A method for producing an LED includes steps of: providing a base (22), a chip body (21) and a die (40), wherein the base has a concave depression (23) defined therein and the die has a bottom wall (43) with an even surface having a surface roughness not smaller than 300 nanometers; disposing the chip body in the depression; heating a material which is used to seal the chip body on the base until the material is changed into liquid; pouring the liquefied material into the depression of the base; pressing the die toward a top surface of the liquefied material until the bottom wall of the die immerges in the top surface of the liquefied material; removing the die away from the depression when the liquefied material begins to cure; and (7) curing the liquefied material until all of it is solidified.
