Embodiment Construction
[0014] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.
[0015] like figure 1 As shown in the figure, the ceramic xenon discharge lamp filled with lanthanide halide of this embodiment includes a sealed casing and a ceramic arc tube arranged in the sealed casing. The ceramic arc tube is provided with a filling space and electrodes. The filling space is filled with fillers, and the fillers are xenon gas, metal halide, and nano-silicon, wherein, by mass fraction, the metal halide is 60% to 70% of the filler, and the metal halide includes: sodium halide 80 %~90%, lanthanide halide 2%~6%, indium halide 0~1%, thallium halide 1%~1.5%, scandium halide 0.5%~1.5%, thorium halide 1%~5%, the electrode Thorium-coated tungsten or tungsten-thorium alloy.
[0016] The added lanthanide halide reduces the temperature of the bulb...
