Specific embodiments

[0038] Please refer to Figure 1 , is a schematic exploded view of a three-dimensional structure of an LED wall lamp provided by an embodiment of the present invention, wherein the LED wall lamp comprises a lamp body 10, a light source assembly 20 and a lens 30.

[0039] Please combine Figure 2-7The lamp body 10 has a receiving groove 110 facing away from the mounting surface, including a bottom side 120 and a top side 130 opposite to each other, and the width of the top side 130 is greater than the width of the bottom side 120; the light source assembly 20 includes a PCB board 210 and a plurality of LED lamp beads 220, the PCB board 210 is arranged at the bottom 1101 of the receiving groove 110, and the plurality of LED lamp beads 220 are distributed in multiple rows on a side of the PCB board 210 facing away from the bottom 1101 of the groove; the lens 30 is arranged in the receiving groove 110, including multiple rows of light-transmitting strips 310 and multiple rows of retaining walls 320, the multiple rows of light-transmitting strips 310 correspond one by one to the multiple rows of LED lamp beads 220, and the multiple rows of retaining walls 320 are respectively arranged on one side of the multiple rows of light-transmitting strips 310 close to the top side 130.

[0040] Specifically, the mounting surface here refers to the back side of the lamp body 10. Since the LED wall lamp is generally installed on a wall, the mounting surface is the side facing the wall, and the receiving groove 110 is opened on the side of the lamp body 10 away from the mounting surface. The shape of the lamp body 10 is generally a quadrilateral structure, and the bottom edge 120 and the top edge 130 are a pair of opposite edges. A side edge is also provided between the bottom edge 120 and the top edge 130. Here, the top edge 130 is the edge located at the upper part in the vertical wall direction, and the bottom edge 120 is the edge located at the lower part in the vertical wall direction. The width of the top edge 130 is greater than the width of the bottom edge 120, that is, the thickness of the lamp body 10 in the vertical wall direction is not the same. The thickness of the upper part of the lamp body 10 is greater than the thickness of the lower part of the lamp body 10, so that the opening direction of the receiving groove 110 is facing obliquely downward.

[0041] The PCB board 210 is detachably connected to the bottom 1101 of the receiving groove 110. The specific connection methods here include but are not limited to connection by screws, connection by bonding and connection by snap-on. The multiple LED lamp beads 220 are distributed in an array on the side of the PCB board 210 away from the bottom 1101 of the groove, and are arranged in multiple rows from the top to the bottom of the receiving groove 110. Since the opening direction of the receiving groove 110 is facing obliquely downward, when the light source assembly 20 is installed on the bottom 1101 of the receiving groove 110, most of the light it emits will also irradiate obliquely downward, that is, irradiate the ground under the wall.

[0042] The lens 30 is also provided above the PCB board 210 in the accommodating groove 110, so that the lens 30 can cover the light source assembly 20 therein, and the lens 30 is provided with multiple rows of light-transmitting strips 310 and multiple rows of retaining walls 320 spaced along the top to bottom direction of the accommodating groove 110, wherein the multiple rows of light-transmitting strips 310 correspond one-to-one to the multiple rows of LED lamp beads 220 thereunder, and the multiple rows of retaining walls 320 are respectively provided on one side of the multiple rows of light-transmitting strips 310 close to the top edge 130, that is, the retaining walls 320 are located above the light-transmitting strips 310, so that the retaining walls 320 are located between two adjacent rows of LED lamp beads 220. Here, the part of the light emitted by the LED lamp bead 220 that is irradiated to the light-transmitting strip 310 can be emitted outward through the light-transmitting strip 310, and the irradiation direction of this part of the light is obliquely downward; while the part of the light emitted by the LED lamp bead 220 that is irradiated to the baffle wall 320 is blocked by the baffle wall 320 and cannot pass through the baffle wall 320, so this part of the light will not be emitted.

[0043] In the embodiment of the present invention, the width of the top edge 130 of the lamp body 10 is greater than the width of the bottom edge 120, so that the light source assembly 20 can be installed obliquely downward, and the retaining wall 320 above the light-transmitting strip 310 can block the oblique upward light emitted by the obliquely installed light source assembly 20 and concentrate it to be emitted obliquely downward, thereby improving the overall lighting effect of the LED wall lamp.

[0044] Furthermore, in other preferred embodiments of the present invention, the light-transmitting strip 310 is an arc-shaped convex strip 3101 opening toward the LED lamp bead 220, and the retaining wall 320 is a V-shaped protrusion 3201 opening toward the PCB board 210; the end of the arc-shaped convex strip 3101 close to the top edge 130 is connected to the end of the V-shaped protrusion 3201 close to the bottom edge 120.

