[0045] The present invention will be further described in detail below with reference to the drawings and specific embodiments. Specific Embodiments

[0046] As Figures 1 to 7 shown in the figure, this embodiment provides an LED lamp capable of adjusting the size and direction of the light-emitting port. The LED lamp includes a housing 100 and a light-dimming board 200.

[0047] Among them, the housing 100 has a light-emitting port 110 for the light of the LED lamp to emit therefrom, and the light-emitting port 110 can also be the installation position of the LED lamp.

[0048] The number of the light-dimming boards 200 is at least two. The multiple light-dimming boards 200 are arranged staggeredly around the light-emitting port 110, so that the multiple light-dimming boards 200 respectively guide and constrain the light on different sides of the light-emitting port 110. The light-dimming board 200 extends outward relative to the light-emitting port 110, so as to guide and constrain the light emitted from the light-emitting port 110. The first end of each light-dimming board 200 is movably connected to the housing 100 independently, that is, each light-dimming board 200 is connected to the housing 100 and can move relative to the housing 100 independently without affecting each other at the connection. The movement can include moving or rotating, so that the angle between the extending direction of each light-dimming board 200 and the normal direction of the light-emitting port 110 is independently adjustable, so that the second ends of at least two light-dimming boards 200 can approach or move away from each other.

[0049] In this embodiment, the first end of the light-dimming board 200 can move independently relative to the housing 100, so that the angle between the extending direction of the light-dimming board 200 and the normal direction of the light-emitting port 110 can be adjusted independently, so as to adjust the direction of the light-emitting port. At the same time, the second end of the light-dimming board 200 constitutes a part of the light-emitting port, and the second ends of the light-dimming boards 200 can approach or move away from each other to adjust the size of the light-emitting port. The extending direction of the light-dimming board 200 refers to the direction of the board of the light-dimming board 200 itself, and the normal direction of the light-emitting port 110 refers to the vertical direction of the plane where the light-emitting port 110 is located. For example, light-dimming boards 200 are respectively arranged on both sides of a light-emitting port 110. When the light-dimming boards 200 on both sides move synchronously, the light-emitting direction of the light-emitting port can be changed; when the light-dimming boards 200 on both sides move towards each other, the light-emitting port can be made smaller; when the light-dimming boards 200 on both sides move in the opposite direction, the light-emitting port can be made larger. When adjusting the light-dimming board 200, one light-dimming board 200 can be adjusted while keeping the other light-dimming board 200 stationary, or multiple light-dimming boards 200 can be adjusted simultaneously. The adjustment of the light-dimming board 200 can be carried out manually or electrically. It can be seen that the LED lamp of this embodiment can flexibly adjust the size and direction of the light-emitting port, can enrich the light-emitting effect of the LED lamp, and improve the application flexibility of the LED lamp.

[0050] In some examples, the housing 100 and the dimming plate 200 may be made of an opaque material such as opaque plastic, so that most of the light can only be emitted from the light outlet formed by the second end of the dimming plate 200 .

[0051] In some examples, the housing 100 includes a first side plate 120 and a second side plate 130, which are arranged relative to each other in a first direction perpendicular to the normal direction of the light outlet 110 and extend outward from two opposite sides of the light outlet 110. The dimming plate 200 is sandwiched between the first side plate 120 and the second side plate 130, and the first ends of the two dimming plates 200 are arranged relative to each other in a second direction perpendicular to the normal direction of the light outlet 110, and the first direction and the second direction are perpendicular to each other. The first side plate 120, the second side plate 130 and the two dimming plates 200 together constitute a light outlet, so that the structure of the light outlet is more regular, and the adjustment of the dimming plates 200 is more convenient and easy to control.

[0052] In some examples, the first end of the dimming plate 200 is rotatably disposed between the first side plate 120 and the second side plate 130, and at least one of the first side plate 120 and the second side plate 130 can support the dimming plate 200. The dimming plate 200 is connected to the shell in a rotatable manner, and the adjustment of the dimming plate 200 is simpler and easier to control.

[0053] In some examples, one side of the dimming plate 200 is adjacent to the first side plate 120, and the other side is adjacent to the second side plate 130. Here, the one side and the other side of the dimming plate 200 refer to the two sides of the dimming plate 200 in the direction from the first end to the second end. The two sides of the dimming plate 200 are adjacent to the first side plate 120 and the second side plate 130 respectively, which can prevent light from leaking from between the dimming plate 200 and the first side plate 120, or from between the dimming plate 200 and the second side plate 130.

