Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lighting, in particular to a lamp assembly and a lamp. BACKGROUND

[0002] A lamp usually comprises a lamp shell, a light emitter, a light reflecting cup and a light transmitting piece. The light emitter, the light reflecting cup and the light transmitting piece are installed in the lamp shell. The light emitted by the light emitter passes through the light reflecting cup and the light transmitting piece in sequence. In order to adjust the light distribution direction, the whole lamp is pivotally connected to a wall body, for example, the two sides of the lamp shell are pivotally connected to the wall body. Thus, the light distribution direction can be adjusted by swinging the angle of the lamp. However, the lamp can only be rotated in one direction, and the light distribution direction cannot be flexibly adjusted.

[0003] A patent with the patent number 202011342945.3 discloses an optical module capable of adjusting light distribution. The optical module comprises a first cylinder, a second cylinder and a polarizing lens body. The first cylinder and the second cylinder are pivotally connected. The polarizing lens body is pivotally arranged in the inner cavity of the first cylinder. The polarizing lens body is provided with a guide positioning part on the edge perpendicular to the rotation axis. The second cylinder is provided with an inclined guide slot hole. The guide positioning part and the guide slot hole are in sliding fit connection. By rotating the first cylinder, the polarizing lens body can be synchronously rotated with the first cylinder in the horizontal plane. At the same time, due to the guide action of the guide positioning part on the polarizing lens body on the guide slot hole of the second cylinder, the polarizing lens body is flipped by a certain angle relative to its rotation axis in the vertical plane, thereby realizing the adjustment of the angle of light distribution in the vertical plane. However, the adjustment of the polarizing lens body in the horizontal and vertical directions is mutually restricted, and the light distribution adjustment in the horizontal and vertical directions cannot be performed independently.

[0073] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0074] Referring to 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 configured to be rotatably mounted in a lamp housing 20. The light-transmitting member 200 is rotatably mounted on the mounting member 100. The mounting member 100 is configured to be rotatably mounted in a housing groove 20A of the lamp housing 20. The light-transmitting member 200 is configured to be disposed in the housing groove 20A of the lamp housing 20. The light-transmitting member 200 is configured to transmit light emitted by a light emitter 30 to a light-reflecting cup 300 for reflecting the light out of the lamp housing 20.

[0075] The lamp housing 20 is mounted on a mounting wall. The lamp housing 20 is in contact with the mounting wall. The mounting member 100 is spaced apart from the mounting wall. The mounting member 100 is rotatable in the lamp housing 20. The rotation of the mounting member 100 is not limited by the mounting wall. The light-transmitting member 200 is configured to transmit light to the light-reflecting cup 300 or outside of the lamp. The light emitter 30 is mounted in the lamp housing 20. The position of the light emitter 30 is adjusted so that the light emitted by the light emitter 30 is transmitted to the light-transmitting member 200. The light-transmitting member 200 is mounted on the mounting member 100. When the mounting member 100 is rotated, the light-transmitting member 200 is rotated in the same direction, so that the light distribution direction is adjusted. The light-transmitting member 200 is independently rotatable relative to the mounting member 100. The light-transmitting member 200 is rotatable in a direction different from the direction in which the mounting member 100 is rotated. Thus, the light-transmitting member 200 is rotatable in two directions. The position of the light-transmitting member 200 in the two directions is adjusted. The light distribution in the horizontal and vertical directions is adjusted. The rotation of the light-transmitting member 200 in the two directions is independent of each other. Thus, the light distribution in the horizontal and vertical directions is independently adjusted. The light-transmitting member 200 and the mounting member 100 are fixed relative to each other by static friction. That is, the light-transmitting member 200 and the mounting member 100 are fixed by being tightly attached to each other.

[0076] The present application assembles the light-transmitting member 200 and the mounting member 100, so that the light direction can be adjusted by the light-transmitting body of the lamp assembly 10, and the light distribution direction can be adjusted in the vertical and horizontal directions by the rotation of the lamp assembly 10, so that the light distribution direction is accurate and clear, and the target area position of the lamp assembly 10 is accurately irradiated, so that the adjustment of the lamp is integrated. By rotating the light-transmitting body, the switching between symmetrical and asymmetrical light spots can be realized, and the switching process is uniform.

[0077] Referring to Figure 1 , the light distribution adjustment is realized by the rotation of the light-transmitting member 200, Figure 1 The left side is the irradiation of the lamp under direct illumination, Figure 1 The right side of the lamp is the irradiation of the lamp after the rotation of the light-transmitting member 200 relative to the mounting member 100.

[0078] In order to make the rotation direction of the mounting member 100 and the rotation direction of the light-transmitting member 200 relative to the mounting member 100 different, referring to Figures 7 to 9 In some embodiments, the rotation axis of the mounting member 100 intersects or is out of the plane with the rotation axis of the light-transmitting member 200, so as to adjust the included angle of the light with two different directions by rotating the mounting member and the light-transmitting member. When the rotation axis of the mounting member 100 intersects the rotation axis of the light-transmitting member 200, the rotation axis of the mounting member 100 and the rotation axis of the light-transmitting member 200 are located on the same plane, and the rotation direction of the mounting member 100 and the rotation direction of the light-transmitting member 200 are different, which can realize the polarization adjustment of the light-transmitting member 200 in the horizontal and vertical directions. When the rotation axis of the mounting member 100 is out of the plane with the rotation axis of the light-transmitting member 200, the rotation axis of the mounting member 100 and the rotation axis of the light-transmitting member 200 are located on different planes, so that the rotation directions of the mounting member 100 and the light-transmitting member 200 are different.

