Description

Technical Field

[0001] This application relates to the field of LED lamp circuit technology, and more particularly to an emergency control circuit for LED lamps. Background Technology

[0002] LED lights are widely used in daily life due to their high efficiency and energy saving. Normally, simply connecting an LED light to a power source provides illumination. However, if the power grid fails, the LED light will stop working due to lack of power. Related technologies can incorporate main LED lights and emergency LED lights in LED lighting fixtures. The main lighting circuit powers the main LED lights, while the emergency lighting circuit powers the emergency LED lights. Since the main lighting circuit and emergency lighting circuit are two separate circuits, in the event of a power outage, the emergency lighting circuit needs to be installed into the main lighting circuit to maintain uninterrupted lighting through the emergency LED lights. Once the power grid is restored, the emergency lighting circuit needs to be manually disassembled to allow the main LED lights in the main lighting circuit to continue providing illumination. This process not only requires two LED lights but is also time-consuming, labor-intensive, and inefficient. Therefore, the ability to quickly achieve emergency control of LED lights is crucial.

Detailed Implementation

[0014] To make the above and other features and advantages of this application clearer, the application is further described below with reference to the accompanying drawings. It should be understood that the specific embodiments given herein are for the purpose of explanation to those skilled in the art, and are exemplary only, not restrictive.

[0015] In the following description, numerous specific details are set forth to provide a thorough understanding of this application. However, it will be apparent to those skilled in the art that the specific details are not required to practice this application. In other instances, well-known steps or operations have not been described in detail to avoid obscuring this application.

[0016] Figure 1 This is a circuit block diagram of an emergency control circuit for an LED light provided in this application.

[0017] refer to Figure 1 As shown, this application provides an emergency control circuit for an LED light, including a driver module, an emergency module, an LED light, and a switch control module.

[0018] The switch control module is connected to the drive module, the drive module is connected to the LED light, the emergency module is connected to the drive module, the drive module is connected to the mains power, and the emergency module includes a battery unit.

[0019] In addition, the driver module, also known as the power module, is used for power conversion and driving control of LED lights. It can be any device or component that can achieve this function, and this application does not limit it.

[0020] In addition, the switch control module may have one or more switching devices. The switching device may be any device that can realize switch control, such as a single-pole single-throw switch, a single-pole double-throw switch, a metal spring valve, or a pressure plate. This application does not limit this.

[0021] Optionally, the switch control module can be located inside the drive module or outside the drive module; this application does not limit this.

[0022] Therefore, in this embodiment of the application, the switch control module is configured to supply power to the LED light by the mains power grid through the drive module when the switch is closed, and to supply power to the LED light by the battery unit in the emergency module when the switch is open. In other words, by using the switch control module, emergency power supply to the LED light can be quickly realized without cumbersome switching, thereby simplifying the process and improving efficiency.

[0023] It should be noted that, Figure 1 The devices and connections shown are illustrative and can be adjusted as needed; this application does not impose any limitations on them.

[0024] In this embodiment, the emergency control circuit for an LED light may include a driver module, an emergency module, an LED light, and a switch control module. When the switch control module is closed, the driver module is connected to the power grid, directly using mains power to supply the LED light. When the switch control module is open, due to the interruption of mains power supply, power is supplied to the LED light through the emergency module. Therefore, when using the emergency module for power supply, no complex switching or installation steps are required; emergency lighting of the LED light can be quickly achieved through the switch control module, thus simplifying the operation process and improving the efficiency of emergency response.

[0025] Understandably, in Figure 1 Based on this, the switch control module may include a first switch device and a second switch device, which will be discussed below. Figure 2 The specific connection between the first switching device, the second switching device, and the drive module of the emergency control circuit for the LED lamp provided in this application is further explained.

[0026] The first end of the first switching device can be connected to the first connection terminal SL1 of the driving module, the second end of the first switching device can be connected to the second connection terminal Lout1 of the driving module, the first end of the second switching device can be connected to the third connection terminal In1+ of the driving module, and the second end of the second switching device can be connected to the fourth connection terminal LED1+ of the driving module.

[0027] The first and second switching devices can be any controllable switching devices such as single-pole single-throw switches, single-pole double-throw switches, metal spring valves, and pressure plates; this application does not limit them.

