The lamp reflector is formed from four segments (9,11,14,16) forming two half-reflectors. The segments are formed as surfaces of revolution, based on a spiral. One is larger than the other, and the two halves are joined by a strip (10,15) forming a step between the edges of the two halves. Ventilation slots are provided at the other two joints (12,17) between the two halves. |
