UV-reflecting layer, lamp with such a layer, and method of providing such a layer on a lamp glass |
| 摘要 |
In an UV-reflecting layer for discharge lamps, the layer comprises at least 0.1% by weight of Al<SUB>2</SUB>O<SUB>3 </SUB>and at least 0.1% by weight of a material having a higher refractive index than Al<SUB>2</SUB>O<SUB>3</SUB>, so that as large a proportion of UV light as possible can be reflected and as large a portion of visible light as possible can be emitted by the lamp.
