Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of lighting technology, and in particular to a lighting power supply reset circuit and an intelligent lighting fixture. Background Art
[0002] In the field of intelligent lighting in the lighting industry, when wireless intelligent device nodes are connected to the platform, other users cannot discover and use them. If the permissions are lost due to factors such as mobile phone loss, account password forgetting, etc., the quickest way to regain control of the device is to reset the device and restore the factory settings. The most common module reset method is to long press the traditional mechanical button to operate the module reset.
[0003] However, the common practice in the market is to define an IO port on the module and connect it to the button. When the button is long pressed, the reset is started. When designing a product, it is necessary to reserve space for pressing the button. Therefore, in order to press the button, a small hole is added to the structure or a button window is reserved in the structure, which increases the cost; when the user uses it, he needs to directly / indirectly touch the button itself. If the operation is improper, it will cause a certain degree of damage to the product. Utility Model Content

The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0025] The present disclosure relates to a lighting power reset circuit. In one embodiment, the lighting power reset circuit includes a lighting power controller and a magnetic induction conversion circuit; the magnetic induction conversion circuit includes a reset Hall electronic switch tube, a first resistor and a second resistor, the first end of the first resistor is used to connect to a reference power supply, and the second end of the first resistor is connected to the control end of the reset Hall electronic switch tube; the first end of the second resistor is connected to the reference power supply, the second end of the second resistor is connected to the first end of the reset Hall electronic switch tube, the first end of the reset Hall electronic switch tube is also connected to the reset collection end of the lighting power controller, and the second end of the reset Hall electronic switch tube is grounded. When the magnetic field around the reset Hall electronic switch tube decreases, that is, the magnetic object moves away from the reset Hall electronic switch tube, the reset Hall electronic switch tube is in the cut-off state, so that the first end of the reset Hall electronic switch tube maintains a high voltage, thereby causing the reset collection end of the lighting power controller to collect a high level; and when the magnetic field around the reset Hall electronic switch tube increases, that is, the magnetic object approaches the reset Hall electronic switch tube, the reset Hall electronic switch tube is in the on state, so that the voltage collected by the reset collection end of the lighting power controller is pulled down, thereby causing the reset collection end of the lighting power controller to maintain a low level, thereby facilitating the resetting of the lighting power controller at the specified trigger time and number of times, thereby facilitating the resetting of the lamps and modules connected to the lighting power controller.
[0026] See also Figure 1 , which is a circuit diagram of a lighting power reset circuit according to an embodiment of the present disclosure.
[0027] The lighting power reset circuit 10 of one embodiment includes a lighting power controller U1 and a magnetic induction conversion circuit 100. Please refer to Figure 2 , the magnetic induction conversion circuit 100 includes a reset Hall electronic switch tube D9, a first resistor R9 and a second resistor R10. The first end of the first resistor R9 is used to connect to the reference power supply +3V3, and the second end of the first resistor R9 is connected to the control end of the reset Hall electronic switch tube D9. The first end of the second resistor R10 is connected to the reference power supply +3V3, and the second end of the second resistor R10 is connected to the first end of the reset Hall electronic switch tube D9. The first end of the reset Hall electronic switch tube D9 is also connected to the reset collection end RESET of the lighting power controller U1, and the second end of the reset Hall electronic switch tube D9 is grounded.
[0028] In this embodiment, when the magnetic field around the reset Hall electronic switch tube D9 decreases, that is, the magnetic object is away from the reset Hall electronic switch tube D9, the reset Hall electronic switch tube D9 is in a cut-off state, so that the first end of the reset Hall electronic switch tube D9 maintains a high voltage, thereby causing the reset collection end RESET of the lighting power controller U1 to collect a high level; and when the magnetic field around the reset Hall electronic switch tube D9 increases, that is, the magnetic object is close to the reset Hall electronic switch tube D9, the reset Hall electronic switch tube D9 is in a conducting state, so that the voltage collected by the reset collection end RESET of the lighting power controller U1 is pulled down, thereby causing the reset collection end RESET of the lighting power controller U1 to maintain a low level, so that the lighting power controller U1 is reset at the specified trigger time and number of times, thereby facilitating the resetting of the lamps and various modules connected to the lighting power controller U1.
