Adjustable focusing type illumination lamp based on curvature adjustment of light gathering bowl

Abstract

The invention discloses an adjustable focusing type illumination lamp based on curvature adjustment of a light gathering bowl; an upper lamp cylinder and a lower lamp cylinder of the illuminating lampare in threaded connection; a strip-shaped side hole is formed in the side wall of the upper lamp cylinder; a lead screw is arranged in the center of the bottom surface of a lamp stand; sliding chutes are formed in the inner wall of the upper lamp cylinder at intervals; the circumferential surface of the lamp stand is provided with protrusions at intervals; the lamp stand is arranged in the innercavity of the upper lamp cylinder and the protrusions are located in the sliding chutes; a focusing disc is screwed on the lead screw and is located at the position of the strip-shaped side hole; a lamp bead is arranged in the center of the top surface of the lamp stand; the bottom end of the elastic deformable light gathering bowl is connected with the top surface of the lamp stand and the lampbead is located in the center; the top surface of the elastic deformable light gathering bowl is provided with a flanging; the lampshade is connected with the top surface of the upper lamp cylinder through threads and the flanging is fixed between the lampshade and the top surface of the upper lamp cylinder; a rear cover is connected with the bottom surface of the lower lamp cylinder through threads; and a lithium battery is arranged in the inner cavity of the lower lamp cylinder and is connected with the lamp bead through a power switch. According to the illumination lamp in the invention, curvature adjustability of the light gathering bowl is realized, the light divergence and convergence range can be continuously controlled and improved, and multiple use of the illumination lamp is realized.

Description

technical field [0001] The invention relates to the field of illumination technology, in particular to an adjustable focus illuminating lamp based on adjustment of the curvature of a concentrating bowl. Background technique [0002] With the progress of mankind and the development of science and technology, lighting has changed from the most primitive fire, oil, and finally to electricity. People are not only satisfied with its single lighting function while pursuing light. Nowadays, the use of lamps is gradually being developed and utilized, and lamps of various brands and functions have been widely used in various industries. [0003] Ordinary adjustable focus lights have a single focusing bowl to reflect light to make it converge, and a fixed focusing bowl can only reflect light to a certain range, and its ability to adjust the degree of light convergence is limited. Lighting equipment with strong light focus adjustment capabilities, such as strong light flashlights, mu...

AI Technical Summary

Problems solved by technology

Therefore, for traditional adjustable focus lighting, the focusing bowl for adjusting light convergence can only be single and fixed, and the position of the light source on the convex lens distance of the optical axis can be adjusted. Divergent, and the grinding, production, precision and cost requirements of the convex lens are high; the convex lens with large curvature is thicker, which brings a burden to the light to carry, and has a single performance in other additional practical functions
