Specific Implementation

[0038] Please refer to Figure 1 This is an exploded three-dimensional structural diagram of an LED wall lamp provided by an embodiment of the present utility model. The LED wall lamp includes 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 edge 120 and a top edge 130, the width of the top edge 130 being greater than the width of the bottom edge 120; the light source assembly 20 includes a PCB board 210 and a plurality of LED beads 220, the PCB board 210 being disposed at the bottom 1101 of the receiving groove 110, and the plurality of LED beads 220 being arranged in multiple rows on the side of the PCB board 210 facing away from the bottom 1101 of the groove; the lens 30 is disposed in the receiving groove 110, including multiple rows of light-transmitting strips 310 and multiple rows of baffles 320, the multiple rows of light-transmitting strips 310 corresponding one-to-one with the multiple rows of LED beads 220, and the multiple rows of baffles 320 being disposed on the side of the multiple rows of light-transmitting strips 310 near the top edge 130.

[0040] Specifically, the mounting surface here refers to the back 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. The receiving groove 110 is opened on the side of the lamp body 10 away from the mounting surface. The lamp body 10 is generally a quadrilateral structure. 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 upper edge in the vertical wall direction, while the bottom edge 120 is the lower edge 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 faces diagonally downward.

[0041] The PCB board 210 is detachably connected to the bottom 1101 of the receiving groove 110. The specific connection methods include, but are not limited to, screw connection, adhesive connection, and snap-on connection. Multiple LED beads 220 are arrayed on the side of the PCB board 210 facing away from the bottom 1101 of the groove and arranged in multiple rows along the top to bottom direction of the receiving groove 110. Since the opening of the receiving groove 110 faces obliquely downward, when the light source assembly 20 is installed on the bottom 1101 of the receiving groove 110, most of the light emitted by it will also shine obliquely downward, that is, shine on the ground below the wall.

[0042] A lens 30 is also provided above the PCB board 210 in the receiving groove 110, so that the lens 30 can cover the light source assembly 20 therein. The lens 30 has multiple rows of light-transmitting strips 310 and multiple rows of baffles 320 spaced apart along the top to bottom direction of the receiving groove 110. The multiple rows of light-transmitting strips 310 correspond one-to-one with the multiple rows of LED beads 220 below them. The multiple rows of baffles 320 are respectively located on the side of the multiple rows of light-transmitting strips 310 near the top edge 130, that is, the baffles 320 are located above the light-transmitting strips 310, so that the baffles 320 are located between two adjacent rows of LED beads 220. Here, the portion of the light emitted by the LED bead 220 that illuminates the light-transmitting strip 310 can pass through the light-transmitting strip 310 and be emitted outwards, with the direction of this portion of light being obliquely downwards; however, the portion of the light emitted by the LED bead 220 that illuminates the barrier wall 320 is blocked by the barrier wall 320 and cannot pass through the barrier wall 320, so this portion of light will not be emitted.

[0043] In this embodiment of the utility model, 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. Furthermore, the baffle 320 above the light-transmitting strip 310 can block the upward light emitted by the obliquely installed light source assembly 20, concentrating it to be emitted obliquely downward, thereby improving the overall lighting effect of the LED wall lamp.

[0044] Furthermore, in other preferred embodiments of this utility model, the light-transmitting strip 310 is an arc-shaped protrusion 3101 with an opening facing the LED lamp bead 220, and the barrier 320 is a V-shaped protrusion 3201 with an opening facing the PCB board 210; the end of the arc-shaped protrusion 3101 near the top edge 130 is connected to the end of the V-shaped protrusion 3201 near the bottom edge 120.

