lampshade structure

Abstract

A lampshade structure includes a light-transmitting outer shell and a heating element. The light-transmitting outer shell includes a spaced-apart inner surface and an outer surface. The heating element is directly transferred onto the light-transmitting outer shell using a substrate-free transfer process and includes a conductive layer and an adhesive layer made of a substrate-free colloid that fixes the conductive layer to the inner surface of the light-transmitting outer shell. This lampshade structure, through the substrate-free bonding design of the heating element, improves light transmittance and reliability, and provides efficient heat conduction to achieve snow melting.

Claims
