Abstract

The invention relates to a room lamp (1) which is designed to light a space under different angles and in a controlled manner, and which comprises—a plurality of different light emitting elements (122); and—a first illumination body (100) with a plurality of light directing devices at each of which a light emitting element (122) is arranged, each light emitting element emitting light in a light-guiding direction. At least one light directing device (102, 104, 106, 108, 110, 112, 114) has a collimation portion (124), in which the light rays of the light emitting element (122) that is arranged in the light directing device are parallelized, and a plurality of prism portions, each of which deflects a part of the parallelized light rays (126, 128, 130). The invention also relates to a method comprising the following steps:—controlling, by way of a gesture on a touch-sensitive display screen of a portable electronic device, the size and/or color and/or brightness of at least one area to be lighted;—detecting the orientation of the portable electronic device and of the room lamp; and—transmitting to the room lamp the size and/or color and/or brightness of the area to be lighted depending on the orientation of the portable electronic device and/or of the room lamp.

3. The room lamp according to claim 2, wherein the inclined areas of a light directing device each comprise a different angle with respect to an imaginative plane.

4. The room lamp according to claim 2, wherein a prism portion extents across a plurality of light directing devices and the inclined portion along the prism portion comprises along the same angle with respect to an imaginative illumination area.

5. The room lamp according to claim 2, wherein a plurality of prism portions and/or a plurality of light directing devices is arranged concentrically.

6. The room lamp according to claim 2, wherein a plurality of light directing devices is arranged linearly.

7. The room lamp according to claim 2, wherein each light directing device comprises one to five prism portions, preferably two to four prism portions.

8. The room lamp according to claim 2, wherein the inclined portions of the prism areas of a light directing device are inclined into the same direction.

9. The room lamp according to claim 2, wherein the first illumination body is formed integrally.

10. The room lamp according to claim 2, wherein the light emitting element is a light-emitting diode.

11. The room lamp according to claim 2, wherein the light emitting element is at least partially arranged in the light directing device.

12. The room lamp according to claim 2, whereby the light emitting elements having different colors are arranged adjacent in the light directing devices, wherein the inclined portions of the adjacent light directing devices, each have the same angle respectively.

13. The room lamp according to claim 2, wherein the first illumination body emits light in a downward direction, whereby the room lamp comprises a second illumination body which emits light in an upward direction.

14. A method for controlling the light output of a room lamp, comprising the steps of:

controlling of the size and/or the color and/or the brightness of at least one area to be illuminated by a gesture on a touch-sensitive screen of a operating device;
