Ricoman’s Liang Gao takes a closer look at some of the often neglected features and bene๏ฌts of installing LED lighting.
The lighting industry has undoubtedly entered a new and exciting era: that of LED lighting. While the early adopters have already embraced the use of LED lighting technology, many through direct replacement, there are a number of โwhite elephantโ factors that should be considered. Taking these parameters into consideration can make the decision to switch to LED lighting even smarter and more efficient. In this article, I aim to discuss these simple and often neglected factors.
Lighting performance
This refers to the basic photometric parameters of the light ๏ฌttings being installed, for example the efficacy (lm/W) and the beam angle of the luminaires. While almost everyone pays attention to these parameters, not everyone fully understands their implications.
Traditionally, the CAT 2 Louvre ๏ฌttings with 4x18w ๏ฌuorescent tubes have been widely popular as office luminaires in the UK. Many lighting consultants and contractors embraced these ๏ฌttings when they were ๏ฌrst introduced for their high efficiency, sophisticated design and glare-reducing features. However, there were also drawbacks, such as the difficulty to maintain and clean (especially back in the days when
smoking in public areas was still permitted) and the unpleasant shadows on the wall, owing to restricted beam angles.
In this case, the efficiency and beam angle of the luminaires were sacri๏ฌced for a better anti-glare rating. In addition, the ๏ฌttings were also noticeably thick, and thus unsuitable for places with restricted ceil void. So, the user should always be aware that by using a luminaire with well-balanced speci๏ฌcations, there is always scope to reduce the quantity of ๏ฌttings required.
With the emergence of LED lighting, manufacturers are able to create light ๏ฌttings that etch closer to offer the best of both worlds. Which means luminaires with slimmer pro๏ฌles, offering higher efficiency,
efficacy, a wider spread of light and minimum glare factor.
“With the emergence of LED lighting, manufacturers are able to create light ๏ฌttings that etch closer to offer the best of both worlds.”
For example, the Ricoman Prism Panel, with its micro-prismatic diffuser and internal structure at under 13mm thick, offers high efficacy at over 85 lumen/W. It also features IP54 rating, wide beam angle at 120ยฐ and under 19 UGR for low glaring rating. All these bene๏ฌts make it a truly well balanced all-rounder. The use of 36W Ricoman Prism LED Panels, replacing four 18W luminaires, reduces the quantity of luminaires required by 20%, providing further savings on top of the normal energy savings from using LED technology, while maintaining high illuminance levels and uniformity in the open office areas.
Product features
Solid state lighting offers the lighting industry unprecedented opportunities to create more innovative and pioneering ๏ฌttings that are truly designed and engineered for purpose. Unfortunately, this ideology has not been adopted by everyone, and many manufacturers are still being reactive to market needs by simply replacing light sources from traditional lighting luminaires with LED light sources. In other words, they tend to ignore the vast potential regarding product and industrial design possibilities opened up by solid state lighting. So, itโs very important for buyers and users of LED lighting products to understand and utilise innovative design features that can result in fewer ๏ฌttings being required.
Similarly to what happens with LED Panels, an industrial 
environment using 400w HQI-T discharge lamps in the luminaires may well be replaced with a 200W LED luminaire design, leading to a reduction in the number of luminaires used.
Taking Ricomanโs Canopus Low Bay for example, rather than directly replacing traditional low bay with Ricomanโs fittings, the installer/user may also be able to reduce the quantity of fittings required in certain situations (e.g. aisles of warehouses) by utilising the LED modules on the Canopus low bay, which also offers great uniformity, efficacy and low glare rating. The tiltable LED modules can essentially transform the Canopus low bay into a unique 160ยฐ luminaire.
Conclusion
LED lighting is here to stay. However, there is still room for improvement towards further exploring and utilising possibilities offered to achieve cost savings. Companies with the best chances to win this battle are those investing in good industry knowledge, research and development.
