Abstract
An apparatus for preventing bird collisions with a window including a UV light source, a mask, and a first lens configured to direct UV light from the UV light source through the mask. The mask is at least partially transparent to UV light and includes a pattern that is at least partially opaque to UV light. The UV light passing through the mask contains the pattern. The pattern-containing UV light is projected onto a pane of glass to form a UV image visible to birds corresponding to the pattern on the pane. The image is configured to deter birds from flying into the pane of glass.
Claims18
An apparatus for preventing bird collisions with a window, the apparatus comprising:
- an ultraviolet (UV) light source;
- a mask that is at least partially transparent to UV light including a pattern that is at least partially opaque to UV light;
- a first lens configured to direct UV light from the UV light source through the mask, wherein the UV light passing through the mask contains the pattern, wherein the pattern-containing UV light is projected onto a pane of glass to form a UV image visible to birds corresponding to the pattern on the pane of glass and configured to deter birds from flying into the pane of glass;
- a first circuit comprising a first coil coupled to the UV light source;
- and
- a power circuit comprising a power supply and a second coil electromagnetically coupled to first circuit through the pane;
- wherein the power supply supplies an electric current to the second coil to induce a magnetic flux in the second coil and the magnetic flux from the second coil induces an electric current in the first coil.
A method of preventing bird collisions with a pane of glass, the method comprising:
- generating ultraviolet (UV) light at a UV light source;
- directing the UV light through a mask with a first lens, wherein the mask is at least partially transparent to UV light and includes a pattern that is at least partially opaque to UV light, the UV light passing through the mask including the pattern;
- and
- projecting the pattern-containing UV light onto a pane of glass to form an image visible to birds configured to deter birds from flying into the pane of glass, wherein projecting the pattern-containing light from the mirror onto the pane of glass comprises projecting the pattern-containing UV light at an angle of incidence to an exterior surface of the pane low enough to cause the pattern-containing light to reflect off of the exterior surface of the pane.
