[0028] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] See also Figure 1 In the related art, the flexible circuit board of the lamp is bonded to the fixing part by an adhesive. The size of the adhesive is generally designed to be a sheet according to the size of the flexible circuit board, and the excess part of the adhesive is cut according to the shape of the flexible circuit board. However, the utilization rate of the adhesive in this way is low. In actual production, only the part of the adhesive corresponding to the shape and size of the flexible circuit board is used, and the excess part of the adhesive will be cut and discarded, resulting in waste of adhesive materials and production waste.

[0031] Please also read Figure 2 and Figure 3 The embodiment of the present invention provides a lighting device 1000, which can be a bedside lamp, an indoor lamp, an atmosphere lamp, etc. The lighting device 1000 includes a lampshade 200 and a lamp panel assembly 100, and the lamp panel assembly 100 is assembled on the lampshade 200. In this way, the lampshade 200 can provide certain protection for the lamp panel assembly 100, which helps to reduce the situation where the lamp panel assembly 100 is exposed and damaged.

[0032] See also Figure 4 and Figure 5In some embodiments, the lighting device 1000 includes a fixing member 11, a plurality of adhesive members 12, a flexible circuit board 13, and a plurality of luminous bodies 14. The fixing member 11 may be a plastic member. The fixing member 11, the plurality of adhesive members 12, the flexible circuit board 13, and the plurality of luminous bodies 14 may be the structure of the light panel assembly 100.

[0033] In some embodiments, the fixing member 11 has a curved surface 1111, and the adhesive member 12 is in a strip shape, wherein adjacent adhesive members 12 are arranged at intervals, and the flexible circuit board 13 is bonded to the fixing member 11 through multiple adhesive members 12, and the flexible circuit board 13 completely covers the curved surface 1111, so that the flexible circuit board 13 can provide a larger area for bonding with the fixing member 11. Multiple light emitters 14 are assembled on the flexible circuit board 13, and the light-emitting surfaces 141 of the multiple light emitters 14 are located on the side of the flexible circuit board 13 away from the adhesive member 12.

[0034] In this way, a corresponding number of adhesives 12 can be flexibly selected to bond the fixing part 11 and the flexible circuit board 13 according to the size and area of ​​the fixing part 11 and the flexible circuit board 13, which helps to improve the adaptability of the adhesive 12 to the fixing parts 11 and the flexible circuit board 13 of different shapes, helps to increase the use area of ​​the adhesive 12 bonded to the fixing part 11 and the flexible circuit board 13, helps to improve the utilization rate of the adhesive 12, helps to reduce the waste of the adhesive 12, helps to save manufacturing costs, helps to ensure that the fixing part 11 and the flexible circuit board 13 are bonded in place, helps to ensure the stability of the flexible circuit board 13 attached to the fixing part 11, and also helps to facilitate the flexible circuit board 13 to be attached to the fixing part 11, and helps to reduce the wrinkling of the flexible circuit board 13.

[0035] In addition, the strip-shaped adhesive members 12 can also be in a regular shape, which facilitates the design and manufacture of the adhesive members 12 .

[0036] For example, when the size of the fixing member 11 and the flexible circuit board 13 is small, the bonding area of ​​the adhesive member 12 can be reduced by reducing the appropriate number of adhesive members 12; when the size of the fixing member 11 and the flexible circuit board 13 is large, the bonding area of ​​the adhesive member 12 can be increased by increasing the appropriate number of adhesive members 12.

[0037] This helps to improve the versatility of multiple adhesives 12, allowing users to change the use area of ​​adhesives 12 bonded to fixing parts 11 and flexible circuit boards 13 by adding or reducing single adhesives 12, thereby helping to increase the use area of ​​adhesives 12 and reduce waste of adhesives 12.

[0038] The adhesive 12 may have thermal conductivity to achieve heat dissipation for the flexible circuit board 13 .

[0039] Among them, the "multiple" in the above and below refers to two or more than two. For example, the adhesive members 12 can be two, three, four, five, six, seven, eight, nine, ten or other quantities, which can be set according to actual conditions.

[0040] In some embodiments, the fixing member 11 is in a hollow columnar shape, and a plurality of adhesive members 12 are arranged on the curved surface 1111 at intervals.

[0041] This helps reduce the number of adhesives 12 used, helps reduce manufacturing costs, and also helps reduce the situation where two adjacent adhesives 12 stick to each other, resulting in a reduction in the usable area of ​​the adhesives 12 , which helps improve the utilization rate of the adhesives 12 .

[0042] In addition, the flexible circuit board 13 can be surrounded by a plurality of adhesive members 12 to cover the curved surface 1111 , which helps to realize the lighting of the peripheral side of the lighting device 1000 and helps to improve the compactness of the structure of the lighting device 1000 .

