The known case modulated structure that is used for office or sales field, major part all is to adopt the bar shaped fluorescent lamp that illumination is provided, this case modulated structure comprises: rectangular box, be fixed on most daylight lamp holders of casing two mutual respective side and the fluorescent tube that electrically connects by voltage-stablizer and relay etc. and each daylight lamp holder, the two ends of fluorescent tube have the conducting terminal that connects mutually with described daylight lamp holder respectively; Each conducting terminal with fluorescent tube during combination corresponds respectively to daylight lamp holder do embedding connection, to be combined into the case modulated structure with fluorescent tube.

Yet, above-mentioned case modulated structure still has following problems on reality is used, because described case modulated structure utilizes fluorescent tube that illumination is provided, described fluorescent tube not only power consumption and service life short, need constantly eliminate and more renew fluorescent tube, in addition, because some case modulated structure sets in the high mode of frame, so just more increase the degree of difficulty that the user changes fluorescent tube, caused the inconvenience of use.In addition, the insider designs the LED fluorescent tube of various ways and the case modulated structure that uses with the mutual assembly of described LED fluorescent tube at the problems referred to above at present, though these schemes can address the above problem, but certainly will eliminate original power supply circuits, Circuits System and the equipment of upgrading comprehensively, thereby cause huge replacement cost, and make the user hesitate to move forward.

The utility model content

The purpose of this utility model is to provide a kind of LED fluorescent tube structure-improved, continues to use the location that daylight base carries out the LED fluorescent tube, and being able under lower use cost fluorescent tube be substituted is the LED fluorescent tube.

For achieving the above object, the utility model provides a kind of LED fluorescent tube structure-improved, comprise: light-transmitting tube body, light emitting module, a pair of insulated end cover and conductor wire, this light emitting module is placed in this light-transmitting tube body inside, and this light emitting module comprises the substrate that is fixed on this light-transmitting tube body and is laid in two or more LED of this substrate; This covers two ends that should light-transmitting tube body respectively insulated end cover; One end of this conductor wire and this light emitting module electrically connect, and the other end then passes this light-transmitting tube body outside.

As can be seen from the above technical solutions, the utlity model has following effect and advantage: by the nonconducting characteristic of end cap, can under the situation that does not change original circuit, directly replace fluorescent tube, to increase the use field of LED fluorescent tube with the LED fluorescent tube.

The specific embodiment

Relevant detailed description of the present utility model and technology contents, conjunction with figs. is described as follows, however appended accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited.

See also Figure 1 and Figure 2, the utility model provides a kind of LED fluorescent tube structure-improved, and it mainly comprises: light-transmitting tube body 10, light emitting module 20, a pair of insulated end cover 30 and conductor wire 40.This light-transmitting tube body 10 is rounded, is formed with opening 11 respectively at these light-transmitting tube body 10 two ends, offers perforation 12 in addition on the light-transmitting tube body 10 near left side opening 11.Light emitting module 20 is contained in light-transmitting tube body 10 inside, and this light emitting module 20 comprises substrate 21 and most LED 22, the substrate 21 of present embodiment is a circuit board, utilize substrate 21 width own directly to set up the centre that is fixed on light-transmitting

tube body

10,22 of each LED are laid on the surface of substrate 21 with straight column mode, and electrically connect mutually with circuit on the substrate 21; In addition, it is made that substrate 21 also can be the good material of thermal diffusivity, electrically connect with series system between each LED 22, and arrangement is fixed on the substrate 21.Described insulated end cover 30 is made with insulating materials, and it mainly is made of the cylinder 31 with blind end and two projections 32 stretching from cylinder 31 outboard end facing epitaxies, and this cylinder 31 corresponds respectively to described opening 11 and covers.One end of this conductor wire 40 and the substrate of light emitting module 20 21 electrically connect, and then electrically connect with LED 22; The other end then passes from the perforation 12 of light-transmitting tube body 10.

Further, the utility model also comprises packing ring 50, and this packing ring 50 is socketed on the described conductor wire 40 and is positioned in the perforation 12 of light-transmitting tube body 10.

In addition, the utility model also comprises plug 60, and this plug 60 is connected in the end of conductor wire 40 away from described substrate 21.

See also Fig. 3 and shown in Figure 4, LED fluorescent tube of the present utility model can be applicable on the lamp box 8, and this lamp box 8 has rectangular box 81, is connected with tube face 82 respectively on the mutual corresponding sides of casing 81.Top board at casing 81 offers through hole 83 and is fixed with electric power control module 84 in addition, and these electric power control module 84 internal configurations have electric components such as transformer and frequency converter.This electric power control module 84 is with the effect of step-down and frequency modulation, is converted to the output of low-voltage dc circuit in order to the input with the high-voltage alternating circuit, and is provided with socket 841 at a side of electric power control module 84.During use, two insulated end covers 30 are corresponded respectively to tube face 82 do to embed the location,, therefore do not have electrical conduction with tube face 82 because insulated end cover 30 is non-conductive.Secondly, the plug 60 that is connected in conductor wire 40 through hole 83 from casing 81 is passed, and electrically connect corresponding to the socket 841 of electric power control module 84.So, can continue to use equipment such as original casing 81, tube face 82, and can only change, thereby reduce use cost significantly at the fluorescent tube of part.
