Abstract

The light has a reservation pot (3) including vertical blades (13) passing through interior of a circular space (11) filled with air. A lighting body (4) has exterior vertical blades (14) that pass through interior of the space and are inserted between the blades (13). The blades (13, 14) are distributed all around the periphery of the light to form a temperature reduction system at a level of a closing sheet (5). The circular space is defined between the reservation pot and a lateral wall (9) of the light body.
