Now many factory buildings are all steel structure, generally this kind of factory buildings using LED high bay lights more, because the irradiation distance of LED high bay lights are far, to achieve reasonable lighting conditions, LED high bay lights are the most appropriate choice! There are also many factory buildings using ordinary energy-saving lights, disadvantage of these energy-saving lights "save electricity but not money" in the use. Some enterprises mark the light power standard highly, but can not up to; the brightness of the lights are good in the beginning of the use, but soon grew dark, and life is very short.
Energy saving and emission reduction is a basic requirement for domestic industrial lighting now, is also in line with the development of enterprise interests. To achieve energy-saving and emission reduction must be given more attention on the type of the factory lighting, so as to ensure good lighting conditions, can effectively improve the work efficiency of staff in enterprise. So enterpris must pay more attention to choosing industrial lighting.
In the era of the rise of LED lighting, LED high bay lights has entered various factories, each workshops in the actual application. There are still some
First, glare.
Second, impression of space. The light emitted by current LED high bay lights basicly vertical downward, most of the LED light fixtures are with aluminum cover, due to the brightness of LED chip surface is high, so the top of the factory building is very dark, so that creates a sharp contrast between the light below and the light above, give a person a heavy sense of oppression, resulting in lack of impression of space.
Third, because now chips of LED high bay lights used by many factories are using the way of single tile, so there will be spot for each single light in industrial lighting, a large integrated chip will generate a lot of spot, making the object illuminated by the lights appear more obvious ghost.
Fourth, the problem of reflection, because the LED is mainly direct light, together with the plant worktop mostly metal materials, a lot of light will be directly into the human eyes, greatly reducing the work comfort of the workers, so some people will feel uncomfortable when factories using LED lighting. In fact, the color rendering index of LED high bay light is obvious, but also far ahead in energy efficiency, and now the main problem is concentrated in the comfortable sensation of the work environment, which is the the aspects of improvement that LED high bay light manufacturers need to strengthen.
As mentioned above, LED high bay lights used by factory is also a lack of basic research in the application process, the lighting requirements of traditional high bay lights achieve through the reflector, and LED products achieve lightin through the the lens and reflector in the middle. However, due to the study of the lens is not very mature, and more are moved traditional high bay lights to imitate, which makes the problem of glaring and unilluminating.

Badminton, table tennis and other types of balls are multi-directional, multi-angle flighting in the air, players playing the balls are multi-angle, making multi-phase movement at different speeds, it is always a process of tracking, capturing and focused imaging between the human eyes and the badminton and table tennis. The process of playing the ball is the process of tracking the ball flight path and aerial positioning.
For indoor badminton, table tennis, basketball, volleyball, tennis and other sports stadium lights. There are a number of lighting effect indicators should be reached. However, from the practical point of view in practical exercise, for the civil fitness indoor stadium with leisure and fitness, lighting quality level should not be adopt a unitary standard of rigid indicators. According to the investment situation, playing level of players etc. many other technical and economic factors, determined by the investment operators in a reasonable range.
Meeting the use is practical, practical is good. A lot of stadium lighting cases of indoor badminton, table tennis, basketball, volleyball, tennis show that: indoor lighting of civil stadium with fitness function which grasping the following five aspects of lighting quality, lighting effects can reach a certain level, will be able to meet playing exercise requirements.
Indoor stadium lights should be no glare.
Once there is glare in badminton, table tennis, basketball, volleyball and other indoor stadium lighting, multiple locations and different angles of stadium will produce glare. Players can only see a strong stimulation of light, but can not see the flying ball, produced dazzling or discomfort visual effects in the visual system.
Indoor stadium lights should be no stroboscopic effect.
At present, in badminton, table tennis, basketball, volleyball and other indoor stadium lighting, the stadium lights widely used are metal halide lights, bar lights, ordinary high-power energy-saving lights and so on. They have varying degrees of stroboscopic and stroboscopic effect.
Indoor stadium lights should be high color performance.
Lights only are bright, it is also important that light should with color. Light is just the founder of the colorful world. The principle of visual physiology reveals that light energy acts on the human visual organs, not only in the visual perception system to produce bright sense, but also to produce a sense of color. In the bright visual state, the bright sense corresponds to the intensity of the light energy, and the color sense corresponds to the wavelength of the light energy.
Indoor stadium lights should be the sun color.
