The specific embodiment

Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for the utility model is described, but are not used for limiting scope of the present utility model.

Embodiment mono-

As shown in Figure 1, the assembled fixture in the utility model embodiment comprises: pedestal 1, and pedestal 1 comprises loading end 11 and is arranged at the first frame 12 of loading end one end; Loading end 11 is for carrying LGP 3; The first frame 12 is provided with the fixedly draw-in groove 111 of luminescence unit; Be carried on the light in part of the LGP 3 on loading end 11 and be fixed on the exiting surface of luminescence unit in draw-in groove and be fastened togather.

Concrete, this luminescence unit comprises LED lamp 4 and the FPC(Flexible Printed Circuit vertically be connected with LED lamp 4, FPC) 5.In order to be fixed luminescence unit, this draw-in groove 111 is set to T-slot, and this LED lamp 4 sticks in the lateral part of draw-in groove 111, and FPC5 is arranged in the vertical portion of draw-in groove 111.Wherein, LGP 3 light in part are provided with sawtooth, and sawtooth card is combined on the exiting surface of LED lamp 4.

For the light in part by LGP 3 can carry out smooth-going engaging with LED lamp 4 exiting surfaces better, the surface of the bottom of draw-in groove 111 lateral parts a little less than loading end 11 is set, its lower than height and the thickness of LED lamp 4 be complementary, make so draw-in groove 111 surfaces of putting into LED lamp 4 to maintain an equal level mutually with the surface of LGP 3.

In order to make LGP 3 not depart from the loading end 11 of pedestal 1 in the process engaged with LED lamp 4, can with LED lamp 4, effectively engage more accurately, the vertical subregion that is positioned at loading end 11 both sides towards the second frame 13, the second frames 13 of LGP 3 extensions that connects, two ends of frame 12 is set.

It should be noted that, more successfully be placed on loading end for the ease of LGP, the subregion that this second frame 13 is positioned at loading end 11 both sides more preferably is set, certainly, this second frame 13 also can be positioned at the Zone Full of loading end both sides.

For easy to process, the first frame 12 is set and the second frame 13 is wholely set, certainly, but also split setting.

Concrete, the cross section of this second frame 13 is L shaped, and the cross section of described the second frame 13 is L shaped, and the lateral part of described the second frame 13 is connected with LGP 3, and its vertical portion plays restriction LGP 3 and engages the effect of track with LED lamp 4.

Embodiment bis-
