LEDESTAR 2835 LED Series High-CRI, Eye-Protecting, And Health-Focused Educational Lighting
Leave a message
Product Overview:
Targeting visual health needs across three key scenarios-educational lighting, home reading/writing lighting, and wellness/healthcare lighting-this series integrates LEDESTAR's proprietary Bio-Light spectral technology into the 2835 package platform. Building upon the foundations of high color rendering and low blue light, it incorporates photobiological effect design to deliver a next-generation light source solution for the healthy lighting industry.
Positioned as a dedicated light source for healthy educational lighting, this series highlights four core features: high color rendering, low blue light, circadian rhythm friendliness, and physiological eye protection. It represents a specialized product line launched by LEDESTAR for the healthy lighting market segment.
In recent years, full-spectrum LEDs have rapidly penetrated the eye-protecting lighting market due to their high color rendering capabilities. However, most solutions have relied on the technical approach of using blue-light chips to excite phosphors, resulting in persistent issues such as an excessive proportion of short-wave blue light and insufficient long-wave energy.
The Bio-Light spectrum introduced by LEDESTAR features a recalibrated full-band energy distribution. Spectral comparison charts reveal that, compared to conventional solutions (such as single, dual, or triple blue-light configurations), LEDESTAR's Bio-Light exhibits a lower short-wave blue light peak and a smoother spectral curve. It also retains ample energy in the near-infrared band, resulting in an overall profile that more closely resembles natural sunlight.
Officially released comparative data shows that LEDESTAR Bio-Light achieves a Spectral Similarity Index (SSI) of 90, a typical Color Rendering Index (Ra) of 98.7, and an R9 (red rendering) value of 98.0. It scores a perfect 100 on the Television Lighting Consistency Index (TLCI), placing it in the industry's top tier for color metrics. Crucially, the blue light proportion in the 350–460nm range is only 5.84%-far lower than conventional full-spectrum products-while the infrared light proportion reaches 36.46%. This significantly higher infrared content is a key factor in achieving physiological eye protection.
Unlike standard eye-care LEDs that focus solely on low blue light, this product series establishes a multi-layered eye-care mechanism covering visual fatigue relief, circadian rhythm regulation, and physiological eye health maintenance.
Regarding the visual experience, a high S/P ratio (brightness factor) of 1.88 enhances visual clarity, providing a crisper view at the same illuminance level and reducing the strain of ocular accommodation. Coupled with a high-CSD spectral design, it effectively extends the duration of comfortable viewing and alleviates the soreness and fatigue associated with prolonged reading or writing.
In terms of circadian regulation, an M/P ratio (circadian factor) of 0.788 allows the light source to influence human melatonin secretion: daytime use helps maintain focus, making it suitable for school studies and home-office environments; nighttime use minimizes disruption to circadian rhythms, reducing the impact of pre-sleep lighting on sleep quality.
Targeting myopia prevention and eye health management for adolescents, the series supplements beneficial infrared light to improve microcirculation in ocular tissues and help maintain ocular surface moisture. It also helps control axial elongation, providing long-term lighting support for visual health.
Regarding safety and reliability, the series has passed EN62471 photobiological safety certification, achieving the RG0 (exempt) risk group classification. It has also passed LM-80 lumen maintenance certification, meeting the lifespan requirements for high-frequency, long-duration usage scenarios such as educational lighting.
Utilizing the standard 2835 package size, this series is directly compatible with the designs of most existing lighting products, allowing for rapid adoption without requiring major PCB redesigns. It is ideally suited for four key application areas:
- Eye-Care Floor Lamps: Suitable for large floor-standing lamps, providing uniform, healthy illumination across the entire study area in the home;
- Eye-Care Desk Lamps: Suitable for reading and writing desk lamps, meeting the eye-protection needs of students during daily study;
- Classroom Lighting: Suitable for educational lighting fixtures such as classroom flat-panel lights and blackboard lights, complying with campus classroom lighting standards;
- Wellness & Eye-Care Ceiling Lights: Suitable for ceiling fixtures in elderly care facilities and vision rehabilitation centers, combining general illumination with health and wellness benefits
.
Health-centric lighting has emerged as one of the fastest-growing segments in the LED industry. Driven by ongoing classroom lighting upgrades and rising consumer awareness regarding eye health, market demands for light sources are shifting from simple "low blue light" specifications to "comprehensive health" standards. By implementing bio-optical technology, this product series from Ledestar expands technical standards for healthy lighting from mere color rendering to physiological well-being, charting a new course for technological advancement in the industry.
As a professional distributor of LED components, Gainer LED now supplies Ledestar's 2835 high-CRI, eye-care, and educational lighting series. The company offers product selection consultation and volume supply services to global lighting manufacturers and engineering service providers, helping clients quickly establish a presence in the health-centric lighting market.
