Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular to a high-light-density, low-glare intelligent control system. Background Art

[0002] Traditional lighting fixtures primarily utilize LED light sources, light distribution lenses, or reflectors. Most of these fixtures use Lambertian light distribution (LED light sources), with little or no light distribution, or the light distribution is not suitable for on-site lighting needs. This leads to light pollution and light waste. Furthermore, improper use can cause glare to workers, hindering production and daily life.

[0003] For lighting, uniform illumination in all directions, good lighting effects, and large angle requirements are required; while glare is related to the background brightness, the brightness of the luminous part of each lamp in the direction of the observer's eyes, the solid angle formed by the luminous part of each lighting fixture to the observer, and the deviation of the line of sight direction of each lighting fixture.

[0004] Prior art Chinese patent application publication number CN113669664A discloses a healthy, intelligent classroom lighting system. This system uses classroom lamps to illuminate the entire classroom, while also using writing board lamps to illuminate the writing board. A classroom lighting mode switch allows for switching between different lighting modes. The classroom lamps incorporate anti-glare panels, which refract incident light from various angles through a series of refractions, then emit it within a narrow range. This softens the light and reduces glare, meeting school lighting requirements and effectively protecting students' eyes. The writing board lamps combine lens light distribution with light reflection from a curved reflector to achieve an excellent light distribution curve, resulting in superior illumination, uniform illumination across the illuminated surface, and zero glare. Furthermore, by pressing a writing board lamp adjustment button, the lighting range, angle, and effect of the writing board lamps can be adjusted to meet the needs of writing board lighting in various scenarios. However, light distribution based solely on lens light distribution and curved reflector light distribution is not precise or intelligent enough, and the low-glare effect is insufficient for current use cases. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention proposes a high-light-density, low-glare intelligent control system. Through the design of a hierarchical light control architecture, an intelligent light distribution module and an AI control module, low-glare intelligent control of high-light-density LED lamps can be achieved, thereby achieving better anti-glare effects.

A circle of edge is formed inside the end edge after the transparent lampshade and the mounting chassis are combined; the intelligent light distribution module senses the environmental status through the environmental perception module, and then formulates the control strategy through the control strategy implementation module, and then automatically adjusts between the three factors of light effect, anti-glare and cost through the adaptive light distribution algorithm module; the AI ​​control module adjusts the curvature radius through AI, the real-time beamforming algorithm of the MEMS micromirror array, and the performance parameters of the diffusion film and acrylic light guide ring are combined to generate the light distribution plan through AI, and the Diffusion model is used to generate the asymmetric free-form surface optical device in the range of 3000-8500cd / m 2 The 4H / 8H UGR is achieved under optical density <19, the light efficiency loss is controlled within 12%, and the color gamut stability Δuv <0.003.

[0020] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary persons in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment: A high light density and low glare intelligent control system.

[0022] Reference Figures 1 to 2 As shown, a high light density and low glare intelligent control system includes:

[0023] A hierarchical light control architecture includes a mounting chassis 1, an acrylic light guide ring 2, a diffusion film 3, an anti-glare film 4, a transparent lampshade 5, and an LED light-emitting module. The LED light-emitting module is mounted on the inner side of the mounting chassis 1. A light-emitting module alignment mounting hole 11 is provided at the top center of the mounting chassis 1. Fixing screw holes 12 are provided on both sides of the light-emitting module alignment mounting hole 11. Side positioning mounting holes 13 are provided on the end edges of the mounting chassis 1. During actual installation, the mounting chassis 1 is aligned with the LED light-emitting module through the light-emitting module alignment mounting hole 11. The fixing screw holes 12 and the side positioning mounting holes 13 are used for fixing the mounting chassis 1 to the ceiling. The anti-glare film 4 is fitted into the transparent lampshade 5. The anti-glare film 4 is a microstructured anti-glare film with a V-cut angle of 25°±1° and a period of 50μm. The function of the microstructured anti-glare film is to achieve 4H / 8H viewing angle UGR suppression, thereby achieving a good anti-dizziness effect. A diffuser film 3 is fitted over the anti-glare film 4. This nanoprismatic diffuser has a haze of 92% ± 2% and a transmittance of 88%. The nanoprismatic diffuser eliminates the graininess of the LED light, ensuring a uniform outward diffusion of the light generated by the module. An acrylic light guide ring 2 is mounted on the diffuser film 3, and the diffuser film 3 and anti-glare film 4 are compressed within a transparent lampshade 5. The acrylic light guide ring 2 has a refractive index of 1.49 and ensures 360-degree uniform light distribution while reducing the intensity of light emitted from the side edges. The transparent lampshade 5 is secured to the bottom of the mounting chassis 1, and the acrylic light guide ring forms a rim around the edge of the combined transparent lampshade and mounting chassis. The top 51 of the end edge of the transparent lampshade 5 is provided with multiple positioning and snap-fitting holes 52. The bottom edge of the mounting base 1 is provided with multiple clips that match the positioning and snap-fitting holes 52. The mounting base 1 and the transparent lampshade 5 are connected by the clips and the positioning and snap-fitting holes. The transparent lampshade 5 is made of PC and has a thickness of 2mm, a light transmittance of >95%, and a hardness of 3H. This makes the transparent lampshade 5 both hard and protective, and provides good light transmission.

