Electronic device
An electronic device includes a light emitting unit and a light controlling means. The light controlling means is disposed on the light emitting unit, wherein an included angle of an emitting light of the light emitting unit which at least passes through the light controlling means along a horizontal direction is greater than an included angle of the emitting light of the light emitting unit which at least passes through the light controlling means along a vertical direction. The horizontal direction is defined as a direction parallel to a floor and the vertical direction is defined as a direction perpendicular to the floor.
1. An electronic device, comprising:
a light emitting unit; and
a light controlling structure disposed on the light emitting unit, wherein an included angle of an emitting light of the light emitting unit which at least passes through the light controlling structure along a horizontal direction is greater than an included angle of the emitting light of the light emitting unit which at least passes through the light controlling structure along a vertical direction;
wherein the horizontal direction is defined as a direction parallel to a floor and the vertical direction is defined as a direction perpendicular to the floor;
wherein the light controlling structure is a non-adjustable collimator.
