Guide to Shop Indoor Wall Mounted Led Lights in ALLTOP Lighting

To say the development of scenery complementary street light, is also fit the national conditions of our country, the national development and social progress in speed, needs and provide place is also a lot of energy, energy loss is serious, the development of renewable energy is a must in our country, the development of the natural scenery complementary street lamp can be quickly realize energy conservation and emissions reduction, plays an important role in the development of our country.

Is certainly the way scenery complementary will not pollute the environment, has the strong complementarity and adaptability.

Is not subject to geographical restrictions and the limitation of climate, whether it is sunny or cloudy cloudy, or heavy snow in the winter rainy spring, scenery complementary street lamp can run normally, don't use other conventional energy sources, clean environment.

For such a street lamp, can relieve the energy crisis, to promote social progress and promote the development of country better.

Some say, since the development of scenery complementary street lamp is so important to the development of our country, it should immediately nationwide use of scenery complementary street lamp.

Is widely used all over the country to make scenery complementary street lamps, according to the current development now or try to, is not to say that the installation immediately.

This need to start the local governments at various levels and various in scenery complementary street lamp manufacturers work together to complete.

The development of LED market is unstoppable. In my opinion, in the future 3-
Traditional lighting will be completely shuffled within 5 years, said Chen Nan, general manager of the engineering management division of Huizhou Rex Optoelectronics Technology Co. , Ltd.
First of all, from the perspective of products, a few years ago, LED lighting products were expensive and ordinary consumers could not afford them.
Now, the price of LED has dropped rapidly, and it has penetrated into various fields such as outdoor and indoor with the speed of Superman's accident.
At the same time, in this rapid process, there are also phenomena such as uneven quality and messy market.
Different from traditional lighting products, LED products cannot be regarded as pure lighting brands. Its light sources are classified as semiconductors, which intersect with electrical technology and application technology, at the same time, the structure, heat dissipation and energy waste reduction of lamps also have technical and application experience requirements.
Therefore, product reshuffle is also the final trend of LED technology development, and the development of crude products will end.
With the investment in research and development of enterprises, once mature LED products fall to the ground, prices fall to the ground and product reshuffle will follow suit.
From the perspective of industry development, in the past, no matter whether you understand this line, various people and capital rushed into the LED lighting market.
Colleagues who have participated in this year's Guangzhou Guangya Exhibition have deep feelings. The development of LED is not only limited to the needs of the lighting industry, but will continue to develop in the direction of intelligence or IT.
Therefore, the living space of small enterprises that only assembled in the ancient town in the past will further shrink.
However, under the background of abundant funds, traditional lighting enterprises can only achieve sustainable development in the future if they invest in product research and development and integrate their own specificity, cultural concepts and channels, and this is the final direction of the industry reshuffle.

Human visual organs mainly by eyes, optic nerve, and related parts of the brain.

The structure of the human eye as shown, eyes like a camera, it's the pupil like the iris of the camera, around the iris pupil aperture effect, it can adjust the size of the pupil, according to the strength of the light to control the amount of light entering the eye.

The lens like the lens of the camera, it will be outside scenery focus imaging in the retina.

Is in one of the sensitive photoreceptors in the retina, it will feel to convey information through the optic nerve to the brain's visual center, the formation of light and shade, color, shape, dynamic, far or near, such as visual perception, in order to get information of the outside world.


there are two kinds of photoreceptor cells of the retina, is opposite in the central part of the pupil distribution dense cones, in the central part is mainly around the rods.

About 8 million cones, and there are three, respectively red, green and blue three areas in the spectrum of light reaction.
About 1 and rods.

200 million, its high sensitivity, can feel faint light.

In the bright light environment, brightness is more than a few CD/m2 (
Candela per square metre)

, rod cells lose the activity, mainly plays a role of main photoreceptor cone cells, then the visual call photopic vision.

Ming visual characteristics is to distinguish the color of the visual, and the objects on the discrimination ability of the details are accurate.

Then the eyes of wavelength of 555 nm green light sensitivity is the highest.

With wavelength decreases and gradually increase, the sensitivity were reduced gradually, until the end of the 380 nm and 780 nm, sensitivity to zero, which does not produce light.

