Embodiment Construction

[0041] Reference will now be made in detail to the preferred embodiments, the accompanying drawings illustrating examples of the invention. However, the embodiments can be modified into various other forms. The examples are not restrictive but illustrative. The examples are provided to more fully explain the present disclosure to those of ordinary skill in the art.

[0042] It will be understood that when an element is referred to as being "on" or "under" another element, it can be directly on / under the element, and one or more intervening elements may also be present. When an element is referred to as being 'on' or 'under', 'under the element' and 'on the element' may be included based on the element.

[0043] Also, use of relative terms such as "first", "second", "upper / upper / above" and "lower / lower / under" is only used to distinguish one object or element from another object or element , without necessarily requiring or referring to any physical or logical relationship or...

Abstract

A light-emitting apparatus is disclosed. The light-emitting apparatus includes at least one light guide member, at least one light source unit disposed at at least one of two opposite end portions of the light guide member, a first reflection unit disposed on a first inner surface portion of the light guide member, and a plurality of light output units disposed on a second inner surface portion of the light guide member, located opposite the first inner surface portion, while being spaced apart from each other.

Description

technical field [0001] Embodiments relate to a light emitting device and a lighting device including the light emitting device. Background technique [0002] Light emitting devices are widely used in homes, industries and vehicles. For example, a halogen lamp, a high intensity discharge (HID) lamp, a xenon lamp, and a light emitting diode (LED) are used as a light source of a light emitting device installed in a headlight of a vehicle. In addition, laser diodes (LDs), which are next-generation light sources of light emitting devices, are attracting more and more attention. In the case where the LD is used for a vehicle, functional requirements such as long-distance irradiation and searchlight functions, design, and efficiency can be satisfied. The reason for this is that LDs have higher brightness than conventional light sources and occupy a smaller area than conventional light sources, and LDs exhibit unique characteristics such as flatness and polarization. Therefore, i...
