Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a light source module, a ceiling lamp provided with the light source module, and a lighting system provided with the ceiling lamp. Background Art

[0002] LED is widely used in the field of lighting due to its advantages such as high efficiency and energy saving, long service life, strong controllability, small size, and good beam directionality. It is used in spotlights, downlights, track lights, ceiling lights, etc. Among them, when LED light source panels are used in ceiling lights, there are the following shortcomings:

[0003] First, the substrate of the LED light source board generally adopts a whole large substrate, which will increase the cost. In order to reduce the cost, the light sources are usually arranged in a centralized manner, but this will lead to a worse lighting effect.

[0004] Second, in order to solve the shortcomings of the first point mentioned above, the substrates of some existing LED light source panels are set as an integrated substrate in a ring or square shape. If the substrate is an irregular shape, the utilization rate of the substrate will be very low; and in order to ensure the lighting effect, a plurality of ring substrates with increasing size parameters are usually arranged in a zigzag nested arrangement or a plurality of square substrates with increasing size parameters are arranged in a zigzag nested arrangement. However, since the size parameters of each substrate are inconsistent and the number of substrates used in ceiling lamps with different lighting parameters is different, procurement is troublesome and error-prone.

[0005] In order to solve the above-mentioned shortcomings, the utility model patent with announcement number CN208794361U discloses an integrated substrate that can be nested and processed, which includes 13 elongated sections of substrates connected end to end, the width E of each section of the substrate is equal, and a hollow channel is left between each circle of the straight-edge spiral shape, and the width of the hollow channel is M. In the process of producing the integrated substrate that can be nested and processed, four integrated substrates that can be nested and processed that are rotated 0 degrees, 90 degrees, 180 degrees and 270 degrees around the center of symmetry can be nested, so that the integrated substrate that can be nested and processed can maximize the utilization rate of the panel combination area during the production process. However, the shortcomings of the integrated substrate that can be nested and processed are that the integrated substrate and the driving power supply are separately arranged, which increases the difficulty of installation and production costs. Summary of the invention

[0006] In order to solve the above problems, the main purpose of the utility model is to provide a light source module with good lighting effect, high substrate utilization, strong flexibility in use, strong practicality and low cost.

[0017] A further solution is that the number of light source panels is two to eight, and more than two light source panels are distributed in rotational symmetry.

[0018] It can be seen from the above that by designing the number of light source boards, the light source module can be adapted to ceiling lamps with different parameter requirements and different lighting effect requirements, thereby improving the flexibility and practicality of the use of the light source boards.

[0019] A further solution is that the substrate is an aluminum substrate, a ceramic substrate or a composite substrate; and the number of spiral turns of the extension portion is between 1 and 1.5 turns.

[0038] Ceiling lamp embodiment

[0039] Reference Figure 1 and Figure 2 The ceiling lamp 100 includes a light source module 1, a chassis 2 and a lampshade (not shown). The chassis 2 has a receiving position 21, and the light source module 1 is installed in the receiving position 21; the lampshade is installed on the chassis 2, and the lampshade covers the opening of the receiving position 21 to beautify the ceiling lamp 100 and prevent external dust and moisture from contacting and polluting the light source module 1, thereby protecting the light source module 1 and ensuring the lighting effect of the ceiling lamp 100.

[0040] Combination Figure 3 and Figure 4 , the light source module 1 includes at least one light source board 11; wherein the light source board 11 includes a substrate 111, a plurality of LED lamp beads 112 and a driving circuit 113. The substrate 111 has an integrally formed mounting portion 1111 and an extension portion 1112, and the extension portion 1112 extends from the mounting portion 1111 and extends around the mounting portion 1111 in a polygonal spiral or spiral shape. For example, in the present embodiment, the extension portion 1112 extends from the mounting portion 1111 and extends around the mounting portion 1111 in a polygonal spiral shape.

[0041] The LED lamp beads 112 are mounted on the extension portion 1112 of the substrate 111 , and the plurality of LED lamp beads 112 are distributed along the extension direction of the extension portion 1112 to improve the utilization rate of the substrate 111 and to make the plurality of LED lamp beads 112 as evenly distributed on the substrate 111 as possible.

