Adjustable illumination apparatus having pre-focused led and magnification lens
First Claim
1. A portable lighting apparatus, comprising:
- (a) a base;
(b) an adjustable arm extending from said base; and
(c) an illuminated optical assembly connected to said adjustable arm, said illuminated optical assembly comprising;
(i) a magnifying lens having a defined focal point;
(ii) a plurality of LED'"'"'s disposed around said magnifying lens, said LED'"'"'s angled to provide optimum lighting at a focal point of said magnifying lens, whereby a central axis of the light beam radiated from each said LED approach each other, but said central axis do not intersect at or before the focal point of said magnifying lens, (iii) a mounting, ring disposed around the periphery of said magnifying lens, said mounting ring including a lower surface and an upper surface, wherein said lower surface being directed generally toward the focal point of said magnifying lens, (d) a lens hood being provided, said lens hood having an annular channel and a centrally defined opening therein, wherein said annular channel being, adapted to receive said mounting ring and said opening being adapted to receive said magnifying lens.

Abstract
An illumination apparatus that has a magnification means in combination with LED'"'"'s (Light Emitting Diodes). The LED'"'"'s are arranged in an array inside a lens hood that surrounds the magnification means and are mounted at an angle to provide optimum lighting onto the focal point of the magnification means. The lens hood is fixed to an adjustable arm that is attached to a base. The adjustable arm allows the magnification means and LED'"'"'s to be directed at virtually any angle onto a workpiece. The base allows the apparatus to be self-standing and is adapted to receive a portable power source for powering the LED'"'"'s. The apparatus may incorporate a diffuser lens to provide a softer lighting effect.
