Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and more specifically, to a lighting device that is easy to adjust. Background Technology

[0002] In the field of lighting technology, LED lighting devices have been widely used in various scenarios due to their advantages such as energy saving and environmental protection. However, existing products still have many shortcomings in terms of structural design and user experience.

[0003] In terms of circuit layout, traditional lighting devices often have separate light source boards and circuit adjustment modules. The circuit board needs to occupy separate internal space in the lamp body, which prevents the light source board from sinking down close enough to the light emitter. The spacing between the lamp beads and the light emitter is also unreasonable, easily resulting in a light spot phenomenon where the center is too bright and the edges are dark, affecting the uniformity of lighting. Some products adopt a compact layout to save space, which may also lead to poor heat dissipation of circuit components, accelerate light decay, and shorten the life of the lamp.

[0004] The adjustment mechanism design has significant flaws. Most adjustment switches are directly exposed on the outer casing, which not only detracts from the overall aesthetics of the lamp but also makes them susceptible to accidental activation by external forces, leading to malfunctions. Some switches are located close to the lamp holder, posing a safety hazard of accidental electric shock to users. Furthermore, the linkage between the switches and the internal DIP switch components is not stable enough, frequently resulting in tripping and jamming during adjustment, affecting the reliability of the adjustment.

[0005] Furthermore, some lighting fixtures suffer from unreasonable assembly structure designs, complex connection methods between the light emitter and the housing, inconvenient disassembly and maintenance, and limited lamp holder compatibility, making it difficult to meet the usage needs of different installation scenarios and restricting the product's applicability. These issues collectively necessitate improvements to the practicality, safety, and user experience of existing lighting devices. Summary of the Invention

[0006] This utility model provides an easily adjustable lighting device to solve the technical problems in the prior art where the lighting device has separate light source board and circuit module, which occupy internal space, resulting in uneven light output due to unreasonable spacing between lamp beads and light emitter cover; the adjustment switch protrudes outward, affecting aesthetics and posing a risk of electric shock due to its proximity to the lamp head; and the switch has poor linkage stability with internal components, making it difficult to balance light output effect, aesthetics, safety and adjustment reliability.

[0007] This utility model provides an easily adjustable lighting device, including a light-emitting cover for light transmission, a housing for supporting components, a lamp holder for power supply connection, and a light source board integrating an LED light source. The light source board integrates a circuit module for circuit adjustment and a DIP switch for switching circuit states. The DIP switch is arranged laterally on the side of the light source board near the housing, with its knob extending parallel to the axial direction of the lighting device. The upper region of the housing has an inwardly recessed receiving compartment for concealing the switch. An adjustment switch that can drive the DIP switch is installed within the receiving compartment. The adjustment switch includes a sliding part for hand operation and a locking part linked to the DIP switch. The locking part extends perpendicular to the axial direction of the lighting device and is detachably locked to the knob of the DIP switch. Under external force, the sliding part moves the locking part in a direction perpendicular to the axial direction, thereby driving the knob to move and switch positions to achieve circuit adjustment.

[0008] Furthermore, the receiving compartment is configured as an annular recessed structure extending along the circumference of the outer shell, and the sliding part of the adjusting switch is correspondingly configured as an annular structure adapted to the receiving compartment, with the annular sliding part distributed around the circumference of the outer shell.

[0009] Furthermore, the outer surface of the annular sliding part is integrally formed with multiple anti-slip protrusions for increasing friction, and the anti-slip protrusions are evenly distributed along the circumference of the annular sliding part.

[0010] Furthermore, the housing has an axially extending mounting post inside, and the light source plate has a clearance hole at the position corresponding to the mounting post. A bolt passes through the clearance hole and is threaded to the mounting post to fix the light source plate inside the housing.

[0011] Furthermore, the edge of the light-emitting cover is provided with a buckle, and the outer shell is provided with a slot corresponding to the buckle position. The light-emitting cover can be detachably connected to the outer shell through the cooperation of the buckle and the slot.

