Abstract: A light deflection element is capable of deflecting incident light so as to follow a position of an observer and suppressing reduction in intensity of light that reaches eyes of the observer regardless of their position. The light deflection element includes: a first optical element configured to deflect incident light; a second optical element configured to change a deflection direction of emitted light by changing a refractive index thereof according to a voltage applied thereto; a third optical element; and a control section configured to control the voltage applied to the second optical element. At least one of interfaces between the first and second optical elements and the second and third optical elements is an aspheric surface. The aspheric surface has an optical power that compensates enlargement of the emitted light which is caused by refractive index distribution caused when a voltage is applied to the second optical element.

Abstract: A lighting device includes a light emitting element; a first lens that captures and emits light generated by the light emitting element; and a second lens that captures light emitted from the first lens and emits the light in a predetermined direction. The first lens includes a first-lens-entrance through which the light generated by the light emitting element enters, a first lens exit that emits the light entered from the first-lens-entrance and transmitted through an inside of the first lens, and a plurality of first-lens-side-portion-wall-surfaces that are provided between the first-lens-entrance and the first lens exit. The plurality of first-lens-side-portion-wall-surfaces include a reflection-side-surface-portion that reflects the light entered the inside of the first lens from the first-lens-entrance, and a side surface portion that is configured to allow light having a luminous intensity smaller than a luminous intensity of light entering the reflection-side-surface-portion to enter.

Abstract: A small and thin lighting device with high efficiency and good design and a headlight for a vehicle. A lighting device includes a first lens taking light generated by a light emitting device and emitting the light, and a second lens taking an emitted light from the first lens and emitting the light, in which the second lens is an anamorphic lens in which curvatures are different in a vertical direction and a right and left direction and a center of a lens surface in the vertical direction of the second lens is positioned in an upper direction with respect to an optical axis of the first lens. A headlight for a vehicle including the plural lighting devices is forming a low beam light distribution by superimposing lights from respective lighting devices for irradiation of the center, right and left in a horizontal direction respectively.