[0042] The driving circuit 113 includes an electronic component assembly 1131 and a conductive circuit (not shown). The electronic component assembly 1131 is mounted on the mounting portion 1111, and the conductive circuit is arranged on the mounting portion 1111 and the extension portion 1112. The conductive circuit is electrically connected to the electronic component assembly 1131 and the LED lamp bead 112 respectively; wherein the conductive circuit is arranged on the substrate 111 during the manufacturing process of the substrate 111. Preferably, the substrate 111 is an aluminum substrate 111, so that the substrate 111 can reliably dissipate heat for the LED lamp bead 112 and the driving circuit 113, thereby ensuring the stability and reliability of the LED lamp bead 112 and the driving circuit 113, and delaying the light decay of the LED lamp bead 112, thereby ensuring the service life of the LED lamp bead 112 and the driving circuit 113; of course, as other optional solutions, the substrate 111 can also be a ceramic substrate 111 or a composite substrate 111 (MCPCB, metal-based printed circuit board).

[0043] In addition, a neutral contact 11111 and a live contact 11112 are also provided on the mounting portion 1111, and the neutral contact 11111 and the live contact 11112 are electrically connected to the conductive circuit respectively; wherein the neutral contact 11111 and the live contact 11112 are preferably also provided on the mounting portion 1111 of the substrate 111 during the manufacturing process of the substrate 111. The provision of the neutral contact 11111 and the live contact 11112 can make the connection position of the light source board 11 with the power supply cable more intuitive, and make the connection between the power supply cables and the light source board 11 more convenient.

[0044] Furthermore, the substrate 111 is provided with a plurality of through holes 1113, and the plurality of through holes 1113 are arranged on the mounting portion 1111 and the extension portion 1112; accordingly, the base 2 is preferably provided with a plurality of hot melt columns 22 at the bottom of the accommodating position 21, and the plurality of hot melt columns 22 correspond one-to-one to the plurality of through holes 1113, so that when the light source board 11 is installed on the base 2, a hot melt column 22 is inserted into a corresponding through hole 1113, and then the plurality of hot melt columns 22 are hot-melted by a hot-melt device to melt and deform them, so that the cooled hot melt columns 22 can fix the light source board 11 on the base 2, and the setting of the hot melt columns 22 can make the light source board 11 better fit on the base 2. Preferably, the base 2 is preferably made of a material with high thermal conductivity such as ABS (acrylonitrile-butadiene-styrene copolymer), PVC (polyvinyl chloride plastic), PP (polypropylene), PBT (polybutylene terephthalate) or PC (polycarbonate), so that the base 2 can assist in reliable heat dissipation of the light source board 11, thereby further ensuring the stability and reliability of the light source board 11, so as to better extend the service life of the LED lamp beads 112 and the driving circuit 113. Furthermore, the lampshade is made of PMMA (polymethyl methacrylate), so that the lampshade has good light transmittance, thereby ensuring the lighting effect of the ceiling lamp 100.

[0045] In addition, the light source board 11 preferably further includes a plurality of lenses 114, which are mounted on the extension portion 1112, and the plurality of lenses 114 correspond one-to-one to the plurality of LED lamp beads 112, so that when the lenses 114 are mounted on the extension portion 1112, one lens 114 covers a corresponding LED lamp bead 112. The provision of the lenses 114 can improve the lighting effect of the LED lamp bead 112, thereby improving the lighting effect of the light source module 1.

[0046] like Figure 1As shown, as an optional solution, the light source module 1 may include only one light source board 11. Of course, the number of light source boards 11 in the light source module 1 may also be more than two, and preferably, the number of light source boards 11 in the light source module 1 is between two and eight; when the number of light source boards 11 in the light source module 1 is more than two, the more than two light source boards 11 are rotationally symmetrically distributed. By designing the number of light source boards 11, the light source module 1 can be adapted to ceiling lamps 100 with different parameter requirements and different lighting effect requirements, thereby improving the flexibility and practicality of the use of the light source board 11. Among them, the number of spiral turns of the extension portion 1112 is preferably between 1 and 1.5 turns.

[0047] like Figure 5 As shown, the light source module 1 has two light source boards 11, and the two light source boards 11 are preferably distributed in 180° rotational symmetry, and the mounting portion 1111 of the light source board 11 is preferably rectangular, and the extension portion 1112 is preferably extended in a quadrilateral-like spiral shape, and the number of spiral turns of the extension portion 1112 is preferably about 1.25 turns.

