[0002] In many scenarios, such as stages and entertainment venues, ambient lighting is often used to create a specific lighting environment. However, in related technologies, lighting devices are typically designed to emit light uniformly, resulting in a monotonous brightness pattern on the surface of the lighting device, which is not conducive to creating a suitable lighting atmosphere. Utility Model Content
[0003] The main technical problem solved by the embodiments of this application is to provide a lighting device that can form halos of different brightness on the housing, which is beneficial for creating a lighting atmosphere.
[0004] To solve the above-mentioned technical problems, one technical solution adopted in this application embodiment is: providing a lighting device, including a housing, a light-emitting element, and a light-emitting module. The housing is provided with a receiving groove; the light-emitting element has a first end and a second end opposite to each other, and the light-emitting element is received in the receiving groove. The light-emitting element is provided with at least a plurality of first through holes and a plurality of second through holes. The plurality of first through holes are spaced apart, and the plurality of second through holes are spaced apart, and from the first end to the second end, the first through holes and the second through holes are spaced apart from each other; the light-emitting module is disposed on the light-emitting element, the minimum distance between each first through hole and the light-emitting module is S1, the minimum distance between each second through hole and the light-emitting module is S2, the sum of the areas of each first through hole is A1, the sum of the areas of each second through hole is A2, S1 and S2 are different, and A2 > A1; the light emitted by the light-emitting module can pass through the first through hole or the second through hole, and thus be emitted to the housing.
[0005] In some embodiments, the light-emitting component is provided with a plurality of third through holes, which are spaced apart; the minimum distance between each third through hole and the second end is S3, the sum of the areas of each third through hole is A3, and S1, S2, and S3 are different from each other, with A3 > A2; the light emitted by the light-emitting module can pass through one of the first through hole, the second through hole, and the third through hole, and thus be emitted into the housing.
[0006] In some embodiments, S1 < S2 < S3.
[0007] In some embodiments, the diameter of the second through hole is greater than the diameter of the first through hole; and / or, the diameter of the third through hole is greater than the diameter of the second through hole.
[0008] In some embodiments, the first through hole and the second through hole have the same diameter, the number of second through holes is greater than the number of first through holes, and the minimum distance between two adjacent second through holes is less than the distance between two adjacent first through holes.
[0009] In some embodiments, a plurality of first through holes are spaced apart circumferentially along the reflector; and / or, a plurality of second through holes are spaced apart circumferentially along the reflector; and / or, a plurality of third through holes are spaced apart circumferentially along the reflector.
[0010] In some embodiments, the lighting device includes a mounting bracket disposed in a receiving groove, with a first end connected to the mounting bracket. From the first end to the second end, the distance between the light-emitting element and the mounting bracket gradually increases, so that a light-mixing groove is formed between the mounting bracket and the light-emitting element, and the light-emitting module is received in the light-mixing groove.
[0011] In some embodiments, the surface of the light-emitting element facing the light-mixing groove has a reflective layer configured to diffusely reflect light; the surface of the mounting bracket exposed to the light-mixing groove is configured to diffusely reflect light.
[0012] In some embodiments, the lighting device includes a reflector that covers the opening of the light mixing groove.
[0013] In some embodiments, the mounting bracket includes a cylindrical portion and a connecting portion, one end of the connecting portion is connected to one end of the cylindrical portion, and the other end of the connecting portion is connected to the inner wall of the housing. The diameter of the connecting portion gradually increases from one end to the other end.
[0014] In some embodiments, the lighting device includes a light-transmitting cover that covers at least a portion of the housing.
[0015] The beneficial effects of this application embodiment are as follows: Unlike the prior art, in this application embodiment, each first through hole and each second through hole are spaced apart, and the minimum distance S1 between each first through hole and the light-emitting module and the minimum distance S2 between each second through hole and the light-emitting module are different. In addition, since the sum of the areas of each second through hole is greater than the sum of the areas of each first through hole, the sum of the number of light rays passing through all the second through holes is greater than the sum of the number of light rays passing through all the first through holes. As a result, when the light emitted by the light-emitting module shines on the housing, at least two illumination areas with different brightness can be formed on the housing, thereby creating a lighting effect with different brightness in different illumination areas, which is beneficial for creating a lighting atmosphere.

