Description

The novel illumination fluorescent lamp

[technical field]

The utility model relates to lighting field, refers in particular to a kind of novel illumination fluorescent lamp.

[background technology]

Household illuminating lamp generally all uses fluorescent tube to do illumination at present; This fluorescent tube is by a glass tube of under vacuum condition, being made up of certain hydrogen and a spot of mercury; Inwall at glass tube scribbles fluorescent material, and the electrode that the two ends of glass tube respectively are made up of two tungsten filaments scribbles the material that the emission electronics is arranged after one deck heats on tungsten filament; Send ultraviolet ray during gaseous conduction between two filaments, make phosphor powder send visible light.Conventional general fluorescent lamp work characteristics: need a high voltage when fluorescent tube begins to light, normally only allow through little electric current when luminous, at this moment the voltage of lamp tube ends is lower than supply voltage.

As shown in Figure 1, after common fluorescent lamp place in circuit, begin glow discharge between 10 two electrodes of starter; Make the bimetal leaf expanded by heating and contact with the stationary contact utmost point, so filament and starters 10 in the power supply, ballast 20, fluorescent tube 30 constitute a closed-loop path, electric current makes filament pre-heating; As heated time 1-3 after second, two interelectrode glow discharges of starter are extinguished, thereupon the bimetal leaf cooling and break off with the stationary contact utmost point; When the moment that two electrodes break off, the electric current in the circuit suddenly disappears, so ballast produces a high-voltage pulse; After the stack of it and power supply, be added to lamp tube ends, make the ionized inert gas in the fluorescent tube and cause arc discharge; In normal luminescence process, the self-induction of ballast also plays a part electric current in the stabilizing circuit.Inductive ballast is an iron inductance coil, and the character of inductance is when the electric current in the coil changes, and then in coil, will cause the variation of magnetic flux, thereby produces induced electromotive force, and its direction and sense of current are opposite, thereby hampers the electric current variation.Starter plays on-off action in circuit, it is formed in parallel by a neon discharge tube and an electric capacity, and the elimination that act as of electric capacity forms the soup loop that shakes to the interference of the electromagnetism of power supply and with ballast, increases the starting impulse voltage amplitude.An electrode is formed with bimetal leaf in the discharge tube, utilizes neon bulb discharge heating, makes bimetal leaf when opening and closing, and causes the Inductive ballast current break and produce high-voltage pulse to be added to lamp tube ends.Traditional fluorescent lamp (Inductive ballast) actual power consumption is about 53W, and 40W traditional fluorescent lamp (Inductive ballast) actual power consumption is about 68W.

Based on the existing structure of above-mentioned traditional fluorescent lamp, this kind fluorescent lamp has following shortcoming: contain a large amount of mercury vapours in traditional fluorescent lamp, if broken mercury vapour then can evaporate in the atmosphere contaminated environment; Traditional fluorescent lamp can produce a large amount of heat energy, causes the waste of the energy, and conversion ratio is low, and can be produced the phenomenon of fading by the file of long-term irradiation, clothing; The traditional fluorescent lamp noise is bigger, and can produce stroboscopic, influences user's eyesight, the alternating current of its use, and can produce 100-120 time stroboscopic each second; Traditional fluorescent lamp can produce ultraviolet ray, has a lot of mosquitoes like this and is centered around by the lamp source, influences indoor health; The traditional fluorescent lamp life-span is short, changes frequently, damages easily, and quality is unstable, and use cost is high; Anti-vibration resistance is poor, and the cost of transportation excessive risk is high.

[summary of the invention]

The purpose of the utility model is that a kind of good illumination effect is provided, the life-span is long, brightness is high, the novel illumination fluorescent lamp of energy saving.

For realizing the utility model purpose, following technical scheme is provided:

The utility model provides a kind of novel illumination fluorescent lamp, and it comprises the LED fluorescent tube that connects power supply, and is connected the full bridge rectifier between power supply and the LED fluorescent tube.The utility model novel illumination fluorescent lamp is to adopt the LED white light as illuminating source, good illumination effect, and energy-conservation, the life-span is long, and applicability is good.

Preferably, between this full bridge rectifier and power supply, be connected with EMC wave filter (EMC, Electro Magnetic Compatibility Electro Magnetic Compatibility).

Preferably, between this full bridge rectifier and LED fluorescent tube, be connected with PFC circuit of power factor correction (PFC, Power Factor Correction).
