Description

Technical Field

[0001] This utility model relates to a lighting controller. Background Technology

[0002] A lighting controller is a device used to control one or more lighting fixtures. It can realize functions such as remote switching, dimming, color temperature adjustment, and fault monitoring, and is widely used in urban lighting, intelligent buildings and other fields.

[0003] Existing lighting controllers typically include a housing, a circuit board, a mode selection component, a pressing component, and an output connection component. The circuit board is located inside the housing and is supported by a support column inside the housing. The mode selection component is electrically connected to the circuit board. The housing has mounting holes, and the pressing component mates with the mounting holes on the housing. The mode selection component mates with the pressing component. The output connection component is electrically connected to the circuit board and is used to connect the lighting fixture.

[0004] When it is necessary to change the lighting mode of the lamp, a pressing force is applied to the pressing component. The pressing component combines with the mode selection component, causing the mode selection component to input a mode selection signal to the control circuit on the circuit board. The control circuit outputs a control command according to the mode selection signal, thereby changing the lighting mode of the lamp. The lighting mode can be to turn on the lamp or turn it off, or to adjust the brightness, color temperature, etc.

[0005] For the aforementioned lighting controller, after the pressing component mates with the mounting holes on the housing, a sealing structure is typically required between the pressing component and the housing, as the controller is used both indoors and outdoors. A common structure involves a slot on the pressing component and a connecting component on the housing that mates with this slot. Once the connecting component is inserted into the slot, a seal is formed. Initially, the seal between the pressing component and the housing is good due to the pressing component's excellent plasticity and other properties. However, after a period of use, the seal gradually fails due to factors such as a decline in the pressing component's performance. Furthermore, since the circuit board is supported by support pillars that only support the edges of the circuit board, the pressing force can easily cause deformation when transmitted to the circuit board. Utility Model Content

[0006] This invention provides a lighting controller that can prevent circuit board deformation during use.

[0007] The technical solutions to the above technical problems are as follows:

[0008] A lighting controller includes a first controller, which comprises a housing, a circuit board, a mode selection component, a pressing component, and a first output connection component. The housing includes a first housing and a second housing connected to the first housing. The circuit board and the mode selection component are both located inside the housing. The circuit board has circuitry. The mode selection component is located at one end of the circuit board and is electrically connected to the circuit board. The second housing has mounting holes. The pressing component engages with the mounting holes on the second housing. The mode selection component engages with the pressing component. The first output connection component is electrically connected to the circuit board. A support assembly is provided inside the first housing. The support assembly engages with the other end of the circuit board and provides support for the circuit board. The position of the mode selection component corresponds to the position of the support assembly.

[0009] In this invention, when a pressing force is transmitted to the circuit board through the mode selection component, the support assembly supports the corresponding part of the circuit board where the mode selection component is mounted, thereby preventing the circuit board from deforming. Because the intermediate connecting part is pressed between the first annular component and the circuit board, deformation of the circuit board is prevented, while simultaneously ensuring a seal between the pressing component and the second housing.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 6 As shown, a lighting controller of this utility model includes a first controller A. The first controller A includes a housing, a circuit board 3, a mode selection component 4, a pressing component 5, a first output connection component 6, and a support assembly. The following is a detailed description of each part and the relationship between them.

[0029] The housing includes a first housing 1 and a second housing 2 connected to the first housing 1. In this embodiment, the second housing 2 and the first housing 1 are arranged in a left-right position (from...). Figure 2 (From the middle view), a support column 1a is installed inside the first housing 1. One end of the support column 1a is fixed to the first housing 1, and the other end of the support column 1a is a free end. The total length of the support column 1a (from Figure 2 (From the middle) and the total length of the supporting components (from Figure 2(Looking at the middle) Equal, the circuit board 3 is supported by the support column 1a and the support assembly.

[0030] Both circuit board 3 and mode selection component 4 are located within the housing. Circuit board 3 has a circuit, and mode selection component 4 is located at one end of circuit board 3 and electrically connected to it. After power-on, the circuit sends a signal to the circuit on circuit board 3 through mode selection component 4, which can change the output signal of the circuit. Since the first output connection component 6 is electrically connected to circuit board 3, and the first output connection component 6 can be connected to, for example, an LED light string, the lighting mode of the LED light string changes accordingly when the output signal of the circuit changes. The circuit on circuit board 3 is prior art, for example, the circuit disclosed in CN105338703B.

