Technology of LED improved quickly this year. In order to provide more excellent products for our custoemrs, Lighting Orient release 100lm/w LED chips for all of our products.

Thanks to 100lm/w LED chips, efficiency of fixtures can be 85-90lm/w. It’s much higher than CFL and mercury lamps. We believe it’s a big step for improvement of LED lighting.

If you are interested in our 100lm/w products, please feel free to contact us here http://www.ledlightsorient.com/contact_us.html.

Thank you for support and trust from our customers from all over the world. Our products have been sold to

North America: USA and Canada.

Center America: Jamaica and EL Salvador

South America: Venezuela and Chile

Europe: German, Frence, Spain, Cyprus, Bulgaria, Ireland and Iceland

More: Australia, New zealand, French Polynesia, Iran, South Africa, India and so on. (more…)

It’s not just about the kilowatts.
Most people are now aware of one key benefit of LED lighting - its efficiency. LED lighting long ago surpassed incandescent efficiency and is now approaching and even surpassing the efficiency of linear fluorescent and metal halide. However, there are many other benefits to LEDs including lasting five to 10 times longer than fluorescents, consuming less energy while on, are fully dimmable, contain no hazardous mercury, are nearly unbreakable, are free of annoying flicker and buzz and are safer, operating on low voltage DC, with no glass or vacuum.
Facilities that are already implementing LED systems are likely not doing so in general illumination applications. LEDs are no longer just for task or accent lighting or color-changing architectural effects, but are now being built into fixtures that are tackling some of the most challenging applications in general lighting, and they’re competing with very-efficient linear fluorescent and very-bright HID. Some LED performance examples include parking garage fixtures from multiple suppliers that deliver more than 6,400 effective lumens while consuming 77 watts, high bay fixtures with 18,000 usable lumens that consume about 190 watts and troffers with 5,000 effective lumens that consume just over 50 watts.

The junction temperature of high-power LEDs can directly affect the performance and longevity of some LED devices. As the junction temperature rises, a significant loss of output (luminosity) can be expected. The forward voltage of an LED is also dependent on the junction temperature. As the temperature rises, the forward voltage decreases, which can cause excessive current drain on other LEDs in the array. This in-turn leads to thermal runaway conditions and ultimately to the failure of the device. High temperatures can also affect the wavelength of an LED fabricated using gallium arsenide, gallium nitride or silicon carbide. (more…)

During LightFair (North America’s annual largest trade show of architectural and commercial lighting ) 2008, most attendees were caught up in the waves of excitement and opportunity washing in and around the booths featuring LEDs and LED fixtures, reports JULIE MACSHANE.

More than 19,800 attendees flooded LightFair 2008, and it seemed like most spent their time pooling in the booths of LED exhibitors. Once there, architects, designers and specifiers jammed together in the small spaces and asked big questions about using LEDs in their products and applications: How bright? What colors? How much money can I save? Many visitors were looking at LEDs as the long-term lighting strategy to save energy and thus money, a more urgent quest with the price of oil rising ever higher.

Flashlights was widely used in many fields, such as hike, camping, and outdoor sports. It’s necessary for many people. If you want to buy a new flashlights now, you have many choice. Flashlights can be divided into three types, traditional flashlights(Incandescent), LED flashlights, HID flashlights. HID is less common. So your choice is between traditional flashlights and LED flashlights.

What are main difference of them?

Traditional flashlights use bulbs which contain a heated-up coil of tungsten wire. It gives off light energy with heat. The bulbs are usually filled with argon with Halogen.  In higher quality models, Xenon is also used.  LED flashlights use light-emitting diodes (LEDs) instead of Traditional light bulbs. LED is the one which bring so many advantages.
