I. Product Description

In the context of the national vigorous promotion of renovation and improvement of educational lighting, the light quality in classrooms is directly linked to the visual health and learning efficiency of hundreds of millions of students. Beaulighting, leveraging over a decade of experience in the lighting industry and guided by its corporate culture rooted in “integrity,” introduces the new generation of high-efficiency, anti-glare LED classroom luminaires. This product rests on four core technological pillars—“high luminous efficacy, low glare, superior optics, and intelligent dimming”—to redefine the light-quality standard for classroom lighting.

Hoc productum designum elongatum incorporatum habet, cuius longitudo standardis 1200 mm est. Includit structuram metallicam albam et superficiem emissionis lucis laminam microprismatum crystallinorum. Installatio celeris et incorporata per quattuor series uncinatorum elasticorum fit, et cum variis caelis compatibile est, ut tabulae gypseae, tabulae lanae mineralis, et caeli incorporati. Potentia nominalis 48 W est, temperatura coloris 4000 K (lux albus neuter, optime aptus ad legendum et scribendum in aula scholastica), tensio intrantis 220–240 V, certificatum CE habet, et cum systemate intelligentis dimmer DALI-2 compatibile est.

II. Technologia Fundamental 1: Alta Efficiens Lucis — Gradus Efficiens Dux in Industria

2.1 Quid est Alta Efficiens Lucis ?

Luminous efficacy est le parametrum fundamentalis ad mensurandam efficaciam energiae conservandae in lumine. Unitas eius est lumen per watt (lm/W), quod quantitatem lucis visibilis indicat, quae ex singulo watt electricae energiae generatur. Quo maior est luminous efficacy, eo minor est consumptus electricus pro eodem lumine, et eo maiora sunt conservationes energiae.

2.2 Differentia inter Luminis Fontis Efficaciam et Totius Luminis Efficaciam

Multi consumptores et etiam quidam fabricantes confundunt conceptus 'luminis fontis efficaciae' et 'totius luminis efficaciae':

• Efficientia fontis lucis (in chip LED): significat efficientiam lucis ipsius chip LED sub condicionibus ideales. Hoc productum utitur chip LED ad altam efficientiam, quarum efficientia fontis lucis attingit 200–280 lm/W, in primo gradu industriae posita.
• Efficientia luminaris integri (in systemate luminaris finito): significat efficientiam lucis integram luminaris finiti sub condicionibus operationis realibus, omnes amissas a ingressu electricitatis usque ad emissionem lucis finalis includens. Efficientia luminaris integri huius producti attingit 156–196 lm/W, multo superans gradum 100–130 lm/W luminarium LED communium pro aulis scholasticis.

2.3 Analysis Plena Amissarum Efficientiae Lucis

From light source to complete luminaire, luminous efficacy undergoes four main loss stages. Beaulighting has performed in-depth optimization at each stage:

Grâce à l'optimisation au niveau du système, l'efficacité intégrale de ce produit, de la source lumineuse au luminaire complet, atteint environ 78 %, ce qui représente une économie d'énergie de plus de 30 % par rapport aux luminaires LED courants. En prenant comme référence une salle de classe standard avec 12 luminaires, on peut économiser environ 1500 kWh par an, réduisant significativement les coûts électriques de l'établissement éducatif.

III. Technologie Fondamentale 2 : Technologie Anti-Éblouissement UGR — Indicateur Clé pour Protéger la Vue des Étudiants

3.1 Qu'est-ce que l'UGR ?

L'UGR (Unified Glare Rating, indice unifié d'éblouissement) est l'indicateur standard établi par la Commission Internationale de l'Éclairage (CIE) pour mesurer le degré d'éblouissement en éclairage intérieur. Sa plage de valeurs est généralement de 10 à 30. Plus la valeur UGR est basse, plus l'éblouissement est faible et plus le confort visuel est élevé.

Glare is one of the key factors causing visual fatigue, reduced attention, and even myopia. In classroom environments, prolonged student reading and writing under glare conditions accelerates eye fatigue, impairs learning efficiency, and over time may even lead to vision deterioration. Therefore, glare control is a fundamental requirement for classroom lighting.

3.2 UGR Classification Standard

3.3 Gradus Anti-Flagrantiae Beaulighting

Norma nationalis « Norma Hygienica Illuminationis et Lucis Naturalis in Aulis Scholarum Primariarum et Secundariarum » (GB 7793-2010) statuit UGR ≤ 19 ut condicio admissibilitatis pro luminariis in aulis scholarum. Luminarium LED pro aulis scholarum Beaulighting, altam efficaciam et anti-flagrantiam habens, per technicam opticam duplicis refracturae cum lamina prismatica + diffusore, UGR in optimo intervallo 16–19 regit, et in quibusdam condicionibus operativis etiam UGR ≤ 16 attingit. Hoc normam nationalem latissime superat, studentibus verum ambience illuminationis commodum et sine luce flagrante praebens.

