Title:
ULTRAVIOLET LIGHT DEVICE PACKAGE
Document Type and Number:
WIPO Patent Application WO/2020/040143
Kind Code:
A1
Abstract:
[Problem] To obtain an optical member having a desired shape in an ultraviolet light device package and to bond the optical member to a ceramic substrate in a small number of steps, thereby achieving high sealing performance. [Solution] An ultraviolet light device package 1 is provided with: a light-emitting device 2 for emitting ultraviolet light; a substrate 3 on which the light-emitting device 2 is mounted; and an optical member 4 that is disposed at a position facing the light-emitting device 2. The optical member 4 is formed of glass having a softening point of 1000°C or less, the external shape of the surface confronting the substrate 3 is circular, and the optical member 4 is bonded to the substrate 3 with a metal pedestal 5 interposed therebetween, said metal pedestal 5 being sealed and bonded to the optical member 4. The pedestal 5 has an upper-surface opening 51 that is circular in plan view and into which the optical member 4 is fitted. With this configuration, the upper-surface opening 51 of the pedestal 5 is circular in plan view, and therefore, when the glass constituting the optical member 4 is melted and bonded, the glass is made to have a uniform thickness by uniformly stretching and holding the radially spreading glass. This makes it possible to achieve an airtight glass sealed section having high sealing performance.
