Abstract

The invention discloses a luminous pill of a metal halide rare-earth lamp, which contains sodium iodide, thallium iodide, indium iodide, dysprosium iodide, caesium iodide, iridium iodide and berkelium iodide. Compared with the prior art, the prepared metal halide rare-earth lamp is characterized by good luminous efficiency being more than 100Lm/w, and long service life lasting for 10000 hours.

Description

technical field [0001] The invention belongs to a luminescent pill for a metal halide lamp, in particular to a luminescent pill for a metal halide rare earth lamp with a color temperature of 5800-6200K. Background technique [0002] Representatives of metal halide rare earth lamps are OSRAM and China. The luminous pills of this type of lamps are composed of dysprosium iodide (holmium, thulium), sodium iodide, thallium iodide (indium), and cesium iodide. melt. This type of lamp is characterized by good color rendering (Ra>80), very close to sunlight, correlated color temperature>5500K, and cool white light, but its disadvantage is that the luminous efficiency is low, usually lower than 80lm / w, and the service life Also less than 5000 hours. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a luminescent pill for metal halide rare earth lamps with high luminous efficiency and long service life. [0004] The ...
