LED (light emitting diode) lamp for glass curtain wall

Abstract

The invention provides an LED (light emitting diode) illuminating lamp for a glass curtain wall. The lamp provided by the invention comprises a metal bottom shell, an upper shell and a plurality of light source modules which are installed on the inner bottom of the metal bottom shell, wherein the upper shell and the metal bottom shell are buckled into a whole; the upper shell is provided with a plurality of pairs of front light-emitting holes, through holes and left and right light-emitting holes at intervals, and each front light-emitting hole is provided with a lens; each light source module comprises a shell, a built-in control-driven circuit, a forward light emitting device above the shell and a rotating seat arranged on one end of the shell, a bidirectional light emitting device is installed on the end face of the rotating seat, a rotatable inclined light-transmitting device is installed on the rotating seat, and the head of the inclined light-transmitting device is exposed from the through holes of the upper shell; light rays emitted from the bidirectional light emitting device shoot up from the corresponding left and right lenses to serve as a pixel point light source, and the light rays emitted by the forward light emitting device shoot up from the lens to serve as a forward background light source; and when the bidirectional light emitting device and the forward lightemitting device are in a nonoperating state, the light rays from the inclined light-transmitting device shoot up in an inclined upward direction along the right sides of the light source modules to serve as an inclined background light source.

Description

technical field [0001] The invention belongs to the technical field of decorative lighting for buildings with glass curtain walls, in particular to an LED lighting fixture for glass curtain walls. Background technique [0002] In the landscape lighting project, indoor and outdoor building wall facades are mostly illuminated by LED floodlights to achieve monochromatic or colorful lighting. LED floodlights mostly use wall-washing lighting to illuminate a single window on the facade of a transparent glass curtain wall. When two-dimensional windows use wall-washing lighting to achieve internal light penetration, it can achieve no glare and basically uniform illumination. . [0003] With the continuous emergence of new buildings, there have been three-dimensional transparent glass curtain walls that are folded left and right, up and down, or folded in half at any angle. If the above-mentioned LED floodlights are still used, and the traditional wall-washing lighting method is us...

Problems solved by technology

[0004] In addition, when the LED floodlights used for the three-dimensional transparent glass curtain wall stop playing and the screen goes out, there is no light on the glass curtain wall, and the floodlights and lamps can be seen The shape of the building will affect the appearance of the building. If the floodlights are turned on, it will cause a waste of electric energy, which is not conducive to the conservation of resources.
