FIELD: electricity.
SUBSTANCE: invention relates to the field of lighting equipment. Technical result is improvement of lighting efficiency for portable lighting devices. The claimed lighting device has a scrolling function that provides lighting of the observed area at which the user is concentrated at present and the lighted area is scrolled forward and backward during reading. The lighting device contains two varieties of light-emitting units, an illuminating substrate, a controller and a selector. The selector controls one variety of the light-emitting units which illuminate a part of the illuminating substrate capable to deflect light to a part of the observed surface.
EFFECT: selector is intended to select an operating mode for the lighting device in manual control mode and preset scrolling mode.
