Abstract
Description
Technical Field
[0001] The invention relates to the field of lighting equipment, and in particular to a lamp focusing structure. Background Art
[0002] The principle of focusing lamps in the prior art is that the LED light source is fixed on a cylindrical lamp body and cannot be moved. The axial distance between a single or multiple convex lenses and the LED light source is adjusted to adjust the light spot size and beam angle. However, the problem with the prior art is that it cannot form an image and does not produce the lighting effect required. At present, most of the focusing structures of lamps imitate the focusing of camera lenses. Generally, the focusing method of camera lenses is to change the distance between the optical center of the lens and the film plane in order to obtain a clear image. The disadvantage is that there are many spare parts, and the processing accuracy and assembly requirements are very high. The cost is very high and it is not suitable for mass production. Summary of the invention
[0003] In view of the deficiencies in the prior art, the present invention discloses a lamp focusing structure.
[0004] The technical solution adopted by the present invention is as follows:
[0005] A lamp focusing structure comprises a lens assembly, a light source pressure ring, an LED light source, a lamp body heat sink and a nylon outer clamping ring; the lens assembly comprises a front ring, a convex lens, a light mixing film and a nylon inner clamping ring; the nylon outer clamping ring is sleeved on the outside of the first end of the front ring and fixed, and the nylon inner clamping ring is screwed into the second end of the front ring; the light mixing film is attached to one side of the plane of the convex lens; the convex lens is clamped between the front ring and the nylon inner clamping ring; the nylon outer clamping ring is screwed into the lamp body heat sink, and the lens assembly is sleeved inside the lamp body heat sink; the LED light source is fixed at the center of the light source pressure ring, and the light source pressure ring is fixed in the lamp body heat sink.
[0006] Its further technical feature is that the nylon outer snap ring and the nylon inner snap ring are both made of nylon material.
[0007] Its further technical features are that a threaded ring is provided on the outer side of the first end of the nylon inner retaining ring; the outer diameter of the first end of the nylon inner retaining ring is smaller than the outer diameter of the front ring; the threaded ring of the nylon inner retaining ring is screwed into the front ring, and the nylon inner retaining ring is connected to the front ring.
[0008] Its further technical features are: the inner diameter of the nylon outer clamping ring is larger than the outer diameter of the front ring; the inner wall of the nylon outer clamping ring is provided with a buckle, and the first end of the front ring is clamped in the buckle of the nylon outer clamping ring; the outer side of the first end of the nylon outer clamping ring is provided with a threaded ring; the threaded ring of the nylon outer clamping ring is screwed into the heat sink of the lamp body, and the nylon outer clamping ring is connected to the heat sink of the lamp body.
[0009] Its further technical feature is that the second end of the nylon inner snap ring has a snap structure; the snap structure of the nylon inner snap ring is inserted into the lamp body radiator, and the nylon inner snap ring is connected to the lamp body radiator.
[0010] Its further technical feature is that the center of the LED light source, the center of the convex lens and the center of the light mixing film are all on the same axis.
[0011] Its further technical feature is that the light-mixing film is a film-like structure with a matte surface.
[0012] The beneficial effects of the present invention are as follows:
[0013] The difference between the present invention and the prior art is that a layer of frosted film structure is added behind the convex lens, which is called a light mixing film, and is fixed with the lens to form a lens assembly block. The actual technical problem solved is that clear imaging can be achieved to achieve the lighting effect required for lighting.
[0014] In addition, there is a circle of elastically deformable structural components made of nylon material at the bottom of the lens assembly block, which forms damping with the inner wall of the lamp body. In addition, there is a positioning ring at the mouth of the lamp body, and there is also a circle of elastically deformable structural components made of nylon material inside, which forms damping with the outer wall of the lens assembly, realizing two dampings of two axial sections during the focusing process, and the double damping structure enhances the reliability of the product. The present invention realizes the simplification of the focusing structure, which is significantly lower than the cost of similar products on the market. The elastic nylon component is made by injection molding process, and the product precision requirements can meet the use requirements. BRIEF DESCRIPTION OF THE DRAWINGS
