Description

Technical Field

[0001] This utility model relates to the technical field of lighting, and in particular to a dimmable emergency light. Background Technology

[0002] The prior application CN222142963U, "A Dial-Switch Lighting Device," discloses a lighting device capable of dimming via a dial switch. The device includes a lamp body, a lampshade, a light source board, a circuit board, a dial switch, and a dial switch component. The lamp body has a cavity and a light-emitting port communicating with the cavity. The light source board is located within the cavity, and the lampshade is mounted on the light-emitting port. LED beads facing the lampshade are located on the front side of the light source board. The circuit board is located on the front side of the light source board, and the light source board has mounting holes. The dial switch is located on the back side of the light source board and is connected to the circuit board through the mounting holes. The dial switch component is movably connected to the side wall of the lamp body and is positioned below the light source board. The dial switch component and the dial switch are connected.

[0003] Although the above structure can be used to adjust the brightness of the light by toggling the DIP switch, the circuit board is located on the front of the light source board, which occupies part of the lighting area of ​​the light source board, thus having a certain negative impact on the light emission of the light source board.

[0004] In addition, because emergency lights need to integrate more functional modules on their circuit boards, they are larger than those of conventional lights, which further exacerbates the negative impact of light blocking. Utility Model Content

[0005] The present invention aims to provide a dimming emergency light that integrates a dial switch dimming function within a limited space.

[0006] A dimming emergency light according to a first aspect embodiment of the present invention includes:

[0007] The lamp body includes a lamp head, a housing, and a lamp shade, which are connected in sequence to form an assembly chamber. The housing has a dial hole on its side.

[0008] A circuit board is located in the assembly chamber. The circuit board is connected to a DIP switch. The direction of the DIP switch corresponds to the setting direction of the DIP hole. The circuit board is provided with a connection terminal extending towards the lampshade.

[0011] A storage battery is located in the assembly chamber and is electrically connected to the lamp holder and the circuit board.

[0012] The dimming emergency light according to the embodiments of this utility model has at least the following beneficial effects: Since the light source board is located between the circuit board and the lamp cover, it provides sufficient space for the circuit board to integrate functional modules that conventional lamps do not have, such as charging management modules, power switching modules, and control and detection modules. Since the circuit board and the light source board are electrically connected through connecting terminals and connecting heads, the front of the light source board is not blocked by the circuit board. Therefore, the light source board can be equipped with more LEDs to meet the lighting needs during emergency power outages. Furthermore, the circuit board and the light source board are independently designed, eliminating the need to re-mold for their assembly design, thus saving a significant amount of development costs. On the other hand, the dial module, composed of a dial element and a dial switch, can be set in the inherent area between the light source board and the circuit board to save space in the assembly room. At this time, the user can adjust the light source of the emergency light by toggling the dial element to switch the position of the dial switch, thereby meeting different lighting needs of the user.

[0014] According to some embodiments of the present invention, the outer casing is provided with a lift position above the circuit board, and the light source board is pressed into the lift position by interference fit, so as to eliminate the need for screw connection of the light source board and facilitate assembly.

[0015] According to some embodiments of the present invention, in order to further compress the space of the assembly room, the circuit board is provided with a clearance space to avoid the battery, so that the battery can pass through the clearance space and extend to the top of the circuit board.

[0016] According to some embodiments of this utility model, the DIP switch has two clamping arms, and the DIP switch has a movable DIP handle located between the two clamping arms. When either clamping arm abuts against the DIP handle and moves it in one direction, the internal circuit of the DIP switch is adjusted accordingly, thereby achieving dimming of the emergency light.

[0017] According to some embodiments of the present invention, in order to simulate the effect of a human hand turning the dial lever, both of the clamping arms are provided with contacts that abut against the dial lever.

[0018] According to some embodiments of the present invention, the dial component is provided with a dial buckle, which passes through the dial hole and is engaged with the edge of the dial hole to prevent the dial component from falling out of the dial hole, thereby realizing a limited sliding connection between the dial component and the dial hole.

[0019] According to some embodiments of the present invention, the outer side of the housing is provided with a recess, the dial hole is disposed in the recess, and the dial component slides in the recess so that the dial component and the outer side of the housing are kept as flush as possible.

