[0034] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0035] Embodiment 1

[0036] Reference Figures 1 to 5 As shown, an LED lighting module 100 provided in this embodiment includes a light source module and a top cover 20, wherein the light source module includes a substrate 10, a driving circuit 40 and an LED light-emitting component 30. Specifically, the substrate 10 is a metal-based printed circuit board (MCPCB), such as an aluminum substrate of a printed circuit board, etc. The substrate 10 has a central packaging area and a peripheral packaging area located outside the central packaging area. The driving circuit 40 is packaged in the central packaging area of ​​the substrate 10, and the LED light-emitting component 30 is packaged in a ring shape in the peripheral packaging area of ​​the substrate 10 and is electrically connected to the driving circuit 40. Figure 5As shown, the various components of the driving circuit 40 (including the LED driver 41 and the adjustment unit 42) are centrally packaged in the middle packaging area of ​​the substrate 10, and the LED light-emitting assembly 30 is a plurality of lamp beads, and the plurality of lamp beads surround the periphery of the driving circuit 40 to form an annular light source. The plurality of lamp beads can be single-color lamp beads or multi-color lamp beads. In this embodiment, multi-color lamp beads are used to adjust the color temperature. Specifically, the plurality of lamp beads are arranged into three discontinuous arc segments, which is equivalent to the annular light source having three gaps to facilitate subsequent assembly.

[0037] The substrate 10 is embedded and fixedly covered on the bottom of the top cover 20. The top cover 20 has a receiving cavity 21 corresponding to the middle packaging area of ​​the substrate 10 and a curved lens 22 corresponding to the peripheral packaging area of ​​the substrate 10 and having a semi-tube-shaped cross section. The driving circuit 40 is accommodated in the receiving cavity 21 of the top cover 20, and the LED light-emitting assembly 30 is accommodated in the curved lens 22 of the top cover 20. Specifically, there are three curved lenses 22, which correspond to three sections of light sources respectively; the light emitted by multiple lamp beads of each section of the light source is concentrated in one curved lens 22, and then emitted through the curved lens 22; the emitted light is uniform.

[0038] With this arrangement, the drive circuit 40 is packaged in the middle packaging area of ​​the substrate, and the LED light-emitting component 30 is packaged in a ring shape in the peripheral packaging area of ​​the substrate 10; the middle drive circuit 40 will not block the light irradiated to the outside by the LED light-emitting component 30, and will not affect the lighting.

[0039] The top cover 20 integrates a receiving cavity 21 and a curved lens 22. The receiving cavity 21 is used to receive the driving circuit 40. The LED light-emitting assembly 30 is received in the curved lens 22 of the top cover 20, so that the light of the LED light-emitting assembly 30 is uniformly injected into the lens 22 and then emitted, and the emitted light is uniform. Specifically, the surface of the curved lens 22 also has scattering patterns, which can better scatter the emitted light, realize wide-angle lighting by light scattering, and achieve better uniformity of the emitted light.

[0040] In this embodiment, the driving circuit 40 includes an LED driver 41 and an adjustment unit 42 connected to the LED driver 41, and the adjustment unit 42 is a color temperature regulator for adjusting the color temperature and a power regulator for adjusting the power. In this way, the current of the LED light-emitting component 30 can be adjusted according to actual needs to control the color temperature and power; the function is more comprehensive and the applicability is wider. Of course, the adjustment unit 42 can also select a color temperature regulator for adjusting the color temperature alone, or select a power regulator for adjusting the power alone.

[0041] Specifically, the adjustment unit 42 is a mechanical multi-gear adjustment unit with a gear lever, such as a color temperature regulator having a gear lever for switching different color temperatures, and a power regulator having a gear lever for switching different powers; the function switching is achieved by manually operating the gear lever of the corresponding regulator. The top cover 20 is provided with a clearance opening 29, and the gear lever of the adjustment unit 42 is located in the clearance opening 29 of the top cover 20, which is convenient for manual operation. At the same time, the surface of the top cover 20 is engraved with parameter marks, so that the operator can intuitively confirm the parameters.

[0042] Specifically, the connection relationship and control method between the LED driver 41 and the above-mentioned adjustment unit 42 are all existing technologies, which have been mastered and implemented by technicians in this field, and will not be described in detail here. Of course, in other embodiments, different adjustment units 42 can be designed according to actual needs, such as only designing a color temperature regulator or only designing a power regulator, etc.; or replacing the mechanical multi-speed adjustment unit with an electronically controlled automatic adjustment unit, or not using the adjustment unit 42, etc.

