Abstract

PURPOSE: To accomplish accurate starting along with smaller size and less weight through solid supporting of the fluorescent lamp and a lamp for limiting starting current with a common cap without use of stabilizer.
CONSTITUTION: A U-shaped fluorescent lamp 1a is solidly supported with a cap 3b, inside which a incandescent lamp 2 is housed. The fluorescent lamp 1a and the incandescent lamp 2 are electrically connected in series to the cap 3b. The fluorescent lamp 1a is provided with opposed electrodes 5 and 5 sealed on two ends of a tubular bulb 4. The space between the electrodes 5 and 5 is less 320 mm. The ratio of the space to the diameter of the bulb (the space divided by the diameter) is less than 14. The cap holds the lamp 2 in a light permeable base 6b while the fluorescent lamp 1a is fixed to one end thereof, and a connection 7 is provided at the other end. Accordingly, the input of the fluorescent lamp 1a is limited by the input characteristic of the lamp 2 thus allowing a better action.