[0045] Specifically, the cross-sectional shape of the arc ridge 3101 is an arc, wherein the arc opening direction is toward the LED lamp bead 220, and the two ends of the arc are in contact with the PCB board 210, thereby covering the LED lamp bead 220 in the arc ridge 3101. Since the light-transmitting strip 310 is arranged along the width direction of the PCB board 210, a plurality of LED lamp beads 220 in a row share one arc ridge 3101; the V-shaped protrusion 3201 is arranged above the arc ridge 3101, wherein the end of the V-shaped protrusion 3201 close to the bottom edge 120 is connected to the end of the arc ridge 3101 close to the top edge 130, thereby making the V-shaped opening direction of the V-shaped protrusion 3201 face the PCB board 210, and the side away from the PCB board 210 is a block-shaped protrusion protruding outward. Here, the arc opening of the arc convex strip 3101 is larger than the size of the LED lamp bead 220, so that the arc convex strip 3101 can completely cover the LED lamp bead 220 therein, and the LED lamp bead 220 can also be covered therein after the lens 30 is deformed by thermal expansion and contraction; and designing the V-shaped protrusion 3201 into a V-shaped opening structure can also make the lens 30 have a certain ability to resist deformation due to thermal expansion and contraction, and further ensure that the light-transmitting strip 310 can always cover the LED lamp bead 220 therein.

[0046] Furthermore, in other preferred embodiments of the present invention, the thickness of the arc-shaped convex strip 3101 gradually increases from an end close to the top edge 130 to an end far from the top edge 130 to form a polarized light distribution.

[0047] Specifically, the thickness of the arc-shaped convex strip 3101 along the arc length direction of the arc structure is not the same, but gradually increases from top to bottom, that is, gradually increases from the end close to the top edge 130 to the end away from the top edge 130. Such a design can form a polarized light distribution, that is, the original Lambertian light distribution of the LED light source is designed to be a polarized light distribution, so that more LED light is controlled in the lower area of ​​the lamp, and the irradiated circular area is changed into an elliptical area similar to a rectangle, such as Figure 8 The figure shows the light distribution curve of the lens of the embodiment of the present invention, which can ensure that the light emitted by the LED lamp bead 220 is transmitted through the arc-shaped convex strip 3101 and then irradiated obliquely downward, that is, it can ensure that the part of the light emitted by the LED lamp bead 220 that irradiates the light-transmitting strip 310 can pass through the light-transmitting strip 310 and irradiate the bottom surface obliquely downward, thereby increasing the effective irradiation area of ​​the LED wall lamp.

[0048] Furthermore, in other preferred embodiments of the present invention, a plurality of light-blocking serrations 3202 are provided on the outer surface of the V-shaped protrusion 3201 facing the top edge 130 .

[0049] Specifically, the outer surface of the V-shaped protrusion 3201 facing away from the PCB board 210 is not flat. Here, the V-shaped protrusion 3201 has three outer surfaces facing away from the PCB board 210, namely, the outer surface facing the top edge 130, the outer surface facing the bottom edge 120, and a side completely facing away from the PCB board 210 between the two. Here, the light-blocking serrations 3202 are arranged on the outer surface of the V-shaped protrusion 3201 facing the top edge 130. The light-blocking serrations 3202 can enhance the shielding effect of the light emitted by the LED lamp bead 220 that illuminates the V-shaped protrusion 3201.

[0050] Furthermore, in other preferred embodiments of the present invention, the lens 30 also includes a plurality of connecting portions 330 , and the end of the arc-shaped ridge 3101 away from the top edge 130 and the end of the V-shaped ridge 3201 close to the top edge 130 are both connected to one of the connecting portions 330 .

[0051] Here, the connecting portion 330 can be regarded as the remaining part of the lens 30 except the arc-shaped convex strip 3101 and the V-shaped convex block 3201. The arc-shaped convex strip 3101, the V-shaped convex block 3201 and the connecting portion 330 are an integrated structure, and a plurality of the arc-shaped convex strips 3101 and the V-shaped convex block 3201 are connected into one piece through a plurality of the connecting portions 330. As described above, the opposite ends of the arc-shaped convex strips 3101 and the V-shaped convex block 3201 are connected together, and a connecting portion 330 is connected to the outer side of each group of the arc-shaped convex strips 3101 and the V-shaped convex block 3201.

[0052] Furthermore, in other preferred embodiments of the present invention, the lens 30 also includes a plurality of connecting columns 340, and the connecting columns 340 are arranged on the side facing the PCB board 210; a plurality of connecting plates 140 are arranged at positions of the groove bottom 1101 corresponding to the plurality of connecting columns 340; and the connecting columns 340 pass through the PCB board 210 to be connected to the connecting plates 140.

[0053] Specifically, the plurality of connecting posts 340 are located on the side of the lens 30 away from the light-transmitting strip 310 and the retaining wall 320, the connecting posts 340 extend toward the PCB board 210, and the PCB board 210 is provided with through holes for the connecting posts 340 to pass through, and the bottom 1101 of the groove is provided with a plurality of connecting plates 140 at positions corresponding to the plurality of connecting posts 340, and the ends of the connecting posts 340 passing through the PCB board 210 can be detachably connected to the connecting plates 140, thereby completing the connection between the lens 30 and the lamp body 10.

