Problems solved by technology

Existing anti-glare diffusers usually use pyramidal microstructures with regular quadrilaterals as the base. Usually, after one refraction or reflection, the reduction in the glare performance of large-angle light is not ideal, and its anti-glare performance does not meet the needs of large Higher anti-glare requirements for angle light

Embodiment 1

[0021] combine figure 1 with figure 2 , and this embodiment will be described in detail. An anti-glare diffuser with stepped microstructures in this embodiment includes a transparent diffuser body 1 . A stepped pyramid structure 2 is provided on one side of the diffuser plate body 1 , and the stepped pyramid structure 2 includes a set number of pyramid bases 21 and pyramids 22 arranged at the top. The bottom surfaces of the truncated pyramids 21 and the pyramids 22 are both regular quadrilaterals, and the side lengths of the bottom surfaces of the set number of truncated pyramids 21 gradually become smaller. In this embodiment, the heights of the truncated pyramids 21 are the same, which is one-twentieth of the height of the stepped pyramid structure 2 . The taper angle of the truncated pyramid 21 is the same as the taper angle of the pyramid body 22 . The taper angle of the truncated pyramid 21 is the included angle between the two side faces at the opposite positions, a...

Embodiment 2

[0031] An illuminating device according to this embodiment includes the anti-glare diffuser plate with stepped microstructures according to Embodiment 1. The lighting device can refract and reflect the large-angle light from the panel light source multiple times, and finally transform it into small-angle light and emit it outside, thereby increasing the effective light at the center of the lighting device.

Abstract

The invention discloses an anti-dazzle diffuser plate with a step-shaped micro structure. The diffuser plate comprises a transparent diffuser plate body, and a step-shaped pyramid structure arranged in an array manner is arranged on one side of the diffuser plate body, and comprises truncated pyramids with the set number, and a pyramid body arranged on the top. According to the anti-dazzle diffuser plate with the step-shaped micro structure, the step-shaped pyramid structure arranged in the array manner is arranged on one side of the diffuser plate body, the step-shaped structure is combined with the pyramid structure arranged in the array manner, large-angle light emergent by a panel light source is subject to multi-stage refraction and reflection, the light is finally converted into non-angle light to be emergent to the outer portion, center effective light of the lighting device is improved, the UGR value of the lighting device is reduced, and it is achieved that the UGR value is smaller than 16.

Description

technical field [0001] The invention relates to the technical field of an anti-glare diffusion plate and an illumination device, in particular to an anti-glare diffusion plate with a stepped microstructure and an illumination device. Background technique [0002] In order to obtain a uniform and soft display effect, the light diffusion plate has been widely used. The light diffusion plate is to add light scattering materials to the substrate by chemical or physical means, and to use the medium of different refractive index (density) encountered by the light during transmission. When refraction, reflection and scattering occur, the incident light is fully scattered to produce the effect of optical diffusion. For light-scattering materials, light transmittance and light diffusivity (or haze) are a pair of contradictory technical indicators. Higher light transmittance is usually at the expense of light diffusivity. When the diffuser is used in the lamps, the glare problem is s...
