<p>PROBLEM TO BE SOLVED: To provide a polysiloxane composition capable of being applied to a light emitting diode element.SOLUTION: A polysiloxane composition capable of being applied to a light emitting diode element comprises (A) cage, net or chain polysiloxane containing alkenyl, (B) polysiloxane containing a silicon-hydrogen bond, (C) a combination of fillers with protection functions and (D) an alkene-hydrogen silylation reaction catalyst. The combination of the fillers with the protection functions can be selected from a material with high heat conductivity, a flame retardant, an anti-aging material, an ultraviolet-resistant material, a gas-barrier material, a thermal expansion inhibitor and/or a high-temperature-resistant material. The polysiloxane composition can be used in a material preparation of the base, reflector and/or packaging body of the light emitting diode element so as to effectively prolong the service life of the light emitting diode element and improve the stability of the light emitting diode element.</p> |
