The LED lighting fixture industry in penetrating

As the LED lighting market grows beyond single color and color-changing applications into general illumination applications such as residential, commercial and off-grid applications, and ultimately into outdoor area applications, it is forecast to exceed $5 billion in 2012, corresponding to a compound annual growth rate of 28% from 2008 to 2012, according to a recent report.The report notes this will be only the beginning for the ultimate replacement of conventional light sources, including high-efficiency fluorescent and HID fixtures. However, many challenges face the led high bay light industry to accomplish that goals. The report offers a detailed assessment of the market drivers and challenges faced by the LED lighting fixture industry in penetrating the general illumination market. It provides application analyses and forecasts for nine lighting market segments through 2012.

Through 2007, LED lighting applications included niche markets such as exit signs, architectural lighting, accent and decorative lighting, and entertainment lighting, many of which used red, green, and blue LEDs. However, white LED fixtures have begun to capture a strong market position in selected applications such as consumer portable lighting and solar landscape lighting, and more recently have begun to be used on a limited basis in applications such as retail display lighting, commercial and industrial lighting, and outdoor area lighting.In 2008, white LED fixtures accounted for just over 50% of the total LED lighting fixture market. The penetration of white LED lighting fixtures into general illumination applications will accelerate when such fixtures offer quantifiable energy and cost savings relative to the use of conventional light sources.

In recent years, LED technology has made impressive performance gains, which in turn have improved the efficacy of led high bay light lighting fixtures. In the forecast period 2008-2012, white LED fixtures will make gains in market share as the best commercially available high-performance white LEDs move beyond luminous efficacies of 100 l/W.Further improvements in designing fixtures that can optimize LED operation are expected to drive the growth in LED lighting fixture market. Both recessionary pressures and mass manufacturing will further reduce the cost.

LED which is running at a temperature

The RCD series have two independent dimming inputs: a PWM control that allows simple interfacing with microprocessors and digital controllers and an analogue voltage input that is suitable for lighting controllers or rheostat dimmers. Both dimming inputs are linear and the dimming range covers 0%-100%. The PWM input can also be used to shut down the converter to draw only 200μA from the supply.Incorporated in 1975 led high bay light Electronic GmbH originally was a supplier for high precision metal- film- resistors and- networks, becoming a pioneer for miniature DC/DC-converters in the mid 1980’s. Today RECOM is a leading supplier of converters in the power range from 0.25 Watt to 60 Watt and above. Their core focus- development & design, production and marketing span three continents - America, Europe and Asia, thereby ensuring close proximity to the customer base worldwide.

The Energy Star guideline for lumen maintenance requires that after actually running for 6,000 hours, an LED which is running at a temperature that is equivalent to what it would be in a luminaire, must maintains 91.8% of its brightness, or 94.1% of its brightness for outdoor commercial or residential settings. However, after an actual test of 6,000 hours for Luxeon Rebel LEDs running at 350 mA at 55 degrees Celsius, the LEDs maintained 99% of their lumen output.

The results reinforce the superior lumen maintenance performance that has been a hallmark of Luxeon LEDs since they were introduced in 2000, They reflect the ability of the materials used to build Luxeon LEDs — including those used in the Epitaxial process, the phosphors, and the lens and packaging materials — to withstand the rigors of use and the elements to which they might be exposed under a variety of conditions without degrading the led high bay light output too rapidly.Neo Neon’s LED Streetlights in Sweden were firstly installed in Kjellbergsgatan, J?nk?ping Municipality, and have now been in use for two years. The reaction of the public and the Municipality has been very positive. Because of many successful projects completed by RBIecolight, Neo-Neon now has many projects which they are evaluating with clients in a number of different countries.

the illuminated floor is a branded architectural application

The SSL2101 also offers non-isolated and isolated solutions in one chip. It has an additional input that can be used to detect demagnetization of the inductive element, ensuring full utilization of the magnetic material and preventing hard switching of the current. The device has in-built circuitry to reduce capacitive switch-on losses and optimize valley switching efficiencies therefore making the SSL2101 an effective power converter at low power levels. The SSL2101 uses on-time mode control and frequency control to control the LED brightness. This combined effect of both frequency variation and on-time control results in a dimming curve similar to that of an incandescent lamp. The usage of both control methods also enables the designer to reduce peak current, helping in the reduction of audible transformer or inductor noise.

