[0029] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0030] Please refer to Figures 1 to 4 , a ceiling lamp, comprising a lamp housing 1, a free-form surface lens 2, a light source component 3 and a power supply component 4;

[0031] The lamp housing 1 is provided with a light source accommodating chamber 5 and a power source accommodating chamber 6, the light source component 3 is located in the light source accommodating chamber 5, the power source component 4 is located in the power source accommodating chamber 6, and the light source component 3 is electrically connected to the power source component 4;

[0032] The surface of the lamp housing 1 is provided with a light outlet connected to the light source accommodating cavity 5, the free-form surface lens 2 is fixed at the light outlet via an adjustable connector 16, and a heat dissipation structure is provided on the side of the lamp housing 1 away from the light outlet.

[0033] From the above description, it can be seen that the beneficial effects of the utility model are: by setting the light source accommodating cavity 5 and the power supply accommodating cavity 6, the light source component 3 and the power supply component 4 are processed inside, and a heat dissipation structure is set outside the lamp housing 1 to improve the compactness of the lamp structure. At the same time, a free-form surface lens 2 is set at the light outlet, and the installation angle of the free-form surface lens 2 can be adjusted through the adjustable connecting part 16, etc. Combined with the optical characteristics of the free-form surface lens 2 itself, the propagation direction of the light emitted by the light source component 3 can be freely adjusted, and the assembly is simple and the operation is convenient.

[0034] Furthermore, it also includes a sensor interface 8;

[0035] The sensor interface 8 is disposed on a surface of the free-form surface lens 2 away from the light source assembly 3 , and the sensor interface 8 is electrically connected to the light source assembly 3 .

[0036] From the above description, it can be known that by setting the sensor interface 8, some sensors, such as infrared / microwave sensors, etc., can be matched and connected, so that functions such as color adjustment and power adjustment can be configured.

[0037] Furthermore, a mounting groove 9 is provided at the center of a side of the free-form surface lens 2 away from the light source assembly 3 , and the sensor interface 8 is arranged on the mounting groove 9 .

[0038] From the above description, it can be seen that when in use, the heat emitted by the light source assembly 3 will accumulate inside the free-form surface lens 2, so a mounting groove 9 is provided at the center to prevent the thermal expansion effect from causing the assembly relationship between the light source assembly 3 and the free-form surface lens 2 to be destroyed and thus affect the light distribution.

[0039] Furthermore, a protective cover 10 is provided on the sensor interface 8 .

[0040] It can be seen from the above description that by providing the protective cover 10 , the sensor interface 8 is provided with waterproof and dustproof protection to prevent the sensor interface 8 from being damaged.

[0041] Furthermore, it also includes a manual switch 11, and the manual switch 11 is electrically connected to the light source assembly 3.

[0042] It can be seen from the above description that the manual switch 11 is provided to be used for manually adjusting the brightness of the lamp, etc.

[0043] Furthermore, the light source assembly 3 includes a substrate 31 and a light source 32;

[0044] The substrate 31 is disposed in the light source accommodating cavity 5 , and the surface of the substrate 31 is disposed toward the light outlet. At least two light sources 32 are distributed in an array on the surface of the substrate 31 .

[0045] From the above description, it can be seen that the light sources 32 are distributed in an array on the surface of the substrate 31 so as to correspond to the focal points of the free-form surface lens 2 to enhance the lighting effect.

[0046] Furthermore, a waterproof joint 12 is provided on the lamp housing 1;

[0047] The waterproof connector 12 is electrically connected to the power supply assembly 4 .

[0048] As can be seen from the above description, the provided waterproof connector 12 ensures that the power supply assembly 4 is stably connected to the external power supply to ensure power supply.

[0049] Furthermore, it also includes a flexible filling member 13;

[0050] The flexible filling member 13 is sandwiched between the edge of the free-form surface lens 2 and the opening edge of the light outlet.

[0051] It can be seen from the above description that by providing the flexible filling member 13 , the air tightness between the free-form surface lens 2 and the lamp housing 1 is improved, while deformation damage to the free-form surface lens 2 caused by thermal expansion is reduced.

[0052] Furthermore, a mounting bracket 14 is provided on the lamp housing 1 .

[0053] It can be seen from the above description that the installation bracket 14 is provided to facilitate fixing the lamp in the application scene.

[0054] Furthermore, the heat dissipation structure includes heat sinks 7 , and at least two heat sinks 7 are distributed on a surface of the lamp housing 1 away from the light outlet.

[0055] It can be seen from the above description that rapid heat dissipation is achieved by using a plurality of heat sinks 7 without coating glue or the like on the substrate 31 .

[0056] Please refer to 1 to Figure 4 , Embodiment 1 of the present utility model is:

[0057] A ceiling lamp includes a lamp housing 1, a free-form surface lens 2, a light source component 3 and a power supply component 4; a light source accommodating chamber 5 and a power supply accommodating chamber 6 are provided in the lamp housing 1, the light source component 3 is located in the light source accommodating chamber 5, the power supply component 4 is located in the power supply accommodating chamber 6, and the light source component 3 is electrically connected to the power supply component 4; a light outlet connected to the light source accommodating chamber 5 is provided on the surface of the lamp housing 1, the power supply accommodating chamber 6 is located on the side of the light source accommodating chamber 5 away from the light outlet, the free-form surface lens 2 is fixed at the light outlet through an adjustable connector 16, and a heat dissipation structure is provided on the side of the lamp housing 1 away from the light outlet. The power supply component 4 is heat-dissipated by potting glue, and then is placed in the power supply accommodating chamber 6 by locking, which is convenient for assembly.

