Description

[0001] This application is a divisional application. The parent application has the application number 202310312501.2, the application date is March 27, 2023, and the invention title is "Lighting Fixture Assembly and Lighting Fixture". Technical Field

[0002] This invention relates to the field of lighting technology, and in particular to a lamp assembly and a lamp. Background Technology

[0003] A typical lighting fixture includes a housing, a light-emitting element, a reflector, and a light-transmitting element. The light-emitting element, reflector, and light-transmitting element are mounted on the housing, and the light emitted by the light-emitting element passes sequentially through the reflector and light-transmitting element. To adjust the light distribution direction, the entire lighting fixture is rotated and connected to a wall, for example, by pivoting both sides of the housing to the wall. This allows the light distribution direction to be adjusted by tilting the fixture. However, the lighting fixture can only rotate in one direction, making it difficult to flexibly adjust the light distribution direction.

[0004] Chinese patent No. 202011342945.3 discloses an adjustable light distribution optical module, including a first cylinder, a second cylinder, and a polarizing lens. The first and second cylinders are rotatably connected, and the polarizing lens is rotatably disposed within the inner cavity of the first cylinder. The polarizing lens has a guide positioning part along its vertical axis of rotation, and the second cylinder has an inclined guide slot. The guide positioning part and the guide slot are slidably connected. By rotating the first cylinder, the polarizing lens can rotate synchronously with the first cylinder in the horizontal plane. Simultaneously, due to the guiding effect of the guide positioning part on the polarizing lens and the guide slot on the second cylinder, the polarizing lens also flips at a certain angle relative to its axis of rotation in the vertical plane, achieving adjustment of the light distribution angle in the vertical plane. However, the horizontal and vertical adjustments of the polarizing lens are mutually restrictive, making it impossible to adjust the light distribution in the horizontal and vertical directions independently.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] See Figures 1 to 7 In one embodiment, a lamp assembly 10 includes a mounting member 100 and a light-transmitting member 200. The mounting member 100 is rotatably mounted on a lamp housing 20, and the light-transmitting member 200 is rotatably mounted on the mounting member 100. The rotation direction of the mounting member 100 is different from the rotation direction of the light-transmitting member 200. The mounting member 100 is rotatably mounted in a housing groove 20A of the lamp housing 20, and the light-transmitting member 200 is disposed in the housing groove 20A of the lamp housing 20. The light-transmitting member 200 is used to direct the light emitted by the light-emitting body 30 toward the reflector 300, so as to reflect the light out of the outside of the lamp housing 20 through the reflector 300.

[0038] The lamp housing 20 is mounted on a mounting wall, in contact with the wall. The mounting component 100 is isolated from the wall and can rotate within the housing 20, its rotation no longer restricted by the wall. The light-transmitting component 200 transmits light, directing it towards the reflector 300 or the exterior of the luminaire. The light-emitting element 30 can be mounted within the housing 20; by adjusting its position, its light is directed towards the light-transmitting component 200. The light-transmitting component 200 is mounted on the mounting component 100; rotating the mounting component 100 causes it to rotate in the same direction, thus adjusting the light distribution direction. The light-transmitting component 200 can rotate independently of the mounting component 100, and it can also rotate in a direction opposite to the rotation direction of the mounting component 100. This allows the light-transmitting element 200 to rotate in two directions, enabling independent adjustment of its position in each direction and thus regulating the light distribution in both the horizontal and vertical directions. Furthermore, since the rotation of the light-transmitting element 200 in both directions is independent, independent polarization adjustment in both the horizontal and vertical directions is possible. The light-transmitting element 200 and the mounting component 100 are relatively fixed together by static friction, effectively securing them in close contact.

[0039] This application assembles the light-transmitting element 200 and the mounting element 100, allowing the polarization direction to be adjusted via the light-transmitting body of the luminaire assembly 10, and the light distribution direction to be adjusted vertically and horizontally via the rotation of the luminaire assembly 10. This results in precise and clear light distribution, allowing for accurate positioning of the luminaire assembly 10 to precisely illuminate the target area, thus integrating the adjustment of the luminaire. Rotating the light-transmitting body enables switching between symmetrical and asymmetrical light spots, with a uniform transition during the switching process.

[0040] See Figure 1 Light distribution adjustment is achieved by rotating the light-transmitting element 200. Figure 1 The left side shows the illumination of the lamps under direct light. Figure 1 The right side shows the illumination of the lamp after the light-transmitting component 200 is rotated relative to the mounting component 100.

[0041] To ensure that the rotation direction of the mounting component 100 and the rotation direction of the light-transmitting component 200 relative to the mounting component 100 are different, see [reference needed]. Figures 7 to 9In some embodiments, the rotation axis of the mounting member 100 intersects with or is not in the same plane as the rotation axis of the light-transmitting member 200, so that the angle between the light and two different directions can be adjusted by rotating the mounting member and the light-transmitting member. When the rotation axis of the mounting member 100 intersects with the rotation axis of the light-transmitting member 200, the rotation axes of the mounting member 100 and the light-transmitting member 200 are located in the same plane, but the rotation directions of the mounting member 100 and the light-transmitting member 200 are different, enabling the light-transmitting member 200 to adjust the polarization in the horizontal and vertical directions. When the rotation axis of the mounting member 100 is not in the same plane as the rotation axis of the light-transmitting member 200, the rotation axes of the mounting member 100 and the light-transmitting member 200 are located in different planes, thus the rotation directions of the mounting member 100 and the light-transmitting member 200 are different.

