Then, two screws are respectively passed through the base 213 and the first and second side plates 214 and 215 to be locked on the first protrusion 313, thereby firmly connecting the first extension housing 31 and the main housing 21. . In addition, the two end covers 23, 33 can be respectively attached to the end faces 212, 312, and also pass through the side plates 214, 215, 315, the base 213, 314 through the plurality of screws to lock on the bumps 231, 331, Therefore, the end caps 23, 33 are fixed to the main casing 21 and the first extension casing 31. It should be noted that although the positions of the bumps 231, 313, and 331 are disclosed for the purpose of illustration in the present embodiment, the position may be located in an adjacent member. For example, the first bump 313 may also be The first end surface 211 is protruded from the main housing 21 and protrudes into the second end surface 311 of the first extension housing 31 during the docking, and is not limited to the one disclosed in the embodiment. In this way, the creation of the strip light source is unitized and each unit light source is modularized and can be connected to each other, so that the length of the strip light 11 M333654 source is larger than the main unit extension unit. . The embodiment is explained. When the length of 2 is used, one or more of the two extension units can be assembled in another hereinafter, and the second preferred embodiment of the novel expandable strip light source is as follows: a main unit 2, a first An extension unit 3, a second extension unit 4 and a power supply line 5. The main unit 2, the first extension unit 3, and the power supply line 5 of the second preferred embodiment are identical to the corresponding portions of the first preferred embodiment except that the first extension unit 3 has no end cover (not shown). . A second extension unit 4 has the same structure as the first extension housing 3 and includes a second extension housing 41, a second extension disposed in the second extension housing 41, a diaphragm, a group 42, and an end Cover 43. The second extension housing 41 has a third end surface 411 that is paired with the end surface 312 of the first extension housing 31 opposite the second end surface 311. The first extension light-emitting module 42 has a circuit board 421 and a plurality of light-emitting elements 422 disposed on the circuit board 421_L and electrically connected to the circuit board 421. In the embodiment, the light-emitting element 422 is a light-emitting diode for visual inspection. The circuit board 421 of the second extension light-emitting module 42 is electrically connected to the circuit board 321 of the first extension light-emitting module 32 by soldering. The second extension housing 41 is also U-shaped and has a base 414, two side plates 415 extending upward from the two side edges of the base 414 extending along the longitudinal direction I, and a protrusion protruding from the inner surface of the base 414 and protruding The second bump 413 of the three end faces 411 is in the embodiment, the base 414 is a plate body. An accommodating groove 416 is defined in the opposite position of the inner surface of the side plate 415, and extends along the long direction I and is located on a line with the corresponding accommodating groove 316 on the side plate 315 of the first extension housing 31. The two side edges of the circuit board 42 ι of the second extension light emitting module 42 are disposed. When assembled, the second protrusion 413 of the second extension housing 41 extends into the end surface 312 of the first extension housing 31, and then can be locked through the base 314 of the first extension housing 31 and the side plate 315 by using a plurality of screws. The first extension housing 41 is fastened to the first extension housing 31. The end cap 43 of the first extension unit 4 is closed to an end surface 412 opposite to the third end surface 411 of the second extension housing 41. The end cap 43 has a projection 々n, and the projection 431 extends into the end surface 412 of the second extension housing 41, and then the projection 431 is locked in the second extension housing 41 through a plurality of screws. In the red, in order to solve the conventional needs of users of different lengths of strip light source, it is necessary to have various types of housings to be matched, resulting in defects in the manufacturer's inventory and inconvenience in preparation. The extended strip light source is modularized by the extension units 3 and 4, so that the extension units 3 and 4 can easily connect adjacent main unit 2 or extension unit 3, and the number of extension units 3 4 can be adjusted. The strip light source can be expanded or reduced in length along the long direction. In this way, the manufacturer can make the extension units 3 and 4 have fewer specifications or even the same, and the inventory cost can be greatly reduced. The above-mentioned ones are only the preferred embodiments of the present invention, and the short-term b is limited to the scope of the present invention, that is, the simple equivalent change made by the novel patent application scope and the new description content. Modifications are still within the scope of this new patent.
