Description

Technical Field

[0001] This invention relates to the field of lighting technology, specifically to a high-efficiency and energy-saving electric lighting device. Background Technology

[0002] With the continuous development of society and the growing awareness of energy conservation and environmental protection, high-efficiency and energy-saving electric lighting equipment has gradually become the mainstream in the market. This type of equipment not only effectively reduces energy consumption and carbon emissions, but also provides high-quality lighting effects, meeting the lighting needs of various occasions.

[0003] The design principles of high-efficiency and energy-saving electric lighting equipment are mainly based on LED (Light Emitting Diode) technology and photovoltaic power generation technology. LEDs are semiconductor light-emitting devices with characteristics such as high luminous efficiency, long lifespan, and low energy consumption. Through effective current-driven technology, LED light sources can provide stable and uniform illumination, which is the foundation for achieving high-efficiency and energy-saving lighting.

[0004] Photovoltaic power generation technology is primarily based on the photovoltaic effect. When light shines on a solar cell, it is absorbed at the interface layer. Photons with sufficient energy can excite electrons from covalent bonds in P-type and N-type silicon, generating electron-hole pairs. Before recombination, these electrons and holes are separated by the electric field of space charges, forming a current. Through charge separation at the interface layer, a measurable outward voltage is generated between the P- and N-regions. Electrodes can then be added to both sides of the silicon wafer and a voltmeter connected to them, thus outputting electrical energy.

[0005] Combining photovoltaic (PV) power generation technology with LED (light-emitting diode) technology can achieve more efficient and energy-saving lighting. However, in practical applications, the size of PV devices is often strictly limited by the available space, especially when designing compact lighting fixtures, where the area of ​​PV cells becomes very limited, directly restricting the amount of electricity they can generate. Despite continuous advancements in PV technology and improvements in conversion efficiency, it remains difficult to meet the power requirements of LED lighting under low-light conditions.

[0006] Furthermore, the lighting range and energy consumption of LEDs also pose a significant challenge in the integration process. The lighting range of an LED is affected by its emission angle and brightness, and in practical applications, it is not easy to precisely adjust the lighting range of an LED according to ambient lighting conditions and user needs. At the same time, although LEDs themselves have low power consumption, pursuing high-brightness lighting may require increasing the number of LEDs or increasing the drive current, thereby increasing energy consumption, which contradicts the goal of energy conservation.

[0007] Therefore, it is necessary to provide a highly efficient and energy-saving electric lighting device to solve the above problems. Summary of the Invention

[0038] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.

[0039] Example: Please refer to Figures 1-5 In this embodiment of the invention, a high-efficiency and energy-saving electric lighting device is provided, comprising:

[0040] The lamp post 1 has a side bracket 2 fixed to its top;

[0041] The power generation component 3 is mounted on the side frame 2;

[0042] Lighting component 5, which is connected to the lower part of the power generation component 3 by a connecting rod 4, includes:

[0043] The top plate 51 is fixed below the connecting rod 4, and a light-emitting diode 56 is provided at the bottom of the top plate 51;

[0044] Two symmetrically arranged first side plates 52 are respectively rotatably mounted on the left and right sides of the top plate 51 by means of a rotating shaft 57;

[0045] Two symmetrically arranged take-up and release wheels 53 are fixed to the top of the top plate 51. The take-up and release wheels take up and release the first side plate 52 through the rope.

[0046] The rotation of the take-up and release wheel 53 tightens or loosens the rope, thereby driving the first side plate 52 to rotate around the pivot 57. When it is necessary to adjust the lighting range, the rotation of the first side plate 52 can be controlled by the take-up and release wheel 53 and the rope. In other words, the first side plate 52 can be adjusted under different times or weather conditions to optimize the lighting effect.

[0047] In addition, the power generation component 3 can provide power to the lighting component 5. After receiving power, the light-emitting diode 56 starts to emit light to provide illumination. As a lighting source, the light-emitting diode 56 has the advantages of low power consumption, high brightness, and long life, which significantly improves lighting efficiency and reduces energy consumption. Furthermore, the power generation component 3 uses renewable energy to generate electricity, which further reduces operating costs and environmental impact.

[0048] In this embodiment, the top plate 51 is fixed with second side plates 54 on both the front and rear sides, and the vertical line connecting the two second side plates 54 tends to be perpendicular to the direction of the sidewalk.

[0049] It should be explained that this electric lighting equipment can be used for pedestrian lighting. Given that pedestrian walkways are usually narrow, the second side plate 54 of the equipment is fixedly installed.

