Abstract

To provide a LED headlight structure that visually conveys a modern or stylish appearance to an observer, the LED headlight structure is characterized in that: a headlight PCB( 260 ) low beam and high beam headlight LED structures on at least one side of the motorcycle are mounted to one plate or in one plane such that high beam illumination is emitted at the inside of the motorcycle and low beam illumination is emitted at the outside of the motorcycle; an extension member ( 120 ) is positioned forward of the reflector assembly ( 140 ) and between a headlight case ( 104 ) and a headlight lens ( 102 ); and a window structure ( 122 ) configured for selectively passing portions of the low and the high beam illumination reflected by the reflector assembly is formed at the extension member ( 120 ).

First claim

1 . A light emitting diode (LED) headlight structure for a motorcycle having:
headlight LED elements for emitting low beam and high beam illumination, a headlight printed circuit board (PCB) to which said headlight LED elements are mounted, a reflector assembly having low and high beam reflectors, configured to reflect said low beam and high beam illumination emitted by said headlight LED elements toward the front of the motorcycle, said LED headlight structure constructed by combining said headlight PCB with an upper portion of said reflector assembly, said LED headlight structure positioned within a space connecting a headlight case and a headlight lens, and mounted on both sides of motorcycle, characterized in that: said headlight PCB mounts at least said headlight LED elements on one side of the motorcycle to one plate, said high beam illumination is emitted at the inside of the motorcycle and said low beam illumination is emitted at the outside of the motorcycle on one side of the motorcycle, an extension member is positioned forward of the reflector assembly and between said headlight case and said headlight lens, and a window structure is formed at said extension member, the window structure configured for passing portions of said low and high beam illumination reflected by the reflector assembly therethrough, wherein an upper border of said window structure is located close to an upper portion of the low beam reflector and is located below the high beam reflector, with respect to a front view of the motorcycle, and wherein the upper border of said window structure is oriented obliquely in a downward direction toward the inside of the motorcycle.

2 . The LED headlight structure of claim 1 , wherein the window structure is formed at both sides of the motorcycle and forms a generally rectangular shape expanding forward and to the outside of motorcycle, and wherein at an inside border and an upper or lower border of said window structure the LED headlight structure further comprises a light guide member that emits light.

3 . The LED headlight structure of claim 2 , wherein the light guide member emits light at two sides of the window structure and forms the lower border of the window structure.

4 . The LED headlight structure of claim 2 , further comprising light guide member LED elements, wherein a portion of the light guide member is positioned to receive light output by said light guide member LED elements, and wherein the light guide member on both sides of motorcycle is integrally formed.

5 . The LED headlight structure of claim 4 , wherein the light guide member includes a connecting portion for connecting to both inside borders of light guide member, and a wherein single PCB to which said light guide member LED elements are mounted is positioned close to said connecting portion of the light guide member.

6 . The LED headlight structure of claim 5 , wherein the motorcycle includes a front cover that covers and surrounds portions of the LED headlight structure, and which covers said connecting portion of the light guide member, said light guide member LED elements, and said single PCB.

7 . The LED headlight structure of claim 2 , wherein said light guide member has the function of a position light structure of the motorcycle.

8 . The LED headlight structure of claim 1 , wherein said window structure is positioned at both sides of the motorcycle and forms a generally rectangular shape expanding forward and to the outside of motorcycle and has light dispersion elements near an upper or lower border of said high beam reflector, and wherein the light dispersion elements are configured to receive and scatter the light reflected by said reflector assembly.

9 . The LED headlight structure of claim 8 , wherein said light dispersion elements are disposed on a lower border of the window structure corresponding to the high beam reflector.
