Abstract (en)
[origin: JPH05198288A] PURPOSE: To improve utilization efficiency of a reflecting surface of an illuminating lamp. CONSTITUTION: An illuminating lamp 1 is composed of a reflecting member 3, a glass cover member 2 and a filament 5 supported by a pair of feeder lines 4. The feeder lines 4 are introduced from outside into the illuminating lamp 1 through a joining area of the reflecting member 3 and the glass cover member 2. Since a socket to receive an electric lamp, a part to arrange a passage of the feeder lines or the like are not used, a reflecting surface is not intercepted at all, and the light source light from the filament can be substantially reflected with efficiency of 100%.
