[0022] In use, existing streetlights typically illuminate only one direction, resulting in a limited coverage area that cannot meet the lighting needs of multiple directions.

[0023] This utility model proposes a lamp.

[0024] Please see Figures 1 to 5 In one embodiment of the present invention, the lamp 100 has a lamp head 20, which 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. Two adjacent light-emitting parts 20a are arranged at an obtuse angle. The first surface 21a and / or the second surface 21b are configured as light-emitting surfaces 20b.

[0025] The lamp 100 of this utility model may further include a column 10 and a base 40. The lamp head 20 is disposed at one end of the column 10. 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 end of the column 10 through a connecting component 30. The lamp 100 may be a street lamp or floor lamp placed indoors. The light-emitting part 20a may be arranged in a strip shape. Each light-emitting part 20a may be connected and fixed to the adjacent light-emitting part 20a through a corresponding connecting structure. The first surface 21a of each light-emitting part 20a may be arranged downwards, and the second surface 21b of each light-emitting part 20a may be arranged upwards. When the included angle between adjacent light-emitting parts 20a is an obtuse angle, the cross-section of the lamp head 20 is generally bowl-shaped. When the first surface 21a is located outside the bowl-shaped structure and the second surface 21b is located inside the bowl-shaped structure, with the first surface 21a of the light-emitting part 20a configured as the light-emitting surface 20b, the multiple light-emitting parts 20a, when emitting light through their respective first surfaces 21a, can form a downward-diffuse illumination range, thus expanding the illumination coverage of the lamp head 20 when it is illuminating downwards. When both the first surface 21a and the second surface 21b are configured as light-emitting surfaces 20b, not only can the downward illumination coverage of the lamp head 20 be increased through the multiple first surfaces 21a, but the upward illumination coverage of the lamp head 20 can also be further increased through the second surface 21b, allowing the lamp head 20 to illuminate in two opposite directions.

[0026] Alternatively, the first surface 21a of each light-emitting part 20a can face to the left, and the second surface 21b of each light-emitting part 20a can face to the right. When both the first surface 21a and the second surface 21b are configured as light-emitting surfaces 20b, the lamp head 20 can emit light to both the left and the right simultaneously. When adjacent light-emitting parts 20a are arranged at an obtuse angle, the illumination coverage on at least one side can be improved. When both the first surface 21a and the second surface 21b of each light-emitting part 20a are configured as light-emitting surfaces 20b, each light-emitting part 20a can emit light in two different directions by setting two sets of lamp panels 222 arranged opposite each other.

[0027] Alternatively, the first surface 21a of a portion of the multiple light-emitting parts 20a can be configured as a light-emitting surface 20b, and the second surface 21b of a portion of the reflective parts of the multiple light-emitting parts 20a can be configured as a light-emitting surface 20b, so that the lamp head 20 can face two opposite directions to achieve staggered light emission modes and realize different light emission coverage methods.

[0028] It is understandable that when the first surface 21a is located outside the bowl of the bowl-shaped structure and the second surface 21b is located inside the bowl of the bowl-shaped structure, both the first surface 21a and the second surface 21b are configured as light-emitting surfaces 20b. The lamp head 20 can form diffuse light emission through multiple first surfaces 21a and converged light emission through multiple second surfaces 21b. In order to avoid the diffuse light emission between each light-emitting part 20a being too dispersed, resulting in poor uniformity of illumination after increasing the illumination coverage, and the converged light emission between each light-emitting part 20a being too concentrated, resulting in a small illumination coverage, the adjacent light-emitting parts 20a can be set to have a large angle. The angle between adjacent light-emitting parts 20a can be set between 160 degrees and 165 degrees. For example, the angle between adjacent light-emitting parts 20a can be set to 160 degrees, 161 degrees, 162 degrees, 163 degrees, 164 degrees, and 165 degrees.

