TH87994A - Light unit with reflector with adjustable rotation - Google Patents

Abstract

DC60 This invention relates to a parabolic reflector (1) which is placed inside a fluorescent light assembly behind each fluorescent lamp (3) and rotates at various positions around the imaginary axis of the fluorescent lamp (3) in fixed steps of 1 degree, 2 degrees or more, while being held firmly in place at all rotation positions. The parabolic reflector (1) of this invention is fixed in place and rotates in the side wall (5) of the light assembly housing (2) without needing to be supported on the fluorescent lamp (3) more specifically. The reflector (1) rotates in steps of 1 degree or 2 degrees or more and locks into place at each rotation position to avoid any movement in the event the reflector is accidentally pushed. This invention relates to a parabolic reflector (1) which is placed inside a light assembly. The parabolic reflector (1) of this invention is fixed in position and rotates in increments of 1°, 2° or more degrees around the imaginary axis of the fluorescent lamp (3), while being held firmly in all rotation positions. The parabolic reflector (1) of this invention is fixed in position and rotates in the side wall (5) of the lighting housing (2) without needing to be supported on the fluorescent lamp (3) more specifically. The reflector (1) rotates in increments of 1°, 2° or more degrees and locks into position at each rotation position to avoid any movement in the event the reflector is accidentally pushed.
