| 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.