[0042] For convenient adjustment of the light-transmitting element 200 in the horizontal and vertical directions, see [link / reference]. Figures 9 to 10 Furthermore, the rotation axis of the mounting component 100 is perpendicular or perpendicular to the rotation axis of the light-transmitting component 200. Since the rotation axis of the mounting component 100 is perpendicular or perpendicular to the rotation axis of the light-transmitting component 200, the mounting component 100 and the light-transmitting component 200 rotate independently in two directions. The component of the rotation axis of the mounting component 100 on the rotation axis of the light-transmitting component 200 is zero. When the rotation of the mounting component 100 drives the rotation of the light-transmitting component 200, the rotation component of the light-transmitting component 200 on its rotation axis is zero. Rotation of the light-transmitting component 200 in one direction does not change its position in the other direction. For convenient adjustment of the polarization direction, see [reference needed]. Figure 9 and Figure 10 Furthermore, the rotation axis of the mounting member 100 is parallel to the light-emitting direction of the light-emitting body 30, and the rotation axis of the light-transmitting member 200 is perpendicular to the light-emitting direction of the light-emitting body 30. To facilitate light illumination onto the reflector cup 300, in some embodiments, the rotation axis of the mounting member 100 coincides with the central axis of the reflector cup 300. Furthermore, the rotation axis of the light-transmitting member 200 is perpendicular to the central axis of the reflector cup 300. Furthermore, the rotation axis of the mounting member 100 coincides with the central axis of the lamp housing 20. Furthermore, the rotation axis of the light-transmitting member 200 is perpendicular to the central axis of the lamp housing 20.

[0043] In some embodiments, see Figure 2 , Figure 3 , Figure 4 and Figure 9 The rotation axis of the mounting component 100 is consistent with the light emission direction of the light-emitting body 30. That is to say, the rotation axis of the mounting component 100 can be parallel to the light emission direction of the light-emitting body 30; or, the rotation axis of the mounting component 100 can be approximately parallel to the light emission direction of the light-emitting body 30 (that is, the two may be set at a small angle, such as 1 degree, 2 degrees, 5 degrees or 10 degrees, etc.).

[0044] To rotate the mounting component 100 onto the lamp housing 20, see [reference needed]. Figure 9 and Figure 10 In some embodiments, a rotating part is provided on the outer periphery of the mounting member 100. The rotating part is rotatably connected to the lamp housing 20 so as to change the direction of the light by rotating the rotating part. In order to rotatably mount the mounting member 100 within the housing groove 20A of the lamp housing 20, in some embodiments, the rotating part is rotatably mounted within the housing groove 20A of the lamp housing 20.

[0045] To achieve a rotatable connection between the mounting component 100 and the lamp housing 20, see [reference needed]. Figure 9 and Figure 10 In some embodiments, the rotating part includes a mounting protrusion 110, which is slidably disposed within the lamp housing rotation groove 20B of the lamp housing 20; and / or, the rotating part includes a mounting rotation groove for sliding of the lamp housing protrusion of the lamp housing 20. The lamp housing rotation groove 20B is formed on the side wall of the housing groove 20A of the lamp housing 20, and the lamp housing protrusion is disposed on the side wall of the housing groove 20A of the lamp housing 20. The mounting protrusion 110 is disposed on the outer side wall of the mounting member 100, and the mounting rotation groove is formed on the outer side wall of the mounting member 100. To achieve 360-degree rotation of the mounting member 100, in some embodiments, the extension path of the lamp housing rotation groove 20B is circular, and the lamp housing rotation groove 20B is circumferentially formed on the side wall of the housing groove 20A of the lamp housing 20; the extension path of the mounting rotation groove is circular, and the mounting rotation groove is circumferentially formed on the outer side wall of the mounting member 100. To facilitate the installation of the mounting member 100 into the lamp housing 20, in some embodiments, at least two mounting protrusions 110 are provided, each mounting protrusion 110 being circumferentially disposed on the outer side wall of the mounting member 100. Further, the mounting protrusions 110 are evenly distributed on the outer side wall of the mounting member 100. To allow the mounting protrusions 110 to slide more smoothly within the lamp housing rotation groove 20B, in some embodiments, the mounting protrusions 110 are spherical or hemispherical.

[0046] For easy insertion of the mounting protrusion 110 into the lamp housing rotating slot 20B, see [reference needed]. Figure 2 and Figure 8In some embodiments, the sidewall of the mounting member 100 is provided with a press-fit hole 120, which is disposed along the outer periphery of the mounting protrusion 110. Since the outer periphery of the mounting protrusion 110 is provided with the press-fit hole 120, the mounting protrusion 110 can be pressed inwards and then inserted into the lamp housing 20, so that the mounting protrusion 110 is fitted into the lamp housing rotation groove 20B. Further, the press-fit hole 120 is disposed at least 180 degrees around the outer periphery of the mounting protrusion 110. Further, the press-fit hole 120 is disposed around three sides of the outer periphery of the mounting protrusion 110. Specifically, each mounting protrusion 110 is provided with a press-fit hole 120 around its outer periphery. To make pressing the mounting protrusion 110 easier, in some embodiments, the material of the mounting protrusion 110 includes plastic. Further, the material of the mounting member 100 includes plastic.

[0047] To prevent the light-transmitting element 200 from obstructing the inward pressing of the mounting protrusion 110, see [reference needed]. Figure 2 , Figure 6 and Figure 7 In some embodiments, the light-transmitting element 200 has a raised inner pressure hole 225, and the mounting protrusion 110 is movably inserted through the raised inner pressure hole 225.

[0048] To reduce the space occupied by the mounting component 100 and the light-transmitting component 200, see [reference needed]. Figure 7 and Figure 9 In some embodiments, the mounting member 100 is in the shape of a ring-shaped sleeve, and is fitted around the outer periphery of the light-transmitting member 200. Further, the mounting member 100 has a mounting groove 130 and a light-transmitting opening 140. The light-transmitting member 200 is rotatably disposed within the mounting groove 130, and the light-transmitting opening 140 allows light to pass through. The light emitted by the light-emitting element 30 shines onto the light-transmitting member 200, passes through the light-transmitting member 200, exits from the light-transmitting opening 140 of the mounting member 100, and then strikes the reflector 300.

