Abstract:
     The invention relates to a light scattering coating with excellent effect of light scattering, a method for forming said coating and halogen lamps having said coating. Said coating contains air bubbles, which are covered in a coating layer made of oxides of metal on a fundamental surface. The method for forming is as follows: a composite of an organic compound of metal and an organic solvent with high boiling point is coated on the base surface. And then it is baked to make the organic compound of metal dissolve and form a coating of metal oxides. The air bubbles produced during evaporating of the solvent are contained in the coating. The porous light scattering coating of the halogen lamp is formed on another coating, which is transparent for visible light but reflects infrared light. The stress, caused at high temperature by the difference in the heat expansion coefficients of the lamp bulb material and the light scattering layer, can be absorbed by the porous structure, and ......
