Rather, these embodiments are provided to enable the present disclosure to be understood more thoroughly and to fully convey the scope of the present disclosure to those skilled in the art. 
     Examples of the present disclosure provide an assembled lamp. With reference to  FIG. 1  and  FIG. 2A , the assembled lamp  10  includes at least two lamps ( FIG. 1  shows six lamps, i.e., a lamps  11  to a lamps  16 ) sequentially connected, wherein each lamp has a plurality of side walls  20 , a first conductive terminal  21  is arranged on at least one of the plurality of side walls  20 , a row hole  31  corresponding to the first conductive terminal  21  is disposed on other side wall  20 , and a second conductive terminal (not shown) is arranged in the row hole  31 . 
     With reference to  FIG. 1  to  FIG. 2B , a power supply bus, a processor  41  and a light source device  42  which are connected with the power supply bus, and a communication bus connected with the processor  41  are also arranged inside the lamp, and both the power supply bus and the communication bus are connected with the first conductive terminal  21  and the second conductive terminal of the lamp, wherein there are two power supply buses, one power supply bus is used as a positive end, the other power supply bus is used as a negative end, in  FIG. 2B , one line represents two positive and negative power supply buses, the power supply bus is connected with a power supply terminal in the first conductive terminal  21 , and each terminal in the first conductive terminal  21  will be illustrated in detail hereafter, wherein the processor  41  may be a single chip microcomputer and also may be a circuit set up by a digital analog device, and the circuit has functions of receiving a signal, sending the signal and controlling a load. 
     In the assembled lamp  10 , according to the examples of the present disclosure, two adjacent lamps respectively are a first lamp (e.g., the lamp  11  in  FIG. 1 ) and a second lamp (e.g., the lamp  12  in  FIG. 1 ), wherein the first conductive terminal  21  of the lamp  11  is inserted into the row hole  31  of the lamp  12  and connected with the second conductive terminal in the row hole  31 , so that electrical connection and communication connection between two adjacent lamps can be implemented. In addition, in order to increase maintaining strength of connection between the first conductive terminal  21  and the second conductive terminal, magnet members (which are not shown in the drawings) also may be arranged on the first conductive terminal  21  and the second conductive terminal, or the first conductive terminal  21  and the second conductive terminal are set to be magnetic itself, so that after the first conductive terminal  21  of the first lamp is inserted into the row hole  31  of the second lamp with the second conductive terminal, the first conductive terminal  21  and the second conductive terminal absorb through the respective magnet members or absorb mutually because of being magnetic itself, thereby implementing mechanical connection between two adjacent lamps. 
     The power supply bus of the lamp  11  is used for receiving an external voltage signal, in one aspect, supplies power to the processor  41  and the light source device  42  inside, and in the other aspect, transmits the external voltage signal to the power supply bus of the lamp  12  via the conductive terminal in inserted connection therewith, so that the lamp  12  utilizes the received voltage signal to supply power to the processor  41  and the light source device  42  thereof, wherein the external voltage signal received by the power supply bus may be a voltage signal from an external power supply. 
     The communication bus of the lamp  11  receives a control signal from an external main controller (which is not shown in  FIG. 1  to  FIG. 2B ), the lamp  11  transmits the control signal onto the communication bus of the lamp  12  through the conductive terminal in inserted connection with the lamp  11 , and then the lamp  11  and the lamp  12  determines whether to transmit the control signal on the communication buses into the processors  41 . In one example of the present disclosure, the external main controller may carry preset address information of any one of the lamps in the control signal, so that the lamp determines whether to adopt the control signal to control the light source device  42  of the lamp in a mode of matching the address information. For example, address information of the lamp  11  is carried in the control signal, so that after the control signal is transmitted onto the communication bus, each lamp matches the address information in the control signal with address information of the lamp itself, finally, only the lamp  11  succeeds in matching, the lamp  11  transmits the control signal into the processor  41  of the lamp  11 , and the processor  41  controls a light-emitting state of the light source device  42  inside the lamp by utilizing the control signal. 
     With reference to  FIG. 3  and  FIG. 4 , the first conductive terminal  21  on the side wall  20  of the lamp is arranged along a vertical direction of the side wall  20 , the first conductive terminal  21  of the lamp  11  is in inserted connection to the row hole  31  of the lamp  12 , and after the first conductive terminal  21  is connected with the second conductive terminal (which is not shown in  FIG. 3  and  FIG. 4 ) in the row hole  31 , the side walls  20  where the first conductive terminal  21  and the row hole  31  are respectively positioned are attached to each other.  FIG. 5  shows a structural schematic diagram after two lamps are in inserted connection. 
