High pressure gas discharge lamp. |
摘要 |
<p>An electrodeless high pressure discharge lamp contains a halide or oxyhalide of W, Ta, Re, or rhenium oxide in such a quantity that a supersaturated metal vapour arises in the discharge, by which metal particles are formed. Owing to their high temperature these particles generate thermal emission. The lamp has a high colour temperature and a high colour rendering index.</p> |
