In emergency work, the battery generates a 3.3V voltage for power supply through the voltage regulator chip of the single-chip microcomputer circuit. Among the pins used by the single-chip microcomputer in the single-chip microcomputer circuit, two of them are the 3.3V power supply pins of the single-chip microcomputer; two of them are the TXD and RXD of the serial interface, the data sending and receiving pins, which are connected to the RXD and TXD of the LoRa module circuit respectively, and realize data transparent transmission with the LoRa module circuit; one of the pins is the indicator light control pin, which is connected to the indicator light of the auxiliary control board, and the I / O of the single-chip microcomputer is connected.

One of the pins is a built-in battery voltage detection pin. The battery voltage is sampled through the resistor voltage divider to obtain the battery voltage information as a basis for judging whether the emergency charging and emergency work and emergency test conditions are met. The criteria for determining whether the power supply is satisfied are as follows: one of the pins is the normal power supply detection pin.

Press and hold the test button for 5 seconds to reset the automatic detection program timer to zero.

[0009] The LoRa gateway stores the test result information data and saves it to the database through the computer terminal. The LoRa module circuit receives the 30-second or 90-minute emergency function test instruction of the LoRa gateway and performs a real-time emergency function test, and uploads the test results in real time.

[0010] The indicator light shows the working mode and automatic detection status of the emergency light, which are shown as follows:

[0044] Refer to Figures 1 to 10 , which illustrate a non-mobile indoor LED emergency light designed to work with a LoRa gateway. The design comprises an AC control device 1, a light source assembly 2, an emergency control device 3, a battery 4, an auxiliary control board 5, and a power input interface 6. The AC control device 1 controls the light source assembly 2 during normal grid power supply, effectively driving it. The emergency control device 3 controls the light source assembly 2 during an emergency. The light source assembly 2 serves as the lighting component of the entire emergency light fixture. The auxiliary control board 5 is used for emergency testing and other functions. These components control the lamp to perform an automatic emergency function test for 30 seconds monthly and / or 90 minutes annually. They also control the output of the normally operating AC control device 1 to shut off, switching power to the emergency control device 3 to supply the LED load. The LED operating voltage is tested to determine if emergency operation is normal. The battery 4 voltage is continuously tested to determine if it meets regulatory requirements. In actual applications, the number, shape, structure, and coordination of these components can be optimized and adjusted, and existing components can be used to replace them.

[0045] The AC control device 1 shown in the figure utilizes a conventional isolated constant-current LED driver. Under normal power supply conditions, it drives the LED load to illuminate. The AC control device 1's power input is achieved through two pins on the lamp holder 61 at one end of the power input interface 6. The AC control device 1 can also control the light on and off via a wall switch. As shown in the figure, a transistor circuit 831 composed of transistors Q6 and Q5, controlled by pin 10 of chip U4 in Figure 6, is connected between the output of the AC control device 1 and the LED load. During emergency testing, the output of the AC control device 1 is disconnected from the LED load. Please refer to the figure for the detailed circuit layout of the AC control device 1. In actual applications, other isolated constant-current LED driver power supplies can be used in place of the aforementioned driver power supply. Accordingly, the transistors Q6 and Q5 circuits can be replaced with other circuits with equivalent functions.

[0046] The light source assembly 2 in the figure is mainly the light-emitting part of the lamp, which has conventional components such as a lampshade 21, an LED light source module 22, and a radiator 23. The lampshade 21 adopts a conventional light-transmitting PC cover structure, and the LED light source module 22 adopts LED lamp beads, an aluminum substrate, and other structures. The lamp holder 61 has two power input interfaces 6 that form the lamp and is installed at both ends of the aluminum radiator 23 of the light source assembly 2. Each of the above lamp holders 61 has two pins, and the lampshade 21 is installed on the aluminum radiator 23 of the light source assembly 2. The AC control device 1, emergency control device 3, battery 4, and auxiliary control board 5 in the figure are all installed in the manner shown in the figure and fixed to the light source assembly 2. It should be noted that in other applications, such as when applied to other lamps, the lamp holder 61 does not necessarily need to be used. It can be equivalently replaced with other components that can serve as the power input terminal to replace the power input interface 6. In actual applications, other existing components can also be used to equivalently replace the above components or to optimize the design of the above components.

