[0002] With the improvement of living standards, people's demand for lighting in different scenarios is also getting higher and higher. Among them, some lamps that can change the color of light are widely used in various places.

[0003] Currently, most lamps of this type on the market use direct-down surface light sources, which often require densely distributed lamp beads on the chassis of the lamp, resulting in high production costs and thicker lamp bodies.

DETAILED DESCRIPTION

[0034] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] It should be noted here that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the solutions of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0036] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0037] See also Figures 1 to 4 As shown, a lamp 100 according to a preferred embodiment of the present invention includes a chassis 110, a frame 120 and a light control member 130. The frame 120 surrounds the chassis 110 and extends downward from the chassis 110. The light control member 130 is located at the end of the frame 120 away from the chassis 110. The chassis 110, the frame 120 and the light control member 130 together form an air cavity 150. A light source module 140 is installed inside the frame 120. The light source module 140 includes a light emitting module 141 and a light distribution member 142. Block 141 is configured to emit light, and the light distribution component 142 is configured to make the light emitted by the light-emitting module 141 be emitted toward the chassis 110 and the light control component 130. A reflective structure 111 is provided on the side of the chassis 110 facing the light control component 130. The function of the reflective structure 111 is to reflect the light emitted by the light source module 140 into the air cavity 150. Part of the light emitted by the light source module 140 to the light control component 130 will be reflected and then emitted into the air cavity 150, and part will be refracted by the light control component 130 and then emitted outward.

[0038] Through the provided light control member 130, part of the light incident on the light control member 130 is reflected back into the air cavity 150. After multiple reflections by the side wall 1424 and the chassis 110, the light finally emitted outward through the light control member 130 is mixed more evenly, and a better uniform light effect can be obtained. At the same time, the lamp 100 of the present invention adopts a side-emitting method, and the light source module 140 is installed on the inner side of the frame 120. The light distribution member 142 is used to control the emission angle of the light emitted by the light-emitting module 141. Compared with the direct-down light source, the use of the aluminum substrate is reduced, and the thickness of the lamp 100 is reduced, making the appearance of the lamp 100 lighter and more beautiful. At the same time, the side-emitting method also saves the number of light-emitting units 1411 in the light-emitting module 141, effectively reducing the manufacturing cost.

[0039] In this embodiment, the light-emitting module 141 includes a substrate 1412 and a plurality of light-emitting units 1411. The light-emitting units 1411 are arranged in a circular pattern on the substrate 1412. The substrate 1412 is fixedly connected to the inner side of the frame 120. The light-emitting units 1411 are covered by a light distribution member 142. The light distribution member 142 is configured to distribute the light emitted by the light-emitting units 1411 and control the ratio of light emitted to the chassis 110 and light emitted to the light control member 130. The light-emitting units 1411 are arranged in a circular pattern on the substrate 1412. A good light output effect can be achieved by simply arranging the light-emitting units 1411 in a single row and utilizing the reflection of light from the chassis 110 and the light control member 130.

[0040] The light-emitting module 141 includes at least two light-emitting units 1411 of different colors, which are arranged in a circular pattern on the substrate 1412. The light emitted by the light-emitting units 1411 of different colors is reflected multiple times by the chassis 110 and the light control member 130, resulting in more uniform light mixing. Furthermore, the light emitted by the light-emitting units 1411 of different colors can exhibit a wider range of color variations after mixing, thus enhancing the lighting quality of the lamp 100.

[0041] In this embodiment, the light-emitting module 141 includes light-emitting units 1411 in four colors: white, red, green, and blue. The light emitted by these four colors of light-emitting units 1411 can be mixed to produce a variety of different colors, thereby providing a better lighting effect. In other embodiments, light-emitting units 1411 of other colors may also be included, and the present invention is not limited thereto.

[0042] See also Figure 5 As shown, the light incident cavity 1421 includes a first incident surface 1422 facing the light emitting unit 1411, and a second incident surface 1423 connected to the first incident surface 1422, the light emitting surface 1425 includes a first incident surface 1426 close to the chassis 110, a second incident surface 1428 close to the light control member 130, and a third incident surface 1427 located between the first incident surface 1426 and the second incident surface 1428, the third incident surface 1427 protrudes in a direction away from the light emitting unit 1411, and the light distribution member 142 also includes a side wall 1424 extending from one end of the light incident cavity 1421 toward the light emitting unit 1411 to the light emitting surface 1425, and the side wall 1424 is configured to reflect light incident from the second incident surface 1423.

