Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically to an LED driver device that works in conjunction with an emergency module. Background Technology

[0002] An LED driver device for use with an emergency module is a drive device capable of switching the power supply from mains power to a backup power supply. In the event of a mains power outage, it can switch to battery power to allow the LED lighting equipment to continue operating. In the prior art, a Chinese invention disclosure document (publication number: CN119146409A) discloses an LED lamp that "includes a light source, a drive module for driving the light source, and a power module for supplying power to the drive module. The power module is electrically connected to the drive module. The drive module has a first plug-in terminal, which is electrically connected to the light source. The LED lamp also includes a connector and..." The emergency module has a connector with a second plug-in terminal and an emergency module with a third plug-in terminal. The connector and the emergency module can be selectively operated, thereby enabling the LED lamp to have the following two operating states: In the first operating state, the second plug-in terminal of the connector is engaged with the first plug-in terminal of the driver module, and the connector enables the driver module to conduct electricity with the light source; In the second operating state, the third plug-in terminal of the emergency module is engaged with the first plug-in terminal of the driver module, and the emergency module enables the light source to conduct electricity, so as to drive the light source to work through the emergency module.

[0003] In the above scheme, the switching between AC power supply and battery power supply is achieved by selectively connecting the second and third plug terminals to the first plug terminal. However, this design requires two steps of unplugging and plugging in each time to switch the circuit, regardless of whether AC power supply or battery power supply is used, which is inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to develop an LED driver device that works in conjunction with an emergency module, in order to solve the problem that the switching between the power supply circuit and the emergency circuit in existing LED driver devices is not convenient enough, and to improve the ease of use.

[0005] This utility model provides an LED driver device for use with an emergency module, comprising the following structure:

[0006] The driving module includes an LED light source circuit, a first plug-in part, an opening and closing valve, and a power supply circuit powered by mains electricity. The LED light source circuit includes a first light source circuit and a second light source circuit. The opening and closing valve has a conducting state that connects the power supply circuit and the first light source circuit, and a blocking state that disconnects the power supply circuit from the first light source circuit. The second light source circuit is electrically connected to the first plug-in part.

[0007] An emergency module, detachably connected to the drive module, includes a battery module, a second connector, and a pusher, wherein the battery module and the second connector are electrically connected.

[0008] When the emergency module is separated from the drive module, the opening and closing valve is in the conducting state, and the first plug-in part and the second plug-in part are separated.

[0009] When the emergency module is connected to the drive module, the first plug-in part and the second plug-in part are plugged in to make the second light source circuit electrically connected to the battery module. At the same time, the pusher drives the opening and closing valve to switch from the conducting state to the blocking state.

[0010] The beneficial effects of the above technical solution are as follows: When the drive module is used alone, the opening and closing valve is in the conducting state, which connects the power supply circuit and the first light source circuit, thereby enabling the power supply to power the LED light source; when the emergency module is connected to the drive module, the pusher drives the opening and closing valve to switch from the conducting state to the blocking state, which disconnects the power supply circuit from the first light source circuit. At the same time, the first plug and the second plug engage, which electrically connects the second light source circuit to the battery module, and the battery powers the LED light source; compared with the circuit switching achieved by switching two plug components, this solution achieves the disconnection of the LED light's power supply circuit (the pusher drives the opening and closing valve to switch states) and the connection of the emergency circuit (the first plug and the second plug engage) with a single plug action. The structure is ingenious and easy to use.

[0011] In one possible implementation, the opening / closing valve includes a conductive contact. When the opening / closing valve is in the conducting state, the conductive contact is located in the conducting position that connects the power supply circuit and the first light source circuit. When the opening / closing valve is in the blocking state, the conductive contact is located in the blocking position that disconnects the power supply circuit from the first light source circuit. When the emergency module is separated from the drive module, the conductive contact is positioned in the conducting position. When the emergency module is connected to the drive module, the pusher pushes the conductive contact from the conducting position to the blocking position.

[0012] When the drive module is used alone, the conductive contact is positioned in the on position; when the emergency module is connected to the drive module, the pusher pushes the conductive contact from the on position to the off position, disconnecting the power circuit from the first light source circuit. At the same time, the first plug and the second plug engage to electrically connect the second light source circuit to the battery module, and the battery supplies power to the LED light source.

