A method for producing 3D undulating effects of water patterns by LED water pattern lamps

Abstract

The invention discloses a method for producing a three-dimensional fluctuation effect of water lines of an LED water line lamp. The method is characterized by comprising a light source assembly, a scattering lens, a water line imaging lens A and a water line imaging lens B, wherein the light source assembly comprises an LED light source and a condensing lens group; light rays emitted by the LED light source sequentially pass through the condensing lens group, the scattering lens, the water line imaging lens A and the water line imaging lens B and then are projected and imaged to form light spots; the illumination curve of the imaging light spot presents a continuous multi-section curve with obvious illumination difference instead of a Gauss curve of a conventional light spot; the formationof the illumination curve of the imaging light spot is achieved through the motion superposition of two images, wherein the images comprise a plurality of water line patterns with obvious illumination difference; and the two images are respectively an image formed by light rays passing through the water line imaging lens A and an image formed by light rays passing through the water line imaging lens B.

Description

technical field [0001] The invention belongs to the field of lighting of stage and landscape lamps, and particularly relates to the field of a method for producing a water pattern 3D undulating effect by a water pattern lamp. Background technique [0002] In the modern society, the stage lighting market is more and more widely used, and there are more and more places of application. Sometimes it is necessary to let the lamps hit the building to produce lighting effects, which can beautify the scenery and set off the atmosphere. At present, the market There are few water pattern lamps with water pattern effect. This water pattern lamp with water pattern effect will illuminate the effect of flowing water, which is very beautiful and beautiful. At present, the water pattern effect of water pattern lamps on the market has the following expressions. [0003] The first is realized by the rotation of the water pattern drum. For example, the utility model patent publication number...

Problems solved by technology

It can be seen from the above that the "1-point light source effect" is achieved by the ratio of the length and width of the LED light source to the focal length of the swinging light-transmitting sheet and the fixed light-transmitting sheet being 1:30, which is obviously too large. Seriously increased the length of the lamp; in addition, the light directly passes through the swinging light-transmitting sheet and the fixed light-transmitting sheet, and the light intensity difference between the bright and dark areas is not explained, that is, it realizes "3-each image The technical parameters, optical principles, and actual effects of "composed of regions with large differences in light intensity" are insufficiently disclosed
