Properties of Light and How They’re Used in Architecture

If you’re a lighting manufacturer or supplier, you already know that light has a major effect on how a person experiences a space.

Did you know that architects and building engineers rely on these same principles and the science of lighting when designing a space? The main architectural principles of lighting can be broken down into three categories: light color, measuring light, and bouncing light.

Light Color

In architecture, the standard for white light is considered daylight at noon during the month of June. According to experts, Northern light is generally the most consistent and has more light at the blue end of the spectrum, while late afternoon light is more on the red end of the spectrum.

Measuring Light

Luminous Flux – This is the rate at which a light source emits light, measured in lumens.
Luminous Intensity – The measure of the light intensity that takes into account the amount of light and the amount of coverage. For example, a spot light and a flood light may emit the same high amount of lumens, but because the spot light is focused into a smaller cone, it has a much higher intensity. Intensity is measured in candelas or candlepower.
Illuminance – Illuminance is the amount of light that falls on a specific surface area. Measured in lux (metric) or foot candles (imperial – read more about foot candles here), a 1000 lumen spot light will illuminate a small area much more than a 1000 flood light because more lumens from a spot light are hitting the smaller surface.
Luminance – Luminance is the measure of an object’s brightness or the amount of light coming off an illuminated surface. This measurement is called a foot-lambert.

Don’t Forget to Consider Bouncing Light

When choosing fixtures and designing the space for optimal light, consider the reflections that will occur in the room depending on windows, furniture, and accessories (especially mirrors and other reflective surfaces).

Remember, besides the principles of lighting, choosing the right lighting for a residential or commercial space come down to how the space should physically feel (for example, the right lighting can make a room feel larger), and more lighting isn’t always better! Choosing the right lighting is the most important thing.

2021 Global LED Plant Lighting Market Will Exceed 2 Billion US Dollars

With the impact of global climate change and urbanization on traditional agriculture, the demand for plant lighting and energy consumption continues to expand. At the same time, with the maturity and popularity of LED lighting technology, LED lighting has also begun to integrate with agricultural applications. LED plant lighting has become the LED industry. A niche market. China’s LED plant industry has formed an industrial cluster, LED plant lighting has obvious advantages, will accelerate its market penetration, while the development of plant factories and the legalization of cannabis cultivation in the United States will further stimulate market demand.

The LED plant lighting industry cluster is distributed, and the Pearl River Delta is the largest industrial cluster area. At present, there are more than 150 enterprises involved in LED plant lighting in China, mainly distributed in the Pearl River Delta region, accounting for 60%, followed by the Yangtze River Delta region, accounting for 21%, and other regions accounting for 7%. Competition among local enterprises is not fierce, and they are still in the stage of R&D cooperation or demonstration and promotion. Any company in the future may stand out.

Lighting For Bonsai Trees

LED plant lights have obvious advantages and accelerate the occupation of the plant lighting market. At present, there are four major types of plant illumination sources on the market: LED lamps, fluorescent lamps, high-pressure sodium lamps, incandescent lamps, and halogen lamps. Traditional plant lamps are low in cost and therefore still used in plant lighting; LED lamps are emerging as plant lighting lamps. It is more energy-saving and environmentally friendly and has many advantages such as high luminous efficiency, low heat generation, small volume, long life, light quantity, and adjustable light quality. It has obvious advantages in the field of plant lighting. In terms of plant growth lamps, the market share of traditional types of plant lighting fixtures will gradually shrink in the next few years. It is expected that by 2021, the global LED plant growth lamp market will account for 60%.

The development of plant factories and the legalization of cannabis cultivation in the United States have injected more power into the development of LED plant lighting. Plant factories are the future trend and have received strong support from the agricultural departments of various countries. Zhongke Sanan, Mitsubishi Chemical, BOE, Panasonic and other domestic and foreign giants have invested heavily in plant factories. After the legalization of cannabis cultivation in the United States, the demand for small plant lighting systems will grow rapidly, both of which will drive the growth of LED plant lighting. It is estimated that by 2021, the global LED plant lighting system market will exceed 2 billion US dollars, including 490 million LED lamps.

How Office Lighting Affects Productivity

There are certain factors that everyone knows affect workplace productivity, but there is one important factor often overlooked by most employers across the globe: lighting. Sure, it’s common knowledge that reading in the dark can harm your eyes, but lighting has effects well beyond that, and an employer’s choice of lighting can have a significant impact on the productivity of her company.

Consider this: A study conducted by the American Society of Interior Design indicated that 68 percent of employees complain about the lighting situation in their offices. The fact that such a substantial number of employees disliked the lighting in their offices enough to complain about it implies that many employers could be making the same mistakes. The two most common scenarios for poor office lighting are lights that are too dim and lights that are too harsh.

The Drawbacks of Artificial Lighting
The first culprit, dim lights, can be detrimental to productivity for several reasons. First, dim lighting can cause eye strain and headaches, because, when lighting is inadequate, the eyes are forced to work much harder in order to see. Dim lighting can also result in drowsiness and lack of focus, which would obviously have a negative impact on employee motivation. The second culprit, harsh lighting, is much more common than dim lighting and is just as harmful. Florescent lighting, especially, has a number of negative effects on employees, as it has been known to cause eye strain, and it is also cited as a trigger for migraine headaches. This harsh lighting also makes it more difficult for the eye to focus, so alternatives should be sought whenever possible.

Natural Lighting as a Superior Alternative
The best alternative to harsh lighting and dim lighting systems is natural light itself. In a study conducted in Britain and published in “The Responsible Workplace,” it was shown that windows were the number one determinant of the occupants’ level of satisfaction with a building. This effect is due to lighting’s ability to affect the human body in two ways: directly, in the form of affecting what and how well we are able to see, and indirectly, in the form of effects on our mood, behavior, and even hormonal balance. Natural lighting renovations have been shown to result in happier workers, less absenteeism, and fewer illnesses, and, because better lighting encourages satisfaction among workers, it also results in increased productivity.

But just how much of an impact does improved lighting really have on the productivity of workers?

Proper Lighting’s Effect on Productivity
According to some studies, the impact is substantial, and, although the initial cost of a lighting renovation could seem daunting, the gains due to energy savings and- more importantly- productivity gains more than make up for the cost of the investment. Take the following case study for example: In the late 1980s, the lighting systems in the U.S. post office in Reno, Nevada were renovated to make them more worker friendly. The upgrade resulted in energy savings of about $50,000 per year, but the real improvements came in the form of employee productivity. Mail sorters in the facility became the most productive sorters in the western half of the country, machine operators boasted the lowest error rates, and the financial impact of the productivity increase was expected to boost revenue by approximately $500,000 per year. And this wasn’t an isolated incident. Countless other companies across the country have also noted productivity increases as the result of lighting renovations.

With light being a key component of vision, and vision being responsible for 80 to 85 percent of our perception of the world around us, it’s not difficult to see why ignoring proper lighting strategies in your office could have a significant negative impact on productivity. Harsh lighting and dim lighting are equally detrimental to the productivity of your workers, and, by opting instead for more natural lighting or other lighting systems that have been proven effective, you stand to not only save energy but also increase productivity among your business’s employees.
