Abstract
A light-emitting diode (LED) light includes a ceramic shade, an illuminative unit and at least one wire. The ceramic shade includes a primary chamber defined therein and at least one through hole in communication with the primary chamber. The illuminative unit is disposed in the primary chamber and includes an LED die and a path. The path transfers heat generated by the LED die to the ceramic shade. The wire is connected to the illuminative unit and inserted through the through hole.

17. A method for making a ceramic shade comprising the steps of:
-
providing fluid ceramic paste by mixing ceramic powder with paraffin; making a semi-product of the ceramic shade by injecting the ceramic paste into a cavity of a mold so that the semi-product is made in compliance with the cavity of the mold; and making a final product of the ceramic shade by sintering the semi-product.
