Understanding the difference between Luminance and Illuminance

June 17, 2017 8:41 am

With the numerous advances in lighting technology, it can sometimes be tough to determine the right light source unless the basics of light are understood. The brightness of a lighting fixture is determined by the number of lumens produced. Technically, a lumen is a standard unit that measures the total amount of visible light emitted by a light source.  Many lighting manufacturers, purchasers, and users often evaluate fixtures brightness solely based on lumen output.  However, evaluating a LED lighting fixture on the basis of its lumen output can give users a distorted image of the fixture performance, as Lumen measures the light being emitted...

Harnessing the Art of Thermal Management

June 16, 2017 8:37 am

All light sources transform electric power into radiant energy and heat in various proportions. According to the Wikipedia online encyclopedia, a 100-watt bulb is 2.1% efficient, which means it produces about 2 watts of light and 98 watts of heat, whereas fluorescent lamps are said to be about 8.2% efficient. Contrary to popular belief, high-power light emitting diodes (LEDs) generate a significant amount of heat and are not 100% efficient. Unlike traditional light sources, LEDs transmit heat instead of radiating it. Most of the heat from a LED goes upward into the fixture housing, which somehow needs to be dissipated...

LED Innovators – Looking Ahead

June 15, 2017 8:33 am

There is a revolution in the lighting industry, and the catalyst is light-emitting diode technology (LED). Over the last decade, advancement in LEDs performance has been nothing less than phenomenal. The rapidly emerging LED technology already seems to outperform the traditional lighting technology, but innovators are still constantly looking forth to develop far better and cost-efficient technologies. One reason that high-performance LEDs are relatively expensive now is that they are typically made by layering various compounds onto a sapphire substrate. Shuji Nakamura developed a method of growing thin GaN layers on sapphire substrates in the early 1990s, and till now...

The Next Generation High Bay/Low Bay Lighting

June 14, 2017 8:17 am

The business executives across industries are increasingly looking for strategies to reduce cost and save money wherever possible. For many businesses, transforming from obsolete lighting to new LED lighting solution can be an attractive and ultimately cost-saving alternative. Businesses are increasingly buying and retrofitting the buildings with LED lightings that not just reduces the cost but also enhances the space. The accelerating adoption of LED lighting is changing the way manufacturers develop new products. While businesses are shifting to typical T-tubes as an alternative to traditional lighting sources, manufacturers have come up with new LED lighting solution that is far...

Tunable LED lighting technology captures the spotlight at LightFair

June 13, 2017 8:59 am

  Smart lighting and the Internet of Things (IoT) may have been the most prevalent theme at LightFair International (LFI), but the tunable white LED technology was close behind and of course inherently requires some form of lighting controls to set color and intensity. Some of the most compelling examples of tunable solid-state lighting (SSL) came from Visa Lighting, Acuity Brands, and Philips Lighting. The tunable lighting, a form of human-centric lighting (HCL), promises to deliver enhanced well-being for humans. SSL applications varying from healthcare to educational to office settings can leverage tunable LED technology for impacts including increased worker...

Power of Internet of things

Internet of things Smart cities 10 billion people will inhabit our planet by 2050. Two-thirds of them in cities. We won’t just need more light. We’ll need LED lighting that’s energy-efficient and sustainable. Enabling cities to benefit from connected lighting systems and data-driven insights to become more livable and resilient. Public lighting plays a unique role, because it transforms the visual appearance of places, and can make urban areas accessible, usable, and safe...

Minimize Workplace Accidents with LED Lightings

June 12, 2017 8:01 am

Lighting, along with a number of other factors, contributes to safe and healthy working environment. However, poor workplace illumination is often overlooked by companies. Poor lighting not only has a negative impact on employee productivity but can also pose a serious workplace hazard. According to International Labour Organisation (ILO), globally, more than 2.3 million deaths occur per year as a result of accidents at work or work-related diseases. Apart from the human tragedy and wider consequence, there are also significant economic and business costs related to accidents. The ILO estimates the cost of workplace accidents to be around 4% of...

LEDs Core Components and Products Build In U.S.A

June 12, 2017 7:57 am

LED market has attracted a plenty of new entrants in recent year. As the market for LED lighting continues to grow, suppliers are competing to capture the market share at low price point. While the competition is forcing prices down, the rise of illegal and inferior products on the market has increased the product quality concerns. The lighting market is flooded with products manufactured in overseas, where regulatory standards are lower and labor are cheap. A LED unit’s chip is vital to its functionality, as the quality of the chip used can significantly affect the service life of the unit....

Smart Lighting – Smart Future

June 9, 2017 9:03 am

Today, lighting is more about an experience than just illuminating a given space. We live in the era of the Internet of Things which allows us to control, customize and transform our personal environment. Smart lighting is now perceived as part of the Internet-of-Things (IoT) and not just as any other lighting system. LED technology has emerged as the key to new smart lighting technologies. Smart lighting brings in a new level of comfort and convenience to our lives. The human-centric smart light in our homes and workplaces keeps us healthier, happier and more productive. Smart lighting enables us to...

Solid State Lighting: A highly Energy Efficient Lighting

June 8, 2017 8:20 am

  Electricity comprises a large portion of overall energy usage in any nation. According to U.S. Energy Information Administration (EIA), United States consumed about 412 billion kilowatt-hours of electricity for lighting function in a residential and commercial sector. This accounts for 15% of the total electricity consumed by both sectors and about 11% of total U.S. electricity consumption for the year 2014. Energy Efficient Lighting Today, there is increasing demand for energy-efficient and environmentally friendly lighting system. Solid-state lighting is an emerging technology with the potential to improve the lighting system and significantly lower the energy usage and the cost....
