DESCRIPTION OF EMBODIMENTS

(8) In order to render the above objectives, features, and advantages of the present application more obvious and understandable, a detailed explanation of the specific implementation of the present application will be provided below in combination with the accompanying drawings. Many specific details are elaborated in the following description to facilitate a thorough understanding of the present application. However, the present application can be implemented in many different ways from the described herein, and those skilled in the art can make similar improvements without departing from the scope of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

Embodiment 1

(9) In this embodiment of the present application, as shown in FIGS. 1-5, a dynamic lunar eclipse lamp is provided, which includes a blocking piece 1. The blocking piece 1 includes a transparent area 102 and a circular opaque area 101, the opaque area 101 is provided at a non-central position of the blocking piece 1.

(10) The dynamic lunar eclipse lamp further includes an imaging lens 2, the imaging lens 2 is provided on one side of the blocking piece 1. One end of the imaging lens 2 is provided with a Fresnel lens 4 configured to image, and an image is provided at a non-central position on the Fresnel lens 4. The imaging lens 2 is configured to project the image onto a non-central position on the blocking piece 1, and a position of the image projected by the imaging lens 2 corresponds to a position of the opaque area 101 on the blocking piece 1.

(11) The dynamic lunar eclipse lamp further includes a rotary drive component, which is connected to the Fresnel lens 4. The rotary drive component is configured to drive the Fresnel lens 4 to rotate. The rotary drive component can be implemented by a gear transmission, a belt transmission, or screw transmission; and the dynamic lunar eclipse lamp further includes a light source component configured to project a light spot onto the Fresnel lens 4.

(12) On the Fresnel lens 4, an image containing a moon is provided. When the rotary drive component drives the Fresnel lens 4 to rotate, the moon image on it can be moved around because it is at the non-central position. Through the imaging lens 2, the moon image can be moved around a center of the blocking piece 1. Since the position of the image projected by the imaging lens 2 corresponds to the position of the opaque area 101 on the blocking piece 1, the moon image can overlap with the opaque area 101 during rotation. When the moon image completely overlaps with the opaque area 101, it is completely blocked, thereby forming a lunar eclipse effect. When the moon image partially overlaps with the opaque area 101, it can form a crescent or a half-moon display effect. This effect is also constantly changed due to a driving of the rotary drive component, thus achieving a dynamic lunar eclipse display effect, rendering the display effect vivid, and satisfying people's growing personalized needs.

(13) The rotary drive component includes a gear plate 3, and the gear plate 3 is rotatably connected to a bracket 12, the gear plate 3 is connected to a motor 9 through gear transmission. The Fresnel lens 4 is fixed on the gear plate 3 through a fixing ring 5, and the motor 9 drives the gear plate 3 to rotate through the gear transmission, which in turn drives the Fresnel lens 4 to rotate, thus achieving a rotation of the lunar image. The Fresnel lens 4 is lightweight and has small size, so driving the Fresnel lens 4 to rotate further reduces energy consumption.

(14) There is a through hole in a middle of the gear plate 3, and Fresnel lens 4 is fixed at a position of the through hole. The Fresnel lens 4 is located at a middle of the gear plate 3, and the Fresnel lens 4 is more stable.

(15) One side of the gear plate 3 is meshed and connected with a reduction gear 11, and the reduction gear 11 includes a small diameter gear and a large diameter gear with a coaxial integrated structure. The small diameter gear is meshed with the gear plate 3, and the large diameter gear is meshed with a transmission gear 10; the transmission gear 10 is connected to an output shaft of the motor 9. By the reduction gear 11 and the transmission gear 10, the motor 9 can stably drive the gear plate 3 to rotate, with smooth transmission, compact structure, reliable operation, and long service life.

(16) The light source component includes a spotlight lens 6, and the spotlight lens 6 is located on one side of the Fresnel lens 4. One side of the spotlight lens 6 is provided with a lamp bead 8, and the lamp bead 8 uses 3535 white light beads. The spotlight lens 6 is configured to gather light from the lamp bead 8 and project it onto the Fresnel lens 4, thereby forming a circular spot with a diameter of 11 mm on the Fresnel lens 4.

(17) One side of the spotlight lens 6 is provided with a spotlight cup 7, and the lamp bead 8 is provided in a middle of the spotlight cup 7. The spotlight cup 7 is configured to gather the light from the lamp bead 8 and project gathered light onto the spotlight lens 6. The spotlight lens 6 and the spotlight cup 7 are cooperated to perform a second focusing, which can form a more stable spot effect.

(18) The lamp bead 8 is fixedly installed on an aluminum substrate 13, and the aluminum substrate 13 is configured to carry the lamp bead 8 and help dissipate heat from the lamp bead 8.

Embodiment 2

(19) Embodiment 2 is an improvement based on Embodiment 1. In order to achieve higher brightness, there are a plurality of lamp beads 8 in this embodiment of the present application, and the lamp beads 8 are distributed around a center of the spotlight cup 7. There are three lamp beads 8, and the number of the lamp beads 8 is not limited. They can be set according to needs. More lamp beads 8 produce higher brightness or fewer lamp beads 8 are more energy-efficient, and the surrounding distribution renders the light more uniform.

(20) Working principle: the light source is emitted from the lamp bead 8 and is first focused by the spotlight cup 7. After reducing the angle of the light source, the light passes through the spotlight lens 6 for a second focusing. After the second focusing, the light is focused by the spotlight lens 6 onto the Fresnel lens 4, thereby forming a circular spot on the Fresnel lens 4. Then, the spot illuminates the lunar image on the Fresnel lens 4, passes through the imaging lens 2, and finally projects the lunar image on the Fresnel lens 4 onto the blocking piece 1.

(21) During the process, the motor 9 can drive the Fresnel lens 4 to rotate through the gear plate 3. The moon image on the Fresnel lens 4 is at the non-central position and is moved around the center of the blocking piece 1 through the imaging lens 2. Since the position of the image projected by the imaging lens 2 corresponds to the position of the opaque area 101 on the blocking piece 1, the moon image can overlap with the opaque area 101 during rotation. When the moon image completely overlaps with the opaque area 101, it is completely occluded, thereby forming a lunar eclipse effect. When the moon image partially overlaps with the opaque area 101, it can form a crescent or a half-moon display effect. This effect also be continuously changed due to the driving of the rotary drive component, thus achieving a dynamic lunar eclipse display effect.

(22) The above is only preferred embodiments of the present application and does not limit the present application in any form. Those skilled in the art may use the methods and technical content disclosed above to make many possible changes and modifications to the technical solution of the present application, or modify it into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of the present application. Therefore, any equivalent changes made based on the shape, structure, and principle of the present application that do not deviate from the technical solution of the present application should be covered within the protection scope of the present application.