[0013] In one possible implementation, the pusher includes an insulating part, and the opening and closing valve includes two conductive contacts arranged in pairs, the two conductive contacts being respectively connected to a power supply circuit and a first light source circuit;

[0014] When the valve is in the open state, the two conductive contacts are in contact (open position); when the valve is in the closed state, the insulating part of the pusher is inserted between the two conductive contacts to separate them (closed position).

[0015] In another possible implementation, the opening and closing valve includes a first pin and a second pin that are separated from each other. The first pin is connected to a power supply circuit, and the second pin is connected to a first light source circuit. When the conductive contact is in the conducting position, the conductive contact is in contact with both the first pin and the second pin. When the conductive contact is in the blocking position, the conductive contact is separated from the first pin and / or the second pin.

[0016] In one possible implementation, the opening and closing valve includes a first opening and closing valve and a second opening and closing valve. The first opening and closing valve is used to control the on and off of the circuit between the input terminal and the output terminal of the power circuit. The second opening and closing valve is used to control the on and off of the circuit between the input terminal and the output terminal of the first light source circuit. The emergency module is provided with a first pusher and a second pusher that cooperate with the first opening and closing valve and the second opening and closing valve, respectively.

[0017] In one possible implementation, the opening and closing valve further includes a valve housing that accommodates the conductive contact piece, the valve housing having a pressure hole for inserting a pusher; the position of the conductive contact piece corresponds to the pressure hole, so that after the pusher is inserted into the pressure hole, it pushes the conductive contact piece to move, and the pressure hole guides the pusher.

[0018] In one possible implementation, the opening / closing valve includes a reset assembly that cooperates with the conductive contact. The reset assembly includes an elastic element. When the conductive contact is in the on position, the elastic element limits the conductive contact to maintain contact with the first pin and the second pin. When the conductive contact is in the off position, the pusher pushes against the conductive contact, thereby compressing or stretching the elastic element, so that the elastic element has elastic potential energy to drive the conductive contact back to the on position. This facilitates the reset of the conductive contact after the emergency module is disassembled, allowing the power circuit to supply power to the light source again, and facilitating multiple switching between the power circuit and the battery circuit.

[0019] In one possible implementation, the reset assembly is located below the conductive contact; the opening and closing valve further includes a valve housing that accommodates the conductive contact, the valve housing having a pressure hole for inserting a pusher, when the conductive contact is in the conducting position, the conductive contact is in contact with the lower surfaces of the first pin and the second pin, the pressure hole is located above the conductive contact, causing the pusher to push the conductive contact from top to bottom and compress the elastic element.

[0020] Specifically, the reset assembly includes a pressure block disposed between the conductive contact and the elastic element. The conductive contact is positioned on the pressure block, and the lower end of the pressure block has a positioning post. The elastic element is a spring, one end of which is sleeved on the positioning post, and the other end is positioned and engaged with the inner wall of the valve body.

[0021] In one possible implementation, the first mating end of the drive module and the second mating end of the emergency module are detachably connected. The opening and closing valve and the first plug-in part are both disposed on the upper surface of the first mating end, and the pusher and the second plug-in part are both disposed on the lower surface of the second mating end. The first mating end and the second mating end are mated in a stepped manner. When the drive module is connected to the emergency module, there is a smooth transition between the outer surface of the drive module and the outer surface of the emergency module, making the overall device more aesthetically pleasing.

[0022] In one possible implementation, the emergency module and the drive module are positioned by a slot and a locking block. When the locking block is inserted into the slot, the pusher drives the opening and closing valve to switch from a conducting state to a blocking state. The first plug-in part and the second plug-in part are plugged in and engaged, and the locking and positioning are further enhanced on the basis of the plugging and engagement, so that the connection between the emergency module and the drive module is more stable.

[0040] To make the objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments are described in detail below with reference to the accompanying drawings.

[0041] like Figures 1 to 12 As shown, this embodiment provides an LED driver device that works in conjunction with an emergency module. It includes a detachably connected driver module 1 and an emergency module 3, with the specific configuration as follows:

[0042] The driving module 1 includes a power terminal 11, an LED light source terminal 12, an LED light source circuit, a first plug-in part 13, an opening and closing valve 2, and a power supply circuit powered by mains electricity. The LED light source circuit includes a first light source circuit and a second light source circuit. The opening and closing valve 2 has a conducting state that connects the power supply circuit and the first light source circuit, and a blocking state that disconnects the power supply circuit from the first light source circuit. The second light source circuit is electrically connected to the first plug-in part 13.