[0028] It is understandable that when the first switch is closed, the SL pin and the Lout pin are connected and turned on through the first switch. When the second switch is closed, the In+ pin and the Led+ pin are connected and turned on through the second switch. Therefore, when both the first and second switches are closed, the driver module is connected to the power grid and can directly use AC power to power the LED.

[0029] Optionally, mains power can be connected to the switch control module via the L live wire, which in turn powers the LED light through the driver module. For easier understanding with the accompanying diagram, Figure 2 This connection is not shown in the text.

[0030] Optionally, the emergency module may include a battery unit.

[0031] Specifically, the first connection terminal LED2+ of the emergency module is connected to the first connection terminal of the battery unit and the fourth connection terminal LED1+ of the drive module, respectively, and the second connection terminal LED2- of the emergency module is connected to the second connection terminal of the battery unit and the fifth connection terminal LED1- of the drive module, respectively.

[0032] The first connection terminal of the battery unit is the input terminal of the battery unit, and the second connection terminal of the battery unit is the output terminal of the battery unit.

[0033] In addition, the battery cell can be a battery cell containing a lithium battery, or it can be other battery cells that can store electrical energy and provide power; this application does not limit this.

[0034] Optionally, when both the first and second switching devices are disconnected, the emergency module and the drive module are electrically connected via pins. For example... Figure 2As shown, the Nout2 pin of the emergency module is connected to the Nout1 pin of the driver module; the Lin2 pin of the emergency module is connected to the Lin1 pin of the driver module; the SL2 pin of the emergency module is connected to the SL1 pin of the driver module; the Lout2 pin of the emergency module is connected to the Lout1 pin of the driver module; the In2- pin of the emergency module is connected to the In1- pin of the driver module; the In2+ pin of the emergency module is connected to the In1+ pin of the driver module; the LED2- pin of the emergency module is connected to the LED1- pin of the driver module; and the LED2+ pin of the emergency module is connected to the LED1+ pin of the driver module. Since the fourth connection terminal LED1+ and the fifth connection terminal LED1- of the driver module are connected to the LED+ and LED- of the LED light respectively, when the emergency module and the driver module are electrically connected through each pin, the battery unit in the emergency module can power the LED light. This allows for LED power supply and lighting when the mains power is unavailable, and the operation is relatively simple and quick.

[0035] Optionally, in the emergency control circuit of the LED light, components can be added, deleted, or adjusted according to actual needs. For example, an indicator light detection unit can be set up, such as... Figure 2 The indicator test unit in the code; or you can set up a circuit self-test unit, such as... Figure 2 This application does not limit the scope of the dip switch unit, etc.

[0036] It should be noted that, Figure 2 The devices and connections shown are illustrative and can be adjusted as needed; this application does not impose any limitations on them.

[0037] Optionally, the LED light may include a first LED and a second LED, and the driver module may include a third switching device.

[0038] In this configuration, the first terminal of the third switching device is connected to the first LED bead, the second terminal of the third switching device is connected to the second LED bead, and the third terminal of the third switching device is connected to the fifth connection terminal LED1- of the driver module. The first and second LED beads have different color temperatures.

[0039] In addition, the color temperature of the first and second LEDs can have various values, such as the first LED being 3000K and the second LED being 5000K, or the first LED being 6500K and the second LED being 2700K, or other color temperature values. This application does not limit these values.

[0040] In addition, the third switching device can be a double-pole double-throw switch, or a three-terminal relay, or any switching device that switches between the first and second LED beads, etc. This application does not limit this.

[0041] It is understandable that when the third switching device is connected to the first LED, the first LED is in operation, and illumination is provided according to its color temperature. For example, if the color temperature of the first LED is 3000K, the illumination color temperature is 3000K. Alternatively, when the third switching device is connected to the second LED, the second LED is in operation, and illumination is provided according to its color temperature. For example, if the color temperature of the second LED is 5000K, the illumination color temperature is 5000K. Or, when the third switching device is connected to both the first and second LEDs, both LEDs are in operation, and the color temperatures of both LEDs contribute to the illumination. For example, if the first LED is 3000K and the second LED is 5000K, and the third switching device is connected to both, the illumination color temperature is a mixture of the two LEDs. This application does not limit this.

