LAMPEN VOOR HOGE VERMOGENS. |
| 摘要 |
A lamp, particularly for high powers, whose envelope consists of lime glass and in which in a 30 mu thick surface layer Na+ - and/or Li+ ions are replaced by larger ions. This results in a compressive stress in the layer which is at least 7 kg/mm2. The envelope is as strong and resistant to temperature changes as hard glass. |
