For example, vertical usually means that the included angle with the reference line is 90 degrees, but in the present application, vertical means including the case within 80 degrees to 100 degrees.

[0023] As shown in Figures 1 to 6 , the present application provides an LED lamp 100 in an embodiment, the LED lamp 100 comprises a base 1, a photoelectric module 2 and a lampshade 3, the photoelectric module 2 is arranged on the base 1, and the lampshade 3 is connected and fixed with the base 1 and covers the light exit side of the photoelectric module 2.

[0024] Specifically, as shown in Figure 3 , Figure 4 , the base 1 can be circular, square or the like, and in the present embodiment, the base 1 is circular or substantially circular. The base 1 comprises a first face 101 and a second face 102, the first face 101 is arranged towards the light exit face of the LED lamp, and the second face 102 is arranged away from the light exit face of the LED lamp. When the LED lamp 100 is installed to an installation face (such as a ceiling, not shown), the second face 102 of the base 1 is arranged towards the installation face, and the installation face is for example a ceiling.

[0025] The base 1 comprises a first bottom wall 111, a second bottom wall 112 and a third bottom wall 113 arranged in sequence from outside to inside, and a first side wall 12, a second side wall 13 and a third side wall 14 arranged in sequence from outside to inside. The first bottom wall 111, the second bottom wall 112 and the third bottom wall 113 are arranged in parallel with the lampshade 3. The first side wall 12 and the second side wall 13 are arranged in perpendicular with the first bottom wall 111, and the third side wall 14 is arranged in perpendicular with the third bottom wall 113. The first bottom wall 111 is connected with the first side wall 12 and the second side wall 13 to form a first groove 15, the second bottom wall 112 is connected with the second side wall 13 and the third side wall 14 to form a second groove 16, and the third side wall 14 surrounds the third bottom wall 113 to form a third groove 17. The opening of the first groove 15 and the opening of the third groove 17 are towards the first face 101, and the opening of the second groove 16 is towards the second face 102.

[0026] As shown in Figure 4 , the base 1 comprises a bottom wall 11 and a first side wall 12 arranged around the bottom wall 11, and the first side wall 12 is arranged on the first face 101. The bottom wall 11 is arranged in parallel or substantially parallel with the mounting face, the first side wall 12 is arranged in perpendicular or substantially perpendicular with the bottom wall 11, and the first side wall 12 is arranged in perpendicular or substantially perpendicular with the mounting face. On the LED lamp, the bottom wall 11 is arranged away from the side of the lampshade 3, and the bottom wall 11 is arranged in parallel or substantially parallel with the lampshade 3. By arranging the first side wall 12, the base 1 has a certain height, so that the mounting structure (such as the hanger 5) and / or the power supply structure (such as the power supply module 22) can be arranged in the base 1. The lampshade 3 can be connected with the first side wall 12, so that the lampshade 3 is connected and fixed with the base 1. The side of the first side wall 12 away from the mounting face is provided with a reinforcing rib 121, that is, the side of the first side wall 12 close to the light emitting side of the LED lamp is provided with the reinforcing rib 121. The reinforcing rib 121 is, for example, a ring-shaped member formed on the side edge of the first side wall 12 and having a thickness greater than that of the first side wall 12. The reinforcing rib 121 can enhance the structural strength of the first side wall 12, and thus enhance the structural strength of the base 1, prevent the base 1 from deforming during use, and the surface of the reinforcing rib 121 is relatively smooth and round, preventing personnel from scratching during assembly of the LED lamp 100.

