摘要: The present disclosure is an improvement in bi-focus lenses. The disclosure relates to the use of multiple channels of LED/Lens combinations to achieve a smooth and continuous range of emitted beam angles of light in a wider range of beam angles than previously possible through only two channels of LED/Lens combinations. The resultant product will produce a continuous range of beam angles in a range exceeding 35 degrees from narrowest bean angle to widest beam angle. The lens channels selected are weighted so as to maximize the contribution of a single channel lens to the overall beam projection.
