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. ## Claims ### Claim 1 An illuminating device, comprising: light emitting diodes; a first lens array including first lenses individually corresponding to the light emitting diodes; a light control member including light transmission channels individually corresponding to the first lenses and a light blocker surrounding the light transmission channels; and a second lens array including second lenses individually corresponding to the light transmission channels, each of the first lenses including: a light concentrator for producing concentrated light by concentrating a part of light emitted from a corresponding light emitting diode of the light emitting diodes; and a reflector surrounding the light concentrator to produce reflected light by reflecting another part of the light emitted from the corresponding light emitting diode in a direction across the concentrated light, each of the first lenses being configured to output illumination light including the concentrated light and the reflected light produced from the corresponding light emitting diode, each of the light transmission channels including: a first light transmission channel facing the first lens array to transmit the illumination light output from a corresponding first lens of the first lenses;
