Abstract
PURPOSE: To reduce the size and weight by lighting an electrodeless discharge fluorescent lamp with a battery cell.
CONSTITUTION: A cylindircal cover made of a transparent material is fittied into an opening of a case for packing battery cells connected in series to each other through an electrode plates 16 and 18 attached to the case 10 and electrode plates 17 and 19 attached to a cover 11. A steel-made support body 7 is fixed on a circular projection 20 formed on one of openings of the case 10 and a spherical bulb 1 is placed on the upper portion of the support body. The bulb 1 is supported with a circular rubber member 8. An oscillation coil 2 composing an electrodeless discharge lamp is inserted into a sunk tubular section 22 of the bulb 1 and generates an electromagnetic field to excite mercury. Both ends of the coil 2 are insertd into holes 25 and 26 on a circuit substrate 3 solidly constructed with a support bar 27 fixed on the bottom of a suport body 2. Numerous circular steel plates 5 are pro- vided in a space between the cover 9 and bulb 1 to shield the electromagnetic field generated from the coil 2.
