Abstract

A trigger bulb in high-tension sodium lamp belongs to lighting lamp trigger technical field, wherein a glass post unit is leaded out a sealing wire in same expansion factor, while the inner end is welded with wires and dual metal sheets inclined inwards, to be sealed and arranged in a bulb frame filled with inert gas. The utility model is characterized in that inner two ends of the two near dual metal sheets are respectively welded with contactors which contain silver. The utility model can quickly switch the two contactors of the dual metal sheets to completely utilize the property of the internal trigger bulb.

Description

Bubble is jumped in the high-pressure sodium lamp internal trigger

Technical field

The trigger technology field that belongs to illuminating lamp exactly is that the bubble technology is jumped in a kind of internal trigger that relates to high-pressure sodium lamp.

Background technology

Adopt the high-pressure sodium lamp ubiquity also of the outer Starting mode of electronic trigger, big because of price height, volume, complicated, poor performance are installed, people more and more tend to the high-pressure sodium lamp of internal trigger mode.

The startup method is simple in traditional bimetal leaf thermal switch, form by bimetal leaf, the filament resistance that adds thrermostatic bimetal-plate or soft lead-in wire, contact, electric current flow through filament resistance or bimetal leaf when working, lamp are arranged, can produce the certain power loss, simply cause certain extra economic loss to the user though install.

Common internal trigger jumping bubble start-up course electric current is big, generate heat because of contact resistance between bimetal leaf and contact point or the bimetal leaf, the hot melt state appears, easily adhesion, influence sheet metal moment breaking speed, thereby having influenced the width and the peak value of trigger impulse, its startability often can not meet the demands.As one-sided adjusting, can look after setting again less than other parameters, bring very burden for manufacture craft and production control.These shortcomings have influenced common internal trigger and have jumped the fail safe of steeping in the use, have also directly influenced common jumping bubble as the application that starts trigger in the high-pressure sodium lamp.

Summary of the invention

The utility model provides between the bimetal leaf contact because of contact resistance generates heat, and the hot melt state can not occur, is difficult for adhesion, and bubble is jumped in a kind of high-pressure sodium lamp internal trigger that does not also just influence sheet metal moment breaking speed.

The technical scheme that the utility model is taked: in the glass stem assembly, draw sealing-in silk with the coefficient of expansion, the inner bimetal leaf that is welded with seal wire and introversion successively, place in the inert gas filled cell-shell sealing shape, its scheme is: the inboard two-end-point at two close bimetal leafs respectively is welded with the contact that contains silver metal.

Good effect of the present utility model is: because silver metal fusing point height, hardness height, fast, the physical characteristics such as resistivity is low of conducting heat, two contacts the hot melt state can not occur during work, adhesion, so disjunction is rapid, improved the hot melt adhesion phenomenon to greatest extent, jumped the superior function that bubble starts high-pressure sodium lamp thereby given full play to internal trigger.

Fig. 2 is the utility model embodiment side structure schematic diagram.

Fig. 3 is the utility model Application Example diagram.

Embodiment

Now the utility model is described in further detail in conjunction with the accompanying drawings

Bubble is jumped in the high-pressure sodium lamp internal trigger, and by the sealing-in silk 5 of drawing in the glass stem assembly 6 with the coefficient of expansion, exit is welded with the bimetal leaf 3 of seal wire 4 and introversion successively, places in the inert gas filled cell-shell 1 the sealing shape; Its structure is: at two close bimetal leafs, 3 inboard two-end-points, respectively be welded with the contact 2 that contains silver metal.

Fig. 3 is the utility model application example diagram.The two ends that bubble is attempted by polycrystalline alumina ceramic arc pipe are jumped in the internal trigger of high-pressure sodium lamp, in polycrystalline alumina ceramic arc pipe is in the quartz glass outside bulb shell of vacuum.

Each parts effect of the utility model: filling with inert gas in the glass tube, neon or argon gas have ensured the operational environment and the necessary condition of bimetal leaf; The bimetal leaf active layers has the different coefficients of expansion with passive layer, bends when being heated; Contain silver contact and can improve bonding phenomenon to greatest extent; The sealing-in silk is close with the glass swelling coefficient, is convenient to sealing-in and is unlikely to gas leakage.

Now the high-pressure sodium lamp internal trigger is jumped course of work do one explanation of bubble: after connecting with the mains, inert gas in the jumping bubble produces glow discharge and generates heat, temperature rising in the glass bulb, bimetal leaf heated bending closure, contact by the contact, glow discharge disappears, and temperature descends in the glass bulb subsequently, and the bimetal leaf cooling restores to the original state, disconnect rapidly by the contact, ballast produces induced voltage, and this voltage and external power voltage are added on the polycrystalline alumina ceramic arc pipe simultaneously, open bright sodium vapor lamp.

Claims

1, bubble is jumped in the high-pressure sodium lamp internal trigger, be included in the glass stem assembly (6), draw sealing-in silk (5) with the coefficient of expansion, the inner is welded with the bimetal leaf (3) of seal wire (4) and introversion successively, place in the inert gas filled cell-shell (1) the sealing shape, it is characterized in that:, respectively be welded with the contact (2) that contains silver metal at the inboard two-end-point of two close bimetal leafs (3).
