Introduction
RGBACL (Red, Green, Blue, Amber, Cyan, Lime) lighting technology represents a significant advancement in the Film and TV industry, offering enhanced color reproduction and flexibility. However, the market currently offers only a limited selection of RGBACL spotlights. This article explores the current market status, the challenges in developing RGBACL lights, and how to choose good RGBACL lights to sell or use.
Current RGBACL Spotlights in the Market
There are many RGBWW lighting fixtures on the market. However, the market for professional RGBACL spotlights is relatively small, with only a few brands offering these advanced lighting solutions. Presently, the notable RGBACL spotlights include ARRI Orbiter; Kelvin Epos 300/600; Prolycht Orion 300FS/675FS (discontinued); Nanlux Evoke 900C. Furthermore, some of these products are already facing challenging after-sales issues because of the color shift. The development of RGBACL lighting has been slow. This is due to several technical and manufacturing challenges that need to be addressed.
Challenges in Developing RGBACL Spotlights
Limited Availability of High-Quality Six-Color Light Sources
One of the primary challenges in developing RGBACL lights is the scarcity of high-quality six-color light sources. The specific LEDs required for RGBACL lighting need to meet stringent criteria for brightness, consistency, and longevity, which are not widely available on the market.
Complexity of Six-Color Mixing Algorithms
Developing software algorithms capable of effectively mixing six different colors is significantly more complex than traditional RGB or RGBW systems. These algorithms must ensure accurate color rendering and smooth transitions, which requires extensive research and development.
Consistency of LEDs
Ensuring the consistency of LEDs is another significant hurdle. Inconsistent LEDs can lead to variations in color output, making it difficult to achieve precise color matching. This inconsistency can result in visible color shifts, which are unacceptable in professional film and TV production.
LED Light Source Degradation
Over time, LEDs can suffer from light degradation, leading to color inaccuracies. This phenomenon, known as “color shift,” poses a considerable challenge for maintaining the long-term reliability of RGBACL lights. Ensuring that these lights continue to perform accurately over their lifespan requires ongoing innovation and quality control.
The Challenge of Phosphor-Based LEDs
Many LED light sources use a technology called “phosphor coating,” where the LEDs are coated with phosphor materials. This technique can lead to significant light decay over time.
- Light Decay Impact on Bi-Color Lights: For bi-color lights, this is manageable as users can adjust the color temperature to compensate for the decay.
- Light Decay Impact on RGBACL Lights: For RGBACL lights, this decay is more problematic because precise color mixing from six different LEDs is required. Any degradation in one LED affects the overall color accuracy, making it difficult to achieve the desired lighting effects.
- Inconsistent Color Output: Phosphor-coated LEDs can exhibit variability in their color output, which complicates the creation of consistent and accurate lighting, especially critical in professional film and TV production.
The Solution of Phosphor-Free LEDs
To overcome these challenges, we have opted not to use phosphor-coated LEDs for our RGBACL lights. Instead, we have adopted custom-made Kyocera phosphor-free LEDs. These Kyocera chips are designed to maintain consistent color output over time, significantly reducing the risk of light decay and ensuring long-term color accuracy.
The use of Kyocera phosphor-free LEDs addresses several key issues:
- Enhanced Longevity: These LEDs are less prone to the degradation that affects phosphor-coated LEDs, ensuring that the lights remain reliable and accurate over longer periods.
- Consistency in Color Output: By avoiding phosphor coating, we can ensure that each LED maintains its original color properties, which is crucial for accurate color mixing in RGBACL applications.
- Reduced Maintenance: With less light decay, our RGBACL lights will require less frequent recalibration and maintenance, providing a more stable and dependable solution for professional film and TV productions.
How to Choose RGBACL Spotlights to Sell or Use
When selecting RGBACL spotlights, whether for resale or use in production, consider the following factors to ensure you choose the best quality products:
Color Accuracy
- Testing: Ensure that the RGBACL spotlights you choose have been rigorously tested for color accuracy. This is crucial for achieving the precise color reproduction needed in professional film and TV production.
Ease of Software Control
- User-Friendly Interface: The software controlling the RGBACL lights should be intuitive and easy to learn. This ensures that users can quickly master the controls and make precise adjustments as needed.
Quality of LEDs
- Phosphor-Free LEDs: Opt for spotlights that use high-quality phosphor-free LEDs from reputable brands, such as Kyocera, Osram, and CREE. These LEDs offer superior consistency and longevity, reducing the risk of light decay and color shift over time.
By focusing on these key aspects, you can ensure that you are selecting high-quality RGBACL spotlights that will meet the demanding requirements of the Film and TV industry.
Conclusion
While the current market for RGBACL spotlights is limited and development has been slow due to various challenges, the future is bright. Ongoing research and development efforts by light source manufacturers and lighting companies are set to revolutionize the industry. In the coming years, we can look forward to a wider selection of high-quality RGBACL lights that will offer filmmakers and TV producers unparalleled color control and accuracy.
