Abstract
The invention provides a method for manufacturing a bulb without seal head trace for a high-energy electric light source. The traditional bulb processing method is improved. The invention is characterized in that when the bulb blank is manufactured, a pore channel is reserved on the blank for exhausting, inflating and charging, the sealing of the bulb or the fixing of the electrode is carried out under the negative pressure, so that the whole reserved pore channel glass is melted and the pore channel is blocked, and the manufactured bulb has beautiful appearance, better quality and longer service life.
Description
The present invention relates to the electric light source technology for making lamp bulb.
Traditional technology for making lamp bulb comprises: the making of bulb germule, the cleaning of germule and oven dry, vacuum degassing, filling working media and auxiliary material, put into electrode, connect a special-purpose steam vent at other position of bulb and carry out end socket, add lamp holder etc.The bulb of making so always has the end socket vestige to exist, and outside outstanding being exposed to that has, influences the outward appearance of lamp; The inside of the plant lamp holder that has makes the processing of lamp holder increase difficulty.The indent of end socket and evagination can cause luminous inhomogeneous and unstable in high energy electric light source such as electrodeless microwave sulfur lamp, and damage easily.Along with the generation and the development of high energy light source and new type light source such as microwave sulfur lamp etc., a kind of making exquisiteness, good, the no end socket vestige of property, rotatable high-quality bulb manufacturing technology have been mentioned the discussion process symmetrically.
The purpose of this invention is to provide a kind of no end socket vestige technology for making lamp bulb.
Technical scheme of the present invention is to realize like this.
A kind of technology for making lamp bulb that does not have the end socket vestige, contain the following step: the oven dry of the making of bulb germule, the cleaning of germule, germule, filling working media and auxiliary material are put into electrode, are vacuumized, fixed electrode, seal etc.The difference of manufacture method of the present invention and conventional method is: reserve a hole in advance when making the bulb germule, be used for exhaust, inflation, charging; Carry out essence envelope under negative pressure, i.e. sealing of the fixing and bulb of electrode makes the reserving hole channel inwall melt and blocks passage (if any electrode, this moment, electrode also together was fixed on heart position, hole), so just made the bulb of no end socket vestige.
The bulb of according to said method producing does not have the end socket vestige, can make that good looking appearance, the electrode of bulb is fixing better, lamp holder is installed more convenient.The present invention is particularly useful for the making of microwave sulphur lamp bulb, makes bulb quality higher, rotates more stablely, and the life-span of bulb is longer.
Below in conjunction with drawings and Examples the present invention is further detailed.

A kind of technology for making lamp bulb of the present invention is like this preparation. At first, produce needed bulb germule, the bulb germule is reserved in advance a reserving hole channel 7 and is used for exhaust, inflation, charging; Clean then germule and oven dry, after the germule oven dry, filling working media and auxiliary material are put into electrode in reserving hole channel 7, are connected with vacuum system then, vacuumize; When being vented to the scope of certain numerical value, bulb carries out just envelope on vacuum system, just is honored as a queen, and bulb from taking off in vacuum system, and is guaranteed vacuum in the bulb; Then the bulb of just sealing is reprocessed, namely under negative pressure, carry out the essence envelope, so that reserving hole channel 7 inwalls melt and block passage (if any electrode, this moment, electrode also together was fixed on heart position, hole), so just made the bulb of no end socket vestige.
Embodiment 1
The preparation of microwave sulphur lamp bulb.As Fig. 1, Fig. 2, shown in Figure 3, select for use silica glass material to produce the bulb germule; Germule is reserved a duct 7 in advance and is used for exhaust, inflation, charging, cleans germule and oven dry then, and the luminescent material of packing into connects vacuum system from ground 1 and carries out exhaust; Be vented to vacuum degree and be higher than 10
-2During Pa, charge into argon gas, in envelope 2 places, position heating just, carry out envelope just then, take off the bulb of just sealing (Fig. 2); Under negative pressure, the bulb just sealed is carried out sealing second time at essence envelope 3 places, position, promptly smart envelope, make whole reserving hole channel 7 inwalls the glass thawing and shut the duct, form solid glass column, just made required microwave sulphur lamp bulb.
The laboratory preparation of nitrogen lamp bulb.As Fig. 4, Fig. 5, shown in Figure 6, select for use hard glass to produce the bulb germule, germule is reserved a duct 7 in advance and is used for exhaust, inflation, charging, clean germule and oven dry then, wash down with inert gas, put into tungsten electrode 5, in advance with one deck bead 6, connect vacuum system from the ground 1 of bulb germule and carry out exhaust on the tungsten electrode; Be vented to vacuum degree and be higher than 10
-1During Pa, charge into nitrogen, in envelope 2 places, position heating just, carry out envelope just then, take off the bulb of just sealing (Fig. 5); Under negative pressure, the bulb of just sealing is carried out sealing the second time at essence envelope 3 places, position, promptly smart envelope and fixed electrode, feasible glass herein melts and shuts reserving hole channel 7, is formed with the nitrogen lamp bulb of two electrodes.
The electroded bulb that adopts method of the present invention to make, owing under vacuum condition the electrode in the bulb is fixed, metal electrode can be not oxidized in the bulb course of processing, and electrode uses operating state more stable, and the life-span is longer.Method of the present invention is carried out sealing of twice bulb under negative pressure, easy operating and assurance precision; Also can adopt and once seal shaping.
