Fig. 2 is stereogram and the sectional view of the lamp holder of a kind of LED fluorescent tube of embodiment mono-of the present utility model.
Detailed description of the invention
For making the technical solution of the utility model clearer, below by specific embodiment, the utility model is elaborated.
Embodiment mono-
With reference to the accompanying drawings, the preferred embodiment one of the structure to a kind of LED fluorescent tube of the present utility model describes.
Below in conjunction with accompanying drawing, the specific embodiment of a kind of LED fluorescent tube that the utility model is provided is described in detail.
As shown in Figure 1, a kind of LED fluorescent tube that the utility model provides comprise a LED light source 1 and two be positioned at LED light source 1 two ends and with the interconnective LED lamp holder 2 of LED light source.
Described LED light source 1 comprises that 12, one of LED lamp holder connecting portions that 11, two, a shell lays respectively at shell 11 two ends are positioned at the LED light source module 13 of described shell 11 inside and in order to connect the heat-conducting glue of LED light source module 13 and shell 11.Described shell 11 can be full PC shell, also can be all-glass casing, in the present embodiment, described shell is all-glass casing, it is shaped as circular cylindrical cavity, two opposite flanks of going up along its length at described shell are respectively provided with LED lamp holder connecting portion 12, for realizing being connected between shell 11 and LED lamp holder 2.Described LED light source module 13 comprises pcb board and is positioned at the LED luminescence unit of described pcb board upper surface.Pcb board upper surface is provided with multiple LED luminescence units, and its lower surface is installed on enclosure and is provided with heat-conducting glue place, by heat-conducting glue, described pcb board is sticked on to the inside of described shell.
As shown in Figure 2, described LED lamp holder 2 is the cup body structure of groove, comprise: at least one is positioned at the radiator structure 21 of described cup body structure bottom, one is arranged at the draw-in groove 22 of described cup body structure side inwall, 23, two of a shell connecting portion that are connected with described LED lamp holder connecting portion runs through the copper pin 24 of described bottom of cup and is positioned at the driving power of lamp holder inside.
Described radiator structure 21 is to be the design of interdigitated electrode structure hollow out in described cup body structure bottom; Preferably, described radiator structure 21 is in cup body structure bottom dense distribution, and its Breadth Maximum should be less than 1mm, and maximum length is less than 3mm; In other embodiments, described radiator structure 21 can be to be also the design of roundlet pass hollow out in described cup body structure bottom.On lamp holder due to LED lamp tube ends, be provided with radiator structure 21, therefore two ends lamp holder can form cross-ventilation, promoted the heat-sinking capability of LED fluorescent tube, on the other hand, because the size of this radiator structure is less, therefore can effectively prevent that mosquito from entering fluorescent tube inside.