The IC offers a reliable and safe thermal solution via a thermal enhanced package with a built-in Over Temperature Protection (OTP). It also features Short-Winding Protection (SWP), Over Current Protection (OCP) and is aligned with regulations on safety and power factor.The floor elements will be assembled like a jigsaw puzzle in less than four days, and was the highlight of the new showroom of UAE-based furniture giant Pan Emirates, which is situated next to the Mall of the Emirates. Almost 15 000 LEDs were used for this project. The red, green and blue color-changing LEDs have an expected lifespan of 10 to 15 years. The color settings and animation are controlled by an in-house developed computer system.

Kubik MD Dirk Durnez says that the illuminated floor is a branded architectural application that will not only set any desired mood in a venue, but will also allow clients to highlight products and showcase product launches and promotional events. He notes that the illuminated floor is a true marketing tool. They believe this will set a new trend in the way architects, interior designers and showroom designers design shops and shop-windows. The Kubik floor allows brands to stage their products.Kubik finance director Jean-Michel Koenig says they are convinced that the world's largest color-changing floor will boost awareness of this new approach in shop and showroom design, as well as architecture and interior design for corporate, commercial and even private use.

offering customers a broad range of pricing options from name brand

Manager of Dialight’s Optical Design Group, calculates the bottom line benefits for SafeSite end users like Rio Tinto and Valero: “Making a one-to-one comparison between a 100W SafeSite 250 Series fixture and a 250W HPS fixture in use 24/7, we calculate that over a year a typical plant with 1,000 retro-fitted Series 250 fixtures can save US$164,000 on energy at today’s prices.But it’s actually better than that,” he adds. “These T4 and T5 rated led high bay light don’t require a warm-up period and can be operated as ‘instant-on’, reaching full light intensity in a fraction of a second, so the plant could save a lot more by powering down the lights when not needed or using motion control to avoid running them 24/7. On top of that they’d have the added benefit of SafeSite’s 5-year warranty and that means zero maintenance and more cost reduction.

The new tool addresses the requirements of the “Chromaticity and Spatial Uniformity” test in the yahamlighting specification for led high bay light that requires the beam of light to appear the same color to the human eye, regardless of which area of the beam the viewer looks at or where they are at in relation to the light source.To show compliance with these requirements, the lighting manufacturer must have their product tested by an independent laboratory. The lab tests will produce a data set showing the color of the light output under a wide variety of conditions. In many cases, the lighting manufacturer must undergo a difficult and time-consuming process to analyze the data set and perform complex calculations to demonstrate or determine compliance.

the LED current for best luminosity

It not only can maximize light output and distribution, but can prevente harmful glare and reflections, the company says this ring light can be used for a wide variety of inspection, assembly, and rework applications. Its pure-white LED light makes it well-suited for inspecting circuit boards, surface cracks and defects, welds, solder joints, flux residues, and hairline stress cracks.It employs 80 high-output led high bay light that draw only 18 W of energy and produce up to 5800 footcandles of illuminance at a working distance of 4.5”. The LEDs are distributed among two concentric rings of lights, each containing 40 LEDs, and are controlled using eight quadrant switches. A color temperature of 6000 K, combined with dimming to 15% output, enables the ring light to be used with digital equipment, such as Luxo’s System 373 trinocular microscopes. What’s more, the ring light’s lamp life of 50,000 hours makes it an energy-efficient replacement for conventional 150-W fiber-optic illuminators.

 The former monitors the in-situ temperature on each LED and independently optimizes the LED current for best luminosity vs. temperature performance. The latter ensures a low drop out voltage on each LED channel of typically 25mV across the full operating current range. To minimize standby current, the LDS8160 also features an additional low-power standby mode, where the supply voltage of the device is switched to 1.8V. The LDS8160 is controlled through a high-speed I2C interface. Targeted at mobile backlighting applications, the LDS8160 supports up to six white LEDs or up to two RGB LEDs, with a maximum current of 25mA per channel.

Mobile phones have evolved from voice-centric devices to multi-media platforms. Users now expect excellent outdoor display readability, which is a challenge given the current required to drive the led high bay light unit to satisfactory display contrast and color saturation. One solution to this problem is to utilize RGB diodes in the backlight unit. These diodes require temperature compensation in order to keep their white color coordinates constant, a problem that the LDS8160 is designed to solve.