[0049] To allow light to pass through the light-transmitting element 200 within the mounting slot 130, see... Figure 6 In some embodiments, the light-transmitting element 200 includes a light-transmitting portion 210 and a blocking portion 220 connected to each other. The blocking portion 220 is disposed on the outer periphery of the light-transmitting portion 210 and is rotatably connected to the mounting member 100. To further secure the connection between the light-transmitting element 200 and the mounting member 100, the blocking portion 220 is further disposed around the outer periphery of the light-transmitting portion 210, and the blocking portion 220 surrounds the light-transmitting element 200 at least once. To allow more light to pass through the light-transmitting portion 210, in some embodiments, the width of the light-transmitting opening 140 of the mounting member 100 is greater than or equal to the width of the light-transmitting portion 210. To reduce the space occupied by the mounting member 100 and the light-transmitting element 200, see [reference needed]. Figure 7 In some embodiments, the width of the mounting groove 130 is greater than the width of the light-transmitting element 200. Further, the width of the mounting groove 130 is greater than the width of the blocking portion 220.

[0050] To reduce the weight of the light-transmitting element 200, see [reference needed]. Figure 9 and Figure 10 In some embodiments, the blocking portion 220 is annular, and the width of the blocking portion 220 gradually increases from the side near the outer side of the lamp housing 20 to the side near the inner side of the lamp housing 20. The light-transmitting portion 210 is located within the ring of the blocking portion 220, and the light-transmitting portion 210 is connected to the side of the blocking portion 220 near the outer side of the lamp housing 20. The sidewall of the outer ring of the blocking portion 220 is connected to the mounting member 100. Thus, a weight-reducing space is formed between the blocking portion 220 and the light-transmitting portion 210, making the lamp assembly 10 lighter.

[0051] In order for the light emitted by the light-emitting body 30 to shine onto the light-transmitting component 200, see Figure 9 and Figure 10 In some embodiments, the light-transmitting element 200 has a focusing groove 211, which is oriented towards the light-emitting element 30. Further, the opening of the focusing groove 211 faces the light-emitting element 30. The light-emitting element 30 is mounted at the bottom of the housing groove 20A of the lamp housing 20. To allow more light to pass through the light-transmitting element 200, in some embodiments, the width of the focusing groove 211 gradually increases from the bottom to the opening. By increasing the width of the focusing groove 211 on the opening side, more light is directed towards the focusing groove 211. To refract light, in some embodiments, the bottom of the focusing groove 211 protrudes towards the opening side, and the surface of the bottom of the focusing groove 211 is an arc surface. The focusing groove 211 is located in the light-transmitting portion 210. The arc-shaped protrusion at the bottom of the focusing groove 211 effectively controls the proportion of light distribution, thereby reducing glare. To better diffuse the refracted light, a light-expanding groove 212 is further formed on the side of the light-transmitting portion 210 facing the outer side of the lamp housing 20 to refract and diffuse the light. Furthermore, the width of the light-expanding groove 212 gradually increases from the bottom of the groove towards the outer side near the lamp fixture. To refract the light in the light-transmitting portion 210, the bottom of the light-expanding groove 212 protrudes towards the opening of the groove, and the surface of the bottom of the light-expanding groove 212 is an arc surface. To diffuse the light passing through the light-transmitting body, in some embodiments, the angle between the sidewall and the bottom of the diffusion groove is greater than the angle between the sidewall and the bottom of the focusing groove 211. Furthermore, the width of the opening of the diffusion groove is greater than the width of the opening of the focusing groove 211. By using the bottom of the arc-shaped focusing groove 211 or the bottom of the arc-shaped expanding groove 212, the glare problem is reduced. Relying on the excellent anti-glare performance of the light-transmitting element 200 itself, the problem of central glare on the surface of the light-transmitting element 200 is solved, thereby reducing the overall height of the lamp.

[0052] To facilitate the rotation and adjustment of the light-transmitting component 200 within the mounting groove 130, see [reference needed]. Figure 9and Figure 10 In some embodiments, the width of the mounting groove 130 gradually increases from the side near the outer side of the lamp housing 20 to the side near the inner side of the lamp housing 20, and the width of the light-transmitting element 200 gradually increases from the side near the outer side of the lamp housing 20 to the side near the inner side of the lamp housing 20. To allow for smoother rotation of the light-transmitting element 200, in some embodiments, the groove surface of the mounting groove 130 corresponds to the outer wall of the light-transmitting element 200. For example, when the outer wall of the light-transmitting element 200 is spherical, the groove surface of the mounting element 100 is spherical; when the outer wall of the light-transmitting element 200 is cylindrical, the groove surface of the mounting element 100 is cylindrical. For more flexible rotation of the light-transmitting element 200, see [link to relevant documentation]. Figure 8 In some embodiments, the outer surface of the light-transmitting element 200 is an arc surface, and the groove surface of the mounting groove 130 surrounds the outer surface of the light-transmitting element 200. Further, the groove surface of the mounting groove 130 is an annular surface. To facilitate rotation of the light-transmitting element 200 relative to the mounting component, in some embodiments, the center of the circle containing the light-transmitting element 200 coincides with the center of the circle containing the groove surface of the mounting groove 130. To further facilitate rotation of the light-transmitting element 200 relative to the mounting component, the radius of the circle containing the light-transmitting element 200 is equal to or smaller than the radius of the circle containing the groove surface of the mounting groove 130.

[0053] To achieve adjustment of the light distribution direction, in some embodiments, the mounting member 100 is provided with a first swing angle portion, and the light-transmitting member 200 is provided with a second swing angle portion, with the first swing angle portion and the second swing angle portion rotatably connected. When the second swing angle portion rotates relative to the first swing angle portion, the light-transmitting member 200 rotates relative to the mounting member 100, thereby changing the polarization direction.

