A lighting fixture includes a light unit, a supporting frame pivotally coupling with the light unit, and an angle adjustment arrangement including a first gear member provided at the light housing, and a second gear member provided at the supporting arm. The first gear member has a first teething face to match and engage with a second teething face of the gear member. When the first gear member is moved apart from the second gear member, the light housing is adapted to pivotally move with respect to the supporting frame so as to selectively adjust the projecting angle of the light unit. After the projecting angle of the light unit is set, the first gear member is moved back to re-engage with the second gear member to lock up the light unit at the projecting angle.