[0033] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0034] like Figures 1 to 3As shown, according to a first aspect embodiment of the present invention, a dimmable emergency light includes a lamp body 10, a circuit board 400, a light source board 500, a DIP switch 600, and a battery 700. The lamp body 10 serves as the main body of the emergency light and includes a lamp head 100, a housing 200, and a lamp shade 300. The lamp head 100 may be a conductive metal component for electrical connection with a lamp holder (not shown in the figures). The housing 200 may be an insulating plastic component, with an external thread section 210 at its lower end for threaded connection with the lamp head 100, and an internal thread section 220 at its upper end for threaded connection with the lamp shade 300. The lamp shade 300 may be an insulating plastic component, and its material is translucent. The lamp head 100, housing 200, and lamp shade 300 are sequentially threaded together to form the lamp body 10 having an assembly chamber 11. The circuit board 400, light source board 500, and battery 700 are all disposed within the assembly chamber 11.

[0035] In this embodiment, the lamp body 10 can be pear-shaped, with the largest external dimension at the location of the lampshade 300 and the smallest external dimension at the location of the lamp head 100. The external dimension of the outer casing 200 gradually increases from the lamp head 100 towards the lampshade 300. Since the lamp body 10 is narrower near the lamp head 100, this location is not suitable for placing the circuit board 400. Therefore, the assembly chamber 11 is used to place the battery 700, such as an 18650 battery, which is a long cylindrical battery. The battery 700 is electrically connected to both the lamp head 100 and the circuit board 400.

[0036] When the lamp holder is energized, the mains power flows sequentially through the lamp holder, lamp head 100, and battery 700, charging the battery 700. During this time, under the control of the power switching module, the battery 700 does not discharge the light source board 500, causing the LEDs on the light source board 500 to not emit light. When the lamp holder is de-energized, i.e., during a power outage, the battery 700, under the control of the power switching module, discharges the light source board 500, causing the LEDs on the light source board 500 to emit light, thus providing emergency lighting during a power outage. After the lamp holder is energized again, the mains power continues to charge the battery 700, but the battery 700, under the control of the power switching module, does not discharge the light source board 500, causing the LEDs on the light source board 500 to not emit light.

[0037] Furthermore, since the circuit board 400 integrates many functional modules, but its substrate is relatively fragile, it is necessary to limit the position of the circuit board 400 within the assembly chamber 11 to prevent it from colliding with internal components due to external vibrations. To this end, the assembly chamber 11 is provided with multiple connecting parts 230, which can be studs. Correspondingly, the circuit board 400 has mounting holes 430 that correspond one-to-one with the positions of the connecting parts 230. The circuit board 400 is fixedly connected by screws passing through the mounting holes 430 and threaded onto the studs. Since the battery 700 is located below the circuit board 400, it is generally placed horizontally, in which case the circuit board 400 is located in the center of the assembly chamber 11.

[0038] The integrated functional modules on circuit board 400 include, but are not limited to, an AC / DC conversion module, a charging management module, a battery module, a power switching module, a control and detection module, a light source driver module, and a protection circuit module. The AC / DC conversion module converts 220V AC power to low-voltage DC power, such as 12V DC or 24V DC. The charging management module controls the battery charging process, preventing overcharging, over-discharging, and short circuits. It employs a constant current-constant voltage charging mode, first using a constant current for rapid charging, then using a constant voltage for float charging to protect the battery. The power switching module detects the mains power status and automatically switches to battery power when the mains power fails, with seamless switching achieved by a MOSFET. The control and detection module monitors parameters such as mains power status, battery voltage, and load current, and controls the switching logic and status indication of the emergency light. The light source driver module drives LED beads or other light sources, adjusting the brightness and color of the light. The protection circuit module has overvoltage protection, overcurrent protection and temperature protection. Overvoltage protection can prevent the circuit from being damaged by excessive mains voltage. Overcurrent protection can limit the current during short circuit or overload. Temperature protection prevents overheating through thermistors or temperature switches.

[0039] Because the emergency light circuit board 400 needs to integrate more functional modules, it is more complex and larger than the circuit board 400 of a conventional light fixture, and cannot be assembled with a conventional light source board 500.