[0043] Emergency module 3, which is detachably connected to drive module 1, includes battery module 31, second plug-in part 32, and pusher 33, wherein battery module 31 and second plug-in part 32 are electrically connected.

[0044] When the emergency module 3 is separated from the drive module 1, the opening and closing valve 2 is in the conducting state, and the first plug-in part 13 and the second plug-in part 32 are separated.

[0045] When the emergency module 3 is connected to the drive module 1, the first plug-in part 13 and the second plug-in part 32 are plugged in to make the second light source circuit electrically connected to the battery module 31. At the same time, the pusher 33 drives the opening and closing valve 2 to switch from the conducting state to the blocking state.

[0046] In one embodiment, the opening / closing valve 2 includes a conductive contact 21. When the opening / closing valve 2 is in the conducting state, the conductive contact 21 is located in the conducting position that connects the power supply circuit and the first light source circuit. When the opening / closing valve 2 is in the blocking state, the conductive contact 21 is located in the blocking position that disconnects the power supply circuit from the first light source circuit. When the emergency module 3 is separated from the drive module 1, the conductive contact 21 is positioned in the conducting position. When the emergency module 3 is connected to the drive module 1, the pusher 33 pushes the conductive contact 21 from the conducting position to the blocking position.

[0047] When the drive module is used alone, the conductive contact is positioned in the on position, which connects the power supply circuit and the first light source circuit, thereby enabling the power supply to power the light source. When the emergency module is connected to the drive module, the conductive contact moves from the on position to the off position, which disconnects the power supply circuit from the first light source circuit. At the same time, the first plug and the second plug engage, which electrically connects the second light source circuit to the battery module, and the battery powers the light source.

[0048] In one embodiment, such as Figure 7 , Figure 8 As shown, the pusher 33 includes an insulating part, and the opening and closing valve 2 includes two conductive contacts 21 arranged in pairs. The two conductive contacts 21 are respectively connected to the power supply circuit and the first light source circuit.

[0049] When the valve 2 is in the conducting state, the two conductive contacts 21 are in contact (conducting position). In this embodiment, a bend is provided on the conductive contacts so that the bend is in contact.

[0050] When the opening and closing valve 2 is in the blocking state, the insulating part of the pusher 33 is inserted between the two conductive contacts 21 to separate the bent parts of the two conductive contacts 21 (blocking position).

[0051] In another embodiment, the opening and closing valve 2 includes a first pin 231 and a second pin 232 that are separated from each other. The first pin 231 is connected to a power supply circuit, and the second pin 232 is connected to a first light source circuit. When the conductive contact 21 is in the conducting position, the conductive contact 21 is in contact with both the first pin 231 and the second pin 232. When the conductive contact 21 is in the blocking position, the conductive contact 21 is separated from the first pin 231 and / or the second pin 232.

[0052] In one embodiment, such as Figure 2 , Figure 3 , Figure 6As shown, the opening and closing valve 2 includes a first opening and closing valve and a second opening and closing valve. The first opening and closing valve is used to control the on and off of the circuit between the input terminal and the output terminal of the power circuit. The second opening and closing valve is used to control the on and off of the circuit between the input terminal and the output terminal of the first light source circuit. The emergency module 3 is provided with a first pusher and a second pusher that cooperate with the first opening and closing valve and the second opening and closing valve, respectively.

[0053] Specifically, such as Figure 13 As shown, the first pin of the first opening and closing valve is connected to the first connection terminal SL1 of the drive module, and the second pin of the first opening and closing valve is connected to the second connection terminal Lout1 of the drive module.

[0054] The first pin of the second opening and closing valve is connected to the third connection terminal In1+ of the drive module, and the second pin of the second opening and closing valve is connected to the fourth connection terminal LED1+ of the drive module.

[0055] Both the first and second opening / closing valves are configured to be in the conducting state, where the LED light is powered by the mains electricity through the driving module; and in the blocking state, the LED light is powered by the battery module of the emergency module.

[0056] In one embodiment, reference is made to... Figures 4 to 6 The opening and closing valve 2 also includes a valve housing 22 that accommodates the conductive contact 21. The valve housing 22 is provided with a pressure hole 201 for the insertion of the pusher 33. The position of the conductive contact 21 corresponds to the pressure hole 201, so that the pusher 33 pushes the conductive contact 21 to move after being inserted into the pressure hole 201.

