Abstract
PURPOSE: To install a stabilizing circuit component easily affected by heat as compared with a starting circuit component at the position apart from a lamp by arranging a circuit board fitted with the starting circuit component on the lamp side, and arranging a circuit board fitted with the stabilizing circuit component on the base side.
CONSTITUTION: A circuit board 14 fitted with a starting circuit component 12 is fixed to the upper face of the partition board 5 of a closing member 4, and another circuit board 16 fitted with a stabilizing circuit component 13 is fixed to a support rib 19 apart from the circuit board 14 in the axial direction. The circuit board 14 fitted with the starting circuit component 12 is installed near a lamp 21 side in a cover 1, and the other circuit board 16 fitted with the stabilizing circuit component 13 is installed near a base 3. The other circuit board 16 fitted with the stabilizing circuit component 13 easily affected by heat is located at the position apart from the closing member 4, e.g. apart from the lamp 21, thereby the thermal damage of the stabilizing circuit component 13 is prevented.