[0043] The flexible circuit board 13 may be in a regular shape or an irregular shape, and may be specifically configured according to actual conditions. The following description will be made by taking the flexible circuit board 13 in an irregular shape as an example.

[0044] See also Figure 6 and Figure 7 In some embodiments, the flexible circuit board 13 may include a rectangular plate body 132 and a first bent plate body 133, wherein the rectangular plate body 132 is connected to the first bent plate body 133, wherein the first bent plate body 133 is bent in a direction away from the rectangular plate body 132. The fixing member 11 includes a shell body 112 and a first shell body 113, wherein the outer diameter of the first shell body 113 is smaller than the outer diameter of the shell body 112, the shell body 112 and the first shell body 113 both have a curved surface 1111, the rectangular plate body 132 covers the curved surface 1111 of the shell body 112, the first bent plate body 133 covers the curved surface 1111 of the first shell body 113, one side of the plurality of adhesive members 12 is attached to the curved surface 1111 of the shell body 112 and the curved surface 1111 of the first shell body 113, and the other side of the plurality of adhesive members 12 is attached to the rectangular plate body 132 and the first bent plate body 133.

[0045] In this way, the rectangular plate body 132 can be bonded to the curved surface 1111 of the shell body 112 through multiple adhesives 12, and the first bent plate body 133 can be bonded to the curved surface 1111 of the first shell 113 through multiple adhesives 12, so that the flexible circuit board 13 can be bonded to the fixing member 11 in sections, which helps to reduce the situation where the flexible circuit board 13 is too large and causes wrinkles when it is bonded to the fixing member 11, helps to ensure that the flexible circuit board 13 is more tightly bonded to the fixing member 11, and also helps to improve the stability of the flexible circuit board 13 bonded to the fixing member 11.

[0046] In some embodiments, the flexible circuit board 13 may also include a second bent plate body 134, the first bent plate body 133 is connected between the rectangular plate body 132 and the second bent plate body 134, the rectangular plate body 132, the first bent plate body 133 and the second bent plate body 134 are distributed along the height direction Y of the lighting device 1000, the first bent plate body 133 and the second bent plate body 134 are both bent in a direction away from the rectangular plate body 132 and the curvature radius of the first bent plate body 133 is greater than the curvature radius of the second bent plate body 134. The fixing member 11 includes a second shell 114, and the first shell 113 is connected to the shell body 112 and the second shell 114. The shell body 112, the first shell 113 and the second shell 114 are distributed along the height direction Y. The outer diameter of the first shell 113 is greater than the outer diameter of the second shell 114. The second shell 114 has a curved surface 1111. The second bent plate body 134 covers the curved surface 1111 of the second shell 114. One side of the multiple adhesive members 12 is also attached to the curved surface 1111 of the second shell 114, and the other side of the multiple adhesive members 12 is also attached to the second bent plate body 134.

[0047] In this way, the second bent plate body 134 can be correspondingly adhered to the curved surface 1111 of the second shell body 114 through multiple adhesives 12, and the flexible circuit board 13 can be respectively adhered to the fixing member 11 in sections through the rectangular plate body 132, the first bent plate body 133 and the second bent plate body 134, which helps to better reduce the situation where the flexible circuit board 13 is too large and causes wrinkles when it is adhered to the fixing member 11, helps to ensure that the flexible circuit board 13 is more closely adhered to the fixing member 11, and also helps to improve the stability of the flexible circuit board 13 adhered to the fixing member 11.

[0048] In some embodiments, the minimum spacing between any two adhesives 12 is equal. In this way, multiple adhesives 12 can be arranged relatively evenly between the flexible circuit board 13 and the fixing member 11, which helps to reduce the amount of adhesives 12 used, helps to reduce the manufacturing cost, helps to ensure that the bonding point of each adhesive 12 can withstand equal pressure, helps to disperse stress and thus enhance the bonding force between the flexible circuit board 13 and the fixing member 11, and helps to improve the stability of the flexible circuit board 13 attached to the fixing member 11.

[0049] In some embodiments, the fixing member 11 may be provided with a plurality of positioning portions 115 , the plurality of positioning portions 115 are distributed at intervals, the plurality of positioning portions 115 correspond one-to-one to the plurality of adhesive members 12 , and one side of the plurality of adhesive members 12 is respectively attached to the positioning portions 115 .

[0050] In this way, multiple positioning parts 115 can locate the bonding positions of multiple adhesives 12, which helps to improve the accuracy of the bonding positions of multiple adhesives 12 to the fixing part 11, helps to improve the efficiency of the bonding of multiple adhesives 12 to the fixing part 11, and thus helps to improve the efficiency of the flexible circuit board 13 to the fixing part 11.

