Description

An LED emergency power supply adaptable to built-in drivers Technical Field

[0001] This utility model relates to the field of emergency lighting technology, and in particular to an LED emergency power supply that can be adapted to a built-in driver. Background Technology

[0002] Currently, emergency power supplies for LED emergency lighting mainly fall into two categories: centralized emergency power supplies and independent emergency power supplies. Centralized emergency power supplies are installed within buildings to provide backup power to multiple LED emergency lights in the event of a power outage or failure of normal lighting. However, when these LED emergency lights are simultaneously used as normal lighting fixtures, they typically share the same normal lighting power supply line. Therefore, they are not suitable for emergency scenarios where the normal lighting power supply line is interrupted due to fire or other disasters. Consequently, independent emergency power supplies remain widely used in existing emergency lighting systems.

[0003] However, the wiring method of existing independent LED emergency power supplies is not compatible with LED lights that generally have built-in integrated driver power supplies on the market. This results in LED emergency lighting lights being unable to be adapted when replaced or upgraded, leading to higher production and maintenance costs. Summary of the Invention [Summary of the Utility Model]

[0004] To address the technical problem that current LED emergency power supply wiring methods are incompatible with commercially available LED lights that have built-in drivers, resulting in high production and maintenance costs, this utility model provides an LED emergency power supply that is compatible with built-in drivers.

[0005] To achieve the above objectives, this utility model is implemented by the following technical solution:

[0009] An emergency power supply includes a wiring port, a battery pack, and an inverter unit. The wiring port includes an input connection terminal, an output connection terminal, and a control connection terminal. Mains power is connected to one end of the input connection terminal, and the other end of the input connection terminal is connected to the input terminal of the inverter unit. The output terminal of the inverter unit is connected to the input terminal of the battery pack. The output terminal of the battery pack is connected to one end of the output connection terminal, and the other end of the output connection terminal is connected to the input terminal of the drive power supply. The battery pack charges and stores energy when the mains power is normal, and provides emergency power to the LED light source when the mains power fails.

[0010] By adopting the above technical solution and setting the wiring ports, the emergency power supply can be adapted to a variety of LED lights with built-in integrated driver power supplies on the market. This means that when repairing or upgrading LED emergency lights, no additional modifications to the emergency power supply are required. This allows users to choose different specifications and models of LED lights according to their needs, reducing maintenance costs and improving its compatibility and flexibility.

[0011] Secondly, when the mains power fails, the emergency power supply can provide stable emergency power to the LED light source, ensuring continuous lighting even in emergencies, facilitating people's evacuation, search for emergency equipment, or waiting for rescue.

[0015] As described above, an LED emergency power supply adaptable to a built-in driver further includes an indicator unit, the indicator unit comprising:

[0016] The first indicator light is electrically connected to the main control unit. The first indicator light is used to light up when the battery pack is charging and turn off when the battery pack is fully charged.

[0031] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] A specific embodiment, in conjunction with Figures 1 to 5, further illustrates the technical solution of this utility model: an LED emergency power supply adaptable to a built-in driver, comprising an LED light source 1, a driver power supply 2, and an emergency power supply 10. The output terminal of the driver power supply 2 is connected to the LED light source. The emergency power supply 10 includes a wiring port 11, a battery pack 12, and an inverter unit 13. The wiring port 11 includes an input connection terminal, an output connection terminal, and a control connection terminal. The mains power is connected to one end of the input connection terminal, and the other end of the input connection terminal is connected to the input terminal of the inverter unit 13. The output terminal of the inverter unit 13 is connected to the input terminal of the battery pack 12. The output terminal of the battery pack 12 is connected to one end of the output connection terminal, and the other end of the output connection terminal is connected to the input terminal of the driver power supply 2. The battery pack 12 charges and stores energy when the mains power is normal, and provides emergency power to the LED light source 1 when the mains power fails.

[0033] The input connection terminal of the wiring port 11 includes a live wire connection terminal and a neutral wire connection terminal, and the output connection terminal of the wiring port 11 includes a negative terminal and a positive terminal.

[0034] In this embodiment, by setting the wiring port, the emergency power supply can be adapted to a variety of LED lights with built-in integrated driver power supplies on the market. This means that when repairing or upgrading LED emergency lights, no additional modifications to the emergency power supply are required. This allows users to choose different specifications and models of LED lights according to their needs, reducing maintenance costs and improving its compatibility and flexibility.

[0035] Secondly, when the mains power fails, the emergency power supply can provide stable emergency power to the LED light source, ensuring continuous lighting even in emergencies, facilitating people's evacuation, search for emergency equipment, or waiting for rescue.

[0036] In a preferred embodiment, the power of the LED light source does not exceed 30W. Preferably, the power of the LED light source in this embodiment is 5-25W.

[0037] As a preferred implementation, as shown in Figure 5, a circuit implementation of an emergency power supply and an LED light with a built-in driver is provided. The live wire of the mains power is connected to the live wire connection terminal (i.e., L terminal) of the emergency power supply 10, the neutral wire of the mains power is connected to the neutral wire connection terminal (i.e., N terminal) of the emergency power supply 10, the positive terminal of the emergency power supply 10 is connected to the live wire connection terminal of the driver power supply 1, the negative terminal of the emergency power supply is connected to the neutral wire connection terminal of the driver power supply, the positive terminal of the driver power supply 1 is connected to the positive terminal of the LED light source 2, and the negative terminal of the driver power supply 1 is connected to the negative terminal of the LED light source 2.

