Ottawa, ON (PRWEB) November 19, 2014
Leapfrog Lighting, already a leader in spec-quality LED lamps for specialized business purposes, today announced a higher-efficiency, lower cost Energy Star certified PAR series. The new bulbs immediately replace the previous industry-standard PAR bulbs from the innovative companyknown for stringent quality, and especially light quality.
"This is really pushing light quality and light output to the next level," explained Stephen Naor, CEO of Leapfrog Lighting. "We're committed to constantly refining our spec-quality bulbs. Ultra consistent color temperature control is a given with our PAR bulbs. Our new line also increases efficiency, with greater lumens output and output per watt at a lower cost."
With 18 models available for each bulb style and with a choice of CRIs of 81 or 95even the most demanding business or display application can be implemented. Leapfrog Lightings PAR bulbs are popular with art galleries, museums and high-end retail stores where environment and product display is critical. CRI is a quantitative measure of a bulbs ability to reproduce colors faithfully.
"This isn't about revolutionary change," explained Mr. Naor. "Our PAR line was already among the best for what we call Total Light Quality. We're nuancing what was already a top performing lamp."
The bulbs are generally suited for any application where color consistency and display quality is critical, but is also often chosen for pleasing office environments, general household lighting or for any suitable fixture where consistent quality is desirable.
"Yes, these are among the most efficient bulbs on the market," explained Mr. Naor. "But our PAR line is designed for anyone who wants that efficiency without compromising color, consistency, light quality."
Minimum expected lifetime is 40,000 hours. All bulbs are dimmable, and flicker free down to 10% light output.
The Energy Star certification applies to the 3000K versions of the bulbs in all of PAR 20, 30 and 38. These 3000K bulbs are available with various CRIs and beam angles (from 24 degrees to 60 degrees)18 models available. All bulbs, are UL certified.
The bulbs are distributed through some select distributors, and direct to customers and trades. They are also available online in the Leapfrog Lighting shop.

Houseplants are popular indoor decorations. Attractive and constantly changing, they add a softness of line and provide a bit of nature indoors. However, the ideal location of a plant for decoration may not be the ideal spot for plant growth. Lack of adequate light is the most common factor limiting the growth of plants in many areas of the home. Supplementary electric lighting is usually the easiest and least expensive way to provide enough light for plants that do not receive adequate natural light (Figure 1).
Figure 1 Artificial lighting, if properly designed, allows plants to be grown indoors in nearly any setting.
Light provides the energy plants need to make the food required for them to grow and flower. Plants are the only organisms able to use light to produce sugars, starches and other substances needed by them as well as by other living organisms.
Certain colors in light rays are important for proper plant growth. Leaves reflect and derive little energy from many of the yellow and green rays of the visible spectrum. Yet the red and blue parts of the light spectrum are the most important energy sources for plants, and plants require more rays from the red range than from the blue.
Plants growing outdoors, in greenhouses or close to windows are exposed to a natural balance of the blue and red light rays that plants need. Where plants receive little or no natural light, you must provide additional light from artificial sources.
As a single light source for plants, incandescent light bulbs are not particularly good. They are a good source of red rays but a poor source of blue. They produce too much heat for most plants and, if used, must be located some distance from the plants, thus reducing the intensity of the light the plants receive. They are also about one-third as efficient as fluorescent tubes in converting electrical energy to light. Furthermore, a standard incandescent bulb's life is often only about 1,000 hours, whereas a fluorescent tube's life is normally 10,000 hours or more.
Fluorescent tubes provide one of the best artificial light sources available for plants in the home. Other light sources such as sodium-vapor and metal halide lamps may be used but are not as readily available or adaptable for home use.
Fluorescent tubes are made in many sizes and shapes: circular, U-shaped, square or straight. Straight tubes in 2-, 4- or 8-foot lengths are used most frequently.
Many indoor gardeners use cool-white fluorescent tubes. Warm-white fluorescent tubes also seem fairly effective, but fluorescent tubes listed as white or daylight are less desirable for indoor plant growth. Cool-white tubes produce a small amount of red rays in addition to orange, yellow-green and blue rays. However, the red light produced usually is not enough for plants unless windows or other artificial lights produce additional red rays.

When the 2014 Nobel Prize in physics was awarded this October to three Japanese-born scientists for the invention of blue light emitting diodes (LEDs), the prize committee declared LED lamps would light the 21st century. Now researchers from the Netherlands have found a novel way to ensure the lights of the future not only are energy efficient but also emit a cozy warmth.
"We demonstrated a seemingly simple - but in fact sophisticated - way to create LED lights that change in a natural way to a cozy, warm white color when dimmed," said Hugo Cornelissen, a principal scientist in the Optics Research Department at Philips Research Eindhoven, a corporate scientific research entity owned by the company Royal Philips in the Netherlands.
Cornelissen and his colleagues from the Eindhoven University of Technology, Netherlands describe their new LEDs in a paper published today in The Optical Society's (OSA) open-access journal Optics Express.
Incandescent lamps naturally emit warmer colors when dimmed, and Cornelissen said our general preference for redder colors in low-light situations might even have developed far back in time, when humans "experienced the daily rhythm of sunrise, bright daylight at noon, and sunset, each with their corresponding color temperatures."
LEDs, however, don't normally change color at different light intensities. Other groups have used multiple color LEDs and complex control circuitry to make lights that turn redder as the power is turned down. The added complexity comes with its drawbacks: multiple components can increase the cost and the risk of failure, and mixing the light from multiple LEDs without creating color shadows and other light artifacts is a tricky business.
The Dutch research team tried an entirely different approach to creating cozy LEDs. The scientists had noticed that when they embedded LEDs in coated textiles or transparent materials, the color of the emitted light would sometimes change.
"After finding the root cause of these effects and quantitatively understanding the observed color shift, we thought of a way to turn the undesired color changes into a beneficial feature," said Cornelissen.
Starting with White LEDs
They began with cold white LEDs, which can be made from blue LEDs surrounded by a material known as a phosphor. Part of the blue light is absorbed by the phosphor and re-emitted at a different color. The multiple colors combine to form white light.

November 13, 2014 // Paul Buckley
Samsung Electronics Co., Ltd., has introduced chip-on-board (COB) LED package products, the LC006B and LC008B, with six and eight watts of power respectively.
The new packages join five others in Samsungs LC series (LC013B, LC019B, LC026B, LC033B and LC040B), to complete the company's COB package line-up.
A chip-on-board LED package provides a single light source that combines multiple LED chips to achieve higher light intensity and uniformity, while simplifying luminaire design.
The LC006B and LC008B offer high-efficacy levels of 140 lm/W and 142 lm/W at 5000K CCT, respectively. The new packages will support a wide range of CCT (Correlated Color Temperature) specifications from 2700K to 5000K with a CRI (Color Rendering Index) over 80. The devices also feature a compact package size with an 8 mm LES (Light Emitting Surface) and a package structure that can be easily connected with holders or screw mounts for greater installation convenience.
Samsung COB LED lighting solutions now can be used in a wider range of applications, including downlight for home lighting, flood light for industrial lighting, and spotlight and downlight for commercial lighting.