[0079] In order to facilitate the polarization adjustment of the light-transmitting member 200 in the horizontal and vertical directions, referring to Figures 9 to 10 Further, the rotation axis of the mounting member 100 and the rotation axis of the light-transmitting member 200 are perpendicular or out of the plane. Since the rotation axis of the mounting member 100 and the rotation axis of the light-transmitting member 200 are perpendicular or out of the plane, the mounting member 100 and the light-transmitting member 200 rotate independently in two directions, the component of the rotation axis of the mounting member 100 on the rotation axis of the light-transmitting member 200 is zero, and when the mounting member 100 rotates to drive the light-transmitting member 200 to rotate, the rotation component of the light-transmitting member 200 on the rotation axis of the light-transmitting member 200 is zero. The rotation of the light-transmitting member 200 in one direction keeps the position of the light-transmitting member 200 in another direction unchanged. In order to facilitate the adjustment of the polarization direction, referring to Figure 9 and Figure 10Further, 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. In order to facilitate the light emitting to 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. Further, the rotation axis of the light transmitting member 200 is perpendicular to the central axis of the reflector cup 300. Further, the rotation axis of the mounting member 100 coincides with the central axis of the lamp housing 20. Further, the rotation axis of the light transmitting member 200 is perpendicular to the central axis of the lamp housing 20.

[0080] In order to rotate the mounting member 100 to be arranged in the lamp housing 20, referring to Figure 9 and Figure 10 In some embodiments, the outer periphery of the mounting member 100 is provided with a rotating part, and the rotating part is used to rotate and connect to the lamp housing 20, so as to change the direction of the light by rotating the rotating part. In order to rotate the mounting member 100 to be arranged in the shell groove 20A of the lamp housing 20, in some embodiments, the rotating part is arranged to rotate in the shell groove 20A of the lamp housing 20.

[0081] In order to realize the rotating connection between the mounting member 100 and the lamp housing 20, referring to Figure 9 and Figure 10 In some embodiments, the rotating part includes a mounting protrusion 110, and the mounting protrusion 110 is used to be arranged to slide in the lamp housing rotating groove 20B of the lamp housing 20; and / or, the rotating part includes a mounting rotating groove, and the mounting rotating groove is used for the lamp housing protrusion of the lamp housing 20 to slide. The lamp housing rotating groove 20B is opened on the side wall of the shell groove 20A of the lamp housing 20, and the lamp housing protrusion is arranged on the side wall of the shell groove 20A of the lamp housing 20. The mounting protrusion 110 is arranged on the outer side wall of the mounting member 100, and the mounting rotating groove is opened on the outer side wall of the mounting member 100. In order to realize the 360-degree rotation of the mounting member 100, in some embodiments, the extension path of the lamp housing rotating groove 20B is circular, the lamp housing rotating groove 20B is circumferentially opened on the side wall of the shell groove 20A of the lamp housing 20, and the extension path of the mounting rotating groove is circular. The mounting rotating groove is circumferentially opened on the outer side wall of the mounting member 100. In order to facilitate the mounting of the mounting member 100 into the lamp housing 20, in some embodiments, the mounting protrusion 110 is at least two, and each mounting protrusion 110 is circumferentially arranged on the outer side wall of the mounting member 100. Further, each mounting protrusion 110 is uniformly arranged on the outer side wall of the mounting member 100. In order to make the mounting protrusion 110 slide more smoothly in the lamp housing rotating groove 20B, in some embodiments, the mounting protrusion 110 is spherical or hemispherical.

[0082] In order to facilitate the mounting of the mounting protrusion 110 into the lamp housing rotating groove 20B, referring to Figure 2 and Figure 8In some embodiments, the side wall of the mounting member 100 is provided with a press-fit hole 120, which is arranged 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 inwardly and then inserted into the lamp housing 20 so that the mounting protrusion 110 is fitted into the rotating groove 20B of the lamp housing. Further, the press-fit hole 120 is arranged at least 180 degrees around the outer periphery of the mounting protrusion 110. Further, the press-fit hole 120 is arranged around three sides of the outer periphery of the mounting protrusion 110. In each mounting protrusion 110, the outer periphery is provided with the press-fit hole 120. In order to more easily press the mounting protrusion 110, in some embodiments, the material of the mounting protrusion 110 includes plastic. Further, the material of the mounting member 100 includes plastic.

[0083] In order to avoid the light-transmitting member 200 hindering the inward pressing of the mounting protrusion 110, referring to Figure 2 , Figure 6 and Figure 7 In some embodiments, the light-transmitting member 200 is provided with a protrusion-pressing hole 225, and the mounting protrusion 110 is movably arranged in the protrusion-pressing hole 225.

[0084] In order to reduce the occupied space of the mounting member 100 and the light-transmitting member 200, referring to Figure 7 and Figure 9 In some embodiments, the mounting member 100 is annular and is sleeved on the outer periphery of the light-transmitting member 200. Further, the mounting member 100 is provided with a mounting groove 130 and a light-transmitting opening 140, the light-transmitting member 200 is rotatably arranged in the mounting groove 130, and the light-transmitting opening 140 is used for light to pass through. In this way, the light emitted by the light emitter 30 is irradiated to the light-transmitting member 200, passes through the light-transmitting member 200, is emitted from the light-transmitting opening 140 of the mounting member 100, and is irradiated to the light-reflecting cup 300.

[0085] In order to make the light pass through the light-transmitting member 200 in the mounting groove 130, referring to Figure 6 In some embodiments, the light-transmitting member 200 includes a light-transmitting part 210 and a shielding part 220 connected to each other, the shielding part 220 is arranged around the outer periphery of the light-transmitting part 210, and the shielding part 220 is rotatably connected to the mounting member 100. In order to stabilize the connection between the light-transmitting member 200 and the mounting member 100, further, the shielding part 220 is arranged around the outer periphery of the light-transmitting part 210, and the shielding part 220 surrounds the light-transmitting member 200 at least once. In order to make more light pass through the light-transmitting part 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 part 210. In order to reduce the occupied space of the mounting member 100 and the light-transmitting member 200, referring to Figure 7 In some embodiments, the width of the mounting groove 130 is greater than the width of the light-transmitting member 200. Further, the width of the mounting groove 130 is greater than the width of the shielding part 220.

