Abstract
A system for removing snow and ice is provided. The system has a light head mounted to rotate. A light source is mounted in the light head and radiates visible light. An optical train is mounted in the light head adjacent the light source to focus the visible light to a concentrated light beam line that is directionally focused. A controller is in communication with the light head and is programmed to rotate the light head thereby sweeping the concentrated light beam along a surface.
Claims20
A system comprising:
- a light head mounted to rotate;
- a light source mounted in the light head and radiating visible light;
- an optical train mounted in the light head adjacent the light source to focus the visible light to a concentrated light beam line being directionally focused;
- and
- a controller in communication with the light head, the controller programmed to rotate the light head thereby sweeping the concentrated light beam along a surface.
2 more elements
A system comprising:
- a housing;
- a light source positioned in the housing and radiating generally diffuse visible light;
- an optical train mounted in the housing adjacent the light source to focus the diffuse visible light to a concentrated light beam line between a first optic and a final optic;
- and
- wherein the concentrated light beam has a concentrated power density at a focal distance from the final optic that is greater than a first power density at the first optic.
2 more elements
A system comprising:
- a housing with an ellipse portion and a tube portion;
- a light source mounted in the ellipse portion and radiating generally diffuse visible light;
- a reflector formed in the ellipse portion for reflecting the diffuse visible light from the light source;
- a first lens mounted in the tube portion and positioned at a major diameter of the reflector, wherein the reflector reflects the light toward the first lens, the first lens shaping the light in a line-shaped beam;
- and
- a second lens mounted in the tube portion, wherein the first lens projects the line-shaped beam toward the second lens, the second lens focusing the line-shaped beam to a concentrated beam having a concentrated power density at a second lens focal distance that is greater than a first power density at the first lens.
