Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a firefighter lighting lamp with power display function. Background Technology

[0002] Most existing firefighter lighting systems use a single LED or multiple LEDs simultaneously for illumination, lacking features such as floodlight modes and power level displays. This fails to adequately meet user needs. Furthermore, their waterproofing is incomplete and inadequate, affecting their lifespan. Therefore, designing a firefighter lighting system capable of multiple illumination modes and power level displays has become an urgent technical challenge. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a firefighter lighting lamp with power display function to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] According to one aspect of this utility model, a firefighter lighting lamp with a power display function is designed, comprising: a lamp head, a lamp body, and a rear cover. The lamp head includes a lamp head shell and, from left to right, a lens, a reflector cup within a light-transmitting element, a first main board, a mounting base, and a first conductive plate electrically connected to the first main board. A first sealing ring is provided between the lens and the lamp head shell for sealing contact between the two. A main LED bead located in a through hole on the reflector cup is connected to the center of the first main board. A plurality of floodlight LED beads corresponding to the light-transmitting element are connected around the edge of the first main board. The lamp head shell and the lamp body are threadedly connected, and a second sealing ring is provided between them. The first conductive plate inside the lamp body... A first inclined surface on an insulating component slides and abuts against a second inclined surface on a second insulating component. A second main board electrically connected to a first conductive plate is mounted on the second insulating component. The second main board is electrically connected to a charging interface corresponding to a through hole on the lamp body and a display screen corresponding to a display hole on the lamp body. A silicone waterproof cover is provided at the sealing cover of the through hole position. A light-transmitting shell is provided at the display hole position. A first waterproof gasket is provided between the light-transmitting shell and the lamp body, abutting against both. The rear cover is threadedly connected to the lamp body, and a third sealing ring is provided between the two. A second conductive plate is installed inside the rear cover, and a silicone switch cap is sealed and installed on the rear side. A tactile switch is electrically connected to the second conductive plate.

[0006] Using the above technical solution, the first motherboard is used to control the main LED and floodlight LEDs to turn on and off respectively, as well as to switch the main LED's lighting mode. When the main LED is lit, the light emitted by the main LED is reflected by the reflector and passes through the lens to achieve conventional lighting. When the floodlight LED is lit, the light emitted by the floodlight LED passes through the light-transmitting element and the lens to achieve floodlight lighting. This allows for multiple lighting modes. The charging interface and the second motherboard can charge the rechargeable battery that will be installed in the lamp body later. The second motherboard is connected to a display screen corresponding to the display hole on the lamp body, allowing users to check the remaining battery level for rechargeable batteries. The battery is charged promptly, thus effectively meeting user needs and enhancing the practicality of the firefighter lighting. Furthermore, by installing a first sealing ring between the lens and the lamp head housing, a second sealing ring between the lamp head housing and the lamp body, and a third sealing ring between the rear cover and the lamp body, along with a silicone waterproof cap at the through-hole, a first waterproof gasket between the light-transmitting shell and the lamp body, and a silicone switch cap sealed on the rear side of the rear cover, the firefighter lighting achieves comprehensive waterproofing.

Several floodlight lamp beads 152 corresponding to the light-transmitting element 13 are provided around the edge of the first main board 15. The right lamp housing 112 on the lamp head housing 11 is threadedly connected to the lamp body 2. A second sealing ring M2 is fitted into the annular groove provided at the left end of the lamp body 2. The right lamp housing 112 is threadedly connected to the lamp body 2 and is in sealing contact with the second sealing ring M2.

[0029] The inner wall of the lamp body 2 is provided with a circular limiting step surface 20. A first insulating component A1 and a second insulating component A2 are disposed inside the lamp body 2, positioned vertically opposite each other. Both are made of conventional insulating plastic materials such as PS, PP, ABS, PET, PC, etc. The first inclined surface at the bottom of the first insulating component A1 slides against the second inclined surface at the top of the second insulating component A2 to allow them to be installed inside the lamp body 2. Both the first and second inclined surfaces are designed with the left side lower than the right side. A second main board 4 is fixed to the second insulating component A2 by screws. The positive and negative conductive pins on the left side of the second main board 4 abut against the positive and negative conductive parts on the first conductive plate 17 to achieve electrical connection. One of the positive and negative conductive parts on the first conductive plate 17 is a circular metal ring, and the other is located on the circular... A circular metal sheet is located inside the annular metal ring. A display screen P1 is electrically connected to the top of the second main board 4. The display screen P1 corresponds to the display hole 21 on the lamp body 2 and the rectangular through hole A11 on the first insulating component A1. A light-transmitting shell 22 is provided at the position of the display hole 21. The light-transmitting shell 22 is made of light-transmitting hard plastic or light-transmitting silicone. A first waterproof pad F1 is provided between the light-transmitting shell 22 and the lamp body 2. The lower part of the first waterproof pad F1 is placed in the rectangular groove at the top of the light-transmitting shell 22. A charging interface 41 is electrically connected to the second main board 4. The charging interface 41 is installed in the mounting groove on the second insulating component A2. The charging interface 41 is at least one of a MicroUSB interface, a USB Type-C interface, and a Lightning interface. In this embodiment, the charging interface 41 is preferably a USB interface. The Type-C interface and charging interface 41 correspond to the through hole 23 on the lamp body 2. The through hole 23 is a through hole that connects the inside of the lamp body 2 with the outside. The through hole 23 is sealed with a silicone waterproof cover 5. In some embodiments, the silicone waterproof cover 5 is provided with a waterproof protrusion that is inserted into the through hole 23 and seals against the side wall of the through hole 23. The silicone waterproof cover 5 is connected to the rubber ring 51, which is fitted on the lamp body 2. The silicone waterproof cover 5 and the rubber ring 51 are integral structures. A second waterproof pad F2 is provided between the second insulating member A2 and the lamp body 2 to abut against both. The lower end of the charging interface 41 is inserted into the through hole on the second waterproof pad F2. Of course, the through hole on the second waterproof pad F2 corresponds to the through hole 23.

