[0035] The present invention will be further described in detail below with reference to the accompanying drawings.

[0036] See also Figures 1 to 3 , a wall lamp provided by an embodiment of the present invention includes a housing 100, a first light source assembly 200 and a second light source assembly 300, wherein the housing 100 defines a mounting cavity 110, the mounting cavity 110 forms a first light outlet 112 at the lower end of the housing 100, and the mounting cavity 110 forms a second light outlet 113 at the upper end of the housing 100. The inner wall of the housing 100 is integrally provided with a heat sink 120, and the heat sink 120 is located on the left and right sides of the inner wall of the housing 100, but is not limited to being provided only on the two sides of the inner wall of the housing 100. For example, the heat sink 120 can also be provided on the front and / or rear side of the inner wall of the housing 100, with the lower end of the heat sink 120 extending toward the first light outlet 112, and the upper end of the heat sink 120 extending toward the second light outlet 113. Of course, the heat sink 120 can also be provided in other structural forms. The first light source assembly 200 is assembled and connected to the end of the heat sink 120 close to the first light outlet 112 , and the second light source assembly 300 is assembled and connected to the end of the heat sink 120 close to the second light outlet 113 .

[0037] During use, the first light source assembly 200 shines light downward through the first light outlet 112, thereby illuminating the ground; at the same time, the second light source assembly 300 shines light upward through the second light outlet 113, thereby illuminating the wall. A heat sink 120 is integrally provided on the inner wall of the housing 100, and the heat sink 120 is connected between the first light source assembly 200 and the second light source assembly 300. With this arrangement, the heat sink 120 quickly absorbs the heat emitted by the first light source assembly 200 and the second light source assembly 300, and dissipates the heat to the external environment through the housing 100, thereby reducing the temperature of the first light source assembly 200 and the second light source assembly 300, that is, avoiding excessive temperature in the installation cavity 110, thereby ensuring the service life of the wall lamp.

[0038] Furthermore, both ends of the heat sink 120 serve as mounting bosses, and thus the heat sink 120 facilitates the mounting of the first light source assembly 200 and the second light source assembly 300 on the inner side of the housing 100 .

[0039] In addition, the wall lamp adopts the above-mentioned heat dissipation structure instead of setting a heat dissipation plate specifically on the inside of the wall lamp. This arrangement saves the space occupied by the inside of the wall lamp, so that the first light source assembly 200, the second light source assembly 300 and the power supply 500 can be easily installed in the limited space of the wall lamp.

[0040] In some embodiments, reference Figure 2 and Figure 4 The wall lamp also includes a mounting base 400, which is attached to the upper end of the heat sink 120. The second light source assembly 300 is disposed on a side of the mounting base 400 near the second light outlet 113. The mounting base 400 is used to mount the wall lamp's power supply 500. It is understood that the heat sink 120 acts as a mounting boss, and the mounting base 400 can be mounted on the inner side of the housing 100 via the heat sink 120. Simultaneously, the second light source assembly 300 and the wall lamp's power supply 500 are both mounted on the mounting base 400. Thus, the second light source assembly 300 and the power supply 500 are conveniently mounted within the housing 100 via the mounting base 400.

[0041] The mounting base 400 can be made of a material with good thermal conductivity, such as metal. The second light source assembly 300 includes at least a second light source board 310 and a second light-transmitting plate 320. The second light source board 310 is attached to the mounting base 400. The second light-transmitting plate 320 can be an anti-glare plate. The second light-transmitting plate 320 is positioned near the second light outlet 113, i.e., adjacent to the second light outlet 113. During use, the illumination light emitted by the second light-transmitting plate 320 strikes the second light-transmitting plate 320, which then passes through the second light-transmitting plate 320 and strikes the wall. The mounting base 400 quickly transfers heat generated by the second light source board 310 to the housing 100, dissipating the heat to the external environment and effectively reducing the heat generated by the second light source board 310. Furthermore, the heat sink 120 accelerates heat transfer from the mounting base 400 to the housing 100, further accelerating heat dissipation from the first light source board 210.

[0042] In a specific embodiment, the mounting base 400 includes a mounting base plate 410 and a side plate 420, wherein the mounting base plate 410 is fitted and connected to the upper end portion of the heat sink 120, and the second light source panel 310 is fitted and arranged on the side of the mounting base plate 410 close to the second light outlet 113. Two side plates 420 are provided but not limited to only two, and the two side plates 420 are connected to the side of the mounting base plate 410 away from the second light outlet 113 and are arranged opposite to each other. A power supply 500 cavity 430 is defined between the mounting base plate 410 and the two side plates 420, and the power supply 500 of the wall lamp is assembled and connected to the power supply 500 cavity 430. It can be understood that the mounting base 400 is formed by connecting the mounting base plate 410 and the side plate 420. The overall structure of the mounting base 400 is simple and facilitates the installation of the second light source panel 310 and the power supply 500.

[0043] Furthermore, a portion of the heat sink 120 is threadedly connected with a fixing screw 450 for fixing the mounting base 400. Specifically, the heat sink 120 has a columnar connection portion 121 (see FIG. Figure 3 ), and a connection hole is axially defined in the connection portion 121. The mounting base 410 is fitted onto the end of the heat sink 120. A fastening screw 440 is provided through the mounting base 410. The fastening screw 440 is threadedly engaged with the connection hole of the connection portion 121, thereby securing the mounting base 400 to the heat sink 120.