[0026] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0027] In many scenarios, such as stages and entertainment venues, ambient lighting is often used to create a specific lighting environment. However, in related technologies, lighting devices typically emit light uniformly, resulting in relatively even brightness across the illuminated area, which is not conducive to creating a suitable lighting atmosphere.
[0028] Please see Figure 1 and Figure 2 The lighting device 100 includes a housing 1, a light-emitting element 3, and a light-emitting module 4. The light-emitting element 3 is installed inside the housing 1, and the light-emitting module 4 is disposed on the light-emitting element 3. The light-emitting module 4 can be a flexible light strip equipped with LED beads or a rigid light panel equipped with LED beads, etc. Exemplarily, the light-emitting module 4 in this embodiment is a ring-shaped flexible light strip.
[0029] For housing 1 mentioned above, please refer to... Figure 3 and Figure 4 The housing 1 is milky white and translucent, and its outer wall forms the light-emitting surface of the lighting device 100. The housing 1 is provided with a receiving groove 11, in which the light-emitting element 3 and the light-emitting module 4 are both received. The light-emitting element 3 is located between the light-emitting module 4 and the light-emitting surface. The receiving groove 11 is a relatively enclosed space so that the housing 1 can protect the light-emitting element 3 and the light-emitting module 4 and other components inside it.
[0030] In some embodiments, please refer to Figure 2 and Figure 4 The housing 1 includes an upper shell 12 and a lower shell 13. One end of the upper shell 12 is fixed to the lower shell 13, and the upper shell 12 and the lower shell 13 together form the aforementioned receiving groove 11. In this embodiment, the housing 1 includes an upper shell 12 and a lower shell 13. When assembling the lighting device 100, the light-emitting element 3 and the light-emitting module 4 can be assembled to the lower shell 13 first, and then the upper shell 12 and the lower shell 13 can be fixed, which facilitates the assembly of the lighting device 100.
[0031] For the aforementioned light-emitting element 3, please refer to... Figure 4 and Figure 5The light-emitting element 3 has a first end 31 and a second end 32. The first end 31 of the light-emitting element 3 is connected to the outer wall of the mounting frame 2. The light-emitting module 4 is disposed near the second end 32 of the light-emitting element 3. The light-emitting element 3 is provided with a plurality of first through holes 33 and a plurality of second through holes 34. The plurality of first through holes 33 are spaced apart from the first end 31 to the second end 32. The plurality of second through holes 34 are spaced apart. The minimum distance between each first through hole 33 and the light-emitting module 4 is approximately equal, and is defined as S1. The minimum distance between each second through hole 34 and the light-emitting module 4 is approximately equal, and is defined as S2. S1 and S2 are different. The sum of the areas of each first through hole 33 is A1, and the sum of the areas of each second through hole 34 is A2, and A2 > A1. The light emitted by the light-emitting module 4 can pass through the first through-hole 33 or the second through-hole 34, and thus exit onto the outer wall of the housing. Since the minimum distance S1 between each first through-hole 33 and the light-emitting module 4 and the minimum distance S2 between each second through-hole 34 and the light-emitting module 4 are different, the light emitted by the light-emitting module 4 can illuminate at least two different illumination areas of the housing 1. The light emitted from each first through-hole 33 illuminates one of the illumination areas, and the light emitted from each second through-hole 34 illuminates the other illumination area. (Reference) Figure 6 , Figure 6 The straight lines with arrows represent the trajectories of some light rays. One illuminated area corresponds to area a of the housing 1, which is illuminated by light rays passing through each of the first through holes 33. The other illuminated area corresponds to area b of the housing 1, which is illuminated by light rays passing through each of the second through holes 34. Since A2 > A1, the sum of the number of light rays passing through all the second through holes 34 is greater than the sum of the number of light rays passing through all the first through holes 33. This makes the brightness of area b greater than that of area a, thus creating a lighting effect with two illuminated areas of different brightness on the outer wall of the housing 1, which is beneficial for creating a lighting atmosphere.