[0050] This design aims to improve lighting efficiency by optimizing light distribution. Specifically, the virtual vertical line between the two second side panels 54 is set to be approximately perpendicular to the direction of the sidewalk. "Approaching perpendicular" here means that, although there may be slight deviations in reality due to minor bends or inclinations of the sidewalk, the design goal is to ensure that this line is as perpendicular as possible to the sidewalk within the local area where the lighting components are located, thereby maximizing the illumination of the entire width of the sidewalk. This layout not only ensures a safe field of vision for pedestrians on the sidewalk but also effectively avoids wasted light, resulting in both uniform and efficient lighting.

[0051] In this embodiment, the front and rear sides of the first side plate 52 are connected to the third side plate 55, which is used to reduce the light leakage between the first side plate 52 and the second side plate 54 when the first side plate 52 moves closer to the second side plate 54.

[0052] The bottom surfaces of the first side plate 52, the second side plate 54, and the third side plate 55 are all light-concentrating surfaces.

[0053] In addition, the power generation component 3 includes:

[0054] The base frame 31 is fixedly connected to the side frame 2;

[0055] Mounting frame 32, which is rotatably mounted on the base frame 31;

[0056] The first photovoltaic panel 33 is installed on the upper part of the mounting frame 32, with the side of the first photovoltaic panel 33 that receives the light source facing upwards;

[0057] The second photovoltaic panel 34 is installed at the lower part of the mounting frame 32, with the side of the second photovoltaic panel 34 that receives the light source facing downwards;

[0058] The upper surfaces of the top plate 51, the first side plate 52, and the third side plate 55 are all reflective surfaces.

[0059] In other words, the top plate 51, the first side plate 52, and the third side plate 55 can also provide light to the second photovoltaic panel 34 through reflection, and participate in the guidance and reflection of light during the day to a certain extent, further improving the light energy utilization efficiency of the entire power generation component 3 and achieving more efficient power generation. In addition, the first side plate 52 and the second side plate 54 also provide light range limitation for the light-emitting diode 56 to prevent excessive light diffusion.

[0060] Of course, the power generation component 3 also includes equipment such as batteries, which will not be described in detail here.

[0061] Furthermore, the lamp post 1 is also integrated with a controller, which can acquire current time information and adjust the tilt angle of the first side plate 52 according to the current time information.

[0062] In this embodiment, an adjusting rod 35 is also fixed on the base frame 31. A sliding sleeve is slidably disposed on the adjusting rod 35. The sliding sleeve is fastened to the adjusting rod 35 with a locking screw. A hinge rod 36 is hinged between the sliding sleeve and the mounting frame 32.

[0063] Therefore, when installing the power generation component 3, the deflection angle of the mounting frame 32 can be adjusted by adjusting the position of the sliding sleeve, and then the sliding sleeve can be tightened by tightening the locking screw.

[0064] In this embodiment, the top plate 51 is provided with a shaft hole for rotatably connecting the rotating shaft 57. The inner wall of the shaft hole is provided with a plurality of circumferentially spaced sliding grooves 513. A second wedge block 512 is slidably connected in the sliding groove 513. An elastic element 511 is connected between the second wedge block 512 and the sliding groove 513.

[0065] The rotating shaft 57 is externally fixed with a plurality of first wedges 571 corresponding to the second wedge 512.

[0066] In addition, the elastic element 511 is made of a slow-rebound material;

[0067] The first wedge 571 and the second wedge 512 are configured such that when the shaft 57 rotates to lower the first side plate 52, the first wedge 571 is restrained by the second wedge 512.

[0068] Among them, slow rebound material is a special material whose molecular structure causes it to flow and deform when subjected to external pressure. When the external force is removed, it will slowly return to its original shape. A typical example of slow rebound material is polyurethane slow rebound foam, also known as memory foam.

[0069] by Figure 5 For example, in the figure, the first wedge 571 is restricted by the second wedge 512, which enables the first side plate 52 to be positioned without the power of the take-up and release wheel 53, preventing the first side plate 52 from deflecting arbitrarily. When the first side plate 52 needs to be lowered, the take-up and release wheel 53 drives the rotating shaft 57 to rotate clockwise so that the first side plate 52 is lifted. At this time, the second wedge 512 is pushed by the first wedge 571 and stored in the slide groove 513. Then, since the elastic element 511 is made of slow rebound material, the elastic element 511 is temporarily stored in the slide groove 513. At this time, the take-up and release wheel 53 releases the rope, and the rotating shaft 57 can smoothly rotate counterclockwise so that the first side plate 52 is lowered.

[0070] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
