[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] The lighting fixtures provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0026] like Figures 1 to 11As shown in the illustration, this application provides a lighting fixture, which can be a chandelier. The fixture includes a first light-emitting module 100, a second light-emitting module 200, a sleeve 500, and a bracket 600. The sleeve 500 has a first light-emitting port 510 and a second light-emitting port 520 arranged opposite to each other. Both the first light-emitting module 100 and the second light-emitting module 200 are disposed within the sleeve 500. The first end of the bracket 600 extends through the second light-emitting port 520 into the sleeve 500 and is connected to the first light-emitting module 100 and the second light-emitting module 200. Optionally, the second end of the bracket 600 can be mounted on a ceiling, parapet, or other mounting base to allow the lighting fixture to hang. Optionally, the opposite end faces of the sleeve 500 and the bracket 600 can be horizontal, curved, or concave / convex, etc., without specific limitations. The first light-emitting module 100 faces the first light-emitting port 510. The light emitted by the first light-emitting module 100 passes through the first light-emitting port 510 and shines outside the sleeve 500 to form a first light spot. Optionally, the shape of the first light spot can be formed by setting different shapes of the first light-emitting ports 510 to meet the usage requirements. Optionally, the shape of the first light-emitting port 510 can be circular, triangular, rhomboid, etc., without specific limitations. Optionally, a light-transmitting structure can be provided at the first light-emitting port 510 to prevent moisture, dust, etc. from entering the sleeve 500. The second light-emitting module 200 faces the second light-emitting port 520. There is a light-transmitting gap between the second light-emitting port 520 and the bracket 600. The propagation direction of the light emitted by the second light-emitting module 200 is opposite to the propagation direction of the light emitted by the first light-emitting module 100. The light emitted by the second light-emitting module 200 shines out through the light-transmitting gap to form a second light spot. The sleeve 500 can move relative to the bracket 600 to adjust the distance between the first light outlet 510 and the first light-emitting module 100 and the width of the light transmission gap, thereby changing the size of the first light spot and the second light spot to meet different user lighting needs. It should be noted that the movement of the sleeve 500 relative to the bracket 600 can be achieved by manual drive by the user, or by drive components; this embodiment does not impose specific limitations.

[0027] It should be noted that in the above embodiments, the first light-emitting module 100 can also be fixed to the sleeve 500. The sleeve 500 and the first light-emitting module 100 can move relative to the bracket 600 at the same time. In this case, only the width of the light-transmitting gap is adjusted to change the size of the second light spot, while the size of the first light spot remains unchanged.

[0028] The light emitted by the second light-emitting module 200 can be reflected beyond the light-transmitting gap by the bracket 600, but the bracket 600 has a low reflectivity. Therefore, in an optional embodiment, the bracket 600 includes a frame 610 and a first light-distributing element 620. The first end of the first light-distributing element 620 extends through the second light-emitting port 520 into the sleeve 500. The first light-distributing element 620 has a reflective surface 621, at least a portion of which faces the light-transmitting gap, and the second light-emitting module 200 faces the reflective surface 621, thereby reflecting more of the light emitted by the second light-emitting module 200 beyond the light-transmitting gap to improve the light utilization rate of the second light-emitting module 200. The second end of the first light-distributing element 620 is connected to the frame 610.

[0029] Optionally, the first end of the first light distribution component 620 is provided with a threaded section, and the first light-emitting module 100 and the second light-emitting module 200 are both threadedly engaged with the threaded section. Alternatively, the threaded section can be coated with a fixing adhesive, so that the first light-emitting module 100 and the second light-emitting module 200 are both fixedly sleeved on the threaded section.

[0030] Either of the two embodiments described above can be selected. Alternatively, when using the lamp, the user can flexibly choose whether the first light-emitting module 100 and the second light-emitting module 200 are fixedly connected to the threaded section. When both the first light-emitting module 100 and the second light-emitting module 200 are fixedly connected to the threaded section, rotating the sleeve 500 can simultaneously change the size of the first light spot and the size of the second light spot. When neither the first light-emitting module 100 nor the second light-emitting module 200 are fixedly connected to the threaded section, rotating the sleeve 500 only changes the size of the second light spot. This provides the user with more usage modes, thereby meeting more of the user's lighting needs.