     In one example of the present disclosure, with reference to  FIG. 2A  and  FIG. 5 , the lamp includes four side walls  20 , the first conductive terminal  21  is arranged on one side wall  20 , the row holes  31  and the second conductive terminals positioned in the row holes  31  are arranged on the other three side walls  20 .

In addition, the lamp also may have other numbers of side walls  20 , such as three or five side walls and the like, and the examples of the present disclosure do not make any limit to it. In the example, a top surface  51  and a bottom surface  52  are respectively disposed at both ends of the side wall  20  of the lamp. The top surface  51  includes a light homogenization plate, light emitted by the light source device  42  (as shown in  FIG. 2B ) inside the lamp uniformly emerges through the light homogenization plate, and the light homogenization plate may be made of a Polycarbonate (PC) material and also may be made of other materials such as glass and the like. The bottom surface  52  is provided with a plurality of convex ribs  53  for reinforcing the bottom surface  52  of the lamp. 
     In the examples of the present disclosure, a capacitance sensor (not shown) also may be arranged on the light homogenization plate, and is connected with the light source device for emitting light inside the lamp, so that a user touches the surface of the light homogenization plate, the light homogenization plate is lighted up by sensing a capacitance of a human body. Specifically, when the user touches the light homogenization plate with a hand, the capacitance sensor on the light homogenization plate senses the capacitance of the hand of the user, so that the light source device may be controlled to emit light. Certainly, it also may be set as that when the user touches the light homogenization plate for the first time, the light source device emits light, and when the user touches the light homogenization plate again, the light source device is turned off, i.e., the light source device does not emit light. 
     With further reference to  FIG. 3  and  FIG. 4 , a guide member  22  is also arranged on the side wall  20  where the first conductive terminal  21  of the lamp is positioned, and a guide groove  32  corresponding to the guide member  22  is also disposed on the side wall  20  where the row hole  31  is disposed. The guide member  22  shown in  FIG. 3  is of a columnar structure, i.e., is a guide column, and correspondingly, the guide groove  32  shown in  FIG. 4  is of a hole shape. In two adjacent lamps, the guide member  22  of the first lamp is in inserted connection into the guide groove  32  of the second lamp, and an opening diameter of the guide groove  32  is smaller than a groove internal diameter, wherein the guide member  22  and the guide groove  32  are used for ensuring that the first conductive terminal  21  and the second conductive terminal can be accurately positioned when being in inserted connection. 
     In the examples of the present disclosure, a stop wall  23  is also arranged on a side of the first conductive terminal  21  of the lamp, a side of the stop wall  23 , which faces away the first conductive terminal  21 , and a bottom surface of the lamp are positioned on the same plane, both ends of the stop wall  23  extend in a direction which is perpendicular to the stop wall  23  and towards the first conductive terminal  21  to form convex edges  24 , and the guide member  22  of the lamp is arranged on a top of the convex edge  24 . Correspondingly, a groove  33  corresponding to the stop wall  23  is disposed on a side of the row hole  31  of the lamp, a depth of the groove  33  is equal to a thickness of the stop wall  23 , and the side wall of the groove  33  is recessed along a reverse direction of an opening of the groove to form the guide groove  32  of the lamp, wherein the design of the stop wall  23  may be used for protecting the exposed first conductive terminal  21  from being bent by an external force. 
     In two adjacent lamps, such as the adjacent lamp  11  and lamp  12  in  FIG. 1 , after the guide member  22  of the lamp  11  is in inserted connection to the guide groove  32  of the lamp  12 , the stop wall  23  of the lamp  11  is in inserted connection into the groove  33  of the lamp  12 , and due to a case that the depth of the groove  33  is equal to the thickness of the stop wall  23 , the bottom surface of the lamp  11  and the bottom surface of the lamp  12  are positioned on the same plane. 
     With further reference to  FIG. 2B  to  FIG. 4 , in one example of the present disclosure, both the first conductive terminal  21  and the second conductive terminal include at least two terminals, wherein the at least two terminals include a positive end and a negative end and the positive end and the negative end are respectively and correspondingly connected with a positive end and a negative end of the power supply bus inside the lamp. Moreover, a terminal at the positive end is also connected with the communication bus inside the lamp and connected with the processor  41  of the lamp via the communication bus. After two adjacent lamps are in inserted connection through the first conductive terminal  21  and the row hole  31 , the first conductive terminal  21  is connected with a terminal with a corresponding function in the second conductive terminal in the row hole  31 , i.e., the positive end terminals and the negative end terminals of the two adjacent lamps, which are connected with the respective power supply buses, are respectively and correspondingly connected, and the terminals connected with the respective communication buses are correspondingly connected. 
