Abstract
The utility model discloses a kind of replaced type LED lamp tube, including body and drive module, the drive module includes two rectification units, the body is respectively arranged at the two ends with two contact pins, it is connected with the input of one of rectification unit with two contact pins at end, concatenate a switch between every contact pin and the input of rectification unit, the two ends of the switch be parallel with switch resistance, switching capacity or both.The utility model LED lamp tube sets switch between contact pin and the input of rectification unit, forms path and causes to get an electric shock after can avoiding the installation of fluorescent tube one end, the switching overvoltage punch through damage produced when switch resistance can avoid switch from closing is set in addition and is switched.
Description
Technical field
The utility model is related to a kind of fluorescent tube, more particularly to it is a kind of can single both-end enter the replaced type LED lamp tube of electricity.
Background technology
LED lamp tube has the advantages that energy-conservation, luminous flux be high, long service life, just gradually substitutes traditional fluorescent tube.By
In being generally fitted with ballast on the support of conventional fluorescent fluorescent tube, therefore need to bypass ballast by trimming when replacing,
But operation is often complex, and labour intensity is higher.
In order to improve the convenience of replacement, major producers have developed the LED lamp tube that can directly replace, such as
CN203068256U disclose it is a kind of it is direct replace ballast fluorescent tube LED lamp and its device, mainly including ballast, open
Brightness device and LED lamp, the LED lamp include rectification circuit, driving power supply circuit for power conversion and LED illuminator, institute
The one end for stating rectification circuit electrically connects the driving power supply circuit for power conversion, the driving power supply circuit for power conversion it is another
The end electrical connection LED illuminator, described LED lamp is directly installed on the fluorescent tube belonging to the fluorescent tube for being replaced ballast
On support.
By the Fluorescent Light and Fixtures of trimming be typically all it is single-ended enter electricity, and the Fluorescent Light and Fixtures that can carry out direct replacement are
Both-end enters electricity.Whether operating personnel are gone to toward lamp bracket trimming is checked in replacement, are made troubles to operation, therefore exploitation
It is applicable to the LED lamp tube that electricity is entered at single, double end.
Enter the LED lamp tube of electricity using both-end, if wherein one end installation, other end operating personnel touch then
Danger Electric shock risk can occur, therefore U.S. UL standards requirement two ends apply 3108V voltages, need to be less than by the electric current of fluorescent tube
25.9mA, fluorescent tube leakage current is less than 7mA.
Utility model content
The utility model provides a kind of replaced type LED lamp tube, can effectively reduce electric shock risk.
A kind of replaced type LED lamp tube, including body and drive module, the drive module include two rectification units, institute
State body and be respectively arranged at the two ends with two contact pins, be connected with the input of one of rectification unit with two contact pins at end, every is inserted
Concatenate a switch between pin and the input of rectification unit, the two ends of the switch be parallel with switch resistance, switching capacity or it
Both.
Because that must simultaneously switch off or close with two switches at end, it is preferred that same two the two of contact pin, the end of connection pipe body
Switch combination constitutes ganged switch.
Preferably, the switch sets the end face of contact pin located at body, when fluorescent tube is installed, due to the pressing of support, and can be with
Automatic closure switch.
Preferably, the switch is self-resetting switch, when fluorescent tube removal from support, can automatically disconnect switch.
Preferably, the drive module also includes filter unit and constant-current control unit.
Preferably, the filter unit includes one-level filter unit and secondary filter unit, further improves filter effect.
The utility model LED lamp tube sets switch between contact pin and the input of rectification unit, can avoid fluorescent tube one end
Path being formed after installation and causing to get an electric shock, switch resistance or switching capacity are set in addition can avoid what is produced during switch closure
Switching overvoltage punch through damage is switched.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model lamp tube end.
Fig. 2 is the structural representation of the utility model LED drive module.
Specific embodiment
As shown in figure 1, a kind of replaced type LED lamp tube, including body 1, body end is provided with end cap 2, and end cap 2 is provided with slotting
Pin 3, has self-resetting switch 4 between two contact pins 3, the lamp tube ends structure is identical, and accompanying drawing illustrate only wherein one end.Self-resetting
Switch 4 is ganged switch, while connecting two contact pins 3.Aluminium base and drive module are provided with body 1, aluminium base is provided with LED
Lamp bead, tubular body can use existing structure.
As shown in Fig. 2 drive module is hf switching power supply, including two rectification units DB1, DB2, one-level filtering
Unit 5, secondary filter unit 6, constant-current control unit 7, wherein one-level filter unit 5 are capacitor filtering, and secondary filter unit 6 is
Inductor filter, is conventional filter circuit, and constant-current control unit 7 uses existing design.
Improvement of the present utility model is the design of input, and fluorescent tube has four inputs L, N, L1, N1 respectively, is represented
Four contact pins, by taking L and N inputs as an example, concatenate switch T1 and guarantor between input L and the first input end of rectification unit DB1
Dangerous silk F, switch ends are parallel with switch resistance R1, R2；Concatenated out between input N and second input of rectification unit DB1
T2 is closed, switch ends are parallel with switch resistance R3, R4.Switch T1 and T2 is combined constitute ganged switch in the present embodiment, i.e.,
Self-resetting switch 4.That is, switch can be separately provided, or hand switch, but which increase the complexity of operation
Property.
Because the utility model LED lamp tube has two rectification units, therefore can realize that both-end enters electricity, naturally it is also possible to
It is single-ended enter electricity, and two ends are equipped with self-resetting switch, after wherein one end is installed in place, can not form logical with the other end
Road, it is to avoid Danger Electric shock risk.Switch resistance is provided with addition, resistance is very big, it is to avoid switch closure moment produces spark.
