Abstract
The utility model discloses a high voltage sodium lamp. The high voltage sodium lamp comprises a lamp cap and a glass bulb, the glass bulb is internally provided with a core column connected with the lamp cap, an upper support and a lower support are arranged on the core column, an electric arc tube is arranged between the upper support and the lower support, both ends of the electric arc tube are provided with niobium tubes, the niobium tubes at both ends of the electric arc tube movably sleeve end parts of the upper support and the lower support, connecting flexible leads are arranged between the niobium tubes and the upper support and between the niobium tubes and the lower support, one ends of the connecting flexible leads are welded to outer walls of the niobium tubes, the other ends are welded to a corresponding lamp holder, and the connecting flexible leads are braided flexible leads. The high voltage sodium lamp is simple in structure, during work, the electric arc tube is not subjected to acting force of the lamp holder when length changes due to heat expansion and cold contraction, and the high voltage sodium lamp is stable and reliable in work, and has a long service life.
Description
Technical field
The utility model relates to a kind of lighting, especially a kind of high-pressure sodium lamp.
Background technology
High-pressure sodium lamp has that luminous efficiency is high, little power consumption, life-span are long, mist transmitting performance lures the advantages such as worm by force and not, is widely used in road, highway, airport, harbour, dock, station, square, industrial and mining enterprises, park, garden illumination and plant culture.The electric arc tube of high-pressure sodium lamp can generate heat in the time of work, the impact of the effect of being expanded 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 variation 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.In prior art, destroy for fear of the electric arc tube effect of being expanded with heat and contract with cold, conventionally adopt the niobium pipe at electric arc tube two ends is connected and fixed by C shape frame and lamp bracket, utilize the distortion of C shape frame to absorb the length variable of electric arc tube, reach the object of avoiding the electric arc tube effect of being expanded with heat and contract with cold to destroy.But, adopt the high-pressure sodium lamp of this structure, because the distortion of C shape frame can cause the weld of C shape frame and lamp bracket, niobium pipe stressed, in use procedure, easily there is weld part cracking, sealing-off phenomenon, affect the normal use of high-pressure sodium lamp.
Utility model content
The technical problem that utility model will solve is: a kind of high-pressure sodium lamp is provided, and this high-pressure sodium lamp is simple in structure, can not be subject to the active force of lamp bracket when electric arc tube, because expanding with heat and contract with cold, length variations occurs when work, and this high-pressure sodium lamp working stability is reliable, long service life.
The technical scheme that technical solution problem is taked: a kind of high-pressure sodium lamp, comprise lamp holder, glass bulb, in glass bulb, be provided with the stem stem being connected with lamp holder, on stem stem, be provided with upper bracket and lower carriage, between upper bracket and lower carriage, be provided with electric arc tube, electric arc tube two ends are provided with niobium pipe, the niobium pipe movable set at electric arc tube two ends is in upper bracket and lower carriage end, between niobium pipe and upper bracket, be respectively equipped with connection flexible conductor between niobium pipe and lower carriage, connect flexible conductor one end and be welded on niobium pipe outer wall, the other end is welded on corresponding lamp bracket.
As further improvement of the utility model: described connection flexible conductor is braiding flexible conductor.
Beneficial effect: high-pressure sodium lamp of the present utility model, owing to having adopted described high-pressure sodium lamp to comprise lamp holder, glass bulb, in glass bulb, be provided with the stem stem being connected with lamp holder, on stem stem, be provided with upper bracket and lower carriage, between upper bracket and lower carriage, be provided with electric arc tube, electric arc tube two ends are provided with niobium pipe, the niobium pipe movable set at electric arc tube two ends is in upper bracket and lower carriage end, between niobium pipe and upper bracket, between niobium pipe and lower carriage, be respectively equipped with connection flexible conductor, connecting flexible conductor one end is welded on niobium pipe outer wall, the other end is welded on the technical scheme of corresponding lamp bracket, by niobium pipe and upper, lower carriage pivot bush unit, make the niobium pipe can be upper, between lower carriage, there is certain free travel, the length variations having produced while having avoided electric arc tube work causes electric arc tube stress destruction, therefore, high-pressure sodium lamp of the present utility model has simple in structure, this high-pressure sodium lamp working stability is reliable, the advantage of long service life, be the technical characterictic of braiding flexible conductor owing to having adopted described connection flexible conductor, in guaranteeing electric conductivity, wire is more soft, durable.
Accompanying drawing explanation
Below in conjunction with embodiment, high-pressure sodium lamp of the present utility model is described in further detail.
Fig. 1 is the structural representation of high-pressure sodium lamp of the present utility model.
Embodiment
As shown in Figure 1, high-pressure sodium lamp of the present utility model, comprise lamp holder 8, glass bulb 1, in glass bulb, be provided with the stem stem 7 being connected with lamp holder, on stem stem, be provided with upper bracket 5 and lower carriage 6, between upper bracket and lower carriage, be provided with electric arc tube 4, electric arc tube two ends are provided with niobium pipe 3, the niobium pipe movable set at electric arc tube two ends is in upper bracket and lower carriage end, between niobium pipe and upper bracket, between niobium pipe and lower carriage, be respectively equipped with and be connected flexible conductor 2, connect flexible conductor one end and be welded on niobium pipe outer wall, the other end is welded on corresponding lamp bracket, and described connection flexible conductor is braiding flexible conductor.
Claims (2)
1. a high-pressure sodium lamp, comprise lamp holder, glass bulb, in glass bulb, be provided with the stem stem being connected with lamp holder, on stem stem, be provided with upper bracket and lower carriage, between upper bracket and lower carriage, be provided with electric arc tube, electric arc tube two ends are provided with niobium pipe, the niobium pipe movable set at electric arc tube two ends is in upper bracket and lower carriage end, it is characterized in that: between niobium pipe and upper bracket, be respectively equipped with connection flexible conductor between niobium pipe and lower carriage, connect flexible conductor one end and be welded on niobium pipe outer wall, the other end is welded on corresponding lamp bracket.