[0047] The power input of the emergency control device 3 shown in the figure is achieved through two pins of the lamp holder 61 at the other end of the power input interface 6. The emergency control device 3 charges the battery 4 during normal power supply. When a power failure occurs, the battery 4 controls the power supply to enable the LED load to continue operating. At this time, the operating power of the LED load is lower than the LED load power during normal power supply. The emergency control device 3 is designed with a constant voltage drive circuit 81, an emergency operating circuit 82, a single-chip microcomputer circuit 83, and a LoRa module circuit 84. Please refer to the figure for the specific circuit layout.

[0048] The constant voltage drive circuit 81 is a conventional circuit scheme, used to charge the battery 4 and provide power to the microcontroller (MCU) and LoRa module circuit 84 in the MCU circuit 83 during normal operation. The emergency operation circuit 82 is powered by the battery 4. Based on existing circuit schemes, the MCU controls a pin (numbered 10) to output a high level to the DIM pin of the emergency operation circuit 82 chip, thus activating the LED load of the light source assembly 2 in an emergency state.

[0049] During normal operation, the microcontroller circuit 83 receives a 3.3V voltage from the constant voltage drive circuit 81 via the microcontroller's voltage regulator chip. During emergency operation, the microcontroller circuit 83 receives a 3.3V voltage generated by the battery 4 via the microcontroller's voltage regulator chip. Among the I / O pins used by the microcontroller circuit 83, pins numbered 2 and 3 are the serial interface's TXD and RXD data transmission and reception pins, respectively, connected to the RXD and TXD pins of the LoRa module circuit 84, enabling transparent data transmission with the LoRa module circuit 84. Pin numbered 7 is the indicator light 52 control pin, connected to the indicator light 52 on the auxiliary control board 5. This I / O pin outputs signals from the microcontroller, causing the LED indicator light 52 to display different operating states. Pin numbered 8 is the test button 53 trigger pin, connected to the test button 53 on the auxiliary control board 5, receiving trigger signals from the test button 53 via this microcontroller I / O pin. During normal power supply, pin 10 of microcontroller circuit 83 outputs a high level to the base of transistor Q6, turning on transistor Q6. The AC control device 1 output voltage, LED1+, is then applied to the gate and source of transistor Q5 via the voltage divider created by R18, turning on transistor Q5. The AC control device 1 output voltage, LED1+, is then applied to the LED load, LED+, enabling normal operation. During emergency testing, this pin outputs a low level to the base of transistor O6, turning off transistor Q6. The voltage divider created by R18, LED1+, applied to the gate and source of transistor Q5, is lost, turning off transistor Q5 and disconnecting the AC control device 1 output voltage, LED+, from the LED load. Pin 11 is the emergency operation control pin. In emergency operation mode, this I / O pin outputs a high level to the DIM pin of the emergency control circuit chip, activating emergency operation circuit 82 and controlling the LED load to illuminate, thus entering emergency operation mode. During normal power supply, the emergency control pin (numbered 12) of the microcontroller circuit 83 outputs a high level to the base of transistor Q3, turning on transistor Q3. The constant-voltage drive circuit's output voltage is applied to the gate and source of transistor Q4 via the voltage divider generated by resistor R13, turning on transistor Q4 and enabling the constant-voltage drive circuit to output voltage to charge the battery. When battery 4 is charged to a certain value, the emergency control pin (numbered 12) outputs a low level to the base of transistor Q3, turning off transistor Q3. The constant-voltage drive circuit's output voltage applied to the gate and source of transistor Q4 is lost via the voltage divider generated by resistor R13, turning off transistor Q4 and ceasing charging of battery 4. Pin 13 is the LED load operating voltage detection pin. The LED load voltage is sampled via resistor voltage divider to obtain information about the LED load operating voltage, which serves as a basis for determining whether the emergency function is functioning properly.Pin 14 is the built-in battery 4 voltage detection pin. The battery 4 voltage is sampled through a resistor divider to obtain battery 4 voltage information, which serves as the basis for judging whether the emergency charging, emergency work, and emergency test conditions are met. Pin 15 is the normal power supply detection pin. When the power is normally supplied, the emergency drive circuit outputs a voltage, turning on transistor Q2. This detection pin pulls down to generate a low-level signal. The introduction of the above pins clearly expresses the coordination between the chip and other circuits or components. Through the above configuration, the chip of the single-chip microcomputer circuit 83 can realize monthly and annual automatic emergency function detection, performing a 30-second emergency test once a month and a 90-minute emergency test once a year to simulate whether the emergency function can be switched to work when a power failure occurs, so as to meet regulatory requirements.

