Embodiment Construction

[0037] Below, refer to Figure 1 ~ Figure 11B Examples of embodiments of the optical member and the transparent sealing member according to the present invention will be described.

[0038] like figure 1As shown, the optical component 10 according to this embodiment has: at least one optical element 12 that emits ultraviolet light; and a package 14 that accommodates the optical element 12 . The package 14 includes: a mounting substrate 16 on which the optical element 12 is mounted; and a transparent sealing member 20 bonded to the mounting substrate 16 via, for example, an organic adhesive layer 18 . The mounting substrate 16 is made of, for example, AlN (aluminum nitride). The transparent sealing member 20 is made of, for example, quartz glass or optical glass. As the adhesive layer 18 , an epoxy-based adhesive, a silicone-based adhesive, a polyurethane-based adhesive, or the like can be preferably used.

[0039] As described above, the optical element 12 is mounted on th...

Abstract

The present invention relates to an optical component and a transparent sealing member. An optical component (10) has: at least one optical element (12); and a package (14) that houses therein the optical element (12). The package (14) has: a mounting board (16) on which the optical element (12) is mounted; a transparent sealing member (20) bonded on the mounting board (16); a recessed section (26) surrounding the optical element (12) mounted on the mounting board (16); and a refractive index matching agent (28) applied to the inside of the recessed section (26). The package (14) has at leastone groove (30) in communication with the outside from the recessed section (26).

Description

technical field [0001] The present invention relates to an optical component and a transparent sealing member used for the optical component, for example, relates to an optical component and a transparent sealing component suitable for LED (light emitting diode), LD (semiconductor laser) and the like. Background technique [0002] In recent years, a method of using a light-emitting element (ultraviolet LED) that emits ultraviolet rays for sterilization or purification has become popular. In an ultraviolet LED device, a transparent sealing member is required in order to protect a light-emitting element from external air or moisture. Glass or quartz glass is used for the transparent sealing member from the viewpoint of ultraviolet light permeability and durability. [0003] Japanese Patent Application Laid-Open No. 2014-216532 discloses a semiconductor light-emitting element package, which has: a non-light-transmitting substrate on which a semiconductor light-emitting element...