Sunlight radiated to the ground are mainly three parts of UV-light, visible light, infrared light. UV-light and infrared light are invisible to the human eye, the light that the human eye can see is visible spectrum.
Indoor stadium lights should be energy saving.
The economic and technical objectives that indoor stadium lights in badminton, table tennis, basketball, volleyball, tennis and other stadium lighting should pursued is to achieve the most bright, clear, true and comfortable lighting quality in the most reasonable investment in lighting fixtures and minimum lighting operating costs.
In current, there are many lights can be used for indoor stadium lighting, such as J-series LED stadium lights in Hangzhou ZGSM, we have great advantages in price, technical performance, the number of lights used in stadium, lighting effects and so on. We are leading in the field of lighting.
Lighting fixtures refer to a device that capable of light transmitting, distributing, and changing the light distribution, including all the components necessary for securing and protecting the light source, in addition to the light source, the wiring accessories are necessary for connection to the power source. Lighting fixtures used in all aspects of our lives, and we can do nothing without it in our daily life, the progress of mankind and social production also can not be separated from it. Various types of Lighting fixtures on the market, but outdoor LED lighting is a relatively wide application of lighting fixtures. So, what matters should pay attention to on installation of outdoor lighting fixtures?
Work environment of outdoor LED lighting fixtures:
As the working environment is more complex, effected by the temperature, ultraviolet, humidity, rainy days, dust, chemical gases and other natural conditions, environmental factors should be considered in the design of LED outdoor lighting fixtures.
Packaging technology of outdoor LED chips:
At present, domestic production of LED lighting fixtures (mainly street lights) are mostly used 1W LED strings, parallel assembly, this method is called packaging technology. 30W, 50W or even larger modules to be assembled to achieve the required power, these LED packaging materials use epoxy resin package. The difference between the two is: epoxy resin package has a poor temperature resistance, easy to aging for a long time. Silicone packaging with a better temperature resistance, should pay attention to choice when use.
Matters should pay attention to in the choice of cooling materials for outdoor LED lighting fixtures:
Select aluminum or aluminum alloy with good thermal conductivity, copper or copper alloy, as well as other alloys.
Reserch in design of the radiator for outdoor LED lighting fixtures:
Clear the power that the LED lights need for thermal dissipation.
The type of thermal dissipation. Cost comparison: natural convection cooling with the lowest cost, strong wind cooling are medium, heat pipe cooling cost is higher, jet cooling with the highest cost.
Design of the radiator parameters: thermal conductivity of metal, chips, radiator, Air thermal resistance of ambient air and so on.
Calculate the volume, area, and shape of the radiator.
At room temperature of 39 ℃ - 40 ℃, whether the temperature of the lighting fixtures meet the cooling requirements, if not met, then recalculate and adjust.
Determine the maximum permissible operating temperature of the outdoor LED lighting fixtures.
Waterproof, dustproof, anti-aging, stainless steel bolt fastening, and then in accordance with the promulgation of China's latest outdoor lighting technical specifications, as well as urban road lighting design standards.
In recent years, LED lighting industry is becoming mature in Europe, the United States, Japan and other places, China's domestic market competition tends to white-hot, and turn into the era of fighting the scale, fighting the price. The establishment of the ASEAN Community and the promotion of the strategy of "The Belt and Road Initiative", leaving LED lights manufacturers increasing the attention rate in Southeast Asia and Egypt, Israel, Saudi Arabia and Turkey etc. "The Belt and Road Initiative" national market year by year.
Turkey is another booming emerging economy after "BRIC countries", China, Russia, India, Brazil and South Africa. It enjoys the reputation of "Next Eleven" in the international community and has become the member of "Economic Security Council" G20. According to data from 2016, Turkey's economy grew by a percent of 4.8, making it become one of the top five fastest-growing economies in the world.
With the construction of Silk Road economic belt and 21st century maritime Silk Road, China and Turkey once again in close contact, the two sides have a wider range of cooperation in the areas of frastructure construction, economic and trade. According to the latest data released by the Turkish Statistical Bureau, the first half of 2016, China-Turkey trade amounted to 13.716 billion US dollars, up to 0.73% year on year. Among them, Turkey imports 12.728 billion US dollars from China, up to 2.48% year on year, exports 989 million US dollars to China, low to 17.44% year on year. Data shows that China is the second largest trading partner for Turkey, the proportion of China and Turkey trade volume accounted for total foreign trade of Turkey rose 0.1%, China and Turkey trade deficit expanded 4.61% year on year.