[0057] In one embodiment, the conductive contact 21 is provided with a reset component, the reset component including an elastic element 213; when the conductive contact 21 is in the conducting position, the elastic element 213 limits the conductive contact 21 so that the conductive contact 21 contacts and engages with the first pin 231 and the second pin 232; when the conductive contact 21 is in the blocking position, the pusher 33 pushes the conductive contact 21 and compresses the elastic element 213, so that the elastic element 213 has elastic potential energy to drive the conductive contact 21 back to the conducting position.

[0058] In one embodiment, the conductive contact 21 is located below the first pin 231 and the second pin 232, and the reset component is located below the conductive contact 21. The opening and closing valve 2 further includes a valve housing 22 that accommodates the conductive contact 21. The valve housing 22 is provided with a pressing hole 201 for inserting a pusher 33. The pressing hole 201 is located above the conductive contact 21, so that the pusher 33 pushes the conductive contact 21 from top to bottom. When the conductive contact 21 is in the conducting position, the conductive contact 21 is in contact with the lower surface of the first pin 231 and the second pin 232.

[0059] Furthermore, the reset assembly also includes a pressing block 211 disposed between the conductive contact 21 and the elastic member 213. The conductive contact 21 is positioned on the pressing block 211, and the lower end of the pressing block 211 has a positioning post 212. The elastic member 213 is a spring, one end of which is sleeved on the positioning post 212, and the other end is positioned and engaged with the inner wall of the valve housing 22.

[0060] Reference Figure 4 and Figure 11 The lower ends of the first pin 231 and the second pin 232 extend out of the valve housing 22 and are inserted into the mounting through hole 161 on the mounting plate 16 of the drive module 1 to connect with the circuit.

[0061] In one embodiment, the first mating end 101 of the drive module 1 is detachably connected to the second mating end 301 of the emergency module 3. The opening and closing valve 2 and the first plug-in part 13 are both disposed on the upper surface of the first mating end 101, and the pusher 33 and the second plug-in part 32 are both disposed on the lower surface of the second mating end 301. The first mating end 101 and the second mating end 301 are mated in a stepped manner. When the drive module 1 is connected to the emergency module 3, there is a smooth transition between the outer surface of the drive module 1 and the outer surface of the emergency module 3, making the product appearance more aesthetically pleasing.

[0062] Furthermore, in the above embodiments, the emergency module 3 and the drive module 1 are positioned by snapping together through the slot 14 and the snap-fit ​​block 34. The emergency module 3 and the drive module 1 are detachably connected to the same fixed base plate 4. The fixed base plate 4 is respectively provided with a first slot 41 that engages with the drive module 1 and a second slot 42 that engages with the emergency module 3. When the snap-fit ​​block 34 is snapped into the slot 14, the pusher 33 drives the opening and closing valve 2 to switch from the conducting state to the blocking state, and the first insertion part 13 and the second insertion part 32 are inserted and engaged.

[0063] In this embodiment, the slot 14 is disposed on the side wall of the drive module 1, and the upper end of the slot 14 is provided with a toggle groove 141 extending to the top of the drive module 1. The snap-fit ​​block 34 is U-shaped and includes a connecting part connected to the side of the emergency module 3 and a snap-fit ​​part that snaps into the slot 14. There is a slot between the connecting part and the snap-fit ​​part to allow for deformation space between the snap-fit ​​part and the connecting part. The upper end of the snap-fit ​​part is provided with a toggle block 341, and the toggle block 341 is limited to the toggle groove 141.

[0064] During disassembly, the toggle block 341 is moved to move the latching part closer to the connecting part, so that the latching part is disengaged from the slot, thereby allowing the drive module 1 to be separated from the emergency module 3.

[0065] Furthermore, the width of the actuating groove 141 is smaller than the width of the slot 14, so that when the actuating block 341 is confined within the actuating groove 141, the locking part is circumferentially confined within the slot 14; during installation, the actuating block 341 is actuated to drive the locking part to move towards the connecting part, first causing the locking part to enter the slot 14, and then the actuating block 341 is aligned with the actuating groove 141, so that the actuating block 341 is confined within the actuating groove 141.

[0066] The first mating end 101 is also provided with a positioning block 142. When the snap-fit ​​block 34 is snapped into the slot 14, the second side wall 342 of the second mating end 301 is limited to the positioning block 142 and the first side wall of the drive module 1.

[0067] Furthermore, the driving module 1 is also provided with an adjustment module 15, which is used to adjust the color temperature and power of the LED lamp. Regarding the adjustment of the color temperature and power of the LED lamp, there are many ways to set the adjustment circuit in the art, and no limitation is made in this solution.
