A method for distributing fluorescence onto a light emitting diode chip includes steps: providing a base; mounting the LED chip having a light-emergent face on the base; disposing a baffle sleeve on the base whereby the baffle sleeve surrounds the LED chip; disposing a solid fusible block with the fluorescence mixed therein on the LED chip; heating the solid fusible block to be in a liquid state, and the fusible block flowing over the light-emergent face of the LED chip; and cooling the fusible block to be in a solid state again.