[0012] Furthermore, the circuit module includes a drive circuit unit for stable power supply. The positive input terminal of the drive circuit unit is electrically connected to the positive contact of the lamp holder via a wire, and the negative input terminal is electrically connected to the negative contact of the lamp holder via a wire.

[0013] Furthermore, the LED beads on the light source board are evenly arranged along the circumference to form a ring-shaped light source area, and the DIP switch is located on the periphery of the light source board near the outer casing.

[0014] Furthermore, the recessed depth of the receiving compartment is not less than the overall thickness of the regulating switch, and after assembly, the outer surface of the regulating switch is flush with the outer shell surface or recessed inward.

[0015] Furthermore, the locking part of the adjustment switch is designed as a U-shaped structure. The opening direction of the U-shaped structure is perpendicular to the axis of the lighting device, and the width of the opening is adapted to the width of the DIP switch knob. After the knob is locked into the U-shaped structure, the locking part can drive the knob to move stably, avoiding the phenomenon of disengagement during the adjustment process.

[0016] Furthermore, the lamp holder is a screw-type lamp holder or a plug-in lamp holder.

[0017] The beneficial effects of this utility model are:

[0018] This utility model provides an easily adjustable lighting device. Through the coordinated structural design of the light source board, adjustment switch, and housing, it achieves comprehensive optimization of uniform light output, convenient adjustment, beautiful appearance, and safe use, effectively solving the pain points of existing technologies.

[0019] The integrated circuit module and DIP switch on the light source board eliminate the independent space occupied by traditional separate circuit boards, allowing the light source board to be fully recessed to ensure a reasonable spacing between the LEDs and the light emitter cover, and that the light can fully cross and cover the light, completely solving the problem of uneven light output caused by improper spacing in traditional devices. At the same time, circuit integration reduces the number of components, simplifies the internal layout, reduces the heat dissipation burden of the circuit, slows down the light decay rate, and extends the overall lifespan of the lamp, overcoming the defects of poor heat dissipation and rapid light decay of traditional separate layouts.

[0020] The adjustment switch is fitted into the recessed housing of the outer casing, with the switch completely hidden within the housing and not protruding from the surface of the casing, avoiding the problem of traditional exposed switches damaging the appearance of the lamp. Furthermore, the adjustment switch is located on the upper part of the casing, away from the lamp head area, so users do not need to approach the powered lamp head when operating it, greatly reducing the risk of accidental electric shock and solving the safety hazards of traditional switches being close to the lamp head. At the same time, the adjustment switch is stably engaged with the DIP switch knob through the snap-fit ​​part, and the sliding part is not prone to disengagement or jamming when moving the snap-fit ​​part, significantly improving the reliability of adjustment and overcoming the instability problem of traditional linkage structures.

[0021] The upper housing can also be designed as a ring structure, with the adjustment switch corresponding to the ring-shaped sliding part. Users can touch and operate it in any direction along the circumference of the housing without having to deliberately search for the switch position, further improving the ease of operation. The anti-slip protrusions added to the ring-shaped sliding part can increase the friction of the hand and prevent slippage during adjustment, optimizing the user experience. In addition, the lamp holder is compatible with both screw-in and plug-in types, which can meet the installation scenarios of E26 / E27 / E14 screw-in and G9 plug-in installation scenarios, solving the limitation of the single compatibility of traditional lamp holders and broadening the application range of the product.

[0022] The overall device has a simple structure and is easy to assemble. It comprehensively solves the problems of uneven light output, poor aesthetics, high safety risks, and narrow adaptability in existing technologies, meets the lighting needs of multiple scenarios such as home and office, and greatly improves the user experience and product practicality.