     In the examples shown in  FIG. 3  and  FIG. 4 , both the first conductive terminal  31  and the second conductive terminal include four terminals, and the four terminals include two power supply terminals, one communication terminal and one identification terminal, wherein two power supply terminals include a positive end and a negative end, and the positive end and the negative end are correspondingly connected with the positive end and the negative end of the power supply bus inside the lamp; one communication terminal is connected with the communication bus inside the lamp and connected with the processor  41  (as shown in  FIG. 2B ) of the lamp via the communication bus; and the other one is the identification terminal, the identification terminal is used for identifying the lamp connected therewith, the main controller configures the address information to the lamp connected with the identification terminal by the identification terminal for identifying the lamp. In one example of the present disclosure, an Input Output (IO) interface is also arranged inside each side wall of the lamp where the conductive terminal is arranged, and the identification terminal is connected with the IO interface on the side wall where the identification terminal is positioned, so that the IO interface may be identified by the identification terminal, and then the address information may be configured to the lamp connected with the IO interface subsequently, and how to configure the address information to the lamp connected with each IO interface will be specifically illustrated hereafter. 
     In one example of the present disclosure, signal communication between the external main controller and the assembled lamp also may be implemented in a mode of multiplexing a power line (i.e., the power supply bus), i.e., there is no need for the special communication bus to transmit the control signal, but transmission of the control signal is implemented in a mode of superposing the control signal on the power supply bus. 
     At the moment, the conductive terminal may include two power supply terminals, i.e., one positive end terminal and one negative end terminal, and the positive end terminal and the negative end terminal are respectively and correspondingly connected with the positive end and the negative end of the power supply bus inside the lamp. Certainly, the conductive terminal may include three power supply terminals, i.e., two power supply terminals and one identification terminal, moreover, the power supply bus inside the lamp is connected to the power supply terminals, and other portions in the lamp are not changed. 
     In the examples of the present disclosure, when the control signal is transmitted by adopting the communication bus, the control signal may be a digital signal, and when the control signal is transmitted through the power supply bus, the control signal may be an analog signal, i.e., an analog signal with pulses one by one. Certainly, the control signal also may be other forms of signals, and the examples of the present disclosure do not make any limit to it. Moreover, when the external main controller transmits the control signal to the assembled lamp, the control signal is transmitted by a customized transmission protocol, wherein a type of the transmission protocol may be a DMX512 (i.e., DMX Control 512) protocol, a Time To Live (TTL) protocol, a Modbus communication protocol, an IEC101 protocol, an IEC104 (i.e., Telecontrol equipment and systems-Part 5-104) protocol and the like. 
     With further reference to  FIG. 2B , in one example of the present disclosure, the lamp internally further includes a voltage reduction module  43 , one end of the voltage reduction module  43  is connected with the power supply bus, the other end of the voltage reduction module  43  is connected with the processor  41 , and the voltage reduction module  43  receives the external voltage signal through the power supply bus and transmits the external voltage signal to the processor  41  after stabilizing the external voltage signal to a preset voltage value so as to provide a working voltage for the processor  41 . For example, the preset voltage value is 3.3V, i.e., the voltage reduction module  43  provides the external voltage signal to the processor  41  after stabilizing the external voltage signal to 3.3V. Certainly, the preset voltage value also may be other values, and needs to be determined according to the working voltage of the processor  41 . In the practical application, the voltage reduction module  43  may adopt a voltage converter, and the examples of the present disclosure do not make any limit to it. 
     In this example, the lamp internally further includes a drive module  44 , the drive module  44  is respectively connected with the processor  41  and the light source device  42  (for example, a Light-Emitting Diode (LED)) inside the lamp, after receiving the control signal by utilizing the communication bus and processing the control signal, the processor  41  transmits the processed control signal to the drive module  44 , and the drive module  44  generates a corresponding drive signal according to the processed control signal and drives the light source device  42  to emit light or be turned off by utilizing the drive signal. 
