Disclosed is an LED lamp based on transparent fluorescent ceramics. The LED lamp is composed of LED lamp filaments, electrode leads and a lampshade and is characterized in that the strip-shaped transparent fluorescent ceramics serve as the substrate of the LED lamp filaments, the width of the transparent fluorescent ceramics is equal to that of LED chips, then the blue LED chips (including leads) are sequentially fixed to the transparent fluorescent ceramic battens in an adhering mode, and identical transparent fluorescent ceramic strips adhere to the other sides of the LED chips or the other sides of the LED chips are coated with fluorescent optical cement. The transparent fluorescent ceramics can be Ce : YAG (including the situation when Ce ion concentration is zero), or Ce : Tb3Al5O12, or Ce, Cr : YAG, or Ce, Pr : YAG, or Ce : YAG+MgAl2O4, or Ce, Pr : YAG+MgAl2O4, or Ce, Cr : YAG +MgAl2O4. According to the LED lamp based on the transparent fluorescent ceramics, luminous decay of a fluorescent powder silica gel resin mixture phosphor can be effectively avoided, the performance of the LED lamp can be improved, and the service life of the LED lamp can be prolonged.