[0054] To achieve a rotatable connection between the mounting component 100 and the light-transmitting component 200, see [reference needed]. Figure 8 and Figure 10In some embodiments, the first swaying corner portion includes a swaying corner mounting hole 150, and the second swaying corner portion includes a swaying corner light-transmitting protrusion 221, the swaying corner light-transmitting protrusion 221 being rotatably disposed in the swaying corner mounting hole 150; and / or, the first swaying corner portion includes a swaying corner mounting protrusion 110, and the second swaying corner portion includes a swaying corner light-transmitting hole, the swaying corner mounting protrusion 110 being rotatably disposed in the swaying corner light-transmitting hole; and / or, the first swaying corner portion includes a swaying corner mounting protrusion 110, and the second swaying corner portion includes a swaying corner light-transmitting hole, the swaying corner mounting protrusion 221 being slidably disposed in the swaying corner mounting hole; and / or, the first swaying corner portion includes a swaying corner mounting protrusion 110, and the second swaying corner portion includes a swaying corner light-transmitting hole, the swaying corner mounting protrusion 110 being slidably disposed in the swaying corner light-transmitting hole. The first swaying corner portion may be disposed on the outer peripheral edge of the mounting member 100, and the second swaying corner portion may be disposed on the light-shielding portion of the light-transmitting member 200, to prevent the first and second swaying corner portions from blocking light. To save space in the placement of the angle-mounted light-transmitting protrusion 221, in one embodiment, the angle-mounted light-transmitting protrusion 221 passes through the angle mounting hole 150 and the lamp housing rotation groove 20B. To reduce the space required for the lamp housing rotation groove 20B, in one embodiment, the angle-mounted light-transmitting protrusion 221 and the mounting protrusion 110 are located on the same circumference. Further, the angle-mounted light-transmitting protrusion 221 and the mounting protrusion 110 are located on the circumference of the lamp housing rotation groove 20B.

[0055] In this application, the connection between the mounting component 100 and the lamp housing 20, and the connection between the light-transmitting element and the mounting component 100, are all achieved by using the structure of the mounting component 100 and the light-transmitting element 200 themselves, without the need for screw installation. This reduces the number of connecting components in the lamp, making the lamp integrated and improving assembly efficiency.

[0056] To make the rotation of the light-transmitting element 200 more stable, in some embodiments, a first sway angle portion is provided on each side of the mounting member 100, and a second sway angle portion is provided on each side of the light-transmitting element 200, with each first sway angle portion rotatably connected to a second sway angle portion. For example, see... Figure 4 Angle mounting holes 150 are provided on both sides of the mounting component 100, and angle light-transmitting protrusions 221 are provided on both sides of the light-transmitting component 200. Each angle light-transmitting protrusion 221 is rotatably mounted in an angle mounting hole 150.

[0057] For ease of assembly of mounting component 100 and light-transmitting component 200, see [link / reference] Figure 2 and Figure 3In some embodiments, a mounting slot 151 is provided on one side of the sway angle mounting hole 150, and the mounting slot 151 extends to the edge of the mounting member 100; and / or, a light-transmitting slot is provided on one side of the sway angle light-transmitting hole, and the light-transmitting slot extends to the edge of the light-transmitting member 200. Thus, by fitting the sway angle light-transmitting protrusion 221 from the mounting slot 151 into the sway angle mounting hole 150, and fitting the sway angle mounting protrusion 110 from the light-transmitting slot into the sway angle light-transmitting hole, a rotatable connection between the mounting member 100 and the light-transmitting member 200 is achieved.

[0058] To prevent the mounting component 100 and the light-transmitting component 200 from detaching, see [reference needed]. Figure 4 and Figure 8 In some embodiments, the width of the end of the sway angle light-transmitting protrusion 221 away from the light-transmitting element 200 is greater than the diameter of the sway angle mounting hole 150; and / or, the width of the end of the sway angle mounting protrusion 110 away from the mounting element 100 is greater than the diameter of the sway angle light-transmitting hole.

[0059] For easier observation of the swing angle of the light-transmitting component 200, please refer to... Figure 11 In some embodiments, the light-transmitting element 200 is provided with a swing angle indicator scale 222, which is used to identify the swing angle of the light-transmitting element 200. The swing angle indicator scale 222 is pre-marked on the light-transmitting element 200 according to its position relative to the mounting element 100 at different swing angles. To facilitate indicating the swing angle of the light-transmitting element 200, in some embodiments, a swing angle indicator scale 222 corresponding to a preset swing angle is provided on the light-transmitting element 200 according to its position at a preset swing angle. There are at least two preset swing angles, and the angles corresponding to two different preset swing angles are different. To more reasonably indicate different swing angles, in some embodiments, the swing angle indicator scale 222 is determined based on the difference between the initial swing angle and the preset swing angle. For example, if the initial swing angle is selected as 5 degrees and the preset swing angle difference is 5 degrees, then the swing angle indicator scales 222 are determined to be 5 degrees, 10 degrees, 15 degrees, 20 degrees, and 25 degrees, respectively. The preset swing angle difference is the angle difference between two adjacent preset swing angles. To facilitate observation of the swing angle indicator marks, in some embodiments, the swing angle indicator scale 222 corresponding to each preset swing angle is disposed on the same side of the light-transmitting element 200. For convenience in marking the swing angle indicator scale 222 on the light-transmitting element 200, see [link to documentation]. Figure 11 In some embodiments, the swing angle indicator scale 222 is provided along the rotational direction of the light-transmitting element 200 relative to the mounting member 100. The swing angle of the light-transmitting element 200 can be determined by observing the relative position of the swing angle indicator scale 222 and the mounting member 100. For example, the swing angle of the light-transmitting element 200 can be determined by observing the edge of the swing angle indicator scale 222 relative to the mounting member 100.