     In the example, the control signal may include a signal for controlling the random lamp to emit light or be turned off, and also may include a signal for carrying out dimming control and/or color modulation control on the random lamp. 
     Specifically, the control signal may control one, multiple or all lamps of the assembled lamp to emit light or be turned off (i.e., not to emit light). Certainly, according to the examples of the present disclosure, brightness and a color temperature of the lamp also may be controlled by the external main controller through sending the control signal, and for example, the processor  41  inside the lamp may generate a corresponding Pulse Width Modulation (PWM) signal according to the control signal after receiving the control signal and processing the control signal so as to transmit the PWM signal to the drive module  44 , and the drive module  44  generates the corresponding drive signal according to the PWM signal so as to regulate a color and/or the brightness of the light source device  42 . The light source device  42  may adopt a Red Green Blue (RGB) chip, and the PWM signal implements regulation on the color of the light source device  42 , i.e., implements regulation on the color of the lamp, by regulating respective occupied percentages of red (R), green (G) and blue (B) in the RGB chip. Certainly, the light source device  42  also may adopt a plurality of LEDs with different colors, and regulation on the color of the lamp is implemented by regulating on-off of each color of LED. Regulation on the brightness of the lamp is also implemented by the PWM signal with a corresponding duty ratio, which is generated according to the control signal. 
     Based on the same inventive concept, examples of the present disclosure further provide a lighting system. In connection with  FIG. 3  and  FIG. 4  and with reference to  FIG. 6A  to  FIG. 6C , the lighting system includes a main controller  100  and the assembled lamp  10  (as shown in  FIG. 1 ) in any one of the examples above, and the assembled lamp  10  is connected with the main controller  100 .

     The first conductive terminal  201  of the main controller  100  is inserted into the row hole  31  of any one lamp and connected with the second conductive terminal in the row hole  301 . Or, the first conductive terminal  21  of any one lamp is inserted into the row hole  301  of the main controller  100  and connected with the second conductive terminal in the row hole  301 , so as to implement electrical connection and communication connection between the main controller  100  and the assembled lamp  10 .

It can be known from the examples above, mechanical connection also may be implemented between the lamps in the assembled lamp through the conductive terminals, so that mechanical connection between the main controller and the assembled lamp is implemented. 
     The power supply bus of the main controller  100  receives an external voltage signal (the external voltage signal may be a voltage signal from an external power supply), supplies power to the control module inside, transmits the external voltage signal to a power supply bus of each lamp in the assembled lamp  10  via the conductive terminals in inserted connection therewith, and supplies power to the processor  41  (with reference to  FIG. 2B ) and the light source device  42  (with reference to  FIG. 2B ) inside each lamp.

     In one example of the present disclosure, the first conductive terminal  201  or the second conductive terminal of the main controller  100  includes at least two terminals, and correspondingly, both the first conductive terminal  21  and the second conductive terminal of the lamp include at least two terminals, wherein at least two terminals in the conductive terminals of the lamp include two power supply terminals, the two power supply terminals are respectively used as a positive end terminal and a negative end terminal, the positive end terminal and the negative end terminal are correspondingly connected with a positive end and a negative end of the power supply bus inside the lamp, and the positive end terminal is connected with the communication bus inside the lamp and connected with the processor of the lamp via the communication bus. At least two terminals in the conductive terminals of the main controller  100  include two power supply terminals, i.e., a positive end and a negative end, and the positive end and the negative end are correspondingly connected with a positive end and a negative end of the power supply bus inside the main controller  100 . A terminal at the positive end is connected with the control module of the main controller  100 . After the main controller  100  is connected with the assembled lamp through the conductive terminals, the terminals with the corresponding functions are connected. 
     For example, the main controller  100  is provided with four conductive terminals, wherein two terminals are power supply terminals and are respectively used as a positive end terminal and a negative end terminal, and the positive end terminal and the negative end terminal are correspondingly connected with the positive end and the negative end of the power supply bus inside the main controller  100 . One communication terminal and one identification terminal are respectively connected with the control module of the main controller  100 . The identification terminal of the main controller  100  identifies the lamp connected with each identification terminal in the assembled lamp. Correspondingly, both the first conductive terminal  21  and the second conductive terminal of the lamp include four terminals, wherein in the conductive terminals of the lamp, two terminals are respectively used as a positive end and a negative end, and the positive end and the negative end are correspondingly connected with a positive end and a negative end of the power supply bus inside the lamp. One communication terminal is connected with the communication bus inside the lamp and connected with the processor of the lamp via the communication bus. One identification terminal is used for identifying the lamp connected therewith, and the main controller identifies other lamps connected with the lamp by the identification terminal identifying the lamp, so as to subsequently configure address information to the connected lamp. 
