Can Light-Emitting Diode (LED) serve as efficient headlights in your car?
Why should you replace the traditional halogen or filament bulbs with it?
LED lights are illuminated all around us – from traffic signals to display boards to communication panels.
Car manufacturing companies are including it in most of their new models. If you do not own a recently released car, your car’s headlights are most likely not LED. But, there are some significant benefits you can derive from making this switch.
Here is a list of reasons for shifting to LED headlights for your car:
- Low power consumption & environment-friendly
Halogen bulbs use a tungsten filament with argon and nitrogen gas and produce substantial infrared (IR) and ultraviolet (UV) radiation. The luminous efficiency of halogen bulbs is less than 5%, which reflects that they draw a lot of power to emit a certain amount of light.
LED headlights work by passing electrons through a semiconductor, which releases photons to emit light. There is no toxic gas involved, and its luminous efficiency is at least ten times more than halogen bulbs. LED headlights draw a fraction of the power drawn by halogen bulbs to emit the same amount of light. It produces no IR or UV radiation.
Being a type of incandescent light bulb, halogen headlights emit light through extreme heat generation. The excessive amount of heat in a halogen bulb makes it very hot to the touch. It requires changing if the filament or halogen gas burns out due to the heat.
LED headlights generate some heat, but it is negligible relative to halogen bulbs. It works by creating photons, primarily the light we see through naked human eyes, so there is no direct heating process. The chance of parts of it burning out is eliminated, and it is not nearly as hot to the touch.
- Lasts longer
Halogen or incandescent bulbs have a short lifespan due to the lower luminous efficiency, high power consumption, and excessive heating to emit light. Your car headlights may dim or stop working altogether sooner than you would like.
LED lasts much longer than halogen or incandescent bulbs primarily due to the lower operating temperature. Unlike halogen bulbs, it does not require immense heat to function, and that increases its lifespan significantly.
Halogen bulb based headlights are bright enough to illuminate the road for about one hundred meters on average. The lumen output and luminous efficiency reflect the brightness and power consumption needed to generate that brightness respectively.
In the case of LED headlights, the same lumen output as halogen headlights is generated by drawing lesser electrical power. Or the same electrical energy can be used to create greater lumen output. It is significantly more efficient and much brighter.
- Cost-effective in the long run
Halogen bulb based headlights are very reasonable and operate smoothly, but its operational and environmental efficiency is not high. It requires a lot of electrical draw from your car battery and is not energy efficient.
Although the initial cost of purchasing LED headlights is more, it will not require quick replacements. It provides significant energy savings over its extended life, which makes it a better prospect financially for you in the long run.
- Flexibility and faster switching time
When it comes to car headlights, a whiter beam of emitted light is preferred as it is more similar to natural daylight and offers better visibility. A halogen bulb needs to burn hotter to emit a whiter light, and it is not functional in cold weather conditions.
LED headlights are much more flexible as the color of the emitted light can be altered merely by changing some physical characteristics of the semiconductor. It can work well in cold weather conditions and has a negligible switching time, making it a superior choice.
Throwing some light
A LED headlight is more efficient than other headlights – higher luminous efficiency and lumen output with lower wattage consumption. It is environment-friendly – energy efficient and produces negligible UV or IR radiation. It is brighter and cooler than halogen or incandescent bulb headlights. And it provides at least ten times the longevity as other types of headlamps.
The only concern for LED headlights is the initial cost and complex set up. It requires additional heat sinks and cooling systems or fans, and if you are replacing your old headlight with it, you may need an LED conversion kit. The various benefits and long-run energy savings undoubtedly make it worth the initial cost and set up.
