6.6. Architecture, facade, city marketing and visual presentationArchitecture is the application area where LEDs were firstly used with their advantages such as durability, easy control,low power consumption, and long lifetime. Nowadays LEDs are used almost everywhere. There are so many possibilitiesand their implementation depends on investor’s willingness to invest in such installation. LEDs create totally new appearanceof bridges, facades, and other architectural areas. Their great advantage for such applications lies in their size. LEDluminaires can be very small, resulting in ability to hide them in facades. In this case, they are virtually invisible, which isadvantage when luminaires are switched off.In the past, classic discharge lamps were used which led to limitation of usable color temperatures (CCT) – sodium dischargelamp (2000 K), metal-halide lamp (3000 or 4000 K). In order to create color light, we were forced to use colorfilters which decrease light output ratio and luminous flux resulting in higher amount of installed luminaires needed,higher energy consumption and higher installation and operation costs.With LED luminaire it is easy to set desired color of outgoing light resulting in freedom for designer’s ideas. Instant on,continuous control of luminous flux, addressing possibility and easy programming of lighting scenes allow for creatingdynamic lighting systems with time dependent change of light intensity, CCT and RGB colors.LED ACADEMYFigure 6.6.1:Design of LED illumination of manorhouse in Kittse.Figure 6.6.2:Examples of possible LED illumination ofmodern building and TV tower.37
