Development of lighting goggles with power white LED modules

Abstract

Everywhere in the world, the highest quality and quantity of lighting is required during the surgical operations. However, the surgical approach has had many types and various angles, common ceiling surgical halogen shadow less lighting system cannot provide an adequate amount of beams because the surgeons' heads hinder the illuminations from reaching the operation field. Therefore, we have designed surgical lighting system composed of white LEDs equipped on both sides of goggles. In fact, we succeeded in the first internal shunt operation in the left forearm using the surgical LED lighting sytem on 11th Sept 2000. In the operation with sitting position, it was about 34 cm from the operation field to the surgeon's eye point. Therefore, in the next approach, we have to try the operations with usual standing position. To get the more powerful LED light source, we have tried to make "power white LED module" composed with Nichia white LEDs (NCCx002) on AlN plate. Then we have tried the general thoracic operation with LED goggles composed "power white LED modules" on 9th December 2002.