IV. Technica Fundamentalis 3: Technica Optica Duplicis Refracturae cum Lamina Prismatica + Diffusore

4.1 Limites du Diffuseur Traditionnel

Les luminaires à panneau LED courants n'utilisent généralement qu'une seule couche de diffuseur (en matériau PS ou PMMA) pour homogénéiser la lumière. Le diffuseur disperse uniformément la lumière des sources ponctuelles LED au moyen de particules de diffusion internes, mais ses inconvénients sont évidents :

• L'angle de dispersion n'est pas contrôlable ; la lumière se diffuse uniformément dans toutes les directions
• La luminosité directement en dessous est excessive, favorisant l'éblouissement direct
• L'UGR n'atteint généralement que 22-25, difficile de satisfaire aux exigences anti-éblouissement de l'éclairage des salles de classe

4.2 Structure Optique à Double Couche : Plaque Prismatique + Diffuseur

Beaulighting innovatively adopts a double-layer optical structure comprising a prismatic plate (microprism plate) plus a diffuser. Both layers exhibit 90 % transmittance and operate synergistically according to distinct optical principles:

First Layer: the Diffuser

• Material: high-transmittance PMMA/PS
• Transmittance: 90 %
• Optical principle: uniform dispersion — as light passes through internal scattering particles within the diffuser, it undergoes multiple refractions, reflections, and dispersions, converting direct light from LED point sources into a soft, surface-emitting light source
• Primary function: eliminate the "grainy effect" and LED chip hotspots, conceal the LED chip image, and achieve a uniformly luminous emitting surface free of dark zones

Second Layer: the Prismatic Plate (Prismatic / Microprism Plate)

• Material: optical-grade PMMA/PC
• Transmittance: 90 %
• Characteristics structurales: superficies cooperata de structuras de prismas in le nivello micrometrico (dimension del prisma: 50–200 μm), con le angulo del vertice del prisma disignate precise a 90° o 120°
• Principio optic: refractio con controllo angular precise — le luce, transmittente per le rete de microprismas, subi multe refractiones directionales, guidante le luce precise verso le angulo angular desiderate
• Function principal: controllo del curva de distribution luminose, dirigente le luce verso le superficies de laboro del bancos, reducendo le luminositate directe sub le luminaire e diminuente le abbagliamento ab su fonte

4.3 Refractio Duplex = Curva de Distribution Luminose in Forma de Ala de Vespertilio

Le action synergic de ambe le stratos optic produce finalmente le curva de distribution luminose in forma de ala de vespertilio (Batwing Distribution), le plus ideal pro le illumination de salas de classe:

• Angulus intensitatis lucis apicis: 30°–60° — lux principaliter ad scrinia lateralia dirigatur, sufficientem et aequabilem illuminationem in scriniis garantens
• Infima lux directe infra (0°) — directum glareminem minuit, cum discipuli oculos suos tollunt; hoc est clavis ad antiglareminem
• Aequabilis diffusio ex utraque parte — lux lati anguli latiorem regionem amplectitur, aequabilitatem illuminationis meliorans

Curva distributionis lucis in forma alae vespertilionis tres praecipuos beneficios pro illuminatione scholarum offert:

• Aequabilitas illuminationis in scriniis 0,8 — lux aequaliter ad latera diffunditur, nullis tenebris in angulis per totam scholam
• Nullum glaremen in elevatis oculis — designatio infimae luminositatis directe infra, glaremen directum ab ipsa fonte tollens
• Minus luminaria — design cum magna spatium proportione, quod numerum luminarium pro eadem superficie minuit, ergo pretia emptionis et installationis deminuit

Dum luminaria cum diffusore communis UGR 22–25 habent, Beaulighting, per technologiam duplicis refractionis cum lamina prismatica + diffusore, UGR infra 16 reducit. Actio synergica duarum refractionum efficacitatem luminis non impedit et completiorem anti-glare effectum praebet

V. Technologia Fundamental 4: Alimentatio Altae Efficientiae et Intelligentis Variatoris DALI

5.1 Cur Alimentatio Qualitatem Totius Luminarii Determinat?

The LED driver power supply is the 'heart' of the luminaire, and its quality directly determines the luminous efficacy, stability, service life, and safety of the entire luminaire. Low-quality power supplies exhibit low efficiency, excessive heat generation, and severe flicker—reducing not only the luminaire’s efficacy but also drastically shortening its service life. Beaulighting firmly commits to using top-tier industry-brand power supplies, ensuring high efficacy and extended service life for the complete luminaire.
