[0041] like Figures 1 to 3 and Fig.15As shown, according to an embodiment of the utility model, an LED lamp with a side-lighting effect includes: a mounting base 100, a lamp body 200 and a side-lighting component 300, the lamp body 200 is connected to the mounting base 100, the side-lighting component 300 is connected to the lamp body 200, the side-lighting component 300 includes a connecting piece 310 connected to the back side of the lamp body 200 and a first light source 320 capable of emitting light to the side of the connecting piece 310, and the connecting piece 310 is provided with a plurality of lens portions 311 for the light emitted by the first light source 320 to pass through.

[0042] When the LED lamp with side-lighting effect in this embodiment is in use, light is emitted downward through the lamp body 200, and at the same time, the first light source 320 in the side-lighting assembly 300 emits light sideways, and the light emitted by the first light source 320 passes through the multiple lens portions 311 of the connecting piece 310 and is emitted toward the side of the lamp body 200, illuminating the side of the lamp body 200, and the light emitted after passing through the multiple lens portions 311 is irradiated on the ceiling and other wall surfaces, illuminating the surroundings of the lamp body 200, and the light emitted after passing through the multiple lens portions 311 is also refracted or scattered downward through the ceiling, etc., so that the overall brightness difference of the LED lamp is reduced, the brightness of the light is more evenly distributed in the room, glare is reduced, and the overall lighting effect of the LED lamp is better.

[0043] When the lamp body 200 is connected to the mounting base 100 , the connector 310 on the back side of the lamp body 200 can fill the gap between the back side of the lamp body 200 and the ceiling, making the LED lamp with side-emitting effect more beautiful during installation.

[0044] Reference Figures 5 and 6 In some embodiments of the utility model, the first light source 320 includes a first light bar 321 that can be installed in the connecting member 310, and the first light bar 321 is provided with lamp beads 322. The connecting member 310 is provided with a groove 312 that can position the first light bar 321, and the lower side of the groove 312 is an opening. The setting of the groove 312 facilitates the installation of the first light bar 321. Since the connecting member 310 is arranged on the back side of the lamp body 200, when the lower side of the groove 312 is an opening, the first light bar 321 and the plurality of lamp beads 322 are covered between the groove 312 of the connecting member 310 and the back side of the lamp body 200. The connecting member 310 cooperates with the back side of the lamp body 200 to protect the first light bar 321 and the plurality of lamp beads 322, and prolong the service life of the first light bar 321 and the plurality of lamp beads 322.

[0045] It is conceivable that the first light bar 321 can be attached to the inner side of the connecting member 310 . In this manner, the light emitted by the lamp beads 322 can be emitted from the lens portion 311 to the side of the lamp body 200 .

[0046] Reference Figures 5 and 6 In some embodiments of the present invention, a first positioning protrusion 313 is provided on the wall surface of the groove 312 close to the lens portion 311 , and a positioning groove 314 capable of positioning the lamp bead 322 is formed between the two first positioning protrusions 313 located on both sides of any lens portion 311 . When the first light source 320 needs to be installed in the connecting piece 310, the first light bar 321 is first bent so that the shape of the first light bar 321 matches the shape of the groove 312 of the connecting piece 310, and then the lamp beads 322 of the first light bar 321 are aligned with the positioning groove 314, and the first light bar 321 is moved toward the groove 312 so that the first light bar 321 is inserted into the groove 312, and the lamp beads 322 are positioned through the positioning groove 314 so that the lamp beads 322 correspond to the lens portion 311 to form a reference for workers to assemble, and at the same time, the light emitted by the lamp beads 322 can be emitted from the lens portion 311 to illuminate the surrounding area of ​​the lamp body 200, and the light is refracted or scattered downwardly through the ceiling, etc., so that the overall brightness difference of the LED lamp is reduced, the brightness of the light is more evenly distributed in the room, glare is reduced, and the overall light output effect of the LED lamp is better. At the same time, the two first positioning protrusions 313 on the two adjacent sides of any lens portion 311 can also prevent the lamp beads 322 from escaping from the left and right directions of the positioning grooves 314 and being misaligned with the lens portion 311 when the first light bar 321 slides, which facilitates workers to assemble in the factory and improves the yield rate.

