[0025] In use, existing streetlights typically illuminate only in a single direction, resulting in a limited lighting coverage area that cannot meet the needs of multi-directional illumination. Furthermore, existing streetlights only have two luminous surfaces: the bottom and the top, further reducing the illuminated area.

[0026] This utility model proposes a lamp 100.

[0027] Please see Figures 1 to 9 As shown, in one embodiment of this utility model, the lamp 100 includes a column 10, a lamp head 20, and a connecting component 30; the connecting component 30 connects the lamp head 20 and the column 10, and the lamp head 20 can be oscillated relative to the column 10 about a first axis through the connecting component 30, the first axis extending along a first direction; and / or, the lamp head 20 can be oscillated relative to the column 10 about a second axis through the connecting component 30, the second axis extending along a second direction, the first direction intersecting the second direction.

[0028] The lamp 100 of this utility model may further include a base 40. When the lamp 100 is in use, the base 40 may be located at the bottom end of the column 10 to support the entire lamp 100. The lamp head 20 is connected to the top of the column 10 via a connecting component 30. The lamp 100 may be a street lamp or floor lamp placed indoors. The first direction may be left-right, and the second direction may be perpendicular to the first direction. When the lamp head 20 is oscillating relative to the column 10 around the first axis via the connecting component 30, the lamp head 20 may also oscillate around a horizontal axis extending left-right. The lamp head 20 may oscillate between multiple angles, including upward, downward, forward, and backward, allowing the lamp 100 to have multiple illumination angles. When the lamp head 20 is adjusted by swinging relative to the column 10 around the second axis via the connecting assembly 30, the light-emitting surface 20b of the lamp 100 can rotate in the same plane. When the lamp head 20 is illuminating in the same direction, different parts of the lamp head 20 can be rotated to different positions, so that different positions in the same direction can be illuminated, thereby enabling the lamp 100 to have a larger illumination coverage.

[0029] When the lamp head 20 can be adjusted by swinging around a first axis, the connecting assembly 30 may include a first rotating shaft extending along a first direction, one end of which is disposed on the lamp head 20, and the other end of a second rotating shaft is rotatably connected to the column 10. Contact damping is provided between the first rotating shaft and the column 10, allowing the lamp head 20 to hover when rotated to any angle. When the lamp head 20 can be adjusted by swinging around a second axis, the connecting assembly 30 may include a second rotating shaft extending along a second direction, one end of which is disposed on the lamp head 20, and the other end of which is disposed on the column 10. Contact damping is provided between the second rotating shaft and the column 10, allowing the lamp head 20 to hover when rotated to any angle. When the lamp head 20 can rotate around the first axis and the second axis simultaneously, the connecting component 30 may include a first rotating shaft, a connecting rod and a second rotating shaft. The connecting rod is connected to the column 10 through the first rotating shaft and to the lamp head 20 through the second rotating shaft. One end of the connecting component 30 can realize the rotation of the lamp head 20 around the first axis, and the other end of the connecting component 30 can be set to allow the lamp head 20 to rotate around the second axis.

[0030] The technical solution of this utility model is to set the lamp 100 including a column 10, a lamp head 20 and a connecting component 30. The lamp head 20 is connected to the column 10 through the connecting component 30, and the lamp head 20 can swing relative to the column 10 around a first axis through the connecting component 30, and / or the lamp head 20 can swing relative to the column 10 around a second axis through the connecting component 30, so that the lamp head 20 can swing relative to the column 10 at multiple angles and directions. The lamp head 20 can illuminate in different directions and at different positions in different directions, so that the lamp 100 has a larger lighting coverage.

[0031] The structure of the connecting component 30 is described below, such as... Figure 1 , Figure 2 , Figure 3 As shown, in one embodiment, the connecting component 30 includes a crossbar 31 and a first sub-connecting component 32. The lamp head 20 is disposed at one end of the crossbar 31, and the other end of the crossbar 31 is rotatably connected to the column 10 through the first sub-connecting component 32. The crossbar 31 can rotate relative to the column 10 around the first axis.

