Description

Technical Field

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

[0002] A lighting control device 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] The input terminal of a lighting control device is generally connected to a power supply, and the output terminal is generally connected to an LED string. The lighting control device converts the power supply into low-voltage DC through its internal circuitry, and controls the duty cycle of the output signal to achieve different lighting modes for the LED string.

[0004] In most cases, the input terminal of the lighting control device is connected to the power supply. This keeps the lighting control device constantly powered on, meaning some electronic components within the device's internal circuitry are always operational, which can shorten the device's lifespan. To avoid this, a switch is added between the lighting control device and the power supply. This switch controls whether the lighting control device receives power. When the switch is off, the lighting control device loses power, de-energizing its internal circuitry and preventing it from continuously operating.

[0005] The currently used switch includes a housing, a pressing component, a button assembly, a spring, an input connection component, and an output connection component. The housing has mounting holes, and the pressing component mates with these holes to transmit pressing force to the button assembly. The button assembly is located inside and fixed to the housing. One end of the spring mates with the pressing component, and the other end mates with the button assembly. The input connection component is electrically connected to the button assembly, and one end of the output connection component is electrically connected to the button assembly. When pressure is applied to the pressing component, it overcomes the spring's elasticity and acts on the button assembly, causing the button assembly to switch on or off.

[0006] The above structure lacks a sealing structure between the pressing component and the housing, therefore the switch is typically used indoors and cannot be used outdoors or in places where liquids are present. Utility Model Content

[0007] This invention provides a lighting control device that can prevent liquid from entering the housing and causing a short circuit in the switch.

[0008] The technical solutions to the above technical problems are as follows: A lighting control device includes a housing, a pressing component, a button assembly, a spring, an input connection component, and an output connection component. The housing has a first mounting hole. The button assembly is located inside the housing and fixed to the housing. One end of the spring cooperates with the pressing component, the pressing component cooperates with the button assembly, and the other end of the spring cooperates with the housing. The input connection component is electrically connected to the button assembly, and the output connection component is electrically connected to the button assembly. Alternatively, the input connection component is electrically connected to the button assembly through the housing, and the output connection component is electrically connected to the button assembly through the housing. The device also includes at least a portion of an elastic sealing component. The sealing component has a through hole, cooperates with the first mounting hole, is fixed to the pressing component, and also cooperates with the housing.

[0009] In this invention, the sealing component is fixed to the pressing component, and the sealing component cooperates with the outer shell to make the first pressure plate press against the annular boss of the outer shell, and make the other end of the protrusion press against the inner wall surface of the upper shell. In this way, two seals are formed between the second component and the outer shell, thereby preventing liquid from entering the interior of the outer shell, thus avoiding short circuits between the button component and the input connection component and the output connection component.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Example

[0018] like Figures 1 to 6 As shown, the lighting control device of this utility model includes a housing 11, a pressing component 12, a button assembly 13, a spring 14, an input connection component 15, an output connection component 16, and at least a portion of an elastic sealing component. The components and their relationships are described in detail below.

[0019] The outer casing 11 has a first mounting hole 11a. The button assembly 13 is located inside the outer casing 11 and fixed to it. The outer casing 11 includes an upper housing 11c, a lower housing 11d, and a circuit board 11e. After the upper housing 11c and the lower housing 11d are fixed, an assembly cavity 11f is formed between them. The circuit board 11e is located in the assembly cavity and is fixed to the lower housing 11d. The button assembly 13 is electrically connected to and fixed to the circuit board 11e. The button assembly 13 preferably uses a push-button switch. Pressure is applied to the push-button switch to put it in an on or off state.

[0020] The pressing component 12 cooperates with the button assembly 13. There may be a gap between the pressing component 12 and the button assembly 13, or they may be in contact. Pressure can be applied to the pressing component 12 by hand or foot. The pressing component 12 includes a cylinder 12a, a cover plate 12b, and a pressure handle 12d. One end of the cylinder 12a is fixed to the cover plate 12b to close one end of the pressing component 12. A second mounting hole 12c is provided on the circumferential surface of the cylinder 12a for cooperating with a sealing assembly. One end of the handle 12d is fixed to the cover plate 12b, and the other end of the handle 12d is a free end that applies pressure to the button assembly 13. The pressing component 12 also includes an inner cylinder 12e. After the inner cylinder 12e is fixed to the cover plate 12b, an annular cavity 12f is formed between the inner cylinder 12e and the cylinder 12a. The annular cavity 12f is used to cooperate with the spring 14. The inner cylinder 12e is located inside the cylinder 12a and is fixed to the cover plate 12b. The handle 12d passes through the inner cylinder 12e.