[0054] In some examples, the first side plate 120 is provided with a through hole 121 that penetrates the first side plate 120 along the first direction, and the first end of the dimming plate 200 is provided with a positioning hole 210 that extends along the first direction. The through hole 121 and the positioning hole 210 are aligned with each other and connected by a rotating shaft, and the first side plate 120 and the dimming plate 200 are rotatably connected by the rotating shaft. The rotating shaft and the dimming plate 200 can be transitionally matched or clearance matched, and the rotating shaft and the through hole 121 can be interference matched or fixedly connected, so that the dimming plate 200 can be rotated relative to the rotating shaft to achieve angle adjustment. It is best that the dimming plate 200 needs to rotate relative to the rotating shaft under certain force conditions, and remain stationary relative to the rotating shaft when no force is applied, so as to avoid shaking or undesirable movement of the dimming plate 200.

[0055] In some examples, a boss 122 is provided on the first side of the first side plate 120 close to the second side plate 130. The through hole 121 passes through the boss 122. The boss 122 can improve the mechanical properties of the connection and increase the connection strength. A recessed portion 220 that cooperates with the boss 122 is provided at the first end of the light dimming plate 200. The positioning hole 210 leads to the recessed portion 220. By the cooperation of the recessed portion 220 and the boss 122, not only can the accurate positioning of the light dimming plate 200 and the first side plate 120 be achieved, but also the light dimming plate 200 and the first side plate 120 can be tightly connected to avoid light leakage.

[0056] In some examples, a counterbore 123 is provided on the second side of the first side plate 120 away from the second side plate 130. The through hole 121 passes through or leads to the counterbore 123. The counterbore 123 is beneficial to the installation and positioning of the rotating shaft.

[0057] In some examples, the through hole 121 leads to the outside of the housing 100, facilitating the installation of the rotating shaft through the through hole.

[0058] In some examples, the first side plate 120 and the second side plate 130 extend along the normal direction of the light exit port 110. The first side plate 120 and the second side plate 130 are parallel to each other. The two sides of the light dimming plate 200 can be straight lines parallel to each other, making the matching structure between the light dimming plate 200 and the first side plate 120 and the second side plate 130 more regular and simple.

[0059] In some examples, the housing 100 further includes a third side plate 140 and a fourth side plate 150 provided between the first side plate 120 and the second side plate 130. The third side plate 140 and the fourth side plate 150 are oppositely arranged in the second direction and extend outward from two opposite sides of the light exit port 110. The light dimming plate 200 is located between the third side plate 140 and the fourth side plate 150. The third side plate 140 and the fourth side plate 150 can limit the moving area of the light dimming plate 200.

[0060] In some examples, the distance between the third side plate 140 and the fourth side plate 150 gradually increases in the direction away from the light exit port 110, providing a range for the movement of the light dimming plate 200. At the same time, the distance between the third side plate 140 and the fourth side plate 150 gradually decreases in the direction close to the light exit port 110, reducing the area of the light output channel and avoiding dust accumulation.

[0061] In some examples, the third side plate 140 and the fourth side plate 150 are respectively provided with recessed portions 151 near the light emission outlet 110. The first end of the light dimming plate 200 is provided with a movable connection portion bent relative to the main body of the light dimming plate 200. The positioning hole 210 can be provided in the movable connection portion. The movable connection portion at least partially extends into the recessed portion 151 and is movably connected to the housing 100, so that light does not directly leak from the gap between the third side plate 140 or the fourth side plate 150 and the first end of the light dimming plate 200, and at the same time, the light blocking of the first end of the light dimming plate 200 in the light propagation path is also reduced.

[0062] In some examples, the recessed portion 151 includes an intermediate region 152, a first relief region 153, and a second relief region 154. The intermediate region 152 can be provided corresponding to the through hole 121. The movable connection portion at least partially extends into the intermediate region 152, so that the positioning hole 210 cooperates with the through hole 121. The first relief region 153 and the second relief region 154 are respectively provided on both sides of the intermediate region 152. The first relief region 153 can be close to the light emission outlet 110, and the second relief region 154 can be far from the light emission outlet 110. The first relief region 153 and the second relief region 154 are used to prevent the third side plate 140 or the fourth side plate 150 from interfering with the light dimming plate 200 when the light dimming plate 200 rotates.

[0063] In some examples, the light dimming plate 200 can be rotated until the second end of the light dimming plate 200 contacts the third side plate 140 or the fourth side plate 150, and the third side plate 140 or the fourth side plate 150 can play a role in limiting the extreme position.

[0064] In some examples, the second end of the light dimming plate 200 is provided with a convex block 230 protruding from the main body of the light dimming plate 200 to the side away from the light emission outlet 110. The convex block 230 facilitates a person to grasp the second end of the light dimming plate 200 to swing the light dimming plate 200.

[0065] In some examples, the outer ends of the third side plate 140 and the fourth side plate 150 are provided with an uneven structure 155, and the uneven structure 155 can increase the friction force and facilitate a person to grasp the housing.

