On LED Luminous Efficacy and Energy Saving Technique in Lighting

Article Preview

Abstract:

With the fast upgrading of lighting facilities and living standard, the electricity consumption has been increasing rapidly in every nation in recent years. This study intended to use the luminous efficacy and energy saving technique in lighting as a scientific management method and an effective approach to enhance the industrial development, effectively uplift the efficiency in resource use, specify the work of energy saving management, elevate the management standard and boost economic benefits for industries. It is hoped to further create the safe, comfortable, health, economical and beneficial environment, while fully embodying the modern civilization of lighting technology.
