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
The invention belongs to the Illuminant pill of metal halide lamp, belong to the Illuminant pill that colour temperature is the metal halide rare-earth lamp of 5800-6200K especially.
Background technology
Metal halide rare-earth lamp be represented as OSRAM, the Illuminant pill of such lamp is the complex compound eutectic of Main Ingredients and Appearance with iodate dysprosium (holmium, thulium), sodium iodide, thallium iodide (indium), cesium iodide.The characteristics of this class lamp are color rendering good (Ra＞80), and very near daylight, correlated colour temperature＞5500K, light are cold white, but that its shortcoming is a luminous efficiency is lower, and luminous efficiency is usually less than 80lm/w, and also be lower than 5000 hours useful life.
Summary of the invention
Technical problem to be solved by this invention provides the Illuminant pill of the metal halide rare-earth lamp of a kind of luminous efficiency height, long service life.
The technical scheme of technical solution problem of the present invention is: a kind of Illuminant pill of metal halide rare-earth lamp, contain sodium iodide, thallium iodide, indium iodide, and iodate dysprosium, cesium iodide also contain iodate iridium, iodate berkelium.
Described sodium iodide, thallium iodide, indium iodide, the mol ratio of iodate dysprosium, cesium iodide, iodate iridium, iodate berkelium is 1: 0.3-0.8: 0.04-0.08: 0.002-0.007: 0.001-0.005: 0.002-0.004: 0.001-0.003.
Preferred sodium iodide, thallium iodide, indium iodide, the mol ratio of iodate dysprosium, cesium iodide, iodate iridium, iodate berkelium is 1: 0.4: 0.06: 0.004: 0.003: 0.003: 0.002.
The colour temperature of described metal halide rare-earth lamp is 5800-6200K.
The present invention utilizes iodate iridium to improve the luminous efficiency of metal halide rare-earth lamp, when the molar concentration of iodate iridium is too low, does not have the effect that increases luminous efficiency, and when its molar concentration is too high, reduces the luminous efficiency of metal halide rare-earth lamp on the contrary.
The present invention utilizes the iodate berkelium to improve the useful life of metal halide rare-earth lamp.
The present invention compared with prior art, prepared metal halide rare-earth lamp, it is good to have luminous efficiency, luminous efficiency is more than the 100Lm/w, reaches 10000 hours characteristics useful life.
