Problems solved by technology

[0002] Metal halide white lamps are HPI lamps represented by PhilipS and China. The components of the luminous pills are eutectics of sodium iodide, thallium iodide, and indium iodide. This type of lamp is characterized by high luminous efficiency and long life. The light color emitted is cool blue-white (color temperature 4700-5500K) and can be easily replaced by high-pressure mercury lamps. The disadvantage is that the color rendering is poor, the color rendering index is about 60, and the light color consistency is poor.

Abstract

The invention discloses a luminous pill of a metal halide white lamp, which contains sodium iodide, thallium iodide, indium iodide, iridium iodide and americium iodide. Compared with the prior art, the prepared metal halide white lamp is characterized by good color rendering, the color rendering index being larger than 80, and good photochromic consistency.

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 white lamp with a color temperature of 4700-5500K. Background technique [0002] Metal halide white lamps are HPI lamps represented by PhilipS and China. The components of the luminous pills are eutectics of sodium iodide, thallium iodide, and indium iodide. This type of lamp is characterized by high luminous efficiency and long life. The light color emitted is cool bluish white (color temperature 4700-5500K) and can be easily replaced with a high-pressure mercury lamp. The disadvantage is that the color rendering is poor, the color rendering index is about 60, and the light color consistency is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a luminous pill of metal halide white lamp with high color rendering index and good light color consistency. [0004] The...
