The invention relates to an optical radiator, especially for ultraviolet or infrared radiation, with a lamp bulb socketed without cement on one end, from which at least two connecting wires are brought through pinches, one at the top and the other at the bottom of the lamp bulb, the first connecting wire being affixed at the upper end of the lamp bulb to a stiff support bow, and the lower end of the stiff support bow being brought as a terminal pin through a first bore in a lamp base and is fastened to the latter by an anti-extraction lock. The invention is addressed to the problem of offering an optical radiator which can be made quickly and at low cost from a minimal number of parts. The problem is solved in that the second connecting wire at the bottom end of the lamp bulb is carried loosely through a second bore in the lamp base.

Optical radiator with anti-extraction lock

An optical emitter is provided, in particular for ultraviolet or infrared radiation, with a lamp bulb (1) from which extend at least two connecting wires (4, 5) for electrical connection, in each case through a stem press (2, 3) at the upper end and the lower end of the lamp bulb (1). The first connecting wire (4) is electrically connected with a first contact pin (15) via a flexurally rigid holding bracket (6), and the second connecting wire (5) is electrically connected with a second contact pin (16) via a metallic contact element (7). The contact pins (15, 16) each extend out from a bore of a ceramic base (10). To provide an improved optical emitter which can be manufactured with lower expenditures of time and cost, the holding bracket (6) and the first connecting pin (15) are designed in one piece and the first contact pin (15) is provided with an anti-slip safety on both sides of the first bore in the base (10).
