Abstract

The invention discloses a non-mercury ceramic metal halide lamp luminous pill, a preparation method thereof and a non-mercury ceramic metal halide lamp. The non-mercury ceramic metal halide lamp luminous pill contains first metal halides and second metal halides according to the weight ratio of (24-50): (5-20); the first metal halides are composed of 55-83wt% of thulium iodide, 1-4wt% of indium iodide and the balance of thallium iodide, and the second metal halides contain zinc iodide. The preparation method of the non-mercury ceramic metal halide lamp luminous pill comprises the following steps: preparing the mixture melted liquid of the first halides and the second halides, spraying and cooling the mixture melted liquid to form pills through solidification, and carrying out impurity removal and sieving treatment on the pills through solidification. The non-mercury ceramic metal halide lamp adopts the synergistic effect of thulium iodide, indium iodide and thallium iodide, so that the pipe pressure can be improved during the working process of the non-mercury ceramic metal halide lamp containing the non-mercury ceramic metal halide lamp luminous pills, the energy consumption of a ballast is reduced, and the non-mercury ceramic metal halide lamp has the performance of high lighting effect, good color rendering index and color temperature, long service life and the like.

Description

technical field [0001] The invention belongs to the technical field of lighting and optoelectronics, and in particular relates to a mercury-free ceramic metal halide lamp luminescent pill, a preparation method thereof and a mercury-free ceramic metal halide lamp. Background technique [0002] Most of the ceramic metal halide lamps currently on the market contain rare gases, metal halides and mercury. When the metal halide lamp is working normally, the metal halide is the main material for luminescence, and the proportion of mercury and rare gases in the visible light spectrum emitted by the metal halide lamp is relatively low. As a buffer gas, mercury can maintain the metal halide lamp to work at a higher tube pressure, which will improve the life and light efficiency of the metal halide lamp. However, mercury is a harmful substance with a high vapor pressure at room temperature. After being inhaled into the human body, it will accumulate in the human body for a long time, ...
