Similarly, the phrase "if it is determined" or "if [described condition or event] is detected" can be interpreted as meaning "uponce it is determined" or "in response to determining" or "uponce [described condition or event] is detected" or "in response to detecting [described condition or event]", depending on the context.

[0037] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0038] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0039] In view of the problem that the current solution uses manual addressing when there are a large number of photographic lights, which leads to reduced work efficiency and the user cannot intuitively see the shape of multiple photographic lights after splicing, the embodiment of the present application proposes a lamp, such as Figure 1 As shown, the lamp 10 includes a lamp body 11, a control module 12 and a plurality of wireless transceiver modules 13. The control module 12 is arranged on the lamp body 11. The lamp body 11 includes a plurality of splicing sides (in Figure 1 In one embodiment shown in FIG, four splicing sides and four wireless transceiver modules 13 are shown. A wireless transceiver module 13 is provided on each splicing side, and the control module 12 is electrically connected to the plurality of wireless transceiver modules 13 respectively.

[0040] Specifically, the wireless transceiver module 13 is used to send a first wireless signal to an adjacent lamp according to a preset signal, and the first wireless signal is used to characterize the relative position of the adjacent lamp and the lamp 10. The wireless transceiver module 13 is also used to send a first signal to the control module 12 when receiving a second wireless signal sent by an adjacent lamp, and the first signal is used to characterize the position of the lamp 10 and the adjacent lamp. The first wireless signal and the second wireless signal are both infrared light signals, and the first signal is an electrical signal. It should be noted that the preset signal is sent by the control module 12.

[0041] As can be seen from the above, the multiple splicing sides of the lamp 10 can establish wireless communication with adjacent lamps through the wireless transceiver module 13 provided thereon, so that the lamp 10 can determine whether the multiple splicing sides of the lamp 10 correspond to adjacent lamps respectively. Then, after the multiple lamps 10 are spliced, the multiple splicing sides of each lamp 10 can establish wireless communication with adjacent lamps through the wireless transceiver module 13 provided thereon, so that each lamp 10 can determine whether its multiple splicing sides correspond to adjacent lamps respectively. Finally, the relative positions of the multiple lamps 10 can be converted into a linked list of the relative positions between the multiple lamps 10, that is, each lamp 10 can determine the shape of the multiple lamps 10 after splicing according to the above linked list, so that the user can intuitively see the shape of the multiple lamps 10 after splicing, and the address of each lamp 10 corresponds one-to-one to the address of the lamp 10 on the spliced ​​shape, so there is no need for manual addressing, thereby avoiding the problem of reduced work efficiency caused by manual addressing.

[0042] It should be noted that the number of splicing sides on the lamp body 11 can be 2, 3, 4, 5, 6, ..., etc. The user can select the lamp 10 according to the actual situation. The present application does not limit the number of splicing sides of the lamp body 11. When the number of splicing sides is 2 and they are two opposite sides, the lamp body 11 can be infinitely spliced ​​along at least the first direction (i.e., the x direction), see Figure 2 , Figure 2 The bold position in the figure indicates the splicing side of the lamp body 11. When the number of the splicing sides is 4 and they are 4 opposite sides, the lamp body 11 can be infinitely spliced ​​along at least two directions (ie, the x direction and the y direction), see Figure 3 .

[0043] like Figure 4 As shown, the wireless transceiver module 13 includes a transmitting unit 131 and a receiving unit 132 , and the transmitting unit 131 and the receiving unit 132 are electrically connected to the control module 12 respectively.

[0044] Specifically, if an adjacent lamp is provided at one of the splicing sides of the lamp 10, the transmitting unit 131 in the lamp 10 is used to send a first wireless signal to the adjacent lamp according to a preset signal, and the receiving unit in the adjacent lamp sends a second signal to the control module in the adjacent lamp upon receiving the first wireless signal, and the second signal is used to indicate the relative position between the adjacent lamp and the lamp 10, that is, the adjacent lamp is provided at one of the splicing sides. At the same time, the receiving unit 132 in the lamp 10 is used to send a first signal to the control module 12 upon receiving the second wireless signal sent by the adjacent lamp, and the first signal is used to indicate the relative position between the lamp 10 and the adjacent lamp, that is, the adjacent lamp is provided at one of the splicing sides of the lamp 10.

[0045] As can be seen from the above, each spliced ​​side of the lamp 10 can establish wireless communication with an adjacent lamp through the transmitting unit 131 and the receiving unit 132 , so that the lamp 10 can determine whether its spliced ​​side corresponds to an adjacent lamp.

[0046] like Figure 4 As shown, the control module 12 includes a controller 121, and the controller 121 is electrically connected to the plurality of wireless transceiver modules 13.

[0047] Specifically, if an adjacent lamp is provided at one of the splicing sides of the lamp 10, the lamp 10 can establish communication with the adjacent lamp through the wireless transceiver module 13: when the controller 121 in the lamp 10 receives a communication instruction to communicate with the adjacent lamp, the controller 121 modulates the basic carrier signal to generate a preset signal, and sends the preset signal to the transmitting unit 131, and the transmitting unit 131 sends a first wireless signal to the adjacent lamp according to the preset signal. When the receiving unit in the adjacent lamp receives the first wireless signal, it sends a second signal to the controller in the adjacent lamp, and the second signal is used to characterize the relative position of the adjacent lamp and the lamp 10, that is, the lamp 10 is provided at one of the splicing sides of the adjacent lamp. At the same time, the receiving unit 132 in the lamp 10 is used to send a first signal to the controller 121 when receiving the second wireless signal sent by the adjacent lamp, and the controller 121 parses the first signal (that is, parses it according to the corresponding coding rule), and after parsing, the relative position of the lamp 10 and the adjacent lamp can be determined, that is, the adjacent lamp is provided at one of the splicing sides of the lamp 10. The preset signal is a PWM (Pulse Width Modulation) signal. It should be noted that the communication instruction can be input by the user or built-in, and this application does not limit this.

