Explosion protection system for a high pressure lamp

A high-pressure lamp and lamp cap technology, which is applied to the parts of gas discharge lamps, discharge lamps, discharge tubes, etc., can solve problems such as failure to effectively deal with reflector rupture, damage to the mechanical stress of the lamp, and inability to ensure protection.

Problems solved by technology

[0003] However, these protective measures have the following disadvantages. On the one hand, in the case of metal grilles, complete protection cannot be ensured because the entire lamp cap is not covered.
On the other hand, in the case of an additional cover, which is fixedly connected to the reflector, this can lead to breakage of the reflector and also of the protective cover.
Furthermore, in this case the materials used must have similar thermal properties, since otherwise mechanical stresses that can damage the lamp can occur
However, this means that only partially very unstable materials can be used, by means of which the breakage of the reflector cannot be effectively counteracted.

Embodiment Construction

[0021] In the following, identical or functionally similar elements are identified with the same reference numerals.

[0022] figure 1 A schematic diagram showing a first preferred embodiment of a lamp construction according to the invention. Such a lamp configuration has a discharge burner 2 which is surrounded by a reflector 4 and accommodated by a base 6 . The discharge burner itself has a discharge vessel or discharge bulb 8 filled with discharge gas, which is closed gas-tight by two sealing regions 10 and 12 , for example pinch regions. Embedded in the pinch regions 10 and 12 are electrodes 14 whose free ends project into the bulb 8 . In the pinch region 10 , 12 the electrodes are usually connected by a molten molybdenum film to the feed element 16 , 18 , wherein the feed element 16 is in electrical contact with the lamp cap 6 , while the feed element 18 is passed through the reflector 4 by a feed line 20 .

[0023] By applying a voltage between the electrodes 14 , an...

Abstract

The invention relates to a base for a high pressure lamp, said base having lateral walls enclosing the lamp bulb. The invention also relates to said lateral walls for a base and to a lamp system comprising said base.

Description

technical field [0001] The invention relates to a base for a high-pressure lamp and to a lamp design with such a base. Background technique [0002] High-pressure luminaires have lamp vessels filled with a gaseous medium. Especially during operation, pressures of typically several to several hundred bar occur within the lamp vessel. Furthermore, certain types of halogen incandescent lamps are involved, and in particular high-pressure discharge lamps. The latter has, for example, a discharge bulb with an anode and a cathode arranged therein, between which an electric arc is generated by a gas discharge during operation. Furthermore, there are also high-pressure discharge lamps for alternating current operation, ie with two identical electrodes, as well as discharge lamps without electrodes. For example with microwave excitation. In any case, the lamp vessel preferably consists of quartz glass or glass ceramics and is designed for this purpose to withstand pressures in par...
