  • Patent number: 5634278
    Abstract: A bow sight includes a housing which is mounted on an archery bow and carries electronic circuitry including a series of aligned target LED's which may be programmed by an archer to correspond to different respective target distances. The housing mounts a color separating dichroic filter sight glass positioned at an angle between upper and lower housing walls. The LED's are positioned to overlay an elongated slot in the top wall so that a lighted LED reflects onto a surface of the glass and may be viewed for sighting a target. Two other LED's, one on each side of the target LED's, are included in the circuitry and may be programmed to light when the bow is tilted to a selected side-wise position, apertures in the top wall of the housing permitting reflection of each of these LED's onto the sight glass. After each target LED have been programmed, the archer may sight through the sight glass and align the reflection of the lighted target LED onto the target.