[0043] Part of the light emitted by the light-emitting unit 1411 is refracted by the second incident surface 1423 and then enters the light distribution component 142. After being reflected from the inner side of the side wall 1424, it is emitted toward the first exit surface 1426 and the second exit surface 1428. After being refracted by the first exit surface 1426, it is emitted toward the chassis 110. After being refracted by the second exit surface 1428, it is emitted toward the light control component 130 and the chassis 110. Part of the light emitted by the light-emitting unit 1411 enters the light distribution component 142 through the first incident surface 1422, and after being refracted by the second exit surface 1428, it is emitted toward the chassis 110 and the light control component 130.

[0044] See also Figure 6 As shown, in some embodiments, the light distribution member 142 is an eccentric structure, and the first incident surface 1422 of the light distribution member 142 is divided into a first portion close to the chassis 110 and a second portion relatively far from the chassis 110. The light emitting unit 1411 includes a center line perpendicular to the frame ( Figure 6 The distance between the center line and the first end 1432 is greater than the distance between the center line and the second end 1442. Thus, approximately 60% of the light emitted by the light-emitting unit 1411 enters the light distribution component 142 from the first portion, and approximately 40% enters the light distribution component 142 from the second portion. Furthermore, the first incident surface 1422 of the light distribution component 142 is tilted relative to the light-emitting unit 1411. Furthermore, the first incident surface 1422 is tilted relative to the light-emitting unit 1411, with the first end 1432 deviating toward the light-emitting unit 1411 and the second end 1442 deviating away from the light-emitting unit 1411. When the light emitted by the light-emitting unit 1411 is refracted at the first incident surface 1422, a larger proportion of the light will be emitted toward the chassis 110, thereby increasing the number of reflections of the light and the optical path of the light, so as to fully mix the light emitted by the light-emitting units 1411 of different colors, and finally the brightness uniformity of the light output is better.

[0045] In some other embodiments, the first incident surface 1422 may also be arranged parallel to the light-emitting unit 1411. In this case, among the light emitted through the light-emitting surface 1425 of the light distribution component 142, the proportion of the light emitted toward the chassis 110 to the light emitted by the light-emitting unit 1411 is still greater than the proportion of the light emitted toward the light control component 130 to the light emitted by the light-emitting unit 1411. The present invention does not impose any restrictions on this.

[0046] In some embodiments, a serrated surface 1429 is provided on the second exit surface 1428. The serrated surface 1429 can further deflect the light emitted from the second exit surface 1428 toward the chassis 110, so that more light will first be emitted to the chassis 110, and then reflected by the chassis 110 into the air cavity 150, thereby increasing the number of reflections of the light and thereby improving the light mixing effect.

[0047] In this embodiment, when the light distribution component 142 is an eccentric structure, when the light emitted by the light-emitting unit 1411 is emitted after passing through the light distribution component 142, the light emitted toward the chassis 110 accounts for a first proportion of the light emitted by the light-emitting unit 1411, and the light emitted toward the light control component 130 accounts for a second proportion of the light emitted by the light-emitting unit 1411. The first proportion is greater than the second proportion. Specifically, the first proportion is between 60% and 85%, and the second proportion is between 15% and 40%, that is, most of the light will be emitted toward the chassis 110 to increase the number of reflections of the light, and the light output brightness on the surface of the light control component 130 is more uniform, and its surface uniformity can reach 75%-90%.

[0048] In some embodiments, when the light distribution component 142 is a symmetrical structure, the first incident surface 1422 includes a first end 1432 close to the chassis 110, and a second end 1442 away from the chassis 110 relative to the first end 1432. The light-emitting unit 1411 has a center line perpendicular to the frame 120, and the distance between the center line and the first end 1432 is equal to the distance between the center line and the second end 1442. The light emitted by the light-emitting unit 1411 passes through the light distribution component 142 and is emitted in equal proportions toward the chassis 110 and the light control component 130.

[0049] See also Figure 7 As shown, this is a light intensity output curve of the light emitted by the light-emitting unit 1411 in one embodiment of the present invention when it is emitted after passing through the light-distributing component 142, wherein the blue line is the light intensity output curve emitted after passing through the light-distributing component 142 with a symmetrical structure, and the green line is the light intensity output curve emitted after passing through the light-distributing component 142 with an eccentric structure.

[0050] In this embodiment, the light distribution member 142 is an annular lens. A single light distribution member 142 can cover all light-emitting units 1411. The light distribution member 142 is made of one of PMMA, PC, and silicone. Light distribution members 142 made of these materials can be manufactured using processes such as extrusion and hot bending, allowing them to adapt to the shape of the frame while also providing good light transmittance and low manufacturing costs. In other embodiments, the light distribution member 142 can also be made of other materials, which are not limited by the present invention.

