Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a lighting device. Background Technology

[0002] A flashlight is a common handheld electronic lighting tool. Most flat flashlights on the market have a push-button cover at the tail end of the flashlight shell, that is, the end facing away from the light body. This cover controls the flashlight's on / off state and allows switching between modes such as light intensity and wavelength, thereby controlling the final illumination effect.

[0003] In existing technology, some flashlights have a rotatable dial on the side of their casing. This dial allows for the selection of modes such as turning the light on / off, adjusting light intensity, and wavelength, enhancing the flashlight's practicality. However, due to the placement of the push-button cover and dial in existing flashlights, it is impossible to operate both with one hand simultaneously, which causes inconvenience and affects practicality.

[0041] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] This utility model provides a lighting device. (Refer to...) Figures 1 to 5As shown, the lighting device includes a cylindrical shell 1, a pressing cover 3, and a dial 4. The cylindrical shell 1 has a lighting element 2 at its first end and a first assembly groove 11 at its second end. A PCB board 12 electrically connected to the lighting element 2 is housed within the first assembly groove 11. The pressing cover 3 is movably positioned over the first assembly groove 11. The dial 4 is rotatably mounted on the side of the second end of the cylindrical shell 1. Pressing the pressing cover 3 causes a first control action on the PCB board 12, and rotating the dial 4 causes a second control action on the PCB board 12. One of the first and second control actions is to adjust the lighting mode of the lighting element 2 within its operating mode, while the other is to switch the operating mode of the lighting element 2.

[0043] In this embodiment, the first end of the cylindrical shell 1 has an illumination element 2, and the second end of the cylindrical shell 1 has a first assembly groove 11. A pressing cover 3 is movably mounted on the first assembly groove 11, and a PCB board 12 electrically connected to the illumination element 2 is disposed inside the first assembly groove 11. Meanwhile, a dial 4 is rotatably mounted on the side of the second end of the cylindrical shell 1. The pressing cover 3 and the dial 4 are both located at the second end of the cylindrical shell 1. Pressing the pressing cover 3 causes the PCB board 12 to perform a first control action, and rotating the dial 4 causes the PCB board 12 to perform a second control action. One of the first and second control actions is to control the illumination element 2 to adjust its lighting mode in the selected working mode, and the other is to control the illumination element 2 to switch its working mode. Since the pressing cover 3 and the dial 4 are both located at the same end of the cylindrical shell 1, the user can hold the cylindrical shell 1 with one hand, press the pressing cover 3 or rotate the dial 4 with their thumb, and hold the cylindrical shell 1 of the lighting device with the other four fingers, thus achieving one-handed operation of the pressing cover 3 and the dial 4. The structure is simple and the operation is convenient.

[0044] In this embodiment, a soft pressing pad 13 is provided between the pressing cover 3 and the PCB board 12, and a hard pressing head 31 is provided at the first end of the pressing cover 3. A pressure-sensitive element (not shown) is correspondingly provided on the PCB board 12. The pressure-sensitive element has a light pressure state and a heavy pressure state. When in the light pressure state, the soft pressing pad 13 presses the pressure-sensitive element; when in the heavy pressure state, the soft pressing pad 13 and the hard pressing head 31 jointly press the pressure-sensitive element. Specifically, when the pressing cover 3 is pressed, causing the pressing cover 3 to move but the hard pressing head 31 does not contact the soft pressing pad 13, the soft pressing pad 13 provides the pressing reaction force; when the hard pressing head 31 contacts the soft pressing pad 13, the hard pressing head 31 and the soft pressing pad 13 together provide the pressing reaction force, thereby realizing different tactile sensations of the two-stage switch. This arrangement can realize two-stage tactile pressing in the confined space of the lighting equipment. For example, a small two-stage succession switch with a first-stage travel of 0.4 mm and a second-stage travel of 0.2 mm is currently compatible.

[0045] Optionally, the lighting equipment can be selected in three operating modes: locked mode, duty mode, and tactical mode. Optionally, in this embodiment, the first control action controls the lighting component 2 to adjust the lighting mode in the selected operating mode by pressing the PCB board 12 with the pressing cover 3; the second control action controls the lighting component 2 to switch operating modes by rotating the dial 4.

[0046] Specifically, dial 4 switches to a different working mode every 90° rotation.