[0043] The substrate 10 is provided with a plurality of first mounting holes 11, specifically two, and the top cover 20 is provided with a second mounting hole 23 corresponding to the first mounting hole 11, and also includes a fastener, which is passed through the corresponding first mounting hole 11 and the second mounting hole 23 and fixes the substrate 10 and the top cover 20; in this way, the substrate 10 and the top cover 20 are fixedly installed. Specifically, the fastener can be installed by fastening screws, strong magnetic clips or magnetic screws in the prior art. When a fastener with magnetic force, such as a strong magnetic clip or a magnetic screw, is used, it can be fixed to the base of a suitable lamp by magnetic attraction later.

[0044] The peripheral packaging area of ​​the substrate 10 is also packaged with a power connector 50. Specifically, the power connector 50 is packaged between two adjacent light sources. The power connector 50 is used to connect to an external power source and the drive circuit 40. The top cover 20 has a peripheral accommodating cavity 24 corresponding to the power connector 50. The power connector 50 is assembled in the peripheral accommodating cavity 24 of the top cover 20 to cover and protect the power connector 50. The wiring terminal of the power connector 50 is exposed on the surface of the top cover 20 to facilitate external circuit connection.

[0045] The base plate 10 and the top cover 20 are provided with corresponding threading holes (i.e., the threading holes 13 of the base plate 10 and the threading holes 26 of the top cover 20); specifically, the threading holes 13 and 26 are provided in the central area, so that the power cord can pass through the threading holes 13 and 26 in the central area and be connected to the power connector 50, so as to meet the assembly requirements of some lamps that require the power cord to pass through the center. Of course, in other embodiments, the structure of the threading holes 13 and 26 may not be adopted, or the base plate 10 may not encapsulate the power connector 50. When the base plate 10 does not encapsulate the power connector 50, the power connection line of the drive circuit 40 can be directly extended and connected to the outside of the LED lighting module 100.

[0046] The peripheral packaging area of ​​the substrate 10 has multiple blank areas 12 without packaged devices, and in this embodiment, there are two blank areas 12. The top cover 20 is provided with a wire clamp 25 on the surface corresponding to the blank area 12. In this way, the wire clamp 25 can clamp and fix the cables connected from the threading holes 13 and 26 to prevent the cables from being misplaced and resting on the surface of the lens 22, thereby affecting the lighting.

[0047] In this embodiment, the LED light emitting assembly 30 is divided into three arc-shaped segments at intervals, and the interval area is used to make way. Of course, in other embodiments, if the electrical connection wires and other cables do not pass through the surface of the top cover 20, the LED light emitting assembly 30 can also be a continuous and complete annular light source.

[0048] Specifically, Figure 4 As shown, the hole wall of the second mounting hole 23 of the top cover 20 extends into the first mounting hole 11 of the substrate 10, and the hole wall of the threading hole 26 of the top cover 20 is arranged in the threading hole 13 of the substrate 10; such a configuration can better protect the device located between the top cover 20 and the substrate 10. At the same time, the hole wall of the second mounting hole 23 extending into the first mounting hole 11 is flush with the bottom of the substrate 10, and the hole wall of the threading hole 26 of the top cover 20 extending into the threading hole 13 is flush with the bottom of the substrate 10; there will be no restriction on the bottom of the substrate 10, and it can better adapt to more installation methods.

[0049] The LED lighting module provided in this embodiment, when not assembled on a finished lamp, is tested as a ceiling lamp with parameters, and its vertical lighting angle is about 130°, and its lighting coverage pattern is circular.

[0050] Continue to refer to Figure 6 and Figure 7As shown, this embodiment also provides an LED lamp, including a base 200 and an LED lighting module, wherein the base 200 is equipped with a heat sink 210, wherein the LED lighting module is the LED lighting module 100 described above, and the LED lighting module 100 is assembled on the base 200, and the substrate 10 forms thermal contact with the heat sink 210 to enhance the heat dissipation capacity of the LED lighting module 100, and can support the LED lighting module 100 to output higher power.