[0051] The distance between the light source module 140 and the chassis 110 is a first distance, and the distance between the light source module 140 and the light control member 130 is a second distance. The ratio of the first distance to the second distance is greater than or equal to 0.5 and less than or equal to 1. The distance between the light source module 140 and the chassis 110 is less than the distance between the light source module 140 and the light control member 130, so that the light emitted by the light source module 140 has a longer optical path after being reflected by the chassis 110, which can achieve better light mixing and make the final light output brightness more uniform.

[0052] See also Figure 8 and Figure 9 As shown, in this embodiment, the chassis 110 is provided with a continuously arranged reflective structure 111. The reflective structure 111 is arranged in concentric circles from the center of the chassis 110 outward. Specifically, the sawtooth structure includes intersecting connecting surfaces 1111 and reflecting surfaces 1112. The angle between the connecting surfaces 1111 and the reflecting surfaces 1112 is greater than 90 degrees. The angle between the light entering the reflecting surfaces 1112 and the light emitted after being reflected by the reflecting surfaces 1112 is greater than 90 degrees. This ensures that the light reflected by the chassis 110 can enter the air cavity 150 at a large angle, increasing the optical path and further improving the light mixing effect.

[0053] The reflectivity of the light control element 130 is between 40% and 60%. When the reflectivity is within this range, the brightness and uniformity of the light on the surface of the light control element 130 are well balanced, providing a better visual experience. In this embodiment, the light control element 130 is a tensioned film. In other embodiments, it can also be made of other materials, and the present invention is not limited to this.

[0054] See also Figure 10 As shown, the light emitted by the light-emitting unit 1411 of the lamp 100 passes through the light distribution part 142 and is emitted toward the chassis 110 and the light control part 130 respectively. The light emitted to the chassis 110 will be reflected by the reflective structure 111 on the chassis 110 and then emitted toward the light control part 130. Part of the light emitted to the light control part 130 will be directly emitted outward through the light control part 130, and part of the light will be reflected by the light control part 130 and then emitted toward the air cavity 150 and emitted toward the chassis 110 or the frame 120. The light emitted to the frame 120 will also be reflected into the chassis 110 after being emitted by the frame 120. In this way, part of the light will be reflected multiple times between the chassis 110 and the light control part 130, and finally a bright surface with uniform brightness is formed on the side of the light control part 130 facing away from the chassis 110.

[0055] In some other embodiments, the reflective structure 111 on the chassis 110 is a white coating applied on the surface of the chassis 110 to diffusely reflect the light incident on the chassis 110 , which can also achieve a relatively good light mixing effect.

[0056] In some embodiments, a mirror reflective film is provided on the inner side of the frame 120. When the light reflected by the chassis 110 enters the air cavity 150, part of it is directly directed toward the light control component 130, and part of it is directed toward the frame 120. The reflective film on the inner side of the frame 120 can reflect this part of the light again to achieve sufficient light mixing.

[0057] In some embodiments, the light source module 140 further includes a bracket 1413. The bracket 1413 includes a connecting plate 1414 fixedly connected to the frame 120, and extension plates 1415 symmetrically arranged on both sides of the connecting plate 1414 and extending away from the frame 120. The connecting plate 1414 and the extension plates 1415 are arranged to form a mounting groove 1416. The mounting groove 1416 has an opening (not shown) on the side away from the connecting plate 1414. The light emitting module 141 is located in the mounting groove 1416. The light source substrate 1412 is arranged on the side of the connecting plate 1414 away from the frame 120. Light emitted by the light emitting unit 1411 passes through the light distribution member 142 and is emitted from the opening. The opening on one side of the mounting groove 1416 limits the angle of light emitted by the light distribution member 142, restricting the emission of stray light at large angles and ensuring good uniformity of light output from the final lamp 100. A limiting portion 1417 is further provided at the end of the extension plate 1415 away from the connecting plate 1414. The end of the light distribution component 142 away from the connecting plate 1414 abuts against the limiting portion 1417. The limiting portion 1417 can prevent the light distribution component 142 from moving in the horizontal direction, making the overall structure of the light source module 140 more stable.

[0058] To sum up, the lamp 100 of the present invention adopts a side-emitting method, and the light source module 140 is installed on the inner side of the frame 120. The light-emitting units 1411 of different colors in the light source module 140 emit light, and the light passes through the light distribution component 142 and is emitted toward the chassis 110 and the light control component 130. The light emitted to the chassis 110 will be reflected by the reflective structure 111 of the chassis 110, and part of the light emitted to the light control component 130 will be reflected, and part will be refracted by the light control component 130 and emitted outward. After multiple reflections between the chassis 110 and the light control component 130, the light finally forms a light-emitting surface 1425 with uniform brightness on the surface of the light control component 130. The lamp 100 only needs fewer light-emitting units 1411 to present a better light-emitting effect, which reduces the manufacturing cost, and the overall volume of the lamp 100 is smaller.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
