Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to an energy-saving lamp. Background Technology

[0002] With increasing societal demands for energy efficiency and lighting quality, new energy-saving lighting fixtures, represented by LEDs, have been widely applied in commercial and residential environments. However, different installation locations (such as high-ceilinged halls, conference rooms, and ordinary ceilings) have significantly different lighting requirements. For example, some areas require focused lighting to highlight specific areas, while other areas require floodlighting to provide soft, uniform, and large-area illumination.

[0003] Existing recessed energy-saving luminaires typically use a fixed spatial design for their internal optical components (such as lenses and reflectors). This means that once the luminaire is installed, its beam angle and illumination range are locked, making it impossible to flexibly change them according to the actual decoration style, lighting needs, or subsequent functional adjustments. When the installation environment or lighting task changes, users often need to replace the entire luminaire to achieve the new lighting effect, which not only leads to high maintenance costs but also wastes resources.

[0004] Especially for luminaires requiring adjustable beam height, some designs employ adding replaceable optical components externally. While this achieves the functionality, the process is cumbersome and prone to introducing dust or causing secondary contamination of the optical components during adjustment, making it difficult to achieve convenient fine-tuning and stable control after installation. Therefore, designing a compact, easy-to-operate, and energy-efficient luminaire capable of stable stepless adjustment of the optical lens height within the luminaire itself is a critical issue that urgently needs to be addressed in the current lighting technology field.

[0005] Therefore, this utility model proposes an energy-saving lamp to address the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an energy-saving lamp, which aims to improve the structural problems of existing lamps that cannot flexibly adjust the beam angle according to the installation environment and have low heat dissipation efficiency under high-power lighting, resulting in shortened component life.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving lamp, comprising: a mounting shell, a housing disposed inside the mounting shell, and a high-transparency glass that seals the bottom opening of the mounting shell; the outer wall of the housing is integrally provided with multiple heat sinks; the top wall of the inner cavity of the housing is fixed with a circuit board for driving the light source, and the lower surface of the circuit board is fixedly connected with lamp beads.

[0008] The energy-saving lamp is equipped with a lighting adjustment mechanism, which is located inside the housing and includes a transparent cover, an optical lens, a limiting post, and an adjustment screw.

[0009] The optical lens is fixedly installed inside the transparent cover, which slides against the inner wall of the housing via its outer wall to allow for vertical movement along the axis of the housing's inner cavity. One end of the limiting post is fixedly connected to the top wall of the housing's inner cavity, and the transparent cover is slidably fitted onto the outer wall of the limiting post, which provides precise positioning and guidance for the transparent cover.

[0010] Furthermore, the adjusting screw rotates through the mounting shell and is rotatably disposed inside the shell. The threaded section of the adjusting screw is threaded onto the transparent cover. The rotational motion of the adjusting screw is converted into the linear motion of the transparent cover. The rotation of the adjusting screw drives the transparent cover to adjust the height of the optical lens relative to the lamp beads. Through this height change, stepless adjustment from focused light to floodlight can be achieved before or after the lamp is installed.

[0011] Preferably, the energy-saving lamp further includes a heat dissipation mechanism, which includes a small fan. The small fan is fixedly connected to the outer wall of the mounting shell by mounting bolts and is used to blow external cold air towards the heat dissipation fins on the outside of the shell. The upper side of the mounting shell is provided with heat dissipation holes for discharging hot air through the heat dissipation holes, thereby achieving active and efficient forced convection heat dissipation.

[0012] Preferably, the outer cover of the lamp bead is provided with a reflector, which is fixedly connected to the inner cavity of the housing. The reflector is used to collect the light emitted by the lamp bead and guide it to the optical lens to improve the light energy utilization efficiency.

[0013] Preferably, a torsion spring is installed on the side wall of the mounting housing in a lever-type manner. The torsion spring is used to install and fix the lamp in the ceiling using elastic force, so as to achieve quick and convenient embedded installation.

[0014] Preferably, a terminal block is fixedly connected to the upper surface of the housing, and a terminal block is provided at the top of the housing. The terminal block is rotated and engaged inside the terminal block to achieve electrical connection. This structure facilitates quick power-on and maintenance of the lamp.

