Abstract
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).