[0044] The easily adjustable lighting device according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0045] This utility model provides an easily adjustable lighting device, aiming to solve the technical problems in the prior art where the lighting device has separate light source board and circuit module, which occupy internal space, resulting in unreasonable spacing between lamp beads and light emitter cover, causing uneven light output; the adjustment switch protrudes outward, affecting aesthetics and posing a risk of electric shock due to its proximity to the lamp head; at the same time, the switch has poor linkage stability with internal components, making it difficult to balance light output effect, aesthetics, safety and adjustment reliability.

[0046] like Figures 1 to 9 As shown, the easily adjustable lighting device of this utility model includes a light-emitting cover 1 for light transmission, a housing 2 for supporting components, a lamp holder 3 for power supply connection, and a light source board 4 integrating an LED light source. The light source board 4 integrates a circuit module for realizing circuit adjustment function and a DIP switch 41 for switching circuit states. The DIP switch 41 is arranged laterally on the side of the light source board 4 near the housing 2, and its knob 411 extends parallel to the axial direction of the lighting device. The upper part of the housing 2 is provided with an inwardly recessed receiving compartment 21 for hiding the switch. The receiving compartment 21 is equipped with an adjustment switch 5 that can drive the DIP switch 41 to operate. The adjustment switch 5 includes a sliding part 51 for hand operation and a locking part 52 that is linked with the DIP switch 41. The extension direction of the locking part 52 is perpendicular to the axial direction of the lighting device and is detachably locked to the knob 411 of the DIP switch 41. Under the action of external force, the sliding part 51 drives the locking part 52 to translate in a direction perpendicular to the axial direction, thereby driving the knob 411 to move and switch positions to realize circuit adjustment.

[0047] like Figure 7 , Figure 8As shown, the DIP switch 41 is arranged horizontally on the side of the light source board 4 near the housing 2. Traditional lighting devices often use a separate circuit board between the light source board and the screw base to achieve color temperature or power adjustment. This results in the light source board not being able to fully sink, and the LEDs being too close to the light emitter cover, affecting the light output. However, this invention integrates the DIP switch 41 and the circuit module onto the light source board 4, eliminating the space occupied by a separate circuit board. This allows the light source board 4 to sink fully towards the light emitter cover 1, ensuring the distance between the LEDs and the light emitter cover 1 is within a reasonable range. The light can achieve sufficient cross-coverage before reaching the light emitter cover 1, completely solving the problem of uneven light output in traditional devices and avoiding the visible arrangement of LEDs. Meanwhile, the DIP switch 41 is positioned close to the housing 2, allowing the adjustment switch 5 to be correspondingly arranged in the upper area of ​​the housing 2. This keeps the adjustment switch away from the lamp holder, and the horizontal arrangement eliminates the need for the user to move their hand towards the lamp holder 3 during operation. This avoids operational limitations in confined spaces and keeps the user away from the powered lamp holder 3, structurally eliminating the risk of accidental electric shock and balancing ease of operation with safety. Furthermore, the integrated design of the DIP switch 41 and the light source board 4 reduces the number of wire connections or soldering steps in traditional separate structures, simplifying the assembly process and reducing the risk of circuit failures caused by loose connections. The light source board 4 is secured to the mounting posts 22 inside the housing 2 with bolts. Figure 5 As shown, the bolt passes through the clearance hole 42 of the light source plate 4 and is threadedly connected to the mounting post 22. The DIP switch 41 is stably fixed with the light source plate 4, ensuring that the locking part 52 of the adjustment switch 5 and the dial 411 of the DIP switch 41 are always stably linked, reducing the occurrence of tripping or jamming during adjustment. In addition, as Figure 7 As shown, the LED beads on the light source board 4 are evenly arranged in the circumferential direction to form a ring light source area. The DIP switch 41 is located on the periphery of the light source board 4 near the outer shell 2. This layout not only avoids the DIP switch 41 from blocking the light of the LED beads, but also makes full use of the idle space on the periphery of the light source board 4, maximizes the space utilization, ensures the integrity of the ring light source, and further enhances the uniformity of light output.

