Abstract:
1. A method for manufacturing a reflective plate, comprising: providing a heat dissipation plate of a high heat conductivity material having a first heat conductivity; placing an adhesive on the high heat conductivity material; forming a reflective material having a second heat conductivity on the adhesive; and coating a plurality of diffusion beads in a diffusion material on the reflective material, to have an uneven surface with a groove-protrusion shape, wherein the first heat conductivity is greater than the second heat conductivity, wherein the adhesive has a small refractive index between the high heat conductivity material and the reflective material, and bonds the high heat conductivity material and the reflective material; and wherein the adhesive is formed of TPFE that has a refractive index of 1.31 when a wavelength is 589.3 nm.