[0031] like Figure 2 The mode selection component 4 can be a tactile switch, or the mode selection component 4 can be composed of a conductive button and a carbon film 4a (e.g., Figure 7 The carbon film 4a is mounted on the circuit board 3 and electrically connected to the circuit. The conductive button is set on the pressing component 5. When a pressing force is applied to the pressing component 5, the pressing component 5 drives the conductive button to move towards the carbon film. When the conductive button is combined with the carbon film 4a, the mode selection component 4 sends a signal to the circuit on the circuit board 3. In this embodiment, the mode selection component 4 preferably adopts a tactile switch.

[0032] The second housing 2 has a mounting hole 2d, and the pressing component 5 mates with the mounting hole 2d on the second housing 2. The second housing 2 contains a first annular component 2a and a second annular component 2b, with the second annular component 2b surrounding the first annular component 2a. An annular groove 2c is formed between the second annular component 2b and the first annular component 2a. Multiple limiting posts 2e are provided in the second housing 2. One end of each limiting post 2e is fixed to the second housing 2, and the other end of each limiting post 2e is a free end. The circuit board 3 has multiple notches or insertion holes, and each limiting post 2e mates with one notch or insertion hole. This structure restricts the position of the circuit board 3, preventing displacement of the circuit board 3 within the housing.

[0033] The pressing component 5 is made of silicone or rubber. It includes a cylindrical body 5a, an end cap 5b, an annular wall 5c, and a central connecting portion 5d. The end cap 5b is fixed to one end of the cylindrical body 5a. The end cap 5b has a pressing portion 5e for transmitting force to the mode selection component 4. The annular wall 5c surrounds the cylindrical body 5a. One end of the central connecting portion 5d is fixed to the cylindrical body 5a, and the other end is fixed to the annular wall 5c. An annular slot 5f is formed between the central connecting portion 5d, the cylindrical body 5a, and the annular wall 5c. The first annular component 2a is inserted into the annular slot 5f, and the annular wall 5c is inserted into the annular groove 2c.

[0034] The mode selection component 4 cooperates with the pressing component 5. The pressing part 5e protrudes from the surface of the end cap 5b, and the pressing part 5e is provided with a receiving cavity 5g. The mode selection component 4 is a switch with a pressing handle, and the pressing handle cooperates with the receiving cavity 5g. When the mode selection component 4 is a tactile switch, since the tactile switch itself has a pressing handle, the pressing handle on the tactile switch extends into the receiving cavity 5g and is in clearance fit with the inner wall surface of the pressing part 5e.

[0035] When the mode selection component 4 adopts a structure consisting of a conductive button and a carbon film 4a, such as Figure 7 The conductive button consists of a pressing rod 4b and a conductive film 4c. One end of the pressing rod 4b is fixed to the inner wall surface of the pressing part 5e, and the other end of the pressing rod 4b is a free end. The conductive film 4c is installed on the axial end face of the other end of the pressing rod.

[0036] The cylindrical body 5a includes a first cylindrical body 5a1 and two second cylindrical bodies 5a2. The outer diameter of the second cylindrical bodies 5a2 is smaller than that of the first cylindrical body 5a1. The second cylindrical bodies 5a2 are parallel to the axial direction of the first cylindrical body 5a1 and are connected to the first cylindrical body 5a1. The end cap 5b is provided with three pressing parts 5e, one of which is located on the end face of the first cylindrical body 5a1, and the other two are located on the end faces of the two second cylindrical bodies 5a2 respectively. The pressing parts 5 of this structure are shaped like cartoon characters, such as Mickey Mouse or Kissing Cat. Figure 6 The diagram illustrates that the structure of the pressing component 5 is Mickey Mouse shaped, with the first cylinder 5a1 representing Mickey's face and the two second cylinders 5a2 representing Mickey's ears. Figure 7a and Figure 7b The structure of the pressing part 5 is shown to be in the shape of a kissing cat. This makes the pressing part 5 not only look beautiful and vivid, but also allows the mode selection part 4 to be pressed by pressing the pressing part 5e to change the light emission mode of the LED light string, thereby enhancing the user experience.

[0037] The first housing 1 contains a support assembly, which engages with the other end of the circuit board 3 and provides support for the circuit board 3. The position of the mode selection component 4 corresponds to the position of the support assembly. In this embodiment, the axial direction of the mode selection component 4 is parallel to or on the same straight line as the axial direction of the support assembly. When the first housing 1 and the second housing 2 are fastened together, the intermediate connecting part 5d is pressed between the first annular component 2a and the circuit board 3, thereby ensuring a seal between the pressing component 5 and the second housing 2.

