Problems solved by technology

The disadvantage is that the known fillings for discharge vessels which can produce such a color temperature contain very aggressive components
They can corrode the discharge vessel, in particular made of quartz glass, and can thus lead to an early end of service life

Embodiment Construction

[0043] figure 1 A gas discharge lamp 1 in the form of a metal halide vapor lamp is shown. The latter comprises a lamp cap 2 held in an outer bulb 4 . Furthermore, the gas discharge lamp 1 is configured to be built on one side with a base 6 .

[0044] The burner 2 comprises an approximately spherical or ellipsoidal discharge vessel 8 from which two axes 10 , 12 extend radially away. Two electrodes 14 , 16 are arranged inside the base 8 . These electrodes are connected to electrode connections 18 , 20 each guided through a shaft 10 or 12 . Each electrode connection comprises a part made of a molybdenum film and the sealing of the discharge vessel 8 can be carried out in the region of the two axes 10 , 12 by means of the glass clamping process common in the prior art. The current supply 18 , 20 is further led downstream of the respective shaft 10 , 12 between the outer bulb 4 and the lamp cap 2 to the base 6 . The latter comprises two electrical connections 22 , 24 for estab...

Abstract

The invention discloses a gas discharge lamp and a spotlight system comprising the gas discharge lamp. The gas discharge lamp comprises a bulb head which is enclosed by an outer bulb. In the outer bulb, samarium is provided.

Description

technical field [0001] The invention relates to gas discharge lamps. It is used in particular for the lighting of cinema projections and televisions, for display windows ("shop lights"), for theater lighting, for lighting of exhibition / warehouse halls and industrial halls, for stadium lighting, for architectural and Aquarium lighting, or for traffic and exterior lighting. Furthermore, the invention relates to a spotlight system comprising a gas discharge lamp. Background technique [0002] Halogen lamps emitting at a color temperature of about 3200K are known to be used in entertainment or studio lighting venues. Light of this color temperature is particularly advantageous for the site and will also play an important role in the future. A disadvantage in this context is that halogen lamps have a relatively low energy efficiency. [0003] Furthermore, energy-efficient gas discharge lamps are known in the prior art. These are for example halogen metal vapor lamps (eg OSRA...
