Shenzhen publicized LED lighting to create an intelligent management platform within two years in Shenzhen

The Shenzhen Municipal Government recently issued the "Implementation Plan for the Promotion and Application of LED Lighting Products in Shenzhen" to fully promote the delisting of incandescent lamps, and said that "the problems encountered in the implementation, please reflect to the Municipal Science and Technology Innovation Committee."

Main road lights such as the North Ring need to be reconstructed
The "Notice on the gradual prohibition on the sale of ordinary lighting incandescent lamps" jointly issued by the National Development and Reform Commission, the Ministry of Commerce, the General Administration of Customs, the State Administration for Industry and Commerce and the General Administration of Quality Supervision, Inspection and Quarantine, stipulates that sales and imports of 100 watts and above will be banned from October 1 this year. Incandescent lamps for general lighting. The Shenzhen Municipal Government implemented the program on the 9th of the 20th, and proposed the goal of popularizing LED lighting in the field of public lighting for two years.

The "Proposal" requires that the first step in the field of public lighting, that is, urban roads, public places, government agencies, state-owned enterprises and other financial or state-owned capital investment in the construction of lighting engineering, the implementation of LED lighting products.

From the date of implementation of the scheme, all new lighting projects in the above fields will adopt LED street lights, garden lights and landscape lights, etc.; the original non-LED lighting products will be used for two years, that is, by the end of 2013, in batches and batches. carry out.

Starting this month, the district governments (new district management committees) and relevant municipal departments will determine the energy conservation service companies and supervision agencies through bidding and sign relevant contracts. From next month, the energy service company will carry out engineering design, LED lighting procurement and installation, and tracking services in accordance with the contract progress. At the end of the year, relevant departments will start engineering inspection and supervision work.

The "Proposal" requires that each owner unit adopts a public bidding method to select an energy-saving service company and specifically undertake the implementation of the LED lighting project in the public lighting field.

Aviation headphones are used in airplanes, cars, subways, etc., to facilitate passengers to listen to audio and watch videos to enjoy a pleasant journey.

The aviation earphones are mostly disposable, so the structure is extremely simple, the shape is relatively ordinary, the materials are small, and the annual usage is very large. The number of inquiry can reach several million or even tens of millions, so the cost is very cheap. earphones can cost as little as 10-15 cents. Therefore, they are disposed of as garbage after used, and passengers could take it away for personal use.

Styles can be divided into on ear headphones and in ear earphones.

Functional difference: power, impedance, and sensitivity etc. are also different. Airplane Headphone is mainly customized according to the equipment, place and user used. For example, 1 customer might  require 300 ohms impedances , and other customers may need 32 ohms. For adults, the sensitivity may reach 100DB or more.To children, the sensitivity may be around 85-90 DB.

In addition, aviation headphones are not all disposable ones. Some first-class cabins need to be equipped with headphones with good noise reduction, sound quality and functions. So the price will be much more expensive.
