<p>The design is based on the fact that in the light panel with a circumferential frame structure, the LEDs (1) are arranged on the internal side of the circumferential frame structure (2) with light emanating in at least one illumination plane (G) parallel with plane (H) of the transparent cover (3). Essential features of the invention also include the arrangement of LEDs (1), which are installed in rows or separate LED modules either along the entire circumference on the internal side of the circumferential frame structure (2) or only on a part of the internal side of the circumferential frame structure (2). Depending on the requirements placed on the light panel, LEDs (1) may emit white light or monochromatic light. To increase the efficiency of emphasising the colours of the transilluminated motive, e.g., an advertising poster, LEDs may be substituted with separate RGB-type LED modules. At the same time, this enables creating static or dynamic light effects using a control module (not illustrated).Separate RGB LED modules may also be provided with diffusers.</p> |
