Description

Technical Field

[0001] This invention relates to the field of lighting equipment technology, and in particular to a high-power ceiling spotlight. Background Technology

[0002] In the context of energy conservation and environmental protection, LED lighting fixtures are increasingly used in residential and commercial lighting due to their high light output efficiency and good light focusing performance. Ceiling lighting is an important type of lighting in both homes and businesses, and spotlights are a common type of ceiling lighting. When high-power, high-density light output is required, heat dissipation becomes a problem. Generally, aluminum alloy bases are used to increase heat dissipation, and cooling fins are often added to the base to further improve the cooling effect. However, with the improvement of living standards, the requirements for the shape of lighting fixtures are also increasing, further miniaturization while maintaining high-power, high-density light output is needed. This requires further improvement in heat dissipation. Spotlights are also frequently used in situations requiring various angular lighting. Most of the time, multiple joints are needed to achieve 360° rotation, but this not only results in a complex structure and a large assembly volume, but is also unsightly when exposed.

[0003] In conclusion, it is crucial to obtain a spotlight that offers excellent heat dissipation, easy rotation, and an attractive appearance. Summary of the Invention

[0029] The following detailed description of specific embodiments of the present invention is based on the accompanying drawings. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0030] like Figures 1-5 As shown, the high-power ceiling spotlight of this embodiment includes a lamp holder 100 with a mounting surface 101, a fixing base 200 connected to the lamp holder 100, a light source chip 300 disposed on the mounting surface 101, and an optical component 400 disposed in the light emission direction of the light source chip 300.

[0031] The lamp holder 100 is used to support and install other components, the mounting base 200 is used to connect to the external ceiling, the lamp holder 100 is connected to the mounting base 200, the light source chip 300 is used to emit light, in this embodiment, an LED chip is used, and the optical component 400 is used to adjust the light of the light source chip 300.

[0032] In this embodiment, the lamp holder 100 includes a heat sink 102 and an annular rotating seat 103. The heat sink 102 has the mounting surface 101 and is generally made of metal, such as aluminum alloy, for easy heat dissipation. The annular rotating seat 103 is fixedly connected to the heat sink 102, and its outer wall is spherical and gradually tapers from the center to both sides. The fixing seat 200 is cylindrical and includes a front mounting part 201 and a rear pressure cover 202. The front mounting part 201 has a front spherical mounting groove 2011 that matches the annular rotating seat 103 on the side near the lamp holder 100. The inner side of the rear pressure cover 202 has a rear spherical mounting groove 2021 that matches the annular rotating seat 103. The rear pressure cover 202 is fixedly connected to the front mounting part 201 to fix the annular rotating seat 103 between the front spherical mounting groove 2011 and the rear spherical mounting groove 2021, so that it can rotate in all directions. Using a 360-degree rotation method without dead angles reduces the illumination dead angle and makes dimming more convenient. The lamp holder 100 with the above structure can rotate in all directions to achieve lighting from different angles. It is flexible in rotation, small in size, and aesthetically pleasing.

[0033] The outer wall of the mounting base 200 has mounting ears 203 for fixing to the ceiling. The rear pressure cover 202 is connected to the front mounting part 201 by screws 204.

[0034] To facilitate the positioning of the lamp holder 100, in this embodiment, an O-ring 500 is provided between the annular rotating seat 103 and the front spherical mounting groove 2011 to provide damping. Of course, other elastic materials can be used instead, or mechanical locking positioning can be used.

[0035] There are many ways to connect components. In this embodiment, the annular rotating seat 103 is threadedly connected to the heat sink 102. Threaded connections provide a tighter fit, a larger contact area, and are more conducive to heat conduction and dissipation.

[0036] To improve light efficiency, in this embodiment, the optical component 400 includes a condenser lens 401 disposed in the annular rotating seat 103. The side of the condenser lens 401 away from the mounting surface 101 is connected to the inner wall of the annular rotating seat 103, and an inner cavity 104 is formed between the side wall of the condenser lens 401, the mounting surface 101, and the inner wall of the annular rotating seat 103. The condenser lens 401 adopts a conventional condenser lens, with a side wall that is a total reflection surface, and an overall shape that is larger in the front and smaller in the back. When the side of the condenser lens 401 away from the mounting surface 101 is connected to the inner wall of the annular rotating seat 103, the inner cavity 104 is formed on the rear side. In this embodiment, the condenser lens 401 has a fixing cover 4011 with a similar shape to the condenser lens 401. The inner cavity 104 is defined by the fixing cover 4011.

[0037] To improve heat dissipation, the annular rotating seat 103 has a first through hole 1031 communicating with the inner cavity 104 on the side away from the mounting surface 101, and the radiator 102 has a second through hole 1041 communicating with the inner cavity 104 from its back. This arrangement allows air in front of the condenser lens 401 and air behind the radiator 102 to pass through the inner cavity 104, thereby accelerating heat convection and improving heat dissipation. Furthermore, the back of the radiator 102 has multiple heat dissipation ribs 1021, with a first heat dissipation channel 1022 between the ribs, and the second through hole 1041 communicating with the first heat dissipation channel 1022. Increasing the heat dissipation ribs 1021 and the first heat dissipation channel 1022 increases the heat dissipation area and enhances convection, further improving heat dissipation. More preferably, the outer periphery of the heat dissipation ribs 1021 has a baffle 1023 that closes the first heat dissipation channel 1022.

[0038] To further improve heat dissipation, the outer periphery of the baffle 1023 also has an annular second heat dissipation channel 1024, in which multiple baffles 1025 are arranged at annular intervals. This increases the heat dissipation area and enhances air convection behind the annular rotating seat 103. Furthermore, the baffles 1025 are divided into front baffles 1026 and rear baffles 1027, with more front baffles 1026 than rear baffles 1027. The greater number of front baffles 1026 results in a smaller channel and a higher flow rate, allowing for faster heat dissipation.

[0039] To reduce glare, the optical assembly 400 also includes a reflector 402 mounted on the front mounting portion 201 and located on the annular rotating seat 103. For ease of installation, the front mounting portion 201 is provided with a retaining ring 4021, which has a locking structure for mounting the reflector 402. This combination of lens cross-beams and a reflector achieves high anti-glare performance, reducing glare and making spatial lighting more comfortable.

[0040] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions or improvements within the spirit of the present invention are covered within the scope of the claims of the present invention.
