Metal vapor lamp having internal means promoting condensate film formation |
| abstract |
In a high intensity metal halide discharge lamp, means are provided associated with the interior surface of the envelope to promote the formation and spreading of a liquid film of condensate thereon. Such a film can lower the color temperature as a result of pressure broadening and self-reversal of the sodium line, and also by acting as a color correcting filter. The film-promoting means may be a coating which imparts an irregularity to the surface such that the reduction in exposed surface area by coverage with a uniform liquid film is energetically favored. Alternatively, a chemically different surface better wetted by the metal halide dose may be used. |
