Abstract:
A device to produce a bright light for use in non-lethally dispersing birds from a preselected area, comprising:at least one laser diode light source, said at least one laser diode light source capable of producing a beam of light within a wavelength region of 400-700 nanometers;. a housing, said housing being transparent to light at said wavelength region; a rotatable member extending within said housing; said at least one laser diode light source being mounted upon said rotatable member; means for periodically activating said at least one laser diode light source; means operably connected to said rotatable member for controllably regulating the rotation of said rotatable member such that said rotatable member may be rotated in a predetermined or random fashion; and said at least one laser diode light source having means associated therewith for limiting the intensity of the at least one laser diode output beam to fall below the Maximum Permissible Exposure (MPE) as recognized by the American National Standards Institute in order to prevent eye damage to humans; whereby said device can be readily placed or mounted within the vicinity of birds to be dispersed.