[0027] In a specific embodiment, as Figure 4As shown, the bottom wall 11 can be provided with a second groove 16, and a power supply structure (a power supply module 22) can be arranged in the second groove 16. The second groove 16 can be a circular ring groove or other shapes. The recess of the second groove 16 can be arranged towards the mounting surface or away from the mounting surface. In this embodiment, the second groove 16 is a circular ring groove, and the opening of the second groove 16 is arranged towards the mounting surface. In other words, the opening of the second groove 16 is arranged away from the light emitting side. By arranging the second groove 16, the bottom wall 11 is formed with a first bottom wall 111, a second bottom wall 112 and a third bottom wall 113 arranged from outside to inside, i.e. the bottom wall 11 includes the first bottom wall 111, the second bottom wall 112 and the third bottom wall 113 arranged from outside to inside. In other words, the first bottom wall 111 is arranged at the outermost side, the third bottom wall 113 is arranged at the innermost side, and the second bottom wall 112 is arranged between the first bottom wall 111 and the third bottom wall 113.

[0028] As shown in Figure 3 , Figure 4 , the second groove 16 further includes a second side wall 13 and a third side wall 14, the first bottom wall 111 and the second bottom wall 112 are connected by the second side wall 13, the second side wall 13, the first bottom wall 111 and the first side wall 12 together form the first groove 15, i.e. the second bottom wall 112 is the bottom of the first groove 15. By arranging the first groove 15, the heat dissipation area of the power supply module 22 can be increased, thereby improving the heat dissipation effect of the LED lamp. The second bottom wall 112 and the third bottom wall 113 are connected by the third side wall 14, the third bottom wall 113 forms a third groove 17 at the position close to the third side wall 14, and the openings of the first groove 15 and the third groove 17 are arranged away from the mounting surface, and the third groove 17 is used to arrange a mounting structure (such as a hanger 5).

[0029] As shown in Figures 3 to 5 , the LED lamp 100 can include a hanger 5 for mounting the LED lamp 100 to the mounting surface. The hanger 5 is arranged in the third groove 17. The LED lamp 100 further includes a hanger bracket 51, and the hanger 5 is connected and fixed with the hanger bracket 51. The hanger 5 can be connected with the third bottom wall 113 through the hanger bracket 51, i.e. the hanger 5 is connected with the hanger bracket 51, the hanger bracket 51 is connected with the third bottom wall 113, and the hanger bracket 51 and the third bottom wall 113 can be fixed by one or more of the following methods, such as gluing, welding, clamping, nesting, screw locking, magnetic attraction, etc. The third bottom wall 113 is provided with a first through hole 1131, and the hanger 5 is at least partially exposed or protruded from the first through hole 1131, so as to facilitate the connection of the hanger 5 with the mounting surface.

[0030] In this embodiment, as shown in Figure 4As shown, the first groove 15 and the second groove 16 are both circular ring grooves, and the third groove 17 is a cylindrical groove. The arrangement of the first groove 15, the second groove 16 and the third groove 17 not only enhances the structural strength of the base 1, but also allows other components to be installed, fully utilizes the space of the base 1, makes the structure of the LED lamp 100 more compact, and further reduces the volume of the LED lamp 100, especially the thickness of the whole LED lamp 100.

[0031] As shown in Figure 3 , As shown in Figure 5 , the photoelectric module 2 can include a light source module 21 and a power supply module 22. The power supply module 22 is electrically connected to the light source module 21, and the power supply module 22 supplies power to the light source module 21, and the light source module 21 is used for light emission. The light source module 21 and the power supply module 22 can be arranged on both sides of the base 1, i.e. the light source module 21 is arranged on the side of the base 1 away from the mounting surface, and the power supply module 22 is arranged on the side of the base 1 facing the mounting surface, i.e. the light source module 21 is arranged on the first surface 101 of the base 1, and the power supply module 22 is arranged on the second surface 102 of the base 1. Thus, the heat generated by the light source module 21 and the power supply module 22 during operation can be dissipated in two different directions through the base 1, thereby reducing the problem of mutual heat dissipation between the light source module 21 and the power supply module 22. The light source module 21 and the power supply module 22 can also be arranged on the same side of the base 1, i.e. the light source module 21 and the power supply module 22 are both arranged on the side of the base 1 away from the mounting surface, or in other words, the light source module 21 and the power supply module 22 are both arranged on the first surface 101 of the base 1, so that the light source module 21 and the power supply module 22 are on the same side and include a height overlap. By overlapping the height, the height of the light-emitting side can be effectively utilized, thereby reducing the height of the mounting side, and further reducing the height of the LED lamp, making the LED lamp appearance light, thin and beautiful. The power supply module 22 is covered with a protective cover 221, in other words, the protective cover 221 covers the power supply module 22. The protective cover 221 can prevent foreign matter from contaminating the power supply module 22, and can also prevent foreign matter from causing short circuit between elements on the power supply module 22, ensuring that the power supply module 22 can operate safely and stably. The protective cover 221 can be connected to the bottom wall 11, and the protective cover 221 and the bottom wall 11 can be fixed by one or more of the following methods: adhesive, welding, clamping, nesting, screw locking, magnetic attraction, etc.

