技术功效语段：
The present invention relates to a lighting device with a plate-shaped base body that has a hydrophilic and antibacterial coating, and a cooling element with cooling ribs that prevent clogging. The lighting device is designed to be simple, compact, stable, and easy to maintain and clean. It also has a holding or supporting element for attaching a light source, and a support frame element for holding optics. The design of the plate-shaped base body ensures that dust, dirt, or other contaminants cannot remain on its surface, and water or similar media can be easily removed. The invention provides a cost-effective and efficient solution for lighting up large spaces.
