Description
Technical field
The invention belongs to photoelectric source technical field, and in particular to a kind of single-ended ceramic metal holide lamp arc tube.
Background technology
Metal current halide lamp arc tube makees the cavity of electric arc tube using quartz, and the defect of electric arc tube cavity made by its quartz
It is that cavity loads low, the too high rising for causing surface temperature of quartz ampoule area load, its quartzy deformation temperature 1120 of itself
DEG C, 1683 DEG C of softening temperature, below 1100 DEG C of temperature, the load design that can draw quartz chamber body from data is no more than
1100 DEG C, but its optimal gasification temperature of different halogenide is filled in cavity at 1400 DEG C, 2080 DEG C etc., due in cavity
Temperature can not meet gasification temperature point required by halogenide, cause the low general light efficiency of luminous flux in 85lm/W, color rendering index
Less than 80, its life-span was at 9000 hours.
Existing ceramic metal halide lamp arc tube is all the product of double-ended structure type, such as patent at present
CN101419894A discloses a kind of ceramic metal halide lamp arc tube, and mid portion draws for capillary tube for discharging chamber two ends
Go out, the electric arc tube is with high-purity a-Al2O3Polycrystalline translucent aluminium oxide (PCA) pottery is made up of material calcination, and electrode assemblie passes through
Tail pipe inserts ceramic discharge intracavity, and by glass solder by electrode assemblie and tail pipe clearance seal, its designing points is described mistake
The outer diameter face for crossing area is vertical with supervisor, tail pipe, and in "- -" type, the ceramic discharge chamber of transition region aperture surface is in cone, ceramic
Electric discharge intracavity filler metal halogenide, hydrargyrum, buffer gas.
And for example patent CN10439289A discloses a kind of single-ended two-tube ceramic gold-halogen lamp ray structure, including electric arc tube and
The electrode for arranging in which, electric arc tube is single-ended integral double-pipe cavity configuration, has a disadvantage in that two dependent cavitys, four
Electrode is two positive poles, two negative poles, and the electric discharge of two poles after powered up is produced by nearest two, when the both positive and negative polarity of electrode is pacified
When filling unreliable, cause each electrode of two cavitys to work, and this patent used the sealing-in mode of no comb,
This sealing-in operation not can achieve, or and production cost higher to manufacturing technique requirent is high；Meanwhile, as described in the patent, when
After one receptor extinguishes, another cavity is quickly lighted, and when lamp is after lighting, expansion under the gas high temperature in cavity produces high gas
The condition of pressure, electric arc is it is difficult to start under the conditions of anticyclonic, can just light after need to cooling down a few minutes, but from experiment card
Bright this under the conditions of the cavity lighted of original easier start up, and this is physical phenomenon rather than the work under PC control, therefore,
Its technique effect is not as the alternation as described in the patent two cavity, so can not reach life-span length starting soon