[0042] Therefore, in this embodiment of the application, the color temperature switching of the LED lamp can be controlled by a third switching device. Thus, the color temperature control of the LED lamp can be made more convenient through the emergency control circuit of the LED lamp, reducing the process and improving efficiency.

[0043] Optionally, the drive module also includes a fourth switching device, the first end of which is connected to the fourth connection terminal LED1+ of the drive module, and the second end of which is connected to the LED.

[0044] The fourth switching device is configured to switch the LED power via the drive module when it is in the closed state.

[0045] It is understood that the fourth switching device can be any switching element capable of controlling the on / off state of a circuit, such as a metal-oxide-semiconductor field-effect transistor or a thyristor. Therefore, in this embodiment, the fourth switching device allows for relatively simple switching between different power levels of the LED lamp, enabling rapid adjustment of the LED lamp's brightness.

[0046] Optionally, the drive module may include a rectifier unit. The input terminal of the rectifier unit is connected to the mains power supply, and the output terminal of the rectifier unit is connected to the first connection terminal of the drive module.

[0047] Understandably, a rectifier unit, as a power conversion device, typically contains one or more rectifiers to convert alternating current (AC) to direct current (DC). The rectifier unit can also perform voltage regulation to ensure a stable output voltage, unaffected by input voltage fluctuations.

[0048] Therefore, in this embodiment, the AC mains power is converted into DC power compatible with the LED lamp by the rectifier unit, thereby ensuring the reliable operation of the LED lamp and avoiding performance instability or damage caused by input voltage fluctuations. Furthermore, the voltage regulation function of the rectifier unit further ensures the stability of the output voltage, reduces power supply noise and ripple, thereby extending the lifespan of the LED lamp and improving the stability and reliability of the entire LED lamp emergency control circuit.

[0049] Optionally, the driver module also includes an overcurrent protection unit. The first connection terminal of the overcurrent protection unit is connected to the fourth connection terminal LED1+ of the driver module, and the second connection terminal of the overcurrent protection unit is connected to the LED.

[0050] The overcurrent protection unit can be a fuse, a thermistor, etc., which is limited in this application.

[0051] Therefore, in this embodiment of the application, the overcurrent protection unit can automatically disconnect the circuit when the current exceeds the preset safety value, thereby protecting the LED lamp and the driver module from damage and improving the safety and reliability of the circuit.

[0052] Optionally, the emergency module may include a switching diode.

[0053] One end of the switching diode is connected to the first connection terminal LED2+ of the emergency module, and the other end is connected to the third connection terminal In2+ of the emergency module.

[0054] Understandably, switching diodes can be used to prevent reverse current flow, avoiding situations such as damage to the emergency module due to reverse current flow, thereby ensuring the correct direction of current flow, preventing potential circuit damage, and thus helping to improve the safety and reliability of LED light emergency control circuits.

[0055] Optionally, the emergency module may also include a power supply unit, which connects the battery unit to LED+ and powers the LED light through the LED+ of the driver module.

[0056] Optionally, the emergency module can also be equipped with a charging unit, which can charge the battery unit when the grid power is sufficient, ensuring that the charging unit has sufficient power and can then power the LED lights in an emergency.

[0057] Understandable, Figure 3 This is a connection diagram of the drive module, emergency module, LED light and switch control module. Figure 3 The devices and connection methods shown are for illustrative purposes only, and the connection relationships between the various circuit devices are only partially shown. They should not be taken as a limitation on the connection relationships between the various circuit devices in the embodiments of this application.

[0059] In this embodiment, the emergency control circuit for an LED light may include a driver module, an emergency module, an LED light, and a switch control module. When the switch control module is closed, the driver module is connected to the power grid, directly using mains power to supply the LED light. When the switch control module is open, due to the interruption of mains power supply, power is supplied to the LED light through the emergency module. Therefore, when using the emergency module for power supply, no complex switching or installation steps are required; emergency lighting of the LED light can be quickly achieved through the switch control module, thus simplifying the operation process and improving the efficiency of emergency response.
