1. Product Overview

in the context of promoting and improving educational publishing at the national level, lighting quality in classrooms is directly linked to the visual health and teaching efficiency of millions of students. Bulighting Lighting—having accumulated over a decade of experience in the lighting industry and embracing the cultural value of "integrity"—has launched a new generation of high-efficiency, glare-resistant LED classroom lights. This product is built upon four core technical pillars: "high luminous efficacy, low glare, superior optics, and smart dimming," thereby redefining lighting quality standards for classroom environments.

hoc productum est designum longum, flush-mount, cuius longitudo standardis est 1200 mm. Includit structuram metallicam albam et superficiem emissionis lucis ex placa crystallina microprismatica. Facilitat installationem rapidam flush-mount per quattuor cingula elastica, et aptum est ad varia caelorum ambientes, ut tabulae gypsaceae, tabulae lanae mineralis, et caelum integratum. Potentia nominalis est 48 W; temperatura coloris est 4000 K (lucis albae neutralis, optima ad legendum et scribendum in aula); voltatio intrans est 220–240 V; certificatum est CE; et sustinet systema DALI-2 pro atenuatione intelligenti.

2. Technica prima 1: Alta efficiencia luminosa — Nivel de efficiencia in praecipuo in industria

2.1 Quid est alta efficiencia luminosa?

luminous efficacy est principalis indicator pro aestimando performance energiae conservandae lucis. Unitas eius est lumen per watt (lm/W), quod ostendit quot lumen visibile generatur per unum watt energiae electricae consumptae. Quo maior est luminous efficacy, eo minor est consumptio electricitatis ad eandem claritatem, et eo magis significativa est conservatio energiae.

2.2 Differentia inter efficaciam fontis lucis et efficaciam totius lucis

multipli consumatores et etiam quidam fabricantes confundunt duas notiones: "efficacia fontis lucis" et "efficacia totalis lucis".

• efficacia fontis lucis (in gradu chippae LED): Refertur ad efficaciam lucis chippae LED in condicionibus ideali. Hoc productum utitur chippa LED altissimae efficaciae, cuius efficacia fontis lucis attingit 200–280 lm/W, quod est in prima classe industriae.
• efficientia lucis plena (ad gradum systematis lucis praeparati): ad efficientiam lucis globalis systematis lucis praeparati in conditionibus operationis realibus refert, ubi omnes amissae, ab input electrico usque ad emissionem finalem lucis, includuntur. Efficientia lucis plena huius producti ad 156–196 lm/W pervenit, quod multo superat gradum 100–130 lm/W communium lucernarum LED.

2.3 Analysis generalis amissae efficientiae lucis

from light source to full light, light efficiency passes through four main loss stages. BYD Lighting has deeply optimized each stage:

per mediam adaptationem systematis, efficacia integralis huius producti a fonte lucis ad lucem perfectam ad 78% pervenit, quae 30% plus conservat energiam quam LED lucerna communis. Super basi usus duodecim lucernarum in classe standard, circa 1500 unitates electricitatis per annum conservari possunt, quod pretium electricitatis scholae notabiliter minuit.

3. Technica prima 2: Technica UGR anti-glare — Index principalis pro protectione visionis scholarum

3.1 Quid est UGR?

UGR (Unified Glare Rating) est index standardis a Commissione Internationali de Illuminatione (CIE) definitus, qui gradum glare in illuminatione interiori metitur. Valor eius communiter inter 10 et 30 variat. Minorem valorem UGR habet, minorem glare habebis, et maiorem visualem commoditatem.

glare vision fatigue, reduced attention, and even myopia are among the primary contributing factors. In classroom environments, students read and write for extended periods in glare-prone settings, accelerating eye fatigue, impairing teaching efficiency, and potentially causing long-term vision deterioration. Therefore, glare-resistant classroom lighting is one of the key requirements.

