Description

The novel energy-conserving fluorescent lamp

The utility model relates to a kind of fluorescent lamp, relates in particular to a kind of novel energy-conserving fluorescent lamp, belongs to the lighting device technical field.

At present, the fluorescent lamp of selling on the market, or add starter with the iron core rectifier, or encourage lamp luminescence with electron rectifier.And add the fluorescent lamp of starter with the iron core rectifier, because of its have energy consumption big, stroboscopic arranged, have shortcoming such as noise to be eliminated gradually; Though the fluorescent lamp with electron rectifier has energy-conservation, no stroboscopic, muting advantage,, also caused the situation of very difficult listing because of it has complex circuit, cost height, the unsettled shortcoming of Electronic Performance.

The purpose of this utility model is to provide novel energy-conserving fluorescent lamp a kind of simple in structure, stable and reliable for performance.

The utility model is achieved in that a kind of novel energy-conserving fluorescent lamp, comprises lamp bracket, fluorescent tube, lamp base, is characterized in being serially connected with in two lamp bases direct current voltage multiplie, wherein is serially connected with the current limliting buffer between a lamp base and direct current voltage multiplie.

The utility model can also be achieved in that and fill hydrogen sulfide gas in fluorescent tube.

The utility model also can be achieved in that described lamp bracket both sides for parabolic, and its lamp bracket width is 3.5～4.0: 1 with the ratio of tube diameter; The lamp bracket width is 3.8～4.2: 1 with the ratio of the degree of depth.

Compare with existing plain edition fluorescent lamp, the utility model has been connected in series the direct current voltage multiplie in lamp base, and between a lamp base and direct current voltage multiplie, be connected in series a current limliting buffer, the change alternating current is direct current, directly provide the cold cathode emission source to fluorescent lamp, thereby overcome the shortcoming of iron core rectifier, kept the advantage of electron rectifier, have simple in structure, electric property is reliable and stable, non-impact current, no stroboscopic, volume is little, cost is low, the advantages such as long service life of fluorescent tube.

Fig. 1 is a general structure schematic diagram of the present utility model.

Fig. 2 is a circuit diagram of the present utility model.

Fig. 3 is the utility model current limliting buffer schematic diagram.

Fig. 4 is a side view of the present utility model.

Below in conjunction with accompanying drawing the utility model being done one describes in detail:

As Fig. 1, the utility model has removed the rectifier and the starter of common fluorescent lamp, directly provides the cold cathode emission source to fluorescent tube by times electrical equipment of the rectification in the lamp base 34, and this rectifier doubler is made up of durable elements such as diode and electrodeless electric capacities.Be no power consumption (small power consumption).Therefore, not only have energy-conservation (economize on electricity 30%～50%) effect, and have characteristics simple in structure, stable and reliable for performance.Owing to adopted the high direct voltage power supply, fundamentally eliminated stroboscopic, noise phenomenon.The light that fluorescent tube sends is soft, and particularly when extraneous supply voltage changed between 180V～240V, the DC voltage that is added to fluorescent tube two utmost points remained on about 140V, thereby the illuminance that fluorescent tube is sent is consistent substantially, and light remains soft.When external voltage 〉=180V, fluorescent tube can normal build-up of luminance.If in the low pressure area, when external voltage is reduced to 150V, to open the switch fluorescent tube and do not work, available hand is responded on fluorescent tube, gets final product build-up of luminance (attention can not touch power supply).Its operation principle such as Fig. 2, as seen from Figure 2, fluorescent tube is direct current supply, so as long as fluorescent tube is air tight, even if the fluorescent tube of fracture of wire also uses as usual, fluorescent tube is not fragile yet.

As Fig. 3, evenly annular current-limiting resistance 5 is a current-limiting resistance at interval, is again a good buffer.This current-limiting resistance is the critical component that is used for controlling by size of current, also is the vitals of economize on electricity.So-called economize on electricity is exactly the extraneous electric current of supplying with more little (under the condition that voltage is fixed), and the effect of economize on electricity is just good more, but the electric current that passes through is too little, then will influence the luminous quantity of fluorescent tube.By repetition test, for the 40W fluorescent lamp, when the resistance of current-limiting resistance during at 140 Ω, power savings the best, power savings can reach 50%.What is more important, the structure of this current-limiting resistance also are the partly crucial of control build-up of luminance moment impact electric current.When turning on light, the electric current that passes through slowly rises to setting equably, and fluorescent tube is lighted immediately, has eliminated the moment impact electric current when turning on light, and has prolonged the service life of fluorescent tube widely.Particularly this current-limiting resistance can be when extraneous supply voltage changes in 180V～240V scope, ohmically direct current pressure drop is controlled between 1.2V～5.4V, complementary mutually with the characteristic of rectifier doubler, reach when extraneous supply voltage changes, keep being added to the DC voltage of lamp tube ends on the level of 140V, this just fluorescent tube under the situation of extraneous voltage change, the constant substantially immediate cause of luminous maintenance of fluorescent tube.

The lamp bracket of Xiao Shouing is considered from angle magnificent, attractive in appearance for general in the market, has ignored the light visual angle, has occurred in effective illumination range of the same lamp, and having a long way to go of illumination makes eye fatigue easily, affects one's power of vision.The lamp bracket that the utility model adopts, by parabolic principle design, in the illuminance scope of regulation, the daylighting basically identical has kept eyesight preferably.Its operation principle as shown in Figure 4, lamp bracket 1 two sides are parabolic, its lamp bracket width AA is 136.8mm, tube diameter is Φ 36mm, the lamp bracket width is 3.8: 1 with the ratio of tube diameter; Lamp bracket depth B B is 32.4mm, and the lamp bracket width is 4: 1 with the ratio of the degree of depth.

The fluorescent tube that is equipped with in the utility model both can adopt fluorescent tube of supplying on the market or the waste and old fluorescent tube that does not leak gas as yet, also can adopt hydrogen sulfide gas to substitute the special fluorescent tube of mercury vapour.This special lamp tube is to charge into an amount of hydrogen sulfide gas again after the gas in the commercially available fluorescent tube is taken out to form.(can directly organize production by fluorescent tube factory in the future).This fluorescent tube has soft, the uniform characteristics of light, and the eye sense of natural daylight is arranged, and has eliminated the hidden danger of ultraviolet radiation, has protected people's eyesight preferably.
