Light distribution curve of the common two kinds of representation
Methods a polar representation
define this method is often used to describe the lamps and lanterns of indoor and road light distribution. It is vividly expressed in polar coordinates of the origin of lamps and lanterns light center, to a certain direction vector of the size of the light intensity, expressed as a polar Angle intensity vector and the Angle between the optical axis;
the advantage of the features of polar representation is image, intuitive
method 2 rectangular coordinate representation
define this method is usually used to describe the lamps and lanterns of omni and light distribution is very narrow and the distribution of the light source of light. With rectangular coordinate origin said light center, with horizontal direction Angle, expressed in the vertical light intensity.
specific rectangular coordinate representation is easy to check different point of view of the benefits of intensity values