[0029] In another embodiment, by bringing a magnetic object close to the Hall device, the I / O input level of the wireless module is controlled by the internal reset Hall electronic switch tube. The wireless module first reads the pin input level and scans to obtain the switch value of this pin. At the same time, the input state is determined through program processing as single-click, double-click, long press, and super long press. The corresponding input events are constructed according to the different input states and put into the buffer. The calling cycle is 20ms. Each input event is read in the main loop, and different input events are responded to differently. In order to avoid the influence of the magnetic field in the transportation and construction environment of smart lighting products, different reset logics can be designed according to different projects to enhance the ability to adapt to the environment. For example: if a magnetic object is approached for 5 seconds, the lamp flashes once. If it is approached again within 10 seconds for 5 seconds, the lamp flashes once. If it is approached again within 10 seconds for 5 seconds, the lamp flashes three times, and the wireless module is reset. For details, see the attached Figure 3 .
[0030] In one embodiment, see Figure 2 The magnetic induction conversion circuit 100 further includes a first capacitor C14, and the first end of the reset Hall electronic switch tube D9 is grounded through the first capacitor C14. In this embodiment, the first capacitor C14 is connected to the reset Hall electronic switch tube D9. Specifically, the first capacitor C14 is connected in parallel between the first end and the second end of the reset Hall electronic switch tube D9, so that the first capacitor C14 grounds the signal on the first end of the reset Hall electronic switch tube D9, which is convenient for filtering the signal on the first end of the reset Hall electronic switch tube D9 to improve the accuracy of collecting the reset signal.
[0031] In another embodiment, the first capacitor C14 is a variable capacitor, and by adjusting the capacitance of the first capacitor C14, noise filtering in the signal at the first end of the reset Hall electronic switch tube D9 is made more accurate.
[0032] In one embodiment, see Figure 2 The magnetic induction conversion circuit 100 further includes a second capacitor C15, and the control end of the reset Hall electronic switch tube D9 is grounded through the second capacitor C15. In this embodiment, the second capacitor C15 is connected to the reset Hall electronic switch tube D9. Specifically, the second capacitor C15 is connected in parallel between the control end and the second end of the reset Hall electronic switch tube D9, so that the second capacitor C15 grounds the signal on the control end of the reset Hall electronic switch tube D9, which is convenient for filtering the signal on the control end of the reset Hall electronic switch tube D9, so as to improve the on-off control accuracy of the reset Hall electronic switch tube D9, thereby improving the acquisition accuracy of the reset signal.
[0033] In another embodiment, the second capacitor C15 is a variable capacitor, and by adjusting the capacitance of the second capacitor C15, noise filtering in the signal at the control end of the reset Hall electronic switch tube D9 is made more accurate.
[0034] In one embodiment, the resistance of the first resistor R9 is greater than or equal to the resistance of the second resistor R10. In this embodiment, the first resistor R9 is connected in series between the reference power supply +3V3 and the control end of the reset Hall electronic switch tube D9, and the second resistor R10 is connected in series between the reference power supply +3V3 and the first end of the reset Hall electronic switch tube D9. The voltage drop across the first resistor R9 is greater than the voltage drop across the second resistor R10, so that when the reset Hall electronic switch tube D9 is turned on, the control end of the reset Hall electronic switch tube D9 is reversely biased from the first end, so that the conduction of the reset Hall electronic switch tube D9 is continuous and stable.
[0035] In another embodiment, the first resistor R9 is an adjustable resistor, and / or the second resistor R10 is an adjustable resistor, so as to be applicable to different types of reset Hall electronic switch tubes D9.
[0036] In another embodiment, the reset Hall electronic switch tube D9 is of a model SOT23-3 / TO-92S.
