Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, specifically to a multifunctional lighting device. Background Technology

[0002] Current desk lamps are generally only suitable for indoor use and cannot be adapted to outdoor lighting scenarios, mainly because:

[0003] 1. Traditional desk lamps have a fixed charging design, while outdoor desk lamps need to be directly exposed to sunlight for charging. Existing desk lamps cannot meet the charging needs of multiple scenarios.

[0004] 2. Traditional desk lamps are controlled by mechanical switches, which compromises the overall sealing.

[0005] Therefore, the market urgently needs a type of lighting fixture that can combine solar charging and conventional plug-in charging, making it suitable for both indoor and outdoor lighting. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a multifunctional lighting device that solves the problem that traditional technologies cannot simultaneously meet the needs of indoor and outdoor lighting and charging.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0031] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0032] Reference Figures 1 to 3 This application proposes a multifunctional lighting device, comprising:

[0033] The base 10 has a touch-sensing area 11 on its outer surface and a charging port 12 on its side wall. The charging port 12 is a Type-C charging port. The base 10 has a built-in rechargeable battery. The outer shell of the base 10 is integrally injection molded. The touch-sensing area 11 is isolated from the internal circuit by a 0.8mm thick acrylic plate. The charging port 12 has a side wall groove for embedding a silicone seal 13. After being filled, the silicone seal 13 is compressed and deformed to generate a radial sealing force.

[0034] The lampshade 20 is fixed to the top of the base 10. A solar panel 21 is provided on the top of the lampshade 20. A light-emitting circuit board 22 is integrated inside the lampshade 20. The light emitted by the light-emitting circuit board 22 facing downward will pass through at least a part of the curved shell 23 of the lampshade 20. The lampshade 20 is detachably connected to the base 10. The light-emitting circuit board 22 emits light downward, and the light path passes through at least a part of the curved shell 23 at the bottom of the lampshade 20. The light passing through the curved surface will generate a continuous light curtain on the curved surface. The total internal reflection light is continuously transmitted along the curved surface of the shell to form a uniform edge halo layer, which improves the visual effect.

[0035] The control circuit board integrates a dual-channel charging management circuit electrically connected to the solar panel 21 and the charging port 12, and a capacitance detection circuit coupled to the touch sensing area 11. The dual-channel charging management circuit includes a solar voltage regulator output circuit, a DC-DC step-down circuit, and a MOSFET switch group. When solar energy is input, the solar voltage regulator output circuit starts charging. When the charging port 12 is connected to a power source, the DC-DC step-down circuit activates power supply. The two power sources are selected by the MOSFET switch group and then charge the rechargeable battery, realizing seamless switching of energy supply modes.

[0036] It should be noted that since the solar power output circuit, DC-DC step-down circuit, and MOSFET switching group are all conventional circuit designs, they will not be described in detail here.

[0037] Combination Figure 2 In one embodiment, the base 10 includes a base 14 and a rod 15. A touch sensing area 11 is provided on the upper surface of the base 14, a charging port 12 is provided on the side wall of the base 14, and a rechargeable battery is built into the interior of the base 14.

[0038] The rod 15 is located at the center of the base 14 and extends upward. The rod 15 is tapered, wider at the bottom and narrower at the top, and is inserted into the bottom of the lampshade 20.

[0039] The pole 15 is designed as a tapered shape with a larger bottom and a smaller top, which helps to lower the center of gravity of the entire base 10, improve structural stability, and prevent easy tipping. The top of the pole 15 is equipped with a 2mm thick rubber sealing ring. When the lamp cover 20 is inserted, the rubber sealing ring is compressed to form a waterproof layer. The pole 15 has a pre-embedded wire channel to avoid damage to exposed cables.

[0040] Combination Figure 3 In one embodiment, the lampshade 20 includes an upper housing 24 and a lower housing 25. The solar panel 21 is fixed to the upper surface of the upper housing 24 and is used to directly face the sunlight for charging.

[0041] The light-emitting circuit board 22 includes a PCB board 16 and a number of LED beads 17. The PCB board 16 is fixed to the lower surface of the upper housing 24 and corresponds to the position of the solar panel 21. The number of LED beads 17 are fixed to the downward-facing surface of the PCB board 16.

[0042] The lower housing 25 has a card seat 18 at its center, which is used to dock with the top of the rod 15. The lower housing 25 is connected to the wall of the card seat 18 and the outer edge of the lower housing 25 through a light-transmitting curved housing 23.

[0043] To optimize light uniformity, the LED beads 17 are arranged in a ring array. Above the light-emitting circuit board 22 is the solar panel 21, and below it is the light-transmitting curved shell 23. Through the action of the light-transmitting curved shell 23, the light emitted by the LED beads 17 is diffused by total internal reflection, thereby achieving precise control of the ambient light field.

[0044] Preferably, the top of the card holder 18 is provided with three card holders 26, and the lower surface of the upper housing 24 is provided with three card posts 27. The connection between the upper housing 24 and the lower housing 25 is achieved by the card holders 26 and the card posts 27.

[0045] The three snap-fit ​​posts 27 form a circle, and the PCB board 16 has a hollow part in the middle. The PCB board 16 is snapped to the outer wall of the three snap-fit ​​posts 27 by the inner wall of the hollow part.

[0046] To overcome the risk of shell cracking caused by thermal deformation, three ABS snap-fit ​​posts 27 are distributed at 120°. Three positioning ribs are opened on the inner wall of the hollow part of the PCB board 16, which fit into the groove of the outer wall of the snap-fit ​​post 27 to achieve circumferential anti-rotation.

[0047] Optionally, the base 14 also has a built-in WIFI and Bluetooth connection module, which is electrically connected to the control circuit board. The WIFI and Bluetooth connection module is used to communicate with near-field devices to realize the switching and mode adjustment of the lighting device.

[0048] In summary, compared with the prior art, the above embodiments have at least the following technical advantages:

[0049] This application features both a solar panel 21 and a traditional charging port 12. The dual-path charging management circuit can switch between using the solar panel 21 or the charging port 12 to power the rechargeable battery, adapting to different charging scenarios indoors and outdoors. In addition, the traditional mechanical switch button has been eliminated and replaced with a touch-sensitive area 11 that uses a capacitance detection circuit to detect the touch, effectively improving the sealing of the lighting device.

[0050] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