[0058] In this embodiment, if Figure 4 As shown, the light source assembly 3 includes a substrate 31 and a light source 32; the substrate 31 is arranged in the light source accommodating cavity 5, and the board surface of the substrate 31 is arranged toward the light outlet, and at least two light sources 32 are arranged in an array on the board surface of the substrate 31. The heat dissipation structure specifically includes heat sinks 7, and a plurality of heat sinks 7 are arranged in parallel on the lamp housing 1. With the design of a plurality of heat sinks 7, the back of the substrate 31 does not need to be coated with thermal conductive glue to ensure the heat dissipation of the substrate 31, which can save the cost of thermal conductive glue and simplify the process. Among them, the light sources 32 are arranged in a densely stacked form, and the center point of the arrangement corresponds to the focus of the free-form surface lens 2. The color of the light source 32 can be any color temperature of 2000-7000K or any combination of two thereof, such as 3000K and 5000K. The specific color selection shall be based on the actual application requirements, and the color temperature switching or color mixing function can be realized.

[0059] And, if Figure 1 and Figure 2As shown, the power supply accommodating chamber 6 is provided on the back of the lamp housing 1 and is opened upward; this structural design is also easy to assemble, and a stable connection effect can be obtained by simply fitting the power supply assembly 4 to the lamp housing 1, and the operation is simple, convenient and fast. Reasonable structural design can save space while ensuring the compact consistency of the structure. A waterproof connector 12 is provided on the lamp housing 1; the waterproof connector 12 is electrically connected to the power supply assembly 4.

[0060] In this embodiment, if Figure 2 and Figure 3 As shown, the adjustable connecting member 16 can specifically use a step screw, and the free-form surface lens 2 adopts a symmetrical circular light distribution structure. Relying on the design of the free-form surface lens 2, the light-emitting angle of the free-form surface lens 2 can be adjusted in combination with the step screw, so as to realize the switching of 60° and 90° on a lamp body. This function can reduce the stock specifications and also save the lens mold cost. It is particularly low, and the step screw is preferably a 304 stainless steel shoulder semi-thread equal height limit bolt. Accordingly, the fixing structure of the free-form surface lens 2 is a structure designed to match the step. A boss is provided above the free-form surface lens 2, and there are N and W marks next to it. N represents narrow light distribution, that is, 60°, and W represents wide light distribution, that is, 90°. If the angle function is required, it can be directly rotated or adjusted by loosening the screw.

[0061] In addition, Figure 2 As shown, the gap between the edge of the free-form surface lens 2 and the opening edge of the light outlet is also filled with a flexible filling member 13. The flexible filling member 13 can be a foamed silicone ring, which relies on the elastic deformation of the foamed silicone ring to fill the fine gap between the sealing interfaces and block the leakage channel to achieve sealing. In reality, poor waterproofing is often caused by factors such as the poor flatness and surface roughness of the lamp housing, the insufficient strength of the free-form surface lens 2 to deform under force, and the insufficient compression of the rubber ring to fill the gap. Therefore, foamed silicone material is particularly used as a sealing material because it has excellent heat insulation, waterproof, shockproof and other properties. The foaming principle is mainly achieved through chemical reactions. Bubbles are formed by mixing the base liquid and the foaming agent, so that the silicone expands to form foamed silicone. Foamed silicone can be used for a long time and can maintain its soft and elastic properties. It is environmentally friendly and non-toxic, has excellent chemical stability, weather aging resistance, non-corrosiveness, low linear shrinkage, and easy operation.

[0062] In this embodiment, a mounting bracket 14 is provided on the lamp housing 1, and the mounting bracket 14 can adopt a gantry-type mounting structure; in addition, a mounting ring 15 can be provided on the back of the lamp housing 1 to provide a variety of fixing methods.

[0063] Please refer to Figure 2 and Figure 3 , Embodiment 2 of the present utility model is:

[0064] A ceiling lamp, based on the above-mentioned embodiment 1, further includes a sensor interface 8 and a manual switch 11, and the sensor interface 8 and the manual switch 11 are electrically connected to the light source assembly 3. A mounting groove 9 is provided at the center of a side of the free-form surface lens 2 away from the light source assembly 3, and the sensor interface 8 is provided on the mounting groove 9. In addition, a protective cover 10 is provided on the sensor interface 8.

[0065] In this embodiment, the middle area of ​​the free-form surface lens 2 is set as a sensor interface 8 and a manual switch 11, which can match infrared / microwave sensors and configure power adjustment and color temperature adjustment functions according to needs; in addition, because the lamp is a high-power product, the heat generated by the light source 32 during operation will gather inside the lens. By setting the mounting groove 9, it can also prevent the thermal expansion effect from causing the assembly relationship between the light source 32 and the lens to be destroyed, thereby affecting the light distribution. In particular, the materials of the free-form surface lens 2 include PC (polyester), PMMA (polymethyl methacrylate), PS (polystyrene), PEI (polyether imide) and any two or more of these composite materials. Diffusion materials can also be added to the above materials to further meet different optical requirements.

[0066] In summary, the present invention provides a ceiling lamp, which arranges a light source accommodating cavity and a power supply accommodating cavity, and internally processes the light source component and the power supply component. A heat dissipation structure is arranged outside the lamp housing to improve the compactness of the lamp structure. At the same time, a free-form surface lens is arranged at the light outlet, and the installation angle of the free-form surface lens can be adjusted by an adjustable connecting piece, etc., and combined with the optical properties of the free-form surface lens itself, the propagation direction of the light emitted by the light source component can be freely adjusted, and the assembly is simple and the operation is convenient; a substrate with a plurality of light sources distributed in an array is arranged in the light source accommodating cavity, which cooperates with the free-form surface lens to enhance the lighting effect, and the operating stability of the lamp is improved by arranging a waterproof joint and a flexible filling piece; and a variety of installation methods such as mounting brackets and mounting rings are also provided.
