<p>PURPOSE:To make even the retention of supporter wires and increase the retaining strength by providing a car electrode whose base is mounted on a bulb body, equipping the base with a flange as a holding surface for a lighting fixture, and installing a pair of terminal parts of the body in parallel with this flange. CONSTITUTION:A bulb body 2 and a base 6 equipped with a flange 7 as a lighting fixture holding surface are installed in such an arrangement that the flange is approx. parallel with a pair of terminal parts of the body 2. Thereby supporter wires 8 have the same length and same shape between the body 2 and base 6, which increases the strength of holding the body 2. The coil axis Z of a filament 2a is put identical to the optical axis X of the rotary parabolic plane of a reflex mirror 11, and the filament 2a is positioned near the focus. Thereby mounting for obtaining good light distribution for a car lamp using a bulb body in the form of double end can be done without generating shortage of strength.</p> |