[0060] For a more intuitive indication of the angle of the light-transmitting element 200, see [link / reference]. Figure 8 In some embodiments, the mounting member 100 is provided with a swing angle indicator 160, which faces the swing angle indicator scale 222. In order to reduce the space occupied by the swing angle indicator 160, in some embodiments, the swing angle indicator 160 is provided at the edge of the mounting member 100.

[0061] To fix the adjusted position of the light-transmitting element 200, in some embodiments, the mounting member 100 is provided with a first positioning part, and the light-transmitting element 200 is provided with a second positioning part, with the first and second positioning parts movably connected. After the position of the light-transmitting element 200 is adjusted, the relative positions of the mounting member 100 and the light-transmitting element 200 are fixed by connecting the first and second positioning parts. To reduce the combined space of the mounting member 100 and the light-transmitting element 200, in some embodiments, the first positioning part is located on the side of the mounting member 100 facing the light-transmitting element 200, and the second positioning part is located on the side of the light-transmitting element 200 facing the mounting member 100. Further, the first positioning part is located on the side wall within the ring of the mounting member 100, and the second positioning part is located on the light-shielding part of the light-transmitting element 200. To stabilize the relative positions of the light-transmitting element 200 and the mounting member 100, in some embodiments, the second positioning part is arranged along the rotation direction of the light-transmitting element 200 relative to the mounting member 100, and the first positioning part is located on one side of the second positioning part.

[0062] To achieve the movable connection between the first positioning part and the second positioning part, in some embodiments, the first positioning part and the second positioning part are snapped together. To fix the relative positions of the light-transmitting element 200 and the mounting element 100 at different preset swing angles, in some embodiments, the second positioning part includes at least two snap-fit ​​points, each snap-fit ​​point being set according to the position of the light-transmitting element 200 at a preset swing angle, such that each snap-fit ​​point corresponds to a preset swing angle of the light-transmitting element 200. To facilitate adjustment of the snap-fit ​​position of the light-transmitting element 200 and the mounting element 100, in some embodiments, the material of the blocking part 220 of the light-transmitting element 200 and the mounting element 100 includes PC plastic (Polycarbonate). This makes the light-transmitting element 200 and the mounting element 100 more wear-resistant and heat-resistant, and the first positioning part and the second positioning part more resilient, facilitating the snap-fit ​​between the first positioning part and the second positioning part.

[0063] For easy adjustment of the snap-fit ​​position between the light-transmitting element 200 and the mounting element 100, see [reference needed]. Figure 8 and Figure 10In some embodiments, the second positioning part includes at least two positioning slots 223, and the first positioning part includes a positioning protrusion 170, which engages with the positioning slots 223. To facilitate sliding of the positioning protrusion 170 on each positioning slot 223, in some embodiments, the surface of the positioning protrusion 170 is curved, and the groove surface of the positioning slot 223 is also curved. To reduce effort in rotating the light-transmitting element 200, in some embodiments, effort-saving notches 180 are provided on both sides of the first positioning part, and the two sides of the first positioning part are respectively separated from the main body of the mounting member 100. Furthermore, each effort-saving notch 180 extends along the rotation direction of the light-transmitting element 200. Furthermore, the effort-saving notch 180 is arc-shaped. Thus, since the two sides of the first positioning part are separated from the main body of the mounting member 100, the positioning protrusion 170 can more easily press against or disengage from the positioning slots 223.

[0064] See Figure 11 In some embodiments, each positioning slot 223 is arranged along the rotation direction of the light-transmitting element 200, and the angles of the swing angles corresponding to two different positioning slots 223 are different. In order to accommodate the rotation of the light-transmitting element 200, each positioning slot 223 is further formed circumferentially on the outer side of the light-transmitting element 200. In order to fix the position of the light-transmitting element 200 at each preset swing angle, each positioning slot 223 is further determined according to the position of the light-transmitting element 200 at each preset swing angle, and the positioning slot 223 corresponds to a preset swing angle, with each positioning slot 223 corresponding to a preset swing angle.

[0065] To reduce the rotation space of the light-transmitting element 200, see [reference needed]. Figure 6 , Figure 9 and Figure 10 In some embodiments, the light-transmitting element 200 has a rotation notch 224, and the rotation notch 224 and the second positioning part are located on both sides of the rotation axis of the light-transmitting element 200. When the light-transmitting element 200 rotates towards the rotation notch 224, the rotation of the light-transmitting element 200 is not restricted by the lamp housing 20 because of the rotation notch 224. At the same time, there is no need to reserve more space in the lamp housing 20 for the rotation of the light-transmitting element 200, so the size of the lamp housing 20 can be reduced, making the lamp smaller. Further, the rotation notch 224 is formed in the light-shielding part of the light-transmitting element 200. In order to accommodate the rotation of the light-transmitting element 200, in some embodiments, the cross-section of the rotation notch 224 is fan-shaped at the cross-section where the second positioning part and the rotation notch 224 are located. In order to avoid the lamp housing 20 from obstructing the rotation of the light-transmitting element 200, in some embodiments, the angle of the central angle of the rotation notch 224 is greater than or equal to the maximum value of each preset swing angle.

[0066] In some embodiments, see Figure 9 and Figure 10The luminaire assembly 10 also includes a reflector 300, which is connected to the lamp housing 20 and reflects light passing through the light-transmitting element 200 to the outside of the lamp housing 20. In some embodiments, the reflector 300 is disposed on the side near the outside of the lamp housing 20, and the mounting member 100 and the light-transmitting element 200 are disposed on the side near the inside of the lamp housing 20.

[0067] For easy connection between reflector 300 and lamp housing 20, see [link / reference] Figure 3 and Figure 9 In some embodiments, the reflector cup 300 is used to snap onto the lamp housing 20. Since the light-transmitting element 200 is located inside the lamp housing 20, in order to facilitate the adjustment of the light-transmitting element 200, in some embodiments, the reflector cup 300 is disposed in the housing groove 20A of the lamp housing 20, and the reflector cup 300 snaps onto the side wall of the housing groove 20A.

