Abstract: An apparatus and method is characterized by providing an optical transfer function between a predetermined illuminated surface pattern, such as a street light pattern, and a predetermined energy distribution pattern of a light source, such as that from an LED. A lens is formed having a shape defined by the optical transfer function. The optical transfer function is derived by generating an energy distribution pattern using the predetermined energy distribution pattern of the light source. Then the projection of the energy distribution pattern onto the illuminated surface is generated. The projection is then compared to the predetermined illuminated surface pattern to determine if it acceptably matches. The process continues reiteratively until an acceptable match is achieved.

Abstract: In a system for controlling a headlight of a vehicle to be controlled, a dazzling level determiner determines a parameter value of a dazzling level of a driver of an other vehicle ahead of the controlled vehicle based on information associated with a relative positional relationship between the controlled vehicle and the other vehicle. The dazzling level represents a possibility that the driver of the other vehicle feels dazzling to light irradiated from the headlight of the controlled vehicle. A light-quantity adjuster adjusts a quantity of light to be irradiated from the headlight of the controlled vehicle based on the determined parameter value of the dazzling level.

Abstract: A reflector assembly includes a frame that maintains the integrity and shape of a multi-member reflector for a recessed luminaire. The members of the reflector are arranged in a geometric form, such as a rectangle. The frame is disposed around the reflector.
