LEDs for Energy Efficient Greenhouse Lighting
Light energy is an important factor for plant growth. In regions where the natural light source (solar radiation) is not sufficient for growth optimization, additional light sources are being used. Traditional light sources such as high pressure sodium lamps and other metal halide lamps are not very efficient and generate high radiant heat. Therefore, new sustainable solutions should be develop...
متن کاملTowards Highly Energy-Efficient Roadway Lighting
The reports presented by consulting firms show that annual energy costs generated by 340 million streetlights are expected to reach $23.9 to $42.5 billion by 2025. Those numbers reveal a motivation behind the research aiming at optimizing outdoor lighting energy efficiency. They show that even a small unit improvement can yield large benefits due to the effect of scale. The development of solid...
متن کاملEnergy-efficient control of solid-state lighting
Lighting control is in the midst of radical change. Presentday state-of-the-art lighting systems tend to be extremely complex. They exhibit very flexible actuation possibilities with many degrees of freedom that can be exploited to answer dynamiclighting needs. However, user interfaces to these systems are woefully lacking. They are frequently denigrated to a panel of buttons that select partic...
متن کاملEnergy - Efficient Lighting in China : Problems and Prospects
China’s choices of energy demand and supply technologies have a large impact on the world’s energy market and the environment. Of its 920 billion kWh electric power production in 1993, it is estimated that 15% was used for lighting consumption (~120 billion kWh). This figure is likely to grow as the country develops, and so improving the energy efficiency of lighting in China could have a treme...
