A kind of LED fluorescent tube
It is the fluorescent tube of light source with LED that the utility model relates to a kind of;
LED has environmental protection, energy-conservation, advantage such as volume is little, reaction is fast, the life-span is long because of it, be regarded as the lighting source of 21 century, therefore progressively replace conventional lamp and be applied in traditional light-emitting device, the LED fluorescent tube promptly is one of them, the scheme that existing LED fluorescent tube usually adopts be with on-chip power in fluorescent tube, when adopting D type radiator, the LED power supply is placed in the D type groove; When adopting the Palta type radiator usually with the end of on-chip power in fluorescent tube; Above-mentioned dual mode all be with on-chip power in fluorescent tube, the operating temperature of power supply is higher, can influence the service life of power supply, and can be several times as much as service life of power supply under the normal condition service life of LED illuminator, when on-chip power, in case power supply breaks down, maintain and replace is very inconvenient.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides the LED fluorescent tube in a kind of lamp holder that the LED driving power is built in fluorescent tube one end, because of driving power separates with the radiator of fluorescent tube, can effectively reduce the operating temperature of power supply, improve the service life of power supply, when driving power breaks down, change easily in addition, make fluorescent tube can continue to use, thereby improved the bulk life time of fluorescent tube.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of LED fluorescent tube, comprise lamp body and two lamp holders that the LED luminous plaque is arranged, the LED driving power is placed in the lamp holder of an end and be connected to form a complete fluorescent tube with lamp body, the input of driving power is connected with two contact pins of lamp holder, and output is connected with the input of LED luminous plaque.
The beneficial effects of the utility model are: significantly improve the bulk life time of power supply and fluorescent tube, simultaneously because of 220V zero line and live wire at an end of fluorescent tube, can thoroughly get rid of the Danger Electric shock risk that causes because of misoperation in the fluorescent tube process is installed.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1: the utility model schematic diagram;
The specific embodiment:
With reference to Fig. 1, the utility model discloses a kind of LED fluorescent tube, include the lamp body 2 and the lamp holder 1 of LED luminous plaque, 3 form, wherein there is the LED luminescent panel lamp body 2 inside, luminescent panel with combine closely as the aluminium section bar of radiator, lamp holder 3 is built-in with LED driving power 4, the input of driving power 4 is connected with two contact pins of lamp holder 3, output is connected with the input of LED luminous plaque, lamp holder 1,3 are plugged on complete fluorescent tube of composition on the lamp body 2, change lamp holder 3 and get final product when driving power breaks down, during use, the zero line of 220V power supply and live wire are connected in the lamp socket of lamp bracket one end, and the contact pin of lamp holder 3 is connected with the lamp socket that is connected to the 220V power supply.
The above only is preferred embodiment of the present invention, can not limit protection scope of the present invention with it, and the present invention also can adopt other structural changes, so long as the equalization of doing according to protection domain of the present invention changes and modify, all should still belong in the scope that the present invention contains.