[0015] Preferably, the air inlet side of the small fan is provided with a dust cover, which is used to filter the external cold airflow entering the lamp. The mounting bolts pass through the inside of the dust cover and fix the dust cover to the air inlet side of the small fan, ensuring the cleanliness of the heat dissipation airflow and preventing dust from adhering and affecting heat dissipation.

[0016] Preferably, the upper end of the limiting post is fixedly connected to the top wall of the inner cavity of the housing, and the limiting post is located on the side opposite to the adjusting screw. The limiting post and the adjusting screw together provide dual guidance and limiting for the transparent cover, ensuring the smoothness of the lifting and lowering of the optical lens.

[0017] Preferably, the terminal receives external power and then outputs it to the circuit board, which is used to control the stable light emission of the LED beads.

[0018] This utility model has the following beneficial effects: 1. In this utility model, by setting the lighting adjustment mechanism inside the housing, the optical lens is driven to adjust its height by rotating the adjusting screw under the guidance of the limiting post. This solves the problem of fixed beam angle or complex adjustment structure in the prior art, and achieves the technical effect of stepless adjustment from focused light to floodlight according to different installation environments and lighting needs.

[0019] 2. In this utility model, by setting an active heat dissipation mechanism inside the lamp, a small fan is used to blow the external cold air filtered by the dust cover to the heat sink integrated on the outside of the housing. This solves the problems of low passive heat dissipation efficiency and easy heat accumulation in internal components of high-power lighting lamps, which leads to light decay and shortened lifespan. It achieves the technical effect of significantly improving heat dissipation efficiency, extending the lifespan of the lamp, and maintaining stable light efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1 to 4 This utility model provides an energy-saving lamp, which aims to solve the structural problems in the prior art where lamps cannot flexibly adjust the beam angle according to the installation environment and where low heat dissipation efficiency under high-power lighting leads to a shortened component life.

[0024] The main structure of the energy-saving lamp includes a mounting shell 6 as an external support base, and a housing 1 set inside the mounting shell 6 to support the lighting components. Multiple heat sinks 2 are integrally provided on the outer wall of the housing 1. The heat sinks 2 are evenly distributed around the circumference of the housing 1 to increase the contact area between the housing 1 and the air to improve the heat exchange efficiency, thereby assisting the internal components of the housing 1 to cool down quickly.

[0025] A high-transparency glass 7 is provided at the bottom opening of the mounting housing 6. The high-transparency glass 7 seals the bottom opening of the mounting housing 6 and is fixedly connected to the bottom edge of the mounting housing 6. It is used to protect the precision components inside the mounting housing 6 from external physical damage while ensuring high light transmittance. A circuit board 501 is fixed to the top wall of the inner cavity of the housing 1. An LED bead 502 is fixedly connected to the lower surface of the circuit board 501. The LED bead 502 is a light source component and is driven and controlled by the circuit board 501. The circuit board 501 is set close to the top wall of the inner cavity of the housing 1, which is conducive to the direct conduction of the heat generated by the LED bead 502 to the housing 1 and the external heat sink 2.

[0026] In order to achieve a stable connection between the lamp and the external power supply, a terminal block 3 is fixedly connected to the upper surface of the housing 1, and a terminal block 4 is provided at the corresponding position on the top of the housing 1. The terminal block 3 rotates and engages inside the terminal block 4 to achieve electrical connection. After receiving the external power input, the terminal block 3 outputs the current to the circuit board 501, thereby controlling the lamp bead 502 to emit light. This rotating engagement structure facilitates the quick disassembly and maintenance of the internal components of the lamp.

[0027] To address the issue of insufficient efficiency in passive heat dissipation alone, the lamp integrates a heat dissipation mechanism 9 on the mounting housing 6. The heat dissipation mechanism 9 includes a small fan 902, which is fixedly connected to the outer wall of the mounting housing 6 by mounting bolts 904. The air outlet direction of the small fan 902 is aligned with the heat sink 2 on the outer side of the housing 1 to provide forced convection active air cooling. A heat dissipation hole 901 is provided at a corresponding position on the upper side of the mounting housing 6. The heat dissipation hole 901 is used to blow hot air in by the small fan 902 and discharge the hot air carrying heat to the outside of the mounting housing 6, thereby forming a complete air circulation heat dissipation cycle.

