Illumination lamp having dynamic display function

Abstract

The invention discloses an illumination lamp having a dynamic display function. The illumination lamp comprises a light source and a light source scattering layer, wherein the light source is arranged in the light source scattering layer; an optical switch film layer is arranged at the outer side of the light source; and a plurality of lattice driving circuits for controlling the film layer light transmittance are arranged on the optical switch film layer. The outer side of the light source is covered with the lattice-type optical switch film layer (e.g. a PDLC film), and voltage input of an optical switch is controlled through the driving circuits, so that light transmission and no light transmission of the corresponding lattice positions on the film layer can be realized, and pattern display is realized. Display contents can be information such as patterns, temperatures and time. The illumination function of the illumination lamp is realized, and certain patterns can be displayed on the illumination lamp visually.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to a lighting fixture with a dynamic display function. Background technique [0002] The traditional marquee uses air flow to display dynamic patterns. Specifically: the candle heats the air, the hot air rises, creates airflow, and the airflow drives the wheel shaft to rotate, so the paper-cutting rotates with the wheel shaft, and the lamp formed according to this principle is a revolving lantern. The candles in the revolving lantern need to be cut into small pieces, and when put in the revolving lantern, they must be placed upright, not obliquely. Although simple, it realizes the functions of lighting and pattern display. [0003] The integration of lighting functions is the development trend of lamps such as table lamps, chandeliers, and decorative lights in the future. In addition to basic lighting functions, existing lamps are also increasingly integrating functions such as ...

Problems solved by technology

However, the current integration is mostly just the superposition of simple functions, such as the mechanical connection of clocks and lighting lamps through molds, and no real functional integration has been achieved.
