System of reflectors and base of parabolic fluorescent luminary for concentrating and guiding light, with improved light output and reduction in construction cost. On the support base of the electrical components of the luminary, two of the four side walls are made of plastic, which are assembled by easy and quick snapping to the main body of iron sheet. These plastic side walls have specific cavities and projections for mounting a grid of parabolic reflectors, which consists of the following, two separate parts made of thin plastic film of at least one reflecting surface: (i) the main parabolic components for directing the light, which are placed under fluorescent lamps, and (ii) the upper cross-made grid, which can be removed from the luminary independently of the main parabolic components. Thus, the main parabolic components do not need to have openings along the lamps. As a result, their continuous parabolic shape improves significantly the light output of the parabolic luminary. |