[0021] One end of the spring 14 engages with the pressing component 12, and the other end of the spring 14 engages with the outer casing 11. The spring 14 is fitted onto the inner cylinder 12e, and one end of the spring 14 abuts against the cover plate 12b. The spring 14 surrounds the button assembly 13, and the other end of the spring 14 is fixed to the circuit board 11e.

[0022] The input connection component 15 is electrically connected to the button assembly 13, and the output connection component 16 is electrically connected to the button assembly 13. Alternatively, the input connection component 15 is electrically connected to the button assembly 13 via the housing 11, and the output connection component 16 is electrically connected to the button assembly 13 via the housing 11. Since the circuit board 11e has a first conductive line and a second conductive line, the input terminal of the button assembly 13 is electrically connected to the first conductive line on the circuit board 11e, and the output terminal of the button assembly 13 is electrically connected to the second conductive line on the circuit board 11e. Therefore, in this embodiment, it is preferred that the input connection component 15 is electrically connected to the first conductive line on the circuit board 11e, and the output connection component 16 is electrically connected to the second conductive line on the circuit board 11e. The input connection component 15 is used to connect to the power supply, and the output connection component 16 is used to connect to the lighting control device. The button assembly 13 is used to control whether the lighting control device receives power.

[0023] The sealing assembly has a through hole and mates with the first mounting hole 11a. The sealing assembly is fixed to the pressing member 12. The sealing assembly is made of silicone and is fixed to the pressing member 12 by injection molding. The sealing assembly also mates with the outer shell 11. The sealing assembly seals the gap between the pressing member 12 and the outer shell 11, preventing liquid from entering the mounting cavity 11f and thus preventing short circuits caused by liquid between the button assembly 13, the input connection member 15, and the output connection member 16.

[0024] The sealing assembly includes a first component 17, an intermediate connector 18, and a second connecting component 19. The first component 17 mates with the first mounting hole 11a of the sealing assembly and is fixed to the pressing component 12. One end of the intermediate connector 18 is fixed to the first component 17, and the other end of the intermediate connector 18 is fixed to the second connecting component 19. The second connecting component 19 is fixed to the outer shell 11.

[0025] The first component 17 includes a first body 17a in the shape of an annular shape. One end of the first body 17a is provided with an annular groove 17b. A plurality of connecting posts 17c are provided in the annular groove 17b. The connecting posts 17c are fixed to the first body 17a. During injection molding, the other end of the cylinder 12a is engaged with the annular groove 17b. The connecting posts 17c pass through the second assembly hole 12c, thereby fixing the first component 17 and the pressing component 12 into one piece.

[0026] The intermediate connector 18 is a hollow cone, and one end of the intermediate connector 18 is fixed to the outer peripheral surface of the first component 17. When a pressing force is applied to the pressing component 12, the pressing component 12 transmits the force sequentially to the first component 17 and the intermediate connector 18, causing the intermediate connector 18 to deform. Because the intermediate connector 18 has a cone structure, it is not easily damaged after long-term use.

[0027] The second connecting component 19 includes a first pressure plate 19a and a protrusion 19b. The first pressure plate 19a is fixed to the other end of the intermediate connecting body 18. The protrusion 19b protrudes from the axial end face of the first pressure plate 19a. After one end of the protrusion 19b is fixed to the first pressure plate 19a, an annular slot 19c is formed between the protrusion 19b, the first pressure plate 19a and the intermediate connecting body 18. An annular boss 11b is provided on the inner wall surface of the outer shell 11. The annular boss 11b cooperates with the annular slot 19c.

[0028] The sealing assembly also includes a clamping component 20, which includes a pressure ring 20a and a connecting ring 20b. A portion of the sealing assembly is clamped between the pressure ring 20a and the outer shell 11. The connecting ring 20b is fixed to the pressure ring 20a and the outer shell 11. In this embodiment, the pressure ring 20a applies pressure to the first pressure plate 19a, causing the first pressure plate 19a to press against the annular boss 11b, and causing the other end of the protrusion 19b to press against the inner wall surface of the upper shell 11c. This forms two seals between the second connecting component 19a and the outer shell 11, thereby preventing liquid from entering the interior of the outer shell 11. The connecting ring 20b is fixed to the upper shell 11c by welding, preferably by ultrasonic welding. Example

The difference between this embodiment and Embodiment 1 is that a control circuit for changing the lighting mode, timing, dimming, and switching is provided on the circuit board 11e. The structure of the control circuit is prior art and will not be described in detail here.
