Abstract
The utility model discloses an electric arc tube of gas discharge lamps, which comprises inner tube, an electrode is arranged on the inner tube, and the outer surface of the inner tube is provided with conductive bands. The conductive band is a closed conductive band, the outer surface of the inner tube is at least provided with two conductive bands, and spiral conductive bands are connected among the conductive bands. The conductive bands on the outer surface of the inner tube of the utility model can increase the homogeneity of electric field distribution in the tube, reduce glow starting voltage, decrease the dynamic range of the glow starting voltage and increase the consistency of the glow starting, and the glow starting voltage can cause the brightness of the utility model to be uniform.
Description
One, technical field
The utility model relates to a kind of electric arc tube, especially the gaseous discharge lamp electric arc tube.
Two, background technology
The starter dynamic range of existing electric arc tube is big, and therefore, the starter consistency is relatively poor, and the dynamic range of starter greatly also will cause brightness irregularities.
Three, technology contents
Technical problem the utility model provides a kind of gaseous discharge lamp electric arc tube that can improve starter consistency and brightness uniformity.
A kind of gaseous discharge lamp electric arc tube of technical scheme, pipe 1 is provided with electrode 2 in comprising on interior pipe 1, is provided with conductive strips 3 on the outer surface of interior pipe 1.
Conductive strips on beneficial effect (1) inner tube outer surface can improve the uniformity that the pipe internal electric field distributes, and reduce starting voltage, and the dynamic range of starting voltage is reduced, and have improved the consistency of starter, and low starting voltage makes brightness of the present utility model even again.(2) closed conductive strips, especially many closed conductive strips or many annular conductive strips, and utilize the bar shaped conductive strips with technical measures such as closed conductive strips link together, make the pipe internal electric field more become to being evenly distributed, thereby further improved defective of the present utility model, make the starter consistency better, brightness is more even.
Four, description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model embodiment front view.
Fig. 3 is another embodiment front view of the utility model.
Five, specific embodiments
Embodiment 1 the utility model is a kind of gaseous discharge lamp electric arc tube, pipe 1 in comprising, on interior pipe 1, be provided with electrode 2, on the outer surface of interior pipe 1, be provided with conductive strips 3, in the present embodiment, at least be provided with 2 conductive strips on the outer surface of interior pipe 1, conductive strips are annular conductive strips, are connected with bar shaped conductive strips 31 between conductive strips 3.
