Method and device for generating optical radiation by means of electrically operated pulsed discharges

SUBMERSIBLE LIGHT

The invention relates to a submersible light, in particular for a swimming pool, comprising an elongated profiled inner housing into which an LED strip having a plurality of light-emitting diodes is inserted, and an elongated profiled outer housing into which the profiled inner housing is inserted, an inner region of the profiled outer housing between the end thereof and the associated end of the profiled inner housing being filled with a cured potting compound on both ends of the arrangement of the inner and profiled outer housing. The invention also relates to a method of making a submersible light. FIG. 3.

Method and device for generating optical radiation by means of electrically operated pulsed discharges

The present invention relates to a method and device for generating optical radiation (18), in particular EUV radiation or soft x-rays, by means of electrically operated discharges. A plasma (15) is ignited in a gaseous medium between at least two electrodes (1, 2), wherein said gaseous medium is produced at least partly from a liquid material (6), which is applied to one or several surface(s) moving in the discharge space and is at least partially evaporated by one or several pulsed energy beam(s) (9). At least two consecutive pulses (16) are applied within a time interval of each electrical discharge onto said surface(s). The delay between and/or the pulse energy of said consecutive pulses is controlled to stabilize the position of an emission center of the plasma (15).