[0032] In this embodiment, as Figure 5As shown, the light source module 21 and the power supply module 22 can be respectively arranged at two sides of the base 1, that is, the light source module 21 and the power supply module 22 can be respectively arranged at two sides of the bottom wall 11, that is, the light source module 21 is arranged at a side of the bottom wall 11 away from the mounting surface, that is, the light source module 21 is arranged on the first surface 101 of the base 1, and the light source module 21 and the bottom wall 11 can be fixed by one or more of the following manners, such as gluing, welding, clamping, nesting, screw locking, magnetic attraction, etc. The power supply module 22 is arranged at a side of the bottom wall 11 toward the mounting surface, that is, the power supply module 22 is arranged on the second surface 102 of the base 1, and the power supply module 22 and the bottom wall 11 can be fixed by one or more of the following manners, such as gluing, welding, clamping, nesting, screw locking, magnetic attraction, etc.

[0033] As shown in Figure 3 , Figure 5 , the lampshade 3 is arranged at the light emitting side of the light source module 21, and the light emitted by the light source module 21 passes through the lampshade 3 and is emitted. The shape of the lampshade 3 matches the base 1, and in this embodiment, the lampshade 3 is substantially circular. The lampshade 3 is connected with the base 1, and the lampshade 3 and the base 1 can be fixed by one or more of the following manners, such as gluing, welding, clamping, nesting, screw locking, magnetic attraction, etc. In other words, the light source module 21 is arranged between the base 1 and the lampshade 3. The lampshade 3 and the base 1 can form a closed space, which can prevent dust, flying insects and other foreign matters from entering, thereby avoiding the influence of foreign matters on the light emitting effect of the light source module 21, and also protecting the light source module 21 from damage caused by external force. The light source module 21 is accommodated in the closed space formed by the lampshade 3 and the base 1.

[0034] As shown in Figure 3 , Figure 5 , the light source module 21 can further include a light source assembly 211 and an optical assembly 212, the optical assembly 212 is arranged at the light emitting side of the light source assembly 211, and the lampshade 3 is arranged outside the optical assembly 212, that is, the optical assembly 212 is arranged between the lampshade 3 and the light source assembly 211, and the light emitted by the light source assembly 211 passes through the optical assembly 212 and then passes through the lampshade 3 and is emitted. Thus, the light emitted by the light source assembly 211 can be adjusted by the optical assembly 212. The optical assembly 212 can be a lens structure, and the light emitted by the light source assembly 211 can increase the light emitting angle after being adjusted by the optical assembly 212.

