A white light emitting diode, which comprises: an electrode bracket (1) made of physical composite material, a insulate spacer ball (2), a transparent cap (3), a LED die (6) for emitting blue or violet light, Ag glue (8) for adhering the LED die (6) in the cup on the upper portion of the electrode bracket (1) and a connecting wire (5) for connection of the LED die (6) and the electrode bracket (1). The white light emitting diode is characterized in that: the fluorescent powder layer (4) is coated on the inner surface of the transparent cap (3), the fluorescent powder layer (4) makes the blue or violet light emitted from the LED die (6) complemented with the light emitted by the fluorescent powder to form the white light. Furthermore, the transparent cap (3) is made of glass and the surface of insulate spacer ball (2) is coated with a reflective layer (7). |
