Description
Technical Field
[0001] The embodiments of the present application relate to, but are not limited to, the technical field of lamps, and in particular, to an LED spot lamp. Background Art
[0002] In the actual use of lamps, due to lighting requirements, multiple lamps are often connected in series. At the same time, with the complication of lighting function requirements, a controller is often required to control multiple lamps simultaneously. At this time, in order to ensure communication between the lamps and the controller, signal lines are usually used to connect the lamps in series. The controller sends the signal line to the first lamp and then realizes the forwarding of the control signal between adjacent lamps through the signal line. However, during the transmission process of the control signal through the signal line, it will be affected by the power line and its own length, resulting in attenuation and interference of the control signal. Therefore, the physical distribution range that a controller can manage is limited. The quality of the control signal beyond this physical distribution range is poor, resulting in the inability to control the lamps. Therefore, in the related art, the physical distribution range of the lamps controlled by the controller is small, and at the same time, the number of lamps controlled is small. Therefore, how to improve the physical distribution range controlled by a single controller so as to increase the number of lamps controlled by a single controller is a technical problem to be solved urgently.

[0025] In order to make the objectives, technical solutions, and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs. The terms used herein are for the purpose of describing embodiments of this application only and are not intended to limit this application.

[0027] In addition, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of the embodiments of the present disclosure. However, those skilled in the art will realize that the technical solutions of the present disclosure can be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. may be used. In other cases, well-known methods, devices, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the present disclosure.
[0028] Referring to Figure 1 and Figure 2 as shown, the LED spotlights proposed according to the embodiments of this application, the LED spotlights include:
[0029] A lighting main body 100, the lighting main body 100 includes a plurality of lamp bodies 120 and a signal buffer module 110, the signal buffer module 110 and the lamp bodies 120 are sequentially spaced apart along a preset signal transmission direction; the signal buffer module 110 and the lamp bodies 120 are connected to each other in pairs; and adjacent two signal buffer modules 110 are connected to each other;
[0030] A controller 200, an output end of the controller 200 is connected to an input end of the first signal buffer module 110 in the signal transmission direction, and the controller 200 is configured to input a control signal to the first signal buffer module 110 so that the control signal sequentially passes through each signal buffer module 110 and each lamp body 120 in the signal transmission direction.
[0031] Therefore, by sequentially spacing apart the signal buffer module 110 and the lamp bodies 120 along the signal transmission direction, and the signal buffer module 110 and the lamp bodies 120 are connected to each other in pairs, and adjacent two signal buffer modules 110 are connected to each other, so that the control signal output by the controller 200 can enter the lamp bodies 120 after being amplified and isolated by the signal buffer module 110, thereby ensuring that each control signal entering the lamp bodies 120 is effective. Therefore, compared with the related art, the embodiments of this application can increase the physical distribution range controlled by one controller 200 and thus increase the number of lamps managed by one controller 200.
[0032] It should be noted that the lamp body 120 is an independent lamp with a lighting function. By sequentially connecting different wires in series, it can respectively achieve power supply to multiple lamp bodies 120 by the same power source and sequential transmission of the same control signal. The functions implemented by the controller 200 in the embodiments of the present application are not limited. The controller 200 can control the brightness, switch, etc. of the lamp body 120.
[0033] It should be noted that the embodiments of the present application do not limit the interval between the lamp bodies 120, and those skilled in the art can selectively set it according to actual needs.
[0034] It should be noted that the signal buffer module 110 is used to amplify and isolate the control signal. Since the control signal is amplified and isolated by the signal buffer module 110 before entering the lamp body 120, the interference and attenuation of the control signal between two adjacent lamp bodies 120 can be reduced. At this time, the range that the controller 200 can control is wider. With the interval between the lamp bodies 120 unchanged, a single controller 200 can achieve unified control of more lamp bodies 120.
[0035] It should be noted that the embodiments of the present application do not limit the mechanical structure of the signal buffer module 110. In some embodiments, the signal buffer module 110 can be encapsulated into a box body, and connection interfaces can be provided on the side wall of the box body to connect the lamp body 120 and the adjacent signal buffer module 110.
