In one embodiment, at least one of the first electrical connector 121 and the second electrical connector 131 is a movable connector movably disposed on the module body 100. By arranging at least one of the first electrical connector 121 and the second electrical connector 131 as a movable connector, the processing error and the assembly error of parts can be better adapted, so that an operator can conveniently butt the first electrical connector 121 and the second electrical connector 131 when connecting the first module and the second module, the operator can quickly connect the first module and the second module, and the reliability of electrical connection of the first electrical connector 121 and the second electrical connector 131 can be improved.

Referring to fig. 6, the dotted line in fig. 6 indicates a position before the connector body 132 moves, when an operator connects the first module and the second module, if the first electrical connector 121 and the second electrical connector 131 cannot be mated, the operator can operate the connector body 132 to slide the connector body 132 to a proper mating position in the movable space 136, so that the second electrical connector 131 on the connector body 132 can be precisely mated with the first electrical connector 121, thereby quickly connecting the first module and the second module. The movable connector in this embodiment is simpler in construction and more convenient to operate.

In an alternative embodiment, the connector body 132 is movable in at least the second and third directions. When the operator docks the first electrical connector 121 and the second electrical connector 131, the operator can drive the connector body 132 to move along the second direction and the third direction, so that the connector body 132 can stay at more positions, and therefore the docking position of the second electrical connector 131 can be flexibly adjusted through the structure, so that the operator can dock the first electrical connector 121 and the second electrical connector 131 conveniently, and the operator can rapidly connect the first module and the second module conveniently.

In another alternative embodiment, the side of the connector body 132 facing the mounting seat 133 is provided with an operation notch 134. An operator may place a finger or other tool within the operating notch 134 to adjust the position of the connector body 132 to facilitate mating of the first electrical connector 121 with the second electrical connector 131. The operation notch 134 facilitates the operator to adjust the position of the connector body 132, and also simplifies the structure of the lighting module.

In order to facilitate the quick connection of the first module and the second module by an operator, the module body 100 is further provided with a limiting groove 160, the limiting groove 160 is communicated with the connecting groove 120, and under the condition that the first module is connected with the second module, the extending part 130 of the first module is matched with the limiting groove 160 of the second module, so that the limiting groove 160 can realize the pre-positioning of the first module and the second module, and then the first module and the second module are reliably connected together through parts such as a screw 400, and therefore, the limiting groove 160 can facilitate the quick and reliable connection of the first module and the second module by the operator.

As described above, the limiting groove 160 can realize the pre-positioning of the first module and the second module, so the size of the limiting groove 160 can be set to be relatively large, so that the extending portion 130 can enter the connecting groove 120 more quickly, however, when the size of the limiting groove 160 is large, a large gap will occur between the extending portion 130 of the first module and the connecting groove 120 of the second module, which is not favorable for the reliable connection between the two. Based on this, further, a matching protrusion 125 is disposed in the connecting groove 120, the matching protrusion 125 protrudes relative to the inner wall of the limiting groove 160, and when the first module is connected to the second module, the extending portion 130 of the first module abuts against the matching protrusion 125 of the second module. Alternatively, the fitting protrusion 125 may be integrally provided with the module body 100, or may be connected to the module body 100 by welding, screwing, or the like. The extension portion 130 can be more tightly engaged in the stopper groove 160 by providing the coupling protrusion 125 in the coupling groove 120, so that the first module and the second module can be more reliably coupled.

In a further alternative embodiment, the inner wall of the connecting groove 120 includes a first plane 126, a second plane 127 and a third plane 128 connected in sequence, the first plane 126 and the third plane 128 are opposite, a matching protrusion 125 is provided at the connection position of the first plane 126 and the second plane 127, and/or a matching protrusion 125 is provided at the connection position of the second plane 127 and the third plane 128. Since the inner wall of the coupling groove 120 is formed by a plurality of planes, the coupling groove 120 is easier to mold, and the fitting protrusion 125 is disposed at the joint of the planes, so that the position of the extension portion 130 can be defined by the fitting protrusion 125 in at least two directions, thereby further improving the position-limiting effect of the fitting protrusion 125.

The first plane 126 and the third plane 128 may be perpendicular to the second plane 127, or an end of the first plane 126 away from the second plane 127 and an end of the third plane 128 away from the second plane 127 may be gradually close to each other, but in order to increase the connecting slot 120 appropriately and obtain a larger installation space, an end of the first plane 126 away from the second plane 127 and an end of the third plane 128 away from the second plane 127 may be gradually far away.

In another alternative embodiment, a portion of the fitting protrusion 125 is attached to the inner wall of the connecting groove 120, and another portion is attached to the inner wall of the limiting groove 160. The fitting protrusion 125 can be more firmly disposed by increasing the fitting area, and the fitting area between the fitting protrusion 125 and the extension 130 can be increased, so that the first module and the second module can be more reliably connected.

In one embodiment, the limiting groove 160 is disposed along an inner wall of the connecting groove 120, i.e., a portion of a sidewall of the limiting groove 160 is aligned with a portion of a sidewall of the connecting groove 120. When the module body 100 is processed, the limiting groove 160 and the connecting groove 120 can share the same reference positioning surface, so that the processing precision of the limiting groove 160 and the connecting groove is higher, and the manufacturing precision of the whole lighting module is improved accordingly. Meanwhile, a portion of the sidewalls of the limiting groove 160 and a portion of the sidewalls of the connecting groove 120 may be formed simultaneously through a single operation, so that the structure may also simplify the manufacturing process of the lighting module.

In order to avoid the damage of the first connector or the second connector caused by excessive force when the operator connects the first module and the second module, at least one of the first electrical connector 121 and the second electrical connector 131 may be an elastic connector, the elastic connector includes a base 122 and an elastic member 123, the base 122 is provided with a terminal receiving slot 121a, the elastic member 123 is disposed in the terminal receiving slot 121a, and the conductive terminal 131a contacts with the elastic member 123 when the first module and the second module are connected. On one hand, the elastic member 123 is compressed and deformed, and the deformation allows the elastic member 123 to apply a pressing force to the conductive terminal 131a, so that the first electrical connector 121 and the second electrical connector 131 are more closely fitted, and thus the first electrical connector 121 and the second electrical connector 131 are more reliably electrically conducted; on the other hand, the elastic element 123 can also buffer the force applied when connecting the first module and the second module, so as to avoid the damage to the first electrical connector 121 or the second electrical connector 131 caused by the excessive force applied by the operator.

If moisture or some other impurities enter the connecting groove 120 or the extending portion 130, it may cause damage to components in the connecting groove 120 or the extending portion 130, thereby causing the lighting module to be unable to be powered on for use, therefore, the lighting module further includes a sealing member 170, a sealing matching portion 124 is arranged in the connecting groove 120, the first electrical connector 121 is arranged in the sealing matching portion 124, under the condition that the first module is connected with the second module, the extending portion 130 of the first module can be in sealing matching with the sealing matching portion 124 through the sealing member 170, thereby preventing the moisture or the impurities from entering the connecting groove 120 or the extending portion 130, further protecting the lighting module, and prolonging the service life of the lighting module.

Alternatively, the sealing member 170 may be a sealing ring having a better sealing effect.