[0086] In order to reduce the weight of the light-transmitting piece 200, referring to Figure 9 and Figure 10 In some embodiments, the shielding part 220 is in the shape of a ring, and the width of the shielding part 220 gradually increases from one side close to the outer side of the lamp shell 20 to the other side close to the inner side of the lamp shell 20, the light-transmitting part 210 is located in the ring of the shielding part 220, and the light-transmitting part 210 is connected to one side of the shielding part 220 close to the outer side of the lamp shell 20, and the side wall outside the ring of the shielding part 220 is connected to the mounting part 100. Thus, a weight-reducing space is enclosed between the shielding part 220 and the light-transmitting part 210, so that the lamp assembly 10 is more lightweight.

[0087] In order to make the emitted light of the light emitter 30 shine on the light-transmitting piece 200, referring to Figure 9 and Figure 10 In some embodiments, the light-transmitting piece 200 is provided with a light-collecting groove 211 for being arranged towards the light emitter 30. Further, the opening of the light-collecting groove 211 is towards the light emitter 30. The light emitter 30 is mounted at the bottom of the shell groove 20A of the lamp shell 20. In order to make more light pass through the light-transmitting piece 200, in some embodiments, the width of the light-collecting groove 211 gradually increases from the groove bottom to the opening. By increasing the width of the light-collecting groove 211 on one side of the opening, more light can shine on the light-collecting groove 211. In order to refract the light, in some embodiments, the groove bottom of the light-collecting groove 211 is convex towards one side of the opening of the light-collecting groove 211, and the surface of the groove bottom of the light-collecting groove 211 is in the shape of a circular arc. The light-collecting groove 211 is provided in the light-transmitting part 210. By the convexity of the circular arc-shaped groove bottom of the light-collecting groove 211, the light distribution ratio is reasonably controlled, which plays a role in reducing glare. In order to make the refracted light better diffuse, further, the light-transmitting part 210 is provided with a light-expanding groove 212 on one side towards the outer side of the lamp shell 20 for refracting and diffusing the light. Still further, the width of the light-expanding groove 212 gradually increases from the groove bottom to one side close to the outer side of the lamp. In order to refract the light in the light-transmitting part 210, still further, the groove bottom of the light-expanding groove 212 is convex towards one side of the opening of the light-expanding groove 212, and the surface of the groove bottom of the light-expanding groove 212 is in the shape of a circular arc. In order to diffuse the light passing through the light-transmitting part, in some embodiments, the included angle between the side wall of the light-expanding groove and the groove bottom of the light-expanding groove is greater than the included angle between the side wall of the light-collecting groove 211 and the groove bottom of the light-collecting groove 211. Further, the width of the opening of the light-expanding groove is greater than the width of the opening of the light-collecting groove 211. By the groove bottom of the light-collecting groove 211 in the shape of a circular arc or the groove bottom of the light-expanding groove 212 in the shape of a circular arc, the problem of glare is reduced, and the excellent anti-glare performance of the light-transmitting piece 200 itself solves the problem of central glare on the surface of the light-transmitting piece 200, thereby reducing the height of the whole lamp.

[0088] In order to facilitate the rotation and adjustment of the light-transmitting piece 200 in the mounting groove 130, referring to Figure 9And Figure 10 In some embodiments, the width of the mounting groove 130 gradually increases from the side close to the outer side of the lamp housing 20 to the side close to the inner side of the lamp housing 20, and the width of the light-transmitting piece 200 gradually increases from the side close to the outer side of the lamp housing 20 to the side close to the inner side of the lamp housing 20. In order to make the rotation of the light-transmitting piece 200 more smooth, in some embodiments, the groove surface of the mounting groove 130 is correspondingly arranged with the outer wall of the light-transmitting piece 200. For example, when the outer wall of the light-transmitting piece 200 is spherical, the groove surface of the mounting piece 100 is spherical; when the outer wall of the light-transmitting piece 200 is cylindrical, the groove surface of the mounting piece 100 is cylindrical. In order to make the light-transmitting piece 200 rotate more flexibly, see Figure 8 In some embodiments, the outer side surface of the light-transmitting piece 200 is a circular arc surface, and the groove surface of the mounting groove 130 surrounds the outer side surface of the light-transmitting piece 200. Further, the groove surface of the mounting groove 130 is a circular ring surface. In order to facilitate the rotation of the light-transmitting piece 200 relative to the mounting piece, in some embodiments, the center of the circle where the light-transmitting piece 200 is located coincides with the center of the circle where the groove surface of the mounting groove 130 is located. In order to facilitate the rotation of the light-transmitting piece 200 relative to the mounting piece, further, the radius of the circle where the light-transmitting piece 200 is located is equal to or less than the radius of the circle where the groove surface of the mounting groove 130 is located.

[0089] In order to realize the adjustment of the light distribution direction, in some embodiments, the mounting piece 100 is provided with a first swing angle part, and the light-transmitting piece 200 is provided with a second swing angle part, and the first swing angle part is rotationally connected with the second swing angle part. When the second swing angle part rotates relative to the first swing angle part, the light-transmitting piece 200 rotates relative to the mounting piece 100, thereby changing the polarization direction.

