[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference Figure 1 and Figure 2A diffuse reflection chandelier in an embodiment of the utility model includes a lamp body 100 and an extension portion 104. The lamp body 100 is provided with a reflection cavity 101. The reflection cavity 101 has an opening 102. A reflection plate 103 is provided in the inner wall of the reflection cavity 101. The reflection surface of the reflection plate 103 is an arc surface. It can be understood that the inner wall of the reflection cavity 101 is an arc surface. The reflection plate 103 can be fixed to the inner wall of the reflection cavity 101 by bonding. The reflection plate 103 can reflect light and reflect the light in multiple directions, which is beneficial to increase the lighting range.

[0032] The extension part 104 is integrally formed on the lamp body 100 and is located on both sides of the reflective cavity 101. It can be understood that the lamp body 100 is made of aluminum profile and is integrally formed by stretching or extrusion. The extension part 104 is a part of the lamp body 100, which makes the lamp highly integrated and does not need to install a face cover, thereby simplifying the structure and beautifying the appearance.

[0033] Furthermore, a light source plate 105 is provided on one side of the extension portion 104 near the opening 102, and a diffusion plate 106 is provided between the light source plate 105 and the reflection cavity 101. It can be understood that the light source plate 105 has a plurality of LED lamp beads, and the light emitted by the lamp beads on the light source plate 105 first passes through the diffusion plate 106. Since the diffusion plate 106 can change the propagation direction of the light and realize light scattering, the light distribution is more uniform and soft, so that the light irradiated into the reflection cavity 101 can be softer and more uniform, and the anti-glare effect is improved. In addition, since the reflection surface of the reflection plate 103 is an arc surface, the light can be reflected to multiple angles (refer to Figure 3 N in the image), thereby further avoiding excessive light concentration, increasing the lighting range, reducing glare, and improving the user experience.

[0034] Furthermore, the light source board 105 emits light toward the reflective plate 103 in an open direction away from the opening 102. Therefore, when the light is turned off, the human eye cannot directly observe the light source board 105 and its lamp beads, which is beneficial to improving the aesthetics of the lamp. When illuminated, the light emitted by the light source board 105 does not directly illuminate the naked eye and the light is relatively soft, achieving the effect of reducing glare.

[0035] Furthermore, the two light source boards 105 are symmetrically arranged on both sides of the extension part 104, which can simplify the structure of the lamp body 100, reduce the asymmetric structure on the lamp body 100, and help reduce the manufacturing cost. In addition, the light source board 105 is inclined with respect to the horizontal plane, so that along the width direction of the lamp body 100, the light source board 105 can occupy a smaller area of ​​the lamp body 100, that is, the width of the extension part 104 can be reduced, so that the width of the opening 102 is increased in the lamp body 100 of a certain size, which is conducive to improving the light passing efficiency and achieving a good lighting effect.

[0036] In other embodiments, one extension portion 104 may be provided, and the extension portion 104 is located on any side of the lamp body 100 along the width direction, which can also achieve the above-mentioned effects of increasing the lighting range and reducing glare.

[0037] Reference Figure 3 The extension part 104 is provided with a first mounting groove 107 and a second mounting groove 108, the diffuser plate 106 is inserted into the first mounting groove 107, and the light source board 105 is inserted into the second mounting groove 108, so that the diffuser plate 106 and the light source board 105 are easy to install. At the same time, the extension part 104 is provided with a third mounting groove 109 at one end close to the reflection cavity 101, and the two ends of the reflection plate 103 are abutted against the inner wall of the third mounting groove 109, which is conducive to conveniently fixing the reflection plate 103 during installation. It can be understood that the reflective cavity 101, the first mounting groove 107, the second mounting groove 108 and the third mounting groove 109 all penetrate the lamp body 100 along the length direction of the lamp body 100. The reflective cavity 101, the first mounting groove 107, the second mounting groove 108 and the third mounting groove 109 are simultaneously formed in the lamp body 100 during the molding process. During actual installation, the reflective plate 103, the light source plate 105 and the diffuser plate 106 can be inserted and installed from either end of the lamp body 100, which is easy to operate and helps to improve production efficiency.