[0044] Furthermore, the side panel 420 has mounting openings at both ends thereof for the power supply 500 cavity 430, allowing the power supply 500 to be installed within the power supply 500 cavity 430 through one of the mounting openings. Fastening screws 440 are provided at both ends of the side panel 420 near the mounting openings. The fastening screw 440 at one end of the side panel 420 abuts one end of the power supply 500, while the fastening screw 440 at the other end of the side panel 420 abuts the other end of the power supply 500. Thus, the power supply 500 remains installed within the power supply 500 cavity 430. It will be appreciated that the power supply 500 employs the above-described structural form, eliminating the need for corresponding structures on the power supply 500 to secure the power supply 500, thereby reducing the cost of the power supply 500 and making installation of the power supply 500 more convenient.

[0045] In some embodiments, reference Figure 2 and Figure 5A heat conducting plate 130 is also integrated into the inner side of the housing 100, and the end of the heat sink 120 away from the first light source assembly 200 is integrally connected to the heat conducting plate 130. The first light source assembly 200 includes a first light source board 210 and a polarizing lens 220, wherein the first light source board 210 is attached to the side of the heat conducting plate 130 away from the heat sink 120 and is disposed toward the first light outlet 112. The polarizing lens 220 is disposed on the side of the first light source board 210 close to the first light outlet 112, and is used to receive the illumination light from the first light source board 210 and direct the light obliquely forward.

[0046] In a specific application process, the first light source panel 210 emits illumination light toward the polarizing lens 220 , and the illumination light is refracted forward after passing through the polarizing lens 220 , so that the first light source panel 210 can illuminate the ground in front of the wall in a large area.

[0047] Furthermore, a heat conducting plate 130 is provided on the inner side of the housing 100, and the first light source board 210 is attached to the heat conducting plate 130. This arrangement allows the heat conducting plate 130 to quickly absorb heat emitted by the first light source board 210 and transfer it to the housing 100, thereby dissipating the heat to the external environment. The heat sink 120 accelerates the transfer of heat from the heat conducting plate 130 to the housing 100, thereby increasing the heat dissipation effect of the first light source board 210 and reducing the temperature of the first light source board 210.

[0048] Furthermore, the polarized lens 220 has an arc-shaped raised portion 221 and a block-shaped raised portion 222. The lamp beads of the first light source board 210 are arranged toward the arc-shaped raised portion 221, and the block-shaped raised portion 222 is arranged behind the arc-shaped raised portion 221. In use, the second light source board 310 projects illumination light behind the polarized lens 220. The arc-shaped raised portion 221 and the block-shaped raised portion 222 cooperate to refract the illumination light forward, thereby illuminating a large area of the ground in front of the wall.

[0049] In some embodiments, reference Figure 2 and Figure 5 The first light source assembly 200 is equipped with a reflector 230, which is disposed on the side of the polarizing lens 220 away from the first light source panel 210, and the second light source assembly 300 is not equipped with a reflector 230. It is understandable that the first light source assembly 200, through the provision of the reflector 230, can receive the light emitted by the first light source panel 210 and reflect it, so that the second light source panel 310 can illuminate the ground in front of the wall in a large area; conversely, the second light source assembly 300 is not equipped with a reflector 230, and the second light source panel 310 focuses the illumination upward, thereby better illuminating the wall and increasing the atmosphere of the light.

[0050] In other embodiments, the first light source assembly 200 and the second light source assembly 300 are both equipped with reflectors, and the first light source assembly 200 and the second light source assembly 300 can illuminate the front side of the wall in a large range, thereby increasing the atmosphere of top-down lighting.

[0051] Furthermore, the inner wall of the reflector 230 is provided with a first reflective slope 231 and a second reflective slope 232 at opposite sides, respectively. The first reflective slope 231 is arranged closer to the wall relative to the second reflective slope 232, that is, the first reflective slope 231 is the rear side surface of the inner wall of the reflector 230, and the second reflective slope 232 is the front side surface of the inner wall of the reflector 230, and the downward inclination angle of the first reflective slope 231 is greater than the downward inclination angle of the second reflective slope 232.

[0052] As will be appreciated, the first reflective bevel 231 is tilted downward at a steep angle, reflecting the received illumination light in a forward-facing direction. This ensures that the illumination light propagates forward at an angle, illuminating the ground over a wide area. Simultaneously, the second reflective bevel 232 is tilted downward at a shallower angle, minimizing interference with deflected light, thereby ensuring that the illumination light propagates forward at an angle. Furthermore, the second reflective bevel 232 reflects the received illumination light in a generally vertically downward direction, thereby enhancing the lighting effect on the ground.

[0053] In some embodiments, reference Figure 2 and Figure 5 The first light source assembly 200 further includes a first light-transmitting plate 240 and an anti-glare cover 250. The inner wall of the housing 100 has a stepped surface 111. The first light-transmitting plate 240 can be an anti-glare plate. The first light-transmitting plate 240 is disposed on the side of the reflector 230 away from the polarizing lens 220, with the edge of the first light-transmitting plate 240 abutting against the stepped surface 111. The anti-glare cover 250 is also disposed on the side of the first light-transmitting plate 240 away from the reflector 230. The anti-glare cover 250 is snap-connected to the inner wall of the housing 100, with the inner edge of the anti-glare cover 250 abutting against the edge of the first light-transmitting plate 240 away from the stepped surface 111. Thus, the anti-glare cover 250 is used to keep the first light-transmitting plate 240 abutting against the stepped surface 111, thereby securing the first light-transmitting plate 240 within the housing 100. In addition, the anti-glare cover 250 has an anti-glare effect on the light emitted by the first light source panel 210 and also plays a decorative role.

[0054] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