When in a very dark environment, brightness is less than a few percent CD/m2, cones lose activity, resume the function of light-sensitive rods, then visual call scotopic vision.

Its characteristic is only can distinguish between light and shade, and no color feeling, and the ability to identify objects on the details of the greatly reduced.

Scotopic vision to the wavelength of 507 nm radiation has the highest sensitivity.

Between the above two situations, people in the dark and is not very dark, and as the vast 'twilight', the vision of people called the middle visual.

The high brightness can also distinguish between colors, brightness is lower only light and shade.

High pressure sodium lamp and metal halide lamp based on the strong penetration ability of the fog and the advantages of the ultra high luminous flux favor by lighting area, even in recent years, the LED energy-saving products in the lighting industry has the potential of a presumptuous guest usurps the host's role, but it is hard to replace sodium lamp or metal halide lamp, not




high pressure sodium lamp and metal halide lamp
Metal halide lamp by metal vapor (
For example, mercury)
And halide (
Such as dysprosium, sodium, thallium, indium and other elements of the halide)

Decomposition of a mixture of radiation and the glowing gas discharge lamp.

Relying on its own strong penetration ability of the fog and the advantages of the ultra high luminous flux by lighting field, even in recent years, the LED energy-saving products in the lighting industry has the potential of a presumptuous guest usurps the host's role, but it is hard to replace sodium lamp or metal halide lamp (
Metal halide lamp (

Metal Halide Lamp）

Is ac power, working in mercury and rare metal halide mixture vapor arc discharge in glowing discharge lamp, metal halide lamp is on the basis of high pressure mercury lamp add various metal halide made of the third generation light source.
】

, can't deny the advantages of these two kinds of lamps and lanterns does have its existence value.

The most commonly used to sodium lamp or metal halide lamp power is 250 w, 400 w, 1000 w, the lamps and lanterns of the power configuration is among the highest in the frequency on the light pole, the reason is very simple, because of its high brightness, illumination, and has a certain ability to penetrate the fog, on either side of the road lighting installation sodium lamp or metal halide lamp is good.

So here we have to come up with a question, that is installed on the light pole cast light lamps will be struck by lightning solar garden lights?
When it comes to lightning 【

Is accompanied by lightning of the thunder and lightning and thunder of a discharge phenomenon.
】

Hit on the phenomenon, let a person have to LED lamps and lanterns of lamps and lanterns, because the LED lamps and lanterns fruit peels was killed by a bolt of lightning strike bad examples.




high pressure sodium lamp any objects are the same, want to bad, or was killed by a bolt of lightning strike is the only way to the ground, LED lamps and lanterns is very easy to hit the bad is because of the constant current source inside the lamp without grounding, if don't want to say, caused by damage of the LED lamps and lanterns is natural lightning is inevitable, that also have to admit that it has been for installation personnel in the installation of lamps and lanterns of lightning damage lamps and lanterns has created favorable conditions.

The overall structure and the luminescent principle of LED lamps and lanterns with high pressure sodium lamp are completely different, that their lightning-proof ability will be the same?

The answer is yes, of course not, high pressure sodium lamp or metal halide lamp was killed by a bolt of lightning strike bad case is annals are numbered.

After open the sodium lamp cover can be very intuitive see, terminal has a total of three holes, left and right sides of the zero line and the line of fire, in the middle of the ground, the terminal service terminal can clearly see the ground after the card is with the lamp shell is a body, which is as long as the install lamps and lanterns on the street lamp or light, the light itself is grounded, the equivalent of lamps and lanterns is grounded, so even if the lamps and lanterns in the ground terminal is not grounded is doesn't matter, all may not be lightning strike.

Light, but not all of the metal halide lamp and sodium lamp project-light lamp do not need ground under any circumstances, use a separate grounding line depends on the fixed carrier, if it is installed on the steel bar, that's not ground wire is no problem, but if installed on the high walls or concrete pole is another matter, because the object is not a good electrical conductor, installed in the position to the lamps and lanterns to the ground terminal derivation from the underground to safety.
So everything should according to the actual.

The Jiangsu Provincial Economic and Information Commission, the National Development and Reform Commission and other six departments recently issued the 'Opinions on Accelerating the development of the semiconductor lighting industry. '