[0031] Optionally, the first end of the first light distribution element 620 is provided with a threaded section, and the second light-emitting module 200 is threadedly engaged with the threaded section. At this time, the second light-emitting module 200 can move relative to the first light distribution element 620, and the first light-emitting module 100 can be fixedly connected to the second light-emitting module 200. By driving the sleeve 500 to move, the first light-emitting module 100 and the second light-emitting module 200 can move simultaneously relative to the first light distribution element 620. At this time, the width of the light transmission gap can be adjusted, and the distance between the second light-emitting module 200 and the reflective surface 621 can also be adjusted, thereby quickly adjusting the size of the second light spot.

[0032] In another embodiment, the second light-emitting module 200 is fixedly sleeved on the threaded section. In this case, the second light-emitting module 200 has good stability, and when the sleeve 500 moves relative to the bracket 600, the width of the light-transmitting gap can be adjusted with a small driving force, which is convenient for user operation.

[0033] In a further optional embodiment, the first light-emitting module 100 includes a heat sink 110. The outer peripheral surface of the heat sink 110 is provided with threads. The pitch of the threads of the heat sink 110 is greater than the pitch of the threads in the threaded section. At this time, the sleeve 500 can change the width of the light-transmitting gap by rotating a small angle relative to the heat sink 110, thereby improving the adjustment efficiency.

[0034] In another embodiment, the end face of the heat sink 110 near the second light-emitting module 200 has a first threaded connection portion. The sleeve 500 is threadedly engaged with the first threaded connection portion. At this time, the size of the first threaded connection portion is small, and the thread size on it is small. The width or distance change caused by the user rotating the sleeve 500 is smaller. Therefore, the user can make precise adjustments according to the usage requirements to avoid the first light spot and the second light spot being too large or too small.

[0035] In another embodiment, the end face of the heat sink 110 near the second light-emitting module 200 has a telescopic part, and the sleeve 500 is connected to the telescopic part. The user can drive the telescopic part to deform by stretching the sleeve 500, so as to adjust the movement of the sleeve 500 relative to the bracket 600. This method is simpler to operate.

[0036] In another optional embodiment, the first light distribution element 620 includes a second threaded connection portion 622, a reflective portion 623, and a third threaded connection portion 624 connected in sequence. The first light-emitting module 100 and the second light-emitting module 200 are both sleeved on the third threaded connection portion 624 and threadedly engaged with it to increase the connection area between them, thereby improving connection reliability. The bracket 600 is threadedly engaged with the second threaded connection portion 622 to increase the connection area between them, thereby improving connection reliability. The reflective portion 623 has a reflective surface 621, which can be a stepped surface. This not only makes the first light distribution element 620 difficult to manufacture but also results in low reflectivity. Based on this, optionally, in the direction of extension of the third threaded connection 624 to the second threaded connection 622, the cross-sectional area of ​​the reflective part 623 gradually increases. At this time, the reflective part 623 has a conical structure, and the angle between the central axis of the first light distribution element 620 and the reflective surface 621 is an acute angle. This not only facilitates the manufacturing of the first light distribution element 620, but also has a high reflective efficiency, which is beneficial to improving the utilization rate of the light emitted by the second light-emitting module 200.

[0037] Alternatively, the reflective surface 621 is recessed in the direction away from the light-transmitting gap. In this case, the reflective surface has a light-focusing effect so that more of the light emitted by the second light-emitting module 200 is reflected, thereby further improving the utilization rate of the light emitted by the second light-emitting module 200.

[0038] In another optional embodiment, the first light-emitting module 100 includes a first light-emitting element 120, a heat sink 110, and a mounting plate 130. The heat sink 110 is threaded into the sleeve 500. In this case, the heat sink 110 is directly connected to the sleeve 500, eliminating the need for additional special connectors (such as adhesives, fasteners, etc.), thereby reducing the number of parts in the first light-emitting module 100 and facilitating user installation of the lamp. The first light-emitting element 120 can be positioned on the side of the mounting plate 130 away from the first light-emitting element 120. In this case, the distance between the first light-emitting element 120 and the heat sink 110 is relatively large, resulting in lower working efficiency of the heat sink 110. Optionally, the first light-emitting element 120 is disposed between the mounting plate 130 and the heat sink 110. In this case, the first light-emitting element 120 is closer to the heat sink 110 so that more of the heat generated by the first light-emitting element 120 during operation is absorbed by the heat sink 110, thereby protecting the first light-emitting element 120. The mounting plate 130 is provided with a first through hole 131 for light to pass through. The light source of the first light-emitting element 120 is disposed opposite to the first through hole 131. The first through hole 131 faces the first light outlet 510, that is, the light emitted by the first light-emitting element 120 passes through the first through hole 131 and the first light outlet 510 and shines outside the sleeve 500.

