Problems solved by technology

[0013] However, according to the prior art, there is a limitation in improving brightness due to technical difficulties in uniformly disposing a reflective layer around a light emitting device in a light emitting device package.
[0014] In addition, when a semiconductor device capable of supplying high power is required, although a semiconductor device capable of increasing power by applying a high power source has been studied, an appropriate solution has not yet been obtained

Abstract

An embodiment relates to a light emitting device, a method for manufacturing the light emitting device, a light emitting device package, and a lighting apparatus. The light emitting device package, according to an embodiment, can comprise: a package body (110) comprising frames (111, 112) and a body; a light emitting device (120) comprising first and second bonding parts (121, 122) so as to be arranged on the body (13); a reflective resin layer arranged between the light emitting device and the lateral side of a cavity (C) provided in the body; a transparent resin layer on the light emitting device; and a phosphor layer arranged on the transparent resin layer while being spaced from the light emitting device.

Description

technical field [0001] Embodiments relate to a semiconductor device package, a method of manufacturing the semiconductor device package, and a light source apparatus. Background technique [0002] Semiconductor devices including compounds such as GaN and ALGaN have many advantages such as wide and easily adjustable bandgap energy, so such devices can be variously used as light-emitting devices, light-receiving devices, and various diodes. [0003] In particular, due to the development of thin film growth technology and device materials, light-emitting devices (such as light-emitting diodes and laser diodes) obtained by using III-V or II-VI compound semiconductor substances can realize light with various wavelength bands, such as Red light, green light, blue light and ultraviolet light. In addition, light emitting devices such as light emitting diodes and laser diodes obtained by using III-V or II-VI compound semiconductor substances can realize white light sources with high...
