Description

Baby energy-saving lamp tube

The utility model is that a kind of power is 2 watts to 6 watts little electric current low power energy-saving lamp pipe, belongs to a kind of lower-powered pre-heated highly effective fluorescent tube.

Electricity-saving lamp is also referred to as the compact high efficient fluorescent lamp, and the maximum characteristics of this lamp are to have the compact structure of high light efficiency, high-color rendering energy and fluorescent tube.It can resemble the incandescent lamp bulb commonly used and use easily, has incandescent lamp bulb good color rendering like that, and it is incomparable to have incandescent lamp bulb simultaneously, is incandescent lamp bulb about four times luminous efficiency and working life.Replace incandescent lamp with electricity-saving lamp, generally can economize on electricity 75%.

Yet, there is at present a problem in the electricity-saving lamp product line, it is less that promptly 7 watts, 5 watts power saving fluorescent lampss are used, and is lower than 5 watts the product that do not have, and domesticly commonly used mostly is 9 watts, 11 watts, 16 watts three kinds.Reason is that the fluorescent tube light efficiency that power is more little in the existing electricity-saving lamp series is low more, and the power consumption on the ballast of adapted increases on the contrary, complete to make the total light efficiency of lamp with power of lamp tube reduce and decline significantly.For example, 11 watts of about 700 lumens of power saving fluorescent lamps luminous flux, the fluorescent tube light efficiency is every watt 64 lumen approximately, about 3 watts of ballast loss, totally 14 watts of full lamp power consumptions, the complete total light efficiency of lamp is every watt 50 lumen approximately.And 5 watts of power saving fluorescent lampss of power minimum, about 200 lumens of luminous flux, fluorescent tube light efficiency are every watt 40 lumen approximately, ballast power consumption often is 5 watts, 10 watts of then full lamp total power consumptions, total light efficiency is about every watt 20 lumen, than the former light efficiency decline 60%! Not hard to imagine, the power saving fluorescent lamps light efficiency below 5 watts will be lower and have practical value.

The purpose of this utility model is the structure redesign to power saving fluorescent lamps, make the power saving fluorescent lamps below 5 watts and 5 watts can be near the light efficiency of 11 watts of power saving fluorescent lampss, and the power consumption of ballast is also similar has only 1/3 to 1/4 of fluorescent tube power consumption, and the promptly complete total light transmittance efficiency of lamp reaches every watt 40 to 50 lumen.Like this, 5 watts of electricity-saving lamps that power saving fluorescent lamps is formed, total power consumption is 6.3 watts of luminous fluxes that can produce near 40 watts of bulbs; 4 watts of electricity-saving lamps that power saving fluorescent lamps is formed, about 5 watts of total power consumption can be equivalent to 25 watts of bulbs; 3 watts of power saving fluorescent lampss can be equivalent to or surpass the illumination of 15 watts of bulbs.So high light efficiency low power energy-saving lamp is dropped into China huge numbers of families, will produce very considerable power savings.

Below in conjunction with description of drawings the utility model.

Fig. 1 is first kind of structural representation of small power energy-saving fluorescent tube.

Fig. 2 is second kind of structural representation of small power energy-saving fluorescent tube.

With reference to Fig. 1, Fig. 2, the utility model is the same with existing power saving fluorescent lamps, is made up of glass lamp 1, the filament electrode 3 that is applied to the triphosphor Fluorescent Powder layer 2 of tube inner wall and is loaded on the glass-tube two ends respectively.Be filled with mercury vapour and an amount of argon (or argon, krypton mix) gas in the fluorescent tube.Characteristics of the present utility model be adopted interior caliber be 6 to 8 millimeters fluorescent tube, form filament the tungsten filament diameter very thin, it only is 15 microns to 25 microns, and filament electrode is novel combination filamentray structure, being filament electrode is combined by two or two above filaments, is divided into preheating filament and non-preheating filament two parts.The said structure feature is descended the rated operational current of electricity-saving lamp significantly, 2 to 6 watts lamp current can be designed to 30 milliamperes～80 milliamperes, improved the light efficiency of low power energy-saving lamp pipe effectively, reduced the power consumption of matched Inductive ballast, the total light efficiency of full lamp is increased substantially.