[0032] In one embodiment, when the lamp 100 is in use, one end of the first sub-connecting component 32 can be fixed to the upper end of the column 10, and the side end of the first sub-connecting component 32 can be rotatably connected to the crossbar 31. When the lamp head 20 is located at one end of the crossbar 31, and the crossbar 31 can rotate relative to the column 10 around the first axis, the rotation of the crossbar 31 can drive the lamp head 20 to rotate around the first axis, thereby achieving angle adjustment of the lamp head 20 around the first axis. Alternatively, in another embodiment, one side end of the first connecting component 30 can be rotatably connected to one side of the column 10, and the other side end of the first connecting component 30 can be fixedly connected to the crossbar 31, which can also achieve rotation of the lamp head 20 relative to the column 10 around the first axis. No specific limitation is made here.

[0033] The specific structure of the first sub-connection component 32 is described below, such as... Figure 2 , Figure 3 , Figure 7 As shown, in one embodiment, the first sub-connection assembly 32 includes a first base 321 and a first rotating member 322. The first rotating member 322 is rotatably disposed on the first base 321 about a first axis. One of the first base 321 and the first rotating member 322 is disposed on the column 10, and the other is disposed on the crossbar 31.

[0034] The first base 321 can be mounted on the column 10, and the first rotating member 322 can be rotatably connected to the first base 321 and connected to the crossbar 31. The first rotating member 322 may include a first nut 3221 and a first screw 3222. The first sub-connecting assembly 32 may also include a first fixing plate 324. The first base 321 may include a base body 3212 and a second fixing plate 3211. The base body 3212 is fixed to the top of the column 10, and the second fixing plate 3211 is fixed inside the base body 3212. The second fixing plate 3211 may have a through hole, the diameter of which may be larger than the diameter of the first screw 3222's shank, allowing the shank of the first screw 3222 to pass through. The diameter of the through hole is smaller than the diameter of the nut portion of the first screw 3222. The nut of the first screw 3222 is used for limiting the position. The second fixing plate 3211 can be fixed to the inner wall of the crossbar 31. The second fixing plate 3211 can be provided with a through hole for the rod of the first screw 3222 to pass through. The first nut 3221 is threadedly connected to the first screw 3222 and abuts against the second fixing plate 3211 through the first elastic washer 3223, which fastens the first rotating member 322 to the first fixing plate 324, thereby fastening the first rotating member 322 to the crossbar 31. The first rotating member 322 can be rotated through the through hole on the first screw 3222 and the second fixing plate 3211 to achieve the rotational engagement between the first rotating member 322 and the base.

[0035] In this way, the crossbar 31 can be rotatably connected to the first base 321 through the assembly relationship between the first screw 3222 and the first nut 3221. This improves the portability of the first crossbar 31, which can be rotatably assembled onto the column 10 around the first axis.

[0036] The structure of the first sub-connection component 32 will be further described below, such as... Figure 2 , Figure 3 , Figure 7 As shown, in one embodiment, the first sub-connecting component 32 further includes a first sub-limiting component 323, which is disposed between the first rotating member 322 and the first base 321. The first sub-limiting component 323 is used to limit the rotation angle of the first rotating member 322 about the first axis.

[0037] Thus, by limiting the rotation angle of the first rotating member 322 around the first axis by the first sub-limiting component 323, the rotation angle of the lamp head 20 relative to the column 10 around the first axis can be limited, preventing the lamp head 20 from rotating too much around the first axis and interfering with the column 10, or preventing the internal wiring of the crossbar 31 from being damaged when the crossbar 31 rotates too much. For example, when the crossbar 31 rotates 720 degrees around the first axis, the wiring connected to the lamp head 20 inside the column 10 may become tangled and damaged.