     In the examples of the present disclosure, if the assembled lamp includes at least two lamps sequentially connected, the main controller may be physically connected with any one lamp in the assembled lamp through the conductive terminals, so as to implement connection between the main controller and the assembled lamp. As illustrated in the examples above, both the main controller and the lamp are provided with two power supply terminals, one communication terminal and one identification terminal, the identification terminal of the main controller is connected with the control module thereof, the identification terminal of the lamp is connected with an IO interface on the side wall of the lamp, and actually, it can be understood that the power supply buses inside the lamps are connected and the communication buses in the lamps are connected. Moreover, the power supply bus inside the main controller is connected with the power supply bus of the lamp, the control module of the main controller is connected with the communication bus of the lamp, and the main controller is connected with the IO interface of each lamp. Further, it can be understood that the connected communication buses connect the control module of the main controller with the processor of each lamp, so that communication between the main controller and the random lamp can be implemented, and moreover, the connected power supply buses can provide the required working voltages to the main controller and each lamp. 
     By taking the lighting system as shown in  FIG. 8  as an example, the process that the main controller in the lighting system identifies the IO interface of each lamp by the identification terminal and configures the address information to the lamp connected with the IO interface will be illustrated below. Where, A, B, C, D and E respectively represent the lamps, and numbers 0, 1, 2 and 3 respectively represent numbers of the IO interfaces of the lamps. 
     Step 1: the main controller identifies a lamp A (i.e., a lamp A) physically connected with the main controller by the identification terminal, sets the lamp A as a central node, and configures coordinate values of the lamp A as (128, 128), i.e., both an x-axis coordinate value and a y-axis coordinate value are 128. Meanwhile, the number of the IO interface of the lamp A, which is connected with the main controller, is set as 0, and the numbers of other IO interfaces respectively are 1, 2 and 3 in a clockwise direction. Moreover, the IO interfaces of other lamps are also numbered according to such rule. Certainly, the IO interfaces also may be numbered according to other rules, but the numbering rule of the IO interfaces of each lamp should be the same. The sequence of the numbers of the IO interfaces also may be used as a sequence of configuring the address information to the lamps. 
     Step 2: the control module of the main controller detects a connection case of each IO interface on the lamp A by using the identification terminal and determines that the interfaces 1, 2 and 3 are all connected to a next stage of lamps. 
     Step 3: the main controller respectively configures different coordinate values (i.e., unique address information) to the next stage of lamps B, C and D (i.e., lamps B, C and D) connected with the lamp A according to a preset algorithm strategy on the basis of the coordinate values of the lamp A and coordinate axis directions of the IO interfaces on three interfaces. Therefore, coordinate values of the lamp B are (127, 128), coordinate values of the lamp C are (129, 128), and coordinate values of the lamp D are (128, 129). Moreover, the main controller respectively sets numbers as shown in  FIG. 5  for each IO interface of the lamps B, C and D. 
     Step 4: the control module of the main controller moves a current detection node to a next node, i.e., the lamp B, detects a connection case of each IO interface on the lamp B by the identification terminal on the lamp B, and in the example, determines that the No. 1 IO interface of the lamp B is connected with a lamp E. Further, similarly, on the basis of the coordinate values of the lamp B and coordinate axis directions of the IO interfaces on three interfaces, coordinate values (127, 127) are set for the lamp E in the mode in the above step 3. 
     Step 5: the main controller moves a current detection node to a next node, i.e., the lamp E, detects a connection case of each IO interface on the lamp E, and does not detect out connection of the next stage of lamp. 
     Step 6: the main controller moves a current detection node to a next node, i.e., the lamp C, detects a connection case of each IO interface on the lamp C, and does not detect out connection of the next stage of lamp. 
     Step 7, the main controller moves a current detection node to a next node, i.e., the lamp D, detects a connection case of each IO interface on the lamp D, and does not detect out connection of the next stage of lamp. So far, the main controller completes configuration of the coordinate values to each lamp of the assembled lamp, i.e., completes configuration of the address information to each lamp. 
     The preset algorithm strategy in the step 3 above may be a strategy as follows. 
