Abstract
The utility model discloses a metal halide lamp electric arc tube comprising a tube housing and two electrode outlet tubes, which are integratedly arranged. The electrode outlet tubes are disposed on two ends of the tube housing. The utility model is characterized in that a cylinder-shaped tube segment and cone-shaped tube segments are integratedly arranged; the cone-shaped tube segments are symmetrically disposed on two ends of the cylinder-shaped tube segment; a maximum internal diameter of a large caliber end of each of the cone-shaped tube segments is equal to an internal diameter of the cylinder-shaped tube segment, and a minimum internal diameter of a small caliber end of each of the cone-shaped tube segments is equal to an internal diameter of each of the electrode outlet tubes; the large caliber ends of the cone-shaped tube segments are integratedly connected with the two ends of the cylinder-shaped tube segment; the ends of the electrode outlet tubes are integratedly connected with the small caliber ends of the cone-shaped tube segments; an arc discharging chamber can be enclosed by the cylinder-shaped tube segment and the cone-shaped tube segments; when the metal halide lamp is in use, sound waves generated by the alternating current arc can return to the axial central line of the arc discharging chamber uniformly after the reflection of the inner wall of the tube housing. The utility model is advantageous in that by using the metal halide lamp with the metal halide lamp electric arc tube adopting the above mentioned structure, the sound resonance problem can be effectively prevented without the frequency modulation, when the high frequency electronic ballast is used.
Description
Technical field
The utility model relates to a kind of Metal halogen lamp, especially relates to a kind of halogen electric arc tube.
Background technology
Metal halogen lamp is to produce the luminous discharge lamp of arc discharge in the halide mixed vapour of mercury and rare metal, is applied to various important events because it has the advantages such as luminous efficiency is high, color developing good, the life-span is long.Metal halogen lamp is when work, typically use that AC power drives, the electric arc of alternation can produce sound wave, the shell of existing halogen electric arc tube all is elliposoidal or sphere basically, sound wave is followed principle of reflection, sound wave after the reflection can be got back to focus or the centre of sphere of ellipsoid and assemble, when the halogen electric arc tube adapted high-frequency electronic ballast of this kind structure is worked, high-frequency reflective sound wave can blow the electric arc that is positioned on the shell center line, make the Metal halogen lamp job insecurity, because there is serious acoustic resonance problem in Metal halogen lamp during the adapted high-frequency electronic ballast, therefore Metal halogen lamp great majority in the market all are the adapted low-frequency electronic ballasts, but the volume of low-frequency electronic ballast is large, the high popularization that is unfavorable for Metal halogen lamp of cost, although the Metal halogen lamp by warbled method adapted high-frequency electronic ballast is also arranged, but often modulation circuit is too complicated, needs frequency is limited in certain number range, and the effect that implements difficulty and inhibition acoustic resonance is also not obvious.
Summary of the invention
Technical problem to be solved in the utility model need not the halogen electric arc tube that the acoustic resonance problem just can be effectively avoided in frequency modulation(FM) when providing a kind of adapted high-frequency electronic ballast.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of halogen electric arc tube, comprise shell and two electrode extraction tubes of being wholely set, described electrode extraction tube is positioned at the two ends of described shell, described shell comprises cylindrical pipeline section and the taper pipeline section that is wholely set, described taper pipeline section is symmetricly set on the two ends of described cylindrical pipeline section, the maximum inner diameter of the heavy caliber end of described taper pipeline section equates with the internal diameter of described cylindrical pipeline section, the minimum diameter of the small-caliber end of described taper pipeline section equates with the internal diameter of described electrode extraction tube, the heavy caliber end of described taper pipeline section is connected with the end one of described cylindrical pipeline section, the end of described electrode extraction tube is connected with the small-caliber end one of described taper pipeline section, described cylindrical pipeline section and described taper pipeline section together surround the arc discharge chamber, during Metal halogen lamp work, get back to equably on the longitudinal center line in arc discharge chamber after the inwall reflection of the sound wave that alternation electric arc produces by shell.
The wall thickness of described cylindrical pipeline section equates with the wall thickness of described taper pipeline section.
The cone angle of described taper pipeline section is 15 ° ~ 65 °.
The cone angle of described taper pipeline section is 45 °.
The axial length in described arc discharge chamber is 1.7 ~ 4 times of internal diameter of described cylindrical pipeline section.
Described cylindrical pipeline section, described taper pipeline section and described electrode extraction tube all adopt translucent alumina ceramics to make, and are applicable to ceramic gold-halogen lamp.
Described cylindrical pipeline section, described taper pipeline section and described electrode extraction tube all adopt quartz to make, and are applicable to quartz metal halide lamp.
Compared with prior art, the Metal halogen lamp that the utility model has the advantage of the halogen electric arc tube that adopts this kind structure need not frequency modulation(FM) and just can effectively avoid the acoustic resonance problem when the adapted high-frequency electronic ballast, during Metal halogen lamp work, get back to equably on the longitudinal center line in arc discharge chamber after the inwall reflection of the sound wave that alternation electric arc produces by shell, overlap with the electric arc on the center line, can not produce local gathering, guarantee the stable of electric arc, thereby guarantee the steady operation of Metal halogen lamp; The experiment proved that, no matter electric arc tube of the present utility model is adapted low-frequency electronic ballast or high-frequency electronic ballast, can both be normally stable work, behind electric arc tube adapted high-frequency electronic ballast of the present utility model so that the cost of whole lamp greatly reduce, be conducive to the popularization of Metal halogen lamp, can allow Metal halogen lamp as electricity-saving lamp, enter huge numbers of families.
