アンチ - 快適な商業空間のためのグレア ロー UGR LED リニア ライト

Imagine walking into an office or a shopping mall and feeling instantly comfortable—thanks to Anti-Glare Low UGR LED Linear Lights—not squinting at harsh lights, not being distracted by glaring reflections.

In today’s commercial spaces, lighting is no longer just about brightness. With low UGR LED lighting (UGR ≤ 19), glare is minimized, and eyes are happier—whether you’re working on a report, browsing products, or attending a lecture. It’s about creating an environment where people can focus, shop, or study without visual fatigue.

These lights are carefully designed with smart optical components—like diffusers, lenses, and honeycomb louvers—to make sure light spreads evenly without harsh peaks. The result? A comfortable commercial lighting environment that enhances productivity, improves customer experience, and elevates the overall aesthetic of the space.

What Is UGR and Why It Matters in Lighting Design?

UGRとは何ですか？

Unified Glare Rating (UGR) is a standardized metric developed by the CIE (International Commission on Illumination) to quantify visual discomfort caused by glare in indoor lighting environments. UGR provides a numerical value that indicates how likely a light source is to cause discomfort when viewed from a typical seated position.

UGR values range from 5 (very low glare) to 40 (extremely high glare). For commercial spaces such as offices, schools, and retail environments, maintaining a UGR below 19 is generally recommended to ensure a comfortable visual experience.

How UGR Is Calculated?

UGR is not a fixed property of a luminaire but depends on the lighting installation as a whole. Factors that influence UGR include:

Luminance of light sources

• Background luminance
• Observer position & viewing angle
• Room geometry
• Surface reflectance
• Luminaire arrangement (spacing, height, orientation)

In practice, software such as Dialux, Relux, or AGi32 is commonly used to simulate these parameters and calculate UGR values. According to the TRILUX “UGR Table Method,” standardized room sizes, surface reflectance values, and observer positions are applied to make results comparable across different products.

Standardized arrangement of the observer and the horizontal luminaire plane, positioned at H = h – p – 1.2 (in meters) above the observer’s eye level for seated positions, where p represents the suspension length of the luminaire row.

For narrow luminaire arrangements (s = 0.25 H), the UGR value remains almost independent of the observer’s viewing position.

With wider luminaire spacing, observer B1 experiences a lower UGR while observer B2 sees a higher UGR. However, both values generally stay below the UGR level observed in narrow luminaire arrangements.

注： According to EN 12464-1, UGR tables can also be based on luminaire distances greater than s = 0.25 H. For example, in Great Britain, s = 1.0 H is commonly used, which results in lower UGR values and higher luminaire efficiency. However, this requires designers to carefully check observer positions to avoid higher glare at certain viewing angles.

Why UGR Matters?

Enhancing Visual Comfort

Low UGR lighting reduces direct glare and hotspots, minimizing eye strain during prolonged activities such as working on a computer, reading, or attending classes.

Supporting Productivity

Well-controlled glare improves concentration and performance. Studies show that employees or students in low-glare environments maintain focus longer and experience less fatigue.

Creating a Professional and Inviting Atmosphere

In retail or hospitality settings, low-glare lighting ensures that products, displays, and architectural features are clearly visible without discomfort, improving customer experience.

Achieving UGR Targets

Manufacturers often label products as “UGR<19,” but this does not guarantee the light alone achieves the rating. Instead, it indicates that the luminaire’s optical design (e.g., diffusers, louvers, lenses) supports achieving the target when properly installed in a suitable environment.

Features of Anti-Glare Low UGR LED Linear Light

Low UGR LED linear lights are engineered to reduce visual discomfort and create comfortable commercial spaces. Their performance is determined not only by the LED chips but also by optical components, housing design, and precise light distribution.

Applications of Low UGR LED Linear Light

Low UGR LED linear lights are widely used in modern commercial and institutional spaces where visual comfort is a priority. By minimizing glare, they help create productive, welcoming, and aesthetically pleasing environments.

オフィス照明

In open-plan offices, meeting rooms, and co-working spaces, glare-free lighting reduces eye strain and supports long hours of computer work. Maintaining UGR<19 is often a design requirement in corporate environments to comply with international lighting standards (e.g., EN12464).

Retail & Shopping Malls

Retail spaces benefit from low UGR lighting as it provides clear product visibility without causing discomfort to shoppers. Linear lights with anti-glare diffusers or louvers enhance merchandise display while keeping the shopping experience comfortable and inviting.

Educational Institutions

Classrooms, libraries, and lecture halls require lighting that supports concentration and reduces visual fatigue. Low UGR LED linear lights help students and teachers stay focused, creating an optimal environment for learning and reading.

Hospitality & Public Spaces

In hotels, lobbies, restaurants, and public waiting areas, lighting must balance comfort and aesthetics. Low UGR linear fixtures prevent discomfort for guests while enhancing architectural details, signage, and interior ambiance.

Comparison: Low UGR Linear Light vs. Conventional Lighting

When evaluating lighting for commercial spaces, it is important to compare low UGR LED linear lights with conventional fixtures such as standard fluorescent lamps, basic LED panels, or non-optimized linear lights. The differences highlight why glare control is essential in modern lighting design.

視覚的な快適さ

• Low UGR Linear Light: Designed with diffusers, louvers, or reflectors to reduce glare, creating a soft and balanced illumination that minimizes eye strain.
• Conventional Lighting: Often produces direct glare or visible bright spots, especially from bare tubes or low-quality panels, leading to discomfort during long exposure.

Compliance with Standards

• Low UGR Linear Light: Meets requirements of EN12464, WELL Building Standard, and LEED lighting guidelines, especially the UGR<19 criterion in offices and classrooms.
• Conventional Lighting: May fail to comply with modern glare requirements, making it unsuitable for projects where certification and visual comfort are important.

Productivity and User Experience

• Low UGR Linear Light: Enhances focus, reduces fatigue, and creates a pleasant atmosphere, directly supporting higher productivity and customer satisfaction.
• Conventional Lighting: Can cause eye discomfort, headaches, and reduced concentration, negatively affecting work efficiency and user experience.

Aesthetics and Architectural Integration

• Low UGR Linear Light: Offers sleek designs, uniform light output, and minimal glare, enhancing the architectural aesthetics of modern offices, retail, and hospitality spaces.
• Conventional Lighting: Outdated designs or uncontrolled light distribution may disrupt interior aesthetics and create uneven illumination.

How to Select the Right Low UGR LED Linear Light & Buyer’s Checklist

When choosing anti-glare linear lighting for offices, schools, retail, or hospitality projects, it’s not enough to look at product datasheets. Buyers should verify whether the fixtures truly meet performance and compliance requirements. The following guidelines turn technical features into practical procurement checks.

Verify UGR Test Reports

• Request official UGR test data from the supplier, not just marketing claims.
• Confirm the values are tested under EN 12464-1 conditions (e.g., UGR ≤19 for offices/classrooms).

Request Samples for On-Site Evaluation

• Check glare control, light uniformity, and comfort in a real project environment.
• Place luminaires at intended mounting heights to simulate final effect.

Confirm Certification & Compliance

• Look for CE, RoHS, UL, and EN 12464-1 compliance.
• Certification ensures safety, quality, and suitability for international tenders.

Evaluate Project Flexibility

• Does the manufacturer offer custom lengths, tunable CCT, or smart control (DALI/DMX)?
• Flexibility ensures lighting can adapt to evolving project requirements.

Check Warranty & After-Sales Support

• A minimum of 3–5 years warranty is recommended.
• Reliable after-sales service reduces risks in long-term projects.
