[0020] In one embodiment, as Figure 1 and Figure 2 shown, an LED lamp board module 10 includes: a circuit board 100, a plurality of LED lamp beads 200, wires 300, and a circuit component 400; the circuit board 100 is in a long strip shape, the circuit board 100 is divided into a light-emitting part 110 and a control part 120, the light-emitting part 110 of the circuit board 100 is arranged in a coiled manner, and the control part 120 is connected to one side of the light-emitting part 110; each of the LED lamp beads 200 is evenly spaced on the light-emitting part 110 of the circuit board 100; the circuit component 400 is arranged on the control part 120 of the circuit board 100, the circuit component 400 is electrically connected to the LED lamp beads 200, the wire 300 is connected to the circuit component 400, and the wire 300 is used for electrically connecting to an external power supply.
[0021] Specifically, by arranging the LED lamp beads 200 and the circuit components 400 on the same circuit board 100, that is, both the power supply and the light source are arranged on the same circuit board 100. By arranging the circuit components and the optical components on the same circuit board 100, the connection of the wire 300 between the circuit component 400 and the optical component is eliminated. The connection reliability is strong, the soldering process of the wire 300 between the power supply board and the light source board during the finished product assembly is reduced, and all the processing processes can be completed only by one-time chip mounting and furnace passing, which greatly improves the process efficiency of the optoelectronic module and the finished product assembly process. At the same time, the light-emitting part 110 of the circuit board 100 is arranged in a coiled manner, which is convenient for assembling each LED lamp board module 10 into a complete lamp board. Through the above-mentioned LED lamp board module 10, various defects existing in the optoelectronic solution with independent power supply and light source are solved. At the same time, the material cost is reduced, the production process is simplified, the reliability of the product is improved, and the finished product assembly of the lamp is simplified.
[0022] In one embodiment, the circuit component 400 includes: a power supply part, a driving circuit, and a control circuit. The input end of the power supply part is electrically connected to the wire 300, and the driving circuit and the control circuit are respectively electrically connected to the output end of the power supply part. The power supply part is used to provide a stable power supply voltage or current. The driving circuit is used to convert the power supply voltage or current into a voltage or current suitable for the normal operation of the LED lamp beads 200. The LED lamp beads 200 generally require a driving current of about 20 mA. Therefore, the driving circuit can be implemented by devices such as resistors, current sources, and current control chips. The control circuit is used to adjust parameters such as the brightness or color temperature of the LED lamp beads 200. The brightness of the LED lamp beads 200 can be controlled by adjusting the magnitude of the current or voltage through PWM, and more complex dimming effects can also be achieved through a single-chip microcomputer or a control chip.
[0023] In order to prevent the circuit component 400 on the circuit board 100 from generating heat and affecting the LED lamp beads 200, in one embodiment, as Figure 1 and Figure 2 shown, a thermal barrier baffle 500 is arranged between the light-emitting part 110 and the control part 120 of the circuit board 100. The thermal barrier baffle 500 is used to block the heat transfer between the light-emitting part 110 and the control part 120. Specifically, the thermal resistance partition is vertically established on the circuit board 100, and the thermal barrier baffle 500 can effectively block the heat dissipated by the circuit component 400, thereby reducing the influence of heat on the light emission of the LED lamp beads 200.
[0024] In order to fixedly install the circuit board 100, in one embodiment, as Figure 1 and Figure 2As shown, a plurality of mounting holes 130 are formed in the circuit board 100, and the mounting holes 130 are through holes. Specifically, the mounting holes 130 are arranged at intervals on the light-emitting part 110 of the circuit board 100. And each of the mounting holes 130 is a through hole, which is convenient for bolts to pass through and fixedly mount the LED lamp board module 10.
[0025] To meet the installation requirements of various different methods, in one embodiment, as Figure 1 and Figure 2 shown, the mounting hole 130 is an oval hole. Specifically, by setting the mounting hole 130 as an oval hole, various installation and fixing requirements such as screw locking, hot riveting, and snap fastening can be met.
[0026] To make the light-emitting effect of the LED lamp beads 200 better, in one embodiment, as Figure 1 shown, optical lenses 600 are respectively arranged on each of the LED lamp beads 200. Specifically, each of the LED lamp beads 200 is covered with the optical lens 600. When the light emitted by the LED lamp beads 200 passes through the optical lens 600 and is emitted, the optical lens 600 can disperse the light emitted by the LED lamp beads 200, so that the light looks softer, that is, the light-emitting effect of the LED lamp beads 200 is better.
[0027] To facilitate the alignment and assembly of multiple LED lamp board modules 10, in one embodiment, as Figure 1 , Figure 2 and Figure 3 shown, chamfers are provided at both the outer corners and the inner corners of the light-emitting part 110 of the circuit board 100. Specifically, the chamfers at the outer corners of the light-emitting part 110 of the circuit board 100 are arranged to match the chamfers at the inner corners, that is, the chamfer angles at the outer corners are the same as the angles at the inner corners. Through the above settings, when assembling multiple LED lamp board modules 10, the outer corner of the circuit board 100 of one LED lamp board module 10 can be matched and aligned with the inner corner of the circuit board 100 of another LED lamp board module 10, thus facilitating the assembly of multiple LED lamp board modules 10.
[0028] In one embodiment, as Figure 1 , Figure 2 and Figure 3 shown, the corners of the control part 120 of the circuit board 100 are provided with rounded corners. Specifically, when four LED lamp board modules 10 are assembled into a four-in-one assembled lamp board 20, the corners of the control part 120 are the outer corners of the four-in-one assembled lamp board 20. Therefore, by setting them as rounded corners, it can avoid hurting people due to overly sharp corners.
[0029] In one embodiment, as Figure 3 shown, a four-in-one panel-type light board 20 includes the LED light board module 10 described in any of the above embodiments, and there are four of the LED light board modules 10. The four LED light board modules 10 are assembled into a rectangular-shaped four-in-one panel-type light board 20. Specifically, the four LED light board modules 10 are arranged in a similar mosquito coil shape to form a four-in-one panel-type light board 20. Through the above-mentioned panel layout combination design similar to the mosquito coil shape, the material of the circuit board 100 can be saved, and the utilization efficiency of the board material of the circuit board 100 can reach 95%. A four-in-one panel-type light board 20 is assembled by four complete LED light board modules 10, and the four LED light board modules 10 are independent of each other and do not affect each other. When the LED beads 200 in one LED light board module 10 have problems, it does not affect the LED beads 200 of other LED light board modules 10 from emitting light. The four-in-one design of the four-in-one panel-type light board 20 has strong integrity, and the whole board can be pasted and passed through the furnace, greatly improving the pasting efficiency and reducing the pasting cost.
[0030] Compared with the prior art, the present utility model has at least the following advantages: By arranging the circuit components and the optical components on the same circuit board, the LED light board module eliminates the wire connection between the circuit component and the optical component, has strong connection reliability, reduces the wire soldering process between the power board and the light source board during the finished product assembly, and only needs to pass through the furnace for one-time pasting to complete all the processing processes, greatly improving the process efficiency of the optoelectronic module and the finished product assembly process. At the same time, the light-emitting part of the circuit board is arranged in a coiled manner, which is convenient for assembling each LED light board module into a complete light board. Through the above-mentioned LED light board module, various defects existing in the optoelectronic solution with independent power supply and light source are solved. At the same time, the material cost is reduced, the production process is simplified, the reliability of the product is improved, and the finished product assembly of the lamp is simplified.
[0031] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limiting the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