[0038] The structure of the first sub-limiting component 323 will be described below, such as... Figure 2 , Figure 3 , Figure 7 As shown, in one embodiment, the first base 321 is disposed on the column 10, and the first rotating member 322 is disposed on the crossbar 31; The first sub-limiting component 323 includes a first limiting member 3231 disposed on the first base 321 and a first limiting mating member 3232 disposed on the first rotating member 322. The first limiting member 3231 has a first rotating groove 32311 for the first limiting mating member 3232 to be inserted and rotated. The first rotating groove 32311 has two opposing limiting walls 32312. The first limiting mating member 3232 has a limiting rib 32321. The limiting rib 32321 is used to swing back and forth between the two limiting walls 32312 to limit the rotation angle of the first rotating member 322.

[0039] The column 10 may include a column body 11 and a column connector 12. The first base 321 is inserted and fixed to the column connector 12, and the column connector 12 is inserted and fixed to the column body 11. The first limiting member 3231 may be disposed on the first base 321 and connected and fixed to the base body 3212 and the second fixing piece 3211 respectively. The first limiting member 3231 may have a through hole for the screw to pass through. The first rotating groove 32311 may be disposed on the side of the first limiting member 3231 facing the crossbar 31 and circumferentially disposed in the through hole. The first limiting fitting 3232 can be sleeved on the screw and inserted into the first rotating groove 32311. The first limiting fitting 3232 can be limited in the first rotating groove 32311 by the second fixing piece 3211. The limiting rib 32321 can protrude radially towards the first limiting fitting 3232. When the first limiting fitting 3232 rotates with the screw and rotates in the first rotating groove 32311, the limiting rib 32321 swings around the first axis and swings back and forth between the two limiting walls 32312. The first limiting fitting 3232 cannot complete a 360-degree full-angle rotation, thereby limiting the rotation angle of the first rotating part 322, and further limiting the swing angle of the lamp head 20 around the first axis, preventing damage to the internal circuit of the lamp 100.

[0040] When the lamp 100 can rotate relative to the column about the second axis, the connecting assembly 30 may further include a second sub-connecting assembly 33. The structure of the second sub-connecting assembly 33 is further described below, such as... Figure 2 , Figure 4 As shown, in one embodiment, the connecting component 30 further includes a second sub-connecting component 33, and the end of the crossbar 31 away from the first sub-connecting component 32 is rotatably connected to the lamp head 20 through the second sub-connecting component 33. The lamp head 20 can rotate relative to the crossbar 31 about a second axis.

[0041] The second direction can be a direction perpendicular to the first direction. For example, the second direction can be the direction of any straight line extending from a plane perpendicular to the first axis. With the orthocenter of the first axis in the plane as the base point, the second axis can be any straight line passing through the base point in the plane.

[0042] Therefore, when the crossbar 31 is rotatably connected to the column 10 along the first axis via the first sub-connecting assembly 32, and the second sub-connecting assembly 33 is rotatably connected to the lamp head 20 and the crossbar 31 along the second axis, the lamp head 20 located on the crossbar 31 can have a larger adjustment range, can cover a wider lighting range, and thus improve the lighting range of the lamp 100.

[0043] like Figure 2 , Figure 4 , Figure 9 As shown, in one embodiment, the second sub-connection assembly 33 includes a second base 331 and a second rotating member 332. The second rotating member 332 is rotatably disposed on the second base 331 about a second axis. One of the second base 331 and the second rotating member 332 is disposed on the crossbar 31, and the other is disposed on the lamp head 20.

