An ordinary worker, from the beginning of repairing the navigation light, broke through the two difficulties of improving the navigation light and developing the navigation mark, entered the kingdom of developing the navigation light, and completed 17 technological innovations, of which 2 were national patents and 4 were national. The Excellence Award and 5 awards were awarded by the former Ministry of Communications. He invented the integrated navigation light, which integrates light source, light source circuit and Solar Panel. It has the advantages of energy saving, environmental protection and maintenance-free. It is called a revolution in the history of navigation light. He is known as the "communist of the navigation lights" outstanding Communist Party member Zheng Qixiang.
Back in May 2006, the 16th International Navigation Lights Association Conference, which gathered hundreds of beacons and experts from 44 countries and regions, was held in Shanghai. As the representative of the Yangtze River Waterway Bureau, Zheng Qixiang took the “HD100 Solar Integrated Navigation Light†developed by him at the meeting, which aroused the strong interest of the delegates. The integrated navigation light integrates the light source, the light source circuit and the solar panel. It has the characteristics of energy saving, environmental protection and maintenance-free. The delegates praised the integrated navigation light as a revolution in the history of the navigation light. Zheng Qixiang was also known as the Yangtze River navigation light king.
Zheng Qixiang has only read the elementary school, but he has developed the most advanced navigation light on the Yangtze River. People can't help but ask how successful he is? Zheng Qixiang was an electrical fan since he was a child. After he was transferred from the army to the instrument repair team at the Honghu Channel of the Yangtze River Waterway Bureau, he taught himself the junior high school and high school culture courses, self-repaired e-learning classes, and devoted himself to the improvement and development of the navigation lights. In the past 25 years, I have been striving for it.
The navigation light consists of a light source, a circuit, a Battery, and a casing. From the 1970s to the end of the 1980s, almost all of the navigation lights on the Yangtze River channel used incandescent bulbs and neon tubes. These two kinds of light sources are easy to damage, difficult to repair, short in life, high in power consumption, and the damage rate is 45%. Zheng Qixiang from his many years of repair experience, in response to the above-mentioned defects, after comparative analysis, the use of light-emitting diodes to form a new light source, the luminous effect is very good, so he decided to use 8 light-emitting diodes to form a plum-like light source. The test results show that the new light source will increase the line of sight and luminous brightness of the beacon light from 2.5 km to 5 km. After more than a year of trials, he found that the lamp also has problems such as rusting and breaking of metal pins, easy water ingress, and poor contact of the lamp holder. To this end, Zheng Qixiang has used his brains to learn and absorb advanced technologies such as LEDs at home and abroad, and decided to inject the LED core into a whole and form an integrated new beacon light source. The advent of this light source completely replaced the original incandescent lamp and neon light source, and the brightness increased by 2 times, and the power consumption was only one third. The new beacon light can save 60% of the cost. This research achievement won the Outstanding Award of the former Ministry of Communications in 2003 and the national patent in November 2004. A senior expert from the former Ministry of Communications said in the assessment of this achievement: "The new navigation light source has epoch-making significance 1
