Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to an intelligent LED surface-mounted downlight. Background Technology

[0002] In the modern lighting field, with the continuous improvement of people's requirements for quality of life and the popularization of smart building and smart home concepts, smart LED lighting products are increasingly favored by the market. Surface-mounted downlights, as a common type of indoor lighting fixture, are widely used in homes, commercial spaces, and office environments due to their concentrated light, good lighting effect, and convenient installation. However, traditional LED surface-mounted downlights face some problems in practical applications that urgently need to be solved. For example, in terms of heat dissipation, LED downlights generate a lot of heat during operation. If this heat cannot be dissipated effectively and in a timely manner, the LED downlight temperature will rise, thus affecting its luminous efficiency, lifespan, and light color quality. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an intelligent LED surface-mounted downlight that solves the technical problem of poor heat dissipation in existing LED downlights.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an intelligent LED surface-mounted downlight, including a cylindrical shell, an optical module installed at the front end of the shell, a human detection probe installed at the center of the head of the optical module, a light source board installed at the rear end of the optical module, a heat-conducting plate installed on the back of the light source board, a rear cover plate installed at the rear end of the shell, an intelligent power supply installed on the inner side of the rear cover plate, and a mounting bracket fixed on the outer side.

[0011] 1. This intelligent LED surface-mounted downlight features a one-piece molded aluminum alloy shell with heat dissipation grooves. The heat generated by the light source board during operation is transferred to the heat dissipation fins inside the shell through a heat-conducting plate. The heat dissipation fins then dissipate the heat through the shell, resulting in excellent heat dissipation. In addition, heat dissipation holes are provided on both the rear and front covers, allowing air to circulate inside the shell, further improving heat dissipation. Compared to traditional LED downlights, this downlight has multiple heat dissipation paths, greatly improving the luminous efficiency, lifespan, and color quality of the LED downlight.

[0012] 2. This intelligent LED surface-mounted downlight, by setting up an optical module, can solve the glare problem and achieve the effect of seeing the light but not the light source.

[0013] 3. This intelligent LED surface-mounted downlight, by being equipped with a human detection sensor, can sense the movement of people nearby, thus achieving the advantage of turning on the light when people are present and turning off the light when people leave.

Detailed Implementation

[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] LED surface-mounted downlights utilize a new type of LED lighting source, an improved product developed from traditional downlights. White LEDs consume only 1 / 10 the energy of incandescent bulbs and 1 / 4 the energy of energy-saving lamps, saving electricity and reducing carbon emissions. They also more realistically reproduce the colors of objects, making illuminated objects vibrant, clear, and natural, providing a better visual effect. Furthermore, their appearance is more aesthetically pleasing and lightweight, maintaining the overall unity and perfection of the building's decoration after installation, without disrupting the original décor.

[0024] Due to the inherent technical limitations of existing technologies, such as poor heat dissipation, please refer to... Figures 1-5 This embodiment provides an intelligent LED surface-mounted downlight, which, compared to traditional LED downlights, features multiple heat dissipation paths and excellent heat dissipation. The downlight includes a cylindrical housing 1, with an optical module 2 mounted at the front end. A human sensor 8 is installed at the center of the head of the optical module 2, and a light source board 3 is mounted at the rear end. A heat-conducting plate 4 is mounted on the back of the light source board 3. A rear cover plate 6 is mounted at the rear end of the housing 1, with an intelligent power supply 5 installed on the inner side and a mounting bracket 7 fixed to the outer side. By rationally arranging the components, such as installing the human sensor 8 at the center of the head of the optical module 2, the accuracy and sensitivity of the sensing can be effectively improved. The orderly installation of components such as the light source board 3, heat-conducting plate 4, and intelligent power supply 5 results in a compact internal structure and high functional integration, facilitating production assembly and subsequent maintenance, and enhancing the stability and reliability of the product. The human sensor 8, through signal acquisition, processing, and control mechanisms, works in conjunction with the microcontroller and intelligent power supply 5 to realize the human sensing and light sensing functions of the intelligent LED surface-mounted downlight, providing users with a more intelligent, energy-saving, and comfortable lighting experience.

[0025] Traditional downlights typically have an aluminum heat sink embedded in a sheet metal casing 1, resulting in poor heat dissipation. To address this issue, the casing 1 is made of a single piece of aluminum alloy, and multiple heat dissipation grooves 11 are provided on the outer wall of the casing 1. The single-piece aluminum alloy material has excellent thermal conductivity, enabling rapid heat transfer. The multiple heat dissipation grooves 11 on the outer wall increase the heat dissipation area, accelerate the heat dissipation rate, effectively reduce the temperature of the LED light source, ensure its stable operation, extend its service life, and improve luminous efficiency and light color quality.

[0026] Traditional downlights suffer from a single and inefficient internal heat dissipation method, which fails to effectively transfer the heat generated by the light source, leading to heat accumulation inside the downlight. To address this issue, multiple heat dissipation fins 12 arranged in a ring array are provided on the inner wall of the outer casing 1. These fins 12 are in contact with the heat-conducting plate 4. The ring array of heat dissipation fins 12 on the inner wall of the outer casing 1 further increases the heat dissipation area and, in contact with the heat-conducting plate 4, can quickly conduct the heat generated by the light source plate 3 to the outer casing 1. The heat is then dissipated into the surrounding environment through the heat dissipation grooves 11 on the outer wall of the outer casing 1, forming a highly efficient heat dissipation channel. This significantly improves heat dissipation efficiency and solves the problem of internal heat accumulation.

[0027] Traditional downlights suffer from poor optical design, resulting in glare that negatively impacts lighting performance and user experience. Furthermore, their uneven light distribution fails to meet specific lighting needs. To address this, the optical module 2 includes a reflector 21 mounted on the front of the housing 1. A ring-shaped front cover 24 is installed at the front of the reflector 21. A transparent glass 22 and a grid plate 23 are installed between the reflector 21 and the front cover 24, with the transparent glass 22 located closer to the reflector 21. The reflector 21 reflects and converges light, guiding it to the area requiring illumination and improving light utilization. The transparent glass 22 filters and refracts light, making it softer. The grid plate 23 blocks glare from large angles. These three elements work together to effectively solve the glare problem, achieving a "light without glare" effect while ensuring more uniform light distribution to meet the lighting needs of different scenarios.

[0028] Traditional downlights lack human body sensing functionality and suffer from high energy consumption. To address this issue, a sensor mounting slot 231 for accommodating a human body sensor 8 is provided at the center of the front of the grid plate 23. Furthermore, two sensor cable channels 232 are located on either side of the sensor mounting slot 231 on the front of the grid plate 23. The sensor mounting slot 231 on the grid plate 23 provides a precise installation position for the human body sensor 8, ensuring normal operation and sensing performance. The sensor cable channels 232 neatly arrange the sensor cables, making the internal wiring more standardized and aesthetically pleasing, while reducing interference from cables to other components and improving the overall reliability of the product.

[0029] Traditional downlights have shortcomings in overall heat dissipation design. Relying solely on the outer casing 1 for heat dissipation cannot meet the requirements for efficient heat dissipation, and heat is easily retained inside the downlight. To address this issue, heat dissipation holes are provided on both the rear cover 6 and the front cover 24. The heat dissipation holes on the rear cover 6 and the front cover 24 increase the air circulation channel, which helps the hot air inside the downlight to exchange with the cold air outside, accelerates heat dissipation, further improves the heat dissipation performance of the downlight, ensures that the internal components work in a suitable temperature environment, and extends the service life of the downlight.
