Embodiment Construction
[0013] Embodiment of the manufacturing process of the rare earth metal halide lamp of the present invention:
[0014] Embodiment technological process sees figure 1 , The lamp making process includes arc tube production, inner tube assembly, shell clamping, shell exhaust, head soldering, finished product mature retest, printing and packaging, and inspection and storage. The production of the arc tube includes connecting the quartz tube and the quartz exhaust pipe; clamping the quartz tube connected to the quartz exhaust tube, the electrode, and the molybdenum component; exhausting after the clamping, the exhaust contains rare earth metal halides, mercury and inert gas filling process; after exhausting, conduct arc tube aging, restart voltage test-flame coating-arc tube retest-inspection-arc tube storage. The arc tube and the racking parts are assembled with the inner tube, and the racked arc tube and the quartz shell are clamped and sealed together after the inner tube is ass...

The invention discloses a high intensity discharge lamp manufacturing process and a high intensity discharge lamp, particularly to a rare earth metal halide lamp manufacturing process and a rare earthmetal halide lamp. In the rare earth metal halide lamp manufacturing process, metal halides filled in an arc tube of the rare earth metal halide lamp by weight percentage are 19-22% of DyI3, 22-25% of TmI3, 20-24 of HoI3, 8-12% of CsI, and 22-25% of TlI. Compared with the lamp in the prior art, the color rendering performance and the service life of the high color temperature rare earth metal halide lamp manufactured through the rare ear metal halide lamp manufacturing process are greatly improved. Through tests, the color rendering index Ra of a 150W double-end rare earth metal halide lamp with the color temperature being 6000K can reach 90, and the service life thereof can reach 10000h.
Description
technical field [0001] The invention relates to a high-intensity gas discharge lamp manufacturing process and the high-intensity gas discharge lamp, in particular to a rare-earth metal halide lamp manufacturing process and the rare-earth metal halide lamp that can be used for large-area indoor and outdoor commercial lighting. Background technique [0002] As a high-intensity gas discharge lamp, the rare earth metal halide lamp has the advantages of high luminous efficiency, low light decay, long life, good color rendering, and ultraviolet cutoff. It is a green and energy-saving lighting source; especially for general lighting 150W double-ended Rare earth metal halide lamps have been widely used in indoor and outdoor commercial lighting because of their small size, compact structure, and easy installation and replacement. [0003] The manufacturing process of rare earth metal halide lamps in the prior art includes arc tube production, inner tube assembly, shell clamping, shel...
