With the full spectrum of sunlight

The latest innovation in LED development is called NF2W757GT-F1 Optisolis. The full-spectrum LED from world market leader Nichia is capable of generating a light spectrum that comes closest to that of the sun. This is achieved by a revolutionary new phosphor technology and a special blue LED chip. The spectrum of the 420nm chip contains almost no UV emissions and in combination with the phosphor achieves a CRI value of almost 100.

A main application to Optisolis application is Human Centric Lighting - a special type of lighting that adapts to the human inner clock and thus to the biorhythm. In addition, Optisolis can be used wherever an extremely high CRI is required, e.g. in operating theatres in hospitals.

Manufacturers can utilize Optisolis™ and trust in a spectrum where all colors are reproduced to the color seen under a standard light. (Figure 1) Also, color rendering index has been significantly improved compared with the current products for general lighting. (Figure 2) Most importantly, since UV emission is essentially non-existent in the spectrum, the degradation of irradiated materials can be reduced dramatically compared to that of other light sources containing UV emission, including other market available LEDs.

Target applications include Museum and Art Gallery Lighting, where the highest CRI is preferred, but UV radiation and light sources can be detrimental. Additional applications could include Color Evaluation（e.g. painting, printing), Commercial Lighting (e.g. retail, etc.) or anywhere Ultra-High CRI is desired.

The Optisolis family consists of two series, the NF2W757G-F1 and NF2L757G-F1. Both series are housed in a 3 x 3 x 0.65mm package.

Features:

• CRI: 95
• Typical luminous flux:
  - NF2W757G-F1: 23.0lm at 65mA
  - NF2L757G-F1: 24.1lm at 65mA
• Max. forward voltage: 3.3 V
• Radiation angle: 120 °
• +120°C maximum junction temperature

Applications of the Optisolis full-spectrum LED

• Museums and art galleries
• Hospitals
• Retail lighting
• Commercial Lighting

Middle Power LEDs are those that usually use less than 0.3 Watt of energy, are fairly small and require minimal or no cooling. Small as they are, they play a key role in the ever larger penetration of LED into the lighting market. This comes from the possibility to build arrays of middle power LEDs that deliver the required light output for a given form factor.

Thus, many of the popular applications of LED technology use modules with middle power LEDs. Among them: fluorescent LED replacements, LED lamps, LED linear modules for cove lighting, linear luminaries, LED panels, back-light modules for illuminated ceilings or signs.

Our Multibar Nichia LED modules bring a high degree of freedom and peace of mind to lighting and product designers.

The innovative modular design with plug&play connection system makes installing the Multibar into a linear light fixture or cove light a breeze. Short segments and 90 degree angles are not a problem.

Lets compare the CSP LEDs available on the market today, from leading LED manufactures. These are: Nichia, Samsung, Philips Lumileds and Seoul Semiconductor.

Our LED modules with tunable white technology are a strong foundation for Human Centric Lighting. You can dynamically manage their color temperature and brightness in order to simulate natural daylight across the period of a day, from a productive pure white in the morning to a cozy warm white in the evening. Human Centric Lighting has has proven to increase well-being, concentration and performance.

Usually, a light emitting diode (LED) has two key components, the LED chip that emits the light and the LED package which focuses it, enables assembly into lighting products and transfers the heat away to the heat sink.

Large LED manufactures design and build both LED chips and packaged LEDs. Small manufactures usually purchase LED chips and assemble them into packaged LEDs. This explains the enormous, sometimes confusing, variation in packed LEDs specification, performance and quality. Packaged LED attributes are defined by both chip and package design and production.

This picture has now got even more complicated with the increasing market penetration of Chip Scale Packaged LEDs, known as CSP or flip-chip LEDs.

If we consider a packaged LED to be the automobile with the LED chip its engine then a CSP LED is an engine on wheels, with minimum body work or other components.

Most of the products and services we use or consume have a unit of measurement. The kilograms of a bag of apples, litters of a bottle of water, meters of a roll of cable, hours of work are some common examples. Modern technology has introduced us to new units: gigahertz of processing power, kilowatts of energy consumption, gigabytes of storage or memory. All have one important thing in common: interested people have easy access to devices of measurement, crucial for quality control or fairness of a transaction.

The powerful BackMatrix LED modules are designed to provide optimum illumination to large areas. Luminous ceilings, walls or 3D elements will have a uniform lighting in color and intensity, with high spectrum quality and sufficient brightness.

For most of history, humans lived, worked and slept under the governance of natural light. The flickering light of candles was a poor substitute and did little to change the rhythm of life for all but the wealthy few.

Life went on under a dynamic light ,with changing tone and brightness, as a day went by and seasons changed. Then, one day, electric light was invented and everything changed. From that point forward a "golden hour" or "afternoon" could be at any time of day, on any point on the planet or beyond, outside or inside, from our living room to a windowless office or deep underground.

The beneficial trend to design lighting with focus on human nature and how natural light behaves has lead to the wide adoption of lines of light as a principal way to illuminate interiors. A line of light can be obtained via a light source hidden from view inside a cove in the wall or ceiling that illuminates an adjacent surface. Light is reflected from this surface into the space that has to be illuminated. That is why lines of light are commonly known as cove or indirect lighting. The allure is the similarity with natural light. With the proper light source used we could imagine that the cove is actually a hidden window to the outside from where sunlight flows in. This particular way to illuminate raises a particular set of challenges for the light fixtures used.
