Abstract

A lighting apparatus, in particular a reading lamp, is provided. The apparatus can be recessed in a trim of a passenger cab of a vehicle, which can be a land vehicle, an aircraft, or a watercraft. The apparatus has a first light-emitting device that is pivotably mounted to a recess-mounting frame, so that a light-emitting direction of the first light-emitting device with respect to the recess-mounting frame is changeable. To simplify the design of the apparatus, a second light-emitting device is mounted to a visible side of the recess-mounting frame. The second light-emitting device at least partially surrounds the first light-emitting device and is fitted to the recess-mounting frame, so that the light-emitting direction of the second light-emitting device is invariable.

First claim

What is claimed is:

1. A lighting apparatus mountable in a trim of a passenger cab of a vehicle, the lighting apparatus comprising:
a first light-emitting device pivotably mounted to a recess-mounting frame so that a light-emitting direction of the first light-emitting device with respect to the recess-mounting frame is changeable, wherein the recess-mounting frame comprises a visible side, and
a second light-emitting device, wherein the second light-emitting device at least partially surrounds the first light-emitting device and is fitted to the recess-mounting frame so that the light-emitting direction of the second light-emitting device is invariable.

2. The lighting apparatus according to claim 1 , wherein the second light-emitting device comprises a ring and surrounds the first light-emitting device.

3. The lighting apparatus according to claim 1 , wherein the first light-emitting device comprises at least one first LED and a controller for selectively controlling at least one of a brightness and a color of the light generated by the first LED.

4. The lighting apparatus according to claim 1 , wherein the second light-emitting device comprises at least one transparent light output means having a light output surface and a light input surface.

5. The lighting apparatus as claimed in claim 4 , further comprising at least one second LED, which is different the first LED, for inputting light into the light input surface.

6. The lighting apparatus as claimed in claim 5 , wherein the second LED is coupled to the light input surface by means of at least one fibreoptic conductor for light input.

7. The lighting apparatus as claimed in claim 4 , wherein the light output means comprises a ring or at least one ring segment.

8. The lighting apparatus as claimed in claim 4 , wherein at least one of the light output surface and an opposite rear surface is spherical.

9. The lighting apparatus according to claim 1 , wherein said lighting apparatus comprises a reading lamp.

10. The lighting apparatus according to claim 1 , wherein said vehicle is a land vehicle, an aircraft or a watercraft.

11. A vehicle comprising at least one lighting apparatus according to claim 1 , wherein the at least one lighting apparatus is recessed into a trim of a passenger cab of the vehicle,
wherein the first light-emitting apparatus, for the supply of current, is connected to a cab current supply system and the second light-emitting apparatus, for the supply of current, is connected to an emergency current supply system, which can be operated independently of the cab current supply system.

12. The vehicle according to claim 1 , wherein said vehicle is a land vehicle, an aircraft or a watercraft.