[0090] In order to realize the rotational connection of the mounting piece 100 and the light-transmitting piece 200, see Figure 8 And Figure 10In some embodiments, the first swing angle part comprises a swing angle installation rotating hole 150, the second swing angle part comprises a swing angle light-transmitting protrusion 221, and the swing angle light-transmitting protrusion 221 is rotationally arranged in the swing angle installation rotating hole 150; and / or, the first swing angle part comprises a swing angle installation protrusion 110, the second swing angle part comprises a swing angle light-transmitting rotating hole, and the swing angle installation protrusion 110 is rotationally arranged in the swing angle light-transmitting rotating hole; and / or, the first swing angle part comprises a swing angle installation rotating groove, the second swing angle part comprises a swing angle light-transmitting protrusion 221, and the swing angle light-transmitting protrusion 221 is slidingly arranged in the swing angle installation rotating groove; and / or, the first swing angle part comprises a swing angle installation protrusion 110, the second swing angle part comprises a swing angle light-transmitting rotating groove, and the swing angle installation protrusion 110 is slidingly arranged in the swing angle light-transmitting rotating groove. The first swing angle part can be arranged at the outer peripheral edge of the installation piece 100, and the second swing angle part is arranged at the light-shielding part of the light-transmitting piece 200, so as to avoid that the first swing angle part and the second swing angle part shield light. In order to save space for arranging the swing angle light-transmitting protrusion 221, in an embodiment, the swing angle light-transmitting protrusion 221 is arranged in the swing angle installation rotating hole 150 and the lamp shell rotating groove 20B. In order to reduce the space of the lamp shell rotating groove 20B, in an embodiment, the swing angle light-transmitting protrusion 221 and the installation protrusion 110 are located on the same circle. Further, the swing angle light-transmitting protrusion 221 and the installation protrusion 110 are located on the circle where the lamp shell rotating groove 20B is located.

[0091] In the present application, the connection between the installation piece 100 and the lamp shell 20, and the connection between the light-transmitting body and the installation piece 100 are all achieved by the structure of the installation piece 100 and the light-transmitting piece 200 themselves, without the need for screwing, so as to reduce the connecting elements in the lamp, make the lamp integrated, and improve the assembly efficiency.

[0092] In order to make the rotation of the light-transmitting piece 200 more stable, in some embodiments, the two sides of the installation piece 100 are respectively provided with a first swing angle part, the two sides of the light-transmitting piece 200 are respectively provided with a second swing angle part, and each first swing angle part is rotationally connected to a second swing angle part. For example, referring to Figure 4 A swing angle installation rotating hole 150 is arranged at each side of the installation piece 100, and a swing angle light-transmitting protrusion 221 is arranged at each side of the light-transmitting piece 200, and each swing angle light-transmitting protrusion 221 is rotationally arranged in a swing angle installation rotating hole 150.

[0093] In order to facilitate the assembly of the installation piece 100 and the light-transmitting piece 200, referring to Figure 2 and Figure 3In some embodiments, one side of the swing angle mounting through hole 150 is provided with a mounting through hole insertion port 151 extending to the edge of the mounting member 100; and / or, one side of the swing angle light transmission through hole is provided with a light transmission through hole insertion port extending to the edge of the light transmission member 200. Thus, the swing angle light transmission protrusion 221 is assembled into the swing angle mounting through hole 150 from the mounting through hole insertion port 151, and the swing angle mounting protrusion 110 is assembled into the swing angle light transmission through hole from the light transmission through hole insertion port, so as to realize the rotational connection of the mounting member 100 and the light transmission member 200.

[0094] In order to avoid the disconnection of the mounting member 100 and the light transmission member 200, see Figure 4 and Figure 8 In some embodiments, the width of the swing angle light transmission protrusion 221 away from the end of the light transmission member 200 is greater than the hole diameter of the swing angle mounting through hole 150; and / or, the width of the swing angle mounting protrusion 110 away from the end of the mounting member 100 is greater than the hole diameter of the swing angle light transmission through hole.

[0095] In order to facilitate the observation of the swing angle of the light transmission member 200, see Figure 11 In some embodiments, the light transmission member 200 is provided with a swing angle indication scale 222 for identifying the swing angle of the light transmission member 200. Wherein, the swing angle indication scale 222 is pre-marked on the light transmission member 200 according to the position of the light transmission member 200 at different swing angles relative to the mounting member 100. In order to facilitate the indication of the swing angle of the light transmission member 200, in some embodiments, according to the position of the light transmission member 200 at the preset swing angle, the swing angle indication scale 222 corresponding to the preset swing angle is provided on the light transmission member 200. Wherein, the preset swing angle is at least two, and the angle difference between the two different preset swing angles is different. In order to more reasonably indicate different swing angles, in some embodiments, the swing angle indication scale 222 is determined according to the initial swing angle and the preset swing angle difference. For example, the initial swing angle is selected as 5 degrees, and the preset swing angle difference is 5 degrees, so that the swing angle indication scale 222 is determined as 5 degrees, 10 degrees, 15 degrees, 20 degrees and 25 degrees. Wherein, the preset swing angle difference is the angle difference between the adjacent two preset swing angles. In order to facilitate the observation of the swing angle indication mark, in some embodiments, the swing angle indication scale 222 corresponding to each preset swing angle is provided on the same side of the light transmission member 200. In order to facilitate the swing angle indication scale 222 on the light transmission member 200, see Figure 11 In some embodiments, the swing angle indication scale 222 is provided along the rotation direction of the light transmission member 200 relative to the mounting member 100. Wherein, the swing angle of the light transmission member 200 can be determined by observing the relative position of the swing angle indication scale 222 and the mounting member 100. For example, the swing angle of the light transmission member 200 is determined by observing the swing angle indication scale 222 and the edge of the mounting member 100.

[0096] In order to more intuitively indicate the swing angle of the light transmission member 200, seeFigure 8 In some embodiments, the mount 100 is provided with a swing angle indicating portion 160, which is directed towards the swing angle indicating scale 222. In order to reduce the space occupied by the swing angle indicating portion 160, in some embodiments, the swing angle indicating portion 160 is arranged at the edge of the mount 100.

