2. Description of the Related Art In a bulb such as a halogen bulb, the emitted infrared rays are reduced by an infrared reflection film to achieve high efficiency and high functionality of the bulb and lighting equipment. For example, there are the following three types of infrared reflection films of this type.

The method (1) is generally used for an infrared reflection film on the outer surface of a halogen bulb, various filters of a dichroic mirror, and the like. Optically, it has a high transmittance in the visible light region and reflects the infrared region with high efficiency, but its reflection region is narrow. In addition, heat resistance is high, but a large number of film layers are required, which increases costs and increases the number of manufacturing steps.

In the case of (2), the infrared reflection range is from about 1 μm, and the intensity of infrared radiation from a bulb or the like is 0.8 to 1 μm.
Do not cut too much around m. For this reason, the infrared cut ratio is low, and the heat resistance is lower than that of the above (1). Therefore, it is used for an NH outer tube, a front glass of a shield beam lamp, and the like.

In the case of (3), both the visible transmittance and the infrared reflectance are relatively good, and a sufficient effect can be obtained with around three layers. However, it has low heat resistance of about 200 to 300 ° C. or less, and is used only for general window glass, automobile window glass, and the like.

It has been proposed to use O, AlN, Si3NL or the like, or use a metal compound such as a nitride of TiN instead of Ag or the like.

Among such infrared reflecting films, those of (1) and (3) are widely used in practical use. In these reflective films, since a dielectric film such as TiO2 is used, a shift in optical characteristics occurs depending on the incident angle of light. Therefore, there is a problem that the film characteristics are relatively deteriorated particularly when used for a tube or the like. In addition, when the area of the substrate on which the film is formed is large or a curved surface, ordinary deposition, a coating method such as dip,
It may be difficult to form a uniform film.