[0035] As shown in Figure 3 , Figure 6As shown, the light source assembly 211 and the power module 22 are electrically connected. The light source assembly 211 can include a light source plate 2111 and lamp beads 2112, which can be LED lamp beads 2112. The number of the lamp beads 2112 is preferably multiple, and the multiple lamp beads 2112 are arranged on the light source plate 2111. The light source plate 2111 can be in a circular ring shape, and the light source plate 2111 is arranged corresponding to the second bottom wall 112, i.e. the light source plate 2111 is arranged on the second bottom wall 112. The light source plate 2111 and the second bottom wall 112 can be fixed by one or more of the following methods, such as gluing, welding, clamping, nesting, screw locking, magnetic attraction, etc. The multiple lamp beads 2112 can be arranged on the light source plate 2111 according to a certain rule to improve the uniformity of the light emitted by the lamp beads 2112, and thus improve the uniformity of the light emitted by the LED lamp 100. In this embodiment, part of the lamp beads 2112 can be close to the outer edge of the light source plate 2111 and uniformly distributed along the circumference of the light source plate 2111, and part of the lamp beads 2112 can be close to the inner edge of the light source plate 2111 and uniformly distributed along the circumference of the light source plate 2111. Thus, the light source assembly 211 can simultaneously light up the outer side and the center part of the LED lamp 100 when emitting light, and thus the light emitted by the LED lamp 100 is uniform without obvious dark and bright areas.

[0036] As shown in Figure 3 , Figure 6 The optical assembly 212 can include one or more lenses 2121, so as to adjust the light emitting angle of the light emitted by the light source assembly 211. One lens 2121 can be arranged corresponding to one lamp bead 2112, i.e. one lens 2121 covers one lamp bead 2112, so as to adjust the light emitting of different lamp beads 2112. Multiple lamp beads 2112 can be arranged corresponding to one lens 2121, i.e. one lens 2121 can cover multiple lamp beads 2112, so as to adjust the light emitting of the multiple lamp beads 2112 as a whole.

[0037] The lens 2121 can refract or reflect the light emitted by the lamp bead 2112, or both, so as to achieve diffusion and scattering of the light. When the light of the LED lamp 100 passes through the lens 2121, it will be dispersed into light in multiple directions, thereby achieving a more uniform lighting effect. At the same time, the material and design of the lens 2121 can also affect the performance of the color temperature, color reproduction, etc. of the light, so multiple factors need to be considered when selecting and designing the LED lamp 100. The lens 2121 can convert the direct light emitted by the lamp bead 2112 into scattered light, achieving a more uniform lighting effect. In this embodiment, the lens 2121 adopts a large-angle lens 2121, that is, the lens 2121 can scatter the light emitted by the lamp bead 2112 in all directions to form a conical light pattern, so that the light-emitting angle of the lamp bead 2112 can exceed 170°, and the larger the light-emitting angle of the lamp bead 2112, the better the light-emitting uniformity of the LED lamp 100. That is, the lens 2121 can disperse the light emitted by the lamp bead 2112, which can avoid bright spots on the LED lamp 100, and at the same time can cause part of the light to deviate towards the center of the LED lamp 100, thereby avoiding dark spots in the center of the LED lamp 100, and also can cause part of the light to be incident on the mounting surface, avoiding dark spots on the mounting surface.

[0038] As shown in Figure 3 , Figure 6 , the optical assembly 212 can also include a lens holder 2122, the shape of the lens holder 2122 being the same as or similar to that of the light source plate 2111, and the lens 2121 is arranged on the lens holder 2122 and corresponds to the lamp bead 2112, so that the lens 2121 can be arranged on the lamp bead 2112. The lens holder 2122 can provide support for the lens 2121 to prevent the lens 2121 from shifting position, facilitate installation of the optical assembly 212, and improve the assembly efficiency of the LED lamp 100. The material of the lens holder 2122 is preferably the same as that of the lens 2121, so that the lens holder 2122 can also refract or reflect the light emitted by the lamp bead 2112, further improving the light-emitting uniformity of the LED lamp 100.

