Abstract: An illuminating device includes: first lenses individually corresponding to LEDs; a light control member including light transmission channels individually corresponding to the first lenses and a light blocker surrounding the light transmission channels; and second lenses individually corresponding to the light transmission channels. Each first lens includes a light concentrator for producing concentrated light by concentrating light emitted from a corresponding LED, and a reflector surrounding the light concentrator to produce reflected light by reflecting light emitted from the corresponding LED in a direction across the concentrated light. Each first lens outputs illumination light including the concentrated light and the reflected light produced from the corresponding light emitting diode. Each light transmission channel transmits the illumination light output from a corresponding first lens. The light blocker prevents transmission of the illumination light emitted from each first lens. Each second lens refracts the illumination light transmitted by a corresponding light transmission channel.

Abstract: In a light source device, an axis extends from a light-emitting face and perpendicularly to the light-emitting face. A reflective surface includes a curved surface defined by rotating a first arc which is a part of an ellipse around the axis. The ellipse has a first focal point and a second focal point which are located on the light-emitting face. The second focal point is located adjacently to the first arc with respect to a center of the ellipse. A distance from the first focal point to the axis is shorter than a distance from the second focal point to the axis.