[0040] In some embodiments of this utility model, to further compress the space of the assembly chamber 11, the circuit board 400 is provided with a clearance 410 to avoid the battery 700. This clearance 410 is located in the middle of the circuit board 400, allowing the battery 700 to pass through the clearance 410 and extend above the circuit board 400. During assembly, the battery 700 utilizes a portion of the space on the circuit board 400, thus shortening the overall length of the emergency light to meet the compact design requirements. Of course, the position of the battery 700 also needs to be limited by positioning components (not shown in the figures), such as retaining rings, to prevent the battery 700 from being in a movable state within the assembly chamber 11, which would increase the risk of collision between the battery 700 and other components.

[0041] In addition, the inner wall of the housing 200 is provided with a lifting position 240 for mounting the light source board 500. The lifting position 240 is a slot used to define the position of the light source board 500. The lifting position 240 is located above the circuit board 400. Correspondingly, the edge of the light source board 500 is pressed into the lifting position 240 by interference fit, so as to define the light source board 500 in a designated position without the use of screws. At this time, the light source board 500 is located above the circuit board 400, and the two are spaced apart, giving the circuit board 400 sufficient space for installation.

[0042] Since the light source board 500 is a consumable part, multiple flat slots 510 are provided along its edge to facilitate replacement. The distance from the flat slot 510 to the center of the light source board 500 is less than the radius of the light source board 500, and each flat slot 510 is provided with a force-bearing protrusion 511. During assembly, neither the force-bearing protrusion 511 nor the flat slot 510 is engaged in the lifting position 240. During the disassembly of the light source board 500, the maintenance personnel use a special tool to reach into the flat slot 510 and pull upward on the force-bearing protrusion 511 to remove the light source board 500 from the lifting position 240.

[0043] like Figure 3 and Figure 5As shown, to achieve electrical connection between circuit board 400 and light source board 500, circuit board 400 is provided with connection terminal 420 extending towards light source board 500, and connection terminal 420 is provided with multiple pins 421. Correspondingly, light source board 500 is provided with connection head 520 for electrical connection with connection terminal 420, connection head 520 is provided with socket 521 corresponding to pins 421, each socket 521 is provided with spring contact 522, and each pin 421 passes through the corresponding socket 521 and abuts against spring contact 522. When electrical connection is required, with circuit board 400 fixed, connection head 520 of light source board 500 is aligned with connection terminal 420 of circuit board 400, and then light source board 500 is moved downward so that multiple pins 421 pass through the corresponding socket 521. Since each socket 521 is provided with spring contact 522, each pin 421 can abut against the corresponding spring contact 522 to prevent open circuit. The electrical connection process is simple and effective, requiring no tools, making it ideal for the assembly and disassembly of the 500 light source board.

[0044] As is well known, the front of the light source board 500 is provided with multiple LED beads (not shown in the attached diagram) facing the lamp cover 300. These can be LED beads. This utility model does not limit the number of LED beads or their distribution. Manufacturers can arrange the multiple LED beads reasonably according to customer needs. Since the light source board 500 can only be powered on one side, that is, the side with the LED beads is powered, the pins of the connecting terminal 520 need to be soldered to the front of the light source board 500.

[0045] like Figures 1 to 4 As shown, to achieve dimming of the LED beads, a DIP switch hole 250 is provided on the side of the housing 200. A DIP switch component 600 is slidably connected to the DIP switch hole 250. The DIP switch piece 610 of the DIP switch component 600 is located outside the DIP switch hole 250. The DIP switch component 600 has a DIP switch clip 620 extending to the assembly chamber 11. The DIP switch clip 620 has two clamping arms 621, and a reinforcing rib 630 is connected between the two clamping arms 621 to prevent the clamping arms 621 from being bent. Correspondingly, a DIP switch 800 facing the DIP switch hole 250 is connected to the circuit board 400. The DIP switch 800 is used to control the light source driving module. The DIP switch 800 has a toggleable DIP switch handle 810, which is located between the two clamping arms 621.