[0039] As shown in Figures 1 to 3 , Figure 6As shown, the lampshade 3 can include a light exit portion 31 and an edge portion 32, the light exit portion 31 is clamped in the clamping groove of the edge portion 32, and the edge portion 32 is fixedly connected with the base 1, so that the lampshade 3 is fixedly connected with the base 1. In other words, the lampshade 3 includes the light exit portion 31 and the edge portion 32, the light exit portion 31 is fixedly connected with one end of the edge portion 32, and the other end of the edge portion 32 is fixedly connected with the base 1. The light exit portion 31 is arranged on the light emitting side of the light source module 21, and further, the light exit portion 31 is arranged directly in front of the light emitting direction of the light source module 21, and the light emitted by the light source module 21 is emitted through the light exit portion 31. The light exit portion 31 is of transparent or translucent material, and in this embodiment, the light exit portion 31 is preferably of translucent material. The light exit portion 31 of translucent material can adjust the light emitting angle of the light source module 21, make the light emitted by the LED lamp 100 more uniform, and also make the light emitted by the light source module 21 more soft, thereby improving the visual experience of the user.

[0040] As shown in Figure 5 , the light exit portion 31 can be a plane, compared with the arc-shaped light exit portion 31, the plane-shaped light exit portion 31 can reduce the height of the lampshade 3, and further reduce the overall height of the LED lamp 100.

[0041] As shown in Figures 1 to 3 , Figure 6 , the edge portion 32 of the lampshade 3 can include a frame portion 321 and a support ring 322, and the frame portion 321 is connected with the support ring 322. The frame portion 321 and the support ring 322 can be connected and fixed by one or more of the following connection methods: gluing, welding, clamping, nesting, screw locking, magnetic attraction, etc. Compared with the support ring 322, the frame portion 321 is arranged away from the mounting surface. In other words, the distance from the frame portion 321 to the mounting surface is greater than the distance from the support ring 322 to the mounting surface. That is, one end of the support ring 322 is connected with the frame portion 321, and the other end of the support ring 322 is connected with the base 1. In this embodiment, one end of the frame portion 321 close to the light source module 21 is provided with a clamping portion 3212, and the support ring 322 is provided with a second clamping groove 3221, and the frame portion 321 and the support ring 322 are connected and fixed by the clamping portion 3212 and the second clamping groove 3221.

[0042] The light exit portion 31 and the frame portion 321 can be fixed by one or more of the following methods: gluing, welding, clamping, nesting, screw locking, magnetic attraction, etc. In this embodiment, one end of the frame portion 321 away from the light source module 21 is provided with a first clamping groove 3211, and the outer edge of the light exit portion 31 is clamped in the first clamping groove 3211 of the frame portion 321, so as to realize the mutual connection of the light exit portion 31 and the frame portion 321.

[0043] The frame part 321 is preferably made of aluminum material. The aluminum material of the frame part 321 has high structural strength, and provides stable support for the LED lamp 100. Meanwhile, the aluminum material of the frame part 321 has a certain reflection effect on the light emitted by the lamp beads 2112, thereby improving the uniformity of the light emitted by the LED lamp 100. In addition, the aluminum material has low density, which can reduce the overall weight of the LED lamp 100. Moreover, the aluminum material has low price, which can reduce the production cost of the LED lamp. In addition, the aluminum material has good heat conductivity, which can dissipate the heat generated by the LED lamp 100 to the air, thereby improving the stability of the LED lamp 100.

[0044] The support ring 322 is connected with the base 1, so that the lampshade 3 is connected and fixed with the base 1. The support ring 322 and the base 1 can be fixed by one or more of the following methods, such as gluing, welding, clamping, nesting, screw locking, magnetic attraction, etc. In the embodiment, as shown in Figure 6 the end of the support ring 322 close to the base 1 is provided with a buckle structure 3222, and the base 1 is provided with a boss 131. The support ring 322 and the base 1 are detachably connected through the buckle structure 3222 and the boss 131, so as to facilitate the disassembly of the support ring 322 and the base 1. Specifically, the boss 131 is arranged on the second side wall 13 and extends towards the first side wall 12, and the buckle structure 3222 is arranged on the inner side of the support ring 322. When the support ring 322 is connected with the base 1, part of the support ring 322 is inserted into the first groove 15. By relatively rotating the support ring 322 and the base 1, the buckle structure 3222 and the boss 131 can be combined or separated, so as to realize the detachable connection between the support ring 322 and the base 1. The number of the buckle structure 3222 and the boss 131 corresponds to the arrangement, and the number of the buckle structure 3222 and the boss 131 is preferably multiple and uniformly distributed, so as to improve the stability of the connection between the support ring 322 and the base 1.

