1. A lighted archery nock assembly adapted to be joined with an arrow shot from an archery bow, the lighted nock assembly comprising:
- an arrow nock defining a groove adapted to engage a bowstring;
a battery including a pair of electrical terminals for providing electrical power;
circuitry electrically coupled to said pair of electrical terminals of said battery and joined with said arrow nock, said circuitry including;
an accelerometer that generates an accelerometer output indicative of acceleration of said lighted archery nock assembly;
a light source visible through at least a portion of said arrow nock; and
a controller electrically coupled with said accelerometer and selectively electrically coupled with said light source;
wherein said controller pulse width modulates illumination of said light source as a function of said accelerometer output to conserve battery life by selectively completing a circuit between said battery and said light source;
wherein said pulse width modulation is triggered in response to said accelerometer output indicative of acceleration of said lighted nock assembly exceeding a pre-set threshold acceleration; and
wherein said pre-set threshold acceleration is established as a function of G forces that accompany shooting the arrow from the archery bow.

Abstract
The present invention generally relates to a lighted archery nock. The lighted archery nock generally includes an accelerometer, a replaceable battery, a light, a housing, and a controller that controls illumination of the light. The controller can control emission of the light to conserve battery life, and can respond to user input transmitted by tapping the nock to re-set the light. The housing is configured with a plurality of fingers that secure the replaceable battery.
