[0005] In one embodiment, the surface of the light-emitting element that faces away from the reflective surface is the light-emitting surface. In the first state, along the direction from the first end to the second end, the surface of the light-emitting element near the reflective surface is inclined upward.

[0006] In one embodiment, in the first state, the upward tilt angle of the surface of the light-emitting element near the reflective surface is the same as or different from the upward tilt angle of the light-emitting surface.

[0007] In one embodiment, in the first state, the angle between the light-emitting surface and the first direction is α, where 5°≤α≤30°; And / or, the width of the light outlet along the first direction is W, 10mm≤W≤50mm.

[0008] In one embodiment, the lamp head includes a lampshade and a fixing member. The lampshade has an opening on one side. The reflector, light-emitting element, and light-emitting element are disposed inside the lampshade. The fixing member is disposed at the opening and connected to the lampshade, and the fixing member defines the light-emitting port. The light-emitting element is supported on the fixing member and covers the light-emitting port, or the light-emitting element is disposed inside the light-emitting port and connected to the fixing member. And / or, the fastener is arranged in a ring shape.

[0009] In one embodiment, the bottom of the lamp head is provided with a light-blocking part, which is located at the first end and outside the light outlet.

[0010] In one embodiment, the height of the light-blocking part is H1, where 1mm ≤ H1 ≤ 10mm.

[0011] In one embodiment, the lamp further includes a lamp post, which is connected to the second end of the lamp head. The light-emitting element is disposed on the side of the reflector near the lamp post. The light-emitting element is connected to the reflector and / or the lamp head, and the light-emitting element and / or the reflector is supported on the light-emitting element.

[0012] In one embodiment, along the second direction, the height between the bottom of the lamp post and the bottom of the lamp head is H2, where 400mm ≤ H2 ≤ 600mm.

[0013] In one embodiment, the light-emitting element is disposed on the side of the reflector near the second end; the light-emitting element includes a lamp board and lamp beads, the lamp board has a mounting surface for mounting the lamp beads, and in the first state, the mounting surface is inclined relative to the second direction.

[0014] In one embodiment, along the direction from the second end to the first end, the bottom of the mounting surface is located on the side of the top of the mounting surface near the second end; And / or, the angle between the mounting surface and the second direction is β, where 5°≤β≤30°.

[0015] In the technical solution of this application, the lamp includes a lamp head, a reflector, a light-emitting element, and a light-emitting element. The reflector has a reflective surface on the side near the light-emitting port. The light-emitting direction of the light-emitting element is towards the reflective surface. The reflective surface is used to reflect at least part of the light emitted by the light-emitting element toward the light-emitting port. The light-emitting element is disposed inside the light-emitting port, or the light-emitting element is disposed inside the lamp head and covers the light-emitting port. The light-emitting element has a light-emitting surface. The lamp has a first state. In the first state, the light-emitting surface is inclined upward along the direction from the first end to the second end. This design allows the reflective surface to guide the light scattered by the light-emitting element to the light-emitting element inside the light outlet through reflection. The reflected light is then emitted outward through the light-emitting surface of the light-emitting element. The reflective surface improves the utilization rate of light, constrains the diffusion range of light, and disperses the concentration point of light, preventing light from shining directly into the eyes. This prevents users from looking directly at the light emitted by the light-emitting element, thereby improving the softness and visibility of the light to a certain extent and avoiding glare. Furthermore, when the light outlet is set directly downward, the light-emitting surface is tilted upward from the first end to the second end. When the user observes from one side of the first end of the lamp head, and both the user's line of sight and the light-emitting surface are tilted upward in the same direction, the user's line of sight will not see the light-emitting element inside the lamp head, thus preventing the light from shining directly into the user's eyes. This further improves the anti-glare effect, and the light-emitting element makes the projected light more uniform and softer.