[0045] The support ring 322 can be made of a light-transmitting material. That is, the support ring 322 is made of a light-transmitting material. Part of the light emitted by the light source module 21 can be emitted from the support ring 322 and irradiate to the mounting surface, so as to prevent dark spots from appearing on the mounting surface. The support ring 322 is preferably made of a translucent material, so that the light irradiated to the mounting surface is more uniform and soft, thereby avoiding bright spots on the mounting surface, and improving the light emission effect of the LED lamp 100 and the visual experience of the user.

[0046] As shown in Figure 5 , Figure 6As shown, the support ring 322 may have an extension 3223 at one end near the base 1. The extension 3223 is parallel to the bottom wall 11 of the base 1 and contacts the bottom wall 11 of the base 1 to enhance the stability of the connection between the support ring 322 and the base 1, and also to enhance the structural strength of the support ring 322.

[0047] like Figure 6 As shown, the support ring 322 may include an inclined portion 3224. The end of the inclined portion 3224 near the base 1 is inclined towards the center of the base 1, and the end of the inclined portion 3224 away from the base 1 is inclined away from the center of the base 1. Alternatively, the end of the support ring 322 connected to the base 1 has a first opening 3225, and the end of the support ring 322 connected to the frame portion 321 has a second opening 3226, with the first opening 3225 being smaller than the second opening 3226. The inclined portion 3224 enhances the structural strength of the support ring 322 and helps refract light from the light source onto the mounting surface, preventing dark spots on the mounting surface. Simultaneously, the inclined portion 3224 makes the support ring 322 appear thinner, thus making the LED lamp 100 appear thinner and improving the overall aesthetics of the LED lamp 100.

[0048] like Figure 3 As shown, the LED lamp 100 of the present invention employs a combined direct and indirect lighting method in its optical design. Specifically, the light emitted from the light source module 21 illuminates the surface through the light emitting portion 31, achieving direct lighting. Conversely, the light emitted from the light source module 21 illuminates the mounting surface through the edge portion 32, achieving indirect lighting. This combined direct and indirect lighting method allows the entire space to be illuminated with uniform brightness, avoiding dark or bright spots and improving the user's visual experience.

[0049] Specifically, the light emitted by the lamp beads 2112 of the LED lamp 100 passes through the lens 2121, and the lens 2121 converts the direct light emitted by the lamp beads 2112 into scattered light, that is, the lens 2121 can deflect the light emitted by the lamp beads 2112 to the center position of the LED lamp 100, and part of the light can irradiate the center position of the LED lamp 100, avoiding the dark area caused by the absence of light sources in the center position of the LED lamp 100, thereby making the light passing through the light exit portion 31 more uniform, and part of the light can pass through the support ring 322 and irradiate the mounting surface, avoiding dark spots on the mounting surface, thereby improving the overall lighting effect of the LED lamp 100. As an example, the light exit portion 31 adopts a plane panel with a haze of 15-60%; preferably, the light exit portion 31 adopts a plane panel with a haze of 20-55%; most preferably, the light exit portion 31 adopts a plane panel with a haze of 43%, and the test shows that the front light emission non-uniformity of the LED lamp 100 is less than 10%, that is, the maximum value (1435 Lux) and the minimum value (1293 Lux) of the light emission luminance of the light exit portion 31 differ by 9.89%, which is within 10%. When the light emission non-uniformity of the LED lamp 100 is less than 10%, the human vision will not perceive or will not obviously perceive the light emission non-uniformity of the LED lamp 100, thereby improving the visual experience and comfort of the user. Through the combination of the light exit portion 31 and the lens 2121, the light emission of the LED lamp 100 is ensured to be uniform, and the thickness of the LED lamp 100 is reduced. In the present application, the thickness of the LED lamp 100 is less than 95 mm; preferably, the thickness of the LED lamp 100 is less than 85 mm, and the support ring 322 adopts an inclined surface design, so that the LED lamp 100 appears more beautiful and thinner in vision due to the shape of the inclined surface.

