Description

Technical Field

[0002] Generally, a wall lamp capable of emitting light up and down includes: a mounting base assembly, a light source board disposed on the upper and lower sides of the mounting base assembly, and a lampshade mounted on the upper and lower sides of the mounting base assembly and covering the light source board. Because the lampshade has a relatively high height, if the lampshade is set as a single-layer transparent cover body, the brightness of the part of the lampshade close to the light source is relatively bright, and the brightness of the part of the lampshade far from the light source is less than that of the part of the lampshade close to the light source, resulting in uneven brightness of the light source in the lampshade, easy formation of light spots, and reduction of the user experience.

[0003] In order to make the emitted light evenly cover the entire interior of the lampshade and avoid the generation of light spots, the traditional lampshade is divided into two layers. The outer layer is a transparent lampshade, and the inner layer is a light-transmitting milky white lampshade. Among them, the milky white lampshade evenly guides the light and then passes through the transparent lampshade and emits it to the outside, so that the light emission of the wall lamp is uniform and there are no light spots. However, the above lampshade is a smooth two-layer structure, not only the shape of the lampshade is relatively single, but also the manufacturing cost of the lampshade is increased, which is not conducive to the popularization of the lampshade.

The refracted light of the multiple first refraction convex surfaces fills the space inside the transparent lampshade body. With the above scheme, the utility model can achieve the effect of the traditional double-layer lampshade by using a single-layer transparent lampshade body, overcoming the disadvantages of uneven light emission and easy formation of light spots of the traditional single-layer lampshade; by arranging multiple first refraction convex surfaces on the outer side surface of the single-layer transparent lampshade body, the disadvantages of the traditional double-layer lampshade, not only the shape of the lampshade is single, but also the manufacturing cost of the lampshade is increased, are overcome; on the basis of improving the use experience of the lampshade, the production cost of the lampshade is further reduced.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0026] In the description of the present utility model, the term "a plurality" refers to two or more, unless otherwise clearly defined. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0027] It should be noted that when an element is referred to as "assembled on", "mounted on", "fixed to" or "arranged on" another element, it can be directly connected to the other component or there may be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may also be an intermediate element.

[0028] Generally, the wall lamp that can emit light up and down includes: a mounting base assembly, a light source board disposed on the upper and lower sides of the mounting base assembly, and a lamp shade that is mounted on the upper and lower sides of the mounting base assembly and covers the light source board. Since the lamp shade has a relatively high height, if the lamp shade is set as a single-layer transparent cover body, the brightness of the part of the lamp shade close to the light source is relatively bright, and the brightness of the part of the lamp shade far from the light source is less than that of the part of the lamp shade close to the light source, resulting in uneven brightness of the light source in the lamp shade, easy formation of light spots, and reduction of the user experience.

[0029] In order to make the emitted light evenly cover the entire interior of the lamp shade and avoid the generation of light spots, the traditional lamp shade is divided into two layers. The outer layer is a transparent lamp shade, and the inner layer is a light-transmitting milky white lamp shade. Among them, the milky white lamp shade evenly exports the light and then passes through the transparent lamp shade and emits it to the outside, so that the light output of the wall lamp is uniform and there are no light spots; however, the above lamp shade is a smooth two-layer structure, not only the shape of the lamp shade is relatively single, but also the manufacturing cost of the lamp shade is increased, which is not conducive to the popularization of the lamp shade.

[0030] Such as Figure 1 、 Figure 2 and Figure 3 As shown, the embodiment of the present utility model provides a wall lamp, which includes: a mounting base assembly 10, an LED light source board 20, an LED driver 30, and a wall lamp lamp shade 40 with uniform light output. The LED driver 30 is mounted in the mounting base assembly 10. The LED light source board 20 is mounted on the upper and lower sides of the mounting base assembly 10 and is electrically connected to the LED driver 30. The wall lamp lamp shade 40 with uniform light output is mounted on the mounting base assembly 10 and covers the LED light source board 20. The light emitted by the LED light source board 20 passes through the wall lamp lamp shade 40 with uniform light output and emits to the outside. The mounting base assembly 10 is used to fix the wall lamp to positions such as walls.

[0031] Specifically, the wall lamp lamp shade 40 with uniform light output includes: a single-layer transparent lamp shade body 41 with a certain height. The transparent lamp shade body 41 has an opening. A plurality of first refraction convex surfaces 411 are formed by inward depression on the outer side surface of the transparent lamp shade body 41, and the plurality of first refraction convex surfaces 411 evenly cover the outer side surface of the transparent lamp shade body 41;

[0032] Among them, the multiple first refracting convex surfaces 411 include: a first refracting portion 4111 that refracts light toward the vicinity of the opening of the transparent lamp cover body 41 on one side near the opening of the transparent lamp cover body 41, a second refracting portion 4112 that refracts light toward the vicinity away from the opening of the transparent lamp cover body 41 on the side away from the opening of the transparent lamp cover body 41, and a third refracting portion 4113 that is located between the first refracting portion 4111 and the second refracting portion 4112 and refracts light toward a direction parallel to the opening of the transparent body lamp cover. The refracted light of the multiple first refracting convex surfaces 411 fills the space inside the transparent lamp cover body 41, avoiding excessive local brightness and the generation of light spots inside the transparent lamp cover body 41.

