Luminaire

Abstract

The invention relates to a luminaire comprising a housing, at least two radiation sources and at least one directing means. The directing means is used to direct the emission of electromagnetic radiation emitted by the radiation sources. According to the invention, the radiation sources are all located in the center of the directing means such that the radiation sources are arranged concentrically with respect to one another. The radiation sources can be switched on and off individually, jointly, or in combination. Each radiation source emits electromagnetic radiation within a constant wavelength range when switched on, wherein different radiation sources can emit electromagnetic radiation within different wavelength ranges.

Description

(1) Further features result from the attached drawings. In the drawings:

(2) FIG. 1: shows a directing means of the luminaire according to the invention having two radiation sources;

(3) FIG. 2: shows a detailed view of the carrier of the radiation sources from Figure one.

(4) FIG. 1 shows a reflector as a directing means 3 of the luminaire according to the invention, wherein the reflector is constructed like a truncated cone. The side on which the truncated cone tapers is the position on which the radiation sources 5, 6 are located.

(5) In the present case, the radiation sources 5, 6 are applied to a carrier 4, wherein a first radiation source 5 is arranged centrally, as seen from the directing means 3, and the second radiation source 6 is arranged concentrically around the first radiation source 5. The directing means is preferably arranged in the housing of the luminaire by means of a tolerance compensation 2. In this case, the tolerance compensation can be arranged on a transparent disk of the luminaire head. For this purpose, the tolerance compensation can also act as a seal.

(6) In this embodiment, the enclosure 1 is part of the housing of the luminaire and terminates with the transparent disk.

(7) The directing means 3 ensures the directional emission of the electromagnetic radiation from the radiation sources 5, 6. For this purpose, the reflector can be equipped with a smooth surface that can reflect electromagnetic radiation. Furthermore, it is possible to provide the surface of the reflector with a structure or with retro reflectors. This embodiment makes it possible to influence the emission characteristic of the weapon luminaire.

(8) FIG. 2 shows the arrangement of the radiation sources 5, 6 from the previous figure in detail. For this purpose, it is shown that the radiation sources 5, 6 are arranged on a carrier 4, wherein at least one of the radiation sources 5 is arranged on a base 8.

(9) In this case, the first radiation source 5 is composed of only one lighting means, preferably an LED. In this embodiment, the second radiation source 6 is composed of a plurality of lighting means, in this case four identical lighting means, which are arranged concentrically around the first lighting means 5.

(10) The second lighting means 6 can also be designed as LEDs, preferably from lighting means that emit thermal radiation, for example IR radiation.

(11) More than two different radiation sources 5, 6, 7 are also possible; in FIG. 2, for example, three different radiation sources 5, 6, 7 are shown. The radiation sources 5, 6, 7 are arranged concentrically to one another; in this case, the radiation sources 6, 7 are arranged concentrically to the radiation source 5. The second radiation source 6 and the third radiation source 7 are arranged alternately with respect to one another. The radiation source 7 is also arranged on the carrier 4.

(12) The different radiation sources can in each case be activated or deactivated independently on one another, preferably by means of a switching possibility 9 on the weapon luminaire. Likewise, the radiation sources can be switched on or off dependently of one another.

(13) The present invention is not limited to the above mentioned features, but rather further possible embodiments are conceivable. Thus, the reflector with the radiation sources is preferably accommodated in a lamp head that is rotatably mounted on the luminaire. By rotating the lamp head, however, the radiation source is not selected, as is known from the prior art, but the focusing is changed by changing the distance of the directing means from the radiation sources. Furthermore, radiation sources in the UV range are also conceivable, as well as laser sources for the purpose of target marking.
