Highly efficient, long living LEDs are really a disruptive technology in lighting. However, the vast variety of available components makes the optimal choice a challenge. In this presentation, we will discuss advantages and disadvantages of the different High & Mid Power LED packages, COB and Chip Scale Packages (CSP) for street lighting. Major criteria are efficiency, optics and glare, reliability/outdoor performance, flexibility/maintenance/service, total system cost. Since system’s performance obviously is crucially linked to optics and LED drivers as well, we provide an overview of the available categories of optics and considerations for LED drivers. We address the choice of light spectra, too (Efficiency vs. light pollution, circadian rhythm, glare – also in case of fog).
Besides maximum efficiency, total cost of ownership optimized components, perfect glare-free and well-shaped light patterns, there is much more a street lamp is offering: street lamps are being hooked up the IoT. Thus dimming levels can be set and controlled remotely either manually or by means of artificial intelligence in the cloud: Thus, smart street lights are being dimmed up during times of heavy traffic, but reduced if light pollution needs to be avoided. Big data analysis allows predictive maintenance and remote performance analysis in order to cut down costs.
But this is not the only added value of smart street lamps: they are an infrastructure hub with their power connection and the IoT connectivity and their prominent position is ideal for sensors. Thus we discuss the role of street lamps in smart cities with some example cases. All discussed solutions are available in EBV’s portfolio.
