The original title of this article: The night of Niza Village is lit up--Tianjin Science and Technology Aid Project "Solar LED Street Light System Demonstration Project" officially completed "bright, bright". In the cheers of the villagers, the last streetlight in the “Solid LED Street Light System Demonstration Project†of Tianjin Science and Technology Assistance Project was installed and commissioned at the entrance of the village of Gongqiu Bading. Subsequently, the majority of the villagers in Niza Village gave the engineers who led them to fight for more than 20 days and sent the light to Tianjin to present the white Hada and the fragrant barley wine.
The "Solar LED Street Light System Demonstration Project" project assisted by the Tianjin Science and Technology Commission is specifically aimed at the characteristics of climate, sunshine conditions and soil temperature in the Tibetan Plateau region, in order to solve the practical problems of large power gaps and more power-hungry areas. The goal is to develop a new energy LED street light system suitable for use in highland areas.
The project undertaker Tianjin Gonghaiyu Semiconductor Lighting Co., Ltd. has developed a systematic key technology for high altitude climate after a large number of experimental experiments. Among them, ensuring the constant power output of the light source in the ambient temperature range of -30 °C-55 °C is an important research achievement of the company to solve the system instability problem in harsh environment. In addition, the ultra-high system charging efficiency is nearly 20% higher than that of the general solar street lamp system; the solar module of the system configuration is a military-grade reliable quality single crystal silicon material, the photoelectric conversion efficiency exceeds 19%; the energy storage system uses high-efficiency colloid The energy storage battery pack has a battery capacity of over 80% at -10 °C.
In terms of system integration, the light source of optical structure developed by Gonghaiyu Company itself is used. The 35W LED lamp emits light equivalent to other 45-watt LED lamps that have been applied in Changdu area, and is a truly high-efficiency energy-saving light source. The five key components of the system work closely with the local conditions, ensuring that the solar LED streetlight system for this application can operate without problems for more than 3 years under the premise of 13 hours of lighting per day, and guarantees that even continuous rain and rain for 5 days Can work normally.
After the completion of the project, the technicians of Gonghaiyu cooperated with the local cadres to conduct on-site lighting effects tests and found that the area of ​​the illuminance line of 10 lux reached 260 square meters, and the ground area had a light area of ​​more than 800 square meters.
In addition to product development, street lighting design and engineering construction are two other problems encountered in project implementation. “Technology and Huimin†is the implementation guideline and important goal of the Tibet Aid Project. In order to effectively enable local farmers and herdsmen to obtain the benefits brought by science and technology, the Tianjin Science and Technology Commission, Gonghaiyu and Changdu District Science and Technology Bureau exchanged opinions and decided to The construction site was changed from Changdu District to Niza Administrative Village in Wuqi County.
The problems of scattered households, habits based on animal husbandry, complex terrain, and the inability to settle large construction equipment have brought difficulties to the implementation of the project. In terms of lighting design, in line with the priority of the intersection, taking into account the labor space such as the farmyard and the cowshed, the lamp point layout is on the side of the road and the principle of internal points is used to examine the lamp position, and strive to meet the actual needs and guarantees of local farmers and herdsmen. Maximize the utilization of lighting under the premise of beautiful layout.
During the construction period, Tianjin engineers continued their altitude sickness and worked with the villagers of Niza to overcome various difficulties such as rainy days, slippery mountain roads, strong sunshine radiation and scattered construction sites, which ensured the successful completion of the project. After the completion of the project, the two natural villages under the Niza administrative village realized full coverage of solar LED street lights. A total of 108 households and 515 local people received benefits. At the same time, under the guidance of Tianjin engineers, many local villagers accepted the LED street lighting system. The training of installation and commissioning, with the words of Tianjin engineers: "After our detailed explanation, demonstration and guidance, the villagers of Niza can solve most of the system maintenance problems themselves, and there will be similar projects in the future. Niza Village pulled up an engineering team directly."
The solar street light has effectively realized the road to the township road, and the warm-hearted households in the hospital are bright. The lighting demonstration project brought a bright light, and Tianjin’s aided construction day and night told the Han and Tibetan family. The application of scientific and technological achievements not only brings benefits to Niza Village, but also brings many popular knowledge and engineering knowledge to farmers and herdsmen in Tibetan areas. The Tibetan spirit, which is not afraid of hardships and works in unity, has been fully embodied and promoted through the implementation of the solar street lamp demonstration project.
