TUBULAR INCANDESCENT LAMP AND LAMP-INSTALLING PART STRUCTURE

Japanese Patent JP3829598

B2

PROBLEM TO BE SOLVED: To provide an installing part structure for which there is not mistaking in the installing direction of a tubular incandescent lamp, without having to increase the number of part items of the tubular incandescent lamp as well as to provide an installing structure of a tubular incandescent lamp for not braking the tubular incandescent lamp by torque by screw fastening, when installing the tubular incandescent lamp in a lamp device.
SOLUTION: This tubular incandescent lamp is a tubular incandescent lamp for arranging both conductive plate-like terminals connected to power supply led wires projecting from both ends of the lamp for arranging a filament along the tube axis of a bar-shaped tubular sealing body which are flush with each other including the tube axis; and is characterized in that both shapes of the plate-like terminals connected to the tubular incandescent lamp are of the same shape, a hole part or a cutout part is arranged on the tube axis of the tubular incandescent lamp on the plate-like terminals; and is of a bilaterally asymmetric shape with a virtual line passing through the hole part or the cutout part and orthogonal to the tube axis as a reference; and the direction of the plate-like terminals connected to one end of the tubular incandescent lamp is the direction for translating the plate-like terminals connected to the other end of the incandescent lamp along the tube axis.
