Description
Technical field
The utility model relates to field of illumination lamp technology, is specifically related to novel high-pressure sodium vapor lamp.
Background technology
High-pressure sodium lamp (HPS): need, with ceramic arc light tube, to make it can bear the erosion of the mordant sodium vapor more than 1000 DEG C.Earthenware is arranged in glass or quartz bulb, makes it and air insulated.In all high-intensity gas discharge lamps, the light efficiency of high-pressure sodium lamp is the highest, and has the very long life-span (24001 hours), and therefore it is the perfect light source of center, city, parking lot, industrial building illumination.In these occasions, medium color rendering just can be satisfied the demand.Color rendering enhancement mode and white light type high-pressure sodium lamp also can be used, but this is to reduce light efficiency for cost.At present, the standard type NG1000 type high-pressure sodium lamp of domestic use, has lamp holder and lamp housing, inside is provided with electric arc tube, and electric arc tube two ends are provided with two electrode combinations, and carry out vacuum-tightness sealing-in, the Na Hg of certain proportion weight is put in electric arc tube, be filled with the inert gas of certain pressure, the modulating voltage of NG1000 type high-pressure sodium lamp is 110 ± 20V, and operating current is about 10.3A, circuit load electric current is large, lamp housing is cylinder, and space is little, and light is logical and light efficiency is lower.The electric arc tube of high-pressure sodium lamp operationally can generate heat, by the impact of the effect of expanding with heat and contract with cold, the length of electric arc tube can change, because electric arc tube two ends are fixed in glass bulb by support, therefore, the change of electric arc tube length can cause electric arc tube to be subject to tractive or the extruding force of support, easily causes electric arc tube to damage.Destroy in order to avoid the electric arc tube effect of being expanded with heat and contract with cold in prior art, the niobium pipe at electric arc tube two ends is connected and fixed by C shape frame and lamp bracket by usual employing, utilize the distortion of C shape frame to absorb the length variable of electric arc tube, reach and avoid electric arc tube to be subject to expand with heat and contract with cold the object of action breaks down.But, adopt the high-pressure sodium lamp of this structure, the distortion due to C shape frame can cause C shape frame and lamp bracket, niobium pipe weld stressed, easily there is weld part cracking, sealing-off phenomenon in use procedure, the normal use of impact to voltage sodium vapor lamp.
Summary of the invention
The purpose of this utility model mainly in order to solve the problems of the technologies described above, and provides novel high-pressure sodium vapor lamp.
The utility model comprises lamp socket, glass lamp shade, electric arc tube, electrode combination, fixed support, niobium pipe be connected flexible conductor, lamp housing inside is provided with electric arc tube, inert gas is filled with in described electric arc tube, described electric arc tube two ends are provided with electrode combination, and be electrically connected with lamp socket by electrode combination, described glass lamp shade inside is provided with fixed support, niobium pipe is provided with at electric arc tube two ends, the niobium pipe movable set at electric arc tube two ends is on fixed support, connection flexible conductor is respectively equipped with between niobium pipe and fixed support, connecting flexible conductor one end is welded on niobium pipe outer wall, the other end is welded on fixed support.
Described connection flexible conductor is braiding flexible conductor.
Described glass lamp shade is air-tightness olive shape cloche.
Described electric arc tube material therefor is semi-transparent polycrystal aluminium oxide porcelain tube.
The utility model advantage is: have structure simple, this high-pressure sodium lamp working stability is reliable, the advantage of long service life; Owing to have employed the technical characteristic that described connection flexible conductor is braiding flexible conductor, while guarantee electric conductivity, wire is more soft, durable, has good practical value.
