The present invention relates to a polyamide composition, comprising 30 to 97% by weight of (A) at least one semi-crystalline semi-aromatic polyamide, 2 to 50% by weight of (B) at least one white pigment, 0.1 to 2% by weight of (C) at least a phosphorus containing thermal stabilizer, 0.1 to 4.5% by weight of (D) at least one alkali salt with pH higher than 7, and optionally 0 to 50% by weight of (E) at least one filler, based on the total weight of the polyamide composition. The present invention shows an excellent initial reflectivity and a small drop of reflectivity after thermal aging at high testing temperature for a long while. Also, it has been found that the polyamide composition keeps balanced mechanical properties. The present invention also relates to a LED component made from the polyamide composition. It can be manufactured or assembled by reflow soldering processes.
