There are no wires outside the housing assembly 10, and there is no need to hide the wires connecting the lamp beads in the building blocks, which does not affect the assembly between the building blocks and does not pose a risk that the wires are easily crushed. Therefore, in the embodiment of the present application, the light can be installed without wiring, which facilitates the installation of the light and increases the convenience.

[0072] Meanwhile, the connecting component 40 in the embodiment of the present application can be rotatably connected to the building block, and the irradiation orientation of the light-emitting component 20 can be adjusted, so that the light of the light-emitting component 20 can irradiate a specific area through the light-transmitting structure, thereby the irradiation area of the light-emitting component 20 can be adjusted.
