Description

Technical Field

[0001] The invention relates to the field of emergency power supplies, and in particular to an emergency power supply system and an emergency power supply thereof. Background Art

[0002] Emergency lighting is a lighting fixture that is activated when the power supply of normal lighting is cut off / failed. Considering factors such as cost and installation and use, emergency lighting is generally used as normal lighting at the same time. Under normal conditions, emergency lighting is powered by the mains and used as normal lighting. Under abnormal conditions, that is, when the power supply of normal lighting is cut off / failed, batteries or generators are used to power emergency lighting to provide lighting. The emergency power supply system of existing LED emergency lights includes emergency power supply and driving power supply, and generally has two solutions.

[0003] Specifically, refer to the present invention application Figure 1A and Figure 1B As shown, the wiring methods of the two existing emergency lamps are respectively shown, wherein the corresponding Figure 1A The emergency lighting fixture includes an emergency power supply 10P, a driving power supply 20P and at least one LED lamp bead 30P, wherein the LED lamp bead 30P is powered and connected to the driving power supply 20P, wherein the driving power supply 20P is electrically connected to the emergency power supply 10P, wherein the emergency power supply 10P is electrically connected to the live wire and the neutral wire of the mains and has two circuits, wherein one circuit converts the alternating current connected from the mains into direct current to charge the battery inside the emergency power supply 10P and to power the processor, wherein the other circuit powers the driving unit 20P through the relay inside the emergency power supply 10P to realize the driving power supply 20P to power the LED lamp bead 30P for lighting, and at this time, the lighting power of the LED lamp bead 30P is determined by the driving unit 20P itself. When the emergency power supply 10P cannot detect the AC input, the inverter is turned on to invert the specific voltage of the battery output to the driving power supply 20P, wherein the emergency power supply 10P is also provided with a 0-10V dimming circuit. In an abnormal situation, the inverter uses the 0-10V dimming circuit to adjust the lighting power of the emergency lamp to save energy consumption. Therefore, the use of the emergency power supply 10P requires that the driving power supply 20P has a 0-10V dimming port. For common LED lamps such as bulb lamps and T8 lamp tubes, they are usually built-in with the driving power supply 20P. Due to their small size, these LED lamps do not have the conditions for setting a dimming port. Therefore, the above wiring method cannot be directly compatible with the LED lamps on the market that are generally built-in with the driving power supply 20P. In addition, the above wiring method cannot be applied to LED lamp panels, and the application scenarios are limited.

[0004] which corresponds to Figure 1B , the LED lamp beads 30P of the emergency lamp are respectively connected to the emergency power supply 10P and the driving power supply 20P. The driving power supply 20P is electrically connected to the emergency power supply 10P. When the normal mains power is supplied, the driving unit 20P is powered by the relay inside the emergency power supply 10P to realize lighting. At this time, the lighting power is determined by the driving unit 20P itself. When the emergency power supply 10P cannot detect the AC input, the electric energy output by the battery is boosted and directly supplied to the LED lamp beads 30P. At this time, the lighting power of the LED lamp beads 30P is determined by the emergency power supply 10P. However, this wiring method is only applicable to the emergency wiring of LED light panels, and is not applicable to common lamps on the market such as lamp tubes, bulbs, and UFO lamps.

[0005] And because the mains voltage in different regions is not the same, for example, the voltage standard adopted by China is 220V, the voltage standard adopted by Europe is 230V, and the voltage standard adopted by the United States is 110V and 277V. Therefore, lamps in different regions are also set to adapt to different working voltages. Therefore, if lamps in different regions are to be configured for emergency, different emergency power supplies need to be selected, and emergency power supply manufacturers also need to design different emergency power supplies for different shipping areas.

Therefore, the above terms should not be understood as limiting the present invention.

[0050] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0051] The present invention provides an emergency power supply system, wherein the emergency power supply system can automatically match the output voltage according to the input voltage. The output voltage of the emergency power supply system is adjustable and can improve the adaptability and compatibility with different driving power supplies, which is conducive to compatibility with most LED lamps on the market so that LED lamps can be transformed into emergency lamps, and facilitates the installation and application of the emergency power supply system.

[0052] For example, referring to the accompanying drawings of the present invention, Figures 2 to 5, an emergency power supply system 100 and its emergency power supply 10 according to an embodiment of the present invention are respectively illustrated, wherein the emergency power supply 10 is connected to the live wire L and the neutral wire N so as to be able to access electric energy, and in the state where the live wire L and the neutral wire N are not powered normally, the emergency power supply 10 outputs emergency electric energy using its own energy storage, so that the emergency power supply 10 has a normal power supply state corresponding to the normal power supply of the live wire L and the neutral wire N, and an emergency power supply state where the live wire L and the neutral wire N are not powered normally. The emergency power supply 10 has a voltage detection circuit 11 to detect the input voltage value of the emergency power supply 10 in the normal power supply state, wherein the emergency power supply 10 is configured to automatically match the output voltage in the voltage range of 20V to 400V in the emergency power supply state based on the input voltage value, for example, outputting 170VDC when the input is 120VAC, and outputting 385VDC when the input is 277VAC, so as to be able to output a suitable voltage to power the driving power supply 20, and is suitable for use in areas with different voltage standards.

