Abstract

An LED (light emitting diode) fluorescent lamp capable of preventing electricity leakage comprises a lamp tube, a lamp panel and a radiator, wherein two ends of the lamp tube are respectively provided with a first end cover and a second end cover; and the positive and negative poles of the lamp panel are led out from the first end cover. The LED fluorescent lamp further comprises a grounding wire with one end being electrically connected with the radiator. As the radiator of the lamp tube is connected with the grounding wire, therefore the danger of electricity leakage of the lamp tube in the prior art can be eliminated.

Description

Anti-creeping LED fluorescent lamp

[technical field]

The utility model relates to lighting field, refers in particular to a kind of LED fluorescent lamp with earth connection.

[background technology]

Along with the LED broad application, the technology of LED daylight is day by day ripe, and begins to drop into commercial the use; Variation has taken place with respect to fluorescent tube power supply the principle in the past in existing LED fluorescent-lamp tube, and two electrodes of former each end cap of fluorescent tube are respectively live wire and zero line, and two conducting terminals of the present same end of fluorescent tube are same electrode; Can start to exchange fire line or zero line; The two ends of whole fluorescent tube are divided into the live wire and the zero line of civil power, and constant-current supply all is built in the two ends of fluorescent tube mostly, and constant-current source is in order to eliminate electromagnetic interference; The Y electric capacity that absorbs the electromagnetism clutter all is installed; Y electric capacity is absorbing the electromagnetic certain energy that stores simultaneously, and and the fluorescent tube radiator between form induced electromotive force, therefore on the radiator of fluorescent tube, have certain alternating current; Alternating current through on the test radiator maintains between the 20V to 30V; If city's electro-mechanical wave is bigger, the induced electromotive force on the fluorescent tube radiator is just stronger, so there is the danger of electric leakage in this LED fluorescent tube of the prior art.

Therefore, people are badly in need of having that a kind of to solve the electric leakage that LED daylight exists in the prior art dangerous, can thoroughly eliminate electric shock hidden danger, LED fluorescent lamp simple in structure.

[summary of the invention]

The utility model purpose provides a kind of LED fluorescent lamp that can eliminate electric shock hidden danger.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:

A kind of anti-creeping LED fluorescent lamp, it comprises fluorescent tube, lamp plate, constant-current supply and radiator, and fluorescent tube comprises first end cap and second end cap, it is characterized in that, and it further comprises the earth connection that an end is electrically connected with radiator.

The other end of earth connection can adopt the different technologies scheme to draw, and for example: this earth connection other end stretches out from first end cap, and second end cap is a sealed end.

Perhaps, this earth connection other end stretches out from first end cap, stretches out a pair of conductive pole of serial connection each other simultaneously on second end cap.

Or, also be provided with ground terminal on first end cap, the ground terminal that this earth connection link covers.

This earth connection other end can also stretch out from second end cap.

This anti-leakage structure can be applied in general LED fluorescent lamp, also can be applied in the LED fluorescent lamp of single-ended conduction, and the lamp plate both positive and negative polarity of the LED fluorescent lamp of this single-ended conduction is only drawn from first end cap, and second end cap is a sealed end.

The contrast prior art the utlity model has following advantage:

Because the utility model has connected earth connection on the fluorescent tube radiator, therefore can cross the danger of eliminating fluorescent tube electric leakage of the prior art.

[specific embodiment]

Shown in Fig. 1～4; The anti-creeping LED fluorescent lamp of the utility model comprises fluorescent tube 1, lamp plate 12 and radiator 2, and lamp tube ends is first end cap 3 and second end cap 4, and the both positive and negative polarity of lamp plate is drawn from first end cap 3; Anode and cathode

conductive terminal

31,32 as shown in the figure; This fluorescent lamp further comprises the earth connection 5 that an end is electrically connected with radiator 2, and earth connection 5 other ends stretch out from first end cap 3 in embodiment illustrated in fig. 1 one, and second end cap 4 is a sealed end.

See also Fig. 2, these earth connection 5 other ends stretch out from first end cap 3 among the embodiment two, stretch out a pair of conductive pole 41 of serial connection each other simultaneously on second end cap 4.

See also Fig. 3, also be provided with ground terminal 51 on first end cap 3 among the embodiment three, the ground terminal 51 that this earth connection link covers, thus the electric weight of radiator is drawn.

See also Fig. 4, these earth connection 5 other ends can also stretch out from second end cap 4 among the embodiment four.

The above is merely the preferred embodiment of the utility model, and the protection domain of the utility model is not limited thereto, and anyly all belongs within the utility model protection domain based on the equivalent transformation on the utility model technical scheme.
