Embodiment Construction

[0037] Reference will now be made in detail to the preferred embodiments, examples of which are illustrated in the accompanying drawings. However, the embodiments can be modified into various other forms. The embodiments are not restrictive but illustrative. The embodiments are provided in order to more fully explain the present disclosure to those skilled in the art.

[0038] 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, or one or more intervening elements may also be present.

[0039] When an element is on an "on" or "under" side, "under the element" and "on the element" may be included based on the element.

[0040] In addition, terms such as "first", "second", "above / upper / above" and "below / lower / underneath" do not necessarily require or refer to any physical or logical relationship between such subjects or elements. The relative terms of " are only used to distinguish between...

Abstract

The present invention provides a light emitting device and a lighting device for a vehicle including the light emitting device. The light emitting device includes a light source unit for emitting a first excitation beam; a beam shape conversion unit for reflecting the first excitation beam and outputting the reflected first excitation beam as a second excitation beam; and a driving unit for driving the light source unit, wherein the beam shape conversion unit includes a plurality of reflective surfaces having different reflective patterns, and the reflective surfaces are arranged in a direction intersecting a direction in which the first excitation beam is incident.

Description

technical field [0001] Embodiments relate to a light emitting device and a lighting device for a vehicle including the light emitting device. Background technique [0002] A light emitting diode (LED) is a semiconductor device that converts electrical energy into infrared light or visible light by using the characteristics of compound semiconductors to transmit and receive signals or is used as a light source. [0003] Light emitting diodes and laser diodes do not contain environmentally harmful substances such as mercury (Hg) used in conventional lighting equipment such as incandescent or fluorescent lamps. Therefore, light emitting diodes and laser diodes are environmentally friendly. In addition, light emitting diodes and laser diodes exhibit long lifetimes and low power consumption. Therefore, light-emitting diodes or laser diodes have replaced traditional light sources. [0004] figure 1 is a view schematically showing a general headlight for a vehicle. [0005] Li...
