Provided is a polyester resin composition, for a lighting fixture component, comprising 35-80% by mass of a polyethylene terephthalate resin (A) with 25 eq/t or less of terminal carboxylic acid groups, 0-10% by mass of a polyester elastomer (B), 0.05-3% by mass of an organic crystallization promoter (C) that does not contain alkali metal salts, 0.05-8% by mass of an inorganic crystallization promoter (D), 0.05-5% by mass of a polycarbodiimide compound (E), and 5-60% by mass of an inorganic fibrous reinforcing agent (F), wherein not only can clouding of glass surfaces or reflectors of the lighting fixture be prevented even when exposed to high-temperature environments, but formability is superior without a drop in crystallization speed, and the composition further has superior snap-fitting properties that facilitate mounting of the lamp section. |