[0016] For example, consider a lamp installed on a table, used by a user in front of the table. The lamp head has a first end and a second end opposite each other along a first direction. In a first state, the light-emitting surface is tilted upwards along the direction from the first end to the second end. The user observes the lamp from one side of the first end of the lamp head. Figure 2 As shown, the user's eye observes from observation point A. At this time, the line of sight of the human eye is tilted upward, and the light-emitting surface in this application is also tilted upward. Since the user is at a certain distance from the lamp head when using the lamp, when observation point A is at a preset distance and preset height from the lamp head, the line of sight of the human eye will not directly observe the reflector and light-emitting component inside the lamp head, thus improving the anti-glare effect of the lamp.

[0024] In related technologies, lighting fixtures generally refer to devices with lighting functions. Lighting fixtures can illuminate the space in which they are installed; for example, lighting fixtures can be installed on a table so that users can work, study, etc. However, existing lighting fixtures are prone to producing glare, which affects the user experience.

[0025] Based on the above considerations, in order to solve the problem of glare easily generated by existing lamps, this application proposes a new lamp. This lamp uses a reflective surface to reflect at least a portion of the light emitted by the light-emitting element towards the light-emitting element at the light-emitting port, so that the light is emitted outward through the light-emitting surface of the light-emitting element. The reflective surface improves the utilization rate of the light, restricts the diffusion range of the light, disperses the concentration point of the light, and prevents the light from shining directly into the eyes. This prevents the user from looking directly at the light emitted directly by the light-emitting element, thereby improving the softness and visibility of the light to a certain extent and avoiding glare. Furthermore, the light-emitting surface of the light-emitting element is inclined upward along the width direction of the lamp head. When the user observes from one side of the lamp head along the width direction, and the line of sight of the user's eyes and the light-emitting surface are both inclined upward in the same direction, the line of sight of the user's eyes will not see the light-emitting element and the light-emitting element inside the lamp head, thus preventing the light from shining directly into the user's eyes. This further improves the anti-glare effect, and the light-emitting element makes the projected light more uniform and softer.

[0026] The structures in the embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0027] Please see Figures 1 to 7In one embodiment of this application, the lamp 10 includes a lamp head 100, a reflector 200, a light-emitting element 300, and a light-exiting element 400. The lamp head 100 has a light-exiting opening 101. The width direction of the lamp head 100 is a first direction, and the height direction of the lamp head 100 is a second direction. The lamp head 100 has a first end 100a and a second end 100b arranged opposite to each other along the first direction. The reflector 200 is disposed inside the lamp head 100, and the side of the reflector 200 near the light-exiting opening 101 has a reflective surface 201. The light-emitting element 300... The light-emitting element 300 is disposed inside the lamp head 100, and its light emission direction is towards the reflective surface 201. The reflective surface 201 is used to reflect at least part of the light emitted by the light-emitting element 300 toward the light outlet 101. The light-emitting element 400 is disposed inside the light outlet 101, or the light-emitting element 400 is disposed inside the lamp head 100 and covers the light outlet 101. The light-emitting element 400 has a light-emitting surface 401. The lamp 10 has a first state. In the first state, the light-emitting surface 401 is inclined upward along the direction from the first end 100a to the second end 100b.

[0028] It is understood that the lamp 10 can be installed on a table, which may include table corners and a tabletop located on the table corners, with the lamp 10 installed on the tabletop. Of course, in other embodiments, the lamp 10 can also be fixed to a wall or other location, and the installation can be carried out as needed.

[0029] For example, the lamp 10 also includes a lamp post 600, and a lamp head 100 is disposed on the lamp post 600. The lamp head 100 may be fixed to the lamp post 600, or the lamp head 100 may be movably disposed on the lamp post 600. The movability may be in the form of rotation, sliding, etc., that is, the lamp head 100 may be rotatably disposed on the lamp post 600, or the lamp head 100 may be slidably disposed on the lamp post 600. The specific details are not limited here.

[0030] like Figures 1 to 7 As shown, the width direction of the lamp head 100 is the first direction X, and the height direction of the lamp head 100 is the second direction Y. The first direction X and the second direction Y are set perpendicularly.

[0031] The reflective surface 201 is used to reflect light. For example, the reflective surface 201 is an arc-shaped surface that is recessed in the direction away from the light-emitting element 300 and / or the light-emitting element 400. This configuration ensures that the reflective surface 201 reflects as much light as possible from the light-emitting element 300, and also improves the uniformity of the light reflected by the reflective surface 201 to a certain extent, thereby improving the light emission effect.

