Features

White LEDs for flash light source of mobile applications

  1. Provides a high color rendering index to improve the photo quality.
This product has an Ra* of 90 (lighting level at museum) to vividly reproduce colors close to that of natural light.
*Ra: Color rendering index. Indicates how accurately colors appear under a given light source.

■ Difference between a traditional flash and a high color rendering flash
When shooting with the "High color rendering flash," even in a dim room, skin tones are reproduced beautifully with rich warm colors.

optical simulation of high efficiency package structure

  1. Reflector structure optimized by optical simulation
  2. High-output white LED chip and high-reflectivity materials
  1. High heat dissipation and small size achieved by using a flat package.

10 C°/W achieved (Conventional: 30 C°/W)
High heat dissipation package



  1. Allows heat generated from white LED to be directly dissipated to the board.
  2. Optimized thermal dissipation path


  1. Unique sulfide barrier technology that shuts off the external air and prevents material degradation including blackening of Ag plating and moisture deterioration of the phosphor (under development).

Unique sulfide barrier technology provides high environmental immunity, independent of its location
