[0022] Correspondingly, the embodiment of the present invention also provides a method for preparing the mercury-free ceramic metal halide lamp luminous pill in the above embodiment, the process of the method is as follows figure 1 shown. The method comprises the steps of:
[0023] S01. Prepare the molten mixture of the first type of metal halide and the second type of metal halide: mix the first type of metal halide and the second type of metal halide in the embodiment of the above-mentioned mercury-free ceramic metal halide lamp light-emitting pills Afterwards, it is heated to melting in an oxygen-free atmosphere to obtain a molten liquid;
[0024] S02. Spray the molten mixture to cool and solidify into balls: spray the molten liquid prepared in step S01 into an atmosphere protected by a high-purity inert gas, and make liquid beads naturally form after spraying under the protection of the high-purity inert gas Cool in the atmosphere and solidify into balls;
[0025] S03. ...
Embodiment 1
[0054] A mercury-free ceramic metal halide lamp with a power of 70W. The structure of the mercury-free ceramic metal halide lamp is as described above and attached figure 2 , 3 As shown, wherein, the first type of metal halide and the second type of metal halide contained in the luminescent pill 3; wherein, the first type of metal halide contains 55wt% thulium iodide, 1wt% indium iodide, and 44wt% iodine Thallium; the second class of metal halides contains zinc iodide.
