The City

The city of Los Angeles is converting its streetlights from orange-gold sodium vapor technology to cold, white light-emitting diodes. It’s a transition that will change the color of the city at night, in a place with a long history of experimentation with artificial lighting technology. That means not only that the city will appear different, but it will no longer correspond to memories of its coloration, or to its depictions in famous films.

Flat Beam

The article presents one of the possible options for implementing the lighting technology "Flat beam" for landscape lighting purposes. One of the possible ways to control the light distribution of a number of light sources based on LEDs with different radiation patterns is considered. As a secondary optics, it is proposed to use a mirror surface that redistributes the light flux of an LED light source. It is indicated that, depending on the initial type of the light-emitting diodes light curve and the features of mounting the mirror surface, the resulting light distribution can vary widely, depending on the initial task that the designer sets for himself.
