Embodiment 1
[0016] A metal halide lamp pill, containing scandium iodide, sodium iodide, thorium iodide, thallium iodide, indium iodide, lithium iodide, the weight ratio of each component is: scandium iodide 90 parts, iodide 20 parts of sodium, 0.1 part of thorium iodide, 0.15 part of thallium iodide, 0.04 part of indium iodide, 0.15 part of lithium iodide, and 0.1 part of dysprosium iodide. A 400W metal halide lamp was made by using the metal halide lamp pellets, with a luminous efficiency of 125Lm / w, a color rendering index of 85, a color temperature of 4600K, and a service life of 12500 hours.
Embodiment 2
[0018] A metal halide lamp pill, containing scandium iodide, sodium iodide, thorium iodide, thallium iodide, indium iodide, lithium iodide, the weight ratio of each component is: scandium iodide 80 parts, iodide 12 parts of sodium, 0.04 parts of thorium iodide, 0.08 parts of thallium iodide, 0.01 part of indium iodide, 0.07 parts of lithium iodide, and 0.07 parts of dysprosium iodide. A 400W metal halide lamp was made by using the metal halide lamp pellets, with a luminous efficiency of 123Lm / w, a color rendering index of 82, a color temperature of 4590K, and a service life of 12500 hours.
Embodiment 3
[0020] A metal halide lamp pill, containing scandium iodide, sodium iodide, thorium iodide, thallium iodide, indium iodide, lithium iodide, the weight ratio of each component is: scandium iodide 70 parts, iodide 10 parts of sodium, 0.03 parts of thorium iodide, 0.05 parts of thallium iodide, 0.01 part of indium iodide, 0.05 parts of lithium iodide, and 0.05 parts of dysprosium iodide. A 400W metal halide lamp was made by using the metal halide lamp pellets, with a luminous efficiency of 120Lm / w, a color rendering index of 80, a color temperature of 4500K, and a service life of 12000 hours.

technical field [0001] The invention belongs to the field of light sources, and in particular relates to a metal halide lamp pill. Background technique [0002] Metal halide lamps are the third-generation light source made by adding various metal halides on the basis of high-pressure mercury lamps. It seals rare earth gases, metal halides and mercury inside the luminous tube. Rare earth gases are mainly used to make metal halide lamps easy to start and can emit strong light immediately after starting, metal halides are used to produce appropriate light output in a stable ignition state, and mercury is used to generate The relatively high inter-electrodevoltage required for metal halide lamp operation. Metal halide lamps have the characteristics of high luminous efficiency, good color rendering performance, and long life. They are energy-saving light sources close to daylight color and are widely used in indoor lighting. [0003] Metal halide lamp pellets refer to metal ha...