[0053] Specifically, the emergency power supply system 100 includes the driving power supply 20 and at least one LED lamp bead 30, wherein the driving power supply 20 has two input terminals 21 and 22, a positive output terminal 23 and a negative output terminal 24, wherein the emergency power supply 10 has two output terminals 101 and 102 respectively electrically connected to the two input terminals 21 and 22 of the driving power supply 20, wherein the LED lamp bead 30 is powered and connected between the positive output terminal 23 and the negative output terminal 24 of the driving power supply 20 to The two input terminals 21 and 22 of the source 20 are respectively electrically connected to the emergency power supply 10 and are powered. The driving power supply 20 can power the LED lamp beads 30 with a stable voltage or current at the positive output terminal 23 and the negative output terminal 24. In the present invention, the driving power supply 20 and the LED lamp beads 30 can be LED lamps that are arranged as a whole, or they can be separately arranged lighting systems, wherein the emergency power supply 10 is adapted to different types of driving power supplies 20, which is conducive to simplifying the upgrade and modification of emergency lamps.

[0054] Furthermore, the emergency power supply 10 has a mode selection circuit 12 and is configured to have a constant voltage output mode and a constant power output mode, wherein the emergency power supply 10 switches to the corresponding output mode of the emergency power supply state based on the mode selection circuit 12, wherein in the constant voltage output mode, the emergency power supply 10 outputs electric energy to the driving power supply 20 at the two output ends 101 and 102 based on the set voltage, wherein in the constant power module, the emergency power supply 10 adjusts the electric energy output to the driving power supply 20 at the two output ends 101 and 102 based on the matching of the output voltage and the current.

[0055] Specifically, in this embodiment of the present invention, the mode selection circuit 12 is implemented as a dip switch to facilitate user operation to select between the constant voltage output mode and the constant power output mode.

[0056] It is worth mentioning that, in some embodiments, the mode selection circuit 12 may also be implemented as a jumper, or other circuits that implement sampling through high and low levels.

[0057] It is worth mentioning that corresponding to Figure 4 , wherein the emergency power supply 10 includes a 0-10V dimming circuit, wherein the emergency power supply 10 is in the constant voltage output mode, and the emergency power supply 10 adjusts the power of the driving power supply 20 based on the 0-10V dimming circuit to reduce power consumption.

[0058] In particular, the emergency power supply 10 can switch to different output modes, and thus can be adapted to different types of the driving power supplies 20. For example, corresponding to the existing lamp tube or bulb in which the driving power supply 20 and the LED lamp beads 30 are integrally arranged, the emergency power supply 10 can be switched to the constant power output mode to avoid the defect that the lamp tube and the bulb cannot be connected to the 0-10V dimming circuit and cannot be transformed into an emergency lamp due to their small size. The emergency power supply 10 can be switched to the constant voltage output mode, and thus can also be widely compatible with UFO lamps, LED downlights, etc., and has high compatibility and is generally applicable to LED lamps on the market.

[0059] That is to say, the emergency power supply 10 can be adapted to most of the driving power supplies 20 currently on the market, and thus ordinary lamps can be transformed into emergency lamps by respectively connecting the two input terminals 21 and 22 of the driving power supply 20 to the two output terminals 101 and 102 of the emergency power supply 10, thereby enriching the diversity of emergency lamps based on the selection of different lamps, and correspondingly improving the adaptability of the emergency power supply system 100 to different scenarios and application requirements.

[0060] Moreover, ordinary lamps can be transformed into emergency lamps by respectively connecting the two input terminals 21 and 22 of the driving power supply 20 to the two output terminals 101 and 102 of the emergency power supply 10, and different lamps can be adapted based on the different output modes provided by the emergency power supply 10, so that common small LED lamps such as bulb lamps and T8 tubes can be selected to meet the small volume requirements of emergency lamps, and thus have a wider range of application scenarios.

[0061] And the emergency power supply 10 detects its input voltage based on the voltage detection circuit 11, and is able to output a voltage within a voltage range of 20V to 400V at the output end, so that different driving power supplies 20 can be powered at a suitable voltage, thereby improving the versatility of the emergency power supply 10.

[0062] It is worth mentioning that the emergency power supply 10 is suitable for matching existing lamps, so that the two input ends 21 and 22 of the driving power supply 20 can be connected to the two output ends 101 and 102 of the emergency power supply 10 respectively, so that ordinary lamps can be transformed into emergency lamps, which is suitable for the transformation of ordinary lamps.

[0063] In particular, the emergency power supply 10 can be adapted to various types of lamps, so that ordinary lamps can be transformed into emergency lamps by respectively connecting the two input ends 21 and 22 of the driving power supply 20 to the two output ends 101 and 102 of the emergency power supply 10. Therefore, it is suitable for repairing emergency lamps by independently replacing the lamps corresponding to the LED lamp beads 30 or the driving power supply 20, which correspondingly reduces the maintenance cost of the emergency power supply system 100.

[0064] Further, refer to Figure 5 and Figure 6 , the wiring of the driving power system 100 in the normal power supply state and the emergency power supply state are respectively illustrated, wherein the emergency power supply 10 includes an energy storage unit 13 and an inverter circuit 14, wherein the inverter circuit 14 is electrically connected to the energy storage unit 13, wherein in the normal power supply state, the energy storage unit 13 charges and stores energy, wherein in the emergency power supply state, the energy storage unit 13 outputs electric energy to the inverter circuit 14, wherein the voltage detection circuit 11 and the mode selection circuit 12 are electrically connected to the inverter circuit 14, so as to detect the input voltage of the emergency power supply 100 in the normal power supply state based on the voltage detection circuit 11, match the output voltage of the inverter circuit 14 in the emergency power supply state, and switch the output mode of the inverter circuit 14 when powered by the energy storage unit 13 based on the selection of the mode selection circuit 12.