[0068] To reflect light off the outside of the light fixture, see Figure 9 and Figure 10 In some embodiments, the reflector cup 300 has a reflective channel 310, with one side of the reflective channel 310 facing the light-transmitting element 200 and the other side facing the outside of the lamp. In order to diffuse the light, the width of the reflective channel 310 gradually increases from the side closer to the light-transmitting element 200 to the side closer to the outside of the lamp.

[0069] See Figure 12 In one embodiment, when the light-transmitting element is at a 24-degree angle, the light spot below is observed when the lamp is directly illuminated (i.e., the sway angle is 0 degrees). See [link to previous embodiment]. Figure 13 The wall-washing light pattern under direct illumination from the light fixture when the light-transmitting element is at a 24-degree angle. Figure 12 and Figure 13 As can be seen, when the light-transmitting element is 24 degrees, the light spot is evenly distributed under direct illumination from the lamp.

[0070] See Figure 14 In one embodiment, when the light-transmitting element is at 24 degrees, under direct illumination from the lamp, the light intensity of the light spot at different locations is simulated when the light-transmitting element is at 23.5 degrees. Figure 14 It can be seen that within the beam angle range, the light intensity transitions uniformly, and the light intensity is the same at corresponding positions on both sides of the luminaire. The light intensity is greatest directly below the light source, reaching 8056.0 cd. Moreover, when the light-transmitting element is at 24 degrees, under direct illumination, the total collected power is 1391.0 lm, and the efficiency is 0.81582, indicating high light source efficiency.

[0071] See Figure 15 In one embodiment, when the light-transmitting element is at 24 degrees and the swing angle of the light-transmitting element is 25 degrees, the light spot at the wall washing area is evenly distributed.

[0072] See Figure 16 In one embodiment, when the light-transmitting element is at a 24-degree angle and the swing angle of the light-transmitting element is 25 degrees, the light intensity of the light spot at different positions is... Figure 16 The curve centered on the 25-degree line corresponds to the curve when the light-transmitting element is at a 24-degree angle and the swing angle of the light-transmitting element is 25 degrees. Figure 16 It can be seen that the light intensity transitions uniformly within the beam angle range. Among these, Figure 16 The curve centered on the 0-degree line represents the light intensity of the light spot at different positions under direct illumination of the luminaire when the light-transmitting element is at 24 degrees.

[0073] See Figure 17 In one embodiment, when the light-transmitting element is at an angle of 36 degrees, the lower light spot is observed under direct illumination from the lamp. See [link / reference]. Figure 18 The light spot observed at the wall washer area when the light-transmitting element is at a 36-degree angle and the light fixture shines directly on the wall. Figure 17 and Figure 18 As can be seen, when the light-transmitting element is at an angle of 36 degrees, the light spot is evenly distributed under direct illumination from the lamp.

[0074] See Figure 19 In one embodiment, when the light-transmitting element is at an angle of 36 degrees, the light intensity of the light spot at different positions under direct illumination from the luminaire is shown. Figure 19 It can be seen that within the beam angle range, the light intensity transitions evenly, and the light intensity is the same at corresponding positions on both sides of the lamp. Figure 19 In the figure, the two curves represent the light intensity of the luminaire on the C0 / 180 and C90 / 270 planes, respectively. It can be seen that the two curves basically overlap, indicating that when the light-transmitting element is 36 degrees, the light intensity of the luminaire is evenly distributed in different directions under direct illumination.

[0075] See Figure 20 In one embodiment, when the light-transmitting element is at 36 degrees and the swing angle of the light-transmitting element is 25 degrees, the light spot at the wall washing area is evenly distributed.

[0076] See Figure 21 In one embodiment, when the light-transmitting element is at a 36-degree angle and the swing angle of the light-transmitting element is 25 degrees, the light intensity of the light spot at different positions is... Figure 21 The curve deviating from the 0-degree line corresponds to the curve when the light-transmitting element is at 24 degrees and the swing angle of the light-transmitting element is 25 degrees. (From...) Figure 21 It can be seen that, within the beam angle range, the illuminance transitions relatively uniformly on both sides of the luminaire. Among these, Figure 21 The curve centered on the 0-degree line represents the light intensity of the light spot at different positions under direct illumination of the luminaire when the light-transmitting element is at an angle of 36 degrees.

[0077] See Figure 22In one embodiment, when the light-transmitting element is at a 50-degree angle, the lower light spot is observed under direct illumination from the lamp. See [link / reference]. Figure 23 The light spot observed at the wall washer area when the light-transmitting element is at a 50-degree angle and the light fixture shines directly on it. Figure 22 and Figure 23 As can be seen, when the light-transmitting element is at an angle of 50 degrees, the light spot is evenly distributed under direct illumination from the lamp.

[0078] See Figure 24 In one embodiment, when the light-transmitting element is at a 50-degree angle, the light intensity of the light spot at different positions under direct illumination from the lamp is shown. Figure 24 It can be seen that within the beam angle range, the light intensity transitions evenly, and the light intensity at corresponding positions on both sides of the lamp is roughly the same, with the maximum light intensity being 2095.7 cd. Figure 24 In the figure, the two curves represent the light intensity of the luminaire on the C0 / 180 and C90 / 270 planes, respectively. It can be seen that the two curves basically overlap, indicating that when the light-transmitting element is 50 degrees, the light intensity of the luminaire is evenly distributed in different directions under direct illumination.

[0079] See Figure 25 In one embodiment, when the light-transmitting element is at 50 degrees and the swing angle of the light-transmitting element is 15 degrees, the light spot at the wall washing area is evenly distributed.

[0080] See Figure 26 In one embodiment, when the light-transmitting element is at a 50-degree angle and its swing angle is 25 degrees, the light spot at the wall washing area is evenly distributed. The light spot at a swing angle of 25 degrees is more evenly distributed than the light spot at a swing angle of 15 degrees.

