Abstract
The utility model relates to an inner-trigger high-voltage sodium lamp, which belongs to the technical field of an inner trigger used by the inner-trigger high-voltage sodium lamp. The inner trigger of the high-voltage sodium lamp of the utility model comprises an insulator 11 and a bimetal sheet 4, wherein the insulator 11 forms a step type and all glass enamel welding spots are on the same direction. The inner trigger of the utility model makes all glass enamel welding spots designed on the same plane, optimizes the structure, only needs one-time burning enamel, simplifies the factory processing operation and enhances the production yield.
Description
Technical field
The utility model relates to the internal trigger field of internal trigger high-pressure sodium lamp and use thereof.
Background technology
Because high-pressure sodium lamp can not be adorned auxiliary electrode as other gaseous discharge lamp, must trigger with high-voltage pulse.Adorn one " automatic switch " in lamp, utilize the reverse potential in the choking-winding to trigger bulb, such high-pressure sodium lamp is called the internal trigger lamp.The internal trigger structure of internal trigger lamp is a lot, wherein a kind of is to utilize supply voltage to add thrermostatic bimetal-plate, immediate current in the bimetal leaf tripping is zero, because the coil of ballast has holding current constant characteristic continuously, suddenly interrupted so work as electric current, voltage can sharply rise, and this voltage has been added on the electric arc tube of high-pressure sodium lamp, make gas produce discharge, this pulse voltage starts lamp.After lamp started, bimetal leaf kept open-circuit condition.Existing this high-pressure sodium lamp internal trigger structure is seen Fig. 1, Fig. 2 and Fig. 3, and Fig. 1 is a front view, and Fig. 2 is a vertical view, and Fig. 3 is its left view.Though thisly directly utilize supply voltage to add thrermostatic bimetal-plate to have come the internal trigger of on-off action simple in structure, but the glass porcelain glaze solder joint of its insulator 1 is on rectangular two faces, be front glass enamel solder joint 2 and upper glass enamel solder joint 3, in preparation process, need twice gloss firing like this, very easily leak glaze, make the superstructure loosening of trigger, reliability reduces.
Summary of the invention
The purpose of this utility model provides a kind of not only simple in structure and easy high-pressure sodium lamp internal trigger of preparation method.
Another purpose of the utility model provides a kind of high-pressure sodium lamp that uses above-mentioned internal trigger.
A kind of high-pressure sodium lamp internal trigger comprises insulator and bimetal leaf, and wherein said insulator is a step, comprise same towards two planes, and all glass porcelain glaze solder joints are evenly distributed on these two faces.
High-pressure sodium lamp internal trigger described in the utility model, its bimetal leaf 4 is a curved shape.
The utility model has made the plate insulator of high-pressure sodium lamp internal trigger into the structure of step, and all glass porcelain glaze solder joints, be that upper glass enamel solder joint and lower-glass enamel solder joint are on two faces of the same direction of step insulator, during preparation the operation that will carry out twice gloss firing originally is merged into one procedure, has avoided disadvantages such as leakage glaze that twice gloss firing produce, connection loosing.
A kind of high-pressure sodium lamp, used internal trigger are above-mentioned internal trigger.
The beneficial effects of the utility model: the said internal trigger of the utility model all designs all glass porcelain glaze solder joints in one plane, has optimized structure, only needs a gloss firing, has simplified production process and has improved product percent of pass.

Fig. 7 is that internal trigger described in the utility model is assemblied in the schematic diagram in the lamp.
Embodiment
As shown in Figure 4, step-like ceramics insulator 11 is an internal trigger main body described in the utility model, the first vertical view hole 6 shown in Figure 5 that the good bimetal leaf 4 of welding and molybdenum rod lead-in wire 5 are passed internal trigger, then fixed lever 7 is inserted side opening 8 shown in Figure 6, hole and following face in the above then, be to irritate the upper glass glaze in the hole at local place of upper glass enamel solder joint 10 and lower-glass enamel solder joint 9, send into the stove sintering, hole and the burned glass porcelain glaze in following face place are exactly foregoing upper glass enamel solder joint 10 and lower-glass enamel solder joint 9 in the above.So only need a gloss firing just can prepare the same higher internal trigger of simple and up-to-standard rate of structure.
High-pressure sodium lamp internal trigger described in the utility model comprises insulator 11 and bimetal leaf 4, and insulator 11 is step, comprise same towards two planes, all glass porcelain glaze solder joints are evenly distributed on these two faces.
High-pressure sodium lamp internal trigger described in the utility model, the shape that its bimetal leaf 4 flexible one-tenth need.
As shown in Figure 7, one end of the fixed lever 7 of internal trigger described in the utility model is connected with the termination 12 of high-pressure sodium lamp discharge tube, the other end is connected with main support 13, then two pin of molybdenum rod lead-in wire are connected on main support 13 and the wick inner guide wire 14, at last multiply copper seal wire 15 are connected on the fixed lever 7 of electric arc tube termination.When voltage was connected with the mains at the two ends of internal trigger, bimetal leaf was heated tripping, produces a high-voltage pulse simultaneously lamp is started.Lamp starts the back owing to thermal-radiating effect, and bimetal leaf keeps open-circuit condition.Lamp extinguishes back bimetal leaf cooling, recovers original state.
Result of the test proves, it is fine that internal trigger described in the utility model is applied on the high-pressure sodium lamp effect.
