Shop Best Flood Lamps in ALLTOP Lighting

We often say scenery complementary street light has the characteristics of environmental protection and energy saving, unlike conventional lights, which will produce pollution.

But they don't understand, conventional street lamp is just lighting of the city, how will to environmental pollution?

We use a digital example to tell you, for example, a city in the installed 150 sets of 250 w street light, electricity for 10 hours a day, the decade of electric power consumption for 1642500 degrees, coal consumption is 547.

5 tons, reduce 1434450 kg of carbon dioxide, sulphur dioxide, 4653.
75 kilograms, nitrogen oxides, 4051.
5 kg.

So great is the number of conventional lamps for how serious the pollution of the city, so we try to reduce the use of conventional street lamp.

The scenery complementary street lamp is on the social environment has a role of environmental protection, it is the use of solar and wind energy as an energy source, no harmful objects, and in time and geographical complementarities, wind-light complementary street lamp system is the best match on resources.

Scenery complementary street lamp can according to user's amount of electricity load and resource case with reasonable configuration of the system capacity, therefore, in order to reduce the pollution of the city, for people living environment bring some fresh atmosphere, we should choose to have the beautiful scenery of the green environmental protection, high efficiency and energy saving, safe and complementary lamps.

 road motor vehicle traffic and the pedestrian average illuminance is city road lighting one of the evaluation index, and street lamp configuration of an important reference index.

A city road to configure or replacement for the LED street lamp'

LED street lamp is made of street lamp, LED lamps and lanterns with high efficiency, safety, energy saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, the city lighting energy saving is of great significance.
】

First, technology will be involved in related index of the lighting calculation.
With 'utilization coefficient

Utilization factor is a face or other provisions of the reference plane, the luminous flux directly or by reflection to accept each other with the launch of the rated all lighting lamps and lanterns of the ratio of the total luminous flux.

'One of the method of calculation is more simple and effective method.

'Utilization coefficient method to calculate the formula of' absolute copying the traditional lighting theory research conclusion.

We have to do is to some experimental and theoretical data input formula of LED street lamp, get the results, and with the requirements of road lighting design standard reference.

It goes without saying that these calculations are LED street lamp design, development, improvement, improvement and marketing of necessity.
Utilization coefficient (
U)

Is directly on the road of the ratio of luminous flux, luminous flux and all source and the height of the street lamps and lanterns, elevation, arrangement, road width and so on.
Luminous flux (

2, light pole before operation, each part of the first check fasteners, lamp holder to install whether correct, light work is normal.
Then work in simple debugging system is normal;

Loosen the solar panels on the controller cable, light work;
Connected to the solar panel cables, light;

Careful observation of each indicator light on the controller changes at the same time;
Everything is normal, before lifting the installation.

3, the main light pole lifting, pay attention to safety;

Screw fastening absolutely good, sunrise Angle deviation, such as the component needs to adjust the direction of the sun completely up to end toward the south.

4, put the battery into the battery box, according to the technical requirements will be connected to the controller;

Connect the battery, and then pick up the load, and then answer the solar panels;

Connection operation is important to note that each terminal with indicated on the controller cannot be wrong, plus or minus two polarity can't collision, cannot meet the;
Otherwise the controller will be damaged.
5, the debugging system work is normal;
Loosen the controller solar panels on the wire, the light;
Connected to the solar panel cables, light;

Careful observation of each indicator light on the controller changes at the same time;
Everything is normal, can seal control box.

Chengdu plans to launch a & other;
Artificial moon & throughout;
It will light up the sky much within 50 miles.


it is reported that the object, called & other;
Lighting throughout satellite &;

The satellite will be deployed in 2020 over China's southwestern city of chengdu, allegedly eight times its brightness is true of the moon, projecting over the region a & other;
Evening light throughout the &;
。


there is no official details of the project, but they said the idea came from a French artist's inspiration.


it is reported that on October 10, chengdu aerospace science and technology institute of microelectronics system co. , LTD. , chairman Wu Chunfend at an event in chengdu has revealed the plan.


it will complement the moonlight after launch in 2020, the chengdu sky more bright, is likely to replace the traditional street lamp.


artificial moon can control light 10 to 80 km range area.


while this sounds unbelievable, but professor Wu said, the technology has been studied for many years, is now ready.


however, the plan finally achieving remains to be seen.


artificial moon in chengdu has been criticized by the skeptics and concerned citizens, they think this kind of light can cause negative effects on animals and astronomical observation.


but the Harbin industrial university institute of aviation optical institute, Kang Weimin said that this kind of light can only be issued & other
Like dusk light & throughout;
。


this is not the first time that human beings try to the sky reflect light objects, but in the past, most of such plans ended in failure.


last year, for example, a Russian team trying to deploy purportedly & other;

After the moon in the night sky of the brightest objects & throughout;

on July 14, 2017, Mayak in Baikonur space satellite launch site launch, carrying the soyuz 2.

1 a rocket launch, despite strong opposition, especially the importance of keeping from the dark night sky astronomers.


in the next few weeks after launch, amateur astronomers and scientists tracked its journey and found they think the spacecraft.


but in the same year in August, the execution of the project team found that reflector fails to work normally in orbit the sun.

Benefiting from the rapid growth of LED lighting and the introduction of Sapphire by consumer electronics, the demand for sapphire is expected to increase significantly in 2014, and Taiwan's production capacity is full of demand for price increases.
The retail price of LED bulbs fell in November, and the price reduction in China was obvious. The downward price was conducive to further stimulating market demand.
In 2014, the demand for LED bulb lamps and lamps increased by more than 80% annually, with high growth determined. 2013-
The year 2016 is the golden development period of LED lighting, and the penetration rate will increase from 20 to about 45. It is a rare industry with fast growth and high certainty.
The sales volume of LED lamps was about 0. 4 billion in 2012 and is expected to reach in 2013.
0. 7 billion, 2015 at noon on 2. 2 billion and 2016 on 3 billion. Of which 2012-The compound growth rate in 2016 was as high as 67.
Mainland is lighting products production factory 2013 have 60 of led lights by mainland production with LED lighting of have start mainland production LED lighting industry chain manufacturers will benefit.
