Which Car headlight bulb is brightest? `

 It introduce the car headlight history, from 1^st kerosene lamp to 2^nd Acetylene lights, from 3rd Incandescent to 4^th halogen bulb, from 5^th HID xenon lights to  6^th LED headlights, The newest 7th is laser headlight   .

  After view this article, you will know much more about car headlights.

  Nowadays, many car brands are magnified by unique headlights, such as BMW's "Angel Eye", Porsche's "Frog Eye" and Audi's "Matrix Headlamps." So how do these lights turn? Now HCcarlights talk about the change of car headlights.

 

  After the creation of the first car from the “Father of the Car” by Carl Bentz, people’s lives have undergone earth-shaking changes. In the course of a hundred years of development, the crafts and materials have been constantly upgraded, and the car lighting is constantly being replaced.

How does the car lighting system change from a "winking eye" to a "clairless eye”? How it changed over the past 100 years?

The first generation: kerosene lamps, candles

 

At the end of the 19th century, the auto industry was still in its infancy, and the “car” was just a combination of the basic structures such as wheels, seats, and engines. At this time, the vehicles were on the road “the speaker basically relied on shouting, and the turn basically relied on look”.

At that time, car drivers often lost their way or crashed when they could not see the road at night, in heavy fog, in rain and snow.

So they put the kerosene lamps and candles that are commonly used in daily life into the lamp barrels and hang them on the car (this is similar to the previous carriage lamp). The earliest vehicle lighting equipment came into being.

Although the car was equipped with "car lights," the effect of kerosene lamps and candle lamps was too low. The lighting also fluctuates on bumpy road conditions. Only pedestrians can be alerted and roads cannot be lighted.

In case of special weather such as rain and snow, the driver would not be able to see it at all, and could only do a "wink-out."

The problem with kerosene and candles which need constantly replenish fuel, which reduces the convenience.

If happen accident causes the lamp break, it is very likely to cause a fire.

Second Generation: Acetylene Lights

 Acetylene lamps, commonly known as calcium carbide lamps, use the reaction of calcium carbide and water to produce acetylene, which is ignited by acetylene.

In the end of the 19th century, Edison had invented the first carbon filament incandescent lamp. However, the nature of the carbon filament is easy go fragile. it is impossible for the carbon filament incandescent lamp to be widely used in the automotive industry, and acetylene have a higher brightness. Become better choice for headlight.

  At that time, the car was equipped with an acetylene generator, which continuously thrashed during the driving process. This helped the chemical reaction of acetylene. When the vehicle was stationary, the acetylene was reduced and the brightness of the acetylene lamp was reduced due to the insufficient reaction.

  The exterior of the acetylene lamp does not have a lampshade and it is likely to be extinguished in bad weather.

In addition, when acetylene is exposed to water, there will be a large number of odorous white smoke. These toxic white smoke will cause harm to human health.

Third Generation: Incandescent lamps

After the appearance of tungsten incandescent lamps, the automotive lighting industry completely bid farewell to the "fuel."

Compared with carbon filament incandescent lamps, tungsten filament incandescent lamps are more stable and firmly, do not break off easily, and they can provide stable and high-intensity light sources for vehicles and solve the stability problem.

However, the energy conversion rate of tungsten filament lamps is very low, and most of the electrical energy is converted into thermal energy, resulting in energy waste, and long-term use will cause the lamp body temperature to be too high, which will cause failure. This lamp has a high failure rate.

 The fourth generation: Car halogen lamps

Halogen lamps are also a type of incandescent lamps and as upgraded version of incandescent lamps.

High-melting-point tungsten wire is used for the halogen lamp, and halogen elements such as iodine or bromine are injected into the lamp tube. When used, the tungsten filament sublimates at high temperatures, and the sublimated halogen element solidifies on the tungsten filament, thereby prolonging the bulb lifetime.

The biggest feature of halogen lamp is yellow light , in normal weather it is not good lighting effect, but in case of rain and fog, the dark yellow light penetrating higher,better road effect, but due to the brightness of the light Defects ,make it do not liked by car owners.

The fifth generation: HID Xenon lights

The xenon lamp adopts high-pressure xenon gas instead of the traditional tungsten wire, and the ballast will instantaneously pressurize the 12v voltage to 23000v, thereby igniting the xenon gas to discharge and generate a white arc light.

The xenon lamp in white color. Compared with the halogen lamp, the xenon lamp has higher brightness, lower power consumption, longer life, and more stable lighting effect. Therefore, the majority of car models at this stage use xenon headlamps.

When you choose xenon lamp, please don't choose the color temperature exceed 8000k or more. If the color temperature is too high, the light penetrating will be weaker. Among them, the best around 5500k, this color the same color as sunlight, and the human eye looks most comfortable and light the road clear.

The Sixth generation: car LED headlights

The brightness of a single LED element is low. To achieve the brightness level as xenon lamp, a set of LEDs is required, which has a higher cost.

The LED uses cold light source to emit light, so in energy conversion, the energy consumption is low and the power consumption is also lower.

In addition, the LED also has the advantages of fast lighting, simple structure, and more freedom of lamp models design.

Because there are many advantages of car led headlights, it is particularly favored by car owners, but led headlights generally appeared in the advanced vehicles, so the auto aftermarket led headlights are very popupar with drivers.

Seventh Generation: Laser Headlights

The use of lasers is not only in the military field, but also in the automotive lighting.

The laser headlamp firstly emits three blue lasers which from the laser emitter in the lamp group. After passing through the mirror, the laser is focused on the yellow phosphor filter to generate white light. After the white light enters the reflective bowl, it finally forms a conical beam.

The laser headlight can be said as upgraded version of LED headlamp. Compared with LED headlamp, the laser headlight occupies smaller volume and lower energy consumption, but the generated light intensity is 1000 times stronger than the LED headlight, and its road lighting effect is much more better than that car led headlight.

However, laser headlights now only available on luxury cars, and their prices are much more than led headlights for car

Therefore, we use hid xenon lights or led headlights, and its effect is sufficient to meet everyone's demand.

The end, From the kerosene lamp to the laser headlight, which car headlight bulb is brightest? what will the future headlights looks like? What will surprise us with sophisticated technology? Let us wait and see!