[0081] See Figure 27 In one embodiment, when the light-transmitting element is at a 50-degree angle and the swing angle of the light-transmitting element is 15 degrees, the light intensity of the light spot at different positions is... Figure 27 The curve deviating from the 0-degree line corresponds to the curve when the light-transmitting element is 50 degrees and the swing angle of the light-transmitting element is 15 degrees. (From...) Figure 27 It can be seen that within the beam angle range, the light intensity transitions uniformly, and the light intensity at corresponding positions on both sides of the luminaire is approximately the same. The maximum light intensity is 1997.9 cd, and the light efficiency is 0.79522. Among these, Figure 27 The curve centered on the 0-degree line represents the light intensity of the light spot at different positions under direct illumination of the luminaire when the light-transmitting element is at 50 degrees.

[0082] See Figure 28 In one embodiment, when the light-transmitting element is at a 50-degree angle and the swing angle of the light-transmitting element is 25 degrees, the light intensity of the light spot at different positions is... Figure 28The curve deviating from the 0-degree line corresponds to the curve when the light-transmitting element is at 50 degrees and the swing angle of the light-transmitting element is 25 degrees. (From...) Figure 28 It can be seen that within the beam angle range, the light intensity transitions uniformly, and the light intensity at corresponding positions on both sides of the luminaire is approximately the same. The maximum light intensity is 1770.2 cd, and the light efficiency is 0.73773. Among these, Figure 28 The curve centered on the 0-degree line represents the light intensity of the light spot at different positions under direct illumination of the luminaire when the light-transmitting element is at 50 degrees.

[0083] See Figure 29 In one embodiment, in the indoor luminaire light distribution curve diagram, the curve corresponding to c0 / 180 and the curve corresponding to c90 / 270 basically overlap, indicating that the light distribution is the same on two planes perpendicular to the luminaire, and the luminaire can achieve the same level of illumination in different directions. In another embodiment, below the luminaire, the isolux curves are relatively smooth, and the light intensity transitions evenly. The curves corresponding to different illuminances change uniformly, and when the power of the light-emitting body changes, the change in light intensity is uniform, avoiding the discomfort caused by sudden changes in luminous intensity.

[0084] See Figure 30 In one embodiment, under different ceiling heights, different distances between the wall and the light fixture, and different work surfaces, the UGR value corresponding to each location point in the space below the light fixture is less than or equal to 6. This means that when the distance between the human eye and the light fixture changes in both the vertical and horizontal directions, the UGR value remains less than or equal to 6, and the illumination from the light fixture will not cause eye discomfort in different situations and positions. Even under different spacing light layouts, the change in UGR value caused by the observer's position is less than 8, avoiding the problem of glare caused by the light emitted by the light fixture.

[0085] To adjust the beam angle, see [link / reference]. Figure 31 and Figure 32In one embodiment, the lamp assembly 10 further includes a lamp housing 20, which includes an inner housing 201 and an outer housing 202. The inner housing 201 has a housing groove 20A, and the outer housing 202 has a sliding groove 2021. The inner housing 201 is slidably disposed in the sliding groove 2021, and the inner housing 201 and the outer housing 202 are movably connected. The inner housing 201 has a light hole 2011, which communicates with the housing groove 20A. The outer housing 202 has a light-positioning block 2022, which is movably disposed through the light-positioning hole 2011 and the housing groove 20A. The light-positioning block 2022 is used to mount the light-emitting element 30. By sliding the inner housing 201 in the sliding groove 2021, the position of the light-transmitting element is adjusted, thereby changing the distance between the light-transmitting element 200 and the light-emitting element 30, achieving zooming, and thus adjusting the beam angle to make the light spot transition uniform. Moreover, the beam angle can be adjusted without disassembling the lamp or replacing the light-transmitting element 200. The mounting component 100 and the light-transmitting component 200 are disposed in the shell groove 20A of the inner shell 201. In one embodiment, after the inner shell 201 is adjusted in position in the sliding groove 2021, the inner shell 201 and the outer shell 202 can be fixed by snap-fit ​​and screw-fit, thereby fixing the position of the inner shell 201 in the sliding groove 2021 and selecting the corresponding beam angle. It should be understood that the beam angle can be adjusted by the distance between the light-emitting element 30 and the light-transmitting component 200, so when the inner shell 201 slides to different positions in the sliding groove 2021, the corresponding beam angle is different, thereby realizing the adjustment of the beam angle.

[0086] To achieve a movable connection between the inner shell 201 and the outer shell 202, in one embodiment, the sidewall of the sliding groove 2021 is provided with an outer shell protrusion 2023, and the sidewall of the inner shell 201 is provided with an inner shell groove 2012. The outer shell protrusion 2023 is engaged with the inner shell groove 2012. There are at least two outer shell protrusions 2023 and / or inner shell grooves 2012, and the outer shell protrusions 2023 and / or inner shell grooves 2012 are arranged along the light direction. Specifically, there may be one outer shell protrusion 2023 and two or more inner shell grooves 2012; or, there may be two or more outer shell protrusions 2023 and one inner shell groove 2012; or, there may be two or more outer shell protrusions 2023 and two or more inner shell grooves 2012 respectively. By engaging the outer shell protrusion 2023 with different inner shell grooves 2012, or by creating different outer shell protrusions 2023 within the inner shell grooves 2012, the position of the inner shell 201 relative to the outer shell 202 is changed, thereby altering the distance between the light-transmitting element 200 and the light-emitting element 30, achieving zooming and adjusting the beam angle. To achieve switching between different beam angles, in one embodiment, the beam angles corresponding to two different inner shell grooves 2012 on the inner shell 201 are different; or, the beam angles corresponding to two different outer shell protrusions 2023 on the outer shell 202 are different; or, the beam angles corresponding to the engaging combinations between each outer shell protrusion 2023 on the outer shell 202 and each inner shell groove 2012 on the inner shell 201 are different. When there is one outer shell protrusion 2023 and two or more inner shell grooves 2012, the beam angles corresponding to two different inner shell grooves 2012 are different. When there is one inner shell groove 2012 and two or more outer shell protrusions 2023, the beam angles corresponding to two different outer shell protrusions 2023 are different. When there are two or more outer shell protrusions 2023 and inner shell grooves 2012, the relative positions of outer shell 202 and inner shell 201 can be changed through various snap-fit ​​combinations between outer shell protrusions 2023 and inner shell grooves 2012, thereby achieving zoom and adjusting the beam angle.

