Description
Technical field
The utility model relates to the room lighting technical field, particularly relates to a kind of dual power supply LED fluorescent tube.
Background technology
Mostly traditional fluorescent tube is fluorescent lamp, and respectively there is a filament at the lamp two ends, is filled with argon and the thin mercury vapour of trace in the fluorescent tube, scribbles fluorescent material on the tube inner wall, sends ultraviolet ray during gaseous conduction between two filaments, makes fluorescent material send visible light.Owing to contain heavy metal pollution material " mercury ", make that the fluorescent tube of scrapping is very serious to the pollution of environment, light efficiency is low, power consumption is big, service life is short.
Along with the application popularization of LED lighting source, also having occurred is the bar shaped illuminating lamp tube of light emitting source with LED.Present single-ended powered power supply: two pins of LED lamp tube ends lamp holder are unconnected in inside; The inner driving power that inserts of lamp holder that has only an end; The other end is a hovering; Live wire and zero line must be connected on the end that driving power is arranged of LED fluorescent tube, and normally luminous lighting inserts the other end and can not light.Though this type of drive has been avoided the danger of getting an electric shock, and installs and uses inconvenience.
Summary of the invention
The purpose of the utility model is to avoid weak point of the prior art and long, easy to use dual power supply LED fluorescent tube of a kind of safe, energy-conservation, life-span is provided.
The purpose of the utility model realizes through following technical scheme.
A kind of dual power supply LED fluorescent tube; Comprise that fluorescent tube cover body and led light source assembly, led light source assembly are installed in the inside of fluorescent tube cover body; The two ends of fluorescent tube cover body are equipped with lamp holder, and the inside of lamp holder is equiped with the built-in power device, and two built-in power devices are connected with the led light source electrical component respectively.
Wherein, the led light source assembly comprises LED lamp pearl and pcb board, and LED lamp pearl is installed in pcb board, and two built-in power devices are electrically connected with pcb board respectively.
Wherein, the fluorescent tube cover body is a PC light diffusion shell.
Wherein, also be provided with radiator, radiator and fluorescent tube cover body touch, and the two ends of radiator are connected with the lamp holder at fluorescent tube cover body two ends respectively.
Wherein, lamp holder comprises plastic cover and stitch, and stitch is fixedly connected with plastic cover, and an end of stitch is exposed to plastic cover, and the inside that the other end of stitch is arranged at plastic cover is connected with the built-in power device.
Wherein, PC light diffusion shell is set to hollow cylindrical structure.
The beneficial effect of the utility model: a kind of dual power supply LED fluorescent tube; Comprise that fluorescent tube cover body and led light source assembly, led light source assembly are installed in the inside of fluorescent tube cover body; The two ends of fluorescent tube cover body are equipped with lamp holder; The inside of lamp holder is equiped with the built-in power device, and two built-in power devices are connected with the led light source electrical component respectively.Compared with prior art, the dual power supply LED fluorescent tube of the utility model has characteristics such as safe, energy-conservation, life-span is long and easy to use.

The specific embodiment
In conjunction with following examples the utility model is described further.
A kind of dual power supply LED fluorescent tube; Extremely shown in Figure 3 like Fig. 1; Comprise that fluorescent tube lampshade 1 and led light source assembly, led light source assembly are installed in the inside of fluorescent tube lampshade 1; The two ends of fluorescent tube lampshade 1 are equipped with lamp holder 2, and the inside of lamp holder 2 is equiped with the built-in power device, and two built-in power devices are connected with the led light source electrical component respectively.Because of the built-in power device of led light source assembly with fluorescent tube lampshade 1 two ends all is electrically connected; But the utility model both can also be supplied power at two ends in single-ended power supply, and was easy to use, again because of going into live wire in a termination of dual power supply LED fluorescent tube; The other end is not owing to form the danger that the loop does not then have electric shock with extraneous power supply; The relative traditional fluorescent lamp saving power and preventing pollution of led light source assembly dye and the life-span long, and lamp tube ends all can with the running of joining of extraneous power supply, in time wherein a damaged on end is bad still can work on; Therefore, this structure LED fluorescent tube has characteristics such as safe, energy-conservation, that the life-span is long.
In the present embodiment, the led light source assembly comprises LED lamp pearl and pcb board, and LED lamp pearl is installed in pcb board, and two built-in power devices are electrically connected with pcb board respectively, can make LED lamp pearl luminous after the energising.Wherein, lamp holder 2 comprises plastic cover and stitch 3, and plastic cover stitch 3 is fixedly connected with plastic cover, and an end of stitch 3 is exposed to plastic cover, and the inside that the other end of stitch 3 is arranged at plastic cover is connected with the built-in power device.
Preferred fluorescent tube lampshade 1 is a PC light diffusion shell in the present embodiment, and wherein, PC light diffusion shell is set to hollow cylindrical structure.
Because the illumination of PC light diffusion shell light-permeable, and can LED light evenly be spread, make light even.
Present embodiment further is provided with radiator 4, and radiator 4 touches with fluorescent tube lampshade 1, and the two ends of radiator 4 are connected with the lamp holder 2 at fluorescent tube lampshade 1 two ends respectively.Set up radiator 4 and can the heat that the led light source operation produces in time be left on the one hand and improve LDE lamp pearl luminous efficiency, can play the effect of support luminous tube on the other hand.
The mode of connection of this structure of the utility model has, and a termination of dual power supply LED fluorescent tube is gone into extraneous power supply, live wire only therewith end connect so people's situation about can not get an electric shock when contacting with the other end; In addition, the mode of connection can also be that the two ends of dual power supply LED fluorescent tube all are connected with extraneous power supply, but live wire only is connected with an end wherein, also can not get an electric shock when the people contacts with the other end.
Should be noted that at last; Above embodiment only be used to explain the utility model technical scheme but not to the restriction of the utility model protection domain; Although the utility model has been done detailed description with reference to preferred embodiment; Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model, and do not break away from the essence and the scope of the utility model technical scheme.
