Ams OSRAM’s OSLON™ Pure 1414 High-Performance Full-Spectrum LEDs Unlock New Dimensions in Stage And Architectural Lighting

Beyond RGB: What Other Possibilities Exist for Stage Lighting?

When a city landmark comes alive at night, or when the lighting at a major product launch perfectly aligns with a brand's identity, few people realize that the true quality of these visual spectacles is determined not just by stage design or architectural contours, but by the light cast into every corner.

Modern stage and cultural-tourism lighting face unprecedented challenges. Designers' visions for color have long transcended the limitations of traditional RGB systems, while the market demands solutions that are more compact, flexible, and durable. Today, an increasing number of premier venues, cultural-tourism projects, and architectural landmarks are leveraging full-spectrum LED technology and multi-primary-color dimming schemes, turning every beam of light into a language for visual storytelling.

Zheng Yunqiang, Marketing Manager at ams OSRAM, states:

"Modern lighting is no longer just about 'illumination'; it is about the precise expression of color. In the realms of stage and architectural lighting, the spectral integrity of a light source, the consistency of its color mixing, and the breadth of its color gamut have become just as critical as brightness and power consumption."

01 Introducing Full-Spectrum Light to Stage and Architectural Lighting

While modern lighting design strives for high visual impact, traditional RGB systems have inherent limitations regarding color reproduction and the uniformity of color mixing. In response, providers of lighting solutions are increasingly adopting products equipped with full-spectrum LED technology.

The ams OSRAM OSLON™ Pure 1414 high-performance full-spectrum LED covers the entire visible light spectrum-from 450nm to 630nm-while featuring an ultra-compact package and high luminous flux output. Compared to traditional RGB LED solutions, the OSLON™ Pure 1414 LED offers a Color Rendering Index (CRI) of over 95, with a single-white color temperature range spanning from 1800K to 6500K. This enables the faithful reproduction of an object's true colors and textures-whether for stage lighting at large-scale events, dynamic projections on architectural facades, or atmospheric lighting for cultural tourism and night-time attractions. This full-spectrum solution ensures that every illuminated space reflects the exact colors envisioned by the designer; such color precision is precisely what distinguishes a spectacular visual feast from an ordinary event.

02 Seven-Primary-Color Solution: Unlocking Boundless Creativity Through Rich Color Combinations

With its diverse range of color options, the ams OSRAM OSLON™ Pure 1414 serves as the foundational building block for multi-primary-color lighting systems.

Measuring just 1.4mm × 1.4mm, this ultra-compact, high-brightness LED functions as a chip-level Lambertian emitter, delivering exceptional lumen density and color uniformity within a small footprint. The series encompasses a full spectrum of colors-from blue to red-utilizing both direct-emission and phosphor-converted technologies. This allows for the creation of seven-primary-color lighting systems tailored to specific customer requirements. The uniform package size ensures consistency across different colors, facilitating tight spacing and multi-channel color mixing. Furthermore, the Lambertian emission characteristic provides a 120° beam angle, ensuring smooth, seamless color blending.

The 1.4mm × 1.4mm ultra-small package of the OSLON™ Pure 1414 is particularly critical for seven-primary-color systems, which require the integration of multiple color channels within a confined space. Its compact size allows for a higher density of LEDs on a given PCB area, enabling "tight clustering" of various colors. The small light-emitting surface also simplifies secondary optical design, enhancing beam control while simultaneously reducing the cost of the overall optical system. Leveraging the diverse color palette of the ams OSRAM OSLON™ Pure 1414 series, Liangmeiji has pioneered a seven-primary-color (RGBWCLA) solution. This system reconstructs the full solar spectrum, spanning the 400–760nm visible wavelength range. By selecting seven foundational colors based on precise chromaticity coordinates, the solution achieves a significantly broader color gamut.

This enables Liangmeiji's products to produce not only the full spectrum from blue to red-and a vast array of combinations beyond-but also to deliver the nuanced color transitions and highly saturated dynamic effects required for landscape lighting, stage performances, and immersive lighting installations-results that are difficult to attain with traditional RGB systems.

A representative from Liangmeiji noted:

"Our full-spectrum solution offers exceptional flexibility in color composition. We can select specific LED colors to align with a project's theme, or blend multiple colors to achieve the exact hues envisioned by designers. The ams OSRAM OSLON™ Pure 1414 is currently the most compact, mass-produced LED series with the widest color coverage on the market. Its superior color-mixing performance has also enabled us to achieve optical designs with narrower beam angles-a feat that was previously challenging to realize."

The core value of this solution lies in its unparalleled color flexibility:

• Wider Color Gamut: Spanning blue, cyan, true green, bright green, golden yellow, and red-complemented by white light with adjustable color temperatures-it far surpasses the color-expression capabilities of traditional RGB systems.

• Superior Color Rendering: The blended white light achieves a Color Rendering Index (CRI) of Ra > 95, ensuring the accurate reproduction of an object's true colors.

• Enhanced Customization: LED colors can be tailored to match the thematic requirements of a specific project, or blended to create any color desired by the designer.

03 From Wall Washers to Floodlights: An Innovative Product Portfolio

Built upon the high-performance ams OSRAM OSLON™ Pure 1414 LEDs, Liangmeiji has introduced two flagship products: the "Moyun" (Ink-Wash) L2710 full-spectrum wall washer and the "Geometry" L0350 full-spectrum floodlight. OSLON™ Pure 1414 combines high luminous flux output with excellent color-mixing capabilities. It enables more compact luminaire designs with smaller light-emitting surfaces, while minimizing the risk of color spots or fringes. This provides a solution for high-end lighting applications that balances superior color performance with engineering feasibility, broadening its utility across diverse settings-from premium venues and themed events to museum lighting.

OSLON™ Pure 1414 is certified for outdoor use, offering a long lifespan and high reliability. For long-term landscape and cultural tourism projects, this translates to lower failure rates, reduced maintenance costs, an extended product lifecycle, and consistent color performance even in demanding outdoor environments. This reliability serves as a strong foundation for Liangmeiji (亮美集) to expand into large-scale outdoor projects, helping their end clients build long-term confidence in product quality.

04 The Value of Innovative Collaboration and Future Implications

The partnership between ams OSRAM and Liangmeiji represents more than just the integration of light source technology and luminaire design; it offers an innovative paradigm for the industry:

• In terms of technical innovation: It validates the feasibility of pushing the boundaries of lighting performance through a richer range of spectral and color combinations, offering new perspectives for exploring next-generation, high-quality light source technologies.

• In terms of value creation: It reflects a broader evolution within the lighting industry-shifting from a focus on basic metrics like brightness and energy efficiency toward a greater emphasis on color quality, visual experience, and contextual value-providing valuable insights for future industry innovation.

The lighting industry is rapidly evolving from "simply illuminating a space" to "crafting an experience." The integration of full-spectrum light and multi-primary color tuning is emerging as a key technical direction for the high-end lighting market. The collaboration between ams OSRAM and Liangmeiji serves as a technical model for the rest of the industry.

As market demands for light quality continue to rise, full-spectrum, multi-primary color-tuning solutions will expand from flagship projects into a wider array of commercial applications. ams OSRAM remains committed to working alongside partners like Liangmeiji-using light to redefine the boundaries of what is possible in illumination.