     Specifically, firstly, establishing a coordinate system for the assembled lamp, and according to the established coordinate system, configuring coordinate values of a central node. For example, a rectangular coordinate system is established for the assembled lamp, and in the rectangular coordinate system, the coordinate values configured to the central node are (128, 128). 
     Then, marking each lamp in the assembled lamp as one node, using the central node as a previous stage of node, acquiring the IO interface of the previous stage of node which is connected with a next stage of node, and determining a coordinate axis direction of the IO interface, wherein each lamp is marked as one node, i.e., each lamp occupies for one coordinate position in the rectangular coordinate system. In this example, the coordinate axis direction means a direction of the IO interface of each lamp on each coordinate axis (for example, an x axis and a y axis) in the coordinate system with respect to the central node. 
     Then, according to the coordinate axis direction of the IO interface of the previous stage of node, which is connected with the next stage of node, determining a node type and a node direction of the next stage of node, and in connection with the coordinate values of the previous stage of node and the node type and the node direction of the next stage of node connected with the previous stage of node, determining coordinate values of the next stage of node, wherein the node type of the examples of the present disclosure may include three types, i.e., the central node, a common node and a turning node. Moreover, the defining principle of each node type is as follows: the lamp physically connected with the main controller is used as the central node, a node of which a longitudinal coordinate is changed with respect to the central node in the rectangular coordinate system is the turning node, and the rest of nodes are the common nodes. For the node direction, the example defines that by using the central node as a base point, a node spliced leftwards is a x-axis negative direction node, a node spliced rightwards is a x-axis positive direction node, a node spliced downwards is a y-axis negative direction node, and a node spliced upwards is a y-axis positive direction node. 
     Finally, continuing to use the node of which the coordinate values are determined latest as a previous stage of node, determining a node type and a node direction of a next stage of node connected with the previous stage of node according to the coordinate axis direction of the IO interface of the previous stage of node, which is connected with the next stage of node, and determining coordinate values of the next stage of node in connection with the latest determined coordinate values, until the coordinate values of the nodes corresponding to all the lamps in the assembled lamp are determined. 
     In one example of the present disclosure, after the main controller completes configuration of the address information to each lamp, a mechanism of host-slave communication protocol may be adopted to control the light-emitting state of the lamp by the main controller, wherein the main controller is used as a host, and the assembled lamp is used as a slave. In each communication process, the host initiates a communication request, and the slave responds to the request of the host. The communication process of the main controller and the lamp will be illustrated below. 
     Specifically, when the control module of the main controller receives a control instruction which is used for controlling the light-emitting state of the assembled lamp and carries at least one piece of address information, at least one piece of address information carried in the control instruction is parsed, the corresponding control signal is generated according to the control instruction, the address information obtained by parsing is carried in the control signal to be sent onto the communication bus, due to connection between each lamp of the assembled lamp and the communication bus, each lamp may match the address information in the control signal on the communication bus with the address information of the lamp itself, if matching is successful, the lamp receives the corresponding control signal by utilizing the communication bus and transmits the control signal into the processor to control the light-emitting state by the processor, so as to implement control on the light-emitting state of the assembled lamp. 
     In one example of the present disclosure, if the main controller is provided with a control panel, information for controlling the light-emitting state of the assembled lamp and the address information of the controlled lamp, which are set by the user through the control panel, may be directly received. If the main controller is not provided with the control panel, but has a communication function of establishing communication connection with an external device (not shown), the control instruction from the external device, which is used for controlling the light-emitting state of the assembled lamp and carries the address information, may be received. The examples of the present disclosure do not make any specific limit to a mode that the main controller receives the control instruction, wherein the external device may be a hand-held device, such as a smartphone in which an Application (APP) capable of communicating with the assembled lamp is installed, and also may be a terminal device and the like. 
     In this example, if the external device adopts the smartphone, and the APP capable of communicating with the assembled lamp is installed in the smartphone, after the main controller completes configuration of the address information (for example, the coordinate values) to each lamp, a schematic image of the assembled lamp also may be formed on an interface of the APP according to a position of each lamp, and the coordinate values of each lamp are labeled on the image, so as to facilitate visually selecting the lamp which needs to be controlled by the user through a display interface of the smartphone. 
     In one example of the present disclosure, if a new lamp is added in the assembled lamp, or the lamp is removed from the assembled lamp, the address information of each lamp in the regulated assembled lamp (i.e., the current assembled lamp) is updated according to an address configuration mode of the examples above, and correspondingly, the schematic image of the assembled lamp in the APP interface is updated.
