<p>LD 8323 METAL VAPOR LAMP HAVING INTERNAL COATING FOR EXTENDING CONDENSATE FILM The coating on the inside of a metal halide lamp for promoting the formation of a liquid condensate film consists of particles of a refractory oxide in generally block-like or spherical or fiber-like shapes. Blocklike or spherical particles should be laid down as monolayers with the distances between particles being of the order of the particle dimensions. Fiber like particles may be also laid down as a monolayer or, alternatively, in a coating several diameters thick to form "fiber piles" having a free volume for holding liquid which is much greater than the volume of the fibers.</p> |