[0039] In addition, since the threaded section of the heat sink 110 is threadedly engaged with the sleeve 500, this connection method has a sealing effect. Therefore, when foreign objects such as dust and water vapor pass through the light-transmitting gap, they are first prevented from entering the inner cavity of the sleeve 500 by the threaded section of the heat sink 110 being threadedly engaged with the sleeve 500.

[0040] Optionally, the first light-emitting module 100 further includes a first fastener 150. The mounting plate 130 is provided with a second through hole, the first light-emitting element 120 is provided with a clearance hole, and the end face of the heat sink 110 is provided with a first threaded hole. One end of the first fastener 150 passes through the second through hole and the clearance hole in sequence and is threaded into the first threaded hole to improve the connection between the mounting plate 130 and the first light-emitting element 120 and the heat sink 110. Optionally, the number of second through holes is at least two, and each second through hole is spaced apart on both sides of the central axis of the mounting plate 130. The first fastener 150, the clearance hole, and the first threaded hole are provided in a one-to-one correspondence with the second through holes, thereby further improving the connection reliability between the mounting plate 130 and the first light-emitting element 120 and the heat sink 110.

[0041] In a further optional embodiment, the first light-emitting module 100 further includes a shock-absorbing member 140. Optionally, the shock-absorbing member 140 can be an O-ring, or other types of rubber rings, without specific limitations. The outer peripheral surface of the heat sink 110 is provided with a groove. Optionally, the groove is opened on the side of the threaded section of the heat sink 110 away from the second light-emitting module 200. The shock-absorbing member 140 is disposed in the groove and cooperates with the inner wall of the sleeve 500. When the sleeve 500 is adjusted, it will shake. The shock-absorbing member 140 can be used to absorb shocks to protect the first light-emitting module 100. In addition, the cooperation between the shock-absorbing member 140 and the inner wall of the sleeve 500 can also prevent dust from the external environment from entering the sleeve 500.

[0042] In another optional embodiment, the lamp further includes a second light distribution element 700 and a first light uniform element 800. Both the second light distribution element 700 and the first light uniform element 800 are disposed within the sleeve 500. The first light uniform element 800 is disposed between the second light distribution element 700 and the first light-emitting module 100. The second light distribution element 700 is disposed between the first light-emitting port 510 and the first light uniform element 800. That is, the light emitted by the first light-emitting module 100 is first diffused by the first light uniform element 800 to provide a uniform surface light source. Then, the light emitted by the surface light source is directed towards the second light distribution element 700 and is emitted after passing through the second light distribution element 700 and the first light-emitting port 510. Optionally, the second light distribution element 700 can be either a focusing lens or a defocusing lens. When the second light distribution element 700 is a focusing lens, it forms a smaller first light spot; when the second light distribution element 700 is a defocusing lens, it forms a larger first light spot. The choice can be made according to the actual lighting requirements, and no specific restrictions are imposed here.

[0043] Optionally, the sleeve 500 includes a lamp housing 530 and a decorative ring 540. The inner surface of the decorative ring 540 forms a first light outlet 510. The decorative ring 540 is disposed at the end of the lamp housing 530 opposite to the first light-emitting module 100. The decorative ring 540 is threaded into the lamp housing 530 and is located inside the lamp housing 530. This structure of the sleeve 500 improves the aesthetics of the luminaire. Optionally, the second light distribution element 700 and the first light-diffusing element 800 can be mounted on the decorative ring 540, making the structure of the luminaire more compact.

[0044] In an embodiment where the luminaire also includes a second light distribution element 700 and a first light uniform element 800, the inner wall of the decorative ring 540 can be stepped. The second light distribution element 700 and the first light uniform element 800 are both disposed on the inner wall of the decorative ring 540, and are respectively disposed on adjacent steps, so that the second light distribution element 700 and the first light uniform element 800 are spaced apart.

[0045] In another optional embodiment, the second light-emitting module 200 includes a second light-emitting element 210, a second light-diffusing element 220, and a spacer 230. The second light-emitting element 210, the spacer 230, and the second light-diffusing element 220 are sequentially sleeved on the first end of the first light-distributing element 620. The spacer 230 is disposed between the second light-emitting element 210 and the second light-diffusing element 220 to ensure that the light emitted by the second light-emitting element 210 travels a certain distance before entering the second light-diffusing element 220. The second light-diffusing element 220 is located between the second light-emitting element 210 and the reflective surface 621. After the light is diffused by the second light-diffusing element 220, a uniform surface light source is provided to illuminate more light onto the reflective surface 621, thereby improving the utilization rate of the light emitted by the second light-emitting element 210.

