ClearGuide Technology: A breakthrough in outdoor lighting

There are several things that are important to consider when looking for outdoor urban lighting. Typically, performance and design are on top of the list. It’s all about achieving a well-lit space to attract pedestrians, provide safe walking and gathering spaces, while complimenting the environment and architecture. With all the options out there, this may not be an easy task.

And some of you might still struggle whether to use traditional technologies such as HID or make the switch to LED. Each have their unique pros and cons and we’ll try to help you to pick the right solution for your needs. We are aware that you may know this already, LEDs are not new to the outdoor urban lighting market, but a refresher might not be a bad thing!

So let’s face it, the advantages of HID is that it’s a known technology. You can relamp existing luminaires without laying out heavy investment for new products and new technology. It’s considered less expensive than LED. But the biggest disadvantages are that it consumes significantly more energy than LED, and you get minimal control capability (on/off option only). Lack of dimming and controllability are potential drawbacks to non-LED technologies. We could still list tons of other disadvantages, but let’s stop here for the purpose of this article.

Let’s now look at the advantages of LED: better control of the lumen distribution, higher level of controls solutions to provide greater savings and asset management, and of course lower energy and maintenance costs over the life of the system. And this is only the tip of the iceberg! On the other hand, LEDs are still considered to be expensive when compared to traditional sources. And depending on the application, mounting height, and luminaire design, direct view LEDs can be considered too bright and “glary”.

Most outdoor LED urban luminaires use a horizontally mounted LED board, where the LEDs are pointed down, and optics are used to bend light in the desired direction. LEDs create a point source effect that can lead to glare, and may not illuminate the entire globe. Several methods are used to mitigate glare, including frosted coatings, indirect lighting, and even dimming. Each of these methods has a valid function (and/or aesthetic) but also may result in lowered lumens, and thus reduced performance.

Philips brings something new to the outdoor LED urban lighting market: a clear solution in a vertically oriented light engine. ClearGuide technology takes the benefits of solid state lighting and eliminates the “pixelization” often associated with an LED light source(s). By using a highly engineered vertical light guide designed with precision rings, ClearGuide eliminates the objections commonly associated with pedestrian scale LED luminaires.

By providing several different styles of post tops with complimentary bollards, Philips Lumec ClassicStyle and SleekVision families featuring ClearGuide technology combine the best of all worlds. Great luminaire design for both traditional and contemporary architecture, all of the solid state lighting and controls benefits, without the harsh brightness of seeing the individual LEDs.