[0029] The technical solution of this utility model involves setting a lamp 100 including a column 10 and a lamp head 20 disposed at one end of the column 10. The lamp head 20 includes 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, and adjacent light-emitting parts 20a are arranged at an obtuse angle. At least one of the first surface 21a and the second surface 21b of each light-emitting part 20a can be configured as a light-emitting surface 20b. When either the first surface 21a or the second surface 21b is configured as a light-emitting surface 20b, the plurality of light-emitting parts 20a can form a diffused illumination coverage in the same direction. The cover allows the luminaire 100 to cover a larger illumination range when illuminating in the same direction, or to form a clustered illumination coverage in the same direction. When the lamp head 20 illuminates in the same direction, it can improve the illumination brightness through multiple sets of focused illumination. When the first surface 21a and the second surface 21b of each light-emitting part 20a are both configured as light-emitting surfaces 20b, it can illuminate in two different directions at the same time. This allows the luminaire 100 to illuminate in two different directions simultaneously, and at least one direction can achieve a wider illumination coverage range. As a result, the luminaire 100 can have a larger illumination coverage range to meet the indoor comfort lighting needs.

[0030] 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.

[0031] The second surface 21b of the first light-emitting part 21 is connected to the crossbar 31 via the second sub-connecting assembly 33. This allows the lamp head 20 to be connected to the column 10 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 set 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 20 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 includes two third light-emitting parts 20a, which are respectively connected to the side of the two second light-emitting parts 22 away from the first light-emitting part 21.

[0032] 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.

[0033] like Figure 3 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.

[0034] Each light-emitting part 20a may include a lamp housing 201. The metal plate 221 and lamp plate 222 of the second light-emitting part 22 are disposed within the corresponding lamp housing 201. The first surface 21a and the second surface 21b may be two surfaces of the lamp housing 201 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] like Figure 3 As shown, at least one of the lamp panels 222 includes a first lamp panel 222a and a second lamp panel 222b. The first lamp panel 222a is attached to at least a portion of the metal plate 221 facing the first surface 21a, and the second lamp panel 222b is attached to at least a portion of the metal plate 221 facing the second surface 21b.

[0041] Understandably, since the two surfaces of the metal plate 221 have a larger area than its periphery, when the lamp plate 222 includes a first lamp plate 222a and a second lamp plate 222b, which are respectively attached to at least a portion of the two sides of the metal plate 221, the contact area between the first lamp plate 222a and the second lamp plate 222b is large. The heat generated by the operation of the first lamp plate 222a and the second lamp plate 222b can be quickly absorbed by the metal plate 221, providing heat dissipation for both lamp plates 222a and 222b. Additionally, a portion of the metal plate 221 can protrude beyond the lamp housing 201 of the second light-emitting part 22, exposing the metal plate 221 to the outdoor environment. This helps the metal plate 221 dissipate heat and ensures effective heat dissipation for the lamp plate 222.

[0042] like Figure 3 As shown, in one embodiment, the metal plate 221 includes a body portion 2211 and side portions 2212 disposed on both sides of the body portion 2211. The first lamp plate 222a is attached to the two side portions 2212, and the second lamp plate 222b is attached to the body portion 2211. The body portion 2211 is provided with a plurality of spaced ribs 22111 on the side opposite to the second lamp plate 222b.

[0043] It is understandable that when the body portion 2211 of the metal plate 221 has multiple spaced-apart ribs 22111, the ribs 22111 can act as reinforcing ribs to improve the overall structural strength of the metal plate 221. While the metal plate 221 has a heat dissipation function, it can also provide sufficient support strength for the first lamp plate 222a and the second lamp plate 222b.

