LEDThe shape of the spotlight can be divided into several categories
One of the classification of floodlights: rotational symmetry
The rotationally symmetric projection lamp is a rotationally symmetric reflector that is arranged along the axis of the reflector in accordance with the axis of symmetry of the source with rotationally symmetric light. A striking feature of this type of floodlight is that the equal intensity curve is concentric, and it is not suitable for single-lamp illumination. If the single-lamp illumination receives an elliptical spot on the illuminated surface; however, when the multi-lamp is illuminated, the spots are superimposed on each other, and a satisfactory cool illumination effect can occur. For example, hundreds of rotating symmetrical spotlights are commonly used in stadiums, and they are installed on high towers around the stadium to obtain high illumination and high uniformity.
Floodlight classification 2: two symmetry
The intensity curves of two symmetrical spotlights have two planes of symmetry. Most of the lamps use a symmetrical cylindrical reflector and the linear light source is arranged along the cylinder axis.
Floodlight classification three: a symmetry
A symmetrical projection light intensity curve is only required to have a plane of symmetry. The luminaire is selected from an asymmetrical cylindrical reflector or a symmetrical cylindrical reflector plus a light-limited grid. The most typical is the sharp cut-off block retracting light distribution. This type of light intensity spreads a single lamp to achieve a more satisfactory illumination spread.
Floodlight classification four: asymmetric shape
Light intensity curves such as asymmetrical light types have no symmetry plane. The main purpose is to use the mixed light fixtures of different kinds of light sources with different light intensity distribution and the special lamps designed according to the specific lighting requirements of the application place.