[0046] Optionally, the second light-emitting module 200 further includes a second light guide 240, which is sleeved on the first end of the first light distribution component 620. The second light guide 240 is located on the side of the second light homogenizer 220 near the reflective surface 621, and the light-emitting surface of the second light guide 240 faces the reflective surface 621. After passing through the second light homogenizer 220, the light enters the second light guide 240, which further diffuses the light. At this time, the second light guide 240 can be a defocusing lens, so that more light is reflected by the reflective surface 621 and then emitted through the light transmission gap.

[0047] Optionally, the second light-emitting module 200 further includes a second fastener 250, which is threadedly engaged with the threaded section of the first end of the first light-distributing component 620. The second fastener 250 is disposed on the side of the second light-emitting component 210 facing away from the reflective surface 621, and the side of the second fastener 250 facing the second light-emitting component 210 contacts the second light-emitting component 210. Optionally, the second fastener 250 can be a nut, or other types of fasteners; no specific limitation is made here.

[0048] Optionally, the frame 610 includes a main body 611, a sealing cover 612, and a first wire guide 613. The sealing cover 612 is located at the end of the main body 611 away from the second light-emitting module 200, and the sealing cover 612 is sealed to the main body 611. A second threaded hole is provided at the central axis of the sealing cover 612, and the first wire guide 613 is threaded to the second threaded hole. Optionally, the main body 611 can be a cylindrical structure, and the diameter of the cylindrical structure can be equal to the diameter of the sleeve 500, thereby improving the aesthetics of the lamp.

[0049] In an optional embodiment, the luminaire further includes a ceiling box module 300 and a suspension wire 400. Optionally, the suspension wire 400 can be a connecting wire with power transmission function. The ceiling box module 300 includes a ceiling box 310 and a power supply 320. Optionally, the ceiling box 310 can be a cylindrical structure. The power supply 320 is disposed inside the ceiling box 310. One end of the suspension wire 400 is electrically connected to the power supply 320, and the other end of the suspension wire 400 passes through the central hole of the bracket 600 and is electrically connected to the second light-emitting module 200 and the first light-emitting module 100 respectively, thereby supplying power to the first light-emitting module 100 and the second light-emitting module 200. Furthermore, the suspension wire 400 is positioned at the central axis of the entire luminaire to ensure uniform force distribution on the edge areas of the luminaire, thereby preventing the luminaire from tilting. Additionally, the suspension wire 400 passing through the central hole of the bracket 600 can improve the aesthetics of the luminaire.

[0050] In an embodiment where the bracket 600 includes a frame 610 and a first light distribution element 620, the central hole includes a first central hole and a second central hole. The first central hole is opened in the frame 610, and the second central hole is opened in the central axis of the first light distribution element 620. The central axis of the first clearance hole coincides with the central axis of the second clearance hole so that the suspension wire 400 can pass through.

[0051] Optionally, the ceiling box 310 includes an upper cover 311, a box body 312, a lower cover 313, and a second wire guide 314. The upper cover 311 and the lower cover 313 are threadedly engaged with the box body 312. A third threaded hole is provided at the central axis of the lower cover 313. The second wire guide 314 is threadedly engaged with the third threaded hole. The other end of the suspension wire 400 passes through the second wire guide 314.

[0052] Optionally, the upper and lower ends of the box body 312 are respectively provided with a third through hole and a fourth through hole. The ceiling box module 300 also includes a power bracket 330, at least two third fasteners 340, and at least two threaded connectors 350. The power supply 320 is disposed in the power bracket 330, which is disposed inside the ceiling box 310. The upper cover 311 is fixed to the ceiling by at least two threaded connectors 350 to ensure the sturdiness of the entire light fixture. After the upper cover 311 is threadedly engaged with the box body 312, one end of the third fastener 340 passes through the third through hole on the box body 312 and is threadedly engaged with the upper cover 311 to improve the connection sturdiness between the upper cover 311 and the box body 312. Similarly, after the lower cover 313 is threadedly engaged with the box body 312, one end of the third fastener 340 passes through the fourth through hole on the box body 312 and is threadedly engaged with the upper cover 311 to improve the connection sturdiness between the lower cover 313 and the box body 312.