[0038] The live wire of the mains power is also connected to one end of the control switch, and the other end of the control switch is connected to the control terminal of the emergency power supply.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation, the emergency power supply 10 also includes a main control unit 14. The signal input terminal of the main control unit 14 is connected to the output terminal of the inverter unit 13, and the signal output terminal of the main control unit 14 is connected to the input terminal of the battery pack 12. The main control unit 14 is used to control the battery pack to continuously and fully output emergency power when the mains power fails, so that the LED light source always maintains the highest brightness.

[0040] Specifically, when the mains power fails (e.g., a power outage), the main control unit 14 receives a voltage signal from the inverter unit 13 that is different from the normal output voltage signal. At this time, the main control unit 14 outputs a first control signal to control the battery pack 12 to continuously output emergency power. That is, the emergency power supply is in emergency mode. In emergency mode, the battery pack 12 will output full power, so that the LED light source 1 will work continuously at full power and maintain the brightest brightness. During this period, if the mains power returns to normal, the main control unit 14 receives a voltage signal from the inverter unit 13 that is the normal output voltage signal. At this time, the main control unit 14 outputs a second control signal to control the battery pack 12 to stop outputting emergency power. That is, the emergency power supply is in normal mode, and the battery pack 12 will charge and store energy.

[0041] In this embodiment, the main control unit monitors the status of the mains power in real time. When the mains power fails, it can promptly control the emergency power supply to switch to emergency mode, ensuring continuous illumination of the LED light source to meet lighting needs in emergencies and improve the reliability of emergency lighting. At the same time, after the mains power is restored, it can control the emergency power supply to switch back to normal mode to prevent the battery pack from continuing to discharge after the mains power is restored, thus preventing excessive discharge of the battery pack and preventing interference caused by the simultaneous power supply of the mains power and battery pack discharge to the LED light source, ensuring the stability and safety of the circuit.

[0042] Alternatively, the main control unit 14 can be implemented using a main controller, such as an MCU (Microcontroller Unit), DSP (Digital Signal Processor), FPGA (Field Programmable Gate Array), or SOC (System On Chip).

[0043] Furthermore, as a preferred embodiment of this solution and not a limitation, the emergency power supply 10 is also provided with a control switch 15. One end of the control switch 15 is connected to the mains power, and the other end of the control switch 15 is connected to one end of the control connection terminal. The other end of the control connection terminal is connected to the control terminal of the main control unit 14. The control switch 15 is used to control the LED light source to turn on / off when the mains power is normal.

[0044] When the mains power is normal, the user can control the LED light source to turn on or off through the control switch 15. When the LED light source is turned off, it does not affect the charging and energy storage of the battery pack 12. That is, if the battery pack 12 is not fully charged at this time, the battery pack 12 will continue to charge until it is fully charged, even if the LED light source is turned off.

[0045] In the event of a mains power failure, the LED light source will not be controlled by the control switch 15 and will continue to illuminate until the battery pack 12 reaches a low power level, at which point it will turn off.

[0046] In this embodiment, when the mains power is normal, the user can flexibly turn the LED light source on or off according to actual needs by controlling the switch, thereby saving energy. At this time, the battery pack is not affected by the LED light source status. As long as the mains power is normal, the battery pack will continue to charge until it is fully charged, ensuring that the battery pack is always fully charged and ready to provide emergency power when the mains power fails, thus improving the reliability and backup performance of the emergency power supply.

[0047] Secondly, when the mains power fails, the LED light source will automatically turn on and continue to illuminate the circuit until the battery is depleted, ensuring lighting needs in emergencies and improving the reliability and safety of emergency lighting.

[0048] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the emergency power supply further includes an indicator unit, the indicator unit comprising:

[0049] The first indicator light is electrically connected to the main control unit. The first indicator light is used to light up when the battery pack is charging and turn off when the battery pack is fully charged.

[0050] The second indicator light is electrically connected to the main control unit. The second indicator light is used to light up when the mains power is normal and turn off when the mains power fails.

[0051] The third indicator light is electrically connected to the main control unit. The third indicator light is used to light up when the battery pack provides emergency power to the LED light source and to turn off when the battery pack is charging and storing energy.

[0052] The first, second, and third indicator lights are all different colors to distinguish the current status of the emergency power supply.

[0053] In a preferred embodiment, the first indicator light can be red, the second indicator light can be green, and the third indicator light can be blue. It is understood that this embodiment is only a preferred method, and adjustments can be made according to requirements in actual use; this embodiment does not impose specific limitations.

[0054] In this embodiment, users can quickly determine the status of the emergency power supply and the mains power by observing the on / off status of the indicator lights, thus providing a direct basis for troubleshooting, shortening maintenance time, and improving equipment reliability.

[0055] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, it also includes a protective housing 16 for providing protection for the emergency power supply, the protective housing comprising a first housing 161 and a second housing 162.

[0056] In a preferred embodiment, the first housing 161 and the second housing 162 are made of iron.

[0057] In this embodiment, the first housing and the second housing together form a closed protective space, which can effectively prevent dust and debris from entering the emergency power supply and avoid contamination or damage to the internal components. At the same time, both the first housing and the second housing are iron shells, which can effectively prevent external electromagnetic interference from entering the emergency power supply and ensure the stable operation of the internal circuits and components. In addition, iron has good thermal conductivity, which helps to improve heat dissipation and ensure that the emergency power supply operates normally within the normal temperature range.

[0058] Those skilled in the art should understand that the above description is one embodiment provided in conjunction with specific content, and does not imply that the specific implementation of this utility model is limited to these descriptions. Furthermore, due to differences in industry naming conventions, it is not limited to the above names or English names.
