Product Description

High Brightness Wide-Viewing-Angle 4-mm Oval LED as Screen Master

Product Description

These oval LEDs(Single color, Red/Green/Blue) are specially engineered for high-performance full-color displays, including digital billboards, video screens, and passenger information systems. Their unique oval radiation pattern delivers superior luminous intensity, making them ideal for outdoor applications-whether optimizing visibility in bright sunlight or enabling energy-efficient operation for low-power consumption requirements.

These high-performance LEDs feature an advanced optical-grade epoxy encapsulation, delivering exceptional resistance to extreme temperatures and moisture for reliable outdoor operation in traffic signals and signage applications. The UV-resistant formulation of the encapsulation resin significantly minimizes degradation from prolonged sunlight exposure, ensuring long-term durability and color stability.
