Abstract:
(EN) Disclosed is a light emitting diode, capable of increasing forward effective light output and/or reflecting oblique incident light with the maximum effect by means of a combined DBR structure. According to one embodiment of the present invention, the light emitting diode comprises a light emitting epitaxial laminated layer having opposite first and second surfaces and comprising an N type limiting layer, an active layer, and a P type limiting layer. The first surface is a light exiting surface; the lower surface of the epitaxial laminated layer is configured to be in a combined DBR structure combined by N groups of DBR sub-layers; counting from the first pair of DBR sub-layers adjacent to the active layer among the N groups of DBR sub-layers, a central reflection wavelength of each group of DBR sub-layers is separately λ, λ+λ0, λ+2λ0, , λ+(N-1)*λ0, λ being a light emitting wavelength of the active layer, (N-1)*λ0 being the maximum blue shift generated by oblique incidence of the active layer, and λ0 being greater than 0.
(FR) L'invention concerne une diode électroluminescente pouvant augmenter la sortie de lumière effective vers l'avant et/ou réfléchir la lumière incidente oblique avec un effet maximum au moyen d'une structure DBR combinée. Selon un mode de réalisation de la présente invention, la diode électroluminescente comprend une couche stratifiée épitaxiale électroluminescente ayant des première et seconde surfaces opposées et comprenant une couche de limitation de type N, une couche active et une couche de limitation de type P. La première surface est une surface de sortie de lumière ; la surface inférieure de la couche stratifiée épitaxiale est conçue pour être dans une structure DBR combinée combinée par N groupes de sous-couches DBR ; en comptant à partir de la première paire de sous-couches DBR se trouvant à proximité de la couche active parmi les N groupes de sous-couches DBR, une longueur d'onde de réflexion centrale de chaque groupe de sous-couches DBR est séparément λ, λ+λ0, λ+2λ0, λ+(N-1)*λ0, λ étant une longueur d'onde d'émission de lumière de la couche active, (N-1)*λ0 étant le décalage maximal vers le bleu généré par l'incidence oblique de la couche active, et λ0 étant supérieur à 0.
