。Problems to be Solved by the Invention However, since conventional light bulbs have an infrared reflective and visible light transmitting film formed on the surface of the bulb, even if the infrared rays from the filament are reflected by the infrared reflective and visible light transmitting film, the reflected light is not reflected. It was difficult to effectively return the infrared rays to the filament. In other words, for example, light bulbs such as general lighting bulbs currently used in homes have the shape of a bulb.
On the other hand, the filament is arranged with a length of 20 mm at the center of its maximum diameter, and the positional relationship between the two means that the infrared rays from the filament can be returned to the filament by the infrared reflective visible light transmitting film formed on the bulb. It is difficult.

に戻すことができる。The working filament is installed along its axis inside a glass tube with a film that transmits visible light while infrared rays formed on its surface.Visible light emitted from the filament is transmitted through the membrane, while infrared light is transmitted through the membrane. It can be easily reflected back into the filament.

A cylinder 4 is provided. The filament 5 is held at both ends by internal lead wires 7 implanted in the stem 5. The glass tube 4 has a stem 5 at one end.
It is supported by the other end of the rod-shaped body 6 fixed to the top of. The cap 8 is electrically connected to the filament 2.

ではほとんど発光効率の上昇は認められなかった。According to experiments, in the configuration shown in FIG.
For 0V100W, the infrared reflective and visible light transmitting film 3 is a film with an 8-layer laminated structure of Tio-8io2, and the glass cylinder 4 is an outer diameter of 51 rM to 6 thin and a length of 1 o III.
The rod-shaped body 6 has an outer diameter of 411 mm.
It was observed that the rate of increase in luminous efficiency due to the infrared reflective and visible light transmitting film was improved to 110% in light bulbs using 1 to 1 oMM. In contrast, almost no increase in luminous efficiency was observed in light bulbs with a conventional structure in which an infrared reflective and visible light transmitting film was provided over the entire outer surface of the bulb.
□″ニガラス筒４外径が５ｇより小さいと、フィラメン
トの蒸発で黒化による光束低下が生じる。□''If the outer diameter of the glass tube 4 is smaller than 5 g, the luminous flux will decrease due to blackening due to evaporation of the filament.

方が作業性が良い。If it is larger than 20 MM, it will be difficult to support the glass cylinder and the rate of increase in luminous efficiency will be small. Further, the length is preferably about 3 mm longer than the filament 2.0 It is better to change the outer diameter of the rod-shaped body 6 depending on the size of the glass cylinder 4 for better workability.