[0028] Meanwhile, in order to meet the lighting needs of different scenarios, the housing 1 also integrates a lighting adjustment mechanism 5. The lighting adjustment mechanism 5 changes the position of the internal optical components through mechanical transmission, thereby cooperating with the lamp bead 502 to switch between focused and floodlight modes.

[0029] To solve the above-mentioned technical problems, the energy-saving lamp also includes a lighting adjustment mechanism 5. Furthermore, the lighting adjustment mechanism 5 forms a specific structural fit and connection relationship with the housing 1 and the lamp bead 502 to achieve precise preset adjustment of the beam angle.

[0030] The lighting adjustment mechanism 5 is located inside the housing 1 and mainly consists of a transparent cover 504, an optical lens 505, a limiting post 506, and an adjusting screw 507. The transparent cover 504 serves as the carrier of the lighting adjustment mechanism 5, and the optical lens 505 is fixedly installed inside it. The optical lens 505 is used to refract the light beam emitted by the lamp bead 502.

[0031] The transparent cover 504 slides with the inner wall of the housing 1 through its outer wall. The sliding of the transparent cover 504 can drive the optical lens 505 to move along the inner cavity axis of the housing 1, thereby changing the relative distance between the optical lens 505 and the light source lamp bead 502.

[0032] To ensure the stability of the transparent cover 504 during sliding and to prevent its rotation, a limiting post 506 is fixedly connected to the top wall of the inner cavity of the housing 1. One end of the limiting post 506 is fixedly connected to the top wall of the inner cavity of the housing 1. The transparent cover 504 is slidably sleeved on the outer wall of the limiting post 506. The upper end of the limiting post 506 is fixedly connected to the side of the top wall of the inner cavity of the housing 1 opposite to the adjusting screw 507. This sleeved and limiting structure ensures that the transparent cover 504 can only slide up and down along the axial direction of the limiting post 506, effectively solving the problem of deflection and twisting during the adjustment process.

[0033] The adjusting screw 507 serves as the driving source for the lighting adjustment mechanism 5. It rotates through the mounting housing 6 and is rotatably disposed inside the housing 1. The threaded section of the adjusting screw 507 is threaded into the corresponding threaded hole on the transparent cover 504. When the adjusting screw 507 is rotated externally, the threaded engagement converts the rotational motion into the linear motion of the transparent cover 504. The rotation of the adjusting screw 507 drives the transparent cover 504 to move the optical lens 505 to perform stepless height adjustment relative to the lamp bead 502. This allows for preset adjustment from focused light to floodlight according to different installation locations and lighting requirements. The adjustment function can be completed before the lamp is installed on the ceiling.

[0034] To increase the efficiency of light energy utilization, a reflector 503 is also provided on the outside of the lamp bead 502. The reflector 503 is fixedly connected to the inner cavity of the housing 1. The inner surface of the reflector 503 has a high reflectivity, which is used to reflect part of the light emitted by the lamp bead 502 and guide it to the optical lens 505. The reflector 503 and the optical lens 505 together form a complex optical zoom system, which further ensures the beam quality and increases the reflectivity while achieving the effect of energy saving.

[0035] As a preferred embodiment, in order to solve the problem that the lamp is prone to overheating under high power and long-term operation, which affects the life of the components, the heat dissipation mechanism 9 has been specifically optimized in structure. The heat dissipation mechanism 9 includes a small fan 902 set inside the mounting shell 6. The small fan 902 is fixedly connected to the outer wall of the mounting shell 6 by mounting bolts 904. In order to prevent dust in the external environment from entering the lamp with the airflow and adhering to the surface of the components, thus affecting the heat dissipation effect, a dust cover 903 is provided on the air inlet side of the small fan 902. The mounting bolts 904 penetrate through the inside of the dust cover 903, fixing the dust cover 903 to the air inlet side of the small fan 902. The dust cover 903 completely covers the air inlet of the small fan 902 to filter dust in the external cold airflow.