[0097] In order to fix the adjusted position of the light-transmitting member 200, in some embodiments, the mount 100 is provided with a first positioning portion, and the light-transmitting member 200 is provided with a second positioning portion, and the first positioning portion and the second positioning portion are movably connected. When the position of the light-transmitting member 200 is adjusted, the relative position of the mount 100 and the light-transmitting member 200 is fixed by connecting the first positioning portion and the second positioning portion. In order to reduce the combined space of the mount 100 and the light-transmitting member 200, in some embodiments, the first positioning portion is arranged at the side of the mount 100 which is directed towards the light-transmitting member 200, and the second positioning portion is arranged at the side of the light-transmitting member 200 which is directed towards the mount 100. Further, the first positioning portion is arranged at the side wall inside the ring of the mount 100, and the second positioning portion is arranged at the light-shielding portion of the light-transmitting member 200. In order to stabilize the relative position of the light-transmitting member 200 and the mount 100, in some embodiments, the second positioning portion is arranged along the rotation direction of the light-transmitting member 200 relative to the mount 100, and the first positioning portion is arranged at the side of the second positioning portion.

[0098] In order to movably connect the first positioning portion and the second positioning portion, in some embodiments, the first positioning portion and the second positioning portion are snap-connected. In order to fix the relative position of the light-transmitting member 200 and the mount 100 at different preset swing angles, in some embodiments, the second positioning portion includes at least two snap-connection portions, each of which is arranged according to the position of the light-transmitting member 200 at a preset swing angle, so that each snap-connection portion corresponds to a preset swing angle of the light-transmitting member 200. In order to facilitate the adjustment of the snap-connection position of the light-transmitting member 200 and the mount 100, in some embodiments, the material of the light-shielding portion 220 of the light-transmitting member 200 and the mount 100 includes PC plastic (Polycarbonate). In this way, the light-transmitting member 200 and the mount 100 are more wear-resistant and high-temperature-resistant, and the first positioning portion and the second positioning portion have higher resilience, which facilitates the snap-connection of the first positioning portion and the second positioning portion.

[0099] In order to facilitate the adjustment of the snap-connection position of the light-transmitting member 200 and the mount 100, referring to 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 is engaged with the positioning slots 223. In order to facilitate the sliding of the positioning protrusion 170 on the positioning slots 223, the surface of the positioning protrusion 170 is arc-shaped, and the surface of the positioning slots 223 is arc-shaped. In order to rotate the light-transmitting piece 200 more easily, in some embodiments, two sides of the first positioning part are provided with labor-saving notches 180, and the two sides of the first positioning part are separated from the main body of the mounting piece 100. Further, each labor-saving notch 180 extends along the rotation direction of the light-transmitting piece 200. Further, the labor-saving notches 180 are arc-shaped. Thus, since the two sides of the first positioning part are separated from the main body of the mounting piece 100, the positioning protrusion 170 is more easily pressed towards the positioning slots 223 or separated from the positioning slots 223.

[0100] Referring to Figure 11 In some embodiments, each positioning slot 223 is arranged along the rotation direction of the light-transmitting piece 200, and the angles of the corresponding swing angles of the two different positioning slots 223 are different. In order to adapt to the rotation of the light-transmitting piece 200, further, each positioning slot 223 is arranged on the outer side of the light-transmitting piece 200 in the circumferential direction. In order to fix the position of the light-transmitting piece 200 at each preset swing angle, further, each positioning slot 223 is determined according to the position of the light-transmitting piece 200 at each preset swing angle, and the positioning slot 223 and the preset swing angle correspond to each other, and each positioning slot 223 corresponds to a preset swing angle.

[0101] In order to reduce the rotation space of the light-transmitting piece 200, referring to Figure 6 , Figure 9 and Figure 10 In some embodiments, the light-transmitting piece 200 is provided with 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 piece 200. When the light-transmitting piece 200 rotates to one side of the rotation notch 224, since the light-transmitting piece 200 has the rotation notch 224, the rotation of the light-transmitting piece 200 is not limited by the lamp shell 20. At the same time, more space does not need to be reserved in the lamp shell 20 for the rotation of the light-transmitting piece 200, and the size of the lamp shell 20 can be reduced, so that the lamp is miniaturized. Further, the rotation notch 224 is arranged on the light-shielding part of the light-transmitting piece 200. In order to adapt to the rotation of the light-transmitting piece 200, in some embodiments, on the cross section of the second positioning part and the rotation notch 224, the cross section of the rotation notch 224 is fan-shaped. In order to avoid the lamp shell 20 from hindering the rotation of the light-transmitting piece 200, in some embodiments, the central angle of the rotation notch 224 is greater than or equal to the maximum value of each preset swing angle.

[0102] In some embodiments, referring to Figure 9 and Figure 10The lamp assembly 10 further comprises a reflector cup 300, which is configured to be connected to the lamp housing 20, and the reflector cup 300 is configured to reflect the light passing through the light-transmitting member 200 to the outside of the lamp housing 20. In some embodiments, the reflector cup 300 is arranged on the side close to the outside of the lamp housing 20, and the mounting member 100 and the light-transmitting member 200 are arranged on the side close to the inside of the lamp housing 20.

[0103] In order to facilitate the connection of the reflector cup 300 and the lamp housing 20, referring to Figure 3 and Figure 9 In some embodiments, the reflector cup 300 is configured to be clamped to the lamp housing 20. Since the light-transmitting member 200 is located on the inside of the lamp housing 20, in order to facilitate the adjustment of the light-transmitting member 200, in some embodiments, the reflector cup 300 is arranged in the shell groove 20A of the lamp housing 20, and the reflector cup 300 is clamped with the side wall of the shell groove 20A.

[0104] In order to reflect the light out of the lamp, referring to Figure 9 and Figure 10 In some embodiments, the reflector cup 300 is provided with a light reflection channel 310, one side of the light reflection channel 310 is directed to the light-transmitting member 200, and the other side of the light reflection channel 310 is directed to the outside of the lamp. In order to diffuse the light, further, the width of the light reflection channel 310 gradually increases from the side close to the light-transmitting member 200 to the side close to the outside of the lamp.

