In rural areas, lighting electrical ready boards play an important role in optimizing power consumption as key equipment for power distribution and control. Reasonably implementing "source opening and cost saving" measures can effectively improve the efficiency of rural electricity utilization and reduce energy waste.

In terms of "open source", intelligent lighting control systems can be introduced. Using solar panels to power low-power lighting equipment around electrical ready boards, incorporating clean energy into rural lighting systems, reducing dependence on traditional power grids, and achieving diversified energy supplementation.

The 'cost cutting' measures are equally crucial. On the one hand, regular inspections and maintenance should be carried out on the lines and equipment inside the electrical ready board, and aging and damaged wires and poorly connected circuit breakers should be replaced in a timely manner to reduce line losses and avoid power waste caused by equipment failures. On the other hand, it is necessary to plan the lighting layout reasonably and accurately configure the number and power of lighting fixtures according to the functional needs of different rural areas. For example, low-power LED lights are used in the courtyard of the farmhouse, and adjustable brightness lamps are installed in public activity areas to avoid excessive lighting.

At the same time, we will strengthen the promotion of electricity knowledge among rural residents, raise their awareness of energy conservation, and guide them to develop good habits of turning off lights and using electrical appliances reasonably. Through these comprehensive measures of opening up sources and reducing costs, optimizing the operation of rural lighting electrical ready boards can not only reduce electricity consumption and lower farmers' electricity costs, but also contribute to the sustainable development of rural areas, making rural nights both bright and energy-efficient.
