[0022] Hereinafter are only preferred embodiments of the present invention, which are only used to facilitate the understanding of the present invention rather than tolimit the structure of the embodiments mentioned above. Based on the embodiments of the present invention, all the other embodiments obtained by the skilled in the art being capable of achieving the effect of the present invention are within the protection scope of the present invention. 5 Embodiment 1
[0023] With reference to figures1-3, the present invention discloses a LED lamp with animated effect, which comprises a lamp head and a supporting portion. The lamp head is connected to the supporting portion via a rotating device 17. The lamp head comprises a lampshell 16 and two assembled units of imaging lens. Each of the assembled unit of imaging lens comprises a convex lens assembly 3, a film 8 and a LED 12. The convex lens assembly 3 has short focal length and large thickness. A convex surface of the convex lens assembly 3 is set facing the film 8. The convex lens assembly 3 comprises a first convex lens 31 and a second convex lens 32. The first convex lens 31, the film 8, the second convex lens 32 and the LED 12 are lined up in the lampshell 16 in order. The film 8 is placed between f (stands for focal length of convex lens in this specification) and 2f of the first convex lens 31. The LED 12 is placed at the 2f point of the second convex lens 32. A third convex lens 33 is disposed between the second convex lens 32 and the LED 12 while the LED 12 is placed between f and 2f of the third convex lens 33. The first convex lens 31, the second convex lens 32 and the third convex lens 33 are parallel to each other. The first convex lens 31 is fixedly installed in the lamp head via a first fastener 5; the second convex lens 32 is fixedly installed in the lamp head via a presser 9; and the third convex lens 33 is fixedly installed in the lamp head via a second fastener 11. The lamp is able to promote the clarity and area of displayed images through placing the third convex lens 33 between the second convex lens 32 and the LED 12.
[0024] The LED 12 is configured on the aluminum substrate 13, wherein the aluminum substrate 13 is fixedly installed in the lamp head via an aluminum substrate fastener 10. The LEDs 12 in the two assembled units of imaging lens could have same color or different colors. A front cover 4 is configured on a side of the lamp head that is near the first convex lens 31. The front cover 4 is fixedly installed in the lamp headvia bolts. The lamp is applicable both indoors and outdoors since a side of the front cover 4 that is near the convex lens 3 is provided with a first seal ring 1; and a flat surface of the first convex lens 31 is provided with a second seal ring 2. The film 8 is fixedly installed in the lamp head via a film pin 6 while the film pin 6 is provided with aretaining cap 7. Patterns are configured on the film 8. The patterns could be unicolor or chromatic; the patterns could be simulating fireworks displayed in the sky, eagles outspreading wings, butterflies dancing, rabbits jumping, flowers blooming, cartoon characters dancing and etc.. The supporting portion comprises a first supporting member 18 and a second supporting member 19. The first supporting member 18 is connected to the rotating device 17, and the first supporting member 18 is moveably connected to the second supporting member 19. The LED 12 is electrically connected to a circuit board 14. The circuit board 14 is fixedly installed in the lamp head via a third fastener 15. The circuit board 14 is configured and programmed with multiple integrated circuits. The circuit board 14 controls the LED 12 in the multiple assembled units of imaging lens to shine in different ways, therefore various animated patterns are able to display on the film 8. A contact surface of the rotating device 17 and the lampshell 16 is ladder-shaped while the lampshell 16 is half ellipsoid. Embodiment 2
[0025] With reference to figures 4-5, the difference between the present embodiment and embodiment 1 is that the lamp head in this embodiment comprises three assembled units of imaging lens. The LEDs 12 in the three assembled units of imaging lens could have same color or different colors. A contact surface of the rotating device 17 and the lampshell 16 is L-shaped. The rotating device 17 is engaged with the lampshell 16 via a fixing device 20. The lampshell 16 has the structure of a polygonal cylinder. Embodiment 3
[0026] With reference to figure 6, the difference between the present embodiment and embodiment 1 is that the lamp head in this embodiment comprises four assembled units of imaging lens. The LEDs 12 in the three assembled units of imaging lens could have same color or different colors. A contact surface of the rotating device 17 and thelampshell 16 is reversed U-shaped. The lampshell 16 is a cylinder.
[0026] The present invention also discloses an imaging principle of an assembled unit of imaging lens of a LED lamp with animated effect. Figure 7 is a schematic diagram of imaging of the assembled unit of imaging lens of the LED lamp shown in the present invention. As shown in figure 7, when the LED 12 is turned on, the light goes through the second convex lens 32 and the third convex lens 33 to be gathered therefore the luminance of the light is enhanced. Gathered light shines on the film 8 and enlarges the images when the light goes through the first convex lens 31, therefore the clarity and area of displayed images is enhanced.
[0027] The above-mentioned embodiments are the preferred embodiments of the present invention. Variations and modifications are allowed within the scope of the invention. Those skilled in the art will appreciate that the features described above can be combined in various ways to form multiple variations of the invention. As a result, such variations fall within the scope of the protection of the present invention.