[0046] The DIP switch 800 has multiple positions, each corresponding to a different internal circuit. Switching between these positions is achieved by moving the DIP lever 810. The number of positions on the DIP switch 800 corresponds to the number of movable positions on the DIP lever 810. When any of the clamping arms 621 abuts against the DIP lever 810 and moves it in one direction, the internal circuitry of the DIP switch 800 is adjusted accordingly. The circuit board 400 feeds this control signal back to the light source driver module, which then adjusts the brightness of the LEDs based on the different positions.

[0047] In some embodiments of this utility model, in order to better operate the dial switch 600, the outer surface of the dial switch 610 is provided with anti-slip strips 611. The anti-slip strips 611 are arranged in the vertical direction, and there are two anti-slip strips 611. An installation direction mark 612 is provided between the two anti-slip strips 611. The installation direction mark 612 can be an arrow to indicate the correct installation direction of the dial switch 600 during assembly.

[0048] It should be noted that the direction of the dial lever 810 must match the setting direction of the dial hole 250. If the dial hole 250 is set horizontally along the outer casing 200, then the direction of the dial lever 810 must also be set horizontally. Otherwise, the position of the dial lever 810 cannot be moved by sliding the dial piece 610.

[0049] Furthermore, to simulate the effect of a human hand operating the DIP switch 810, both clamping arms 621 are equipped with contacts 622 that abut against the DIP switch 810. When the user slides the DIP switch 610, the two clamping arms 621 of the DIP switch clamp 620 also slide accordingly. However, the clamping arms 621 can only operate the DIP switch 810 through the contacts 622 to simulate the operation of a human hand. If there were no contacts 622, the two clamping arms 621 would need to be in contact with the DIP switch 810. This design does not provide sufficient leeway for the rotation of the DIP switch 810, making it very easy to break the DIP switch 810.

[0050] In other embodiments, the light source driving module can not only adjust the brightness of the emergency light, but also adjust the color of the emergency light. In this case, the light source board 500 is provided with multiple LED beads of different colors so as to emit different colors of light under the control of the light source driving module.

[0051] With the above structure, since the light source board 500 is located between the circuit board 400 and the lampshade 300, the circuit board 400 has sufficient space to integrate functional modules not found in conventional lamps, such as charging management modules, power switching modules, and control and detection modules. Because the circuit board 400 and the light source board 500 are electrically connected via connecting terminals 420 and 520, the front of the light source board 500 is not obstructed by the circuit board 400. Therefore, the light source board 500 can accommodate more LEDs to meet lighting needs during emergency power outages. Furthermore, since the circuit board 400 and the light source board 500 are independently designed, there is no need to create new molds for their assembly, saving significant development costs.

[0052] On the other hand, the DIP module, consisting of DIP switch 600 and DIP switch 800, can be set in the inherent area between the light source board 500 and the circuit board 400 to save space in the assembly chamber 11. At this time, the user can adjust the light source of the emergency light by moving the DIP switch 600 to the position of the DIP switch 800, thereby meeting the user's different lighting needs.

[0053] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the dial component 600 is provided with two dial buckles 640. The two dial buckles 640 are symmetrically arranged on the upper and lower sides of the dial clip 620. The two dial buckles 640 pass through the dial hole 250 and are engaged with the upper and lower edges of the dial hole 250 to prevent the dial component 600 from falling out of the dial hole 250, thereby realizing the limiting sliding connection between the dial component 600 and the dial hole 250.

[0054] like Figure 1 and Figure 2 As shown, further, the outer surface of the housing 200 is provided with a recess 251. The recess 251 is not directly connected to the assembly chamber 11. The DIP switch hole 250 is located in the middle of the recess 251. The size of the recess 251 is not only larger than the size of the DIP switch hole 250, but also larger than the size of the DIP switch piece 610, so that the DIP switch piece 610 can slide back and forth in the recess 251. Since the recess 251 has a certain depth, the DIP switch piece 600 can be kept as flush as possible with the outer surface of the housing 200 to improve the appearance of the emergency light.

[0055] In some embodiments of this utility model, in order to enhance the heat dissipation effect, the side of the housing 200 is provided with a plurality of heat dissipation holes 260, all of which are connected to the assembly chamber 11. Specifically, the heat dissipation holes 260 are located between the circuit board 400 and the light source board 500, and are mainly used to dissipate heat from the functional modules on the circuit board 400.

[0056] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