[0030] When the first insulating component A1 and the second insulating component A2 are installed inside the lamp body 2, their first inclined surfaces contact the second inclined surfaces and are offset to the left and right. That is, the left end of the first insulating component A1 is located to the left of the second insulating component A2 and is suspended. Then, the two are placed inside from the left end of the lamp body 2. After the second insulating component A2 contacts the limiting step surface 20 inside the lamp body 2, the first insulating component A1 is pushed to the right to contact the limiting step surface 20. The limiting step surface 20 limits the two. At the same time, the first insulating component A1 abuts against the light-transmitting shell 22, the light-transmitting shell 22 abuts against the first waterproof pad F1 and the inner wall of the lamp body 2, and the second insulating component A2 pushes the second waterproof pad F2 to abut against the inner wall of the lamp body 2, thus realizing the installation and waterproofing.

[0031] The rear cover 3 is screwed tightly to the lamp body 2. A third sealing ring M3 is fitted into the annular groove on the right end of the lamp body 2. The rear cover 3 and the lamp body 2 are screwed tightly together and make sealing contact with the third sealing ring M3. A second conductive plate 6 is installed inside the rear cover 3. A silicone switch cap 7 is sealed and installed on the rear side of the rear cover 3. A tactile switch 8 is electrically connected to the right side of the second conductive plate 6.

The positive and negative terminals on the left end of the rechargeable battery 24 are electrically connected to the positive and negative conductive pins on the right end of the second main board 4. The positive and negative terminals on the right end of the rechargeable battery 24 are electrically connected to the positive and negative conductive pins on the left end of the second conductive plate 6. The positive and negative terminals on the rechargeable battery 24 consist of a circular metal ring and a circular metal plate located within the circular metal ring. Both the first main board 15 and the second main board 4 are conventional circuit boards.

[0032] When the rechargeable battery 24 needs to be charged, one end of the charging cable plugs through the through hole 23 and is inserted into the charging interface 41, and the other end of the charging cable is inserted into the power socket. The charging cable is then connected to the rechargeable battery 24 via the charging control module on the second motherboard 4 and the positive and negative conductive pins on the right side, thus enabling the rechargeable battery 24 to be charged.

[0033] The first mainboard 15 controls the main LED 151 and floodlight 152 to turn on and off, and controls the lighting mode switching of the main LED 151. Furthermore, pressing the silicone switch cap 7 triggers the pressing of the tactile switch 8. The tactile switch 8 sends a signal back to the first mainboard 15, which then controls the main LED 151 and floodlight 152 to turn on and off, and controls the lighting mode switching of the main LED 151. Specifically, when the lights are off, pressing the tactile switch 8 once turns on the main LED 151 in focused high-intensity mode; pressing it again turns it off; pressing the tactile switch 8 again turns it on again in normal lighting mode (weaker than the focused high-intensity mode); pressing it again turns it off; and pressing the tactile switch 8 again turns it off. After pressing the touch switch 8, the main LED 151 lights up again in low light mode (the light is weaker than in normal light mode). Pressing it again turns the main LED 151 off. Pressing the touch switch 8 again turns the main LED 151 up in SOS mode. Pressing it again turns the main LED 151 off. Pressing the touch switch 8 again turns the main LED 151 up in strobe mode. Pressing it again turns the main LED 151 off. Pressing the touch switch 8 again turns the floodlight LED 152 up in floodlight mode. Pressing it again turns the floodlight LED 152 off. Pressing the touch switch 8 again turns the main LED 151 up, achieving focused high light mode. Follow the above steps to select the appropriate lighting mode. Of course, the order of the above lighting modes can be set as needed.

[0034] The display screen P1 is used to display one or more of the following: current lighting mode, percentage of remaining power, remaining discharge time, remaining power display square, brand logo, text, numbers, and serial number.
