Problems solved by technology

The luminous efficiency of sodium-thallium-indium series pills is around 80lm / W, and rarely reaches 90lm / w
In addition, the sodium-thallium-indium series of luminescent pills, at the end of the life of the lamp, due to the continuous penetration of sodium atoms into the quartz tube, the relative color temperature of the lamp rises to varying degrees, resulting in a large change in the light color of the lamp, which affects the use effect

preparation example Construction

[0028] see figure 1 , a method for preparing a luminescent pill for a metal halide lamp in one embodiment, is characterized in that it includes the following steps:

[0029] Step S110 , the mixture formed by mixing sodium iodide, thallium iodide, indium iodide, scandium iodide and thulium iodide is vacuum treated at 100° C. to 150° C. for 30 minutes to 60 minutes.

[0030] The molar ratio of sodium iodide, thallium iodide, indium iodide, scandium iodide and thulium iodide is 0.3~1.4:1.0×10 -3 ~1.4×10 -2 : 2.0×10 -3 ~5.0×10 -3 : 0.02~0.40: 2.0×10 -3 ~1.2×10 -2 .

[0031] Preferably, the mixture is placed in a quartz container with a nozzle for vacuum treatment.

[0032] Step S120, heating the mixture until melting, and stirring for 30 minutes to 50 minutes.

[0033] In this step, scandium iodide, thulium iodide and sodium iodide form a complex with a lower melting point under high temperature conditions.

[0034] Step S130 , under a protective gas atmosphere, the molte...

Abstract

The invention discloses a luminous composition for a metal halide lamp, the luminous composition includes sodium iodide, thallium iodide, indium iodide, scandium iodide and thulium iodide, and the molar ratio of the sodium iodide, the thallium iodide, the indium iodide, the scandium iodide and the thulium iodide is 0.3-1.4:1.0 * 10<-3>-1.4 * 10<-2>:2.0 * 10<-3>-5.0 * 10<-3>:0.02-0.40:2.0 * 10<-3>-1.2 * 10<-2>. The luminous composition for the metal halide lamp is high in luminous efficiency and less in influence on the using effect. The invention also provides a luminous pill for the metal halide lamp and a preparation method thereof.

Description

technical field [0001] The invention relates to a luminescent composition for a metal halide lamp, a luminescent pill for a metal halide lamp and a preparation method for the luminescent pill for a metal halide lamp. Background technique [0002] Metal halide lamps (referred to as metal halide lamps), as a green light source, have attracted much attention from the market. Its luminescent sodium-thallium-indium series luminescent pills are commonly used luminescent pills. The luminous efficiency of sodium-thallium-indium series pills is about 80lm / W, and rarely reaches 90lm / w. In addition, the sodium-thallium-indium series of luminescent pills, at the end of the life of the lamp, due to the continuous penetration of sodium atoms into the quartz tube, the relative color temperature of the lamp rises to varying degrees, resulting in a large change in the light color of the lamp, which affects the use effect. Contents of the invention [0003] Based on this, it is necessary ...
