[0034] Ceiling lights, as key lighting fixtures for indoor spaces, are widely used in various residential, commercial, and public spaces due to their simple appearance and efficient lighting performance. Their internal structure mainly consists of two parts: the light panel and the driver. The light source, precisely mounted on the light panel, is responsible for generating light, while the driver plays a crucial role in driving the light panel to emit light. Together, they work to create a bright and comfortable environment for people.

[0035] In the relevant technical field, the connection method between the driver board and the lamp board has significant shortcomings. Currently, the driver board mainly relies on wires to connect to the lamp board, and during installation, it is simply placed on top of the lamp board without any additional structures or parts for auxiliary fixation. During installation, workers may accidentally bump the driver board, causing it to shift on the lamp board. After the lamp is put into use, daily vibrations, such as resonance from operating electrical equipment or slight vibrations from people walking around, can cause the driver board to shake continuously, potentially damaging the delicate electronic components and leading to poor contact. Once poor contact occurs, the lamp will frequently exhibit flickering, failure to light up, and other abnormal phenomena, severely affecting the lighting effect and user experience.

[0036] Therefore, such as Figures 1 to 5As shown, the ceiling light fixture proposed in this utility model includes a lamp sleeve 100 and a lamp holder 200. The lamp sleeve 100 has a regular circular cross-section, and the shape of the lamp holder 200 is adapted to the internal space of the lamp sleeve 100. The lamp sleeve 100 is used for fixed connection to the ceiling, and the lamp holder 200 passes through the lamp sleeve 100, with the lamp holder 200 and the lamp sleeve 100 engaging in a snap-fit ​​fit. Inside the lamp holder 200, there is a lamp board 300 and a driver board 400. The lamp board 300 is provided with multiple light sources 310 and is made of a metal substrate or ceramic substrate with good heat dissipation performance. On the surface of the lamp board 300, multiple light sources 310 are arranged radially at intervals. These light sources 310 are high-efficiency, long-life LED beads, and they are evenly distributed on the lamp board 300 to ensure uniform light output. The driver board 400 is electrically connected to the lamp board 300 and is used to drive the light source 310 to emit light. That is, the driver board 400 is electrically connected to the lamp board 300 via wires, thereby driving the light source 310 to emit light. The driver board 400 is plugged into the lamp board 300. This plug-in structure provides a more secure connection, ensuring the driver board 400 is tightly inserted into the lamp board 300. The connection between the two is more robust and less prone to loosening due to vibration, impact, or other factors. This effectively avoids collisions between the driver board 400 and other components, reducing the risk of damage to the electronic components on the driver board 400. This lowers the probability of flickering or failure to light the lamp due to poor contact, significantly improving the reliability and lifespan of the lamp and providing users with a more stable and reliable lighting experience.

[0037] In some embodiments of this utility model, such as Figures 1 to 3 As shown, the lamp panel 300 is provided with a first slot 320, which extends along the thickness direction of the lamp panel 300. The length and width of the first slot 320 are adapted to the length and width of the driver board 400. The driver board 400 is inserted into the first slot 320, and after the driver board 400 is inserted into the slot, the inner wall of the slot is tightly fitted with the driver board 400. This provides a relatively stable connection, which is not easily loosened due to vibration, collision, or other factors, effectively preventing the driver board 400 from colliding with other components, thereby improving the reliability of the lamp.

[0038] In some embodiments of this utility model, an elastic spring is installed on the lamp plate 300, and a metal piece that can cooperate with the spring is provided on the edge of the drive plate 400. During installation, the metal piece on the edge of the drive plate 400 is tightly clamped by the spring, thereby completing the connection. The elasticity of the spring can buffer vibration to a certain extent. This provides a relatively stable connection, which is not easy to loosen due to vibration, collision, or other factors, effectively preventing the drive plate 400 from colliding with other components, thereby improving the reliability of the lamp.

[0039] In some embodiments of this invention, a plurality of metal pins are provided on the driver board 400, and corresponding pin holders are provided on the lamp board 300. During installation, the pins of the driver board 400 are precisely inserted into the pin holders of the lamp board 300. The tight contact between the pins and the pin holders enables electrical connection between the lamp board 300 and the driver board 400. This insertion method has a large contact area and good conductivity. It provides a relatively stable connection that is not easily loosened by vibration, collision, or other factors, effectively preventing the driver board 400 from colliding with other components, thereby improving the reliability of the lamp.

