Silica glass member for hermetic sealing of ultraviolet SMD type LED element and method of manufacturing quartz glass member for ultraviolet LED

摘要

A quartz glass member for airtight encapsulation of an ultraviolet SMD type LED element suitably used for airtight encapsulation and transparent window material of a surface mount type package (SMD) having an ultraviolet LED emitting a UV ray having a wavelength range of 200 nm to 350 nm do. Wherein the quartz glass member for airtight sealing is composed of a quartz glass base integrally formed with a uniform and unimpeded inner surface, and the quartz glass base has a first surface inside and a second surface opposite to the first surface, And a gas bonding plane for bonding to the outer circumferential bonding plane of the container is formed on an outer circumferential portion of the first surface and a second bonding surface for bonding the outer SMD LED element to the second outer surface corresponding to the first surface Shaped protrusions for processing the radiation of the light.
