Description

Technical Field

[0001] This application relates to the field of lighting circuit technology, and in particular to a light source controlled by a gesture microwave induction switch. Background Technology

[0002] Existing light source switch controls are mostly contact-based, which is inconvenient for operators whose hands are not free. Traditional non-contact voice-activated switches are not suitable for most scenarios, especially for quiet home or office environments. Moreover, voice-activated lights cannot be manually turned off without the control of an intelligent system, and the configuration cost of intelligent systems is relatively high. Utility Model Content

[0003] The purpose of this application is to provide a light source with gesture microwave induction switch control that is more widely applicable.

[0004] To achieve the above objectives, this application provides a light source controlled by a gesture-based microwave induction switch: It includes a circuit board, which is electrically connected to a signal transmitter via a power line. The signal transmitter includes a first PCB board, on the surface of which a first microwave transmitter and a second microwave transmitter are disposed. The circuit board is electrically connected to a signal receiver via a signal line. The signal receiver includes a second PCB board, on the surface of which a first microwave receiver and a second microwave receiver are disposed. The first microwave transmitter faces the first microwave receiver, and the second microwave transmitter faces the second microwave receiver. The circuit board is electrically connected to a light source board via a power line, and the light source board is provided with a light-emitting element for converting electrical energy into light energy.

[0005] As a preferred embodiment, the distance between the first microwave transmitter and the second microwave transmitter is equal to the distance between the first microwave receiver and the second microwave receiver, ensuring that the microwave transmitter and the microwave receiver can correspond one-to-one.

[0006] As a preferred option, the distance between the first microwave transmitter and the second microwave transmitter is in the range of 8 to 12 cm, which can better accommodate hand movements.

[0007] As a preferred embodiment, a first positioning hole is provided at the corner of the first PCB board, and a second positioning hole is provided at the corner of the second PCB board, so that the positioning post structure can pass through to achieve installation constraint.

[0008] As a preferred embodiment, the first PCB board is parallel to the second PCB board, making it easier for the microwave transmitter and microwave receiver to be aligned.

[0009] As a preferred embodiment, the light source board includes a mounting base, one surface of which is a reflective surface, and an LED light-emitting unit is disposed within the reflective surface, thus serving both the functions of reflection and preventing overheating.

[0010] As a preferred embodiment, a heat-conducting plate is fixedly connected to the surface of the circuit board, and a threaded hole is provided at the corner of the heat-conducting plate for bolts to pass through to achieve fastening and constraint.

[0011] As a preferred embodiment, a third positioning hole is provided at the corner of the configuration base for engaging with the positioning post inside the lampshade.

[0012] Compared with the prior art, the beneficial effects of this application are as follows: (1) By setting up two sets of microwave transmitters and microwave receivers, the order in which the microwave feedback signal is blocked is used to determine whether the gesture is an opening or closing action, thereby realizing non-contact flexible control without the need for the assistance of an intelligent system, and the cost of use is lower. (2) When the signal transmitter and signal receiver are set inside the door frame, the lights can be turned on automatically when entering the door and turned off automatically when leaving the door. The energy consumption of this control system is relatively low in standby mode, so it can reduce the lighting energy consumption in unattended environments to a certain extent.

[0019] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0021] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0022] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0023] like Figure 1-5 The light source shown is controlled by a gesture microwave induction switch, including a circuit board 5 with a control program internally programmed. A heat-conducting plate 501 is fixedly connected to the surface of the circuit board 5. The heat-conducting plate 501 has a larger surface area, which can accelerate the heat dissipation of the circuit board 5. A threaded hole 502 is provided at the corner of the heat-conducting plate 501, through which bolts are passed to fix the heat-conducting plate 501 together with the circuit board 5 in the power distribution box.

[0024] The circuit board 5 is electrically connected to the signal transmitter 1 via the power cable 3 to supply power to the signal transmitter 1. The signal transmitter 1 includes a first PCB board 101, which also contains circuitry. A first positioning hole 102 is provided at the corner of the first PCB board 101. The first positioning hole 102 avoids the circuitry inside the first PCB board 101 and important components on the PCB, and is used for the positioning post to pass through to achieve positioning and installation. A first microwave transmitter 103 and a second microwave transmitter 104 are provided on the surface of the first PCB board 101 for directional transmission of microwave signals. The distance between the first microwave transmitter 103 and the second microwave transmitter 104 is in the range of 8~12cm, which is slightly larger than the width of a normal human hand and slightly smaller than the length of a normal human hand.

[0025] The circuit board 5 is electrically connected to the signal receiver 2 via the signal line 4 to transmit microwave sensing signals. The signal receiver 2 includes a second PCB board 201, which also contains circuitry. A second positioning hole 202 is provided at the corner of the second PCB board 201. The second positioning hole 202 avoids the circuitry and important components on the PCB board 201, allowing the positioning post to pass through for positioning and installation. A first microwave receiver 203 and a second microwave receiver 204 are provided on the surface of the second PCB board 201 to convert the received microwave signals into electrical signals.

[0026] During installation and configuration, the first PCB board 101 and the second PCB board 201 need to be parallel, and the first microwave transmitter 103 needs to be directly opposite the first microwave receiver 203, and the second microwave transmitter 104 needs to be directly opposite the second microwave receiver 204. Therefore, the distance between the first microwave receiver 203 and the second microwave receiver 204 also needs to be equal to the distance between the first microwave transmitter 103 and the second microwave transmitter 104. The microwave signal emitted by the first microwave transmitter 103 can only be received by the first microwave receiver 203, and the second microwave transmitter 104 can only be received by the second microwave receiver 204. Forming such a one-to-one correspondence is the key to realizing gesture switch control.

[0027] The main circuit board 5 is electrically connected to the light source board 6 via the power supply line 7, which is used to provide stable power to the light source board 6. The light source board 6 is equipped with light-emitting elements. Specifically, the light source board 6 includes a mounting base 601. A third positioning hole 604 is provided at the corner of the mounting base 601 for the positioning post inside the lampshade to pass through to achieve installation constraint. One surface of the mounting base 601 is a reflective surface 602, and an LED light-emitting unit 603 is provided in the reflective surface 602. On the one hand, it is used to reduce the absorption of light by the mounting base 601, thereby delaying the heating. On the other hand, the reflective surface 602 can reflect light to a specific range, thereby improving the light utilization rate.

[0028] Working principle: Signal transmitter 1 and signal receiver 2 need to be set in the passage, such as on both sides of the door frame or corridor. Light source board 6 is set in the position where illumination is needed. The setting position of circuit board 5 is not particularly required. When a human body or hand passes through the first microwave transmitter 103 and the first microwave receiver 203 within a set time, such as 1.25 seconds, and then through the second microwave transmitter 104 and the second microwave receiver 204, the power of the microwave transmitter is relatively low. Moreover, the human body will absorb and emit microwaves, which will significantly block the signal sent from the first microwave transmitter 103 to the first microwave receiver 203. Similarly, it will also block the signal sent from the second microwave transmitter 104 to the second microwave receiver 204. The circuit board 5 detects the change sequence of the feedback signal and will power the light source board 6 to make the LED light-emitting unit 603 light up for illumination, thereby realizing gesture activation. When a human body or arm passes between the second microwave transmitter 104 and the second microwave receiver 204, and then between the first microwave transmitter 103 and the first microwave receiver 203 within the same set time, the feedback signal of the second microwave receiver 204 is blocked first, and the feedback signal of the first microwave receiver 203 is blocked later. The circuit board 5 detects the reverse sequence of feedback signal changes and supplies power to the light source board 6, thus realizing the gesture to turn off the light.