[0048] like Figure 4 , Figure 9As shown, the receiving chamber 21 is a ring-shaped recessed structure extending along the circumference of the outer shell 2. The sliding part 51 of the adjustment switch 5 is correspondingly designed as a ring-shaped structure adapted to the receiving chamber 21, with the ring-shaped sliding part 51 distributed around the circumference of the outer shell 2. The ring-shaped adjustment switch makes it easier for users to find the switch position. The ring-shaped sliding part 51 is distributed along the circumference of the outer shell 2, allowing users to touch and operate it from any angle, eliminating the need to deliberately search for a single sliding direction or operating point like with traditional linear switches. This is especially suitable for scenarios where lighting fixtures have various installation angles, as the hand can naturally conform to the circumference of the outer shell 2 to complete the adjustment, significantly reducing the difficulty of operation. At the same time, the outer surface of the ring-shaped sliding part 51 is integrally formed with multiple anti-slip protrusions evenly distributed along the circumference, which can effectively increase the friction between the hand and the sliding part 51. Even if the hand is wet or slightly oily, it can prevent slippage during adjustment, ensuring precise adjustment. From an aesthetic and protective perspective, the recessed depth of the annular receiving chamber 21 is not less than the overall thickness of the regulating switch 5. After assembly, the outer surface of the annular sliding part 51 is flush with the surface of the outer shell 2 or recessed inward, completely hidden inside the receiving chamber 21. This avoids the problem of the outer surface of the traditional linear switch breaking through and damaging the flat appearance of the outer shell 2, and improves the visual quality of the lamp. The recessed receiving chamber 21 can also protect the annular sliding part 51, reduce external impact or dust and moisture erosion, extend the service life of the regulating switch 5, and is suitable for humid and dusty environments. Regarding linkage stability, the annular sliding part 51 and the locking part 52 are integrated structures. The locking part 52 is designed as a U-shaped structure, with the opening direction of the U-shaped structure perpendicular to the axial direction of the lighting device. The opening width is adapted to the width of the dial switch 411. When the annular sliding part 51 slides along the circumference, the U-shaped locking part 52 can stably drive the dial switch 411 to translate in a direction perpendicular to the axial direction. The annular sliding path makes the locking part 52 more evenly stressed, avoiding the stress concentration problem caused by the single-direction sliding of the traditional linear switch, reducing the wear of the locking part 52 and the dial switch 411, ensuring the long-term stability of the linkage structure, and reducing the probability of adjustment failure.

[0049] The edge of the light emitter 1 is provided with a buckle 11, and the outer shell 2 has a corresponding slot 23. The light emitter 1 is detachably connected to the outer shell 2 through the cooperation of the buckle 11 and the slot 23. This connection method facilitates the disassembly and maintenance of the light source board 4 or the cleaning of the light emitter 1. The circuit module includes a drive circuit unit for stable power supply. The positive input terminal of the drive circuit unit is electrically connected to the positive contact of the lamp holder 3 through a wire, and the negative input terminal is electrically connected to the negative contact of the lamp holder 3 through a wire, ensuring stable power transmission from the lamp holder 3 to the circuit module, avoiding lighting flicker, and ensuring the stability of the lamp. The lamp holder 3 is a screw-type lamp holder or a plug-in type lamp holder, which can be adapted to E26 / E27 / E14 screw-type installation and G9 plug-in installation, broadening the product's applicability and meeting the needs of different installation scenarios.

[0050] In summary, this utility model, through its core design of "DIP switch 41 integrated into light source board 4" and "ring-shaped adjustment switch 5," combined with other cooperating structures, comprehensively solves the problems of uneven light output, inconvenient operation, high safety risks, and poor aesthetics in existing lighting devices. It features a simple structure, convenient assembly, and can meet the lighting needs of various scenarios such as homes and offices, significantly improving the product's practicality and market competitiveness.

[0051] Of course, other structures and working principles of the easily adjustable lighting device are understandable and achievable by those skilled in the art, and will not be described in detail in this utility model.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
