Patent ID: 8066411

Claim:
An LED lighting tube comprising: (a) a first segment and a second segment, each segment having: (i) an elongated, hollow, cylindrical housing, the cylindrical housing being aluminum, the cylindrical housing having a diameter of approximately ⅝ inch and having a sidewall; (ii) an elliptical aperture in the sidewall of the cylindrical housing; (iii) a parabolic reflector centered within the elliptical aperture; (iv) a circuit board within the cylindrical housing, the circuit board having a light emitting diode (LED), the LED aligning with the elliptical aperture and the parabolic reflector such that light emitted from the LED shines out of the elliptical aperture; (v) a rotatable electrical coupling connected to an outer end of the cylindrical housing, the rotatable electrical coupling comprising (1) a limiter insert providing a rotative stop, (2) a graduated collet, the graduated collet at least partially surrounding the limiter insert, the graduated collet having indications along a peripheral edge, the graduated collet being rotatable about the limiter insert, the rotation of the graduated collet about the limiter insert being limited by the rotative stop to not exceed about 190 degrees, the indications signifying an angle of rotation of the graduated collet in relation to the limiter insert, (3) locking means for locking the rotation of the graduated collet about the limiter insert at a desired position, the locking means comprising a set screw, (4) a two-prong connector secured to the limiter insert by way of a threaded collar connector, the two-prong connector being in electrical communication with the circuit board, and (5) an end plug inserted into the graduated collet, the end plug supporting the two prongs of the two-prong connector; (vi) a colored lens to alter the light emitted from the LED; (vii) a groove proximate the elliptical aperture, the groove shaped and dimensioned to accept the colored lens, the colored lens substantially covering the elliptical aperture; and (viii) a semi-cylindrical frame connected to the circuit board, the frame shaped and dimensioned to allow the frame and the circuit board to be slidably inserted into the cylindrical housing; and (b) a rotating connector between the first segment and the second segment of the LED lighting tube, the rotating connector rotatively and electrically connecting an inner end of the first segment and an inner end of the second segment.
