The problems caused by light pollution are getting worse, but all relevant government departments are saying that they are not within the scope of their ownership. The reporter finally found the most likely related Shenzhen Habitat Committee, issued a written interview outline and repeatedly urged it. The reply is: "The 10 business offices are unable to respond to the problem of light pollution. At present, there are no relevant laws and regulations on the issue of light pollution, and there is no clear authority department. Therefore, it is not under our control. It is recommended to go to the urban management bureau or build. Competent authority."
There is still no solution. On the issue of light pollution, we can only initiate discussions and suggestions from relevant professionals, and see if other cities or countries can learn from experience.
There is no legislation on light pollution in Hong Kong
In Hong Kong, which is close to Shenzhen, the density of the city is higher, the business and the house are more integrated, and the internationalization of the city itself is higher. The problem of light pollution such as glass curtain wall, LED and neon is even worse than that of Shenzhen. Light pollution in Hong Kong involves a number of departments, including the EPD, the Housing Department, the Fire Services Department, the Marine Department, the Police Force, the Civil Aviation Department and the Food and Environmental Hygiene Department. Among them, only the data released by the Environmental Protection Agency showed that in the four years from 2005 to 2008, 190 complaints about lighting problems were received, and there is a trend of increasing year by year.
Even if the problem of light pollution is serious, Hong Kong has not yet enacted legislation. Once a lawsuit is filed, it is generally filed as an “infringementâ€.
Open the official website of the Hong Kong Environmental Protection Agency. Its special laws have covered air pollution, waste disposal, water pollution, noise control, ozone layer, dumping materials at sea, toxic chemicals, etc. Even the parking stalls have been introduced quite specifically. Terms, but light pollution is not among them. Nandu reporter interviewed Shi Ruolong, senior partner of Dacheng Law Firm and executive director of Hong Kong. He also said that light pollution is also an emerging issue in Hong Kong. Although the Legislative Council has discussed it, many bills are currently being lined up to receive information. In view of this, there is currently no special legislation on light pollution in Hong Kong.
How do the people of Hong Kong respond to the inconvenience caused by light pollution? The reporter learned that for the light pollution disputes that have arisen in the private sector, it is generally not for the people to sue. "For example, some traditions will burn incense and smog outside the door during the first day and the fifteenth. The neighbors will of course be affected, but if the neighbors do not file a lawsuit, the government will not interfere, but if the neighbors think of themselves If the rights are violated, they can complain to the management office. According to the previous deed of mutual covenant on the public space, they can also file a lawsuit.†Shi Ruolong said that this metaphor may not be appropriate, but the Hong Kong law has a basic attitude towards both. It is similar. The government will actively improve the light pollution generated by the municipal facilities, such as the installation of cut-off lamps or visors.
Japan: Advertising lighting cannot use laser
Hong Kong has also prepared to draw on the regulations of other cities in dealing with light pollution. In the document published by the Hong Kong Legislative Council, a document numbered IN 08/08-09 summarizes the light pollution in Japan, the United Kingdom and the United States. Legislative situation.
In terms of mandatory enforcement, there are mandatory regulations in the United Kingdom and California, and government approval is required before lighting installations or buildings are opened. The various regulations issued in Japan are basically in the scope of guidance, and no government approval is required. There is no subsequent enforcement.
In terms of management methods, Japan and the United States have classified lighting areas for lighting areas. Among them, California has included wildlife protection areas as the first-level lighting area, requiring the lowest energy consumption lighting facilities, and Japan. The natural parks and residential communities that should be intrinsically dark are positioned as the first-level lighting area, and the control is also the most stringent, requiring the lighting device to have the lowest brightness. However, the restrictions adopted by the two are different. Japan uses brightness to correspond to different levels, while the United States corresponds to energy consumption.
In terms of details, Japan requires that the advertising lighting can not use searchlights or laser beams. When the UK requires the use of floodlights, it should ensure that the local facilities are not affected by excessive lighting. California has set the upper limit of the lighting power of the lighting facilities to 175 watts. Use a "shading" design to let light hit the ground.
Hong Kong: In 2008, some glazing panels were installed on wall-mounted street lamps.
On January 7, 2009, Mr. Ye Kwok-him raised a question on light pollution. He said that some environmental protection organizations found that some of the wall-mounted street lamps installed on the external walls of the building were seriously affected by the sleeping quality of the residents due to their close proximity to the residents' windows. In the inquiry, Ye Guoqian also mentioned the problem of melatonin secretion caused by too strong light.
The Secretary for Transport and Housing said that since 1980, the Highways Department has avoided installing street lights on the external walls of buildings to reduce the impact on residents. If the location is close to the residents' windows, "light-cut" lamps will be used where circumstances permit. Improve lighting and energy saving, and avoid light source scattering caused by lamp leakage, reducing nuisance to residents. The Highways Department will also install visors depending on location and actual needs to prevent light sources from scattering to the exterior walls of the building. The reply also stated that in response to public appeals, the Highways Department completed a preliminary review of wall-mounted streetlights outside all residential buildings in Hong Kong in December 2008. In addition to the installation of cut-off lamps or visors, the street lamps will be adjusted on the external walls. Position, or change the wall light to a column light.
Another member, Li Yongda, continued to ask questions about the light pollution of large billboards and proposed to legislate to manage related issues. The Secretary for the Environment has responded that the Electrical and Mechanical Services Department has also discussed the above issues with the Chamber of Commerce to encourage them to reduce the luminosity of their billboards as far as possible without affecting them. Mr. Liu Xiucheng suggested that the commercial district and the residential area should be treated separately, but the Secretary for the Environment responded that “the residential and commercial districts of Hong Kong are often just across the street†and the difference will be more difficult. However, it is suggested that some forms of supervision can be formulated with energy waste as the main line.