[0044] The second base 331 can be disposed on the side of the crossbar 31 facing the lamp head 20, and the second rotating component 332 can be disposed on the lamp head 20. The second rotating component 332 can include a second nut 3321 and a second screw 3322. The second nut 3321 can be disposed in the inner cavity of the crossbar 31, and the second screw 3322 can pass through the through hole opened on the second base 331 and be threadedly connected to the second nut 3321, so that the second nut 3321 and the second screw 3322 can form a fixed whole with the lamp head 20 and rotate relative to the second base 331 around the second axis. Since the second base 331 is fixed relative to the crossbar 31, the lamp head 20 can rotate relative to the crossbar 31 around the second axis.

[0045] like Figure 2 , Figure 4 , Figure 9 As shown, in one embodiment, the second sub-connecting component 33 further includes a second sub-limiting component 333, which is disposed between the second base 331 and the second rotating member 332. The second sub-limiting component 333 is used to limit the rotation angle of the second rotating member 332 about the second axis.

[0046] It is understandable that, similar to the first sub-connecting component 32, in order to prevent the lamp head 20 from rotating too much when it is rotatably connected to the crossbar 31 through the second sub-connecting component 33, which could cause the internal wires to become knotted and damaged, the second sub-connecting component 33 is provided to include a second sub-limiting component 333. This prevents the second rotating component 332 from rotating too much around the second axis, which could damage the wires connected to the lamp head 20. At the same time, it can also prevent the lamp head 20 from rotating too much and interfering with the column 10.

[0047] The structure of the second sub-limiting component 333 will be further described below. For example... Figure 4 , Figure 8 , Figure 9 As shown, in one embodiment, the second base 331 is disposed on the crossbar 31, and the second rotating member 332 is disposed on the lamp head 20; The second sub-limiting component 333 includes a second limiting member 3331 and a second limiting mating member 3332. The second limiting member 3331 is disposed on the second base 331 and has two spaced-apart protrusions 3331a. The second rotating member 332 has a second rotating groove 332a for the second limiting member 3331 to be inserted into. The second limiting mating member 3332 is disposed in the second rotating groove 332a and is used to reciprocate between the two protrusions 3331a to limit the rotation angle of the second rotating member 332.

[0048] The second rotating component may further include a fixed base. A second screw 3322 is disposed on the fixed base and passes through the fixed base to be threadedly fastened to a second nut 3321. The second screw 3322 is fixed on the fixed base, which is connected and fixed to the lamp holder 20, so that the second rotating component 332, composed of the second screw 3322, the second nut 3321, and the fixed base, is fixedly connected to the lamp holder 20. The fixed base may have a second rotating groove 332a facing the crossbar 31. The second limiting fitting 3332 may be a rib located in the second rotating groove 332a. The second limiting member 3331 may be a washer that fits and is fixed to the second base 331. The washer has two spaced protruding ridges 3331a, which may be the two protruding ends of the ribs located on the outer periphery of the second limiting member. The second limiting member 3331 is housed within the second rotating groove 332a of the second rotating member 332. When the second limiting member 3332 rotates, the second limiting member 3331 remains relatively fixed, allowing the second limiting member 3332 within the second rotating groove 332a to reciprocate in the gap between the two protrusions 3331a, thereby limiting the swing angle of the second limiting member 3332. This limits the swing angle of the lamp head 20 relative to the crossbar 31 around the second axis with the second rotating member 332, preventing damage from excessive rotation of the lamp head 20.

[0049] Additionally, the second sub-connecting assembly 33 may also include a second elastic washer 3323, which may be disposed within the inner cavity of the crossbar 31. After the screw passes through the inner cavity of the crossbar 31, it passes through the second elastic washer 3323 and is connected and fixed to the second nut 3321. The crossbar 31 may also have a top cover 311, which has an opening for the second nut 3321 to be inserted into the inner cavity of the crossbar 31, and the top cover 311 is used to cover the opening.

[0050] like Figure 1 , Figure 2 As shown, in one embodiment, the lamp head 20 has a plurality of light-emitting parts 20a connected in sequence. Each light-emitting part 20a has a first surface 21a and a second surface 21b arranged opposite to each other. The included angle between adjacent light-emitting parts 20a is an obtuse angle. The first surface 21a and / or the second surface 21b are configured as light-emitting surfaces 20b.