[0105] Referring to Figure 12 In one of the embodiments, when the light-transmitting member is 24 degrees, the light spot under the straight illumination of the lamp, i.e. the angle of repose is 0 degrees. Referring to Figure 13 When the light-transmitting member is 24 degrees, the wall washing light spot under the straight illumination of the lamp. As can be seen from Figure 12 and Figure 13 When the light-transmitting member is 24 degrees, the light spot is uniformly distributed under the straight illumination of the lamp.

[0106] Referring to Figure 14 In one of the embodiments, when the light-transmitting member is 24 degrees, the light spot at different positions when the light-transmitting member is 23.5 degrees under the straight illumination of the lamp. As can be seen from Figure 14 Within the range of the light beam angle, the light intensity is uniformly distributed, and the light intensity at the corresponding positions on both sides of the lamp is the same. The light intensity directly below the light-emitting body is the largest, reaching 8056.0 cd. Moreover, when the light-transmitting member is 24 degrees, the total collected power of the lamp under the straight illumination of the lamp is 1391.0 lm, the efficiency is 0.81582, and the light source is highly efficient.

[0107] Referring to Figure 15 In one of the embodiments, when the light-transmitting member is 24 degrees, the light spot at the wall washing position when the angle of repose of the light-transmitting member is 25 degrees. The light spot is uniformly distributed.

[0108] Referring toFigure 16 In one embodiment, when the light transmissive piece is 24 degrees, the light spot at different positions when the light transmissive piece is 25 degrees is shown in FIG. 6. As shown in FIG. 6, the light intensity of the light spot at different positions is uniform. Figure 16 The curve with the 25-degree line as the center line in FIG. 6 is the corresponding curve when the light transmissive piece is 24 degrees and the light transmissive piece is 25 degrees. As shown in FIG. 6, the light intensity is uniform within the beam angle. Figure 16 It can be seen that the light intensity is uniform within the beam angle. In addition, the light intensity at the positions on the two sides of the light fixture is the same. Figure 16 The curve with the 0-degree line as the center line in FIG. 6 is the corresponding curve of the light intensity of the light spot at different positions when the light transmissive piece is 24 degrees and the light fixture is directly illuminated.

[0109] Referring to FIG. 7, in one embodiment, the case of the light spot on the ground when the light transmissive piece is 36 degrees and the light fixture is directly illuminated. Figure 17 In one embodiment, the case of the light spot on the ground when the light transmissive piece is 36 degrees and the light fixture is directly illuminated. Figure 18 The case of the light spot on the wall when the light transmissive piece is 36 degrees and the light fixture is directly illuminated. As shown in FIG. 7, the light spot is uniformly distributed. Figure 17 and Figure 18 It can be seen that the light spot is uniformly distributed when the light transmissive piece is 36 degrees and the light fixture is directly illuminated.

[0110] Referring to FIG. 8, in one embodiment, the light intensity of the light spot at different positions when the light transmissive piece is 36 degrees and the light fixture is directly illuminated. Figure 19 It can be seen that the light intensity is uniform within the beam angle, and the light intensity at the positions on the two sides of the light fixture is the same. Figure 19 In FIG. 8, the two curves are the curves of the light intensity of the light fixture on the C0 / 180-degree plane and the C90 / 270-degree plane, respectively. It can be seen that the two curves are basically coincident, indicating that the light intensity distribution of the light fixture at different positions is uniform when the light transmissive piece is 36 degrees and the light fixture is directly illuminated. Figure 19 Referring to FIG. 9, in one embodiment, the light spot on the wall when the light transmissive piece is 36 degrees and the light transmissive piece is 25 degrees is shown in FIG. 9. As shown in FIG. 9, the light spot is uniformly distributed.

[0111] Figure 20 Referring to FIG. 10, in one embodiment, the light intensity of the light spot at different positions when the light transmissive piece is 36 degrees and the light transmissive piece is 25 degrees is shown in FIG. 10. As shown in FIG. 10, the light intensity of the light spot at different positions is uniform.

[0112] The curve deviating from the 0-degree line in FIG. 10 is the corresponding curve when the light transmissive piece is 24 degrees and the light transmissive piece is 25 degrees. As shown in FIG. 10, the light intensity is relatively uniform on the two sides of the light fixture within the beam angle. Figure 21 It can be seen that the light intensity is uniform within the beam angle, and the light intensity at the positions on the two sides of the light fixture is the same. Figure 21 In FIG. 10, the curve with the 0-degree line as the center line is the corresponding curve of the light intensity of the light spot at different positions when the light transmissive piece is 36 degrees and the light fixture is directly illuminated. Figure 21 Figure 21 It can be seen that the light intensity is uniform within the beam angle. In addition, the light intensity at the positions on the two sides of the light fixture is the same.

[0113] Referring to FIG. 11, in one embodiment, the light intensity of the light spot at different positions when the light transmissive piece is 36 degrees and the light transmissive piece is 25 degrees is shown in FIG. 11. As shown in FIG. 11, the light intensity of the light spot at different positions is uniform. Figure 22 ​​In one of the embodiments, the case of the light spot on the floor under the direct illumination of the lamp with the light transmissive piece of 50 degrees. See Figure 23 The case of the light spot on the wall under the direct illumination of the lamp with the light transmissive piece of 50 degrees. From Figure 22 and Figure 23 It can be seen that the light spot is uniformly distributed under the direct illumination of the lamp with the light transmissive piece of 50 degrees.

