Description
Technical field
the utility model belongs to technical field of electricity, particularly a kind of gaseous discharge lamp.
Background technology
high-pressure sodium vapour discharge lamp is a class of gaseous discharge lamp, and it is by the arc discharge in fluorescent tube, then produces very strong light in conjunction with the inert gas of filling in fluorescent tube or metal vapors.
High-pressure sodium lamp sends golden white light when using, and 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.Be widely used in road, highway, airport, harbour, dock, station, square, street intersection, industrial and mining enterprises, park, garden illumination and plant culture.High colour developing high-pressure sodium lamp is mainly used in gymnasium, show room, public place of entertainment, department store and hotels and other places illumination.
After bulb starts, electric arc is produced between electric arc tube two end electrodes, high temperature action due to electric arc makes the evaporation of being heated of the sodium amalgam in pipe become mercury vapour and sodium vapor, the electricity of cathode emission is in anode motion process, clash into discharging substance and have atom, make it obtain energy generation ionization to excite, be then returned to stable state by excitation state; Or become excitation state from state of ionization, return ground level Infinite Cyclic, unnecessary energy discharges with the form of light radiation, just creates light.
In order to the illumination performance factor of the photon flux and so on of the luminous intensity or every watt of power of improving high-pressure sodium vapour discharge lamp, use higher internal gas pressure.But, because higher internal gas pressure needs larger firing pulse to light this gaseous discharge lamp.Therefore, the illuminating equipment component as device for igniting, socket etc. and so on must be able to take this larger firing pulse.A kind of mode addressed this problem reduces the firing pulse of high-pressure sodium vapour discharge lamp.Therefore, the distance between electrode can be reduced and/or can use lights assistant piece, such as starts or lights tactile line, and wherein, tactile line is usually the method selected.
Traditional tactile line is being coated with metal wire on bulb, when starting the lamp, the electric field action of complexed metal coil, in lamp, the most advanced and sophisticated technical ability of the metal needle of air chamber synchronously carries out effective electron emission, thus generation light, and make the light of generation effectively enter the discharge space of bulb, thus reach the effect promoting that bulb starts.Metal wire on traditional high-pressure sodium vapour discharge lamp is " work " font.
Utility model content
the purpose of this utility model is to provide a kind of high-pressure sodium vapour discharge lamp, to solve prior art Problems existing.
For achieving the above object, the utility model is by the following technical solutions:
A kind of high-pressure sodium vapour discharge lamp, comprise outer tube and interior pipe, interior pipe is arranged within the outer tube, the outer wall of described interior pipe is coated with tactile line, described tactile line comprises two longitudinal wire coils and horizontal metal wire, one end of described metal straight line connects one of them wire coil, and its other end passes another wire coil and extends to the end of interior pipe.
The inert gas such as nitrogen, argon gas is filled with in described outer tube.
The beneficial effects of the utility model are:
The utility model extends on routine " work " font metal wire, is reduced the firing voltage of bulb by the distance shortened between tactile line, has structure simple, advantage with low cost.