[0036] When cooling of the lamp is required, a small fan 902 installed inside the mounting housing 6 is activated. The small fan 902 blows the external cold air through the dust cover 903 and onto the heat sink 2 integrated on the outside of the housing 1. The cold air exchanges heat with the heat sink 2 and removes heat. The hot air then exits the mounting housing 6 through the heat dissipation hole 901 on the upper side of the mounting housing 6. This active air cooling structure, together with the heat sink 2 on the outer wall of the housing 1, significantly improves the heat dissipation efficiency.

[0037] As a preferred embodiment, in order to achieve quick embedded installation and fixation of the light fixture in the ceiling, a torsion spring 8 is installed on the side wall of the mounting housing 6. The torsion spring 8 is used to fix the light fixture in the ceiling. In use, the torsion spring 8 installed on the side wall of the mounting housing 6 is pulled to retract it. After the light fixture is pushed into the ceiling opening, the torsion spring 8 is released. The elastic restoring force of the torsion spring 8 is used to press the inner wall of the ceiling, thereby achieving stable suspension of the light fixture.

[0038] As a preferred embodiment, in order to improve the convenience and reliability of power connection, a terminal block 3 is fixedly connected to the upper surface of the housing 1, and a terminal block 4 is provided at the top of the housing 1. The terminal block 3 is installed inside the terminal block 4 by a rotating snap-fit ​​method and realizes electrical connection. After receiving power, the terminal block 3 outputs electrical power to the circuit board 501 fixed on the top wall of the inner cavity of the housing 1. The circuit board 501 is used to control the light emission of the LED bead 502 fixed on the lower surface of the circuit board 501. This rotating snap-fit ​​structure avoids the cumbersome traditional screw wiring and improves installation efficiency.

[0039] In a preferred embodiment, in order to further limit the movement trajectory of the transparent cover 504 and prevent it from rotating circumferentially following the adjusting screw 507, the upper end of the limiting post 506 is fixedly connected to the top wall of the inner cavity of the housing 1, and the limiting post 506 is arranged on one side relative to the adjusting screw 507. The limiting post 506 and the adjusting screw 507 are distributed parallel to each other in space, and together they form a double guiding support for the transparent cover 504, ensuring the stability of the vertical lifting of the optical lens 505.

[0040] Working principle: When energy-saving lamps need to be installed, the installer first installs the heat dissipation mechanism 9 on top of the mounting shell 6, and at the same time installs the shell 1 inside the mounting shell 6. Then, the bottom opening of the mounting shell 6 is sealed by the high-transparency glass 7 to complete the internal assembly of the lamp. At this time, by rotating the adjusting screw 507 that passes through the mounting shell 6 and is set inside the shell 1, the rotation of the adjusting screw 507 causes the threaded transparent cover 504 to slide up and down along the limiting post 506 in the inner wall of the shell 1. The sliding of the transparent cover 504 causes the optical lens 505 fixed inside it to adjust its height. The change in the distance between the optical lens 505 and the lamp bead 502 can realize the preset beam angle adjustment from focused light to floodlight.

[0041] After adjustment, the terminal block 3, fixed to the upper surface of housing 1, is rotated and engaged inside the terminal block 4, forming an electrical connection. The terminal block 3 receives power and outputs it to the circuit board 501 fixed to the top wall of the inner cavity of housing 1. The circuit board 501 controls the LED beads 502 fixed to its lower surface to emit light. The light emitted by the LED beads 502 is reflected by the reflector 503 covering the outside of the LED beads 502 and then reaches the optical lens 505, thus achieving the preset beam angle. Simultaneously, by actuating the mounting torsion spring 8 installed on the side wall of the mounting housing 6, the light fixture can be installed and fixed inside the ceiling.

[0042] When the lamp works for a long time, the internal components of the housing 1 will generate high heat. At this time, the small fan 902 of the heat dissipation mechanism 9 is activated to actively cool down the lamp. The small fan 902 blows the external cold air through the dust cover 903 on the air inlet side and then blows it toward the heat sink 2 integrated on the outside of the housing 1. The cold air exchanges heat with the heat sink 2 and removes the heat. Then the hot air is discharged from the mounting housing 6 through the heat dissipation hole 901 on the upper side of the mounting housing 6, thereby effectively extending the service life of the lamp components and maintaining the light efficiency.
