100w outdoor slim led floodlight can be divided into four types: rotational symmetry, two symmetrical planes, one symmetrical plane shape and asymmetrical shape according to the symmetry of the intensity distribution of the outgoing beam. Rotating symmetrical shape. The luminaire employs a rotationally symmetric reflector and mounts the axis of symmetry of the source with a rotationally symmetric light distribution along the axis of the reflector. The iso-intensity curves of such lamps are concentric. In this form of 100w outdoor slim led floodlight, the elliptical spot is obtained on the illuminated surface, and the illumination is uneven; however, when the multi-lamp is illuminated, the spots are superimposed on each other to produce a satisfactory illumination effect. For example, hundreds of rotary symmetrical 100w outdoor slim led floodlights are commonly used in stadiums, which are installed on high towers around the stadium to obtain high illumination and high uniformity. Two symmetrical plane shapes. The equal intensity curve of this type of 100w outdoor slim led floodlight has two planes of symmetry. Most of the luminaires use a symmetrical cylindrical reflector and the linear light source is mounted along the cylinder axis.
