Thermoplastic resin composition for light reflector, formed article for light reflector, light reflector, and method for producing formed article for light reflector
Thermoplastic resin composition for a light reflector such as a housing, reflector, and extension of an automotive lamp, and a lighting fixture. The composition contains 2 to 45 parts by mass of an inorganic filler treated with a fatty acid type surface treating agent and has an average diameter of not more than 3 m, per 100 parts by mass of a thermoplastic resin. The housing reflector made from such thermoplastic resin composition shows excellent surface smoothness, surface luster and surface image clarify.
INFRARED REFLECTING FILM
The invention relates to an infrared reflecting film comprising a flexible polymer substrate; a heat-mirror stack on the substrate, said heat-mirror stack comprising a first dielectric oxide layer, a second dielectric oxide layer and a silver-containing layer between the first and second dielectric oxide layers; and an optical stack on the heat mirror stack, said optical stack comprising alternating layers of at least one layer of a first type and at least one layer of a second type, wherein each layer of the first type has a refractive index measured at 550 nm of 1.6 or less and each layer of the second type has a refractive index measured at 550 nm of 2.3 or more.
Substrate-transferred stacked optical coatings
A method for manufacturing hybrid optical coatings and hybrid mirror assemblies, including: a) providing a first optical coating having layers of alternating high and low refractive indices of crystalline materials on a first host substrate via an epitaxial growth technique; b) providing a second optical coating having layers of alternating high and low refractive indices of dielectric materials on a second host substrate via a physical vapor deposition (PVD) technique; c) directly bonding the first optical coating to the second optical coating; and d) removing the first host substrate.
