TECHNOLOGY AIM

En se basant sur les principes fondamentaux de cube et de plaquette LED, notre société a pour le but de développer la technologie avec laquelle nous pouvons fabriquer les produits très efficaces, fiables et compétitifs. Nous allons donc fournir une meilleure satisfaction des clients à travers l’optimisation de LED PKG et la conception préalable des applications.

Calculating LIFE Time based on decay of intensity after 2,000 Hours
 
Assuming the lifetime of LED is the period required to occur 50% decay of Intensity, the lifetime of ACROSENTEC 3 chip LED Module was given as following.
- Based on the Normal temperature : 65,000 Hours (About 7.5 years of continuous operating)
- Based on the High temperature-1(45℃) : 40,000 Hours (About 4.5 years of continuous operating)
- Based on the High temperature-2(60℃) : 27,000 Hours (About 3 years of continuous

※ This result is assuming the continuous operating (Always ON) condition.

Therefore, lifetime is increased according to the condition of non-continuous operating
(For example : operating at night only)
