1.1 Solar energy saving

At present, solar lamps are developing rapidly and begin to develop towards high power, and the lighting brightness can also meet the requirements. However, due to the poor wind resistance of solar panels, they are not suitable for wharfs with strong wind. However, medium pole lighting such as street lamps can be recommended, which has a lot of energy-saving space (see Figure 1).

1.2 The application of wind energy for wind power generation in lighting has been a very mature technology, and 1kW~10kW wind power lighting independent equipment has been formed and produced (see Figure 2). However, the blade is required to have a large rotating space, especially when the power is greater than 3 KW, the blade length is about 3 m, and the 180 ° range is an avoidance area. There are too many restrictions on wharf operation, and the one-time investment cost is high. Therefore, it is not recommended to use wind energy technology in the wharf yard lighting, but the same street lamps and other medium pole lighting can be recommended, which has certain energy-saving space.

1.3 Research on energy-saving lamps

According to the characteristics of high pole lamps at the wharf, great efforts have been invested in the research of energy-saving lamps. Four energy-saving lamps, namely CDM 150 (400 W), LED 80 (400 W), GEPF 400 and BSTG-135, have been selected for comparative testing of relevant parameters
