[0045] The present application will be further described in detail below in combination with the drawings and the specific embodiments. EMBODIMENTS

[0046] As Figs. 1 to 7 shown, the embodiment provides a LED lamp with adjustable light outlet size and direction, which comprises a shell 100 and a light adjusting plate 200.

[0047] The shell 100 has a light outlet 110 for the light of the LED lamp to emit from, and the light outlet 110 can also be the mounting position of the LED lamp.

[0048] The number of the light adjusting plates 200 is at least two, and the plurality of light adjusting plates 200 are arranged staggered around the light outlet 110, so that the plurality of light adjusting plates 200 respectively guide and constrain the light on different sides of the light outlet 110. The light adjusting plates 200 extend outward relative to the light outlet 110, so as to guide and constrain the light emitted from the light outlet 110. The first end of each light adjusting plate 200 is independently movably connected with the shell 100, that is, each light adjusting plate 200 is connected with the shell 100 and can independently move relative to the shell 100 at the connection without affecting each other, and the movement can include moving or rotating, so that the angle between the extension direction of each light adjusting plate 200 and the normal direction of the light outlet 110 is independently adjustable, so that the second ends of the at least two light adjusting plates 200 can be close to or away from each other.

[0049] In the embodiment, the first end of the light adjusting plate 200 can independently move relative to the shell 100, so that the angle between the extension direction of the light adjusting plate 200 and the normal direction of the light outlet 110 can be independently adjusted, so as to adjust the direction of the light outlet, and the second end of the light adjusting plate 200 constitutes part of the light outlet, and the second end of the light adjusting plate 200 can be close to or away from each other to adjust the size of the light outlet. The extension direction of the light adjusting plate 200 refers to the direction of the plate itself, and the normal direction of the light outlet 110 refers to the vertical direction of the plane where the light outlet 110 is located. For example, the light adjusting plates 200 are respectively arranged on both sides of a light outlet 110, and when the light adjusting plates 200 on both sides move synchronously, the light direction of the light outlet can be changed; when the light adjusting plates 200 on both sides move towards each other, the light outlet can be made smaller; and when the light adjusting plates 200 on both sides move away from each other, the light outlet can be made larger. When adjusting the light adjusting plate 200, only one light adjusting plate 200 can be adjusted while keeping the other light adjusting plate 200 unchanged, or multiple light adjusting plates 200 can be adjusted at the same time. The adjustment of the light adjusting plate 200 can be manual or electric. It can be seen that the LED lamp of the embodiment can flexibly adjust the size and direction of the light outlet, can enrich the light effect of the LED lamp, and improve the application flexibility of the LED lamp.

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

[0051] In some examples, the shell 100 includes a first side plate 120 and a second side plate 130, which are oppositely arranged in a first direction perpendicular to the normal direction of the light emitting port 110 and extend outward from two opposite sides of the light emitting port 110. The light adjusting plate 200 is arranged between the first side plate 120 and the second side plate 130, and the first ends of the two light adjusting plates 200 are oppositely arranged in a second direction perpendicular to the normal direction of the light emitting port 110. 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 light adjusting plates 200 together form a light emitting port, so that the structure of the light emitting port is more regular, and the adjustment of the light adjusting plate 200 is more convenient and easy to control.

[0052] In some examples, the first end of the light adjusting plate 200 is rotatably arranged between the first side plate 120 and the second side plate 130, at least one of the first side plate 120 and the second side plate 130 can serve as a support for the light adjusting plate 200, and the light adjusting plate 200 is connected to the shell in a rotating manner, so that the adjustment of the light adjusting plate 200 is more convenient and easy to control.

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

[0054] In some examples, the first side plate 120 is provided with a through hole 121 extending through the first side plate 120 in the first direction, and the first end of the light adjusting plate 200 is provided with a positioning hole 210 extending in 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 rotating shaft realizes the rotating connection of the first side plate 120 and the light adjusting plate 200. The rotating shaft can be in transition fit or clearance fit with the light adjusting plate 200, and the rotating shaft can be in interference fit or fixed connection with the through hole 121, so that the light adjusting plate 200 can rotate relative to the rotating shaft to realize angle adjustment. Preferably, the light adjusting plate 200 needs to rotate relative to the rotating shaft under certain force, and remain stationary relative to the rotating shaft when not under force, so as to avoid shaking or undesirable movement of the light adjusting plate 200.

[0055] In some examples, the first side of the first side plate 120 close to the second side plate 130 is provided with a boss 122, and 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. The first end of the light adjusting plate 200 is provided with a retracted portion 220 matched with the boss 122, and the positioning hole 210 is open to the retracted portion 220. By matching the retracted portion 220 with the boss 122, the light adjusting plate 200 and the first side plate 120 can be accurately positioned, and the light adjusting plate 200 and the first side plate 120 can be closely connected to avoid light leakage.

[0056] In some examples, the second side of the first side plate 120 away from the second side plate 130 is provided with a counterbore 123, and the through hole 121 passes through or is open 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 is open to the outside of the shell 100, which is convenient for installing 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 ray outlet 110, and the first side plate 120 and the second side plate 130 are parallel to each other. The two sides of the light adjusting plate 200 can be parallel straight lines, so that the matching structure between the light adjusting plate 200 and the first side plate 120 and the second side plate 130 is more regular and simple.

[0059] In some examples, the shell 100 further includes a third side plate 140 and a fourth side plate 150 arranged 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 ray outlet 110. The light adjusting plate 200 is located between the third side plate 140 and the fourth side plate 150, and the third side plate 140 and the fourth side plate 150 can limit the movement area of the light adjusting 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 ray outlet 110, providing a range for the movement of the light adjusting 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 ray outlet 110, reducing the area of the light outlet channel and avoiding dust accumulation.

[0061] In some examples, the third side plate 140 and the fourth side plate 150 are respectively provided with a recessed portion 151 close to the light exit 110, the first end of the light adjusting plate 200 is provided with a movable connection portion bent relative to the main body of the light adjusting plate 200, the positioning hole 210 can be arranged on the movable connection portion, the movable connection portion at least partially extends into the recessed portion 151 and is movably connected with the shell 100, so that the light is not directly leaked out from the gap between the third side plate 140 or the fourth side plate 150 and the first end of the light adjusting plate 200, and meanwhile the first end of the light adjusting plate 200 is also reduced to block the light in the light propagation path.

[0062] In some examples, the recessed portion 151 includes a middle region 152, a first accommodation region 153 and a second accommodation region 154, the middle region 152 can be arranged corresponding to the through hole 121, the movable connection portion at least partially extends into the middle region 152, so that the positioning hole 210 cooperates with the through hole 121, the first accommodation region 153 and the second accommodation region 154 are respectively arranged on both sides of the middle region 152, the first accommodation region 153 can be close to the light exit 110, and the second accommodation region 154 can be away from the light exit 110, the first accommodation region 153 and the second accommodation region 154 are used to avoid the third side plate 140 or the fourth side plate 150 interfering with the light adjusting plate 200 when the light adjusting plate 200 rotates.

[0063] In some examples, the light adjusting plate 200 can be rotated to the second end of the light adjusting plate 200 being in contact with 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 limiting role of the limit position.

[0064] In some examples, the second end of the light adjusting plate 200 is provided with a protrusion 230 protruding relative to the main body of the light adjusting plate 200 to the side away from the light exit 110, the protrusion 230 facilitates a hand of a person to hold the second end of the light adjusting plate 200 to swing the light adjusting plate 200.
