How to choose street light fixture – ultimate guide

Street Light fixtures are ideal for outdoor areas including streets, roadways, parking lots, and pedestrian areas. Well-designed LED outdoor fixtures can provide the required surface illuminance using less energy and with improved uniformity.These Street Light fixture also have significantly longer life and offer better lumen maintenance, energy efficiency, durability, color quality, light distribution, thermal management, and low cost.

When selecting an LED Area Light, you will want to consider the following options:

Mounts

LED Area Lights are available in different mounts such as pole mounted fixtures, slipfitter and trunnion mount models, knuckle pole and wall mounts.  LED Area Lights  also fit into commercial fixtures and shoebox fixtures which feature multiple mounting options, and a  heavy duty slim design.

Lumens

With new light bulbs, shopping by lumens is more important than shopping by watts when choosing which energy-efficient bulb to purchase. While wattage measures the amount of energy required to light products, lumens measure the amount of light produced.

This means that the more lumens the product has, the brighter the light source is. Instead of buying products based on how much energy they consume (watts), consumers should consider how much light they give us (lumens).

Wattage

Wattage is the measure of the bulb’s energy consumption – not how much light it puts out. Energy-efficient bulbs use fewer watts to give off the same amount of brightness (lumens). Because of this, LEDs (which have typically low wattages when compared with lumens) not only help reduce energy usage but also lower electric bills.

Color Temperature

Color temperature refers to the color appearance of the light that comes from a light source. It’s an important performance characteristic to asses when evaluating bulbs.

Because the color temperature creates the mood of the space you are lighting ,and can thus influence buying behavior or work performance. The apparent color of a light source is measured in Kelvin. The higher the Kelvin temperature, the whiter the light.  Street light fixture structure qualification like if it is strong enough above IK06 or IK08, IP level like above IP65.

Color Temperature of  Street Light ?

The choice of light temperature depends on what effect we want to achieve. For highways, yellow light should be preferred; in conditions of poor visibility such as fog or blizzard, 2700-3500K temperatures will provide better coverage. Led city light for the parking areas could be cool white color 5000-6000K, due to the fact that it provides better feeling of security to pedestrians than warm colors.

What Voltage to Choose?

The choice of power for the street lamp depends on the size of the road, which we are selecting illumination for. The larger the distance between poles and the width of the roadway, the more powerful the lamps must be.

1. For led highway lighting, poles are usually located at lengthier distances from each other and lamps are set farther away as well. In this case, we need high power led street light from 150 to 600 watts.

2. For the illumination of minor roads, less powerful lamps can be installed. The suitable road light for this situation should be from 70 to 150 watts.

3. For illumination of sidewalks, parks, bicycle paths, etc, the street light fixture could consist in a low-power lamp, from 30 to 80 watts.

The LEDs act as a light source. They are non-toxic, and therefore do not require special recycling. LED lamps light up instantly, don’t need to warm-up (as HPS lamps) and do not consume high inrush currents. Driver LED lamp has a high efficiency and does not generate noise during operation.

They have many advantages over conventional lamps as longer life span, instant readiness for operation, lack of body heating, energy saving and many others. Unlike fluorescent lamps. LEDs do not emit harmful UV-rays. That destroy the materials and coloring of paint, which makes them an ideal lighting solution.

Now we can see that LED lights have more advantages when compared to other technologies. They are more efficient, require no maintenance, and are environmentally safe. Many countries have already completely switched to LED lighting. Further we consider this type of lamps for road applications.

When choosing led road lamp, one should pay attention to the different characteristics such as energy efficiency, power, security, etc. Let’s have a look at main parameters we need to consider.

CONCLUSION

Apart from the basic features for a led street light such as lumen, driver, led chips, IK, IP etc. The most important is that if the  photometric file is properly designed. Before you consider to purchase a street light fixture. Firstly, it is very necessary to know about your roadway situation and classification. and secondly, the necessary action to take before the purchase is to ask your supplier for  the tested photometric file to have the basic evaluation.  If it is suitable for your roadway situation.