[0047] Specifically, when the lighting device is in locked mode, lightly or firmly press the cover 3 to illuminate the power indicator light.

[0048] Specifically, when the lighting equipment is in service mode, lightly press the cover 3 to preview the brightness mode, which is low, medium, and high brightness in sequence. Press the cover 3 firmly to lock the brightness. After locking, lightly press the cover 3 again to switch the brightness. Press it firmly again to turn off the lighting equipment.

[0049] Specifically, when the lighting equipment is in tactical mode, a light press of the cover 3 activates burst mode, while a harder press activates strobe mode. In a strong magnetic environment or when magnetic control fails, a light press of the cover 3 activates low brightness, while a harder press locks the low brightness mode. In the locked brightness mode, a hard press turns off the lighting equipment.

[0050] In some other alternative implementations, the first control action controls the lighting element 2 to switch operating modes by pressing the PCB board 12 with the press cover 3; in this embodiment, the second control action controls the lighting element 2 to adjust the lighting mode in the selected operating mode by rotating the dial 4. However, after the interchange, the press cover 3 only switches between two operating modes; for example, a light press of the press cover 3 activates the lock mode, and a hard press activates the duty mode.

[0051] Specifically, the second end of the press cover 3 is provided with a hinge shaft, and the press cover 3 is hinged to the first assembly groove 11 through the hinge shaft. The press cover 3 and the hinge shaft are hinged together, and the second end of the press cover 3 can swing relative to the first assembly groove 11, which is convenient for the user to press. In some other optional embodiments, the press cover 3 can also be set to a linear action, and the linear action direction can be the radial direction or the axial direction of the shell 1, which is not limited here.

[0052] In this embodiment, the PCB board 12 is provided with a USB port 121, and the press cover 3 is adapted to cover the USB port 121 when it is placed on the first assembly slot 11. Specifically, when the press cover 3 is open, the USB port 121 is open; when the press cover 3 is closed, the USB port 121 is closed. The press cover 3 enables the USB port 121 to be hidden. Specifically, the USB port 121 is provided for connecting an external power source to charge the lighting device.

[0053] In this embodiment, the PCB board 12 is provided with multiple magnetic sensitive elements (not shown), and the dial 4 is provided with a magnetic component. Rotation of the dial 4 causes the magnetic component to correspond to different magnetic sensitive elements, thereby enabling the PCB board 12 to generate a second control action. When the dial 4 is rotated, the magnetic component inside the dial 4 rotates accordingly. During the movement of the magnetic component, it can correspond to different magnetic sensitive elements, thus enabling the PCB board 12 to generate a second control action. Specifically, the magnetic sensitive element is set as a Hall effect magnetic switch.

[0054] Specifically, a groove 14 is provided on the second end side of the cylindrical shell 1, and the dial wheel 4 is rotatably disposed in the groove 14. Specifically, the groove 14 provides space for the dial wheel 4, avoids placing the dial wheel 4 outside the cylindrical shell 1, makes full use of the internal space of the cylindrical shell 1, and facilitates the reasonable arrangement of the dial wheel 4.

[0055] Specifically, a rotating shaft 141 is provided in the groove 14, and a dial 4 passes through the rotating shaft 141. The dial 4 is rotatably connected to the rotating shaft 141. Specifically, the two opposite ends of the rotating shaft 141 are respectively connected to the inner wall of the groove 14 at the corresponding ends.

[0056] Optionally, the impeller has a second assembly slot (not shown), and the magnetic component is fixedly disposed in the second assembly slot.

[0057] In this embodiment, the lighting device also includes a ring 5, which is disposed on the side of the second end of the housing 1 and opposite to the dial 4. The ring 5 is designed to allow the user's fingers to pass through, making it easy to carry. Specifically, the ring 5 is located on the side of the press cover 3 away from its hinge end. With this configuration, when the user holds the lighting device, the thumb presses the top of the press cover 3, the other four fingers grip the housing 1 of the lighting device, and the index finger passes through the ring 5, thereby enabling one-handed holding and operation of the lighting device.

[0058] Specifically, the ring 5 is detachably mounted on the housing 1. This design allows the ring 5 to be removed in situations where it is not necessary to carry it, and also facilitates the replacement of the ring 5.