[0032] It should be noted that, in this application, the minimum distance between feature C and feature B refers to the distance of the straight-line path from the end of feature C that is closest to feature B to the end of feature B that is closest to feature C.
[0033] In some embodiments, the distance between any two adjacent first through holes 33 is equal, which helps to improve the uniformity of brightness in region a.
[0034] In some embodiments, the distance between any two adjacent second through holes 34 is equal, which helps to improve the uniformity of brightness in region b.
[0035] In some embodiments, please refer to Figure 4 and Figure 5 The light-emitting element 3 is provided with a plurality of third through holes 35, which are spaced apart. The minimum distance between each third through hole 35 and the light-emitting module 4 is approximately equal, and the minimum distance between each third through hole 35 and the light-emitting module 4 is defined as S3, and S1, S2, and S3 are all different. The sum of the areas of each third through hole 35 is A3, and A3 > A2. The light emitted by the light-emitting module 4 can pass through one of the first through hole 33, the second through hole 34, and the third through hole 35, and thus be emitted onto the housing 1, so that the housing 1 can form at least three illumination areas; in addition, refer to Figure 6 Region c is the area where light passing through each of the third through holes 35 illuminates the housing 1. Since A3 > A2, the sum of the number of light rays passing through each of the third through holes 35 is greater than the sum of the number of light rays passing through each of the second through holes 34. This allows for the creation of lighting effects in at least three different brightness areas on the outer wall of the housing 1, which is beneficial for creating a lighting atmosphere.
[0036] In some embodiments, please refer to Figure 4 and Figure 5 The light-emitting element 3 is roughly annular, with the first end 31 forming the edge of the inner ring and the second end 32 forming the edge of the outer ring. The aforementioned first through holes 33 are spaced apart along the circumferential direction of the light-emitting element 3, the aforementioned second through holes 34 are spaced apart along the circumferential direction of the light-emitting element 3, and the aforementioned third through holes 35 are spaced apart along the circumferential direction of the light-emitting element 3, thereby creating at least three annular illumination areas on the outer wall of the housing 1. (Refer to...) Figure 6 One annular illumination area corresponds to area a, and the other annular illumination area corresponds to area b. In other embodiments, the shape of the light-emitting element 3 is not limited to annular, but can also be plate-shaped. In this case, the light-emitting surface of the corresponding housing 1 is a plane, which is not limited in this application.
[0037] In some embodiments, the minimum distance S1 between each first through-hole 33 and the light-emitting module 4 and the minimum distance S2 between each second through-hole 34 and the light-emitting module 4 satisfy the condition: S1 < S2. It is well known that the closer the distance to the light-emitting module 4, the higher the brightness. In this application, by providing multiple first through-holes 33 and multiple second through-holes 34, and ensuring that the sum of the areas A2 of each second through-hole 34 is greater than the sum of the areas A1 of each second through-hole 34, even if S1 < S2, the sum of the number of light rays passing through each second through-hole 34 is greater than the sum of the number of light rays passing through each first through-hole 33. In other words, the farther the distance to the light-emitting module 4, the higher the brightness. Please refer to... Figure 6 In this case, region a is closer to the light-emitting module 4 than region b. This application enables the brightness of region b to be higher than that of region a.
[0038] In some embodiments, the minimum distance S3 between each third through hole 35 and the light-emitting module 4 and the minimum distance S2 between each second through hole 34 and the light-emitting module 4 satisfy the following condition: S2 < S3, that is, S1 < S2 < S3. In other words, the minimum distance between the first through hole 33, the second through hole 34 and the third through hole 35 and the light-emitting module 4 gradually increases, and the distance between the corresponding regions a, b and c and the light-emitting module 4 gradually increases. Therefore, three light rings with different brightness can be formed on the surface of the housing 1 from bottom to top, and the light ring corresponding to region c has the highest brightness, the light ring corresponding to region b has the second highest brightness, and the light ring corresponding to region a has the lowest brightness, thereby creating a lighting effect with brightness gradually decreasing from bottom to top.
