Abstract

A light emitting device may be provided that includes: a substrate; a body which is disposed on the substrate and has a first hole having a predetermined size; a light emitting chip which is disposed within a cavity formed by the substrate and the first hole of the body; a cap which is disposed on the body and has a second hole having a predetermined size; and a transparent window which is disposed in the second hole, wherein a lower portion of the cap is divided into a first surface and a second surface more projecting downwardly than the first surface and wherein at least a portion of the first surface is attached and fixed to the body.

Description

[0001] This application is a divisional application of an invention patent application with the application number 201310346581.X, the application date is August 9, 2013, and the invention name is "light emitting device". technical field [0002] This embodiment relates to a light emitting device. Background technique [0003] With the development of both thin film growth technology and constituent materials, light-emitting devices (including laser diodes or light-emitting diodes) formed by using Group III to Group V or Group II to Group VI compound semiconductor materials of semiconductors can produce various Different colors of light (such as red light, green light, blue light) and ultraviolet light. Light emitting devices are also capable of producing highly efficient white light by using fluorescent materials or by mixing these colors. Compared with existing light sources such as fluorescent lamps and incandescent lamps, the light emitting device has advantages of low p...