[0048] Another example Figure 4 and Figure 6 As shown, the number of light source boards 11 of the light source module 1 is four, and the four light source boards 11 are preferably distributed in a rotational symmetry of 90°, and the mounting portion 1111 of the light source board 11 is preferably rectangular, and the extension portion 1112 is preferably extended in a quadrilateral spiral shape, and the number of spiral turns of the extension portion 1112 is preferably about 1.25 turns. Among them, when the mounting portion 1111 is rectangular, and the extension portion 1112 is in a quadrilateral spiral shape, the length of the mounting portion 1111 is L1, the width is L2, and the width of the extension portion 1112 is L3. In the length direction of the mounting portion 1111, the innermost circle spacing of the extension portion 1112 in a quadrilateral spiral shape is L4, L4 = L1 + L2 + 2 * L3 + W1, 3mm ≤ W1 ≤ 5mm.

[0049] For example Figure 7 As shown, the light source module 1 has three light source boards 11, which are preferably distributed in a rotationally symmetrical manner of 120°, and the mounting portion 1111 of the light source board 11 is preferably trapezoidal, and the extension portion 1112 is preferably extended in a hexagonal spiral shape, and the number of spiral turns of the extension portion 1112 is preferably approximately 1 turn.

[0050] Also like Figure 8 As shown, the number of light source boards 11 of the light source module 1 is six, and the six light source boards 11 are preferably distributed in a 60° rotational symmetry, and the mounting portion 1111 of the light source board 11 is preferably trapezoidal, and the extension portion 1112 is preferably extended in a hexagonal spiral shape, and the number of spiral turns of the extension portion 1112 is preferably about 1 turn.

[0051] By designing the number and structure of the light source panels 11, the light source module 1 can be adapted to ceiling lamps 100 of different shapes, different parameter requirements, and different lighting effect requirements, thereby ensuring the lighting effect of the ceiling lamp 100. Of course, in addition to the above, the number of light source panels 11 of the light source module 1 can also be two, four, or eight, and the extension portion 1112 extends in an octagonal spiral shape; etc. It should be noted that the number of light source panels 11 of the light source module 1 and the shape of the extension portion 1112 can also be other ways, so examples are given again one by one.

[0052] In summary, it can be seen that through the structural design of the light source board 11, more than two pieces can be spliced ​​together to form a large light source module 1, thereby improving the lighting effect, and the material used in the substrate 111 can be reduced to a certain extent while ensuring the same lighting effect, thereby reducing the cost; in addition, since each light source board 11 of the light source module 1 is a separate individual, the number of light source boards 11 and the relative position layout between the light source boards 11 can be increased or decreased according to the actual production requirements of the ceiling lamp 100 during use, thereby improving the flexibility and practicality of the use of the light source module 1; furthermore, when the LED lamp beads 112 or / and the driving circuit 113 on the light source board 11 are damaged and the light source board 11 needs to be scrapped, it is sufficient to scrap and replace the light source board 11 corresponding to the light source module 1, without scrapping the light source module 1 as a whole, thereby reducing the scrapping cost. In addition, a driving circuit 113 is arranged on the substrate 111, so that the substrate 111 can effectively dissipate the heat of the driving circuit 113, thereby eliminating the need to independently arrange the driving circuit 113, thereby reducing the production cost and improving the convenience of installation. The ceiling lamp 100 has good lighting effect, low production cost and high production flexibility by setting the light source module 1. When the LED lamp beads 112 and / or the driving circuit 113 on the light source board 11 are damaged and the light source board 11 needs to be scrapped, the scrapping cost is low.

[0053] Lighting system embodiment

[0054] The lighting system includes a control terminal and the ceiling lamp described in the above ceiling lamp embodiment. The control terminal is electrically connected to the driving circuit of the light source board of the ceiling lamp, and / or the control terminal and the driving circuit exchange information. Among them, the control terminal can be a conventional control panel (such as a mechanical switch panel), an intelligent control panel or a remote control. When the control terminal is a conventional control panel, the control terminal is electrically connected to the driving circuit. When the control terminal is an intelligent control panel or a remote control, the electronic component assembly of the driving circuit includes a first wireless communication module, and the control terminal is provided with a second wireless communication module; the control terminal is electrically connected to the driving circuit, and / or the first wireless communication module and the second wireless communication module exchange information. In addition, the control terminal can also be an intelligent mobile terminal (such as a mobile phone, a tablet computer, an intelligent wearing device, etc.), and can also be an artificial intelligence robot; the lighting system is provided with the above-mentioned ceiling lamp to achieve good lighting effect and low cost of use.

[0055] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