[0047] Reference Figures 5 and 6 In some embodiments of the utility model, the wall surface of the groove 312 away from the lens portion 311 is provided with a second positioning protrusion 315 that can cooperate with the plurality of first positioning protrusions 313 to position the first light bar 321. A gap is formed between the plurality of first positioning protrusions 313 and the plurality of second positioning protrusions 315 for the first light bar 321 to fit into, and the plurality of first positioning protrusions 313 cooperate with the plurality of second positioning protrusions 315 to position the first light bar 321.

[0048] Specifically, the first positioning protrusion 313 and the second positioning protrusion 315 are staggered to facilitate the installation of the first light bar 321 and prevent the first light bar 321 from falling off the connecting member 310. It can be understood that the connecting member 310, the plurality of first positioning protrusions 313 and the plurality of second positioning protrusions 315 are an integral structure formed in one piece, and the integral forming makes processing more convenient.

[0049] Reference Figures 5 and 6In some embodiments of the present invention, a plurality of lens portions 311 are arranged at intervals along the circumference of the outer surface of the connecting member 310. Since each lens portion 311 is arranged at intervals along the circumference of the outer surface of the connecting member 310, the light emitted outward through the lens portion 311 is more uniform, illuminating the surrounding area of ​​the lamp body 200, and also refracting or scattering the light downward through the ceiling, etc., so that the overall brightness difference of the LED lamp is reduced, the brightness of the light is more evenly distributed in the room, glare is reduced, and the overall light output effect of the LED lamp is better.

[0050] Reference Figures 5 and 6 In some embodiments of the utility model, the lens portion 311 is an arc-shaped protrusion protruding from the outer surface of the connecting member 310, which can expand the range of light emitted by the lens portion 311. The lamp beads 322 correspond one-to-one with the lens portion 311, so that the overall light-emitting effect of the LED lamp is better. Since the lamp beads 322 correspond one-to-one with the lens portion 311, the lens portion 311 serves as a reference, which is convenient for workers to assemble.

[0051] Reference Figure 1 to Figure 2 In some embodiments of the present invention, the connector 310 is detachably connected to the lamp body 200 by means of screws 330. The connector 310 can be quickly installed to the lamp body 200 by means of screws 330, and the operation is simple, and it is convenient to install and remove.

[0052] Reference Figures 7 to 9 In some embodiments of the utility model, the mounting seat 100 is provided with a snap-in groove 110, the lamp body 200 is rotatably mounted on the mounting seat 100, and the lamp body 200 is provided with a snap-in portion 211 that can snap into or out of the snap-in groove 110 following the rotation thereof. When the lamp body 200 needs to be mounted on the mounting seat 100, the lamp body 200 is adjusted so that the snap-in portion 211 is aligned with the snap-in groove 110 of the mounting seat 100, and then the lamp body 200 is rotated. When the lamp body 200 rotates, the snap-in portion 211 on the lamp body 200 follows the rotation, and the snap-in portion 211 is gradually snapped into the snap-in groove 110. At this time, the lamp body 200 is snap-fitted and fixed on the mounting seat 100. When the lamp body 200 needs to be removed from the mounting base 100, the lamp body 200 is rotated in the opposite direction. At this time, the clamping part 211 of the lamp body 200 gradually disengages from the clamping groove 110 until the clamping part 211 is separated from the clamping groove 110. The fixation between the lamp body 200 and the mounting base 100 is released, and the lamp body 200 can be removed from the mounting base 100.

[0053] It can be imagined that the number of the snap-in groove 110 and the snap-in portion 211 is 1, 2, etc. When the snap-in groove 110 and the snap-in portion 211 are one, the lamp body 200 can be connected to the mounting base 100. When the snap-in groove 110 and the snap-in portion 211 are 2 or more, the snap-in groove 110 can be arranged along the circumference of the mounting base 100, and the snap-in portion 211 can be arranged along the circumference of the lamp body 200, which can make the connection between the body 200 and the mounting base 100 more stable.

