Problems solved by technology
[0002] Existing LED lamp beads are often used as decorations for hanging decoration. Because the focal length of the hanging decoration is not variable, the decoration effect is single, and the decoration effect is not good. Therefore, a This kind of lamp beads can show more light effects when hanging decoration, and increase its decorative characteristics

The invention discloses an LED lamp bead with an adjustable focal length, and relates to the technical field of LED lamp beads. The focal length adjustable LED lamp bead comprises a fixing ring, an LED lamp panel is arranged in the fixing ring, the outer wall of the fixing ring is in threaded connection with an external ring, an air cavity is formed in the external ring, the upper side, the lower side and the interior of the external ring are communicated through the air cavity, the upper side of the external ring is fixedly connected with a convex lens, and a moving mechanism is arranged in the fixing ring. According to the focal length adjustable LED lamp bead, when the focal length adjustable LED lamp bead is used, the LED lamp panel is connected with an external circuit, the convex lens is downwards hung, due to the fact that the LED lamp panel can generate heat when working, gas in a gas storage mechanism is expanded, a connecting ring can move, the convex lens drives the external ring to rotate and move, and therefore the distance between the convex lens and the LED lamp panel is changed; the focal length is automatically changed, and the effect of changing the lighting effect is achieved.
Description
technical field [0001] The invention relates to the technical field of LED lamp beads, in particular to an LED lamp bead with adjustable focal length. Background technique [0002] Existing LED lamp beads are often used as decorations for hanging decoration. Because the focal length of the hanging decoration is not variable, the decoration effect is single, and the decoration effect is not good. Therefore, a This kind of lamp beads can show more light effects when hanging decoration, and increase its decorative characteristics. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides an LED lamp bead with adjustable focal length, so as to achieve the purpose of presenting more light effects during hanging decoration. [0004] In order to achieve the above purpose, the present invention is achieved through the following technical solutions: an LED lamp bead with adjustable focal length, including a fixed ring, an LED la...