[0059] Specifically, the cylindrical shell 1 has a positioning groove 151, and the ring 5 has a corresponding positioning head 51 that is inserted into the positioning groove 151. The cooperation between the positioning groove 151 and the positioning head 51 enables the ring 5 to be quickly positioned during assembly, thereby improving the assembly efficiency of the ring 5.

[0060] Specifically, the ring 5 and the shell 1 are fixedly connected by a fastening screw 52. The ring 5 has a first hole 53, and the shell 1 has a corresponding second hole 152. The fastening screw 52 passes through the first hole 53 and is threaded into the second hole 152. Specifically, when the positioning head 51 is inserted into the positioning groove 151, the ring 5 is assembled in place, at which point the first hole 53 and the second hole 152 are in a coaxial communication position. Then, the fastening screw 52 is installed, passing through the first hole 53 and threaded into the second hole 152, thereby reliably fixing the ring 5 to the shell 1.

[0061] In this embodiment, a lamp groove 16 is provided at the first end of the cylindrical shell 1, and the lighting element 2 is disposed in the lamp groove 16. The cylindrical shell 1 has a heat absorption cavity 101 inside, and a heat absorber is placed inside the heat absorption cavity 101. The lighting element 2 includes a substrate 21 and a lamp body 22 disposed on the substrate 21, and the substrate 21 is fixedly connected to the lamp groove 16. The heat absorber is used to absorb the heat generated by the lamp body 22 and transferred to the substrate 21. Specifically, when the lighting device is working, the lamp body 22 emits light and generates heat and transfers the heat to the substrate 21, and then the substrate 21 transfers the heat to the heat absorber in the heat absorption cavity 101 through the inner wall between the lamp groove 16 and the heat absorption cavity 101. During the heat absorption process, the temperature of the heat absorber rises, effectively absorbing the heat generated by the lamp body 22 and transferred to the substrate 21, alleviating the rapid temperature rise of the lamp body 22 when emitting light, and ensuring the reliable operation of the lighting device for a long time.

[0062] For example, the lamp body 22 is configured as an LED lamp. The heat absorber effectively absorbs the heat generated by the lamp body 22, reducing the degree of brightness decay of the LED, etc., thereby maintaining the LED lamp at high brightness for a long time.

[0063] For example, the substrate 21 is made of copper to further facilitate heat transfer.

[0064] For example, the heat absorber is configured as phase changer 17, and the specific heat capacity of the heat absorber is greater than that of the shell 1. Optionally, the heat absorber can be a liquid substance, such as water, in its initial state. Both the shell 1 and the substrate 21 are made of metal, such as copper. The heat emitted by the LED lamp is transferred to the shell 1 through the substrate 21. Because the shell 1 has a high thermal conductivity, it can effectively transfer the heat it carries to the air through natural convection. The heat absorber in the heat absorption cavity 101 is in contact with the shell 1, and the heat of the shell 1 is transferred to the heat absorber at the same time. At the same time, the heat absorber interacts with the shell 1 and transfers heat to each other. However, because the specific heat capacity of the heat absorber is much greater than that of the shell 1, the heat absorber also stores some heat when interacting with the shell 1, which improves the heat handling capacity of the entire system in a short time, reduces the overall temperature of the shell 1, and realizes the function of high power output of the product in a short time.

[0065] In some other alternative implementations, the heat absorber is initially solid and can change from solid to liquid during the heat absorption process.

[0066] In some alternative implementations, refer to Figure 4 As shown, a first receiving groove 171 is formed on the outer wall of the cylindrical shell 1. The base plate 21 is fixedly disposed on the groove wall of the lamp slot 16 facing the first receiving groove 171. A first cover plate 172 is provided on the outer cover of the first receiving groove 171. The first cover plate 172 and the first receiving groove 171 together form a heat absorption cavity 101. Specifically, the first receiving groove 171 is formed on the side of the cylindrical shell 1 biased towards the first end, and the first receiving groove 171 is spaced apart from the lamp slot 16. The heat generated by the lamp body 22 in the lamp slot 16 is transferred through the base plate 21 and the inner wall of the cylindrical shell 1 between the first receiving groove 171 and the lamp slot 16.

[0067] Specifically, the first cover plate 172 and the first receiving groove 171 can be fixedly connected by external connectors such as screws.

