Development for new power white LED module with multifanctional printed-wiring board

In recent years, white LEDs and the applications are attracting attention as a replacement illumination lamp for the currently used fluorescent lamp, because white LEDs have several characteristics for low power consumption, simplification of circuitry, and longer life. While further research and development for miniaturization of lighting equipment and high discharge characteristics will be necessary in the immediate future. In this study, new multifunctional board specialized for three color power LED chips (red,green, blue) was developed, and power white LED module was assembled using the board. Lastly, several electro-optic properties were measured for new power white LED module. Based on these results, it was evaluated the power white LED module has high discharge characteristic and high luminous efficiency.
