Bow sight with controlled light intensity sight pin
View Patent ↗An improved sighting device is provided. The sight may be used on a bow or other device which is typically sighted on an object during use. The sight includes at least one light-gathering fiber-optic fiber having at least one end from which absorbed light may be transmitted for viewing by a user. The fiber-optic fiber includes an associated element that regulates the amount of light absorbed in inverse proportion to the impinging light intensity in an automatic manner providing a more constant light intensity output.
1. A bow sight including:
a frame;
at least one sight pin mounted on the frame;
at least one light-transmissive fiber associated with a respective said pin; and
a light-sensitive element associated with at least one said fiber and operable to regulate an amount of light being transmitted from the fiber in response to a change in incident light on the light-sensitive element which darkens with increasing light intensity.
2. A bow sight as set forth in claim 1 wherein the light-sensitive element being operable to reduce the percent of light absorption in response to an increase in at least one component of the incident light.
3. A sight device for use with a shooting device including:
a mount adapted for securement to a shooting device;
a light-transmissive fiber secured to said mount; and
a light-sensitive element associated with said fiber and operable to regulate an amount of light being transmitted from the fiber in response to a change in incident light on the light-sensitive element which darkens with increasing light intensity.
4. A sight device as set forth in claim 3 wherein the light-sensitive element includes a photochromic material.
5. A sight device as set forth in claim 4 wherein the light-sensitive element includes a light-transmissive housing covering at least a portion of the fiber.