[0114] See Figure 24 In one of the embodiments, the case of the light intensity of the light spot at different positions under the direct illumination of the lamp with the light transmissive piece of 50 degrees. From Figure 24 It can be seen that the light intensity is uniformly distributed within the beam angle, and the light intensity at the corresponding positions on both sides of the lamp is substantially the same, and the maximum light intensity is 2095.7 cd. Figure 24 In the figure, the two curves are the curves of the light intensity of the lamp at C0 / 180 degrees and C90 / 270 degrees, respectively. It can be seen that the two curves substantially coincide, indicating that the light intensity distribution of the lamp at different directions is uniform under the direct illumination of the lamp with the light transmissive piece of 50 degrees.

[0115] See Figure 25 In one of the embodiments, the case of the light spot on the wall when the tilt angle of the light transmissive piece is 15 degrees under the direct illumination of the lamp with the light transmissive piece of 50 degrees. The light spot is uniformly distributed.

[0116] See Figure 26 In one of the embodiments, the case of the light spot on the wall when the tilt angle of the light transmissive piece is 25 degrees under the direct illumination of the lamp with the light transmissive piece of 50 degrees. The light spot is uniformly distributed. The light spot distribution is more uniform when the tilt angle is 25 degrees than when the tilt angle is 15 degrees.

[0117] See Figure 27 In one of the embodiments, the case of the light intensity of the light spot at different positions when the tilt angle of the light transmissive piece is 15 degrees under the direct illumination of the lamp with the light transmissive piece of 50 degrees, that is, Figure 27 In the figure, the curve deviating from the 0-degree line is the curve corresponding to the case when the tilt angle of the light transmissive piece is 15 degrees under the direct illumination of the lamp with the light transmissive piece of 50 degrees. From Figure 27 It can be seen that the light intensity is uniformly distributed within the beam angle, and the light intensity at the corresponding positions on both sides of the lamp is substantially the same, and the maximum light intensity is 1997.9 cd, and the light efficiency is 0.79522. Among them, Figure 27 In the figure, the curve with the 0-degree line as the center line is the curve corresponding to the light intensity of the light spot at different positions under the direct illumination of the lamp with the light transmissive piece of 50 degrees.

[0118] See Figure 28 In one of the embodiments, the case of the light intensity of the light spot at different positions when the tilt angle of the light transmissive piece is 25 degrees under the direct illumination of the lamp with the light transmissive piece of 50 degrees, that 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.

[0119] 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.

[0120] 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.

[0121] To adjust the beam angle, see [link / reference]. Figure 31 and Figure 32In an embodiment, the lamp assembly 10 further comprises a lamp housing 20, the lamp housing 20 further comprises an inner housing 201 and an outer housing 202, the inner housing 201 is provided with a housing slot 20A, the outer housing 202 is provided with a sliding slot 2021, the inner housing 201 is slidingly arranged in the sliding slot 2021, the inner housing 201 is movably connected with the outer housing 202, the inner housing 201 is provided with a light hole 2011, the light hole 2011 is communicated with the housing slot 20A, the outer housing 202 is provided with a light block 2022, the light block 2022 is movably arranged in the light hole 2011 and the housing slot 20A, and the light block 2022 is used for mounting the light emitter 30. By sliding the inner housing 201 in the sliding slot 2021, the position of the light transmission piece is adjusted, and then the distance between the light transmission piece 200 and the light emitter 30 is changed, the zooming is realized, and then the angle of the light beam angle is adjusted, so that the light spot is more uniform. Moreover, the adjustment of the angle of the light beam angle can be realized without disassembling the lamp and replacing the light transmission piece 200. The mounting piece 100 and the light transmission piece 200 are arranged in the housing slot 20A of the inner housing 201. In an embodiment, after the position of the inner housing 201 in the sliding slot 2021 is adjusted, the inner housing 201 and the outer housing 202 can be fixed by clamping and screwing, so as to fix the position of the inner housing 201 in the sliding slot 2021, thereby selecting the corresponding angle of the light beam angle. It should be understood that the angle of the light beam angle can be adjusted by the distance between the light emitter 30 and the light transmission piece 200, so when the inner housing 201 slides to different positions in the sliding slot 2021, the corresponding angle of the light beam angle is different, thereby the adjustment of the angle of the light beam angle can be realized.

[0122] In order to realize the movable connection of the inner shell 201 and the outer shell 202, in an embodiment, the side wall of the sliding groove 2021 is provided with an outer shell protrusion 2023, the side wall of the inner shell 201 is provided with an inner shell groove 2012, the outer shell protrusion 2023 is clamped in the inner shell groove 2012, and the outer shell protrusion 2023 and / or the inner shell groove 2012 are at least two, which are arranged along the direction of the light. Among them, the outer shell protrusion 2023 can be one, and the inner shell groove 2012 can be two or more; or the outer shell protrusion 2023 can be two or more, and the inner shell groove 2012 can be one; or the outer shell protrusion 2023 and the inner shell groove 2012 can have two or more respectively. By clamping the outer shell protrusion 2023 in different inner shell grooves 2012 or setting different outer shell protrusions 2023 in the inner shell groove 2012, the position of the inner shell 201 relative to the outer shell 202 is changed, and the distance between the light-transmitting piece 200 and the light-emitting body 30 is changed, thereby realizing zooming and adjusting the angle of the light beam. In order to realize the switching between different angles of the light beam, in an embodiment, the angles of the light beams corresponding to the different two inner shell grooves 2012 on the inner shell 201 are different; or the angles of the light beams corresponding to the different two outer shell protrusions 2023 on the outer shell 202 are different; or the angles of the light beams corresponding to the clamping combinations between the outer shell protrusions 2023 on the outer shell 202 and the inner shell grooves 2012 on the inner shell 201 are different. When the outer shell protrusion 2023 is one and the inner shell groove 2012 is two or more, the angles of the light beams corresponding to the different two inner shell grooves 2012 are different. When the inner shell groove 2012 is one and the outer shell protrusion 2023 is two or more, the angles of the light beams corresponding to the different two outer shell protrusions 2023 are different. When the outer shell protrusion 2023 and the inner shell groove 2012 are two or more respectively, by the various clamping combinations between the outer shell protrusion 2023 and the inner shell groove 2012, the relative position of the outer shell 202 and the inner shell 201 is changed, thereby realizing zooming and adjusting the angle of the light beam.