[0036] Exemplarily, as Figure 1 shown, there are 3 lamp bodies 120 and 3 signal buffer modules 110 provided in the lighting main body 100. Along the signal transmission direction, the positive power supply wire sequentially connects the signal buffer module 110 and the lamp body 120 in series, and the negative power supply wire sequentially connects the signal buffer module 110 and the lamp body 120 in series, so that both the signal buffer module and the lamp body 120 can be powered by the same power source. Two adjacent signal buffer modules 110 are interconnected through a lamp body 120. The control signal is sequentially transmitted through the interconnected lamp bodies 120 and signal buffer modules 110.
[0037] Exemplarily, as Figure 2 shown, there are n lamp bodies 120 and n signal buffer modules 110 provided. Along the signal transmission direction, the power source is sequentially connected to the power conversion module 300, the controller 200, and the lighting main body 100. The signal buffer modules 110 and the lamp bodies 120 in the lighting main body 100 are arranged alternately.
[0038] It can be understood that with reference to Figure 3As shown, the signal buffer module 110 includes a logic gate chip 111. The input pin of the logic gate chip 111 of the first signal buffer module 110 is connected to the output end of the controller 200, and the input pins and output pins of the logic gate chips 111 of two adjacent signal buffer modules 110 are connected to each other; the output pins of the logic gate chips 111 and the lamp bodies 120 are connected to each other in pairs.
[0039] It should be noted that the logic gate chip 111 is an integrated chip integrated with a logic gate circuit, which can perform operations such as filtering, amplifying, and transforming digital signals.
[0040] It should be noted that by directly using the logic gate chip 111, the volume of the entire signal buffer module 110 can be made smaller, making it more convenient to deploy.
[0041] Exemplarily, as Figure 4 and Figure 5 shown, the logic gate chip 111 is U1.
[0042] It can be understood that, as Figures 3 to 5 shown, the signal buffer module 110 further includes a filter circuit 112. The filter circuit 112 includes a first capacitor and a first resistor. The first capacitor and the first resistor are connected in parallel. The first ends of the first capacitor and the first resistor are both connected to the output pin of the logic gate chip 111 and the first ends of the first capacitor and the first resistor are connected to the adjacent lamp body 120 and the input pin of the logic gate chip 111, and the second ends of the first capacitor and the first resistor are both grounded.
[0043] It should be noted that by adding the filter circuit 112, the output result of the output pin of the logic gate chip 111 can be further filtered to help smooth the output signal and reduce the fluctuations of voltage or current.
[0044] Exemplarily, as Figure 4 and Figure 5 shown, the first capacitor is C4, the first resistor is R6, C4 and R6 are connected in parallel, and the first ends of C4 and R6 are connected to the output pin (i.e., pin 4) of the logic gate chip 111. The signal buffer module 110 further includes a second resistor R5. The first end of the second resistor R5 is connected to C4, R6, and the output pin of the logic gate chip 111, and the second end of R5 serves as the output end of the signal buffer module 110 and is connected to the adjacent lamp body 120 and the adjacent signal buffer module 110.
[0045] It can be understood that, as Figure 3 shown, the signal buffer module 110 further includes a voltage stabilizing circuit 113. The output end of the voltage stabilizing circuit 113 is connected to the power supply pin of the logic gate chip 111, and the input end of the voltage stabilizing circuit 113 is connected to an external power supply.
[0046] It should be noted that by providing the voltage stabilizing circuit 113, the input power supply of the logic gate chip 111 becomes more stable.
[0047] It can be understood that as Figure 4 shown, the voltage stabilizing circuit 113 includes a low dropout linear regulator, a second capacitor, and a third capacitor; the input end of the low dropout linear regulator is connected to an external power supply, the output end of the low dropout linear regulator is connected to the first ends of the second capacitor and the third capacitor, and the first ends of the second capacitor and the third capacitor are connected to the power supply pin of the logic gate chip 111, and the second ends of the second capacitor and the third capacitor are grounded.