[0039] It is understandable that the relationship between S1, S2, and S3 is not limited to S1 < S2 < S3, but can also be other relationships, such as S3 < S1 < S2. In this case, among the three rings of light with different brightness formed from bottom to top on the surface of the shell 1, the uppermost ring has the highest brightness, the lowermost ring has the second highest brightness, and the middle ring has the lowest brightness. Or, for example, S3 < S2 < S1. In this case, among the three rings of light with different brightness formed from bottom to top on the surface of the shell 1, the uppermost ring has the highest brightness, the middle ring has the second highest brightness, and the lowermost ring has the lowest brightness.
[0040] In some embodiments, the diameters of the first through holes 33 are approximately equal, the diameters of the second through holes 34 are approximately equal, and the diameter of the second through holes 34 is larger than the diameter of the first through holes 33. In this embodiment, by making the diameter of the third through hole 35 larger than the diameter of the second through hole 34, and the diameter of the second through hole 34 larger than the diameter of the first through hole 33, it is advantageous to make the sum of the areas A2 of the second through holes 34 greater than the sum of the areas A1 of the first through holes 33, thereby making the brightness of region b higher than that of region a; in addition, by making the diameter of the second through hole 34 larger than the diameter of the first through hole 33, the number of openings can be reduced while making A2 greater than A1, thereby simplifying the processing technology.
[0041] In some embodiments, the diameters of the third through holes 35 are approximately equal, and the diameter of the third through holes 35 is larger than the diameter of the second through holes 34. This arrangement is advantageous because the sum of the areas A3 of the third through holes 35 is greater than the sum of the areas A2 of the second through holes 34, thereby making the brightness of region c higher than that of region b. In addition, by making the diameter of the third through holes 35 larger than the diameter of the second through holes 34, the number of openings can be reduced while making A3 greater than A2, thereby simplifying the processing technology.
[0042] In some embodiments, please refer to Figure 7The first through hole 33, the second through hole 34 and the third through hole 35 have the same diameter, and the number of second through holes 34 is greater than the number of first through holes 33, and the number of third through holes 35 is greater than the number of second through holes 34, so that the sum of the areas A2 of each second through hole 34 is greater than the sum of the areas A1 of each first through hole 33, and the sum of the areas A3 of each third through hole 35 is greater than the sum of the areas A2 of each second through hole 34.
[0043] It is understood that in some embodiments, the light-emitting element 3 may also be provided with a plurality of fourth through holes 36, which are distributed at intervals along the circumference of the light-emitting element 3. The minimum distance between each fourth through hole 36 and the second end 32 is greater than the minimum distance between each third through hole 35 and the second end 32, and the sum of the areas of each fourth through hole 36 is greater than the sum of the areas of each third through hole 35. This arrangement can increase the number of light rings formed by the lighting device 100, which is beneficial for creating a lighting atmosphere.
[0044] In some embodiments, the lighting device 100 further includes a mounting bracket 2, which is housed within a receiving groove 11 of the housing 1, and one end of the mounting bracket 2 is fixed to the lower housing 13. The first end 31 of the light-emitting element 3 is connected to the mounting bracket 2, and the light-emitting element 3 surrounds the outer side wall of the mounting bracket 2, while the light-emitting module 4 surrounds the mounting bracket 2. From the first end 31 to the second end 32, the distance between the light-emitting element 3 and the mounting bracket 2 gradually increases, thereby forming a light-mixing groove 5 between the mounting bracket 2 and the light-emitting element 3. The light-emitting module 4 is housed within the light-mixing groove 5 so that the light emitted by the light-emitting module 4 can be mixed within the light-mixing groove 5, and then pass through the light-emitting element 3 through one of the first through hole 33, the second through hole 34, or the third through hole 35, and then be emitted onto the housing 1. In this embodiment, by providing a light mixing groove 5, the light is mixed before being emitted from the first through hole 33, the second through hole 34, or the third through hole 35. This helps to reduce the difference in the number of light rays emitted from each of the first through holes 33, thereby improving the uniformity of brightness in region a; and reduces the difference in the number of light rays emitted from each of the second through holes 34, thereby improving the uniformity of brightness in region b; and reduces the difference in the number of light rays emitted from each of the third through holes 35, thereby improving the uniformity of brightness in region c.
