BMW Develops Laser Light for Headlights
At the Light Emitting Diode (LEDs) are used in a small proportion of new luxury cars for headlights, lighting technology for motor vehicles are considered to be superior to it, was ready also introduced. Lighting or lighting technology is considered to be very great car it is a laser beam.
Car companies that claim to have developed berhasilkan headlights type of laser is Bayerische Motoren Werke (BMW). And now BMW still boasts LED technology headlamps used on Series-6 with features, namely "Anti-Dazzle High Beam Assistan" (anti-glare) and "Dynamic Light Spot", the lights can be automatically marked Penjalan feet appropriately and help direct the driver.
For i8
BMW said the technology as a laser beam headlamps can be exploited in the next few years. Even to say, one of the sub-model BMW brand, the i8 to be produced in 2014 is estimated to be able to use headlights with teknologio this laser.
Described, the laser light can meet all requirements and facility functions headlights a more secure and comfortable plus energy efficiency is much better.
By definition, the laser light is very different from the sun and also from various types of artificial or artificial light that is commonly used today. Laser light is monochromatic type, which means all the light waves of equal length. In addition, also known as the light source "coherent" which means a constant phase difference wave.
As a result, the laser produces a beam of parallel adjacent to the intensity of a thousand times more powerful than conventional LED lights. Characteristics like these can add new features when used for the headlights. In addition, with a very high light efficiency, when used for the headlights, the energy required is only half of the LED lights. Means of laser light is very energy efficient!
Safe!
The intensity of the laser beam for the headlights, is said by the insinyyr BMW will not pose a risk to living beings, namely humans and animals. Because the laser beam is fired directly into the street or in the future. In the bulb, the laser beam first amended in accordance with the needs of the traffic light on the highway. The resulting light said to be very bright, white and pleasing to the eye.
Further, a safe laser illumination technology is now used on a variety of products without the knowledge of the user. Therefore, this laser light will not cause problems when later used.
Diode 10 micro-
The important implication is the size diodenya laser technology. The length is only 10mikro (μm), which means it can be made up to one hundredth of times smaller than the cell size of a conventional LED lamp with a side length of one millimeter. With this addition, it allows all the light sources can be put together.
With regard to the size, the BMW engineers have not had a radical plan to reduce the size of the headlamps, although it is theoretically possible. BMW is most likely to be appropriate to maintain the dimensions and surface area of conventional lamps. The goal is to maintain the appearance of the BMW line with his trademark over the years. Just described, can be reduced into the lamp or lamps may be mounted on the front part of the car body.
170 Lumen per Watt
Another advantage of laser light is high efficiency. According to BMW, based on a single statistic, LED lighting produces only 100 lumens per Watt, while the laser light 170 lumens. The last factor is what makes BMW very bergairahkan use headlights with laser technology.
To be used for daily necessities and also safe for living things, before the beam from the laser diode is released to the streets of small, light bluish-biruannya changed first. To that end, in the gas-filled bulb fluorescent phosophor. The result, white light dihasilskan be clean, bright and not hurt the eyes.
Planned, in the future, BMW will use a laser headlamps with features such as now, namely "Adaptive Headlight", "Dynamic Light Spot" and "Anti-Dazzle High Beam Assist". Posts of!