[0032] For example, the reflector 200 is a component made of reflective material, or the reflector 200 can be reflective paper, reflective film, reflective coating, etc., which are not specifically limited here.

[0033] For example, the light-emitting element 300 includes a lamp board 310 and lamp beads 320. The lamp beads 320 are disposed on the lamp board 310, and the number of lamp beads 320 can be one, two, or more, and the specific number is not limited. In this embodiment, the lamp board 310 is provided with a plurality of lamp beads 320, and the plurality of lamp beads 320 are arranged sequentially at intervals along the length direction of the lamp board 310, which is beneficial to improving the brightness and illumination range of the light.

[0034] For example, the light-emitting element 400 is disposed within the light-emitting port 101, or the light-emitting element 400 is disposed within the lamp head 100 and covers the light-emitting port 101, that is, the light-emitting element 400 is disposed on the light-emitting side of the reflective surface 201 to prevent glare from at least a portion of the light reflected by the reflective surface 201. Specifically, the light emitted outward from the light-emitting surface 401 of the light-emitting element 400 can be projected downwards, including light projected directly downwards and light projected obliquely downwards. In other words, at least a portion of the light emitted by the light-emitting element 300 is projected onto the reflective surface 201 of the reflective element 200. The reflective surface 201 can reflect at least a portion of the light projected onto it, and since the light-emitting element 400 is disposed on the light-emitting side of the reflective surface 201, the light emitted by the light-emitting element 300 can be processed by the light-emitting element 400 when projected onto the reflective surface 201, and the processed light can be used by the user.

[0035] The shape of the light-emitting element 400 is not limited, and may be, for example but not limited to, plate-shaped or block-shaped. The light-emitting element 400 has a light-emitting surface 401, which is the surface of the light-emitting element 400 that faces away from the reflective surface 201. Light rays are emitted outward through the light-emitting surface 401. The light-emitting surface 401 may be planar; or, the light-emitting surface 401 may be arc-shaped; or, part of the light-emitting surface 401 may be planar and the other part may be arc-shaped. The specific shape is not limited here.

[0036] For example, the light-emitting element 400 can be a prism plate, a composite brightness enhancement film, or a light-transmitting element such as glass.

[0037] The luminaire 10 has a first state, exemplarily, such as Figure 5 As shown, in the first state, the center line of the light-emitting port 101 is along the second direction Y and the light-emitting port 101 is set downwards, that is, the light-emitting port 101 is set directly downwards. The lamp 10 may only have the first state, that is, the orientation of the light-emitting port 101 is not adjustable; of course, the lamp 10 may also have other states, for example, the lamp 10 may have a second state, in which the center line of the light-emitting port 101 is inclined relative to the height of the lamp head 100. For example, the lamp 10 includes a lamp post 600, and the lamp head 100 is rotatably mounted on the lamp post 600 so that the lamp 10 has the aforementioned first state and second state.

[0038] In the first state, the light-emitting surface 401 is tilted upward along the first direction X. The specific tilt angle of the light-emitting surface 401 is not limited here. For example, but not limited to: 5°, 8°, 10°, 12°, 15°, 18°, 20°, 22°, 25°, 28° or 30°, or any value within the above range.

