Light-emitting diode phosphors provide more diffuse light, which is desirable for many applications. Remote phosphor designs are also more tolerant of variations in the LED emissions spectrum. A common yellow phosphor material is cerium-doped yttrium aluminium garnet (Ce:YAG). White LEDs can also be made by coating near-ultraviolet (NUV) LEDs with a mixture of high-efficiency europium-based phosphors that emit red and blue, plus copper and aluminium-doped zinc sulfide (ZnS:Cu, Al) that emits green. This is a method analogous to the way fluorescent lamps work. This method is less efficient than blue LEDs with YAG:Ce phosphor, as the Stokes shift is larger, so more
Toyota Prius Plug-in Hybrid included charging cable connects to the charging port inlet located on the right-rear fender. The charge port location was moved from the front driver-side fender in the demonstration model based on input from the program participants. The battery charger cable weighs just , is in length, and fits in its own compartment in the trunk area. The charge port provides LED (Light Emitting Diode) illumination for convenient night-time charging. A timer allows charging to take place during off-peak hours and can be set for either a start or end time. According to Toyota the Prius plug-in was expected to be
