Abstract
A thermosetting silicone resin composition for reflector of LED has an organopolysiloxane represented by the following average compositional formula, and has at least two alkenyl groups in one molecule, a linear organohydrogen polysiloxane represented by the following formula and/or a branched organohydrogenpolysiloxane represented by the following formula, an addition reaction catalyst, a white pigment selected from titanium oxide, zinc oxide, magnesium oxide, barium carbonate, magnesium silicate, zinc sulfate and barium sulfate, and an inorganic filler other than Component,RRR(OR)SiO  (1) RRHSiO  (3). There can be a thermosetting silicone resin composition which provides a cured product excellent in heat resistance and light resistance, less leakage of light to outside, and particularly suitable for a matrix array reflector.