[0123] To achieve the movable connection of 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, the side wall of the inner shell 201 is provided with an inner shell protrusion, the inner shell protrusion is clamped in the outer shell groove, and the outer shell groove and / or the inner shell protrusion is at least two, each outer shell groove and / or each inner shell protrusion is arranged along the direction of the light. By clamping the inner shell protrusion in different outer shell grooves or opening different inner shell protrusions in the outer shell groove, the position of the inner shell 201 relative to the outer shell 202 is changed, and the distance between the light-transmitting piece 200 and the light emitter 30 is changed, thereby achieving zooming and adjusting the angle of the light beam. To achieve switching between different angles of the light beam, in one embodiment, the angles of the light beam corresponding to the different inner shell protrusions on the inner shell 201 are different; or, the angles of the light beam corresponding to the different outer shell grooves on the outer shell 202 are different; or, the angles of the light beam corresponding to the clamping combination between each outer shell groove on the outer shell 202 and each inner shell protrusion on the inner shell 201 are different.

[0124] To achieve switching between two angles of the light beam, see Figure 31 and Figure 32 , in one embodiment, the side wall of the sliding groove 2021 is provided with an outer shell protrusion 2023, the side wall of the inner shell 201 is provided with two inner shell grooves 2012, and the two inner shell grooves 2012 are arranged along the direction of the light. One inner shell groove 2012 corresponds to a first preset angle of the light beam, and the other inner shell groove 2012 corresponds to a second preset angle of the light beam. Among them, the inner shell groove 2012 close to the slot opening of the shell groove corresponds to a larger angle of the light beam than the inner shell groove 2012 close to the slot bottom of the shell groove. See Figure 31 and Figure 32 , in one embodiment, the angle of the light beam corresponding to the inner shell groove 2012 close to the slot opening of the shell groove is 36 degrees, and the angle of the light beam corresponding to the inner shell groove 2012 close to the slot bottom of the shell groove is 24 degrees. See Figure 33 When the outer shell protrusion 2023 is clamped in the inner shell groove 2012 close to the slot opening of the shell groove, the distance between the light emitter and the light-transmitting piece is smaller, the angle of the light beam is larger, and the angle of the light beam is 36 degrees. See Figure 34 When the outer shell protrusion 2023 is clamped in the inner shell groove 2012 close to the slot bottom of the shell groove, the distance between the light emitter and the light-transmitting piece is larger, the angle of the light beam is smaller, and the angle of the light beam is 24 degrees. See Figure 35 and Figure 36 , the light beams corresponding to the angles of 36 degrees and 24 degrees of the light beam are respectively 36 degrees and 24 degrees. The transition between the two light spots is uniform. See Figure 37 and Figure 38 When the angles of the light beams are 36 degrees and 24 degrees respectively, the light intensity corresponding to the same position is smaller, avoiding the sudden change of the light intensity and causing the discomfort of the human eye.

[0125] Corresponding to the foregoing application function implementation method embodiments, the application further provides a lamp and corresponding embodiments.

[0126] Referring to Figure 2 , Figure 9 and Figure 10 , a lamp of an embodiment includes the lamp assembly of any of the foregoing embodiments.

[0127] In order to install the light emitter in the shell groove, in some embodiments, a light source support is connected to the bottom of the shell groove, and the light source support is used to install the light emitter. The light source support can be installed on the lamp shell by locking screws. In order to adjust the angle of the light beam angle, referring to Figure 31 and Figure 32 , in an embodiment, the light source support is arranged on the light placing block.

[0128] In order to dissipate heat for the lamp, referring to Figure 2 , in some embodiments, the lamp further includes a heat sink 50 arranged on the lamp shell 20.

[0129] In some embodiments, the light emitter includes an LED lamp, a halogen lamp, and an incandescent lamp.

[0130] Compared with the prior art, the application has at least the following advantages:

[0131] 1. By rotating the mounting member, the mounting member and the light-transmitting member are rotated relative to the lamp shell. By rotating the light-transmitting member, the light-transmitting member is rotated relative to the mounting member. The rotation direction of the light-transmitting member driven by the rotation of the mounting member is different from the rotation direction of the light-transmitting member itself. Therefore, the light-transmitting member can be independently rotated in two directions, and the light distribution adjustment in the horizontal and vertical directions can be achieved. The light-transmitting member can achieve 360-degree light distribution adjustment in the horizontal plane, so as to adjust the tangential light angle relative to the wall. The light-transmitting member can achieve 0-35-degree light distribution adjustment in the vertical plane.

[0132] 2. Since the mounting member and the light-transmitting member are installed in the shell groove of the lamp shell, the mounting member and the light-transmitting member do not need to be moved or reinstalled when they are rotated. The rotation of the mounting member and the light-transmitting member does not need to be limited by objects outside the lamp shell. The objects outside the lamp shell cannot hinder the rotation of the mounting member and the light-transmitting member, thereby reducing the space for installing the lamp.

[0133] 3. The lamp assembly is installed in the shell groove of the lamp shell. The light distribution adjustment function of the lamp is not sacrificed, and the lamp does not need to rely on connecting elements. The lamp is connected by the structure of the light-transmitting member and the mounting member itself, so that the appearance of the lamp is simple and clean. The assembly of the lamp is more convenient, and the assembly efficiency is improved.

[0134] 4. The light distribution adjustment from 0 degrees to 35 degrees is achieved by adjusting the degree of the light-transmitting member.

[0135] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are within the scope of protection of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
