Abstract

The invention discloses a production process for energy-saving amalgam lamps, which comprises the steps of powder tube processing, sealing, air exhausting, tail tube processing, detecting and packaging and the like, wherein in the step of sealing, a pre-flattened tail exhaust tube is adopted, an air channel at the flattened part of the tail tube of a lamp tube is kept unimpeded, and the size of a pore on the flattened part is less than the contour dimension of low-temperature amalgam; in the process of air exhausting, the low-temperature amalgam is filled in the lamp tube from the end part of an opening of the tail tube; after the air exhausting of the lamp tube is completed, the outer side of the tail tube filled with the low-temperature amalgam in the process of air exhausting is subjected to vacuum melting-seal cutting, and the low-temperature amalgam is located between the flattened part and a sealing opening of the tail tube; and after the cutting is completed, the inner side of the tail tube (at which the low-temperature amalgam is placed) is subjected to flame-softening shaping, so that the position (for placing the low-temperature amalgam) of the tail tube subjected to shaping is located in a low-temperature area of the lamp tube. The production process disclosed by the invention has the advantages that: according to the invention, an effect of replacing high-temperature amalgam with lower-temperature amalgam can be achieved, and the rise time index of the lamp tube can be greatly improved by using the characteristic that the lower-temperature amalgam produces a higher mercury vapor pressure at normal temperature.

Description

The production technology of amalgam electricity-saving lamp

Technical field

The present invention relates to a kind of production technology of compact type energy-saving lamp, particularly a kind of production technology of the electricity-saving lamp with amalgam.

Background technology

The 60% needed time that European Union's related standards regulation fluorescent tube reaches nominal light flux by the beginning burning-point is called the rise time of fluorescent tube.This numerical value is more little good more, and standard code is 120S (a band cover lamp).

After new standard was put into effect, this rise time requires can be stricter, may adjust to 110S and arrive 80% of nominal light flux.

Continuous aggravation along with industry competition; Whole lamp factory requires more and more harsher to the performance index of supporting fluorescent tube; Simultaneously, also demonstrate industry different processes level and quality condition, particularly exported to the lamp kind of American-European countries; Requirement to the fluorescent tube parameter is very high; A wherein very important rise time that index is exactly a fluorescent tube, because the quality of this index has produced very big competition situation, can become the big problem that fluorescent tube enterprise must pay attention between the different enterprises for the client provides the fluorescent tube product with very short rise time.

Along with the develop rapidly in electricity-saving lamp field, the market demand of various band cover lamps and reflector lamp kind is increasing.The traditional manufacturing technique basic configuration is that near the spot welding Auxiliary amalgam indium net sheet filament, tailpipe predeterminated position are placed the high temperature amalgam.Through behind the deairing step the unnecessary tail pipe glass outside the high temperature amalgam being cut away with pointed flame.For the fluorescent tube that satisfies under the airtight lampshade condition of high temperature has rational mercury vapor pressure, need increase substantially the working temperature of amalgam, utilize the temperature control characteristic of high temperature amalgam to reach corresponding purpose.But following, because the raising of amalgam temperature, the mercury vapor pressure that normal temperature can provide down becomes very low, and the rise time of fluorescent tube prolongs greatly, can not satisfy the harsh day by day market demand.

The processing technology that industry is general is not carried out any shaping to tail pipe, is just placing the outside flame cutting of amalgam on demand, and general tail pipe length is no more than 8mm.Such common processes means; Can not realize the purpose of high temperature in the outer low temperature control; Can only rely on the higher amalgam of temperature in the fluorescent tube tail pipe to come the Control work temperature to reach the purpose of the normal mercury vapor pressure of control, nature will bring long fatal disadvantage of fluorescent tube rise time.

Summary of the invention

Goal of the invention: the objective of the invention is in order to solve long defective of common amalgam electricity-saving lamp rise time; A kind of amalgam relative position in tailpipe and then the adjustment fluorescent tube of after exhaust is accomplished, adjusting is provided, realizes replacing the production technology of the amalgam electricity-saving lamp of high temperature amalgam with the amalgam of lower temperature.

Technical scheme: a kind of production technology of amalgam electricity-saving lamp; Comprise that tube cell is handled, sealed, exhaust, tail pipe processing, detection and packaging and other steps; Adopt the flat tailpipe of folder in advance during said sealing process; And it is unimpeded to keep the fluorescent tube tail pipe to press from both sides flat place gas circuit, and the flat place of said folder hole is less than the overall dimension of Low temp amalgam; Low temp amalgam is injected in end from the tail pipe opening in the exhaust process; After the fluorescent tube exhaust is accomplished vacuum is carried out in the tail pipe outside of having injected Low temp amalgam in the exhaust process and melt the envelope cutting, Low temp amalgam is between the flat place of folder and tail pipe seal; Cutting is accomplished the back flame softening shaping is carried out in the tail pipe inboard of placing Low temp amalgam, makes the position of the tail pipe placement Low temp amalgam after the shaping be positioned at the fluorescent tube low-temperature space.

Described Low temp amalgam is positioned is to adopt the method for tail pipe being pressed from both sides flat processing, and the flat method of said folder is that pointed flame heat tailpipe tube wall makes it softening, through the softening salient point that makes tail pipe tube wall assigned position form an indent of flame scorification.

Described Low temp amalgam is positioned is to adopt the method for tail pipe being pressed from both sides flat processing, and the flat method of said folder makes tube wall softening for the heating tube wall, makes tube wall form the salient point of at least two indents through anchor clamps.

Effective effect: the present invention can realize replacing the high temperature amalgam with the amalgam of lower temperature; The running parameter that had both guaranteed fluorescent tube meets design objective, and the characteristic that produces higher mercury vapor pressure under the normal temperature that can utilize the lower amalgam of temperature to have again increases substantially the rise time index of fluorescent tube.