[0050] As shown in Figure 3 The LED lamp 100 can also include a heat sink 4, which is arranged on the base 1. The heat sink 4 helps to dissipate heat from the LED lamp 100, thereby improving the light emission efficiency of the LED lamp 100 and ensuring stable operation of the LED lamp 100. The heat sink 4 can be arranged on the side of the base 1 facing the mounting surface, or on the side of the base 1 away from the mounting surface. In the present embodiment, the heat sink 4 is arranged on the side of the base 1 facing the mounting surface, that is, the heat sink 4 is arranged on the second surface 102 of the base 1. The heat sink 4 is arranged between the power supply module 22 and the base 1, and not only plays a role in dissipating heat, but also can isolate the power supply module 22 and the base 1, avoiding the conduction of current from the power supply module 22 to the base 1, and improving the safety of electricity use.

[0051] The shape of the heat sink 4 is the same as or similar to the shape of the power module 22 projected on the base 1, and the area of the heat sink 4 is greater than the area of the power module 22 projected on the base 1, so as to improve the heat dissipation effect of the heat sink 4, and the heat sink 4 can also ensure that the power module 22 and the base 1 are completely isolated, avoiding the power module 22 conducting current to the base 1, and further improving the safety of electricity use. The heat sink 4 can be a Mylar sheet or other component including a heat dissipation function. The Mylar sheet is soft, which is not only convenient to install, but also includes a certain buffering effect, reduces the noise generated by vibration when the power module 22 works, and the thickness of the Mylar sheet is thin, which can reduce the height of the LED lamp 100.

[0052] As shown in Figure 5 The side of the buffer 6 opposite to the mounting surface is in contact with the mounting surface, the buffer 6 can reduce the noise generated by vibration when the LED lamp 100 operates, and the noise generated by friction between the LED lamp 100 and the mounting surface, and can also avoid damage to the mounting surface caused by friction between the LED lamp 100 and the mounting surface. In other words, the LED lamp 100 is adapted to be mounted on the mounting surface, and the buffer 6 is arranged on the second surface 102 of the bottom wall 1, and the side of the buffer 6 opposite to the mounting surface is in contact with the mounting surface. The buffer 6 is arranged near the outer edge of the bottom wall 11, and the buffer 6 can be a material including a buffering effect such as foam or a silica gel pad, and the shape can be a cuboid, a cylinder or the like. The number of buffers 6 is preferably multiple, for example, three, and the multiple buffers 6 are uniformly distributed on the bottom wall 11, so as to improve the stability of the contact between the LED lamp 100 and the mounting surface.

It should be noted that in each embodiment, for the same LED lamp 100, the features such as "the optoelectronic module 2 can include the light source module 21 and the power module 22", "the light source module 21 and the power module 22 are arranged on the two sides of the base 1", "the lampshade 3 is arranged on the light emitting side of the light source module 21", "the light source module 21 is arranged between the base 1 and the lampshade 3", "the light source module 21 further includes the light source assembly 211 and the optical assembly 212", "the optical assembly 212 is arranged on the light emitting side of the light source assembly 211", "the lampshade 3 is arranged on the outer side of the optical assembly 212", "the optical assembly 212 is arranged between the lampshade 3 and the light source module 21" and the like can be applied individually or integrally in practice, so that only one feature is implemented or several features are implemented at the same time.

[0054] For example, the optoelectronic module 2 can include the light source module 21 and the power module 22, and the light source module 21 and the power module 22 are arranged on the two sides of the base 1.

[0055] For example, the lampshade 3 is arranged on the light emitting side of the light source module 21.
