Lighting lamp for LED (Light Emitting Diode) three-dimensional pixel induction screen

Abstract

The invention relates to a lighting lamp for an LED (Light Emitting Diode) three-dimensional pixel induction screen, which comprises a metal bottom shell, an upper shell with lenses and multiple light source modules, wherein the multiple light source modules are installed at the inner bottom of the metal bottom shell and connected with a DMX512 signal wire; the upper shell and the metal bottom shell are fastened together; each light source module comprises a substrate, a control driving circuit, multiple LED modules and a bidirectional light reflection cup which is arranged at one end of the substrate; light emitted by the LED modules on the end surfaces of the substrates is guided to the two sides of the modules through the bidirectional light reflection cups, and the light emits from the corresponding lenses of the upper shell to be used as a pixel point light source; light emitted from the LED modules on the front surfaces of the substrates transmits through the corresponding lenses of the upper shell to be used as a background light source; the light source modules are connected according to DMX512 standards; multiple LED pixel points which are independently controlled can emit light from the right surfaces and two sides of the LED pixel points polydirectionally; and the intensity and time of each pixel point are controllable. The lighting lamp provided by the invention isapplicable to the folded composite polyhedron structure of a large-area glass curtain wall and can be used for forming background light and dynamic or static or dynamic and static combined three-dimensional lattice patterns.

Description

technical field [0001] The invention belongs to the technical field of decorative lighting for buildings with glass curtain walls, in particular to a lighting fixture for an LED three-dimensional pixel induction screen, which can be used in a three-dimensional lighting system for a glass curtain wall of a building to form background light and three-dimensional points array pattern. Background technique [0002] In the landscape lighting project, the indoor and outdoor building wall facades are illuminated by lights, and LED floodlights are usually used to achieve monochromatic light or colorful light color lighting. At present, there are two types of LED floodlights on the market: point light source structure and strip structure. They all adopt the design of emitting light from a single side, and the angle of the emitted light is small, the energy of light is large, and the distance of projected light is long. . The light-emitting surface of the floodlight is single. Altho...

AI Technical Summary

Problems solved by technology

That is to say, several light sources can be directly observed on the facade of the building, or light pollution can be observed, so the wall washing lighting method using the above-mentioned LED floodlights is not suitable for use in buildings with three-dimensional transparent glass curtain walls