[0051] See also Figure 7 In some embodiments, the positioning portion 115 may include a marking line 1152 , and one side of the plurality of adhesive members 12 is respectively attached to the marking line 1152 .

[0052] In this way, the marking line 1152 can be used as a marker to locate the bonding positions of multiple adhesives 12, so that multiple adhesives 12 can be bonded to the marking line 1152, which helps to improve the accuracy of the bonding positions of multiple adhesives 12 to the fixing member 11, helps to improve the efficiency of bonding multiple adhesives 12 to the fixing member 11, and thus helps to improve the efficiency of bonding the flexible circuit board 13 to the fixing member 11. The formation process of the marking line 1152 is simple and convenient to manufacture.

[0053] Among them, laser engraving or pad printing can be performed at the position where the fixing member 11 is pasted with the adhesive member 12, so that a marking line 1152 is formed on the surface of the fixing member 11, thereby facilitating the adhesive member 12 to be attached to the fixing member 11.

[0054] See also Figure 8 In some embodiments, the positioning portion 115 may include a marking pattern 1151 , and one side of the plurality of adhesive members 12 is respectively attached to the marking pattern 1151 .

[0055] In this way, the marking pattern 1151 can be used as a marker to locate the attachment positions of the multiple adhesives 12, and the multiple adhesives 12 can be attached to the marking pattern 1151, which helps to improve the accuracy of the attachment positions of the multiple adhesives 12 to the fixing member 11, helps to improve the efficiency of the attachment of the multiple adhesives 12 to the fixing member 11, and thus helps to improve the efficiency of the attachment of the flexible circuit board 13 to the fixing member 11. In addition, the formation process of the marking pattern 1151 is simple and convenient to manufacture.

[0056] The position where the fixing member 11 is pasted with the adhesive member 12 may be polished so that a brightly printed marking pattern 1151 is formed on the surface of the fixing member 11 , thereby facilitating the adhesive member 12 to be pasted on the fixing member 11 through the brightly printed marking pattern 1151 .

[0057] Please also read Figure 4 , Figure 7 and Fig. 9 In some embodiments, the fixing member 11 includes a first end 118 , the first end 118 is provided with a first limiting portion 116 , the flexible circuit board 13 is provided with a first matching portion 135 , and the first limiting portion 116 is engaged with the first matching portion 135 .

[0058] This helps to locate the fitting position of the flexible circuit board 13 and the fixing member 11, helps to improve the accuracy of positioning the flexible circuit board 13 to fit the fixing member 11, thereby helping to improve the efficiency of the flexible circuit board 13 to fit the fixing member 11, and also helps to reduce the displacement when positioning the flexible circuit board 13 to fit the fixing member 11, and helps to reduce the situation where the flexible circuit board 13 is crooked.

[0059] Exemplarily, the first limiting portion 116 may include a convex rib, which may be convexly provided on the first limiting portion 116, for example, the convex rib may be convexly provided on the surface of the first limiting portion 116 facing the flexible circuit board 13. The first matching portion 135 may include a card slot, which may be provided on the surface of the first matching portion 135 facing the fixing member 11, and the convex rib is opposite to the card slot and can be embedded in the card slot, so that the first limiting portion 116 and the first matching portion 135 can be engaged with each other.

[0060] For another example, the first limiting portion 116 may include a slot, which may be disposed on the first limiting portion 116, for example, the slot may be disposed on the surface of the first limiting portion 116 facing the flexible circuit board 13. The first matching portion 135 may include a convex rib, which may be convexly disposed on the surface facing the fixing member 11, and the convex rib is opposite to the slot and can be embedded in the slot, so that the first limiting portion 116 and the first matching portion 135 can be engaged with each other.

[0061] In some embodiments, the first limiting portion 116 avoids the positioning portion 115. In this way, the first limiting portion 116 will not hinder the adhesive 12 from being attached to the positioning portion 115, which helps to improve the efficiency of the adhesive 12 being attached to the positioning portion 115, and also helps to reduce the situation where the first limiting portion 116 is located at the positioning portion 115 and hinders the adhesive 12 from being attached, which helps to reduce the situation where the flexible circuit board 13 is loosened from the fixing member 11 due to the adhesive 12 not being attached properly.

[0062] Please also read Figure 4 , Figure 7 and Fig.10In some embodiments, the fixing member 11 also includes a second end 119, and the second end 119 and the first end 118 are respectively located at the two ends of the height direction Y of the lighting device 1000, and the second end 119 is provided with a second limiting portion 117, and the flexible circuit board 13 is provided with a second matching portion 136, and the second limiting portion 117 is engaged with the second matching portion 136.