3.2 UGR Classification Standard

3.3 Anti-glare layer of Bulighting

national standard "Health Standards for Lighting and Illumination in Classrooms of Primary and Secondary Schools" (GB 7793-2010) specifies UGR ≤ 19 as the entry requirement for classroom lights. BlueLighting high-efficiency glare-resistant LED classroom lights, through prismatic plate + diffuser dual-refraction optical technology, control UGR within the excellent range of 16–19, reaching even UGR ≤ 16 under certain operating conditions. This far exceeds national standard requirements and truly provides students with a comfortable, glare-free lighting environment.

4. Technica originalis 3: Technica optica duplex refractio cum lamina prismatico et diffusore

4.1 Limitationes diffusoris tradicionalis

panellum LED commune saepe utitur tantum una stratum diffusoris (materia PS vel PMMA) ad aequandam lucem. Diffusor spargit uniformiter lucem e fonte punctiformi LED per particulas dispersionis internae, sed defectus eius etiam manifesti sunt:

• angulus dispersionis non regitur; lux aequaliter diffunditur in omnibus directionibus
• luciditas directe infra nimia est, quae causat glare directum
• UGR saepe tantum ad 22–25 pervenit, quare difficile est adimplere exigentias contra glare pro illuminatione in classe

4.2 Structura optica duplex: tabula prismatica + diffusor

building has adopted a dual-layer optical structure of newly developed prismatic plate (microprismatic plate) + diffuser. Both layers have 90% transmittance and cooperatively operate via different optical principles:

first layer: Diffuser

• material: High-transmittance PMMA/PS
• transmittance: 90%
• optical Principle: Uniform Scattering — Light passes through internal scattering particles of the light diffuser, undergoing multiple refractions, reflections, and scatterings, transforming the direct light from the LED point source into a soft surface source
• primary Function: Eliminate the "particle effect" and hotspots of the LED chip, conceal the chip's image, and achieve uniform light-emitting surface without any dark areas

secunda stratum: Prismatic plate (Prismatic / Microprismatic plate)

• materia: Optical grade PMMA/PC
• transmittance: 90%
• proprietates structurales: Superficies cum structuris prismatibus microscopica (magnitudo prismatis 50–200 μm), angulus apicis prismatis exacte designatus ut 90° vel 120°
• principium opticum: exacta directio anguli per refractio — lux transibit per microprismaticam seriem, multas directiones refractiōnis experiēns, et lucem exacte in angulārem limitem necessārium diriget
• praecipua functiō: curvam distributionis lucis regere, lucem ad superficiem operativam tabulae dirigere, fulgorem directum sub lūce minuere, et glare ab origine minuere

4.3 Dual Refraction = Batwing Light Distribution Curve

the synergistic action of two optical plates ultimately creates the most ideal batwing light distribution curve (Batwing Distribution) for classroom lighting:

• peak Light Intensity Angle: 30°–60° — Light spreads primarily toward desk directions on both sides, ensuring sufficient and uniform illumination on desks
• low glare at 0° downward — reduces direct glare when students look upward; this is the key to glare resistance
• symmetrical distribution on both sides — wide-angle light covers a broad area, improving light uniformity

batwing light distribution curve provides three main benefits for classroom lighting:

• desk light uniformity 0.8 — light spreads evenly on both sides, leaving no dark corners across the entire classroom
• students looking upward experience no glare — direct-down low-glare design, eliminating direct glare from the source
• fewer lights — large spacing ratio design, reducing the number of lights per equal area, lowering purchase and installation costs

uGR of common diffuser light is 22–25, whereas Builighting’s prismatic plate + diffuser dual refraction technology reduces UGR below 16. The synergistic action of two refractions does not compromise light efficiency and makes glare resistance more complete.

5. Core Technology 4: High-efficiency power supply and DALI smart dimming

5.1 Why does the power supply determine overall light quality?

The LED driver power supply is the "heart" of the light, and its quality directly determines the overall light's luminous efficiency, stability, lifespan, and safety. Low-quality power supplies exhibit lower efficiency, higher heat generation, and severe flicker—reducing not only the overall light's efficiency but also significantly shortening its lifespan. Top-tier brands in the lighting industry are committed to using premium power supplies to ensure high efficiency and extended lifespan of the complete light.
