Combined lamp and illumination system

An assembled lamp, comprising:

• a first lamp and a second lamp sequentially connected,
• wherein each of the first lamp and the second lamp includes a plurality of side walls, a first conductive terminal is arranged on at least one of the plurality of side walls, a row hole corresponding to the first conductive terminal is disposed on other side wall of the plurality of side walls, and a second conductive terminal is arranged in the row hole;
• wherein each of the first lamp and the second a power supply bus, a light source device and a processor which are connected with the power supply bus, and a communication bus connected with the processor are arranged inside the lamp, and each of the power supply bus and the communication bus is connected with the first conductive terminal and the second conductive terminal of the lamp;
• wherein the first conductive terminal of the first lamp is inserted into the row hole of the second lamp and connected with the second conductive terminal in the row hole so as to implement electrical connection and communication connection between the two adjacent lamps;
• wherein the power supply bus of the first lamp receives an external voltage signal, supplies power to the processor and the light source device inside, and transmits the external voltage signal to the power supply bus of the second lamp via the conductive terminal in inserted connection with the first lamp;
• and the communication bus of the first lamp receives a control signal from an external main controller, and transmits the control signal onto the communication bus of the second lamp via the conductive terminal in inserted connection with the first lamp.
