Abstract
An LED lamp is formed from a die substrate wherein the substrate has formed thereon a semiconductor material, an electrode for the application of a bias across the semiconductor material for causing light to be emitted therefrom, and an adhesive that bonds the die substrate to a support substrate, wherein the adhesive is a polymerized siloxane polymer having a thermal conductivity of greater than 0.1 watts per meter kelvin (W/(m·K)) wherein the adhesive is not light absorbing, wherein the siloxane polymer has silicon and oxygen in the polymer backbone, as well as aryl or alky groups bound thereto, and wherein the adhesive further comprises particles having an average particle size of less than 100 microns.
