Abstract

The invention discloses a mercury-free ceramic metal halide lamp light-emitting pill and a preparation method thereof, as well as a mercury-free ceramic metal halide lamp. The mercury-free ceramic metal halide lamp light-emitting pill contains a first metal halide and a second metal halide in the weight ratio of (24-50) to (5-20), wherein the first metal halide comprises 50-80% by weight of thulium iodide, 5-10% by weight of praseodymium iodide and the balance of thallium iodide, and the second metal halide is zinc iodide. The preparation method comprises the following steps: preparing a fused solution of a mixture of the first metal halide and the second metal halide, spraying out the fused solution of the mixture, cooling and solidifying to form spheres, and performing impurity removal and screening treatment on the spheres formed by solidification. The mercury-free ceramic metal halide lamp disclosed by the invention adopts the synergistic effect of thulium iodide, indium iodide and thallium iodide, so that the mercury-free ceramic metal halide lamp containing mercury-free ceramic metal halide lamp light-emitting pills can increase pipe voltage in working process and reduce the energy consumption of a ballast, and has the performances of high light efficiency, 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 luminous 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, aff...
