Abstract

The invention discloses a lighting device and particularly relates to a stereoscopic lighting device reducing UGR value. The lighting device comprises a panel light source, a reflector, a light guideplate, a diffusion plate and an anti-dazzle plate. The anti-dazzle plate is composed of a microstructure layer, a transparent base plate layer and a micro-lens layer. On one hand, cones arranged in anarray in the microstructure layer enable large-angle light rays given out by the panel light source to generate multi-grade refraction or reflection, and the large-angle light rays are converted intosmall-angle light rays and conduct emergency to the outside finally, and therefore the UGR value of the whole lighting device is lowered. On the other hand, the micro-lens layer can cooperate with the transparent base plate layer and the microstructure layer to enable the light rays given out by the panel light source to show stereoscopic graphic-text information. In this way, due to the anti-dazzle layer, the UGR value of the lighting device can be reduced, the anti-dazzle effect is achieved, and the stereoscopic graphic-text information can be shown; and in this way, the visual effect and the lighting quality are improved, and the decorative fashion sense and science and technology sense are shown.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a three-dimensional lighting device for reducing UGR value. Background technique [0002] UGR (Unified Glare Rating, unified glare value), is a parameter used to measure the subjective response of the light emitted by the lighting device in the indoor visual environment to the uncomfortable feeling of the human eye. The UGR test stipulates that the lighting device is perpendicular to the direction of the ceiling. It is 0 degrees, the direction parallel to the direction of the lighting device and the ceiling is 90 degrees, and the light in the direction of the direction in the range of 65 degrees to 90 degrees will produce glare. At present, some countries in Europe have issued standards for indoor lighting. For example, Germany mandates that lighting devices whose UGR value is less than 19 can be used for indoor lighting. [0003] In the prior art, the diffusion plate in the li...
