Abstract
(EN)
The light-emitting device is configured so that blue laser light emitted from a laser light source is input from the entrance face of an optical fiber and is emitted from the respective emission surfaces of branched first and second optical fibers. At the position facing the emission surface of the first optical fiber, a first light guide is disposed. In the process of guiding the laser light that has been input into the entrance face, a fluorophore layer is excited to generate a transformed light of a wavelength that differs from blue. The transformed light and the laser light are combined and emitted from the emission surface. At the position facing the emission surface of the second optical fiber, a second light guide is disposed. In the process of guiding the laser light that has been input into the entrance face, the light is scattered with a light-scattering processed section formed on the surface of the second light guide and is emitted from the emission surface.

Le dispositif électroluminescent est configuré de manière à ce qu'une lumière laser bleue émise par une source de lumière laser soit injectée depuis la face d'entrée d'une fibre optique et soit émise depuis les surfaces d'émission respectives de première et seconde fibres optiques ramifiées. Un premier guide de lumière est disposé à une position située en face de la surface d'émission de la première fibre optique. Lors du processus de guidage de la lumière laser ayant été injectée dans la face d'entrée, une couche de fluorophore est excitée afin de générer une lumière transformée ayant une longueur d'onde différente du bleu. La lumière transformée et la lumière laser sont combinées et émises depuis la surface d'émission. Un second guide de lumière est disposé à une position située en face de la surface d'émission de la seconde fibre optique. Lors du processus de guidage de la lumière laser ayant été injectée dans la face d'entrée, la lumière est diffusée avec une section de diffusion de lumière transformée formée sur la surface du second guide de lumière et est émise depuis la surface d'émission.

 レーザー光源から放出させた青色のレーザー光を、光学ファイバーの入光面から入光し、分岐された第1の光学ファイバーの放出面と第2の光学ファイバーの放出面からそれぞれ放出する。第1の光学ファイバーの放出面に対向する位置には第1の導光体を配置し、入光面に入光されたレーザー光を導光する過程で蛍光体層を励起し、青色とは異なる波長の変換光を生成し、この変換光とレーザー光とを合成し、放出面から放出する。第2の光学ファイバーの放出面に対向する位置には第2の導光体を配置し、入光面に入光されたレーザー光を導光する過程で、第2の導光体の表面に形成された光散乱加工処理部で散乱させて放出面から放出するようにした。