[0051] It is understandable that when the included angle between adjacent light-emitting parts 20a is an obtuse angle, and the first surface 21a of the light-emitting part 20a is configured as a light-emitting surface 20b, multiple light-emitting parts 20a can form a diffused illumination range when emitting light through their respective first surfaces 21a, thus making the illumination coverage of the lamp head wider. When both the first surface 21a and the second surface 21b are configured as light-emitting surfaces 20b, not only can the coverage of the lamp head 20 illuminating in a single direction be increased through multiple first surfaces 21a, but the illumination coverage of the lamp head 20 can also be further increased through the second surface 21b, enabling the lamp head 20 to illuminate in two opposite directions.

[0052] like Figure 1 , Figure 2 As shown, in one embodiment, the plurality of light-emitting parts 20a include a first light-emitting part 21 and two second light-emitting parts 22. The two second light-emitting parts 22 are respectively disposed on opposite sides of the first light-emitting part 21. The first surface 21a of the first light-emitting part 21 is configured as a light-emitting surface 20b. The first surface 21a and / or the second surface 21b of each second light-emitting part 22 is configured as a light-emitting surface 20b.

[0053] The second surface of the first light-emitting part is connected to the crossbar via a second sub-connecting assembly. The lamp head is connected to the column via the connecting assembly 30. It is understood that since the lamp head 20 needs to be connected to the column 10 via the connecting assembly 30, the second surface 21b of the first light-emitting part 21 can be connected to the crossbar 31 via the second sub-connecting assembly 33. The first surface 21a of the first light-emitting part 21 can be configured as the light-emitting surface 20b, while the two second light-emitting parts 22 are respectively disposed on opposite sides of the first light-emitting part 21, without needing to be connected to the column 10 via the connecting assembly 30. Therefore, not only can the first surface 21a of the second light-emitting part 22 be configured as the light-emitting surface 20b, but the second surface 21b of the second light-emitting part 22 can also be configured as the light-emitting surface 20b. When the second surface 21b of the second light-emitting part 22 is configured as the light-emitting surface 20b, the lamp head 20 can emit light in two opposite directions, resulting in a larger illumination coverage. When the first surface 21a of the second light-emitting part 22 is configured as the light-emitting surface 20b, the lamp head 20 can emit light towards the side closer to the first surface 21a. Since adjacent light-emitting parts 20a are arranged at an obtuse angle, the illumination coverage towards the first surface 21a can be increased. When both the first surface 21a and the second surface 21b of the second light-emitting part 22 are light-emitting surfaces 20b, both opposite directions of the lamp head can have a large illumination coverage, thereby further improving the illumination coverage of the lamp 100. Specifically, the plurality of light-emitting parts 20a also include two third light-emitting parts, which are respectively connected to the side of the two second light-emitting parts 22 away from the first light-emitting part.

[0054] In addition, to further enhance the lighting coverage of the lamp 100, a light-emitting strip can be provided around the lamp head 20 so that the lamp head 20 can emit light in a circular manner, thereby further enhancing the lighting coverage of the lamp 100.

[0055] like Figure 2 , Figure 5 As shown, in one embodiment, each of the second light-emitting parts 22 includes a metal plate 221 and at least one lamp plate 222. The lamp plate 222 for emitting light toward the first surface 21a is provided on the side of the metal plate 221 near the first surface 21a, and / or, the lamp plate 222 for emitting light toward the second surface 21b is provided on the side of the metal plate 221 near the second surface 21b.

