Beaulighting High-Efficiency Anti-Glare LED Classroom Light——A New-Generation Classroom Lighting Solution Technical White Paper

1. Product Overview

Amid the national push to upgrade educational lighting, the quality of classroom lighting directly affects the visual health and learning efficiency of hundreds of millions of students. With over a decade of expertise in the lighting industry, beaulighting — guided by its corporate philosophy of "Integrity First" — introduces its new-generation high-efficiency anti-glare LED classroom light. Built on four core technology pillars — high luminous efficacy, low glare, superior optics, and intelligent dimming — this product redefines the quality standard for classroom lighting.

This product features a long rectangular recessed design with a standard length of 1200mm, a white metal frame, and a micro-prismatic diffuser surface. It enables quick recessed installation via four sets of spring clips and is compatible with gypsum board, mineral wool board, and integrated ceiling systems. Rated at 48W with a color temperature of 4000K (neutral white, ideal for classroom reading and writing), an input voltage of 220-240V, CE certification, and DALI-2 intelligent dimming support.

2. Core Technology I: High Luminous Efficacy — Industry-Leading Light Output

2.1 What is High Luminous Efficacy?

Luminous efficacy is the core metric for measuring the energy-saving performance of a luminaire, expressed in lumens per watt (LM/W). It indicates how many lumens of visible light are produced per watt of electrical power consumed. The higher the luminous efficacy, the less power is consumed for the same brightness, and the more significant the energy savings.

2.2 LED Efficacy vs. Luminaire Efficacy

Many consumers and even some manufacturers confuse the concepts of "LED efficacy" and "luminaire efficacy":

● LED Efficacy (chip-level): The luminous efficiency of the LED chip itself under ideal conditions. This product uses high-efficacy LED chips with LED efficacy reaching 200-280 LM/W, placing it in the industry's first tier.

● Luminaire Efficacy (system-level): The comprehensive luminous efficiency of the finished luminaire under actual operating conditions, including all losses from power input to final light output. This product achieves luminaire efficacy of 156-196 LM/W, far exceeding the 100-130 LM/W typical of ordinary LED classroom lights.

2.3 Complete Analysis of Luminous Efficacy Losses

From LED chip to finished luminaire, luminous efficacy undergoes four main loss stages. Beaulighting has deeply optimized each stage:

Through system-level optimization, this product achieves a system efficiency of approximately 78% from LED chip to luminaire, saving over 30% energy compared to ordinary LED luminaires. For a standard classroom using 12 lights, this translates to annual energy savings of approximately 1,500 kWh, significantly reducing the school's electricity costs.

3. Core Technology II: UGR Anti-Glare Technology — A Key Indicator for Protecting Student Vision

3.1 What is UGR?

UGR (Unified Glare Rating) is a standard metric established by the International Commission on Illumination (CIE) for measuring the degree of glare in indoor lighting, typically ranging from 10 to 30. The lower the UGR value, the less glare and the higher the visual comfort.

Glare is a significant factor contributing to visual fatigue, reduced attention, and even myopia. In a classroom environment, prolonged exposure to glare while reading and writing accelerates eye fatigue, impairs learning efficiency, and may lead to vision deterioration over time. Therefore, anti-glare is one of the core requirements for classroom lighting.

3.2 UGR Classification Standards

3.3 Beaulighting's Anti-Glare Performance

The national standard "Hygienic Standard for Daylighting and Lighting in Classrooms of Primary and Secondary Schools" (GB 7793-2010) stipulates UGR ≤ 19 as the minimum requirement for classroom luminaires. Through its prismatic plate + diffuser double-refraction optical technology, the beaulighting high-efficiency anti-glare LED classroom light controls UGR within the excellent range of 16-19, and can even reach UGR ≤ 16 under certain operating conditions — far exceeding national standards and providing students with a truly comfortable, glare-free lighting environment.

4. Core Technology III: Prismatic Plate + Diffuser Double-Refraction Optical Technology

4.1 Limitations of Traditional Diffusers

Ordinary LED panel lights typically use only a single layer of diffuser (PS or PMMA material) to homogenize light. The diffuser uniformly scatters LED point-source light through internal scattering particles, but its drawbacks are significant:

● Scattering angle is uncontrollable; light diffuses uniformly in all directions

● Excessive brightness directly below the luminaire easily causes direct glare

● UGR typically only reaches 22-25, making it difficult to meet the anti-glare requirements of classroom lighting

4.2 Prismatic Plate + Diffuser Dual-Layer Optical Structure

Beaulighting innovatively adopts a dual-layer optical structure combining a prismatic plate (micro-prism plate) and a diffuser. Both layers achieve 90% transmittance and work synergistically through different optical principles:

Layer 1: Diffuser

● Material: High-transmittance PMMA/PS

● Transmittance: 90%

● Optical Principle: Uniform scattering — light undergoes multiple refractions, reflections, and scattering through the scattering particles inside the diffuser, converting direct LED point-source light into a soft surface light source

● Core Function: Eliminates LED "graininess" and hotspots, hides LED chip images, and ensures a uniform output surface without dark areas

Layer 2: Prismatic Plate (Micro-Prism Plate)

● Material: Optical-grade PMMA/PC

● Transmittance: 90%

● Structural Features: Surface covered with micron-scale prism structures (prism size 50-200μm), with precisely designed prism apex angles of 90° or 120°

● Optical Principle: Precision angle-controlled refraction — light undergoes multiple directional refractions through the micro-prism array, precisely guiding light to the required angular range

● Core Function: Controls the light distribution curve, directs light toward desk work surfaces, reduces direct brightness below the luminaire, and fundamentally lowers glare

4.3 Double Refraction = Batwing Light Distribution Curve

The synergistic effect of the two optical layers ultimately produces the ideal batwing light distribution curve for classroom lighting:

● Peak intensity angle: 30°-60° — light is primarily projected toward desks on both sides, ensuring sufficient and uniform desk illuminance

● Low brightness directly below (0°) — reduces direct glare when students look up, which is key to anti-glare performance

● Uniform lateral diffusion — wide-angle light covers a larger area, improving illuminance uniformity

The batwing distribution curve delivers three major advantages for classroom lighting:

● Desk illuminance uniformity > 0.8 — light spreads uniformly to both sides, eliminating dark corners throughout the classroom

● No glare when students look up — low-brightness design directly below eliminates direct glare at the source

● Reduced luminaire count — wide spacing ratio design allows fewer luminaires for the same area, lowering procurement and installation costs

Ordinary diffuser luminaires achieve UGR of 22-25, while beaulighting — through prismatic plate + diffuser double-refraction technology — reduces UGR to below 16. The two refractions work synergistically: no loss of light efficacy, and more thorough anti-glare performance.

5. Core Technology IV: High-Efficiency Power Supply & DALI Intelligent Dimming

5.1 Why the Power Supply Determines Luminaire Quality

The LED driver is the "heart" of a luminaire, and its quality directly determines the overall efficacy, stability, lifespan, and safety. Low-quality power supplies have low efficiency, high heat generation, and severe flicker — not only reducing overall luminaire efficacy but also significantly shortening the luminaire's lifespan. Beaulighting insists on using industry-leading brand power supplies to ensure high efficacy and long lifespan for the complete luminaire.
