Projection-type light

A light, comprising:

• a light source;
• a lens including a plurality of aspherical lenses each having an aspherical focus;
• and
• a reflector including a plurality of ellipse group reflector units having a common first focus located substantially at said light source and each reflector unit having a second focus forming a curved line and located substantially at a respective aspherical focus of corresponding aspherical lens.

A light, comprising:

• a light source;
• a lens including a plurality of aspherical lenses each having an aspherical focus;
• and
• a reflector including an ellipse group reflector unit that has an upper reflecting surface and a lower reflecting surface divided along a horizontal central line, wherein said upper reflecting surface ha an upper focus and said lower reflecting surface has a lower focus positioned at a different location from said upper focus.

A light, comprising:

• a light source;
• a lens including a plurality of aspherical lenses each having an aspherical focus;
• and
• a reflector including an ellipse group reflector unit having a plurality of reflecting surface segments, said reflecting surface segments having a common first focus located substantially at said light source and each of said reflecting surface segments having a second focus forming a curved line and located substantially at a respective aspherical focus of a corresponding aspherical lens as viewed in a horizontal cross sectional view, and each second focus being positioned above a horizontal center line of a corresponding aspherical lens as viewed in a vertical cross sectional view.

A light, comprising:

• a light source;
• a lens including a plurality of aspherical lenses each having an aspherical focus;
• and
• a reflector having an upper half portion and a lower half portion, said upper half portion including a rotated elliptical surface with a first upper focus located substantially at said light source and a second upper focus located substantially at an aspherical focus of a corresponding aspherical lens, said lower half portion having a rotated parabolic surface with a first lower focus located substantially at said light source.