[0048] Exemplarily, as Figure 4 shown, the low dropout linear regulator is an LDO; the second capacitor is C2, the third capacitor is C3, and the logic gate chip 111 is U1; the 24V voltage is connected to the first ends of the LDO, C2, and C3 and then connected to the power supply pin (i.e., VCC in the figure) of U1. In some embodiments, as Figure 4 shown, the signal buffer module 110 further includes a third resistor R1. After the current passes through R1 and the LDO, part of it flows into C2 and C3 and then to ground, and part of it flows into the VCC of the logic gate chip 111. In some embodiments, the signal buffer module 110 further includes a sixth capacitor C1. As Figure 4 shown, part of the current flows to C1, and part of the current flows to R1 and the LDO and then part of it flows to C2, C3, and VCC.
[0049] It can be understood that as Figure 5 shown, the voltage stabilizing circuit 113 includes a zener diode, a fourth capacitor, and a fifth capacitor. The first ends of the zener diode, the fourth capacitor, and the fifth capacitor are all connected to the external power supply and the power supply pin of the logic gate chip; the second ends of the zener diode, the fourth capacitor, and the fifth capacitor are connected to each other.
[0050] Exemplarily, as Figure 5 shown, the zener diode is ZD1, the fourth capacitor is C2, and the fifth capacitor is C3. The first ends of ZD1, C2, and C3 are connected to each other, the second ends of ZD1, C2, and C3 are connected to each other, the first end of ZD1 is also connected to the power supply, and the first end of C3 is connected to the VCC of the logic gate chip 111. In some embodiments, the signal buffer module 110 further includes two third resistors R1 and R3 connected in parallel with each other. The second end of the parallel connection of R1 and R3 is connected to the first end of ZD1, and the first end of the parallel connection of R1 and R3 is connected to the power supply.
[0051] It should be noted that as Figure 4 and Figure 5 shown, in some embodiments, another input end of the logic gate chip 111 is also connected to the VCC in series with a fourth resistor R3.
[0052] It is understandable that, with reference to Figure 2 as shown, the LED spot light further includes a power conversion module 300, and the power conversion module 300 is used to supply power to the controller 200, each lamp body 120, and the signal buffer module 110.
[0053] It should be noted that the power conversion module 300 is used to convert the commercial power into the voltage supported by the lamp body 120, such as converting 220V into 24V. The specific structure of the power conversion module 300 is not limited in the embodiments of the present application.
[0054] It is understandable that the logic gate chip 111 is set as SN74LVC1G08.
[0055] Exemplarily, taking the logic gate chip 111 set as SN74LVC1G08 as an example, with reference to Figure 2 as shown, the power conversion module 300 converts the 220V voltage into 24V output and supplies it to n lamp bodies 120 and n signal buffer modules 110. Among them, the controller 200 sends a control signal to the first signal buffer module 110 through a wire, and the first signal buffer module 110 outputs the control signal through SN74LVC1G08 and then gives it to the adjacent lamp body 120. The adjacent lamp body 120 forwards the received control signal to the adjacent signal buffer module 110 through a wire, and so on, to realize the control transmission of the control signals of the n lamp bodies 120. The voltage output by the power conversion module 300 supplies power to each lamp body 120 and the signal buffer module 110 in sequence through a wire, and the signal buffer module 110 provides a 2 - 5.5v power supply to SN74LVC1G08 through the voltage stabilizing circuit 113, so as to ensure the normal operation of SN74LVC1G08. At this time, when the power of the power supply is sufficient, dozens to hundreds of lamp bodies 120 can be connected.
[0056] The above has specifically described the preferred embodiments of the present application, but the present application is not limited to the above - mentioned implementation manners. Those skilled in the art can also make various equivalent deformations or substitutions without departing from the spirit of the present application, and these equivalent deformations or substitutions are all included within the scope defined by the claims of the present application.
