Benefits of LED parking and area lighting applications
Outdoor LED Lighting fixtures, such as LED Parking lot
lights, provide some excellent benefits for Parking and Area applications because
of how they GENERATE Commercial led lighting
and how they DISTRIBUTE light. Light Emitting Diodes generate light via a
semi-conductor, as opposed to the consumption of a “fuel source” like in HID
lamps. In regards to “distributing” light, LED fixtures commonly utilize
“Multi-Point” sources, meaning the fixtures have multiple diodes with
individual optics. When you compare this to the way most HID fixtures
distribute light (with a single bulb and reflectors within the fixture), the
result is light that is more evenly “distributed’ across a surface.
The three most common benefits of LED parking lot lights:
Energy Savings
Common wattages for Commercial led lighting
can range from 40 Watts to 600 Watts, often resulting in a 40%-60% reduction in
energy consumption. This is a result of how the light is generated (see above).
What this means for your facility is savings of up $300 per fixture, per year,
in electricity costs.
Maintenance Cost Reduction
Again, due to the way LED’s generate light, the way they
progress through their functional life is much different. Instead of ceasing to
function properly once a fuel source is significantly reduced, LED generated
light output degrades very slowly over time. As a result, the functional life
(often in excess of 100,000 hours) of an Commercial led lighting
can be significantly longer than that of an HID Lamp...which in turn
drastically reduces the costs for maintaining a Parking and Area fixture over a
longer period of time.
Lighting Performance
Moving on to the way LED fixtures “DISTRIBUTE” light: as a
result of the multi point design, LED outdoor lighting fixtures for Parking and
Area Lighting applications often provide a very evenly distributed light
pattern. What this means is that light levels across a given surface will vary
less as the distance from the pole or fixture changes. Commercial led lighting
often produce a “bright spot” directly underneath the fixture with light levels
decreasing drastically as the distance from the pole increases. LEDs mitigate
this problem through even distribution. The result, in regards to LED vs HID,
is a more even foot candle distribution from the LED conversion. In addition to
the even distribution of light, LEDs are available in a range of color
temperatures, and as a result provide a range of options to increase the visual
perception of “brightness.”