[0066] In some examples, the housing 100 has at least two light emission outlets 110. Each light emission outlet 110 is respectively matched with at least two corresponding light dimming plates 200, and the light dimming plates 200 corresponding to each light emission outlet 110 can be independently movable. That is, the lamp in this embodiment can have multiple light output ports, and the size and direction of each light output port can be adjusted, and the light output effect is more abundant, which is suitable for application scenarios that require multi-directional light output.

[0067] In some examples, the housing 100 has two light-emitting outlets 110 arranged opposite to each other. The housing 100 further includes a support plate 190 and a receiving cavity 161 surrounded by a surrounding plate 160 on the support plate 190. Among them, the support plate 190 can be the same plate as the second side plate 120, or the two are integrally formed, or the two are connected to each other, as long as the second side plate 120 is located on the support plate 190. The light-emitting outlet 110 is located on the support plate 190, and the receiving cavity 161 is arranged between the two light-emitting outlets 110. The receiving cavity 161 has a first opening away from the support plate 190. The receiving cavity 161 can be used to place devices such as the LED lamp of the light-emitting module or the LED lamp and its electronic control device and wires.

[0068] In some examples, the surrounding plate 160 is bent to form at least one positioning groove 162, and the positioning groove 162 is used for fixedly connecting with the light-emitting module. The surrounding plate 160 directly forms the positioning groove 162, which can simplify the structure.

[0069] In some examples, the surrounding plate 160 is bent to form at least one reinforcing structure 163. The reinforcing structure 163 can be, for example, a structure protruding outward, which can prevent the surrounding plate 160 from deforming under pressure and improve the mechanical strength.

[0070] In some examples, a clamping groove 170 is further provided on the support plate 190. The clamping groove 170 has a second opening away from the support plate 190, and a clamping block 171 is arranged in the clamping groove 170. The clamping groove 170 can be used for positioning the light-emitting module, facilitating the fixing of the light-emitting module. For example, it facilitates the subsequent fixed connection between the light-emitting module and the positioning groove 162.

[0071] In some examples, the clamping groove 170 is arranged outside the receiving cavity 161, which is more conducive to intuitive positioning.

[0072] In some examples, at the movable connection between the dimming plate 200 and the housing 100, the housing 100 is provided with a positioning and installation opening corresponding to each dimming plate 200 and away from the support plate 190. The positioning and installation opening can be a through hole 121. Clamping grooves 170 are respectively arranged on both sides of all the positioning and installation openings corresponding to the same light-emitting outlet 110 for clamping on both sides of the through hole 121.

[0073] In some examples, the LED lamp fixture can further include a light-emitting component (not shown in the figure). The light-emitting component includes a cover plate and at least two LED lamps arranged on the cover plate. The LED lamps can be light strips or lamp beads. The LED lamps extend into the receiving cavity 161 and correspond to the light-emitting outlets 110 one by one, and the LED lamps can be attached to the light-emitting outlets 110.

[0074] In some examples, the cover plate of the light-emitting component is adjacent to the surrounding plate 160 and covers the side of the surrounding plate 160 away from the support plate 190. Some devices of the light-emitting component can be placed in the accommodation cavity 161. The cover plate is connected to the positioning groove 162 through a fastener, and the fastener can be, for example, a threaded fastener, to realize the connection between the light-emitting component and the housing 100.

[0075] In some examples, the cover plate is snap-connected to the clamping block 171. For example, the cover plate can be provided with a snap or a clamping claw, and the snap or the clamping claw extends into the clamping groove 170 and cooperates with the clamping block 171 to realize the positioning of the cover plate, which is convenient for the cover plate to be further fixedly connected to the positioning groove 162.

[0076] In some examples, the cover plate covers the positioning installation opening or the through hole 121, and the cover plate can protect the connecting piece such as a rotating shaft at the positioning installation opening or the through hole 121 to prevent the connecting piece from coming out.

[0077] In some examples, the housing 100 further includes a wall plate 180 provided around the support plate 190 and perpendicular to the support plate 190. The light-emitting outlet 110 and the light-dimming plate 200 are located in the space surrounded by the wall plate 180. At least two third openings are provided on the wall plate 180, and each third opening corresponds to each light-emitting outlet 110. The third opening can be formed by enclosing the ends of the first side plate 120, the second side plate 130, the third side plate 140, and the fourth side plate 150, and the light-dimming plate 200 further defines a light outlet in the third opening.

[0078] In some examples, the edge of the wall plate 180 away from the support plate 190 is flush with the surface of the cover plate away from the support plate 190, or the edge of the wall plate 180 away from the support plate 190 is farther away from the support plate 190 than the surface of the cover plate away from the support plate 190, so as to prevent the light-emitting component from protruding from the housing 100, which is convenient for the installation, stacking, etc. of the lamp.

[0079] In some examples, the projection of the housing 100 on the support plate 190 is rectangular or square, and the shape of the housing 100 is regular, which is beneficial to the installation, stacking, etc. of the lamp.

[0080] Finally, it should be emphasized that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
