    摘要: The present invention relates to a LED comprising at least one red light emitting and/or conversion layer, which emits light in the wavelength of ≥ 550 nm to ≤ 750 nm, preferably ≥ 630 nm to ≤ 700 nm, and/or at least one blue light emitting layer, which emits light in the wavelength of ≥ 400 nm to ≤ 550 nm, preferably ≥ 420 nm to ≤ 500 nm, and/or at least one green and/or yellow emitting luminescence material, which emits light in the wavelength ≥ 530 nm to ≤ 610 nm, whereby the at least one green and/or yellow emitting luminescence material is capable of absorbing light which is emitted by the at least one blue light emitting layer, characterized in that the red light emitting and/or conversion layer is made of a semiconductor material.