On the LED lights industry, from the data of General Administration of Customs shows that in the first half of 2015, China's total exports of LED lighting
products about 50 billion US dollars, grow 16% compared with the first half of 2014 year on year, of which more than 45 million US dollars exported to Turkey. First half of 2016, China's top ten key areas of LED products exports amounted to 20.221 billion US dollars, of which the amount of exports of Turkey over 129 million, jumped to 28th.
With the development of the local economy, in recent years, productivity of the Turkish lighting industry has been greatly improved, but still the lack of LED lights manufacturers, LED technology is low, high production costs, unable to meet the local demand, mainly rely on imports, then brings business opportunities to overseas suppliers.
Due to the changment of government investment in outdoor lighting, the penetration rate of LED lighting will show an exponential rise in the next few years, replacing the traditional halogen lamps and incandescent lamps in rural areas. The data shows that the market size of current lighting and lighting market in Turkey is about 350 million US dollars. Research and Markets expects the Turkish LED market will grow at a compound annual growth rate of 15.6% from 2016 to 2022. By the the year of 2022, the market size will reach 344 million US dollars. In the Turkish market, LED signage and billboards are expected to have the highest growth rate.
In addition, because of its special geographical location, national manufacturers regard Turkey as a strategic market. Turkey across the Eurasian
continent, north of the Black Sea, south of the Mediterranean, west of the Aegean Sea, so the products exported to Turkey, can be exported to the Middle East, Europe and even Africa and other markets. Turkey has a customs union with the European Union, the EU is Turkey's traditional market; the transport only takes 6-11 days from Turkey to major European countries. Istanbul and Turkey share the European information in a large extent. By understanding the Turkish market, you can understand the latest European market letter, making enterprises seize the opportunity in the fierce competition.

There are many modern outdoor lighting styles that you should know:
LED street light
Road lighting is an important part of urban lighting, the traditional street lights often use the disadvantage of high-pressure sodium light that 360 degree luminous, light loss which caused by a huge waste of energy. LED street lights are different from conventional street lights, LED light source adopts low-voltage DC power supply. It is efficient, safe, energy-saving, environment-friendly, long life, quick response, high color rendering index, etc. unique advantages, can be widely used in roads.
Solar street light
Solar street lights adopt crystalline silicon solar battery-powered, store energy by non-maintenance VRLA battery (colloidal battery), ultra-bright LED lights as a light source, and controlled by the intelligent charge and discharge controller, used to replace the traditional utility lighting street lights. Have the advantages of high stability, long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving and environmental protection, economical and practical, and so on, no need to lay the cable, no AC power supply, no electricity; Can be widely used in urban primary and secondary roads, residential, factories, tourist attractions, car parks and other places.
Solar garden light
Solar garden light usually refers to the outdoor road lighting below 6 meters, the main components are: light sources, lamps, poles, flanges, base embedded, because of its diversity, beauty with the characteristics of landscaping and decorating environment, it is also known as the landscape garden lights. Mainly used in urban slow lane, narrow lane, residential area, tourist attractions, parks, squares and other outdoor lighting in public places, can extend people's outdoor activities time, improve property safety.
Tunnel Light
Tunnel light is to solve the "black hole effect" or "white hole effect" when vehicle into or out of the tunnel and the brightness of the sudden changing in the vision, used for the special lighting of tunnel lighting. Shell selectes alloy environmental protection materials with high strength and good toughness, transparent pieces are toughened glass, dust-proof, water-proof, corrosion-resistant and rust-proof. Has strong resistance to strong impact and impact capacity; Multi-channel anti-vibration structure and high-tech surface coating, a variety of close high-frequency vibration can not affect the light, and can work in the workshop, roadbed, rail and other high-frequency vibration and humidity, high temperature environment, long-term stability. Good electromagnetic compatibility, will not cause interference to the transmission network.
Traffic light
Traffic lights are divided into: motor vehicle lights, non-motor vehicle
lights, crosswalk lights, the direction indicator lights (arrow signal lights), lane lights, flash warning lights, road and rail plane crossing signal. According to the optical principle, red light with a long wavelength, strong ability of penetrating air, and more noticeable than other signals, so take it as the traffic signals of prohibition, and using green as an announcement signal, because the biggest difference between red and green, easy to distinguish. In addition, the color can also express some specific meaning, to express the heat or violent words, the strongest is red, followed by yellow. Green has a cold and calm meaning. Therefore, people often uses red represent the danger, yellow represents the warning, green represents safety.
led solar lights, as the name suggests, is the LED fixture use the sun light as main source energy, save up the electricity converted by the sun during the day, and output the current at night, making the lights lighting. led solar lights are green light fixtures which have the advantages of low installation cost, low maintenance costs, security, energy saving, intelligent control, stable and durable, etc., so favored by more and more engineering.