[0039] In the technical solution of this application, the lamp 10 includes a lamp head 100, a reflector 200, a light-emitting element 300, and a light-emitting element 400. The reflector 200 has a reflective surface 201 on the side near the light outlet 101. The light-emitting direction of the light-emitting element 300 is towards the reflective surface 201. The reflective surface 201 is used to reflect at least part of the light emitted by the light-emitting element 300 toward the light outlet 101. The light-emitting element 400 is disposed in the light outlet 101 and has a light-emitting surface 401. The lamp 10 has a first state. In the first state, the center line of the light outlet 101 is along the second direction Y and the light outlet 101 is set downward. Along the direction from the first end 100a to the second end 100b, the light-emitting surface 401 is set upward at an angle. This configuration allows the reflective surface 201 to guide the light scattered in all directions by the light-emitting element 300 to the light-emitting element 400 inside the light-emitting port 101 via reflection. The reflected light is then emitted outward through the light-emitting surface 401 of the light-emitting element 400. The reflective surface 201 improves the utilization rate of light, restricts the diffusion range of light, disperses the concentration point of light, and prevents light from directly hitting the eyes. This prevents users from looking directly at the light emitted directly from the light-emitting element 300, thereby improving the softness and visibility of the light to a certain extent and avoiding glare. Furthermore, when the light outlet 101 is set directly downwards, the light-emitting surface 401 is tilted upwards along the direction from the first end 100a to the second end 100b. When the user observes from one side of the first end 100a of the lamp head 100, and the line of sight of the human eye and the light-emitting surface 401 are both tilted upwards in the same direction, the line of sight of the human eye will not see the light-emitting element 300 inside the lamp head 100, so as to avoid the light directly looking into the user's eyes. This further improves the anti-glare effect, and the light-emitting element 400 makes the projected light more uniform and softer.

[0040] For example, taking a lamp 10 mounted on a table and used by a user in front of the table, the lamp head 100 has a first end 100a and a second end 100b opposite each other along a first direction X. In a first state, the light-emitting surface 401 is tilted upward along the direction from the first end 100a to the second end 100b. The user observes the lamp from one side of the first end 100a of the lamp head 100. Figure 2As shown, the user's eye observes from observation point A. At this time, the line of sight of the human eye is tilted upward, and the light-emitting surface 401 in this application is also tilted upward. Since the user has a certain distance from the lamp head 100 when using the lamp 10, when the observation point A has a preset distance and preset height from the lamp head 100, the line of sight of the human eye will not directly observe the reflector 200 and the light-emitting element 300 inside the lamp head 100, thus improving the anti-glare effect of the lamp 10.

[0041] For example, in Figure 2 In the diagram, observation point A is the test point. The distance L1 between test point A and the center line of the light outlet 101 is 600mm, and the height H3 between test point A and the bottom of the lamp 10 is 400mm. Of course, in other embodiments, test point A can also be located at other positions, that is, the specific values ​​of the distances L1 and H3 between test point A and the lamp 10 are not limited.

[0042] Please see Figures 3 to 7 According to some embodiments of this application, optionally, the surface of the light-emitting element 400 that is away from the reflective surface 201 is the light-emitting surface 401. In the first state, along the direction from the first end 100a to the second end 100b, the surface of the light-emitting element 400 near the reflective surface 201 is inclined upward.

[0043] The light-emitting element 400 is disposed below the reflective surface 201, that is, on the light-emitting side of the reflective surface 201, to prevent glare from at least a portion of the light reflected by the reflective surface 201. In this embodiment, the light-emitting element 400 has a surface close to the reflective surface 201 and a surface away from the reflective surface 201. The surface of the light-emitting element 400 away from the reflective surface 201 is the light-emitting surface 401. In the first state, the reflective element 200 reflects light towards the light-emitting element 400. The light enters the light-emitting element 400 from the surface close to the reflective surface 201 and exits outward through the light-emitting surface 401. The surface of the light-emitting element 400 close to the reflective surface 201 can be planar; or curved; or partly planar and partly curved, and the specific details are not limited here.

[0044] In the first state, along the direction from the first end 100a to the second end 100b, the surface of the light-emitting element 400 near the reflective surface 201 is inclined upward. The upward inclination angle of the surface of the light-emitting element 400 near the reflective surface 201 can be the same as or different from the upward inclination angle of the light-emitting surface 401. For example, the upward inclination angle of the surface of the light-emitting element 400 near the reflective surface 201 can be 5°, 8°, 10°, 12°, 15°, 18°, 20°, 22°, 25°, 28° or 30°, or any value within the above range.