[0033] In the present utility model, by adopting the above scheme, the present utility model can achieve the effect of a traditional double-layer lamp cover with a single-layer transparent lamp cover body 41, overcoming the disadvantages of uneven light output and easy formation of light spots of a traditional single-layer lamp cover; by arranging multiple first refracting convex surfaces 411 on the outer side surface of the single-layer transparent lamp cover body 41, it overcomes the disadvantages of a traditional double-layer lamp cover, not only having a single lamp cover shape but also increasing the manufacturing cost of the lamp cover; on the basis of improving the use experience of the lamp cover, the production cost of the lamp cover is further reduced.

[0034] As Figure 4 、 Figure 5 and Figure 6 shown, in order to make the light output of the transparent lamp cover body 41 more uniform and avoid the appearance of light spots, the first refracting convex surface 411 is hemispherical. The hemispherical shape can increase the refracting area of each refracting portion of the first refracting convex surface 411 and improve the refracting effect. In the present utility model, the first refracting convex surface 411 can also be diamond-shaped. However, due to the existence of edges and corners in the diamond shape, the refracting area of each refracting portion of the first refracting convex surface 411 is reduced. Although a similar effect can be achieved, the effect is a bit worse than that of the hemispherical shape.

[0035] In order to avoid affecting the refracting efficiency of the first refracting convex surface 411, the inner side surface of the transparent lamp cover body 41 is smooth, avoiding the appearance of prism surfaces on the inner side of the transparent lamp cover body 41, thereby refracting light to other positions and affecting the refracting efficiency of the first refracting convex surface 411, and further making the light output of the transparent lamp cover body 41 uneven.

[0036] To further fill the inside of the transparent lamp cover body 41 with light, the top of the transparent lamp cover body 41 is plate-shaped, and a second refracting convex surface 412 extends inward from the inner side of the top of the transparent lamp cover body 41. The second refracting convex surface 412 is an irregular prism surface, and the second refracting convex surface 412 refracts part of the outgoing light into the transparent lamp cover body 41, thereby increasing the brightness of the light inside the transparent lamp cover body 41.

[0037] To facilitate the demolding of the transparent lamp cover body 41 during the injection molding process, the cross-sectional area of the transparent lamp cover body 41 gradually increases from the top to the opening of the transparent lamp cover body 41, so as to facilitate the injection molding demolding of the transparent lamp cover body 41.

[0038] To install the transparent lamp cover body 41, the installation base assembly 10 includes: a base body 11, and fixing grooves 111 are provided on both the upper and lower sides of the base body 11; a fixing convex edge 413 extends from the opening of the transparent lamp cover body 41 towards the fixing groove 111, and after the fixing convex edge 413 is embedded in the fixing groove 111, the fixing convex edge 413 is fixed to the fixing groove 111 with glue.

[0039] To supply power to the LED light source board 20, a receiving cavity 112 is provided inside the base body 11, and the LED driver 30 is received in the receiving cavity 112; threading holes 113 communicating the receiving cavity 112 and the outside are provided on both the upper and lower sides of the base body 11. After the LED light source board 20 is installed on both the upper and lower sides of the base body 11, the power cord led out by the LED driver 30 passes through the threading holes 113 and is electrically connected to the LED light source board 20.

[0040] To fix the wall lamp, the installation base assembly 10 further includes: a base fixing member 12, and the base fixing member 12 is embedded in the opening on one side of the base body 11; first fixing holes 114 are provided on both sides of the opening on one side of the base body 11, and second fixing holes 121 are provided on both sides of the base fixing member 12. The base fixing member 12 is fixed to the base body 11 after fixing screws sequentially pass through the corresponding first fixing holes 114 and the second fixing holes 121; a third fixing hole 122 is provided on the base fixing member 12, and a screw passes through the third fixing hole 122 and extends into the position where the wall lamp needs to be fixed for fixing.

[0041] To supply power to the LED driver 30, a wire inlet hole 123 communicating the receiving cavity 112 and the outside is provided on the base fixing member 12, and the connected power cord passes through the wire inlet hole 123 and extends into the receiving cavity 112 to be electrically connected to the LED driver 30.

[0042] The above has described the present utility model in detail in conjunction with the drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principles and spirit of the present invention, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