[0024] The intelligent light distribution module includes: an environmental perception module that uses a UWB sensor to locate the sitting height of the person, scans the material of the reflective surface, and distinguishes whether the reflective surface is matte or glossy; a control strategy implementation module that increases the light density in the central area by 20%, enhances the light density in the 500-600nm band (eye protection mode), and calculates the cumulative irradiance in real time (in compliance with CIE157:2004 standards). When the light density of the sensitive exhibit surface multiplied by time exceeds the threshold, dimming protection is automatically triggered; an adaptive light distribution algorithm module that uses a CNN / Transformer network to analyze environmental images (such as spatial structure and pedestrian flow), generates the optimal light distribution curve in real time, dynamically adjusts the beam angle (adjustable from 15° to 120°) and illumination uniformity (>0.8), and combines genetic algorithms with reinforcement learning to automatically adjust between the three factors of light efficiency (>130lm / W), anti-glare (UGR <16), and cost.

[0025] The AI ​​control module uses AI to adjust the curvature radius and the real-time beamforming algorithm of the MEMS micromirror array. Combined with the performance parameters of the diffusion film (haze 92% ± 2%, transmittance 88%) and the acrylic light guide ring (refractive index 1.49, annular sawtooth structure, tooth pitch 0.5mm), AI generates a light distribution solution (including optical structure + drive parameters), reducing the UGR from 22 to below 16. The Diffusion model is used to generate asymmetric free-form surface optical devices with a brightness of 3000-8500cd / m 2 The 4H / 8H UGR is achieved under optical density <19, the light efficiency loss is controlled within 12%, and the color gamut stability Δuv <0.003.

By designing a hierarchical light control architecture, an intelligent light distribution module, and an AI control module, it can achieve low-glare intelligent control of high-light-density LED lamps, thereby achieving a better anti-glare effect. Through the design of the hierarchical light control architecture, the present invention can effectively reduce the difference in light density between the front and side surfaces of the transparent lampshade 5 by installing an acrylic light guide ring 2 and an anti-glare film 4 within the transparent lampshade 5, thereby achieving a better anti-glare effect. During actual operation, the LED light module generates light and diffuses it outward through the front and surrounding areas of the transparent lampshade 5. The diffusion film 3 can evenly diffuse the light generated by the LED light module outward. The anti-glare film 4 can reduce the dizziness effect caused by direct light from the front of the transparent lampshade 5. At the same time, the acrylic light guide ring 4 can reduce the intensity of light emitted from the side edges of the transparent lampshade 5 and the mounting chassis 1, thereby effectively reducing the difference in light density between the front and side surfaces of the transparent lampshade 5, thereby achieving a better anti-glare effect. In order to more accurately control the anti-glare effect and adapt to the anti-glare needs of different environments and different groups of people, the present invention also sets up an intelligent light distribution module and an AI control module. Among them, the intelligent light distribution module can sense the environmental state, automatically generate a control strategy, and automatically adjust between the three elements of light effect, anti-glare and cost.
