We deserve LED lighting

As an environmental enthusiasts, and now facing to increasingly unusual weather ,I have to say a few words, I am so shock and sad that I heard the Oklahoma hurricanes killed nearly one hundred live life two days ago, including more than thirty children. Hurricane is formed in Atlantic and eastern North Pacific where a strong and deep tropical cyclone form. Obviously, increasing greenhouse effect warming enhanced the formation of hurricanes and ultimately lead to serious consequences. How to mitigate the greenhouse effect has become a big puzzle.Image
 We have been promoting low-carbon environment life, we should save water and electricity in daily life, such as turning off lights and display, tap tightly closed after use, etc. These subtle movements are worthy of our attention, especially electricity, maybe there are a lot of people would ask, saving electricity is really important to us? I can certainly tell you that, definitely, why? Because the main culprit of the greenhouse effect is carbon dioxide, carbon dioxide is often produced by the burning of coal power generation, so saving electricity can indirectly lead to a reduction of carbon dioxide emissions. In the United States, coal-fired power plants provide about 46% of the electricity. Visible, saving electricity is the main way to mitigate the greenhouse effect, the Earth Hour each year on March is the most typical example to promote reducing energy consumption. However, just turning off the lights for one hour can not solve the fundamental problem, we need energy saving and environmentally friendly lighting. Recently, LED lighting has emerged as time required
 
LED lighting uses semiconductor lighting, which is the biggest characteristic compared to energy-saving lamps and fluorescent lamps. It e effectively reduce the waste of energy into heat energy which is produced by incandescent tungsten in luminescent light and inert gas in fluorescent light, can promote more energy into light energy , so you can save energy. Meanwhile, the semiconductor light emits no infrared and ultraviolet light, and prevent light pollution generated by the inert gas and the tungsten. Most importantly, LED lighting adopt DC drives, it can convert the alternating current into direct current, maximum to avoid emitting fluorescent and incandescent AC strobe irritation the human eye, so the green also played a big role .
 
Indeed, this is the principal of all LED lighting. Now a more extensive application of the LED flood light has appeared in decorative lighting and other outdoor venues. Because of his unique octahedral structure and a point light source, ensuring that he has a wide range of lighting features, and it uses high voltage constant current driver so that it emits high brightness light. Moreover, its unique glass shade and light body is made of aluminum alloy material with high thermal conductivity, the surface electrostatic sprays high heat dissipation material, these features also guarantees a unique waterproof, dustproof, shock, lighting, high definition and good heat dissipation characteristics, it can be widely applied to outdoor spaces such as squares, stadiums, parks, fountains, tables and aerial vehicles and aircraft factory lamps which require high brightness lighting, it has long lighting life and is difficult to damage ensure that it is commit to saving manpower and material resources and reducing the financial investment.

Of course, a good professional LED lighting requires professional team to build, Li Sida lighting http://www.lead-lighting.com precisely can provide you with more ahead of other sectors of the professional LED lighting, he is continuing its efforts to improve the presence of LED lighting defect and join him to create a more environmentally friendly energy-efficient LED lighting, we look forward to more specialized companies like Li Sida lighting that produce mass consumption of high-quality LED products, I firmly believe that we stay away from natural disasters on the day when all traditional bulbs replaced by LED bulb,you deserve LED lighting.

big-wave surfer

“Falling wasn’t an option,” was the thought running through the mind of big-wave surfer and waterman Mark Healey as he rode this wave. “Teahupoo is truly one of the wonders of the world. I’ve been making an annual pilgrimage to there for the past 17 years.”

What kind of light bulb saves more energy?

Obviously,LED light is our best answer. Now it is so popular and widely used in our daily life, we choose LED light instead of any others,what is the unique advantage compare to other lamps such fluorescent lamp. Let me explain to you
 
As we all know,the LED light is the third generation lighting product  superior to any others  because it is special in energy saving and environmental protection. Why?It adopts semiconductor lighting, which is ahead of the tungsten filament in incandescent and inert gases in energy-saving lamps In the case of the same current, the heat can be converted less, it greatly improve the utilization of energy, that’s why it prefers to save energy. The semiconductor does not produce unique infrared and ultraviolet light, greatly reduce light pollution, in the constant pressure driven conditions, it directly convert AC into DC, so it is different with fluorescent and LED lighting, energy saving lamps, which generated flicker by frequent changes in the frequency of the alternating current, stimulate the human eye, it can be environmentally friendly.
 
Now LED flood light is popular in LED lighting, it is widely used in outdoor landscape lighting, because it uses highly integrated COB as light source, ensure high lighting intensity relative to other products, its unique design lampshade octahedron and light design so that it can irradiate all directions, and the LED floodlight with high thermal conductivity aluminum alloy and high heat dissipation lamp body inside the spray material, lampshades is made ​​of high quality tempered glass, all of these features bring that LED floodlights is major in shock-resistant  and heat-resistant, waterproof and dustproof and good freshness, radiation characteristics, therefore it is widely welcomed in outdoor lighting, such as squares, parks, stadiums, airports, operating table, aerial vehicles, stage, tall buildings, etc. in vitro need to use LED Floodlights.
 