[0040] In some embodiments of this utility model, such as Figures 1 to 5 As shown, the lamp holder 200 has a protrusion 250 inside. The protrusion 250 is a regular rectangular block, and its length is less than or equal to the diameter of the lamp holder 200. The protrusion 250 protrudes from the inside out and forms a receiving groove inside to accommodate the driver plate 400. This effectively utilizes the external space of the lamp holder 200. The protrusion 250 frees up space inside the lamp holder 200 to install other components, improving the utilization rate of the external space of the lamp holder 200. When the driver plate 400 is placed in the receiving groove, the four walls of the receiving groove can limit the movement of the driver plate 400, greatly reducing the shaking space of the driver plate 400 inside the lamp holder 200. This effectively prevents the driver plate 400 from colliding with other components inside the lamp holder 200 due to vibration, collision, or other factors during lamp installation, use, and transportation.

[0041] In some embodiments of this utility model, such as Figures 1 to 3 As shown, the lamp plate 300 has a circular cross-section, and its diameter is adapted to the diameter of the lamp holder 200 for installation inside the lamp holder 200. A limiting member is provided inside the lamp holder 200 to restrict the movement of the lamp plate 300 along its centerline. One or more limiting members can be provided, and can be flexibly adjusted according to the stability of the lamp plate 300 to ensure its installation stability. When the lamp plate 300 is installed in the lamp holder 200, the protruding part of the limiting member can make tight contact with the edge of the lamp plate 300, thereby restricting its movement. The limiting member effectively ensures that the lamp plate 300 remains in a predetermined position, preventing the movement of the lamp plate 300 from compressing the accommodating space of the drive plate 400, thus avoiding affecting the connection stability between the lamp plate 300 and the drive plate 400, as well as the overall lighting performance of the luminaire.

[0042] In some embodiments of this utility model, such as Figures 1 to 5As shown, the outer peripheral wall of the lamp holder 200 is provided with a lever adjustment mechanism 210. The outer peripheral wall of the lamp holder 200 has a slot, inside which a lever is installed. The lever can move along the outer peripheral wall of the lamp holder 200. The lever adjustment mechanism 210 is electrically connected to the lamp board 300 and is used to switch and adjust the light emission mode of the light source 310. In some application scenarios, as the lever rotates, the conductive contacts on the lever will contact different circuit connection points, thereby changing the current signal output by the driver board 400 to the lamp board 300. For example, when the lever is in the initial position, the circuit connected by the conductive contacts causes the light source 310 on the lamp board 300 to emit light in the normal full-brightness mode. When the user moves the lever upwards by a certain angle, the conductive contacts connect to another set of circuit connection points. The driver board 400 will adjust the output current according to this circuit signal, causing the light source 310 to switch to an energy-saving mode with reduced brightness, or to a warm light tone mode, to meet the user's lighting needs in different scenarios. With this lever adjustment mechanism 210, users can easily switch and adjust the light emission mode of the ceiling light source 310 without the need for an additional remote control or complicated smart devices, greatly improving the convenience and experience of using the ceiling light.

[0043] In some embodiments of this utility model, such as Figure 5 As shown, the lever adjustment mechanism 210 has a first, second, and third setting. The color temperature of the first setting is 3000K. When the lever is in the first setting, the circuit connected to the conductive contacts drives the driver board 400 to output a specific current, and the light source 310 on the lamp board 300 displays a color temperature of 3000K. The light at this color temperature has a warm yellow tint, which can effectively relieve fatigue and help people rest better. The color temperature of the second setting is 4500K. When the lever is moved to the second setting, the conductive contacts are connected to another set of circuit connection points, and the driver board 400 then adjusts the output current to change the color temperature of the light source 310 to 4500K. The light at this setting is neutral white light, combining brightness and softness. The light is uniform and natural, providing just the right lighting effect. It will not cause drowsiness due to excessively warm light, nor will it cause visual fatigue due to excessively cold light. The third setting has a color temperature of 6000K. When the user switches the lever to the third setting, the circuit connected by the conductive contacts changes the current output of the driver board 400, and the color temperature of the light source 310 reaches 6000K. At this time, the light has a cool white tone, high brightness and clarity. This color temperature provides sufficient and shadow-free illumination, making it more convenient and safer for users to operate under the light.

