Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-6 , the present utility model provides a technical solution: a lens assembly of a dial-type light spot-adjustable projection lamp, including a projection lamp body 1, a light source 5 is provided at the projection end of the projection lamp body 1, the light source 5 is an LED lamp bead, a light projection sheet 7 is connected to the projection end of the projection lamp body 1, a convex lens 8 is integrally provided on the light projection sheet 7, the light source 5 is located at the focal point of the convex lens 8. When the light source 5 is powered on and emits light, under the action of the convex lens 8, the light of the light source 5 can be emitted parallelly to achieve concentrated light projection. A light-changing sleeve 10 is also connected to the projection end of the projection lamp body 1, a light-changing sheet 12 is rotatably connected inside the light-changing sleeve 10, and glass 13 and a soft light plate 14 arranged at equal intervals in a ring shape are provided on the light-changing sheet 12. When the light-changing sheet 12 rotates, the positions of the glass 13 and the soft light plate 14 correspond to the position of the light source 5 in sequence;

[0031] During specific use: By turning the light-changing sheet 12, the glass 13 on the light-changing sheet 12 is made to correspond to the light source 5. When the light source 5 emits light, under the action of the convex lens 8, the light of the light source 5 can pass through the glass 13 and be emitted parallelly, realizing concentrated light projection, and then forming a hard light spot around the object; when the light-changing sheet 12 is turned so that the soft light plate 14 corresponds to the light source 5, the light of the light source 5 passes through the soft light plate 14 and is emitted parallelly under the action of the convex lens 8, thereby forming a soft light spot around the object, so as to realize the mutual adjustability of hard light and soft light, so that users can use it according to actual needs, and the practicability is better;

[0032] Furthermore, since the light source 5 will generate relatively high heat during long-term operation, after a long time, the light projection sheet 7 and the integrally connected convex lens 8 will be deformed or damaged, thereby affecting the light projection. Therefore, a rotating card slot 6 can be opened on the inner wall of the projection end of the projection lamp body 1. The rotating card slot 6 is in an "L" shape, and one end of it extends to the opening of the projection end of the projection lamp body 1. A card block 9 adapted to the size of the rotating card slot 6 is arranged on the edge of the light projection sheet 7. A rubber pad is adhered to the surface of the card block 9. The light projection sheet 7 is snap-connected to the projection end of the projection lamp body 1 through the cooperation of the rotating card slot 6 and the card block 9. At the same time, a mutually matching thread structure is opened on the inner wall of the projection end of the projection lamp body 1 and the edge of the light-changing sleeve 10, so that a threaded connection is formed between the projection end of the projection lamp body 1 and the light-changing sleeve 10;

[0033] During specific use: By rotating the light-changing sleeve 10, the light-changing sleeve 10 can be disassembled from the projection end of the projection lamp body 1. Secondly, by rotating the light projection sheet 7, the card block 9 is rotated to the opening of the rotating card slot 6 and the projection end of the projection lamp body 1, and then the projection lamp body 1 is inverted, and the light projection sheet 7 can be disassembled. Furthermore, when the light projection sheet 7 is deformed or damaged, the light projection sheet 7 can be replaced separately, which is convenient for maintenance and repair, and thus the use cost of users can be reduced; when replacing a new light projection sheet 7, just operate in reverse according to the above steps;

[0034] Furthermore, since the light-changing sheet 12 is rotationally connected to the light-changing sleeve 10, the light-changing sheet 12 is prone to self-rotation under the influence of external force, which will cause the light spot to be automatically adjusted and affect the use. Therefore, a limiting groove 11 can be opened on the inner wall of the light-changing sleeve 10, and a spring 15 is arranged inside the light-changing sheet 12. One end of the spring 15 is connected to a clamping bead 16, and a part of the clamping bead 16 extends out of the light-changing sheet 12. The clamping bead 16 forms an elastic structure with the light-changing sheet 12 through the spring 15, and the position and size of the exposed part of the clamping bead 16 are adapted to the position and size of the limiting groove 11. The light-changing sheet 12 forms a rotational snap connection with the light-changing sleeve 10 through the limiting groove 11, the spring 15 and the clamping bead 16;

[0035] During specific use: When the light-changing plate 12 is rotated, under the action of the spring 15, the clamping beads 16 can be clamped into the interior of the limiting groove 11, thereby forming a clamping engagement to play a limiting role, so that the light-changing plate 12 is fixed after rotation, effectively reducing the influence of external force on the light-changing plate 12 and preventing the light-changing plate 12 from self-rotating.

[0036] Furthermore, fastening holes 4 are provided on both sides of the projection lamp body 1. A support frame 2 is arranged between the two fastening holes 4. Through holes adapted to the two fastening holes 4 are respectively provided at both ends of the support frame 2. By inserting a fastener 3, that is, a bolt, into the through hole and threadedly connecting it with the fastening hole 4, the connection and fixation between the support frame 2 and the projection lamp body 1 can be achieved.

[0037] During specific use: Through the installation of the support frame 2, the projection lamp body 1 can be installed on other objects, such as walls, floors, etc. At the same time, by utilizing the locking torque between the fastener 3 and the fastening hole 4, the angle adjustment of the projection lamp body 1 on the support frame 2 can be achieved to facilitate user use, as Figure 7 shown.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