[0045] In this embodiment, in the first state, along the direction from the first end 100a to the second end 100b, the surface of the light-emitting element 400 near the reflective surface 201 is inclined upwards, and the light-emitting surface 401 is also inclined upwards, so that the inclined direction of the surface of the light-emitting element 400 near the reflective surface 201 and the light-emitting surface 401 is the same. The light-emitting element 400 has a structure that is inclined in the same direction, which is beneficial to the folding of the light path, reduces the secondary reflection loss of light in the light-emitting element 400, and improves the light efficiency utilization rate; in addition, it also improves the consistency of the light-emitting element 400, so as to facilitate the processing of the light-emitting element 400.

[0046] According to some embodiments of this application, optionally, in a first state, the upward tilt angle of the surface of the light-emitting element 400 near the reflective surface 201 is the same as or different from the upward tilt angle of the light-emitting surface 401. Specifically, in this embodiment, the upward tilt angle of the surface of the light-emitting element 400 near the reflective surface 201 is the same as the upward tilt angle of the light-emitting surface 401, making the light-emitting element 400 a structure tilted in the same direction. This is beneficial for the folding of the light path, reducing secondary reflection loss of light within the light-emitting element 400, and improving light efficiency. Of course, in other embodiments, the upward tilt angle of the surface of the light-emitting element 400 near the reflective surface 201 can also be different from the upward tilt angle of the light-emitting surface 401. In this case, an adaptive adjustment can be made according to the internal structure and light emission angle of the lamp head 100.

[0047] According to some embodiments of this application, optionally, in the first state, the angle between the light-emitting surface 401 and the first direction X is α, 5°≤α≤30°; and / or, the width of the light-emitting port 101 along the first direction X is W, 10mm≤W≤50mm.

[0048] It is understandable that, such as Figure 6 and Figure 7 As shown, the included angle α can be 5°, 8°, 10°, 12°, 15°, 18°, 20°, 22°, 25°, 28°, or 30°, or any value within the above range. In the first state, by limiting the upward tilt angle of the light-emitting surface 401 to α, when the user observes from one side of the lamp head 100 along the width direction, and both the user's line of sight and the light-emitting surface 401 are tilted upward in the same direction, the user's line of sight will not observe the light-emitting element 300 inside the lamp head 100, thus avoiding direct light into the user's eyes. This improves the anti-glare effect, and the light-emitting element 400 makes the projected light more uniform and softer. For example, in the first state, the included angle between the light-emitting surface 401 and the first direction X is α, where 10°≤α≤20°.

[0049] like Figure 6 and Figure 7As shown, the width W can be 10mm, 12mm, 15mm, 18mm, 20mm, 22mm, 25mm, 28mm, 30mm, 32mm, 35mm, 38mm, 40mm, 42mm, 45mm, 48mm, or 50mm, or any value within the above range. By limiting the width of the light outlet 101, large-angle diffused light can be blocked. Combined with the upward tilt of the light-emitting surface 401, this improves light utilization and anti-glare effect. For example, the width of the light outlet 101 along the first direction X is W, where 20mm ≤ W ≤ 40mm.

[0050] Please see Figures 3 to 7 According to some embodiments of this application, optionally, the bottom of the lamp head 100 is provided with a light blocking part 500, which is located at the first end 100a and outside the light outlet 101.

[0051] It is understood that the light-blocking part 500 can be a light-blocking flange or a light-blocking strip, etc. The light-blocking part 500 can be provided at the bottom of the lamp head 100 along the length direction of the lamp head 100. For example, the light-blocking part 500 is provided on the side of the lamp head 100 closer to the user. For example, when the lamp 10 is installed on a table, the light-blocking part 500 is positioned opposite to the user, and the light-blocking part 500 blocks the light-emitting element 400, thereby preventing the light emitted from the light-emitting surface 401 from directly shining into the user's eyes, thus improving the anti-glare effect of the lamp 10.

[0052] For example, the light-blocking part 500 and the lamp holder 100 are integrally formed. This configuration improves the overall structural strength of the light-blocking part 500 and the lamp holder 100, and also facilitates the assembly of the lamp 10. In this embodiment, by providing a light-blocking part 500 at the bottom of the lamp head 100, the light emitted from the light-emitting surface 401 can be guided and blocked to avoid the user looking directly at the light-emitting surface 401 of the light-emitting element 400 and causing glare. It also helps to improve the uniformity of light emitted by the lamp 10.