[0045] Specifically, the cross-sectional shape of the arc-shaped protrusion 3101 is arc-shaped, with the arc opening facing the LED bead 220. The two ends of the arc abut against the PCB board 210, thereby covering the LED bead 220 inside the arc-shaped protrusion 3101. Since the light-transmitting strip 310 is arranged along the width direction of the PCB board 210, multiple LED beads 220 in a row share one arc-shaped protrusion 3101. The V-shaped protrusion 3201 is arranged above the arc-shaped protrusion 3101, with the end of the V-shaped protrusion 3201 near the bottom edge 120 connected to the end of the arc-shaped protrusion 3101 near the top edge 130, so that the V-shaped opening of the V-shaped protrusion 3201 faces the PCB board 210, while its side away from the PCB board 210 is an outwardly protruding block. Here, the arc-shaped opening of the arc-shaped protrusion 3101 is larger than the size of the LED bead 220, so that the arc-shaped protrusion 3101 completely covers the LED bead 220. Similarly, even after the lens 30 undergoes thermal expansion and contraction deformation, it can still cover the LED bead 220. Designing the V-shaped protrusion 3201 as a V-shaped opening structure can also give the lens 30 a certain ability to resist thermal expansion and contraction deformation, further ensuring that the light-transmitting strip 310 can always cover the LED bead 220.

[0046] Furthermore, in other preferred embodiments of this utility model, the thickness of the arc-shaped protrusion 3101 gradually increases from the end near the top edge 130 to the end away from the top edge 130, so as to form a light distribution with a polarized shape.

[0047] Specifically, the thickness of the arc-shaped protrusion 3101 is not uniform along the arc length of the arc structure, but gradually increases from top to bottom, that is, from the end near the top edge 130 to the end away from the top edge 130. This design can form a polarized light distribution, that is, the original Lambertian light distribution of the LED light source is designed as a polarized light distribution, controlling more LED light in the lower area of ​​the lamp, and at the same time changing the illuminated circular area into an elliptical area similar to a rectangle, such as... Figure 8 The diagram shown is a light distribution curve of the lens in this embodiment of the present invention. It can ensure that the light emitted by the LED lamp bead 220 is transmitted through the arc-shaped convex strip 3101 and shines obliquely downward. That is, it can ensure that the part of the light emitted by the LED lamp bead 220 that shines on the light-transmitting strip 310 can shine through the light-transmitting strip 310 and shine on the bottom surface obliquely downward, thereby increasing the effective illumination area of ​​the LED wall lamp.

[0048] Furthermore, in other preferred embodiments of this utility model, the V-shaped protrusion 3201 is provided with a plurality of light-blocking serrations 3202 on the outer surface 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. There are three sides of the V-shaped protrusion 3201 facing away from the outer surface of the PCB board 210: the outer surface facing the top edge 130, the outer surface facing the bottom edge 120, and the side between the two that is completely facing away from the PCB board 210. Here, the light-blocking sawtooth 3202 is provided on the outer surface of the V-shaped protrusion 3201 facing the top edge 130. The light-blocking sawtooth 3202 can improve the blocking effect of the light emitted by the LED lamp bead 220 hitting the V-shaped protrusion 3201.

[0050] Furthermore, in other preferred embodiments of the present invention, the lens 30 further includes a plurality of connecting portions 330, wherein the end of the arc-shaped protrusion 3101 away from the top edge 130 and the end of the V-shaped protrusion 3201 near the top edge 130 are each connected to a connecting portion 330.

[0051] Here, the connecting portion 330 can be considered as the remaining part of the lens 30 excluding the arc-shaped protrusion 3101 and the V-shaped protrusion 3201. The arc-shaped protrusion 3101, the V-shaped protrusion 3201, and the connecting portion 330 are an integral structure, and multiple arc-shaped protrusions 3101 and V-shaped protrusions 3201 are connected into one piece by multiple connecting portions 330. As described above, the opposite ends of the arc-shaped protrusions 3101 and the V-shaped protrusions 3201 are connected together, and a connecting portion 330 is connected to the outer side of each group of arc-shaped protrusions 3101 and V-shaped protrusions 3201.

[0052] Furthermore, in other preferred embodiments of this utility model, the lens 30 further includes a plurality of connecting posts 340, the connecting posts 340 being disposed on the side facing the PCB board 210; the bottom 1101 of the groove is provided with a plurality of connecting pieces 140 at positions corresponding to the plurality of connecting posts 340; the connecting posts 340 pass through the PCB board 210 and are connected to the connecting pieces 140.

