MicroLEDs: from Headlamps to the Data Center

When we think about the evolution of AI technology, developments in machine learning and large language models come readily to mind, as do the latest graphics processing units (GPUs), high-bandwidth memory (HBM), and exotic semiconductor technologies such as chiplets and heterogeneous integration.  But car headlamps? Automotive lighting is not usually seen as an inspiration for the next big thing in AI. Interestingly however, high-tech ‘adaptive beam’ front lights are proving the reliability and scalability of a valuable optical connectivity technology which could help data center operators to meet today’s challenges of increasing network bandwidth, efficiency and reliability. But let’s take a step back to understand how headlamps could possibly be relevant to the technology of AI data centers at: [News] MicroLEDs: from Headlamps to the Data Center – LEDinside

Introducing the World’s First Lensless LED Headlight: A New Era in Automotive Lighting

At ORACLE Lighting, we’re proud to unveil our most groundbreaking innovation yet: the world’s first lensless LED headlight—a revolutionary product that’s about to disrupt everything you thought you knew about headlight design.  Our new lensless LED headlight eliminates the lens entirely, removing the most failure-prone element of the system. This cutting-edge design is made possible by modular Bi-LED emitter pods with innovative features such as IP68 ingress protection and active thermal management. Each LED component—from the DRL to the high and low beams—is fully serviceable and replaceable, giving users and installers a dramatically improved ownership experience.  [News] Introducing the World’s First Lensless LED Headlight: A New Era in Automotive Lighting – LEDinside

The Statue of Liberty was made with copper but due to oxidation, it turned green.

When the “Lady in the Harbor” first arrived in New York in 1886, she didn’t look like the mint-green icon we know today. In fact, for the first twenty years of her life, she stood as a towering, metallic beacon of reddish-gold. Designed by French sculptor Frédéric Auguste Bartholdi and engineered by Alexandre Gustave Eiffel, the statue was a gift from France to America. To build her, Bartholdi chose copper for three practical reasons:

  • Malleability:It could be hammered into elaborate, thin sheets.
  • Weight:Copper is lighter than stone or bronze, making it easier to ship 350 individual pieces across the Atlantic.
  • Durability:It was strong enough to survive a 27-day ocean voyage and the harsh winds of the harbor.

When she was unveiled on October 28, 1886, her skin—made of 300 copper sheets roughly the thickness of two pennies—shone with a bright, metallic brown luster. The transformation from “penny-colored” to “patina-green” wasn’t planned. Bartholdi actually expected the statue to age into a deeper, darker red. However, the unique environment of New York Harbor—a mix of salt air, moisture, and industrial pollution—triggered a process called oxidation.

The Timeline of Change:

  1. 1886–1900:The bright copper dulled into a dark, muddy brown.
  2. 1903:The first hints of a light green crust, or “patina,” began to appear.
  3. 1906:The color change was so controversial that Congress nearly stepped in. They appropriated $62,000 to paint the statue back to its original color, but the public protested, calling the idea “sacrilege.”
  4. 1910–1920:The statue was a patchy mix of brown and green until 1920, when the oxidation was complete, leaving her entirely teal.

While we now view the green color as iconic, it actually serves a vital structural purpose. The layer of verdigris (the green patina) acts as a protective shield. It seals the copper underneath, preventing the metal from further corrosion and weathering.  By the time the color fully changed, a new generation of immigrants had arrived in America seeing a green statue.
