Light Modeling

A multi-chip white-light modeling algorithm for high color rendering index and high color uniformity of surface mounted LED devices is demonstrated. The simulation of white-light LED model, according to the principle of additive color mixture by four color of red, amber, green, blue LEDs and using the commercial software program to perform Monte Carlo ray tracing has been developed. The simulation and experimental results show that the performance can be achieved with a number of LED chips.

High speed photography using the Cranz-Schardin camera was performed to study the crack divergence and divergence angle in thermally tempered glass. A tempered 3.5 mm thick glass plate was used as a specimen. It was shown that two types of bifurcation and branching existed as the crack divergence. The divergence angle was smaller than the value calculated from the principle of optimal design and showed an acute angle.
