Questions about the installation of LED street lights by EMC 20

As far as I know, the energy subsidy of LED street lights is given to the energy user, but you can reach an agreement with the energy user, how much energy you can save for him, and how much percentage of it will be given to you, so that you can not only help others, but also benefit yourself.

There is no requirement for the length of lighting time, and the local ** directly subsidizes the energy-consuming units.

LED street light installation method:

1) The installation height (from the light source to the ground), elevation angle, and lighting direction of the street lamp at the same location should be consistent.

2) The longitudinal centerline of the lamp installation and the longitudinal centerline of the lamp arm should be consistent, the horizontal line of the lamp should be parallel to the ground, and there should be no skew after fastening.

3) The lamp head is fixed firmly, the adjustable lamp head should be adjusted to the correct position according to the design, and the wiring of the lamp head should meet the regulations.

4) All kinds of nuts should be fastened, and gaskets and spring pads should be added.

After the LED street lamp is installed, it needs further debugging to ensure its normal use.

Street lights have high power and big interference, like 3W and 5W bulbs, which don't pay much attention to EMC at all.

The ground floor is pure.

Shopping malls are not popular projects, not political performance projects, can not be established separately without the lead and strong promotion of the first, in the country can not do in addition, the country also has to promote LED projects from a strategic point of view, and shopping malls often from the perspective of businessmen.

Generally, it takes tens of millions of big projects to do EMC, and who will do this for ordinary small projects.

Through the investment and implementation of energy efficiency, energy saving and carbon reduction technology solutions for urban public lighting terminals and contract energy management services, the goal of energy saving of 40%-65% will be achieved on the energy consumption benchmark of terminal equipment before the transformation, and the energy-saving results of recognized projects will be achieved through the emission rights verification mechanism, and the carbon reduction demonstration project of urban road lighting will be built.

The energy saving and emission reduction of this project, relative to the confirmed baseline, has authenticity and uniqueness, is measurable, verifiable and reportable, to ensure that the best party can obtain the national emission reduction results of the project certification, and gradually establish a public building power saving carbon reduction demonstration area, urban comprehensive carbon reduction demonstration area. The project adopts the following technical equipment and measures to achieve the purpose of energy saving:

Replace the inductive ballasts of the current street lamps with intelligent ballasts that have passed the national energy-saving certification;

The Longfuhua light source that meets the national energy efficiency evaluation standards is used to replace the high-pressure sodium light source of the current street lamp;

Some of the equipment uses high-efficiency street lamps and lanterns to replace the existing old street lamps and lanterns;

Energy efficiency management chips are used in street lamps to improve the power quality of street lamp terminals;

Transform some street lamps that are not designed to meet the standards to meet the current national road lighting standards; The intelligent chip is used to implement the fine management of street lighting. 1. After the energy-saving service company carries out energy-saving transformation, the electricity fee paid by the power department in the current month will be deducted according to the electricity fee set by both parties, and the remaining will be the power-saving income of the project, which will be shared by both parties and the energy-saving service company.

2. The energy-saving service company shall bear its own risk for the energy-saving technology adopted, in addition to ensuring the lighting rate of the street lamp, if the energy-saving rate of the project does not reach the expected income, it shall be responsible for its own profits and losses, and shall not put forward other income requirements for the first time. 1. The energy-saving service company helps to improve the quality of public lighting facilities, and renews all the old and bad street lamps in the existing road lighting;

2. The energy-saving service company shall carry out free monitoring, maintenance and technical upgrading of the project during the contract period.

3. Provide full funding and project implementation assistance to establish a project identification system;

4. Provide full funding and project implementation to help establish an energy-saving monitoring center and a panoramic demonstration system for the city.

It is recommended to refer to the international standard CISPR15 or EN55015 The corresponding national standard is GB17743, but the update of the national standard is relatively slow, depending on whether you are exporting or domestically selling, the test method is partially different from the requirements, but it is generally the same.

LED lamps need to be tested by EMC as follows: harmonics, flicker, conduction, radiation, electrostatics, pulse group, surge, power frequency magnetic field, pulsed magnetic field, and drop.

Explain the downstairs friend, conduction is disturbance voltage, radiation is divided into magnetic field radiation, space radiation, I don't know what he means by pulsed magnetic field is anti-radiation interference?

en55015

Conduction is disturbance voltage, radiation is divided into magnetic field radiation, and space radiation.

1. Low power of a single LED. In order to obtain high power, multiple parallel uses are required.

2. Low color rendering index.

The color displayed under LED illumination is not as real as that of incandescent lamps, which is a technical problem to be analyzed from the spectral distribution.

3 light spots. Due to the defects in the manufacturing process of the white LED itself and the matching error with the reflector or lens, it is easy to cause the problem of "yellow circle".

4. The problem of LED irradiation uniformity.

If there is no secondary optical design, the irradiation of LED lighting products is relatively concentrated, so it is necessary to carry out secondary optical design to make its light intensity distribution map bat-shaped.

5 LED light decay problem.

After the LED is lit for a period of time, its light intensity will be lower than the original light intensity.

6. Compared with low-power LEDs, the light attenuation of high-power LED street lamps will be much better.

However, the heat emitted by low-power LEDs is very small. The high-power LED has the problem that there is no way to solve the heat dissipation, and the brightness will be significantly reduced after heating, so the power cannot be increased.

Now as long as the products for export are protected by EMC, most of the products sold for domestic sales are also protected by this protection!

We're already doing this right now.

Street lights also need to save energy. The choice of energy-saving street lamp controller for lamp networking, that is, LED street lamp, can save a lot of power consumption. Solar LED street lamp uses sunlight as energy, solar panels charge the battery during the day, and the battery supplies power to the lamp source through the intelligent controller at night, without complex and expensive pipeline laying, and the layout of the lamp can be adjusted arbitrarily, which is safe, energy-saving and pollution-free.

Compared with ordinary street lights, each lamp saves more than 1,000 kWh of electricity per year.
