一,The difference in energy efficiency between LED Street Light and regular light bulbs
The major reason LED Street Light can save energy is that they use multiple ways to make light. Incandescent light bulbs work by passing current through a filament, which makes it hot. Most of the electrical energy is turned into heat energy, and just a little amount is turned into visible light.
Research data from LED technology companies like Cree Inc. show that LED lights are more better at converting light into electricity than other types of lighting. Usually:
Incandescent lights use roughly 10 to 15 lumens per watt of power.
LED Street Light can be more than 100 lumens per watt efficient.
Energy efficiency went up by 80% to 90%.
In other words, LED lights use a lot less electricity than regular light bulbs while the brightness is the same.
二, How much less electricity does LED Street Light use than incandescent light
As an example of how to do the math, let's say we need common lighting
An incandescent light bulb that uses 60 watts is about the same as an LED light bulb that uses 8 to 10 watts.
An incandescent lamp with 100W is about the same as an LED lamp with 12W to 18W.
An incandescent bulb with 40 watts is about the same as an LED lamp with 5 watts.
LED Street Light use roughly 85% less electricity than incandescent bulbs, which is a lot. The savings on your electric cost are considerable if you utilize it for a long time.
For instance, a 60W incandescent bulb that is used for 5 hours a day uses roughly 109.5 kWh of electricity per year. In comparison, a 10W LED bulb uses just about 18 kWh of electricity per year.
三, How much more energy-efficient are LED Street Light than fluorescent lighting
LED lighting also save a lot of energy compared to fluorescent lamps.
Fluorescent lights that are not modern lose ballast and light quickly. LED Street Light use DC drive technology to cut down on energy conversion losses.
Here is the general comparison data:
Fluorescent bulbs have energy-saving benefits: a benchmark
LED lights can save 20% to 30% more electricity.
The lifespan can be more than doubled.
四,Things that affect how well LED Street Light save energy
LED lights save energy on their own, although the actual energy-saving effect depends on a number of things:
Power quality for driving
Driving power supplies that aren't very good can lower the efficiency of energy conversion and potentially speed up the decay of light.
design for heat
In places with extreme temperatures, LED chips will not work as well. If the heat dissipation isn't good, the brightness might go down, but the power use won't go down much.
Where it is used
Lighting stability can be affected by long-term exposure to high temperatures, excessive humidity, or dust.
Differences in the quality of the product
variable brands of LED lights on the market have quite variable levels of energy efficiency. It is recommended to choose products with mature technology.
五, How much money can you save by using LED lights for a long time
LED lights cost more per unit than regular light bulbs, but they are cheaper in the long run.
Let's say:
LED light lifespan: more than 20,000 hours
The life of an incandescent light bulb is about 1000 hours.
If you use it for 6 hours a day, it will last:
You might have to change incandescent bulbs 10 to 15 times.