[0038] When the pressing force is transmitted to the circuit board 3 through the mode selection component 4, the support assembly supports the corresponding part of the circuit board 3 where the mode selection component 4 is mounted, thereby preventing the circuit board 3 from deforming. Since the intermediate connecting part 5d is pressed between the first annular component 2a and the circuit board 3, deformation of the circuit board 3 is prevented, and the seal between the pressing component 5 and the second housing 2 is also ensured.

[0039] The support assembly includes a support column 7, one end of which is fixed to the first housing 1, and the other end of which supports the circuit board 3. In this embodiment, the axial direction of the mode selection component 4 is parallel to or on the same straight line as the axial direction of the support column 7. The number of mode selection components 4 is equal to the number of support columns 7. For example, there are three mode selection components 4 and three support columns 7, with each support column 7 corresponding to one mode selection component 4.

[0040] The support assembly also includes a connecting plate 8 and multiple support columns 7. The support assembly is polygonal when two adjacent support columns 7 are connected by the connecting plate 8. The connecting plate 8 can increase the stability and strength of the support columns 7.

[0041] like Figures 8 to 11 This utility model also includes a press controller B for controlling whether the first controller A receives power. The press controller B includes a housing 11, a pressing assembly 12, a button assembly 13, a spring 14, a second input connection component 15, and a second output connection component 16. Pressure can be applied to the press controller B by hand or foot. In this embodiment, the press controller B is particularly suitable for applying pressure by foot, that is, the press controller B is a foot pedal type controller. The press controller B will be described in detail below.

[0042] The outer casing 11 has a mounting hole 11a. The pressing component 12 mates with the mounting hole 11a on the outer casing 11. The pressing component 12 is used to transmit pressing force to the button assembly 13. The outer surface of the pressing component 12 is spherical. A decorative component 11c is provided on the outer casing 11. The decorative component 11c is preferably fixed to the outer casing 11. The decorative component 11c and the pressing component 12 cooperate to form a cartoon shape on the outer casing 11, such as a Mickey Mouse shape or a kissing cat shape. Figure 8 It shows the shape of Mickey Mouse. Figure 12 The illustration depicts the shape of a kissing cat, where the pressing component 12 is Mickey's face and the decorative part 11c is Mickey's ears. This structure not only enhances the aesthetics of the product but also increases the enjoyment of manipulation by applying a pressing force to the pressing component 12.

[0043] The pressing assembly 12 includes a pressure cap 12a and a pressure handle 12b. The pressure cap 12a is clearance-fitted with the mounting hole 11a. The pressure cap 12a is spherical, with an opening at one end and a receiving groove 12c on it. One end of the pressure handle 12b is located in the receiving groove 12c and fixed to the pressure cap 12a. When the pressing assembly 12 is pressed, the other end of the pressure handle 12b is used to transmit the pressing force to the button assembly 13. The pressure cap 12a has a guide groove 12d, and a guide block 11b is provided on the wall of the mounting hole 11a. The guide groove 12d and the guide block 11b are clearance-fitted. The pressure cap 12a has a radial flange 12e on its circumferential surface. The guide groove 12d is formed on the radial flange 12e, which is used to engage with the inner wall of the outer casing 11, thereby preventing the pressure cap 12a from being removed from the outer casing 11.

[0044] The button assembly 13 is located inside the housing 11 and fixed to the housing 11. One end of the spring 14 cooperates with the pressing assembly 12, and the other end of the spring 14 cooperates with the button assembly 13. The second input connection component 15 is electrically connected to the button assembly 13. One end of the second output connection component 16 is electrically connected to the button assembly 13, and the other end of the second output connection component 16 is electrically connected to the circuit board 3.

[0045] The button assembly 13 includes a button switch 13a and a PCB board 13b. The button switch 13a is fixed to and electrically connected to the PCB board 13b. The PCB board 13b is fixed to the housing 11. The second input connection component 15 and the second output connection component 16 are electrically connected to the PCB board 13b, respectively. The PCB board 13b supports the button switch 13a. When the button switch 13a is subjected to a pressing force, compared to a direct fixed connection between the button switch 13a and the housing 11, the force distribution on the button switch 13a is increased, thus ensuring the service life of the button switch 13a. A spring 14 surrounds the button switch 13a, with one end of the spring 14 supported by the PCB board 13b.

[0046] The second input connection component 15 is used to connect a power converter, which converts high-voltage mains power into low voltage, for example, converting 220V high voltage into 12V low voltage. The push-button switch 13a preferably adopts a self-locking button. When the push-button switch 13a is turned on, the low voltage is supplied to the first controller A. When the push-button switch 13a is turned off, the power supply to the first controller A is cut off.
