Abstract: In order to strengthen the city's night lighting management, beautify the city's night scene, display the new image of the city with historical and cultural features and modernization, and promote economic development. In accordance with relevant regulations, combined with the actual situation of the city, these measures are formulated. The first one is to strengthen the city night lighting management, beautify the city night scene, display the new image of the city with historical and cultural features and modernization, promote economic development, and formulate these measures in accordance with relevant regulations and the actual conditions of the city. Article 2 The following buildings (structures) or places within the administrative areas of Xincheng District, Beilin District, Lianhu District, Yanta District, Weiyang District and Yongqiao District (hereinafter referred to as the District) of this Municipality shall be set in accordance with the provisions of these Measures. Urban night lighting facilities: (1) Buildings (structures) on both sides of the main street of the city; (2) Urban bridges and cultural relics; (3) Urban landmark buildings (structures); (4) Main streets Street signs, commercial thresholds; (5) other facilities that require lighting. The scope of the main street of the city is determined by the municipal administrative department. Article 3 The term “city night lighting†as used in these Measures refers to the lighting and beautification of urban night scenery by using lighting facilities and technology. Article 4 The night illumination of the city shall follow the principles of unified planning, scientific setting, outstanding features, and harmony and beauty. Article 5 The municipal administrative department of administration is the competent department of the city's urban night lighting work. The district people's government is specifically responsible for the organization, implementation and management of urban night lighting in its administrative area. The High-tech Industrial Development Zone, Economic and Technological Development Zone, and Qujiang New District Management Committee are specifically responsible for the organization and implementation of night lighting in the area. Article 6 The departments of planning, construction, cultural relics, gardens, public security, civil affairs, and electric power shall, in accordance with their respective duties, cooperate with the city's night lighting and management. Article 7 The urban night lighting construction plan shall be incorporated into the overall urban planning. The urban night lighting planning shall be prepared by the municipal planning administrative department in conjunction with the municipal administrative department. After being evaluated by the expert committee and reported to the municipal people's government for approval, the municipal administrative department shall organize the implementation. The urban night lighting zoning plan is prepared by the district people's government and the development zone management committee according to the city's night lighting plan, and reported to the municipal municipal administrative department for the record. In the zoning plan, the main avenues should adhere to the principle of unification of prosperity and characteristics; for the night lighting planning of each building (structure), it is necessary to adhere to the principle of not only highlighting the architectural style but also coordinating with the environment. Article 8 The night lighting facilities of newly built or rebuilt buildings (structures) or urban squares must be designed, constructed and put into use at the same time as the main project. Article 9 The night lighting facilities of the city shall be funded by the owners or management units of the building (structure) and shall be responsible for the daily maintenance and management of the facilities, and maintain the integrity, function and appearance of the urban night lighting facilities.

In the rectifier circuit; the use of diodes in series can increase the back pressure withstand value (usually the sum of the back pressure of all diodes, but it is best to use diodes of the same specification).
In the voltage stabilization circuit; the series connection of the diode is equal to the sum of the voltage stabilization value of the diode. The use of diodes in parallel is theoretically the sum of rated currents, but considering that it is impossible to be absolutely symmetrical, they can only be used below 80% of the total.
TVS transient suppressor diodes work in the same way as regulator diodes, but there are structural differences.The biggest difference is that the PN junction area composed of the general regulator diode is very small, it can withstand the reverse current is small.
