Adjustable headlight device

An adjustable headlight device, comprising:

• a lens, having a light input portion and a light output portion, the light input portion has a plane surface and the light output portion has a curved ring surface or each of the light input portion and the light output portion has a curved ring surface, the curved ring surface is a cylindrical surface or a curved ring spherical surface or the curved ring surface is cylindrical aspherical surface or curved ring aspherical surface;
• a light reflection control set, including a first light reflection member and a second light reflection member, the first light reflection member is arranged under the lens, the first light reflection member has a first reflection portion arranged toward the light input portion, the second light reflection member is arranged at one side of the light input portion, the second light reflection member has a second reflection portion arranged toward the light input portion;
• and
• a light emitting diode, arranged between the first light reflection member and the second light reflection member, the light emitting diode is arranged adjacent to the first light reflection member, the light emitting diode is generated a light beam and clockwise rotated an angle θ;
• wherein the first light reflection member and the second light reflection member of the light reflection control set are configured to reduce a transmission distance of the light beam with light reflection principle and the adjustable headlight device is adjusted so that the angle of the light beam emitted from the light output portion is changed and a lighting distance of the adjustable headlight device is controlled.