With the LED lighting is hot on the market, more and more enterprises have been taking participate in the LED lighting. Often a handful master the core technology, Li Sida lighting http://www.lead-lighting.com is one of a representative. Excellent quality and professional R & D and manufacturing staff  are devoting their effort to create more leading peer LED lighting

Where is LED lighting applied in daily life

1, building exterior lighting
There is nothing better than the LED flood light whose shape is square or round so that it can control beam angle in projection area of ​​the building, which is exactly the same as the traditional floodlights. However, because of the small, thin LED light source, the development of linear LED projection lamp will undoubtedly become the major attraction, because there is no place to put overhangs traditional floodlight in many of the buildings. It’s easy to install, can also be installed in a vertical level, better integrate with the building surface,it has brought new lighting vocabulary to lighting designers. Nowadays,it has been expanding the creative space and making impact on the modern architecture and historic buildings lighting techniques.
2, Landscape Lighting
The LED light isn’t similar to the sources of traditional lighting which mostly has glass bubble shell, it can well integrated to urban street furniture It can be lighten on recreational space in the city, such as paths, stairs, decks, waterfront, garden for lighting. For flowers or low shrubs, you can use LED as a light source to illumination. Hidden LED Floodlights will be particularly favored. Fixed end plug can be designed, according to the height of plant growth, we can facilitate adjustment.
3, logo and indication of lighting
It can be used on space-limited or guide places, such as road pavement separated display, stair stepping local lighting, emergency exit instructions lighting, you can use the appropriate surface brightness LED self-luminous buried lights or other lamps embedded in the vertical wall, such as indicator lights on the ground or guide light by the seat side in theater audience hall, as well as shopping center floor guide lights. In addition, compared to neon, because its voltage is low, there is no fragile glass, does not increase production costs because of bend, it is worth promoting the use of the logo design.
4, the interior display lighting
Take lighting quality for example, because the LED light source has no heat, ultraviolet and infrared radiation, exhibits or merchandise will not cause harm, compared to traditional light sources, lighting does not require additional filter, lighting system is simple, inexpensive, easy to install. The precise distribution light can be used as a substitute for fiber optic lighting in museum. Commercial metropolis use the colored LED lighting,white LED interior decoration is to provide auxiliary lighting, hidden light band can use LED, particularly advantageous for low space.
Image5, entertainment and stage lighting
As the LED dynamic, digital control color, brightness and dimming, lively saturated colors can create both static and dynamic lighting effects. Whole spectrum from white to any color, LED’s use of lighting opens up new ideas on such space. Long life, high lumen maintenance value (10,000 hours remained 90% lumen), and compared to PAR lamps and metal halide 50, whose life is 250 hours reduce maintenance costs and replacement of light frequencies. In addition, LED overcome the metal halide  color shift after a period of use. Compared with PAR light, it has no heat radiation, can make the space more comfortable. Currently LED color wall decorating in the restaurant construction application has become common practice.
6, the video screen
Full-color LED display is the world’s most spectacular large display device in the open , it use advanced digital video processing technology, a large area with unparalleled high brightness. Depending on the indoor and outdoor environments, using a variety of light-emitting pixels, to achieve different brightness, color, resolution, in order to meet a variety of purposes. It can dynamically display graphic animation information, use of multimedia technology, can play all kinds of multimedia files. The world’s most influential LED display, comes as the U.S. Manhattan Times Square New York Stock Exchange, using a total of 18,677,760 LED, an area of ​​10,736 square feet. Screen can be divided into multiple screens, but also showed that the Wall Street stock market at a glance presented in front of the public. Another rise in Shanghai Pudong Lujiazui Financial Center in Aurora International Headquarters, the entire facade of the building facing the Puxi bordered 100m long oversized LED screen, total area of ​​3600 square meters. Called the world’s first.
7, combined with industrial design
LED is the darling of product designers in Europe in recent years, they consider LED can be used as part of product design elements, surf in the imagination of space, light, glass or other materials together and become beautiful works of art.
With LED lighting gradually penetrated into the daily life, his charm is also growing, he has much more worthy of development and application areas, let us join hands together with Li Sida http://www.lead-lighting.com to create better tomorrow of LED lighting

How to choose LED lighting

With the LED products have been increasingly strengthened awareness of low-carbon environment, people pay more and more attention to lighting products, especially LED products due to its high energy saving and environmental protection, has been widely supported in our daily life, but our concern is how to choose good LED lighting products that is suitable for us.As long as we follow these criteria to judge. Choosing good LED lighting will not be a puzzle.

1, product packaging

(1) whether there is product trademarks and certification marks.

For example: 3C certification, CE certification, UL certification, GS certification, in addition to, trademark printing quality of high-quality products is good, clear with a soft damp cloth, if it has clearly markedit can’t be easily erased.

(2) whether the product’s rated voltage range color temperature, precautions, safety instructions, applicable environmental , etc. are marked clearly,

2, product price comparison

Due to LED lamps special production process, the cost is relatively high. The average domestic price of LED lights are in the forty to fifty or more, imports is higher.

3, the appearance of the product

First whether the appearance of the product is very rough. glue is cleaned or not, whether or not a fixed screw protrude on plane? If the color of the screw is consistent with the outermost shell

4, the lighting inspection

When lamp is lightened  we should  carefully observe color changes, if, the yellow light trun into white light in a short time, or a white light into a white light with blue color, we have to give up such products, because there two possibilities in it case: one: power problems; two: LED light source selection is turnovers. In addition, the color of the lamp must be positive, lamp light color does not flash. After LED lighting is started, we can detect the heat by contacting with the product surface temperature, and if the product surface temperature continue to rise in one hour, rather than a maximum temperature stabilized at 30 minutes, then do not select the product, thermal reasons results in reducing product life.Image

The lighting time of LED flood light is longer than other LED lights, has been applied to outdoor long decorative lighting, its unique glass shade and light aluminum body coated with high thermal conductivity and high heat dissipation material ensure it has advantage of waterproof dustproof and high heat dissipation capability, but it can not guarantee its quality must be excellent, according to above particular we can also judged it is good or bad, of course, it is difficult to find good professional lighting companies ahead of peers, Li Sida lighting www. lead-lighting.com is undoubtedly one of theseIt is known as its high quality products and unique product and has been praising by domestic and foreign for a long time.