[0063] In this way, the first limiting portion 116 and the second limiting portion 117 can perform doubly positioning on the flexible circuit board 13. The first limiting portion 116 and the second limiting portion 117 can position the flexible circuit board 13 from both sides of the fixing member 11, which helps to better position the fitting positions of the two sides of the flexible circuit board 13 with the fixing member 11, helps to better improve the accuracy of positioning the flexible circuit board 13 to fit the fixing member 11, thereby helping to improve the efficiency of the flexible circuit board 13 fitting to the fixing member 11, and also helps to better reduce the displacement when positioning the flexible circuit board 13 to fit the fixing member 11, and helps to reduce the situation where the flexible circuit board 13 is crooked.

[0064] In addition, the flexible circuit board 13 can be mounted on the fixing member 11 by limiting it through the first matching portion 135 and the second matching portion 136. The flexible circuit board 13 can be attached to the fixing member 11 without the need for a fixture, which helps to simplify the steps of attaching the flexible circuit board 13 to the fixing member 11 and helps to improve the efficiency of attaching the flexible circuit board 13 to the fixing member 11.

[0065] Exemplarily, when the flexible circuit board 13 needs to be attached to the fixing member 11, multiple adhesive members 12 can be attached to the positioning portion 115, and then the first limiting portion 116 is engaged with the first matching portion 135, and the second limiting portion 117 is engaged with the second matching portion 136, so that the flexible circuit board 13 can be initially fixed to the fixing member 11, and then the flexible circuit board 13 can be pressed and attached to achieve the mounting of the flexible circuit board 13 and the fixing member 11.

[0066] In some embodiments, the second limiting portion 117 avoids the positioning portion 115. In this way, the second limiting portion 117 will not hinder the adhesive 12 from being attached to the positioning portion 115, which helps to improve the efficiency of the adhesive 12 being attached to the positioning portion 115, and also helps to reduce the situation where the second limiting portion 117 is located at the positioning portion 115 and hinders the adhesive 12 from being attached, which helps to reduce the situation where the flexible circuit board 13 is loosened from the fixing member 11 due to the adhesive 12 not being attached properly.

[0067] Re-read Figure 6 and Figure 7In some embodiments, the first limiting portion 116 and the second limiting portion 117 are distributed along the height direction Y of the lighting device 1000, and the centers of the first limiting portion 116 and the second limiting portion 117 are aligned, that is, the center of the first limiting portion 116 and the center of the second limiting portion 117 are located on the same straight line in the height direction Y. In this way, the first matching portion 135 and the second matching portion 136 can be located on the same straight line to achieve alignment, which facilitates the flexible circuit board 13 to be attached to the fixing member 11 from both sides of the first matching portion 135 and the second matching portion 136, helps to reduce the difficulty of attaching the flexible circuit board 13 to the fixing member 11, helps to facilitate the attachment of the flexible circuit board 13 to the fixing member 11, helps to improve the efficiency of attaching the flexible circuit board 13 to the fixing member 11, and also helps to reduce the wrinkling of the flexible circuit board 13.

[0068] Exemplarily, when the flexible circuit board 13 needs to be attached to the fixing member 11, multiple adhesive members 12 can be attached to the positioning portion 115, and then the first limiting portion 116 is engaged with the first matching portion 135, and the second limiting portion 117 is engaged with the second matching portion 136, so that the flexible circuit board 13 can be initially fixed to the fixing member 11, and then the flexible circuit board 13 is pressed and attached from both sides of the first matching portion 135 and the second matching portion 136, thereby realizing the mounting of the flexible circuit board 13 and the fixing member 11.

[0069] In summary, in the lighting device 1000 provided in the embodiment of the present invention, the adhesive member 12 of the lighting device 1000 is in a strip shape, the flexible circuit board 13 is bonded to the fixing member 11 through a plurality of adhesive members 12, and the flexible circuit board 13 completely covers the curved surface 1111. A plurality of light emitters 14 are mounted on the flexible circuit board 13, and the light emitting surfaces 141 of the plurality of light emitters 14 are located on the side of the flexible circuit board 13 away from the adhesive member 12. In this way, the corresponding number of adhesives 12 can be flexibly selected to bond the fixing part 11 and the flexible circuit board 13 according to the size and area of ​​the fixing part 11 and the flexible circuit board 13, which helps to improve the adaptability of the adhesive 12 to the fixing parts 11 and the flexible circuit board 13 of different shapes, helps to increase the use area of ​​the adhesive 12 bonded to the fixing part 11 and the flexible circuit board 13, helps to improve the utilization rate of the adhesive 12, helps to reduce the waste of the adhesive 12, helps to save the manufacturing cost, helps to ensure that the fixing part 11 and the flexible circuit board 13 are bonded in place, helps to ensure the stability of the flexible circuit board 13 attached to the fixing part 11, and also helps to facilitate the attachment of the flexible circuit board 13 to the fixing part, and helps to reduce the wrinkling of the flexible circuit board 13.
