Compared to lateral LED, the vertical LED (VLED) is superior for high power applications. Higher power, efficiency, reduced current congestion, better light extraction, and better heat sinking are just a few of the advantages of VLED.
Using a high electrical and heat conductive substance, the vertical LED method Bonds the second substrate. Also capable of removing the substrate, forming the electrode, and chip shaping
The primary vertical LED technologies include substrate removal, bonding a second conductive substrate, the deposition of reflecting metal, and surface treatment to enhance light extraction.
The primary uses are for outdoor and indoor lighting, flash, auto headlights, and traffic signals.
The Global Vertical LED chip market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The new Luxeon 5050 mid-power packaged LED has been added to Lumileds’ range for outdoor SSL and high-output industrial SSL solutions.
The Lumileds LED produces 350 lm at 2W and has an efficiency of 175 lm/W. That performance is for a 4000K-CCT LED operating at 85°C with a 70 CRI.
Although Lumileds will provide products with CCT as low as 2700K and CRI as high as 90, the lighting utilised in the target applications typically has a cool CCT and moderate colour performance.
In the flip-chip architecture, the electrodes are on the bottom surface for a simpler and more reliable connection to the package substrate, while the surface next to the growth substrate becomes the light-emitting surface.
