This arrangement allows the lower housing 14 and the upper housing 15 to be fixedly installed by the plastic screws 13, and at the same time facilitates disassembly when needed to inspect and maintain the internal components.

[0027] Working Principle: When using this device, first fix it in the required position and connect plug 7 to the external power grid. Connect the Y-wire 8 and lamp wire 11 to the corresponding LED eaves light. The power input from plug 7 enters power supply 1 for rectification. Power supply 1 also acts as the primary protector of this electrical box. The power processed by power supply 1 is then protected by protection circuit 5. After that, the power is input to signal controller 2 and exhaust fan 12. The electrical signal input to signal controller 2 is processed by signal controller 2 and then amplified in Mini signal amplifier 3, thereby controlling the operation of Y-wire 8 and lamp wire 11 with the corresponding LED eaves light. The power input to exhaust fan 12 controls the exhaust fan 12 to start, enhancing the air convection effect inside and outside the device, thereby exhausting the hot air inside the device to the outside and improving the heat dissipation effect of the device.
