According to the symmetry of the light intensity distribution of the outgoing beam, the projection lamp can be divided into four types: rotational symmetry, two symmetrical plane shapes, a symmetrical plane shape and an asymmetrical shape. ① Rotational symmetry. The luminaire employs a rotationally symmetric reflector, and the axis of symmetry of the light source with a rotationally symmetric light distribution is mounted along the reflector axis. The isointensity curves of such lamps are concentric circles (Figure 1). When this type of floodlight is illuminated by a single lamp, an elliptical spot is obtained on the illuminated surface, and the illuminance is uneven; but when multiple lamps are illuminated, the spots are superimposed on each other, which can produce satisfactory lighting effects. For example, hundreds of rotationally symmetrical projection lights are commonly used in stadiums, which are installed in