[0045] In some embodiments, please refer to Figure 4The surface of the light-emitting element 3 facing the light-mixing groove 5 has a reflective layer (not shown). The reflective layer is configured to diffusely reflect light and avoids the first through hole 33, the second through hole 34, and the third through hole 35, so that light can pass through the first through hole 33, the second through hole 34, and the third through hole 35. The outer wall of the mounting bracket 2 is configured to reflect light. With this configuration, the light emitted by the light-emitting module 4 can be reflected by the outer wall of the mounting bracket 2 and the reflective layer of the light-emitting element 3 in the light-mixing groove 5, and then mixed in the light-mixing groove 5. The light then passes through one of the first through hole 33, the second through hole 34, and the third through hole 35 and is emitted onto the housing 1, thereby forming a halo of light with different brightness. In this embodiment, the outer wall of the mounting frame 2 and the reflective layer are both configured to reflect light, reducing the risk of light emitted by the light-emitting module 4 entering the mounting frame 2. Even if the light emitted by the light-emitting module 4 does not directly illuminate any of the first through hole 33, the second through hole 34, or the third through hole 35, but illuminates the reflective layer, this part of the light can still be emitted from any of the above-mentioned through holes after one or more reflections, which helps to improve the utilization rate of light and thus improve the lighting display effect of the lighting device 100.
[0046] In some embodiments, the mounting bracket 2 includes a cylindrical portion 21 and a connecting portion 22. The cylindrical portion 21 is generally cylindrical, and the connecting portion 22 is generally flared. One end of the connecting portion 22 is connected to one end of the cylindrical portion 21, and the other end of the connecting portion 22 is connected to the inner wall of the housing 1. The diameter of the connecting portion 22 gradually increases from one end to the other end, and the light-emitting element 3 surrounds the outer wall of the cylindrical portion 21. In this embodiment, the outer wall of the connecting portion 22 can reflect light. The gradually increasing diameter of the connecting portion 22 from one end to the other end reduces the risk of light escaping directly from the bottom of the housing 1, which is beneficial for improving light utilization.
[0047] In some embodiments, please refer to Figure 4 The lighting device 100 includes a reflector 6, which is generally annular. The reflector 6 is fitted onto the mounting frame 2 and surrounds the mounting frame 2, covering the opening of the light mixing groove 5. The reflector 6 is used to reflect light, reducing the risk of light emitted by the light-emitting module 4 leaking from the opening of the light mixing groove 5, which helps to further improve the light utilization rate of the lighting device 100.
[0048] In some embodiments, the lighting device 100 includes a light-transmitting cover 7 that covers at least a portion of the housing 1. The light-transmitting cover 7 is used to protect the housing 1 and reduce the risk of the housing 1 being damaged by impact.
[0049] In this embodiment, the first through holes 33 and the second through holes 34 are spaced apart, and the minimum distance S1 between the first through holes 33 and the light-emitting module 4 and the minimum distance S2 between the second through holes 34 and the light-emitting module 4 are different. In addition, since the sum of the areas of the second through holes 34 is greater than the sum of the areas of the first through holes 33, the sum of the number of light rays passing through all the second through holes 34 is greater than the sum of the number of light rays passing through all the first through holes 33. As a result, when the light emitted by the light-emitting module 4 shines on the housing 1, at least two illumination areas with different brightness can be formed on the housing 1, thereby creating a lighting effect with different brightness in different illumination areas, which is beneficial for creating a lighting atmosphere.
[0050] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
