Energy saving has increasingly become the focus attention of all world because of the dual crisis of energy and environment. One of the most important sources of energy saving is saving energy on highways and express roads. Extensive research efforts have been made towards saving energy on highways and express roads. Although these efforts have researched a good level of energy saving by reducing energy loss during lighting, there is still an urgent need to save more energy to save money and also for environment protection. To the best of our knowledge, all the present energy saving technologies on highways and express roads depend on either using energy saving bulbs or using photocell street lighting. Also, using reflectors with two discharge lamps represents an energy and economic improvement of the street lighting with respect to traditional bi-power system. However, there is a need to develop more efficient energy saving techniques to save more money by reducing energy loss. Motivated by this, a new energy saving technique is proposed to reduce the energy loss on highways and express roads by efficiently using energy only when needed. |