From the principle of fluorescent lamp as can be known, the region of discharge of fluorescent lamp is broadly divided into cathode fall district, positive column and anode fall district three parts.Wherein negative electrode and anode fall district are collectively referred to as electrode potential drop district, and the power that this zone consumed is mainly used in to produce keeps the required charged particle of gas discharge---cation and electronics in the pipe, less to the lamp luminescence contribution; The power that the positive column consumes except that the loss and heat producing losses of supplementary copy zone charged particle, its a part of power be used to produce required ultraviolet radiation and excitated fluorescent powder luminous.Thereby the positive column is to make the main luminous region of discharge of fluorescent tube, so the power of positive column accounts for the size of full lamp power proportions, is directly connected to the light efficiency of fluorescent tube.Little electric current electricity-saving lamp is because electric current is reduced to about 1/3rd of common energy-saving lamp, then the tube voltage drop raising with the power fluorescent tube is about 3 times, and the pressure drop in electrode potential drop district can be similar to think 17.5 volts constant, so luminous positive column voltage drop is increased substantially, the ratio that positive column power accounts for power of lamp tube strengthens thereupon, and the fluorescent tube light efficiency is greatly improved.In addition, what reduce at double and the light tube electric voltage of electric current fell increases, and the apparent power of matched Inductive ballast is descended significantly, the also corresponding reduction of its power consumption (being 0.8 watt to 1.4 watts).Above-mentioned is exactly that the utility model can make small power energy-saving light imitate the reason that increases substantially.

For the lamp works life-span was reached more than 3000 hours, filament electrode adopts the combination filamentray structure of the utility model uniqueness.Because if adopt and the similar single filament structure of common energy-saving lamp, lamp tube service life too carefully generally has only about 300 hours because of filament, this obviously is not all right.

The combinations thereof filament has two kinds of combining forms.With reference to Fig. 1, in first kind of combination, the tungsten filament diameter of all filaments is identical, and the coiling of filament and the situation of applying electronic powder are just the same, and the front and back filament is connected in series.Link of filament is welded on the same fixed lever before and after this, has lead-out wire to draw; In addition, the end of the top of first filament and last root filament all is welded in separately on the corresponding fixed lever, has lead-out wire to draw respectively.Like this, the filament electrode that is combined by two filaments has three lead-out wires; By what three filaments were formed four lead-out wires are arranged, so analogize.But, generally form enough by two filaments.

With reference to Fig. 2, each filament can be different in second kind of combination, and the tungsten filament diameter, coiling and the dusting situation that form filament can be different, and two end points of every filament all are welded in separately on the corresponding fixed lever, have lead-out wire to draw respectively, promptly each filament does not connect in pipe.The filament electrode of being made up of two filaments has four independently lead-out wires like this, by what three filaments were formed six roots of sensation lead-out wire is arranged, and so analogizes.Generally form enough by two filaments.

When fluorescent tube was connected with operating circuit, the top lead-out wire a of first filament A of two filament electrodes should be connected with starter, and filament A is preheating filament.Be connected with the circuit that leads to power supply again behind the terminal lead-out wire of this root preheating filament A and the whole short circuits of all lead-out wires of other filaments.Like this, the two ends of other all filaments except that preheating filament A are the lead-out wire short circuit, are non-preheating filament.As seen, the feature of this combination filament electrode, essence are the non-preheating filament that is provided with the lead-out wire short circuit.The setting of non-preheating filament can significantly reduce the working temperature of filament, alleviates the evaporation loss of filament active material greatly, the working life that has prolonged fluorescent tube very effectively.Second kind of combining form can make non-preheating filament than preheating filament thick (design of preheating filament must adapt with the fluorescent tube preheat curent, overstriking arbitrarily), and the electronics powder that comprises can be more, can make lamp tube service life longer like this.But this moment the filament heating line of exhaust air technique and exhaust schedule with corresponding complexity some.

It is close with common energy-saving lamp to consider that fluorescent tube scribbles the inwall load of fluorescent material, and the fluorescent tube internal diameter of 2 to 6 watts little electric current electricity-saving lamp is elected 6 to 8 millimeters as; Fluorescent tube discharge path length is 160 millimeters to 260 millimeters; The rated voltage of fluorescent tube is reduced to 80 volts to 120 volts, to guarantee higher fluorescent tube light efficiency.

Replace 15 to 40 watts of bulbs with the utility model, economize on electricity is more than 80% under the identical situation of luminous flux.Compare with common energy-saving lamp in addition, the electricity-saving lamp of forming with 5 watts of fluorescent tubes is an example, and the utility model doubles to more than one times than the total light efficiency of common energy-saving lamp, and cost descends 1/3rd approximately, and weight and volume reduce about 1/2nd.

The utility model can be widely used in indoor general lighting and desk lamp, wall lamp, pendent lamp.It is worthy of note, when using it for battery powered portable lamp and emergency light, also more practical than miniature bulb and common energy-saving lamp.