[0044] When the main body 2211 has multiple raised ribs 22111 on the side opposite to the second lamp plate 222b, to prevent the first lamp plate 222a from having a small contact area with the metal plate 221, resulting in poor heat dissipation of the first lamp plate 222a, side portions 2212 can be provided on both sides of the main body 2211. This allows the first lamp plate 222a to contact the side portions 2212, thereby increasing the contact area between the first lamp plate 222a and the metal plate 221 and ensuring the heat dissipation effect of the first lamp plate 222a. In addition, the first lamp plate 222a can not only contact the side portions 2212, but also the surface of the raised ribs 22111, further increasing the contact area between the first lamp plate 222a and the metal plate 221, thus ensuring the heat dissipation effect of the metal plate 221 on the first lamp plate 222a.

[0045] like Figure 1 , Figure 2 As shown, in one embodiment, the lamp 100 further includes a column 10 and a connecting component 30, the connecting component 30 connecting the column 10 and the second surface 21b of the first light-emitting part 21.

[0046] Understandably, when mounting the lamp head 20 onto the column 10 to give the lamp fixture 100 a complete street lamp or floor lamp structure, the lamp head 20 can be mounted on the column 10 by connecting the connecting assembly 30 to the second surface 21b of the first light-emitting part 21. This avoids the situation where the light emitted by the lamp head 20 is blocked by the connecting assembly 30 when it is connected to the light-emitting part 20a (the second surface 21b of the second light-emitting part 22).

[0047] The connecting component 30 may include a first sub-connecting component 32, a crossbar 31, and a second sub-connecting component 33. One end of the crossbar 31 is rotatably connected to the lamp head 20 via the second sub-connecting component 33. The lamp head 20 can rotate relative to the crossbar 31 around a second axis. The other end of the crossbar 31 is rotatably connected to the column 10 via the first sub-connecting component 32. The crossbar 31 can rotate relative to the column 10 around a first axis. The first axis extends along a first direction, and the second axis extends along a second direction.

[0048] The first direction can be left-right, and the second direction can be perpendicular to the first direction. The lamp head 20 is oscillating relative to the column 10 around a first axis via the first sub-connecting assembly 32. The lamp head 20 can also oscillate around a horizontal axis extending left-right, and can oscillate between multiple angles (up, down, forward, and backward), allowing the lamp fixture 100 to have multiple illumination angles. When the lamp head 20 is oscillating relative to the crossbar 31 around a second axis via the second sub-connecting assembly 33, the light-emitting surface 20bb of the lamp fixture 100 can rotate within the same plane. When the lamp head 20 illuminates in the same direction, different parts of the lamp head 20 can rotate to different positions, illuminating different positions in the same direction. Combined with the multiple light-emitting parts 20a of the lamp head 20, this allows the lamp fixture 100 to have a larger illumination coverage area.

[0049] like Figure 2 As shown, the lamp head 20 also includes an auxiliary light-emitting part 23, which is disposed on at least one of the light-emitting parts 20a, or the auxiliary light-emitting part 23 is disposed between two adjacent light-emitting parts 20a.

[0050] When the auxiliary light-emitting part 23 is disposed within at least one of the light-emitting parts 20a, the auxiliary light-emitting part 23 is disposed within the lamp housing 201 of the light-emitting part 20a, or the auxiliary light-emitting part 23 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 is understood that natural sunlight contains not only visible light but also a suitable amount of near-infrared light, and 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.

[0051] like Figure 2 As shown, in one embodiment, the auxiliary light-emitting part 23 is disposed between two adjacent light-emitting parts 20a, and the auxiliary light-emitting part 23 is used to emit auxiliary light toward the side away from the second surface 21b.

[0052] It is understandable that when the auxiliary light-emitting part 23 is disposed between the two light-emitting parts 20a, it can help dissipate heat from the auxiliary light-emitting part 23 compared to disposing the auxiliary light-emitting part 23 inside the lamp housing 201 of the light-emitting part 20a. Furthermore, when the auxiliary light-emitting part 23 is disposed inside the second light-emitting part 22, since the second light-emitting part 22 itself has multiple lamp panels 222, a large amount of heat will accumulate inside the second light-emitting part 22, which is not conducive to the operation of the second light-emitting part 22.