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

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

[0055] Specifically, the connecting piece 140 is embedded in the groove 1102 at the bottom of the slot 1101, and has a central hole 1401 at its center with a diameter slightly smaller than the diameter of the end of the connecting post 340. A plurality of barbs 1402 are arranged around the central hole 1401, extending toward the central hole 1401 and tilting away from the connecting post 340, so that the connecting post 340 can pass through the central hole 1401 under the action of external force and abut against the plurality of barbs 1402. The barbs 1402 have the function of preventing the end of the connecting post 340 from coming out of the central hole 1401, which makes the connection between the lens 30 and the lamp body 10 more reliable.

[0056] Here, by providing the anti-slip texture at the end of the connecting post 340 that passes through the PCB board 210, the resistance of the connecting post 340 end to disengage from the central 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 this utility model, a glue groove 350 with an opening facing the bottom 1101 of the groove is provided around the outer circumference of the lens 30, and the glue groove 350 is provided with structural adhesive (not shown in the figure) for sealing and connection.

[0058] Specifically, the adhesive groove 350 is arranged around the outer circumference of the lens 30, and the opening direction of the adhesive groove 350 is towards the bottom 1101 of the groove. Structural adhesive is applied inside the adhesive groove 350. The structural adhesive has strong bonding 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. 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 placed in this closed space, which helps to improve the service life of the light source assembly 20.

[0059] Furthermore, in other preferred embodiments of the present invention, the LED wall lamp further includes a base 40 and a power supply 50 electrically connected to the PCB board 210. The base 40 has a power supply slot 410 with an opening facing the lamp body 10. The power supply 50 is disposed on the side of the bottom 1101 of the slot away from the PCB board 210 and is housed in the power supply slot 410.

[0060] The power supply slot 410 has a latching protrusion 420 on one side of the slot wall, and the top edge 130 opposite to the latching protrusion 420 has a fixing hole 1301 for accommodating the latching protrusion 420.

[0061] The side wall of the power supply slot 410 opposite to the card protrusion 420 is fixed to the bottom edge 120 by screws 60.

[0062] Specifically, the bottom of the power supply slot 410 is fixedly connected to the wall by screws or other fasteners. The opening of the power supply slot 410 faces the side of the slot bottom 1101 away from the PCB board 210, which is used to cover the power supply 50 fixedly connected to the side of the slot bottom 1101 away from the PCB board 210, so as to protect it. Here, the power supply 50 is set on the power supply bracket 510, and the power supply bracket 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 provided on one side of the power supply slot 410, and the top edge 130 opposite to this side of the slot wall is also provided with a fixing hole 1301 for accommodating the latching protrusion 420. When the latching protrusion 420 is engaged in the fixing hole 1301, the connection between one side of the power supply slot 410 and one side of the lamp body 10 is completed. A screw hole is provided on the other side of the power supply slot 410 opposite to the latching protrusion 420. 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 supply slot 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] Furthermore, in other preferred embodiments of this utility model, the bottom 1101 of the slot is provided with a connecting plate 150 extending toward the base 40 on the side opposite to the PCB board 210, and the shape of the connecting plate 150 matches the shape of the power slot 410.

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

[0066] Specifically, the connecting plate 150 is located on the side of the bottom 1101 of the slot that faces away from the PCB board 210, and is an annular structure that matches the shape of the power supply slot 410; the positioning slot 4101 is located at the top of the power supply slot 410, and the sealing ring 4102 is provided in the positioning slot 4101. When the lamp body 10 is connected to the base 40, the end of the connecting plate 150 away from the bottom 1101 of the slot can be inserted into the positioning slot 4101, so that the power supply slot 410 and the side of the bottom 1101 of the slot that faces away from the PCB board 210 form a relatively sealed receiving space to accommodate the power supply 50. The sealing ring 4102 can improve the airtightness of the receiving space and further improve the safety of the power supply 50.
