Study of healthy light-color parameters for LED lighting

Twelve kinds of luminous environments were set up with white LED light source by changing the color temperature and illumination. Using feel discriminative index and the reaction time as the evaluation index, the effects of different luminous environments on human psychological feelings were researched, based on Signal Detection Theory and open windows. The results showed that lighting environm...

Dimming LED Lighting

LED lighting has the potential to offer many benefits to the user and to society as a whole. Very high efficiency together with extremely long life expectancy of the LEDs reduces the energy consumption and the use of resources, and can offer low lifecycle cost. In order to become widely accepted, LED lighting must provide dimming capability at least equivalent to that offered by traditional inc...

New Framework of Sustainable Indicators for Outdoor LED (Light Emitting Diodes) Lighting and SSL (Solid State Lighting)

Light emitting diodes (LEDs) and SSL (solid state lighting) are relatively new light sources, but are already widely applied for outdoor lighting. Despite this, there is little available information allowing planners and designers to evaluate and weigh different sustainability aspects of LED/SSL lighting when making decisions. Based on a literature review, this paper proposes a framework of sus...
