Abstract
A light source is constituted by a plurality of light emitting units which are arranged opposite to a light irradiating lens such that light emission from a part of the light source is changed to light emission from the whole surface of the light source and vice versa. In addition, a light irradiating apparatus having a light emitting diode used therefor as a light source comprises optical fiber(s) arranged between the light emitting diode and a light emitting lens such that a light emitted from the light emitting diode can be conducted to the light irradiating lens is disclosed. One end of each optical fiber is located at the position in the vicinity of the light emitting diode and other end of the same is located at the position substantially coincident with the focus of the light irradiating lens. In another embodiment, an optical fiber employable for an optical radar system has an outlet end of the optical fiber which is formed by two inclined surfaces in a wedge-shaped configuration. An inlet end of the optical fiber is formed at a right angle relative to an optical axis of the optical fiber.
