Abstract

A lamp includes at least one luminous source (14, 6, 8), in particular a low-pressure discharge lamp, for producing main illumination and having at least one alternative luminous element (22), in particular a light-emitting diode arrangement having at least one LED, for producing alternative illumination, which are arranged on a cap (12) , and having electronics, wherein a switching arrangement, which can be actuated manually, for operating the lamp in the main illumination mode, the alternative illumination mode or in both illumination modes at the same time is provided in the cap.

Claims

1. A lamp comprising a plurality of discharge tubes, for producing a main illumination, arranged on a base cover of a base, and with at least one light-emitting diode arrangement with at least one LED, arranged on a dome that extends from the base cover of the base up to a region below a connection of the plurality of discharge tubes, for producing an alternative illumination, and with electronics, wherein a manually actuable switching arrangement for operating the lamp in the main illumination mode, alternative illumination mode or in both illumination modes at the same time is provided in the base.

2. The lamp as claimed in claim 1, the switching arrangement having a slide for producing an electrical connection between an electrical line of the electronics and at least one contact element of the light source or the alternative luminous means.

3. The lamp as claimed in claim 2, the electrical line being connected to the slide in such a way that a line section which extends in the sliding direction and can be brought to rest directly at least against one of the contact elements is formed.

4. The lamp as claimed in claim 2, the slide having two opposite narrow sides, on which in each case one projection for actuating the slide is formed, which projection extends through a recess in the base.

5. The lamp as claimed in claim 4, the recesses being formed diametrically with respect to one another in the base cover.

6. The lamp as claimed in claim 5, switching positions of the slide being defined by end faces running onto an inner circumferential section of the base cover in the region of the recesses.

7. The lamp as claimed in claim 2, the alternative luminous means being arranged on a dome, which extends through the base cover and has an extension with two opposite cutouts for passing through the slide, the contact elements being arranged in a corner region of the cutouts.

8. The lamp as claimed in claim 1, the light source having a discharge vessel.

9. The lamp as claimed in claim 2, the light source having a discharge vessel.

10. The lamp as claimed in claim 3, the light source having a discharge vessel.

11. The lamp as claimed in claim 4, the light source having a discharge vessel.

12. The lamp as claimed in claim 5, the light source having a discharge vessel.

13. The lamp as claimed in claim 6, the light source having a discharge vessel.

14. The lamp as claimed in claim 7, the light source having a discharge vessel.