[0068] Furthermore, a first mounting groove 173 is formed on the outer wall of the shell 1, a first receiving groove 171 is formed at the bottom of the first mounting groove 173, and a first cover plate 172 is fixedly embedded in the first mounting groove 173. Specifically, the first mounting groove 173 provides a reliable mounting space for the first cover plate 172. The depth of the first mounting groove 173 is greater than or equal to the thickness of the first cover plate 172. When the first cover plate 172 is placed in the first mounting groove 173, the first cover plate 172 is completely located within the first mounting groove 173, preventing the first cover plate 172 from protruding outward and ensuring aesthetics. Specifically, the first mounting groove 173 and the first cover plate 172 are in a clearance fit. With this design, when disassembling the first cover plate 172, after loosening and removing the screws, the first mounting groove 173 can be inverted to allow the first cover plate 172 to fall out of the first mounting groove 173, facilitating disassembly.

[0069] Furthermore, a first sealing ring 181 is provided between the first mounting groove 173 and the first cover plate 172. The first sealing ring 181 is used to seal the gap between the first mounting groove 173 and the first cover plate 172, ensuring the airtightness of heat absorption. Specifically, an annular first fixing groove 182 is provided at the bottom of the first mounting groove 173, and the first sealing ring 181 is installed in the first fixing groove 182. The first fixing groove 182 provides installation space for the first sealing ring 181, ensuring reliable and stable installation of the first sealing ring 181, and also ensuring the effective positioning of the first sealing ring 181.

[0070] Optionally, the first sealing ring 181 may be made of rubber.

[0071] In some alternative implementations, refer to Figure 5As shown, a mounting block 6 is fixedly disposed within the lamp slot 16, and a base plate 21 is fixedly disposed on the mounting block 6. The mounting block 6 has a second receiving groove 61, and a second cover plate 63 is provided over the second receiving groove 61. The second cover plate 63 and the second receiving groove 61 together form a heat absorption cavity 101. Specifically, this embodiment differs from the above embodiment in that the heat absorption cavity 101 is opened within the mounting block 6, and the mounting block 6 is disposed within the lamp slot 16. Therefore, it is not necessary to specially create a groove structure on the cylindrical shell 1, which simplifies the structure of the cylindrical shell 1 to a certain extent. The heat generated by the lamp body 22 within the lamp slot 16 is transferred through the base plate 21 and the inner wall of the cylindrical shell 1 between the second receiving groove 61 and the lamp slot 16.

[0072] Specifically, the second cover plate 63 and the second receiving groove 61 can be fixedly connected by external connectors such as screws.

[0073] Furthermore, a second mounting groove 62 is formed on the outer wall of the mounting block 6, and a second receiving groove 61 is formed at the bottom of the second mounting groove 62. The second cover plate 63 is fixedly embedded in the second mounting groove 62. Specifically, the second mounting groove 62 provides reliable mounting space for the second cover plate 63. The depth of the second mounting groove 62 is greater than or equal to the thickness of the second cover plate 63. When the second cover plate 63 is placed in the second mounting groove 62, the second cover plate 63 is completely located within the second mounting groove 62, preventing the second cover plate 63 from protruding outward and saving space. Specifically, the second mounting groove 62 and the second cover plate 63 are clearance-fitted. With this design, when removing the second cover plate 63, the screws can be loosened and removed, and the second mounting groove 62 can be inverted to allow the second cover plate 63 to fall out of the second mounting groove 62, facilitating disassembly.

[0074] Furthermore, a second sealing ring 64 is provided between the second mounting groove 62 and the second cover plate 63. The second sealing ring 64 is used to seal the gap between the second mounting groove 62 and the second cover plate 63, ensuring the airtightness of the heat absorption chamber 101. Specifically, an annular second fixing groove 621 is provided at the bottom of the second mounting groove 62, and the second sealing ring 64 is installed in the second fixing groove 621. The second fixing groove 621 provides installation space for the second sealing ring 64, ensuring reliable and stable installation of the second sealing ring 64, and also ensuring the effective positioning of the second sealing ring 64.

[0075] Optionally, the second sealing ring 64 may be made of rubber.

[0076] The lighting device provided in this embodiment can be a flashlight or other devices with the same lighting function, and no further limitations are imposed here.

[0077] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
