摘要

The device has a lamp area (5) limited upward by a baseplate (2) laterally by a circulating casing (8) and downward by a curved trough shaped cover (24). The casing is spaced apart from the baseplate via feet (9) to allow air to flow into lamp area. Multiple air outlet openings (12) are formed in the casing's top edge. Multiple supporting elements (15) are attached to the casing to hold an outer casing (16) at a distance from the casing. Multiple air circulation improving devices are arranged in the lamp area and between the casing and the outer casing, and in the outer casing's top edge.