At present, the common types of LED solar lights are street lights, garden lights and lawn lights. Although the installation of LED solar lights has no geographical restrictions, but because of its energy source has a special nature, therefore, we need to pay attention to the following problems when installing lights:
As far as possible to choose a well-lit area. Due to the different latitude, height, climate and other factors, the effects of LED solar lights installation in different places are not the same. Such as, Tibet is the most abundant area of sunshine in China, therefore, the installation of solar lights in Tibet can make full use of local resources. On the contrary, solar lights can difficult to fully play its usefulness in the areas with more rainy season.
Avoid the occurrence of occlusion at the top of the lights. In the installation, must avoid the occurrence of occlusion at the top of the lights to ensure that the solar cell module to absorb and reserve energy, otherwise, will affect the use of lights at night.
Pay attention to the angle of the module of solar lights. When installating, we must ensure that the module of solar lights should be tilted fixed installation, the angle between the panel and the horizontal plane is about equal to increase 5 ~ 15 ° on the base of the latitude of installation location, to ensure that the absorption of light energy for solar panels.
However, whether a project should install LED solar lights, need related assessment by engineering, at the same time, to develop lighting programs according to the local conditions, fully integrate the local resources, so that the lamps can maximize its effectiveness.
Recently, the haze once again sweeping across the country, as the lighting enterprise, we can not change the environment, but can do small thing, so that people not can see only the lights but also the road when going out, Which requires increasing penetration of the LED street lights.
Color temperature selection of LED street lights
LED packaging process currently used through applying the phosphor with different excitation wavelengths, adjusting the amount or the proportion of phosphor to obtained white LED light source with different color temperature. Different light sources emit different color temperature, low color temperature light source is characterized by energy distribution, the red radiation is relatively more, usually called "warm light; After color temperature increasing, the proportion of blue radiation will be ncreased in the energy distribution, commonly referred to as "cold light." For white LED light, there is a relative more proportion in yellow for the low color temperature, however, there is a relative more proportion in blue for the high color temperature. From the human visual point of view, low color temperature gives a warm, stable feeling, and high color temperature gives a deserted, refreshing feeling.
The color temperature of some common light sources
In general, LED light sources can be divided into warm white, neutral white and cold white, three categories. The color temperature of traditional street lights are generally warm white light that about 2300K, the human eye vision will obviously feel yellow. LED can be produced different color temperature of the light source through the packaging process, give the road lighting a lot of different options.
The relationship between color temperature and light efficiency
It is noteworthy that, for the color temperature selection in the early group of LED lights, almost all manufacturers have chosen 6000K, or even more than 6000K, this is why? It turned out that under the technical conditions that the early phosphor, cool white LED light source with a higher light efficiency. Compared to color temperature, people pay more attention to the physical properties of light efficiency. The most important means to improve light efficiency is to improve the excitation efficiency of the phosphor, excitation efficiency of YAG yellow powder is much higher than the orange powder.
Higher color temperature can get higher light efficiency, light efficiency of 5500-6500K color temperature can enhance 48.7% than the warm white light source which less than 3500K. LED is energy-saving, entirely because the LED has a higher light efficiency than other light sources, put aside the energy efficiency and talking the energy-saving is meaningless.
High light efficiency not only bring higher energy efficiency, but also reduce the cost of lights, making the products more competitive. So most of the LED street light manufacturers select to producing the products with 6000K color temperature in order to pursue high energy-saving rate.
In recent years, LED technology is still high-speed developing, the light efficiency of chip continuously improve, energy efficiency rate has also been guaranteed. The contradiction between light efficiency and color temperature is no longer the main contradiction in the application process, and whether the color temperature and environmental conditions are coordinated is the focus should be paid attention. Synthesize technical conditions, climatic conditions, the current environmental conditions and the human eye senses, we propose, color temperature of LED street lights should choose the range of 3000 ~ 5700K. This color temperature will not have a large impact on light efficiency, but also to ensure the penetration of haze, and adapt to our people's visual senses.