[0053] According to some embodiments of this application, optionally, the height of the light-blocking part 500 is H1, where 1mm≤H1≤10mm.

[0054] It is understandable that, such as Figure 6 and Figure 7As shown, the height H1 can be 1mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, 4.0mm, 4.5mm, 5.0mm, 5.5mm, 6.0mm, 6.5mm, 7.0mm, 7.5mm, 8.0mm, 8.5mm, 9.0mm, 9.5mm, or 10.0mm, or any value within the above range. By limiting the height of the light-blocking part 500 to the above range, the light-blocking part 500 can achieve the functions of blocking light and preventing glare, and also makes the lamp 10 aesthetically pleasing. For example, 3.3mm ≤ H1 ≤ 8.7mm.

[0055] According to some embodiments of this application, optionally, the lamp 10 further includes a lamp post 600, which is connected to the second end 100b of the lamp head 100. The light-emitting element 300 is disposed on the side of the reflector 200 near the lamp post 600. The light-emitting element 300 is connected to the reflector 200 and / or the lamp head 100. The light-emitting element 300 and / or the reflector 200 are supported on the light-emitting element 400.

[0056] For example, the light-emitting element 300 is connected and fixed to the reflector 200 by a connector, which can be a screw or the like. The reflector 200 is snapped and fixed to the lamp holder 100. Both the light-emitting element 300 and the reflector 200 are supported on the light-emitting element 400, which helps to improve the stability of the internal structure of the lamp holder 100 during installation.

[0057] In this embodiment, the light-emitting element 300 is disposed on the side of the reflector 200 near the lamp post 600, thus achieving the side-emitting effect of the lamp 10. The light-emitting element 300 and / or the reflector 200 are supported on the light-emitting element 400, which improves the utilization rate of the light-emitting element 400 and helps to improve the internal structural compactness of the lamp head 100. Furthermore, the light emitted from the side by the light-emitting element 300 is reflected by the reflector 201 and then emitted outward from the light-emitting surface 401. The reflector 201 improves the utilization rate of the light, constrains the diffusion range of the light, disperses the concentration point of the light, and prevents the light from shining directly into the eyes, so that the user will not look directly at the light emitted directly by the light-emitting element 300, thereby improving the softness and visibility of the light to a certain extent and avoiding the occurrence of glare.

[0058] According to some embodiments of this application, optionally, along the second direction Y, the height between the bottom of the lamp post 600 and the bottom of the lamp head 100 is H2, where 400mm≤H2≤600mm.

[0059] like Figure 6 and Figure 7As shown, the height H2 can be 400mm, 420mm, 450mm, 480mm, 500mm, 520mm, 550mm, 580mm, or 600mm, or any value within the above range. By limiting the height between the bottom of the lamp post 600 and the bottom of the lamp head 100 to within the above range, the installation height of the lamp head 100 is effectively limited. Combined with the height of the light-blocking part 500, this helps to improve the anti-glare effect. For example, 495mm ≤ H2 ≤ 550mm.

[0060] Please see Figures 4 to 7 According to some embodiments of this application, optionally, the lamp head 100 includes a lampshade 110 and a fixing member 120. The lampshade 110 has an opening on one side. The reflector 200, the light-emitting element 300, and the light-emitting element 400 are disposed inside the lampshade 110. The fixing member 120 is disposed at the opening and connected to the lampshade 110. The fixing member 120 and the lampshade 110 define a light-emitting port 101. The light-emitting element 400 is supported on the fixing member 120 and covers the light-emitting port 101. Alternatively, the light-emitting element 400 is disposed inside the light-emitting port 101 and connected to the fixing member 120. And / or, the fixing member 120 is arranged in a ring shape.

[0061] It is understood that the connection method between the fastener 120 and the lampshade 110 is not limited, for example but not limited to: connection and fixation by a connector; or connection and fixation by a snap-fit ​​structure; or fixation by ultrasonic welding. In this embodiment, the fastener 120 and the lampshade 110 are fixed by ultrasonic welding, which improves the connection stability.