[0056] Each light-emitting part 20a may include a lamp housing. The metal plate 221 and lamp plate 222 of the second light-emitting part 22 are disposed within the corresponding lamp housing. The first surface 21a and the second surface 21b may be two surfaces of the lamp housing that are opposite to each other. It is understood that when the lamp plate 222 emits light, it will generate heat. To prevent the lamp plate 222 from overheating and shortening its lifespan, the metal plate 221 is provided so that the lamp plate 222 is in contact with the metal plate 221. The heat generated by the lamp plate 222 during operation can be quickly dissipated through the metal plate 221. Furthermore, when the lamp plate 222 is in contact with the metal plate 221, the metal plate 221 can support the lamp plate 222, preventing it from sagging or deforming.

[0057] Each second light-emitting part 22 may be provided with at least one lamp plate 222. When only one lamp plate 222 is provided, the lamp plate 222 may be located on the side of the metal plate 221 near the first surface 21a, so that the lamp plate 222 emits light toward the first surface 21a, in which case the first surface 21a is the light-emitting surface 20b. Alternatively, the lamp plate 222 may be located on the side of the metal plate 221 near the second surface 21b, so that the lamp plate 222 emits light toward the second surface 21b, in which case the second surface 21b is the light-emitting surface 20b. The first surface 21a and the second surface 21b may be configured as light-transmitting surfaces to facilitate the light emitted by the lamp plate 222 to pass through.

[0058] When each second light-emitting part 22 is provided with two sets of lamp plates 222, the two sets of lamp plates 222 can be respectively located on the side of the metal plate 221 near the first surface 21a and the side of the second surface 21b, so that the two sets of lamp plates 222 are arranged back to back. One set of lamp plates 222 emits light towards the first surface 21a, and the other set of lamp plates 222 emits light towards the second surface 21b. On the one hand, it can save the internal space of the light-emitting part 20a. On the other hand, the metal plate 221 can be attached to the two sets of lamp plates 222 respectively to quickly conduct the heat generated by the two sets of lamp plates 222 during operation, which is convenient for the second light-emitting part 22 to dissipate heat during operation. Furthermore, the metal plate 221 sandwiched between the two lamp plates 222 can provide support for the lamp plates 222, so that the second light-emitting part 22 has sufficient structural strength.

[0059] In addition, when the second light-emitting part 22 is provided with three light panels 222, another light panel 222 can be attached to the periphery of the metal plate 221, that is, the third light-emitting part 20a is set as a light strip and attached to the periphery of the metal plate 221 away from the first light-emitting part 21, so that the second light-emitting part 22 has a wider illumination range.

[0060] Optionally, the metal plate 221 can be configured as an aluminum profile metal plate 221. Aluminum has a high thermal conductivity, which is more conducive to heat dissipation of the lamp holder 20. The metal plate 221 can be equipped with reinforcing ribs to improve the overall structural strength of the metal plate 221.

[0061] Alternatively, a metal plate 221 can be provided inside the first light-emitting part 21 to dissipate heat from the lamp plate 222 inside the first light-emitting part 21 and to support the lamp plate 222. The relevant settings will not be described in detail here.

[0062] like Figure 2 As shown, in one embodiment, the lamp head 20 further includes an auxiliary light-emitting part 23, which is provided on the light-emitting part 20a or between two adjacent light-emitting parts 20a.

[0063] The auxiliary light-emitting part 23 can be disposed on the light-emitting part 20a. For example, the auxiliary light-emitting part 23 can be disposed inside the lamp housing, or it can be sandwiched between two adjacent light-emitting parts 20a. The auxiliary light-emitting part 23 can be used to emit infrared light, and the wavelength of the emitted infrared light can be between 760nm and 1.5μm. It can be understood that natural sunlight contains not only visible light but also a suitable amount of near-infrared light. The human visual system is more adapted to the combination of visible light and near-infrared light. Near-infrared light has a certain degree of penetrability and can act on the ciliary muscle of the eye, helping the ciliary muscle to reduce continuous contraction during prolonged viewing and reducing problems such as eye strain, dry eyes, and blurred vision caused by ciliary muscle fatigue.

[0064] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
