Abstract
The utility model provides an internal-trigger high-voltage sodium lamp used for a daylighting situation of large area, comprising in series of a switch, an amperite and an electric arc tube. Internal triggering devices are positioned in parallel on the both ends of the electric arc tube, the electric arc tube, the internal triggering devices, a lamp cap and a button stem are assembled in a glass envelope, and the internal triggering devices are composed in series of a jump bulb and a bimetal protecting sheet. The utility model has the advantages of high light effect, long service life, conservation of energy, simple lighting circuit, etc. Because the triggering devices are assembled in the tube, the operation is reliable.
Description
One, technical field
The utility model relates to a kind of illumination component, relates in particular to the internal trigger high-pressure sodium lamp.
Two, background technology
The high-voltage gas discharging light bubble is widely used in the occasion that road, square etc. need large tracts of land daylighting.When high-pressure sodium lamp used, all needing trigger equipment could work, and the maximum of usefulness are the external trigger types now, and the internal trigger type is relatively poor owing to reliability, and the life-span is short than sodium vapor lamp, so seldom use.This sodium vapor lamp is when power connection, and electric current is by heater strip and bimetal leaf, makes the bimetal leaf back flexural deformation of being heated, and the contact disconnects.The moment that disconnects in the contact, the transient characterisitics of ballast produce a high-voltage pulse, are added in the two ends of discharge tube core, and lamp is lighted.After lamp was lighted, the discharge die temperature raise gradually, adds thrermostatic bimetal-plate, makes it be in case of bending always, only remained after lamp extinguishes intensity decreases, just reinstatement of bimetal leaf.This Starting mode reliability is relatively poor, and resistance is in the high temperature easily agingly, and the start-up time and the time of restarting are also long, and bimetal leaf is in case of bending for a long time, makes sodium vapor lamp easily before itself damaging as yet, makes sodium vapor lamp can't continue use because of starting drive loses efficacy.
Three, technology contents:
Technical problem: the utility model provides a kind of illumination of long service life internal trigger high-pressure sodium lamp.
Technical scheme: a kind of internal trigger high-pressure sodium lamp that uses in large tracts of land daylighting occasion; be composed in series by switch, ballast and electric arc tube; be parallel with the internal trigger device at the two ends of electric arc tube; electric arc tube and internal trigger device are located in the glass bulb; in glass bulb, also be provided with lamp holder and stem stem, it is characterized in that the internal trigger device is composed in series by jumping bubble and bimetallic screening glass.
Beneficial effect: the utility model is when connecting K switch, and electric current makes the work of jumping bubble through ballast B, jumping bubble S and screening glass P, and electric current is a → b → c → d → e → f through the path.When jumping bubble work, on B, produce back electromotive force, promptly between a, f, produce high back voltage, make that lamp is instantaneous to be lighted.The utility model is used and is jumped bubble replacement resistance, and constitutes the internal trigger device by bimetallic screening glass and the series connection of jumping bubble, and the life-span of jumping bubble and bimetal leaf all obtains prolongation like this.It is that sodium vapor lamp will be lighted several hours to tens hours owing to jump the every work of bubble once that the life-span of jumping bubble prolongs, and the life-span of jumping bubble can reach several ten thousand times, therefore, and considerably beyond the useful working life of sodium vapor lamp.Lamp is lighted back jumping bubble and is quit work, the bimetallic screening glass of internal trigger device is restored to the original state, thereby make the advantage that the utlity model has long service life, when lamp starts just often, jump the bubble protective device and start working, 2 of d, e begin to separate, make the utility model when electric arc tube both end voltage (modulating voltage) raises pressure, because d, e disconnect, avoid jumping the bubble misoperation, and lamp is extinguished; Characteristics of the present utility model are: need not electronic trigger can normal ignition use, and in addition, also has the light efficiency height, the life-span is long, energy-conservation and puts advantages such as lamp driver is simple.Because trigger equipment is placed in the pipe, thereby reliable operation.
