Deep Dimming LED Solution for Architectural Lighting
Deep Dimming Solutions for High-End Architectural Lighting |
| As a Technical Marketing Manager at Future Lighting Solutions, I'm excited to share with you the latest innovation in LED technology - Lumilux's Luxion 3030HE Plus deep dimming LED. This game-changing solution addresses the long-standing challenges faced by architectural lighting OEMs when it comes to quality of light, performance, reliability, and press competitiveness. |
Quality of Light: A Key Attribute |
| When selecting an LED for high-end architectural lighting applications, quality of light is a top priority. This encompasses not only color rendering and spectrum-based metrics but also flux and color uniformity. To achieve this, LEDs are typically binned at their typical current for flux and VF (forward voltage) to minimize variations. |
| However, even with binning, LEDs can still exhibit significant variation at low currents, leading to unacceptable string-to-string and board-to-board uniformity. This issue is exacerbated by the increasing adoption of 1% dimming drivers in these applications. |
The Challenge of Dimming |
| To illustrate this challenge, consider a scenario where boards are populated with LEDs binned only at their nominal current. At low currents, these LEDs exhibit large VF variations, resulting in non-uniform and unacceptable lighting for high-end architectural fixtures. |
Lumilux's Luxion 3030HE Plus: A Breakthrough Solution |
| Lumilux has addressed this issue with the introduction of their Luxion 3030HE Plus deep dimming portfolio. Using an innovative, industry-leading process, Lumilux ensures that LEDs are tightly matched in VF throughout their operating range, minimizing potential variation between strings or boards. |
| The color point is also extremely consistent throughout the current range, eliminating any color shift when dimming. Furthermore, Lumilux guarantees very tight tolerance on these parts for flux and color, with only two flux bins (each 1.5 lumens wide) and three-step color binning as standard. |
Benefits of Luxion 3030HE Plus |
| The adoption of Lumilux's Luxion 3030HE Plus deep dimming LEDs offers several benefits, including: |
- High-quality uniform luminaires even at 1% dimming
- Mitigation of the need for VF testing, binning, and labeling at the board level
- Avoidance of long production delays from mismatched boards
- Reduced complexity, time, and cost in manufacturing luminaires
|
Conclusion |
| If you've experienced issues with flux uniformity in your fixtures, we invite you to contact Future Lighting Solutions and Lumilux sales representatives for a personalized demonstration of this innovative technology. With the Luxion 3030HE Plus deep dimming LED, Lumilux is setting a new standard for quality of light in high-end architectural lighting applications. |
| LED Lighting |
Light Emitting Diode (LED) lighting is a type of lighting that uses light-emitting diodes as its source of illumination. LEDs are semiconductor devices that produce light when an electric current passes through them. |
| Background |
The concept of LED lighting dates back to the early 20th century, but it wasn't until the 1960s that the first practical LEDs were developed. The first high-brightness LED was invented in 1995 by Shuji Nakamura, a Japanese engineer. Since then, LED technology has rapidly advanced, leading to the development of high-efficiency and high-color-rendering-index (CRI) LEDs. |
| How it Works |
An LED lighting system consists of an LED chip, a driver, and sometimes additional components such as lenses or reflectors. When an electric current is passed through the LED chip, it excites the semiconductor material, causing it to release energy in the form of light. |
| Advantages |
LED lighting has several advantages over traditional lighting sources, including:
- Energy efficiency: LEDs use significantly less energy than incandescent bulbs and can last up to 50 times longer.
- Long lifespan: LEDs have a long lifespan of around 25,000-50,000 hours or more, compared to traditional lighting sources which may need to be replaced every few thousand hours.
- Durable: LEDs are resistant to shock, vibration, and extreme temperatures.
- Environmentally friendly: LEDs contain no toxic chemicals such as mercury or lead, making them a safer choice for the environment.
