2. Dam-ART™ COB LED Strip: Better Optical Control and a Refined Finish

Rishang has developed a broad range of Dam-ART™ COB LED strip lights to meet different lighting and control needs. The range includes white light, CCT, RGB, RGBW, SPI RGB individually addressable lighting, DTW, and ultra-narrow options.

This range supports a variety of applications, from linear lighting and commercial interiors to projects that require more precise control of light output.

The key feature is the dam structure, which helps keep the phosphor coating within the intended light-emitting area. This design creates a more controlled beam and a clean, well-defined product finish.

• A 115° beam angle: A narrower beam helps reduce light spill from the sides and directs more light toward the intended area.
• Approximately 20–30% higher front brightness: The focused output can provide higher front-facing brightness than conventional COB LED strip designs under comparable conditions.
• A clean, uniform appearance: The carefully formed silicone structure gives the strip a neat profile and a refined finish.
• A wide range of configurations: Options for different colors, control methods, and strip widths support a range of lighting designs.

Dam-ART™ COB LED strip lights are especially suitable for linear lighting, narrow light channels, and other installations where beam control and a clean appearance are important.

By combining optical design with a broad product range, Rishang continues to develop COB LED strip solutions for applications that call for both performance and a refined finish.

3. Full-Spectrum COB LED Strip: Bringing Colors Closer to Natural Light

Rishang’s full-spectrum COB LED strip is designed for indoor lighting applications where natural-looking colors and visual quality are important.

The strip achieves a general color rendering index of Ra ≥ 95 and special color rendering indices of R1–R15 ≥ 90 across all 15 standard test color samples. Key measurements include R9 for saturated red and R15 for light skin tones, helping the light render both objects and skin tones with greater accuracy.

These features make the strip suitable for retail displays, art venues, photography, and other applications where color appearance plays an important role.

The product also delivers strong results under the IES TM-30 color evaluation system:

• Rf ≥ 95: A high fidelity index, indicating that colors remain close to their reference appearance.
• Rg ≥ 100: A gamut index of at least 100, indicating that the overall color gamut is maintained or expanded relative to the reference.

Together, these measures help describe how faithfully the light renders colors and how it affects their overall appearance.

By combining high color rendering with a spectrum designed to stay close to natural light, Rishang offers a full-spectrum COB LED strip for projects that require accurate color, natural-looking materials, and a high-quality visual experience.

4. 160 lm/W High-Efficacy COB LED Strip: More Light with Less Energy