[0062] The fixing member 120 has a bearing surface, and the light-emitting member 400 is supported on the bearing surface and covers the light-emitting port 101. Alternatively, the light-emitting member 400 is disposed in the light-emitting port 101 and connected to the fixing member 120, so as to realize the accurate installation of the light-emitting member 400, and also improve the stability of the installation of the light-emitting member 400, thereby improving the reliability of the lamp 10.

[0063] The fastener 120 is arranged in a ring shape, which helps to improve the structural strength of the fastener 120. The fastener 120 is arranged in a ring around the opening of the lampshade 110 to support the peripheral wall of the opening of the lampshade 110. This helps to reduce the local stress on the lampshade 110 when it is subjected to external impact, thereby improving the structural strength of the lampshade 110.

[0064] Please see Figures 4 to 7 According to some embodiments of this application, optionally, the light-emitting element 300 is disposed on the side of the reflector 200 near the second end 100b; the light-emitting element 300 includes a lamp board 310 and an LED 320, the lamp board 310 has a mounting surface 301 for mounting the LED 320, and in a first state, the mounting surface 301 is inclined relative to the second direction Y.

[0065] It is understood that the LED beads 320 are disposed on the mounting surface 301 of the lamp board 310, and the number of LED beads 320 can be one, two, or more, with no specific limitation. In this embodiment, the lamp board 310 has a mounting surface 301, which is oriented from the second end 100b towards the first end 100a. Multiple LED beads 320 are disposed on the mounting surface 301, and the multiple LED beads 320 are arranged sequentially at intervals along the length direction of the lamp board 310. This helps to reduce the number of LED beads 320 used and lower manufacturing costs.

[0066] In this embodiment, the light-emitting element 300 is disposed on the side of the reflector 200 near the second end 100b, and the light-emitting surface 401 is inclined upward. The lamp bead 320 is mounted on the mounting surface 301 of the lamp board 310, with the mounting surface 301 facing the first end 100a. This allows the light-emitting element 300 to emit light from the second end 100b toward the first end 100a, thus achieving the side-emitting effect of the lamp 10. The light emitted from the side by the light-emitting element 300 is reflected by the reflector 201 and then emitted outward from the light-emitting surface 401. The reflector 201 improves the utilization rate of light, constrains the diffusion range of light, disperses the concentration point of light, and prevents light from shining directly into the eyes. In addition, in conjunction with the inclined light-emitting element 400, the user will not look directly at the light emitted directly by the light-emitting element 300, thereby improving the softness and visibility of the light to a certain extent and avoiding the occurrence of glare.

[0067] According to some embodiments of this application, optionally, along the direction from the second end 100b to the first end 100a, the bottom of the mounting surface 301 is located on the side of the top of the mounting surface 301 close to the second end 100b; and / or, the angle between the mounting surface 301 and the second direction Y is β, where 5°≤β≤30°.

[0068] It is understandable that, along the first direction X, the bottom of the mounting surface 301 is located on the side of the top of the mounting surface 301 near the second end 100b, that is, the mounting surface 301 is inclined from bottom to top towards the side near the reflector 200. The lamp plate 310 and the reflector 200 occupy less of the overall width in the width direction of the lamp head 100, which improves the structural compactness. Furthermore, the reflector 200 and the light-emitting element 300 are both supported on the light-emitting element 400. The reflector 200, the light-emitting element 300 and the light-emitting element 400 together form an acute triangle, which improves the stability of the installation and cooperation of the three.

[0069] like Figure 6 and Figure 7As shown, the value of β can be 5°, 8°, 10°, 12°, 15°, 18°, 20°, 22°, 25°, 28°, or 30°, or any value within the above range. By limiting the size of β, the reflective surface 201 can effectively reflect the light emitted by the light-emitting element 300, and it can also prevent the light emitted by the light-emitting element 300 from being directly projected outside the lamp head 100 without being reflected by the reflective surface 201, thus ensuring the side emission of the lamp 10 and further effectively preventing glare.

[0070] For example, 10°≤β≤20°, where the value of β can be 10°, 12°, 15°, 18°, or 20°, or any value within the above range.

[0071] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope 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 patent protection scope of the present utility model.
