LED Traffic Signal Lighting from Osram Opto Semiconductors Provides Safety for Pedestrians

07 May

With the help of “Light Line”, a warning light installed in the pavement, crossing the road becomes safer for pedestrians: in parallel to the switch function for the LED traffic light, “Light Line” uses a red or green signal to show whether the street can be crossed without danger or not. The warning light was developed by DSTA, a Spanish company that designs and manufacture LED solutions for traffic, lighting and transports. The signals in the various colors are provided by light emitting diodes from OSRAM Opto Semiconductors.

Particularly at less busy traffic periods, pedestrians often step onto a road crossing when the traffic light has already switched to red. This does not always have a happy ending. To reduce the resulting number of accidents, DSTA, the Spanish producer of light systems, has developed a solution with its “Light Line”, signalling to the pedestrian directly at his or her feet, additionally to the normal traffic light, whether it is possible to cross without danger. The warning light is integrated into the pavement and functions on a synchronous basis with the traffic light switch system: if the traffic light switches to red, the “Light Line” also switches to red and warns the pedestrian. As soon as the traffic light is showing green again, the “Light Line” also turns green. The double light signal is intended to bring about a higher level of attentiveness among pedestrians, prompting them not to cross the road when the signal is red, even if no vehicles are to be seen at that moment. To get a rapid and reliable light signal, DSTA is opting for red and green Golden Dragon LEDs from OSRAM Opto Semiconductors. These provide operate times in the nanosecond range; thus there are no delays in switching over and there is a gain in safety for the pedestrians.

Greater safety at the path of protection

Golden Dragon LEDs from OSRAM Opto Semiconductors can make avail of all their strengths in the innovative Light-Line solution: LEDs are very robust, defying jolts, wind and weather, as well as accumulations of dirt on the pavement. Thanks to the small construction size of the modules, it is possible to have very flat designs for the luminaires, a factor which also offers the opportunity of a problem-free retrofit installation. The decisive factor for DSTA was the low level of maintenance workload required by the LED: depending on environmental conditions, Golden Dragon LEDs have an average operating lifetime of up to 100,000 hours. This keeps maintenance costs very low and traffic is scarcely influenced as a result. Thanks to its low power requirement, in providing a high quality of light, the product is also a particularly efficient solution.

First test installations of the “Light Line” are in place in the Spanish cities of Burgos and Terrasa; further projects are to be launched in the near future. “Cost efficiency is an important factor, which is why more and more municipalities are opting for this LED system when it comes to pedestrian safety“, observes Ramón Fernández Morales, Business Development Manager at DSTA. “Golden Dragon LEDs are particularly economical and are the optimum solution for us, thanks to their energy efficiency and their low maintenance requirement.”


Incandescent vs. CFL vs. LED Light Bulb

07 May

For anyone out there dragging their feet about switching to Compact Fluorescent (CFL) or LED light bulbs in the home, I’ve done some research and put together some data about long-term usage in comparison to incandescent bulbs. As anyone paying attention has noticed, incandescent bulbs are rapidly becoming a thing of the past in terms of price, output, and performance. In an attempt to shed some light on the issue, we’ve crunched some numbers and put together an Excel sheet that compares various facets of incandescent, CFL and LED bulbs. Read the rest of our analysis after the jump, and feel free to download our Light Bulb Comparison Spreadsheet, which you can customize for your own home bulb comparisons.

Next time you’re out looking for light bulbs for your home, consider your options and bear in mind a few factors that go into differentiating your options: individual bulb price, lifespan, lumens (brightness), and wattage/electricity cost (how much electricity it takes to light the bulb). Before you try to figure out which bulb you want to buy, consider what your goals are. Do you want to the longest-lasting bulb you can find? Do you want the most efficient bulb? Do you want to stop changing bulbs for 15 years? These days, there’s an option for each of these concerns.

The incandescent bulb is a dinosaur. About the only thing it has going for it in comparison to more efficient and longer-lasting options is that the price of an individual bulb is still comparatively low. But if you use a little foresight, you’ll realize there are better options out there that cost just a little more. If you want a bulb that’s going to last for extended periods between replacements, you’ll want to go with the LED. The bulb features a lifespan of 60,000 hours versus the CFL’s 10,000 hours and the incandescent bulb’s 1,500 hours. Considering the bulb’s low energy expenditure, the cost (over its 60,000-hour lifespan) is significantly lower than either of the other bulbs. Simply put, if using as little energy as possible is your goal, the LED bulb is for you.

Of course, the standard LED is generally less bright than a traditional bulb. We tested the Spotlight LED bulb, which is made by the same manufacturer as the bulb we compared in our analysis (but with a lower lumen count), and we found it to have only a slightly less brightness than the traditional bulb. The LED also has the major drawback of featuring a very direct field of light, which makes it most useful only when aimed directly at what you want to light. Standard floor and table lamps equipped with an LED tend to offer streams of light aimed at the ceiling, which may not help with that book you’re reading.

As a versatile bulb that burns comparably bright to a standard incandescent, but still costs less over the long term and burns more efficiently, the CFL Bulb may be your best bet. An advantage the CFL has over the LED is an upfront-cost that is considerably lower and far closer to the incandescent. In fact, if overall cost is your only concern, the cost of new LED bulbs may be more than you want to spend. Over the life of an LED, you are only going to see dramatic savings over the CFL if you are in an area that has high energy costs. For example, we compared LED and CFL bulbs at a standard $0.10 rate, and found that you would save about $11 over 60,000 hours. We also compared the two at $0.33 (what a friend pays) where the savings jumps to $120 over the life of an LED.

While the CFL is twice as expensive as the incandescent upfront, the former buries the latter in a pile of long-term cost. Each individual setting—not to mention the user’s view’s on energy conservation—is going to call for a unique bulb. We’ve tried to give you basic data and tools to figure out which bulb is right for you. Download the Excel spreadsheet and consider the best options for you.