[0048] Exemplarily, the controller 121 is a single chip microcomputer.

[0050] Specifically, if an adjacent lamp is provided at one of the splicing sides of the lamp 10, the lamp 10 can establish communication with the adjacent lamp through the wireless transceiver module 13: when the controller 121 in the lamp 10 receives a communication instruction to communicate with the adjacent lamp, the controller 121 modulates the basic carrier signal to generate a preset signal, and sends the preset signal to the control end of the first switch tube Q1, so that the infrared transmitting tube U1 sends an infrared light signal (i.e., a first wireless signal) to the adjacent lamp according to the preset signal. When the receiving unit in the adjacent lamp receives the first wireless signal, it sends a second signal to the controller in the adjacent lamp, and the second signal is used to characterize the relative position of the adjacent lamp and the lamp 10, that is, a lamp 10 is provided at one of the splicing sides of the adjacent lamp.

[0051] Exemplarily, the first switch tube Q1 is an NPN transistor, the control end of the first switch tube Q1 is the base of the NPN transistor, the first conduction end of the first switch tube Q1 is the collector of the NPN transistor, and the second conduction end of the first switch tube Q1 is the emitter of the NPN transistor.

[0052] Exemplarily, the infrared emitting tube U1 may be an infrared emitting tube with a wavelength of 940 nm, or an infrared emitting tube with a wavelength of 850 nm.

[0053] like Figure 6 As shown, the transmitting unit 131 further includes a first resistor R1, a second resistor R2 and a third resistor R3, wherein the first end of the first resistor R1 is electrically connected to the control end of the first switch tube Q1 and the first end of the second resistor R2 respectively, the second end of the first resistor R1 is electrically connected to the control module 12, the second end of the second resistor R2 is grounded, the first end of the third resistor R3 is electrically connected to the anode of the infrared transmitting tube U1, and the second end of the third resistor R3 is electrically connected to the first power supply. Among them, the first resistor R1 is a current limiting resistor at the control end of the first switch tube Q1, the second resistor R2 is a pull-down resistor at the second conduction end of the first switch tube Q1, and the third resistor R3 is a current limiting resistor of the infrared transmitting tube U1.

[0054] like Figure 7 As shown, the receiving unit 132 includes an infrared receiving tube U2 , the positive electrode of the infrared receiving tube U2 is electrically connected to the first power supply, the negative electrode of the infrared receiving tube U2 is grounded, and the signal output end of the infrared receiving tube U2 is electrically connected to the control module 12 .

[0055] Specifically, the infrared receiving tube U2 in the lamp 10 is used to receive the infrared light signal (i.e., the second wireless signal) sent by the adjacent lamp, convert the infrared light signal into an electrical signal (i.e., the first signal), and send it to the controller 121 through the signal output end of the infrared receiving tube U2. The controller 121 parses the electrical signal (i.e., parses it according to the corresponding coding rules). After the analysis, the relative position of the lamp 10 and the adjacent lamp can be determined, that is, an adjacent lamp is provided on one splicing side of the lamp 10.

[0056] like Figure 8 As shown, the receiving unit 132 further includes a fourth resistor R4, a fifth resistor R5 and a first capacitor C1, the first end of the fourth resistor R4 is electrically connected to the first end of the fifth resistor R5 and the first power supply respectively, the second end of the fourth resistor R4 is electrically connected to the first end of the first capacitor C1 and the positive electrode of the infrared receiving tube U2 respectively, the second end of the first capacitor C1 is grounded, and the first end of the fifth resistor R5 is electrically connected to the signal output end of the infrared receiving tube U2.

The wireless transceiver module in the lamp 10 is also used to send a first signal to the control module in the lamp 10 when receiving a second wireless signal sent by the adjacent lamp, wherein the first signal is used to indicate the relative position of the lamp 10 and the adjacent lamp.

[0059] A plurality of lamps 10 are spliced ​​together to form a lighting system 20. The plurality of spliced ​​sides of each lamp 10 in the lighting system 20 can establish wireless communication with adjacent lamps through the wireless transceiver modules arranged thereon, so that each lamp 10 can determine whether its plurality of spliced ​​sides correspond to adjacent lamps, respectively. Finally, the relative positions of the plurality of lamps 10 can be converted into a linked list of the relative positions between the plurality of lamps 10, that is, each lamp 10 can determine the shape of the plurality of lamps 10 after splicing is completed according to the above linked list, so that the user can intuitively see the shape of the plurality of lamps 10 after splicing, and the address of each lamp 10 corresponds one-to-one to the address of the lamp 10 on the spliced ​​shape, so that manual addressing is no longer required, thereby avoiding the problem of reduced work efficiency caused by manual addressing.

[0060] The present application also provides a lighting control system. Fig.10As shown, the lighting control system 30 includes a control device 31 and the lighting system 20 described above, and the control device 31 communicates with multiple lamps in the lighting system 20 respectively.

[0061] Specifically, each lamp in the lighting system 20 can send a linked list of relative positions between multiple lamps to the control device 31. The user can use the control device 31 to arrange the lighting effects of each lamp (for example, multiple lamps flash in sequence at fixed intervals) to meet the user's requirements for brightness and lighting effects.