[0050] The LoRa module circuit 84 receives 3.3V power through a circuit board and connector, while transparently transmitting data with the serial interface of the microcontroller circuit 83. The LoRa module circuit 84 is connected to the spring antenna 54 on the auxiliary control board 5 via a communication line. Specifically, the LoRa module circuit 84 can be electrically connected using existing methods such as adding connectors and shielded wires, thereby achieving LoRa wireless communication of data and instructions with the gateway. It can also exchange data and instructions with user devices, conveniently providing users with fast self-organizing network access and wireless data services. The specific communication protocol of the LoRa module circuit 84 can refer to existing technologies and technical standards. To facilitate observation and data exchange with the host control computer 9, the LoRa module circuit 84 can communicate with external devices outside the lamp, such as the LoRa gateway 7. The LoRa gateway 7 also has a wireless communication module, chip, and data storage unit, corresponding to the communication module on the LoRa module circuit 84.

[0051] The LoRa gateway 7 wirelessly communicates with the emergency lights to upload and download data. The LoRa gateway 7 maintains coordination with host computer software, enabling data exchange between the host computer software and the LoRa gateway 7 via a wired network. In practical applications, multiple LoRa modules 84 can be paired with one LoRa gateway 7. The number of LoRa modules 84 and LoRa gateways 7 is N:1, meaning multiple emergency lights are paired with one LoRa gateway 6, with N ≤ 200. The LoRa gateway 7 stores test results and saves them to a database via the control computer 9. The LoRa modules 84 receive the 30-second or 90-minute emergency function test instructions from the LoRa gateway 7, performing real-time emergency function testing and uploading the test results in real time. At the same time, a barcode can be affixed to the emergency light to keep it the same as the MAC address of the wireless communication module in the emergency light. In this way, the mobile phone app can obtain the MAC address of the wireless communication module by scanning the barcode on the emergency light. The location information of the emergency light installation can be entered and the data can be saved and sent to the mailbox. This data is imported through the upper computer software to realize the management of the MAC address, location information and test results of the emergency light.

[0052] The battery 4 in the figure is a conventional component, which supplies power to the emergency control device 3 in an emergency state. The size of the battery 4 can be adjusted and optimized as needed.

[0053] The auxiliary control panel 5 shown in the figure is fixed to the slot of the aluminum heat sink 23, such as an aluminum profile, and is further secured by the lamp holder 61. The auxiliary control panel 5 is electrically connected to the emergency control device 3 via a set of electronic wiring harnesses. The auxiliary control panel 5 is designed with a toggle switch 51, an indicator light 52, a button 53, and an antenna 54. The toggle switch 51 works with the battery 4 to disconnect and connect it. It is factory-set to the off position ("OFF"). The user should turn the switch to the on position ("ON") before use. The indicator light 52 displays the emergency light's operating mode and automatic test status, specifically: a. Steady on, indicating normal power supply and normal test; b. Off, indicating a power supply failure; c. Slow flashing mode 1 (on for 1 second / off for 0.3 seconds for 15 seconds), indicating that the internal battery 4 is insufficiently charged or unsuitable for manual testing; d. Slow flashing mode 2 (on for 1 second / off for 3 seconds), indicating that the emergency test is in progress; e. Fast flashing (on for 0.5 seconds / off for 0.5 seconds), indicating an abnormal test. Button 53 is used for a manual emergency test. Pressing test button 53 once within 3 seconds initiates a 30-second automatic emergency test. Pressing test button 53 twice within 3 seconds initiates a 90-minute automatic emergency test. During any manual test, pressing test button 53 once terminates the automatic detection control system. Pressing test button 53 for 5 seconds resets the automatic detection program time to zero. Antenna 54 is a spring antenna 54, used for transmitting and receiving signals from the LoRa module circuit 84. This antenna 54 can be soldered to the control board near the lamp head 61, below the lampshade 21. This antenna 54 connects to the LoRa module circuit 84 via a shielded cable. One end of the shielded cable has a shielded terminal that interlocks with the patch terminal on the emergency control device 3, electrically connecting it to the receiving end of antenna 54. The other end, without a shielded terminal, is soldered to the auxiliary control board 5, electrically assembling it to the antenna 54 on the auxiliary control board 5. Alternatively, the other end, with a shielded terminal, interlocks with the patch terminal on the control board, electrically connecting it to the antenna 54 on the auxiliary control board 5.
