The length of the flexible flat cable 2 and the number of each light source connector 10, 20, 30 are not limited, and the number and length disclosed here are only for the purpose of illustration. In addition, the flexible flat cable 2 between each light source connector 10, 20, 30 can be continuous or separated.

[0063] For reference Figure 2 , is a schematic diagram of the structure of a light source connector according to an embodiment of the present invention. Figure 2 In the embodiment, the flexible flat cable 2 includes a conductor 22. The conductor 22 can transmit a signal (power signal or control signal, etc.) to the light-emitting units 42, 44 to drive the light-emitting units 42, 44. For example, the light-emitting units 42, 44 can be light-emitting diodes (LEDs), cold cathode fluorescent lamps (CCFLs), etc. Furthermore, the flexible flat cable 2 forms an exposed area BA to expose the conductor 2. In this embodiment, the light-emitting units 42, 44 are described by taking two ends as an example. In another embodiment, the light-emitting units 42, 44 can be changed from two ends to one end.

[0066] exist Figure 3a In the embodiment, the cover 12 is combined with the first buckle 14 to cover the connection module 18 therein.

[0067] exist Figure 3b In the embodiment, the connection module 18 is fixed (e.g., welded) to the light-emitting units 42, 44 by a gasket 182. In addition, the connection module 18 includes a substrate 184 and a second electrode 186 in addition to the gasket 182. The second electrode 186 is disposed on the substrate 184. One end 1862 of the second electrode 186 electrically contacts the light-emitting units 42, 44. In addition, a second fastening member 188 is formed on two sides of the connection module 18, and the second fastening member 188 forms an opening 1882. In this embodiment, the shape of the second fastening member 188 is a U-shape, and the U-shaped groove can be used to accommodate a portion of the first fastening member 14 mentioned later. In addition, the gasket 182 extends from the U-shaped groove. In other embodiments, the substrate 184 can also form a gasket 182, so that the substrate 184 can be fixed to the light-emitting units 42, 44. Here, the number of the second fastening member 188 and the second electrode 186 is four as an example. In other embodiments, the aforementioned number may not be limited.

[0068] exist Figure 3cIn the embodiment, the first fastening member 14 is combined with the connecting module 18 to set the exposed area BR of the flexible flat cable 2.

Therefore, the first electrodes 16 are connected to each other to short-circuit the conductors 22. In another embodiment, in addition to achieving the short-circuit effect between the conductors 22 and the conductors 22 through the connection of the first electrode 16, the conductors 22 and the conductors 22 can also be directly short-circuited, for example, by coating any at least two conductors 22 with conductive glue, so that the coated multiple conductors 22 are electrically connected to achieve the short-circuit effect. In even another embodiment, the short-circuit effect can be achieved by bending multiple conductors 22 so that the multiple conductors 22 are in contact with each other.
