- a partial area can be illuminated brighter by the room light, the faster it is painted over a partial area 306 on a touch-sensitive screen or this partial area 306 is touched.
- a subarea can be illuminated the brighter, depending longer and / or the more touches a sub-area 306 of the touch-sensitive screen and / or wiped over this.
- the illumination of an area to be illuminated can be reduced by touching a deletion symbol 304 and then touching the area 306 whose illumination is to be reduced.
- On the user interface third symbols can be arranged, by means of which the
- a slidable icon 308 may be displayed on the touch-sensitive screen, by means of which the illumination of the room lamp as a whole may be increased or decreased.
- the user interface shown in FIG. 13 can be used both for controlling the
- Light emitting diodes 204 are used on the second luminous 200. It can also be controlled several room lights These can be two different
- Color temperatures are displayed.
- the user can change the light output and / or the color of the light emitted by the room lamp by touching a desired color temperature or desired color.
- the room lamp comprises a transmitting and receiving device 192 (see FIG. 1) with which the information about the partial areas to be illuminated, the color temperature and / or the color output are received. Further, the orientation of the mobile electronic device is transmitted to the user interface for controlling the light output.
- the orientation determining device of the mobile electronic device may be a compass.
- the room lamp comprises an orientation determination device 194, for example a compass.
- the receiving device 192 to transform the data on the subregions to be illuminated in the coordinate system of the room lamp and drive the corresponding light-emitting diodes.
- the room light transmits via the transmitting and receiving device 302, the orientation of the room lamp 200 relative to the mobile electronic device.
- the mobile electronic device adjusts a representation of the area to be illuminated to the transmitted orientation.
- the data can be transmitted over an IP network, Bluetooth or any other network (NFC, near field communication).
- additional information about the duration of wireless signals can be determined, for example, the orientation and / or position of the mobile electronic device.
- FIG. 15 shows a section through a room lamp 1 according to the invention.
- the room lamp is attached by means of a cable 22 to the ceiling. It is understood that the room lamp can be attached to any other lamp stand.
- the first light emitting diodes 122 are directed downward and the second light emitting diodes 204 arranged upward.
- the first light emitting diodes 122 are arranged on the first luminous element 100.
- the diffuser 150 is arranged below the first luminous body 100.
- the second light emitting diodes 104 of the annular light guide body 208 is arranged.
- Control electronics are arranged outside of a capsule 26.
- a housing with cooling fins 24 is arranged to the capsule 26.
- the present invention has the advantage that a compact room lamp with an appealing design can be created, which makes it possible to illuminate a room both directly by means of the first filament and indirectly, for example via the ceiling, by means of the second filament.
- a user can change a desired angle pattern and a desired lighting strategy in operation without mechanically changing the room lamp.
- the lighting strategy may vary depending on the application, for example, a different lighting strategy may be used for eating than during the television.
- the color and the color temperature can be changed easily.