[0054] It is conceivable that the mounting base 100 and the lamp body 200 are connected by means of a snap-fit, and the mounting base 100 and the lamp body 200 can also be connected by means of screw connection or the like.

[0055] Reference Figures 8 to 9 In some embodiments of the present invention, the inner wall of the clamping groove 110 is further provided with a downwardly recessed positioning groove 111, and the clamping portion 211 is provided with a positioning protrusion 2111 that can cooperate with the positioning groove 111 for positioning. The positioning protrusion 2111 is an arc-shaped protrusion, and the positioning groove 111 is an arc-shaped surface. When the lamp body 200 needs to be removed from the mounting seat 100, the user needs to apply a certain force so that the positioning protrusion 2111 is squeezed out of the positioning groove 111. The cooperation between the positioning protrusion 2111 and the positioning groove 111 makes it more stable when the lamp body 200 is clamped and fixed to the mounting seat 100.

[0056] Reference Fig.10 In some embodiments of the utility model, the lamp body 200 includes a lampshade 230 and a shell 210 detachably connected to the back side of the mounting base 100, the shell 210 is configured with a second light source, the shell 210 is provided with a protruding upper limit portion 212, the shell 210 is detachably connected to a fixing member 220, the fixing member 220 is provided with a protruding lower limit portion 221, and a gap is formed between the lower limit portion 221 and the upper limit portion 212 for positioning the lampshade 230. When the lamp body 200 is installed, the lampshade 230 is placed on the fixing part 220, and the lower limit part 221 of the fixing part 220 can cooperate with the upper limit part 212 of the shell 210 to form a gap for the lampshade 230 to move. When the lampshade 230 moves toward the shell 210, the upper surface of the lampshade 230 can abut against the upper limit part 212 to limit the upper limit of the movement of the lampshade 230, and the external force on the lampshade 230 is cancelled. The lampshade 230 moves toward the fixing part 220 under the action of gravity, and the lower surface of the lampshade 230 abuts against the lower limit part 221 to limit the lower limit of the movement of the lampshade 230.

[0057] Reference Figures 13 to 14Specifically, the housing 210 is provided with a first supporting portion 214 that is protruding and arranged in an annular shape, and the fixing member 220 is provided with a second supporting portion 223 that can support the first supporting portion 214 to prevent the fixing member 220 from moving. When the fixing member 220 moves relative to the housing 210 and the second supporting portion 223 supports the first supporting portion 214, the fixing member 220 is supported against the housing 210, and the fixing member 220 cannot continue to move upward relative to the housing 210.

[0058] Reference Figure 11 to Figure 12 The outer wall of the housing 210 is provided with a plurality of engaging positions 213, and the fixing member 220 is also provided with a plurality of engaging blocks 222 which are arranged at intervals along the circumferential direction of the inner wall thereof and can be engaged with or disengaged from the engaging positions 213. When the fixing member 220 and the lampshade 230 need to be installed to the housing 210, the plurality of engaging blocks 222 of the fixing member 220 are misaligned with the plurality of engaging positions 213 of the housing 210, and then the fixing member 220 is moved so that the fixing member 220 moves toward the housing 210, and then the fixing member 220 is rotated until the plurality of engaging blocks 222 are aligned with the plurality of engaging positions 213, and then the fixing member 220 is released, and the fixing member 220 slides relative to the housing 210 under the action of gravity, and the engaging blocks 222 are engaged with the engaging positions 213, and at this time, the fixing member 220 and the housing 210 are engaged with each other. When it is necessary to remove the fixing member 220 and the lampshade 230 from the housing 210, the fixing member 220 is pushed upward, and the clamping block 222 of the fixing member 220 gradually disengages from the clamping position 213, and then the fixing member 220 is rotated in the opposite direction, so that the clamping block 222 is misaligned with the clamping position 213, and the fixing member 220 and the lampshade 230 can be removed from the housing 210. It can be understood that the housing 210 and the fixing member 220 can be connected in a buckle manner.
