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 کاملLEDs Lighting Arrangements for Underground Mines
Lighting condition is very critical to mine workers, since they completely depend upon visual indication. Effective lighting systems provide better visibility and contribute to improved safety, production, productivity and efficiency of equipments. This paper intended to present a simulation study of configurations for the uniform illumination over a rectangular-target surface (underground mine...
متن کاملPico Power – Lighting Lives with Leds
In the past 5 years, high brightness LEDs have begun to penetrate the lighting market. High brightness LEDs are attractive due to their high efficiency, very low power consumption and very long lifespans. This paper describes experiences in using white LEDs for lighting rural households in developing countries. The Light Up The World Foundation (LUTW) is an aid organization that has formed part...
متن کاملRefrigerated display case lighting with LEDs
The rapid development of high brightness light emitting diodes (LEDs) has triggered many applications, especially in the area of display lighting. This paper focuses on the application of white LEDs in refrigerated display cases. The fluorescent lighting presently used in commercial refrigerators is inefficient in the application and also it provides poor lighting for merchandising. A laborator...
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...
