As a kind of preferred version, first wall of described containing cavity is provided with the elastic contact blade that is electrically connected with the LED lamp, and corresponding to this elastic contact blade, first end face of power module is provided with the first conduction haptic element of this elastic contact blade of conflicting; Second relative with this first wall in the described containing cavity wall is provided with the pin that is used to be communicated with external power supply, and this pin stretches out outside the positioning seat; And, also be provided with slot on this second wall, aforementioned pin is arranged in this slot, corresponding to this slot, second end face of described power module is provided with the second conduction haptic element, and this second conduction haptic element is inserted to stretch in to form the plug-in structure in this slot and conflict with pin and is connected.

As a kind of preferred version, the monolateral opening of described containing cavity is a radial opening.

As a kind of preferred version, the both sides of described power module are respectively arranged with a grab, and the both sides of positioning seat are respectively arranged with a draw-in groove, and this grab correspondence is installed in this draw-in groove.

The utility model compared with prior art has tangible advantage and beneficial effect, particularly, it mainly is by two positioning seats are set, two positioning seats are fixed in the two ends of body and the containing cavity that corresponding with body respectively end face forms a monolateral opening, two power modules are removably installed in the containing cavity outside the body two ends, then when power module damages, only need the power module that damages is pulled down from containing cavity, the function of use regeneration that an intact power module can be realized the LED fluorescent tube is installed in this containing cavity again.And the replacing of power module is very quick and convenient, extracts the slot of power module from positioning seat that only needs to damage, and the haptic element that then second of intact power module conducted electricity inserts facing to this slot promptly finishes replacing.

For more clearly setting forth architectural feature of the present utility model and effect, the utility model is further described below in conjunction with accompanying drawing and specific embodiment.

The specific embodiment:

Please refer to Fig. 1 to shown in Figure 4, it has demonstrated the concrete structure of the preferred embodiment of the utility model, and present embodiment is that example describes with the T10LED fluorescent tube, a kind of LED fluorescent tube of fast changeable power module, comprise a body 10, two positioning seats 20 and two power modules 30, wherein:

Described body 10 is a cylinder-like structure, and it is built-in with LED lamp (not marking), and the two ends of body 10 are provided with the elastic contact blade 11 that is electrically connected with the LED lamp, in order to be electrically connected with power module 30.

Described two positioning seats 20 are cylindric, and it is fixed in the containing cavity 21 that the two ends of body 10 and corresponding with body 10 respectively end face form a monolateral radial opening, and aforementioned elastic contact blade 11 is positioned on first wall 211 of this containing cavity 21; Second relative with this first wall 211 in the containing cavity 21 wall 212 is provided with the pin 22 that is used to be communicated with external power supply, also is provided with slot 23 on this second wall 212, and this pin 22 is arranged in this slot 23 and stretches out outside the positioning seat 20; And, also be respectively arranged with a draw-in groove 24 in the both sides of positioning seat 20.

Described two power modules 30 are cylinder-like structure, and being used to be communicated with external power supply provides driving electric power for the LED lamp in the body 10; Two power modules 30 are removably installed in the containing cavity 21 outside body 10 two ends, and form the shape that adapts to body 10 with positioning seat 20; Corresponding to aforementioned elastic contact blade 11, first end face 31 of power module 30 is provided with the first conduction haptic element 311 of conflict elastic contact blade 11; Corresponding to aforementioned slot 23, second end face 32 of power module 30 is provided with the second conduction haptic element 321, this second conduction haptic element 321 is inserted to stretch in to form the plug-in structure in this slot 23 and conflict with pin 22 and is connected, the outside of the second conduction haptic element 321 also is provided with guide plate 322 on second end face 32, is used to power module 30 guiding directions are installed; And, corresponding to aforementioned draw-in groove 24, being respectively arranged with a grab 33 in the both sides of power module 30, these grab 33 correspondences are installed in this draw-in groove 24, in order to strengthen the location intensity of power module 30 in containing cavity 21.

During use, owing to do not have power module 30 in the body 10, it is limited to be built in the heat that the LED lamp in the body 10 gives out, and the LED fluorescent tube can have been given play to optimum performance.When power module 30 damages, pull down the containing cavity 21 of power module 30 outside body 10 two ends that only needs to damage, change an intact power module 30 again and get final product.And the replacing of power module 30 is very quick and convenient, extract the slot 23 of power module 30 from positioning seat 20 that only needs to damage, then the second conduction haptic element 321 of intact power module 30 is promptly finished replacing facing to 23 insertions of the slot on the positioning seat 20, thereby realize the function of use regeneration of LED fluorescent tube.