[0054] In addition, in other preferred embodiments of the present invention, the connecting piece 140 is arranged in the groove 1102 of the groove bottom 1101, and has a center hole 1401 and a plurality of barbs 1402 extending toward the center hole 1401; the end of the connecting column 340 passing through the PCB board 210 is provided with anti-slip grooves (not shown in the figure), and can be inserted into the center hole 1401 and abut against the barbs 1402.

[0055] Specifically, the connecting piece 140 is embedded in the groove 1102 at the bottom 1101 of the groove, and has a center hole 1401 at its center position, the aperture of which is slightly smaller than the diameter of the end of the connecting column 340. A plurality of barbs 1402 are arranged around the center hole 1401, extending toward the center hole 1401 and tilted away from the connecting column 340, so that the connecting column 340 can pass through the center hole 1401 and abut against the plurality of barbs 1402 under the action of external force. The barbs 1402 prevent the end of the connecting column 340 from falling out of the center hole 1401, thereby making the connection between the lens 30 and the lamp body 10 more reliable.

[0056] Here, by providing the anti-slip groove at the end of the connecting column 340 passing through the PCB board 210, the resistance of the end of the connecting column 340 to escape from the center hole 1401 can be increased, further making the connection between the lens 30 and the lamp body 10 more reliable.

[0057] Furthermore, in other preferred embodiments of the present invention, a glue groove 350 with an opening toward the groove bottom 1101 is provided along the outer circumference of the lens 30, and a structural glue (not shown in the figure) for sealing and connecting and fixing is provided in the glue groove 350.

[0058] Specifically, the glue groove 350 is arranged along the outer circumference of the lens 30, and the opening direction of the glue groove 350 is toward the bottom 1101 of the groove. Structural glue is applied in the glue groove 350. The structural glue has strong connection and fixing performance and sealing performance. On the one hand, it can further improve the reliability of the connection between the lens 30 and the lamp body 10, and on the other hand, it can form a relatively closed space between the lens 30 and the lamp body 10. The light source assembly 20 is arranged in the closed space, which helps to improve the service life of the light source assembly 20.

[0059] Further, in other preferred embodiments of the present invention, the LED wall lamp further comprises a base 40 and a power supply 50 electrically connected to the PCB board 210, the base 40 has a power supply slot 410 opening toward the lamp body 10, the power supply 50 is arranged on a side of the bottom 1101 of the slot away from the PCB board 210, and is accommodated in the power supply slot 410;

[0060] A clamping protrusion 420 is provided on one side of the slot wall of the power slot 410, and a fixing hole 1301 for accommodating the clamping protrusion 420 is provided on the top edge 130 opposite to the clamping protrusion 420;

[0061] A slot wall of the power slot 410 opposite to the locking protrusion 420 is fixed to the bottom edge 120 by means of screws 60 .

[0062] Specifically, the bottom of the power slot 410 is fixedly connected to the wall by screws and other fixings, and the opening of the power slot 410 faces the side of the slot bottom 1101 away from the PCB board 210, and is used to cover the power supply 50 fixedly connected to the side of the slot bottom 1101 away from the PCB board 210 to protect it. Here, the power supply 50 is set on the power supply rack 510, and the power supply rack 510 is fixedly connected to the side of the slot bottom 1101 away from the PCB board 210 by screws.

[0063] As shown in the figure, the latching protrusion 420 is arranged on one side groove wall of the power groove 410, and the fixing hole 1301 for accommodating the latching protrusion 420 is also arranged on the top edge 130 opposite to the side groove wall. When the latching protrusion 420 is engaged in the fixing hole 1301, the connection between one side of the power groove 410 and one side of the lamp body 10 can be completed; a screw hole is provided on the other side groove wall of the power groove 410 opposite to the latching protrusion 420, and the screw 60 can form a fixed connection between the bottom edge 120 and the screw hole, thereby completing the connection between the other side of the power groove 410 and the other side of the lamp body 10. In this way, the connection between the lamp body 10 and the base 40 is completed, that is, the lamp body 10 can be quickly installed on the wall.

[0064] Further, in other preferred embodiments of the present invention, a connecting plate 150 extending toward the base 40 is provided on a side of the bottom 1101 of the slot away from the PCB board 210, and the shape of the connecting plate 150 matches the shape of the power slot 410;

[0065] A positioning groove 4101 is provided at the top of the power groove 410 , and one end of the connecting plate 150 away from the groove bottom 1101 can be inserted into the positioning groove 4101 , and a sealing ring 4102 is provided in the positioning groove 4101 .

[0066] Specifically, the connecting plate 150 is arranged on the side of the groove bottom 1101 away from the PCB board 210, and is an annular structure matching the shape of the power groove 410; the positioning groove 4101 is arranged at the groove top of the power groove 410, and the sealing ring 4102 is provided in the positioning groove 4101. When the lamp body 10 is connected to the base 40, the end of the connecting plate 150 away from the groove bottom 1101 can be inserted into the positioning groove 4101, so that the power groove 410 and the side of the groove bottom 1101 away from the PCB board 210 form a relatively closed accommodating space for accommodating the power supply 50, and the sealing ring 4102 can improve the airtightness of the accommodating space, thereby further improving the safety of use of the power supply 50.
