Description
1W Power LED Light Source is a high performance energy efficient device which can handle high thermal and high driving current. The exposed pad design has excellent heat transfer from the package to the motherboard. The Warm White Power LED is available in various color temperature ranging from 2600K to 4000K. The product has high Color Rendering Index (CRI) which provides excellent color perception and visual clarity. The low profile package design is suitable for a wide variety of applications especially where height is a constraint. The package is compatible with reflow soldering process. This will give more freedom and flexibility to the light source designer.
