摘要： PROBLEM TO BE SOLVED: To provide an incandescent lamp capable of achieving miniaturization by making a shape of a filament small, and also capable of sufficiently utilizing light distribution characteristics of a reflector in the case that the incandescent lamp is combined with the reflector. SOLUTION: In the incandescent lamp, a bulb 1 comprises a pinch seal part 11 formed on one end, and the residual part 12 of an evacuating tube formed on the other end, wherein a plurality of filament segments 20 forming the filament 2 are hung generally in parallel with the tube shaft inside the bulb 1. Each of the filament segments 20 is formed by being wound by an auxiliary filament wire 2b around a filament core wire 2a, wherein the filament core wire 2a is wound in a coil shape.

摘要： PROBLEM TO BE SOLVED: To provide an electric bulb and luminaire incorporating this electric bulb capable of reducing heat loss of a coiled-filament connected between lead wires at lighting and improving luminous efficiency. SOLUTION: This electric bulb L1 comprises a glass bulb 1, a double coiled- filament 4, inert gas and halogen. A sealing part 11 is formed on an end part of the glass bulb 1 whose internal diameter in a maximum diameter part (bd) is 14 mm or less. The double coiled-filament 4 is provided in the glass bulb 1 along a bulb axis wherein an outer diameter (fd) thereof is 1/8 or more of the maximum internal diameter part (bd) and a maximum temperature is 2500 deg.K or more at rated illuminating. The inert gas and halogen are sealed in the bulb 1. The electric bulb L1 is built into a reflex electric bulb and is fixed to a luminaire.