[0044] In some embodiments of this utility model, such as Figures 1 to 5As shown, the lamp sleeve 100 is made of either plastic or aluminum. Aluminum alloy has excellent heat dissipation properties, quickly dissipating heat generated inside the lamp and effectively extending its lifespan. Aluminum's high strength provides better protection for internal components such as the lamp holder 200, lamp board 300, and driver board 400 in the event of an accidental impact, reducing the risk of damage. The lamp sleeve 100 can also be made of engineering plastics with good insulation and high strength. Plastic is lightweight, facilitating installation and transportation, and significantly reducing the difficulty of installation for workers. Simultaneously, the excellent insulation properties of plastic effectively prevent safety hazards caused by electrical leakage, making it suitable for homes and other locations with high electrical safety requirements.

[0045] In some embodiments of this utility model, such as Figure 5 As shown, the outer peripheral wall of the lamp holder 200 is provided with a mounting groove 240, which is distributed in a ring and is a regular rectangular groove. The lamp sleeve 100 has a mounting block 110 inside, which is also made of the same material as the lamp sleeve 100 and is integrally formed with it. The mounting block 110 rotates and engages with the mounting groove 240 to fix the lamp holder 200 to the lamp sleeve 100. To install the lamp holder 200 and lamp sleeve 100, simply insert the lamp holder 200 into the lamp sleeve 100, aligning the mounting block 110 inside the lamp sleeve 100 with the mounting groove 240 on the outer peripheral wall of the lamp holder 200. As the lamp holder 200 rotates further, the mounting block 110 begins to rotate along the inner wall of the mounting groove 240. When the mounting block 110 rotates to a specific position, it engages tightly with the mounting groove 240, thus firmly fixing the lamp holder 200 to the lamp sleeve 100. This rotating snap-fit ​​method is not only easy to operate, requiring only simple insertion and rotation to complete the installation, but also provides a stable connection that can effectively resist external forces caused by vibration, shaking, and other factors during the use of the lamp, ensuring that the lamp holder 200 and the lamp sleeve 100 always maintain a tight connection.

[0046] In some embodiments of this utility model, such as Figures 1 to 5As shown, the lamp holder 200 is provided with a diffuser plate 220, which is made of a material with high light transmittance and diffuse reflection characteristics, such as acrylic. Its main function is to evenly diffuse the light emitted by the light source 310 on the lamp panel 300, avoiding excessive light concentration and the generation of glaring spots, thereby providing a softer and more comfortable lighting effect for the room. The diffuser plate 220 is provided with inverted clips 221, which are spaced apart at the edge of the diffuser plate 220. The inverted clips 221 have a hook-shaped structure and are manufactured with the diffuser plate 220 through an integral molding process to ensure the firm connection of the diffuser plate 220. A second slot 230 is provided on the side of the lamp holder 200 facing the center line. The second slot 230 is distributed in a ring around the center line of the lamp holder 200, and the inverted clips 221 engage with the second slot 230. During installation, the installer aligns the diffuser plate 220 with the lamp holder 200 and gently presses it down, causing the buckles 221 on the edge of the diffuser plate 220 to engage with the second slot 230. As the buckles 221 gradually penetrate the second slot 230, their hooks engage with the inner wall of the slot, thus securing the diffuser plate 220 firmly to the lamp holder 200. This snap-fit ​​method between the buckles 221 and the second slot 230 is simple and quick to install. Furthermore, during the use of the light fixture, it effectively resists external forces caused by vibration and shaking, ensuring that the diffuser plate 220 remains in its predetermined position and stably performs its light diffusion function, providing a strong guarantee for improving the lighting quality of the ceiling light.

[0047] In some embodiments of this utility model, such as Figure 4 As shown, there are multiple inverted clips 221, which are distributed at intervals along the circumference of the diffuser plate 220. The number of inverted clips 221 can be flexibly adjusted according to the actual size of the diffuser plate 220 to adapt to different installation requirements. This ensures that the light fixture can effectively resist external forces caused by vibration, shaking, etc. during use, ensuring that the diffuser plate 220 always remains in the predetermined position and stably performs its light diffusion function, providing a strong guarantee for improving the lighting quality of the ceiling light.

[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