[0051] The driving circuit 40 and the LED light emitting assembly 30 are integrated into one module to form an integral LED lighting module 100, which can be used on bases 200 of different shapes and suitable for different types of lamps. For example, in this embodiment, it is used on the base 200 of a ceiling lamp to obtain a ceiling lamp. Of course, it can also be installed on other bases 200 such as wall lamps or floor lamps.

[0052] The heat sink 210 can be used to better dissipate the heat of the LED lighting module 100. Of course, in other embodiments, the structure of the heat sink 210 is also optional, that is, different types of structures can be selected, such as the circular heat sink 210 in this embodiment, and the square heat sink 210 in other embodiments; or no heat sink 210 is provided.

[0053] Furthermore, when a part such as a light source is damaged, the LED lighting module 100 can be removed separately and replaced with a new LED lighting module 100, and the base 200 and the heat sink can continue to be used without scrapping the entire lamp, thereby improving the sustainability of the product.

[0054] Furthermore, the outer edge of the top cover 20 is also integrally formed with a tongue piece 27 and an elastic buckle 28; the base 200 is provided with a slot 201 and a snap-on boss 202; the LED lighting module is rotated so that the tongue piece 27 on the top cover 20 is plugged into the slot 201 of the base 200, and the elastic buckle 28 on the top cover 20 is snap-on with the snap-on boss 202 of the base 200, thereby achieving a fixed and tight connection. The specific operation method is as follows: Figure 6 As shown, align the LED lighting module with the installation position (i.e., the tongue piece 27 is staggered with the slot 201, and the elastic buckle 28 is staggered with the clamping protrusion 202) and insert it into the base 200, then rotate the LED lighting module 100 forward, so that the tongue piece 27 is inserted into the slot 201 laterally, and the elastic buckle 28 is clamped into the clamping protrusion 202. When the elastic buckle 28 is completely clamped into the clamping protrusion 202, a "click" sound can be heard during the clamping; this confirms that the installation is in place. After the installation is completed, Figure 7When it is necessary to disassemble, first push the elastic buckle 28 away to release the clamping connection, and then rotate it in the opposite direction (or apply external force to the LED lighting module 100 to directly rotate it in the opposite direction to make the elastic buckle 28 disengage from the clamping boss 202), until the tongue 27 is laterally disengaged from the slot 201, and then disassembly can be achieved. In this way, by rotating the LED lighting module 100 in the forward and reverse directions, the LED lighting module 100 and the base 200 can be assembled and disassembled, and the connection structure is simple and easy to operate.

[0055] Embodiment 2

[0056] The LED lighting module 100 provided in this embodiment has a structure substantially the same as that of the first embodiment, except that: Figure 8 and Fig. 9 As shown, in this embodiment, the base plate 10 and the top cover 20 are fixedly connected by snapping. Specifically, a plurality of snap-fitting protrusions 14, specifically four snap-fitting protrusions 14, are provided on the periphery of the base plate 10, and four snap-fitting grooves 203 are provided on the top cover 20. During assembly, the four snap-fitting protrusions 14 of the base plate 10 are snapped into the four snap-fitting grooves 203 of the top cover 20 to achieve fixation.

[0057] In this embodiment, the base plate 10 is further provided with a plurality of threaded holes 15 , specifically three threaded holes 15 , and a magnetic screw 60 is threadedly connected in each threaded hole 15 .

[0058] This embodiment further provides an LED lamp, including a base 200 and an LED lighting module 100 . Specifically, the LED lighting module 100 is magnetically fixed to the base 200 via a magnetic screw 60 .

[0059] Furthermore, the present embodiment adopts a magnetic fixing method of the magnetic screw 60, which simplifies the fixed installation structure of the base 200 and the LED lighting module 100. At the same time, the height of the LED lighting module 100 relative to the base 200 can be adjusted by screwing in or out part or all of the magnetic screw 60; Figure 8 As shown, the magnetic screw 60 is completely screwed into the threaded hole 15. When the LED lighting module 100 needs to be raised, the three magnetic screws 60 are screwed out to a certain height, such as when adjusted to Fig. 9 The state shown, etc.; the magnetic screw 60 can be adjusted according to the actual required height; the applicability is better.

[0060] Specifically, in this embodiment, an assembly method of three magnetic screws 60 is adopted. Of course, in other embodiments, the number of magnetic screws 60 can also be one, two or more than three. When one magnetic screw 60 is used, a larger magnetic head structure can be selected to meet the firmness of magnetic attraction.
