摘要：Many lighting energy-saving modification programs have the embarrassment of uneconomical. This paper takes into account economic evaluation to solve the problem. According to illuminative equipments price, life span and power consumption, the optimal program will be found under the limited investment. Firstly, the benefit ratio will be used to evaluate on the equipments modification necessity, and get the modification sequence. If the biggest benefit ratio is in different equipment simultaneously, the better one will be selected in terms of relative investment recovery period. The relative remaining time is innovatively introduced into economic evaluation for determining the equipments modification locations. Then the system operation flowchart is to prove that the scheme is workable.
