Abstract
The invented technique for manufacturing circle fluorescent lamps includes following working procedure flow: the bepowdering, the baking tube, the sealing, the bending tube, the exhausting air, the putting head and the aging. In the sealing procedure, two end parts seal the two lamp cores with two holes on each core respectively. In the bending tube procedure, nitrogen gas or argon gas is passed over the vent-tube on the lam pcore on the one end, and vented from the vent-tube on the lamp core on the other end. The gas is circulated in the tube and the two ends, rinsing the other gases of impurities. Thus, the temperature in the tube is adjusted, and the coat of the luminescent powder gets the good protection. The invented circle fluorescent lamps decrease the light attenuation and increase the luminous flux.
Description
＜technical field 〉
Technical solution of the present invention belongs to a kind of production process of ring fluorescence discharge lamp.
＜background technology 〉
In existing production process of ring fluorescence discharge lamp, the general technology flow process is: dusting → roasted tube → seal → bend pipe → exhaust → mounted head → seasoned.Wherein at sealing process, be with an atresia wick and the porose wick of another respectively with glass-tube two end sealing-ins, make that the space only communicates with ambient atmosphere by the blast pipe in the wick in the pipe; In the bend pipe operation, be the fluorescent tube thermoplastic on heating furnace after sealing, again glass-tube bent to annular, also must constantly in pipe, charge into nitrogen or argon gas simultaneously by the blast pipe in the porose wick, with protection negative electrode and the not oxidation of seal wire pin, and make the slick and sly rule of the fluorescent tube of bending; At deairing step, be the vacuum system that fluorescent tube is inserted air exhauster, bleed then, part degass, cathode disintegration and activation, charge into inert gas, fill mercury and with the fluorescent tube sealed-off.
＜summary of the invention 〉
In above-mentioned existing production process of ring fluorescence discharge lamp, fluorescent tube one end sealing-in be the atresia wick.In the bend pipe process, the nitrogen or the argon gas of protection usefulness can only single-endedly feed from the blast pipe of the porose wick of fluorescent tube, and described protective gas can not reach the circulation of two ends in pipe; its protection effect is relatively poor; fluorescent coating and negative electrode still are subjected to bigger infringement, cause the circline light decay big, and light efficiency is low.
Technical scheme of the present invention is: a kind of production process of ring fluorescence discharge lamp, and comprise dusting, roasted tube, seal, bend pipe, exhaust, mounted head, seasoned process flow, in the dusting operation, phosphor suspension is coated to securely on the inwall of glass-tube; In the roasted tube operation, by heated baking, binding agent and solvolysis in the fluorescent coating are eliminated the glass-tube after the dusting; At deairing step, fluorescent tube is inserted air exhauster and bleed, part degass, cathode disintegration and activation, charge into inert gas, fill mercury and sealed-off; In the mounted head operation, lamp holder is installed on the fluorescent tube termination; In seasoned operation, the burning-point fluorescent tube carries out seasoned, particularly at sealing process, with two porose wicks respectively with glass-tube two end sealing-ins, make that the blast pipe of space by the porose wick of two ends communicates with ambient atmosphere in the pipe; In the bend pipe operation, earlier with the fluorescent tube thermoplastic, simultaneously nitrogen or argon gas are charged in the pipe, its gas reaches the circulation of two ends in pipe, after fluorescent tube is softening, block the exhaust outlet of the porose wick of gas outlet side, and fluorescent tube is bent to annular, after the fluorescent tube hardening by cooling, the blast pipe with the porose wick of fluorescent tube one end seals again.
In the technical solution of the present invention; fluorescent tube two end sealing-ins all be porose wick; two blast pipe apertures can be identical, and in the bend pipe operation, the nitrogen of feeding or argon gas can reach the circulation of two ends in pipe; its gas pressure intensity is 0.5～1 atmospheric pressure; therefore temperature in the pipe is regulated, and other objectionable impurities gas in the pipe is all washed, and fluorescent coating, negative electrode and seal wire pin have obtained better protection; make the light decay index of circline reduce, luminous flux improves.
＜embodiment 〉
A kind of production process of ring fluorescence discharge lamp, comprise dusting, roasted tube, seal, bend pipe, exhaust, mounted head, seasoned process flow, in the dusting operation, choosing is thrown light on halogen calcium phosphate fluoressent powder or rare-earth trichromatic fluorescent powder, phosphor suspension is coated to securely on the inwall of glass-tube by spraying process, powder layer thickness is 5-10mg/cm
2In the roasted tube operation, by electric heating or muffle thermal radiation heated baking, baking temperature is 450～550 ℃ with the glass-tube after the dusting, and binding agent and solvolysis in the fluorescent coating are eliminated; At sealing process, two porose wicks that the exhaust caliber is identical respectively with glass-tube two end sealing-ins, make that the blast pipe of space by the porose wick of two ends communicates with ambient atmosphere in the pipe; In the bend pipe operation, by manual bend pipe mode with fluorescent tube thermoplastic in heating furnace, connect also by plastic hose simultaneously and constantly nitrogen or argon gas are charged into from the blast pipe of the porose wick of fluorescent tube one end, then discharge gas in the blast pipe of the porose wick of the fluorescent tube other end, its gas reaches the circulation of two ends in pipe, gas pressure intensity is 0.5～1 atmospheric pressure, after fluorescent tube is softening, with the manual porose wick exhaust outlet of blocking the gas outlet side, and with the manual annular that bends to of fluorescent tube, after the fluorescent tube hardening by cooling, the porose wick blast pipe with fluorescent tube one end seals again.At deairing step, fluorescent tube is inserted air exhauster and bleed, behind the cathode disintegration and activation, charge into inert gas, fill mercury and sealed-off; In the mounted head operation, lamp holder is installed on the fluorescent tube termination; In seasoned operation, the burning-point fluorescent tube carries out seasoned.
The technology of the present invention can be applicable on the automation equipment production technology. Particularly be fit to manual adding The worker produces circline, compares with conventional fabrication processes, and the light decay of this circline can fall Low by 5%, luminous flux can improve 8-9 (lm/ watt), and effect is remarkable.
