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
The invention belongs to a kind of Illuminant pill of metal halide lamp, belong to the Illuminant pill that colour temperature is the metal halide white lamp of 4700-5500K especially.
Background technology
Metal halide white lamp is that PhilipS, China are the HPI lamp of representative, the composition of its Illuminant pill is the eutectic of sodium iodide, thallium iodide, indium iodide, the characteristics of such lamp are that luminous efficiency height, life-span are long, send photochromic for refrigerant blue white (colour temperature 4700-5500K) partially but and the simple substitute high-pressure mercury lamp, its shortcoming is that color rendering is relatively poor, and color rendering index is about 60, photochromic consistency is poor.
Summary of the invention
Technical problem to be solved by this invention provides the Illuminant pill of the metal halide white lamp of a kind of color rendering index height, photochromic high conformity.
The technical scheme of technical solution problem of the present invention is: the Illuminant pill of metal halide white lamp, contain sodium iodide, thallium iodide, indium iodide, and also contain iodate iridium, iodate americium.
The mol ratio of described sodium iodide, thallium iodide, indium iodide, iodate iridium is 1: 0.2-0.6: 0.045-0.06: 0.003-0.006: 0.001-0.003.
The mol ratio of preferred sodium iodide, thallium iodide, indium iodide, iodate iridium is 1: 0.4: 0.05: 0.004: 0.002.
The colour temperature of described metal halide white lamp is 4700-5500K.
The present invention utilizes iodate iridium to improve the color rendering index of metal halide white lamp, when the molar concentration of iodate iridium is too low, does not have the effect that increases color rendering index, and when its molar concentration is too high, reduces the color rendering index of metal halide white lamp on the contrary.
The present invention improves the photochromic consistency of metal halide white lamp with the iodate americium
The present invention compared with prior art, prepared metal halide white lamp, it is good to have color rendering, color rendering index greater than 80, the characteristics of photochromic high conformity.
