The projection lamp with the structure can be adapted to the variable light sheets 400 with different thickness specifications, and the universality of the projection lamp is improved.

It will be appreciated that in some cases, the light-changing sheet 400 need not be installed, and in this case, the light projector may not be installed with the light-changing sheet 400.

In the embodiment shown in the drawings, the direction approaching and separating from the light emitting portion is shown by a double arrow a in the drawings, and the direction is the direction in which the position of the limiting frame 200 is adjusted.

In an embodiment, the limiting frame 200 is slidably disposed on the lamp body 100 along the direction of the adjusting position of the limiting frame 200, the limiting frame 200 includes a main frame 220 and an elastic arm 230 extending along the direction of the adjusting position of the limiting frame 200, one end of the elastic arm 230 is connected with the main frame 220, three clamping gears 231 are arranged on the elastic arm 230 along the direction of the adjusting position of the limiting frame 200, the lamp body 100 is provided with a clamping portion 110, the clamping portion 110 can be clamped in different clamping gears 231, and when the limiting frame 200 slides, the elastic arm 230 can elastically deform around one end of the elastic arm and enable the clamping portion 110 to be matched with the different clamping gears 231. When the position of the limiting frame 200 needs to be adjusted, a user forcefully moves the limiting frame 200, so that the elastic arm 230 of the limiting frame 200 elastically deforms, the clamping part 110 is separated from the clamping gear 231, and then the clamping part 110 is clamped with the adjacent clamping gear 231; the above process is repeated until the clamping portion 110 is clamped in the appropriate clamping gear 231. The structure of the limiting frame 200 realizes the function of adjusting the position of the limiting frame 200 relative to the lamp body 100, and has simple structure and easy implementation. It is conceivable that the number of the engagement steps 231 may be other numbers, for example, two or more engagement steps 231 are arranged in the direction in which the stopper 200 is adjusted.

In the embodiment, the elastic arms 230 are arranged along the position adjusting direction of the limiting frame 200 to form the clamping gear 231, the clamping portion 110 is a clamping block, and the clamping groove is adapted to the clamping block, so that the structure is simple and implementation is easy. It is understood that the clamping gear 231 may also be a clamping block, and the corresponding clamping portion 110 is a clamping groove.

In an embodiment, the notch of the clamping groove faces the direction of the adjusting position of the vertical limiting frame 200, and the clamping block is a conical block facing the notch. The clamping block is a conical block and is conveniently abutted with the periphery of the notch of the clamping groove, so that the elastic arm 230 elastically deforms, the clamping part 110 is separated from the clamping groove, and then the elastic arm 230 resets and the clamping part 110 enters another clamping groove. With the above structure, when the limiting frame 200 is moved, the locking portion 110 is automatically separated from the locking gear 231.

It is conceivable that the clamping groove is also provided as a conical groove.

In an embodiment, the elastic arm 230 is an integrally injection molded structure with the main frame 220. The above-mentioned spacing frame 200, because of the elasticity of the plastic itself, makes the elastic arm 230 swing relative to the main frame 220 by elastic deformation, and the elastic arm 230 can automatically reset to make the clamping portion 110 and the clamping gear 231 clamped, so that the structure is smart, and the production and the manufacturing are relatively convenient.

It is conceivable that other structures are also possible to make the elastic arm 230 elastic and capable of swinging, for example, one end of the elastic arm 230 is pivotally connected to the main frame 220, and a spring is provided between the lamp body 100 and the elastic arm 230, and applies a force of the elastic arm 230 toward the clamping portion 110. In a normal state, the spring makes the clamping gear 231 on the elastic arm 230 clamped with the clamping portion 110. When the limiting frame 200 is moved, the spring stores elastic potential energy, the clamping gear 231 of the elastic arm 230 is separated from the clamping portion 110, then the elastic arm 230 is reset, and the other clamping gear 231 is clamped with the clamping portion 110, so that the position of the limiting frame 200 relative to the lamp body 100 is adjusted.

Specifically, the lamp body 100 is provided with a receiving hole 240, and the limiting frame 200 is disposed through the receiving hole 240, so that the limiting frame 200 can slide relative to the lamp body 100. It is conceivable that a guide post is further disposed on the lamp body 100, a guide hole is disposed on the limiting frame 200, and the guide post is disposed through the guide hole, so that the limiting frame 200 can slide relative to the lamp body 100, and cooperate with the elastic arm 230 and the clamping portion 110 to adjust the position.

In an embodiment, the light-changing sheet 400 is further included, and the light-changing sheet 400 is disposed at the light-changing sheet mounting location 300. The light-changing piece 400 is arranged, so that the projection lamp can conveniently project light rays with specific light spot shapes. In the field of lamp decoration, the light-changing sheet 400 is a composite structure of glass and aluminum plate, and the light-changing sheet 400 is a conventional accessory, and will not be described here.

In an embodiment, the limiting frame 200 is detachably connected to the lamp body 100. The limiting frame 200 can be detached, so that the light-changing sheet 400 can be conveniently installed, detached or replaced according to the needs, and the universality of the projection lamp is good. Specifically, when the limiting frame 200 moves to the limit position along the direction of the adjusting position of the limiting frame 200, the elastic arm 230 of the limiting frame 200 starts to separate from the clamping portion 110, and finally the limiting frame 200 is completely separated from the lamp body 100, so that the limiting frame 200 is disassembled. When the limit frame 200 needs to be mounted, the limit frame 200 is inserted into the lamp body 100, and at this time, the clamping gear 231 of the elastic arm 230 is clamped with the clamping portion 110 again.

In the embodiment, the lamp body 100 is provided with a lamp panel 120, the light emitting portion is a lens 130, the lens 130 is covered on the lamp panel 120, the limiting frame 200 is provided with a containing hole 240, one side of the lens 130 away from the lamp panel 120 is contained in the containing hole 240, and the lens 130 and the wall of the containing hole 240 enclose to form a light conversion piece mounting position 300. The lens 130 and the limiting frame 200 are used for clamping the light-changing sheet 400, so that the light-transmitting effect is good, and the light utilization efficiency is high. It should be understood that, when the lamp body 100 is not provided with the lens 130, other portions of the lamp body 100 and the limiting frame 200 may clamp the light-changing sheet 400 together.

Specifically, the light panel 120 may be an LED light panel 120 or a common light panel 120, and the lens 130 may be a convex lens 130.

In some embodiments, the stopper 200 is provided with an antiglare cylinder 250 extending in a direction in which the stopper 200 adjusts a position, and the antiglare cylinder 250 is disposed around the light outlet 210. The antiglare barrel 250 is provided to reduce light pollution, protect eyes of an observer, and reduce glare.

Specifically, the length of the antiglare tube 250 has an influence on the light shielding angle. When the antiglare barrel 250 is longer, the angle of extinction is larger, the size of the light spot is smaller, and the antiglare effect is better. When the antiglare cylinder 250 is short, the light shielding angle is small, and the size of the flare is relatively large. In some embodiments, the antiglare tube 250 may not be provided.

In the embodiment, the hole wall of the light emitting hole 210 is provided with a plurality of steps in a direction of adjusting the position of the limiting frame 200. The multiple steps are arranged, so that stray light can be reduced, and the anti-dazzle effect is enhanced. Specifically, the number of steps may be three or more, and those skilled in the art may specifically configure the steps according to actual needs.