[0053] When the auxiliary light-emitting part 23 is placed between two light-emitting parts 20a, the auxiliary light-emitting part 23 can emit scattered infrared light and supplement the infrared light of the two adjacent light-emitting parts 20a at the same time. While achieving eye protection, the number of auxiliary light-emitting parts 23 can be reduced, thereby reducing costs.

[0054] In addition, when the auxiliary light-emitting part 23 emits light in the direction away from the second surface 21b, the infrared light emitted by the auxiliary light-emitting part 23 can mix with the light emitted by the lamp head 20 facing downwards, which helps to illuminate the human body with eye-protecting light.

[0055] like Figure 3 , Figure 4 , Figure 5 As shown, in one embodiment, each light-emitting part 20a includes a lamp housing 201 and a lamp plate 222 disposed within the lamp housing 201. The lamp housing 201 has a first panel 2011 and a second panel 2012 disposed opposite to each other. The side of the first panel 2011 facing away from the second panel 2012 forms the first surface 21a, and the side of the second panel 2012 facing away from the first panel 2011 forms the second surface 21b. The first panel 2011 and / or the second panel 2012 are configured as light-transmitting plates.

[0056] It is understandable that when the auxiliary light-emitting part 23 is positioned between two adjacent light-emitting parts 20a, the lamp housings 201 of the two light-emitting parts 20a located on both sides of the auxiliary light-emitting part 23 can be connected and fixed to the outer shell of the auxiliary light-emitting part 23. When the lamp panel 222 inside the lamp housing 201 emits light towards the first surface 21a, the first panel 2011 can be configured as a light-transmitting panel, and the side of the first panel 2011 facing away from the second panel 2012 can form the first surface 21a, so that the light emitted by the lamp panel 222 towards the first panel 2011 can pass through. When the lamp panel 222 inside the lamp housing 201 emits light towards the second surface 21b, the second panel 2012 can be configured as a light-transmitting panel, and the side of the second panel 2012 facing away from the first panel 2011 can be configured as the second surface 21b, so that the light emitted by the lamp panel 222 towards the second panel 2012 can pass through.

[0057] like Figure 3 , Figure 4 , Figure 5 As shown, in one embodiment, the lamp panel 222 includes a lamp panel body 2221 and a plurality of lamp beads 2222 disposed on one side of the lamp panel body 2221. The plurality of lamp beads 2222 are spaced apart and are located on the side of the lamp panel body 2221 facing the first surface 21a or facing the second surface 21b. At least some of the lamp beads 2222 are covered with lamp covers 2223 on their outer surfaces.

[0058] The multiple LED beads 2222 can be distributed on the side of the lamp panel body 2221 facing the first surface 21a, so that the lamp panel 222 emits light towards the first surface 21a. Alternatively, the multiple LED beads 2222 can be distributed on the side of the lamp panel body 2221 facing the second surface 21b, so that the lamp panel 222 emits light towards the second surface 21b. It can be understood that when the first surface 21a is facing upwards and the second surface 21b is facing upwards, when the lamp panel 222 emits light towards the first surface 21a, the lamp head 20 emits light downwards to provide illumination; when the lamp panel 222 emits light towards the second surface 21b, the lamp head 20 emits light downwards to provide illumination. Here, a lampshade 2223 can be placed on the outer surface of the LED beads 2222 of the downward-emitting light panel 222 to scatter and mix the light emitted by the LED beads 2222, preventing the downward-emitting light from shining directly into the eyes and causing discomfort. Since the upward-emitting light panel 222 does not shine directly towards the human body, it is not necessary to place a lampshade 2223 on the outer surface of the LED beads 2222 of the upward-emitting light panel 222, thereby reducing the cost of the lamp head 20.

[0059] Alternatively, in other embodiments, a lampshade 2223 may be provided on the outer surface of each lamp bead 2222 of the lamp board 222, without any specific limitation.

[0060] 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.
