必要とし、また可視光反射率が金属反射膜よりも若干劣
る欠点がある。(Conventional technology) Conventionally, in tubes such as light bulbs, without using a reflector,
It has been proposed that a metal reflective film is formed on a part of the tube bulb, or that an infrared-transmissive visible light-reflective interference film is formed. (Japanese Patent Application No. 62-210238, etc.) (Problem to be Solved by the Invention) When a metal reflective film is provided on a high-temperature bulb such as a halogen light bulb, the high temperature causes severe deterioration and the film becomes unusable in a short period of time. In addition, products with an infrared-transmitting, visible-light-reflecting interference film are highly heat resistant and have considerable infrared transmittance.
Applying this to halogen light bulbs has the advantage of reducing the amount of infrared radiation, but on the other hand, this infrared-transmitting, visible-light-reflecting interference film cannot be formed directly on the infrared-reflecting film, requires a large number of calendars, and also reflects visible light. It has the disadvantage that the reflection rate is slightly lower than that of metal reflective films.

合物重合体膜がシリカ膜（７１）に変成する。To form such a light-reflecting film (7), first, an organic silicon compound polymer such as an ethyl silicate polymer is dissolved in an organic solvent such as ethanol, and the silicon content is 2 to 2.
A solution having a concentration of 50% by weight and a viscosity of 1 to 10 cps is prepared, and the titanium oxide particles having a particle size of 0.01 to 10.0 μm are dispersed therein. Then, the sealed halogen bulb is held vertically, immersed in the solution in which the titanium oxide particles are dispersed up to a predetermined line, and pulled up at a constant speed to dry. Then,
A film of an organic silicon compound polymer containing titanium oxide particles is formed on the glass surface. In this case, the moisture in the air during pulling reacts with the organosilicon compound polymer to further progress polymerization and hydrolysis, and the reaction product forms on the glass surface (11) and titanium oxide particles (72).
It adheres to the surface of the surface and fills these gaps. Then, by further heat treatment, the silicon compound polymer film described above is transformed into a silica film (71).
