DE3136234C2 - Discharge lamp with adjusted radiation exit direction - Google Patents

Abstract

Discharge lamp, the bulb and base are immovably connected to one another. The base contains positioning holes so that a lamp that has been adjusted once can be used in any corresponding device without further adjustment.

Description

The positioning holes are in order to avoid confusion with different Cross-section formed

The drilling of the positioning bores and thus the actual adjustment is illustrated using the example of a discharge

& floor (Fig. 3) explained First the discharge lamp!, the bulb 2 of which is inserted into the base 3 without adjustment, is firmly connected to it. It is then attached and inserted into a hall device that is movable in all degrees of freedom in a dummy device - the holding device and the dummy device are for reasons of clarity - not shown
