Abstract
The present invention discloses an illumination device for illuminating users of a multimedia communication terminal. In particular, the illumination device includes high power white LEDs together with a reflector and a diffuser integrated in, or connected to, the terminal. Preferably, the light intensity and the position and angle relative to the terminal are controllable through a user interface.
Claims9
An illumination device for illuminating one or more users in front of a multimedia communication terminal, comprising:
- a LED lamp assembly, comprising:
- a gutter-shaped housing with a generally angular or U-shaped cross section including a light reflecting material on an interior of a bottom member of the gutter-shaped housing,
- a LED array including a number of light emitting diodes attached to the interior of the bottom member of said gutter-shaped housing, and
- a diffuser sheet including a light diffusing, partly transparent material disposed on top of said gutter-shaped housing;
- and
- a user interface allows for control adjustment of a light intensity of at least one of the light emitting diodes and for control adjustment of a position or angle of the LED lamp assembly relative to the multimedia communication terminal, the user interface including a menu system, wherein
- said illumination device is configured to be attached under, above or on a side of the multimedia communication terminal by one or more retaining devices, and
- said LED array is configured to be electrically coupled to a power source controlled by the multimedia communication terminal.

A system comprising:
- a LED lamp assembly including a gutter-shaped housing with a generally angular or U-shaped cross section including a light reflecting material, a LED array including a number of light emitting diodes attached to a bottom of said gutter-shaped housing, and a diffuser sheet including a light diffusing, partly transparent material disposed on top of said gutter-shaped housing;
- a multimedia communication terminal configured to transmit signals through a network;
- a retaining device configured to attach the illuminating device to the multimedia communication terminal;
- and
- a user interface allows for control adjustment of a light intensity of at least one of the light emitting diodes and for control adjustment of a position or angle of the LED lamp assembly relative to the multimedia communication terminal, the user interface including a menu system,
- wherein said LED array is configured to be electrically coupled to a power source controlled by the multimedia communication terminal.
3 more elements
A system comprising:
- a LED lamp assembly including a LED array;
- a first multimedia communication terminal configured to transmit signals through a network;
- a retaining device configured to attach the illuminating device to the multimedia communication terminal;
- and
- a communications interface configured to receive a command through the network from a remote second multimedia communication terminal to adjust a light intensity of at least one of the light emitting diodes or to adjust a position or angle of the LED lamp assembly relative to the multimedia communication terminal.
