A discharge lamp driving apparatus includes, a direct current power supply having a rectifier, an inverter circuit, which has stable and unstable output terminals, converting a direct current power to an alternating current power with a predetermined high frequency and driving a discharge lamp having a folded portion, a controller for being able to dim the discharge lamp, and an auxiliary conductor, arranged to the folded portion of the discharge lamp, and electrically connected to the stable potential output terminal of the inverter.
摘要:
A compact self-ballasted fluorescent lamp (10) which is equivalent to a typical light bulb is provided. The self-ballasted fluorescent lamp (11) induces a cover (14), a ballast (16), an arc tube (18), a base (12) and a globe (17) and formed into a shape whose outline dimensions are nearly identical to the standard dimensions of a typical light bulb. The arc tube (18) is comprised of a plurality of U-shaped bent bulbs (31) which have an inner tube diameter ranging from 6 to 9 mm and arranged in parallel with one another. Having a bulb height ranging form 50 to 60 mm and a discharge path from 400 to 500 mm, the lamp power is 16 to 23 W. An envelope (19) comprising the cover (14)and the globe (17) has a height ranging from 110 to 125 mm including the height of the base (12). As single lead wire (copper-weld) (54) is sealed with the pinch seal portion (45b,45c) at position away from the connecting tube (36) of the bulb (31), the thermal effect to which the copper-weld wire (54) is subject when connecting the tubular bodies (33a, 33b, 33c, 33d) with the connecting tube (36) is reduce and cracks generated on the pinch seal portion (45) which is the sealed point, as a result of the copper-weld wire (54) heated to a high temperature can be prevented and the yield can be improved.
