LED flood lights, mainly used for architectural lighting purposes, as well as commercial space lighting, decorative element heavier, its appearance is also a well-rounded, as generally have to consider the heat sink, the shape are quite different with the traditional flood lights. LED Floodlight according to their output beam intensity distribution into rotational symmetry symmetrical, two symmetrical planar, a planar symmetrical and asymmetrical shape four kinds.
1 rotationally symmetric shape. LED floodlight reflector using rotational symmetry and rotational symmetry of the source light distribution along the symmetry axis of the reflector axis installation. Such lamps isocandela curve concentric circles. This form of cast light lamp in the single lamp lighting, affected by the oval-shaped illuminantion uneven; but in the multi-lamp lightings, they superimposed on each other, you can produce satisfactory lighting effects. If the stadium on hundreds of commonly used rotationally symmetric shape Spotlights installed in the stadium around the tower to get high illumination, high uniformity of lighting effects.
2 two symmetrical planar shape. Such Flood Light curve has two symmetry planes. Lumination mostly uses symmetrical cylindrical reflector, and will the straight-line like light source along the cylindrical surface axis of the installation.
3 a symmetry plane shape. Lamps curve is only one plane of symmetry. Lamps using the cylindrical reflector asymmetrical or symmetrical cylindrical reflector grid sheet plus limited light. The most typical is the sharp cut-off block retraction shaped light distribution. Such single light intensity distribution can be obtained more satisfactory illumination distribution.
4 asymmetric shape. Such lamp curve has no symmetry plane. Main difference is the use of a larger light intensity distribution of the light mixing different types of light fixtures and the use of premises under specific lighting requirements and design of special lamps.