[0038] Furthermore, the first mounting groove 107 and the second mounting groove 108 are arranged at intervals, so that there is a light guide channel 110 between the light source plate 105 and the diffuser plate 106. It can be understood that since the light emitted by the LED lamp beads is divergent, there is a hollow light guide channel 110 between the light source plate 105 and the diffuser plate 106, which is conducive to the light irradiation on the surface of the diffuser plate 106, so that the diffuser plate 106 can be fully utilized to scatter the light and achieve an anti-glare effect. Furthermore, the light source plate 105 and the diffuser plate 106 are arranged parallel to each other, which is conducive to the light irradiation on the surface of the diffuser plate 106, thereby facilitating the full utilization of the light.

[0039] Further, along the thickness direction of the diffuser plate 106, the first mounting groove 107 is provided with a supporting portion 111 and a first limiting portion 112, the supporting portion 111 is located between the first mounting groove 107 and the second mounting groove 108, and the first limiting portion 112 is located at one end of the extension portion 104 close to the opening 102. It can be understood that the supporting portion 111 is located on the side of the first mounting groove 107 away from the reflective cavity 101, and since the diffuser plate 106 and the light source board 105 are both inclined, the supporting portion 111 is used to effectively support the diffuser plate 106. The first limiting portion 112 is located on the other side of the first mounting groove 107 opposite to the supporting portion 111, and is used to prevent the diffuser plate 106 from being separated from the first mounting groove 107. Further, two first limiting portions 112 are provided, and the two first limiting portions 112 are located on both sides of the width of the first mounting groove 107, which can further increase the installation stability of the diffuser plate 106.

[0040] Furthermore, the third mounting groove 109 is further provided with a second limiting portion 113, and the second limiting portion 113 is located at a side of the third mounting groove 109 away from the inner wall of the reflection cavity 101. It can be understood that the second limiting portion 113 protrudes from one side of the third mounting groove 109, which can prevent the reflection plate 103 from being separated from the third mounting groove 109, and is conducive to providing good positioning when installing the reflection plate 103, so as to improve the convenience of installation.

[0041] Reference Figure 4 , the lamp body 100 is also provided with an end cover 115, and the end cover 115 covers both ends of the lamp body 100 along its length direction. Further, the extension portion 104 has a positioning hole 114, and the positioning hole 114 is located on the side of the extension portion 104 away from the reflective cavity 101, and the positioning hole 114 runs through the lamp body 100 along the length direction of the lamp body 100, that is, the positioning hole 114 can be formed simultaneously during the molding process of the lamp body 100, which is conducive to simplifying the process and reducing the use of materials, and is conducive to lightweighting and reducing material costs. At the same time, the end cover 115 is provided with a positioning portion 116, and the positioning portion 116 is located on the inner side of the end cover 115. There are two positioning portions 116, and the positioning portion 116 can be inserted into the positioning hole 114 to achieve the positioning of the end cover 115. Further, a fixing portion 117 is also provided on the inner side of the end cover 115, and the fixing portion 117 is located on the other side of the end cover 115 opposite to the positioning portion 116, refer to Figure 5 The end cap 115 covers the lamp body 100, the fixing part 117 is inserted into the lamp body 100, and the outer wall of the fixing part 117 abuts against the inner wall of the lamp body 100. The lamp body 100 and the fixing part 117 can be fixed by bolts, so that the end cap 115 and the lamp body 100 are stably connected. In addition, since the fixing part 117 is located on the side away from the extension part 104, the bolts screwed on the lamp body 100 are facing away from the direction of light illumination, so that the bolts of the lamp body 100 cannot be observed by human eyes, which is conducive to optimizing the appearance of the lamp body 100.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