[0087] To achieve the movable connection between the inner shell 201 and the outer shell 202, in one embodiment, the side wall of the sliding groove 2021 is provided with an outer shell groove, and the side wall of the inner shell 201 is provided with an inner shell protrusion. The inner shell protrusion is engaged with the outer shell groove, and there are at least two outer shell grooves and / or inner shell protrusions. Each outer shell groove and / or each inner shell protrusion is arranged along the light direction. By engaging the inner shell protrusion with different outer shell grooves or providing different inner shell protrusions in the outer shell grooves, the position of the inner shell 201 relative to the outer shell 202 is changed, thereby changing the distance between the light-transmitting element 200 and the light-emitting element 30, achieving zooming, and adjusting the beam angle. To achieve the switching between different beam angles, in one embodiment, the beam angles corresponding to two different inner shell protrusions on the inner shell 201 are different; or, the beam angles corresponding to two different outer shell grooves on the outer shell 202 are different; or, the beam angles corresponding to the engaging combinations between each outer shell groove on the outer shell 202 and each inner shell protrusion on the inner shell 201 are different.

[0088] To achieve switching between the two beam angles, see [link / reference]. Figure 31 and Figure 32 In one embodiment, the sidewall of the sliding groove 2021 is provided with a shell protrusion 2023, and the sidewall of the inner shell 201 is provided with two inner shell grooves 2012. The two inner shell grooves 2012 are arranged along the light direction, wherein one inner shell groove 2012 corresponds to a first preset beam angle, and the other inner shell groove 2012 corresponds to a second preset beam angle. The beam angle corresponding to the inner shell groove 2012 near the groove opening is greater than the beam angle corresponding to the inner shell groove 2012 near the groove bottom. See also... Figure 31 and Figure 32 In one embodiment, the beam angle corresponding to the inner shell groove 2012 near the opening of the shell groove is 36 degrees, and the beam angle corresponding to the inner shell groove 2012 near the bottom of the shell groove is 24 degrees. See also Figure 33 When the outer shell protrusion 2023 is engaged with the inner shell groove 2012 near the opening of the shell groove, the distance between the light-emitting element and the light-transmitting element is small, and the beam angle is large, with a beam angle of 36 degrees. (See also...) Figure 34 When the outer shell protrusion 2023 is engaged with the inner shell groove 2012 near the bottom of the shell groove, the distance between the light-emitting element and the light-transmitting element is relatively large, and the beam angle is relatively small, with a beam angle of 24 degrees. (See also...) Figure 35 and Figure 36 The beam angles are 36 degrees and 24 degrees, respectively, and the transition between the two beam angles is uniform. (See also...) Figure 37 and Figure 38 When the beam angles are 36 degrees and 24 degrees respectively, the light intensity at the same position is relatively small, avoiding sudden changes in light intensity that could cause discomfort to the human eye.

[0089] Corresponding to the aforementioned application function implementation method embodiments, this application also provides a lamp and corresponding embodiments.

[0090] See Figure 2 , Figure 9 and Figure 10 One embodiment of the luminaire includes the luminaire components of any of the above embodiments.

[0091] To mount the light-emitting element in the housing slot, in some embodiments, a light source bracket is connected to the bottom of the housing slot. This light source bracket is used to mount the light-emitting element. The light source bracket can be installed in the lamp housing using screws. For adjusting the beam angle, see [link to relevant documentation]. Figure 31 and Figure 32 In one embodiment, the light source support is disposed on the light-positioning block.

[0092] For heat dissipation of the light fixtures, see Figure 2 In some embodiments, the luminaire also includes a heat sink 50 disposed on the lamp housing 20.

[0093] In some embodiments, the light source includes LED lamps, halogen lamps, and incandescent lamps.

[0094] Compared with the prior art, the present invention has at least the following advantages: 1. By rotating the mounting component, both the mounting component and the light-transmitting component rotate relative to the lamp housing. Rotating the light-transmitting component causes it to rotate relative to the mounting component. The direction of rotation of the light-transmitting component caused by rotating the mounting component is different from the direction of rotation of the light-transmitting component itself. Therefore, the light-transmitting component can rotate independently in two directions, enabling horizontal and vertical light distribution adjustment. The light-transmitting component can achieve 360-degree light distribution adjustment in the horizontal plane, thereby adjusting the angle of tangential light relative to the wall. The light-transmitting component can achieve 0-35 degree light distribution adjustment in the vertical plane.

[0095] 2. Since the mounting components and light-transmitting components are installed within the housing groove of the lamp housing, there is no need to move or reinstall the lamp housing when rotating the mounting components and light-transmitting components. The rotation of the mounting components and light-transmitting components is not restricted by objects outside the lamp housing, and objects outside the lamp housing cannot obstruct the rotation of the mounting components and light-transmitting components, thus reducing the space required for lamp installation.

[0096] 3. The lighting components are installed within the housing groove, without sacrificing the light distribution adjustment function or requiring connecting elements. Connection is achieved through the structure of the light-transmitting element and the mounting components themselves, resulting in a simple and clean appearance. This makes assembly of the lighting fixture more convenient and improves assembly efficiency.

[0097] 4. Polarization can be adjusted from 0 to 35 degrees by adjusting the degree of the light-transmitting element.

[0098] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
