with a light-reflecting coating. In this solution, the light-reflecting coating is designed as a metallic coating made of aluminum o...
