Concept Behind the Lighting Technology:

The true power of the Lighting Industry reveals itself when the sun disappears behind the horizon. With the world’s fastest-growing companies’ demand for innovation and technology increasing at night, modern lighting systems need to ensure optimal lighting.

Strong & Intelligent Lighting is very important because about 30% of all accidents involving personal injury occur at night, and accident severity is much higher than during the day. Moreover, as the number of daylight hours shrinks at the end of the year, these incidents become even worse.

Headlights are a major factor in providing a safe environment for night driving.

Early generations had Candles or Oil-based Light then slowly halogen headlamps that became brighter and brighter. These were followed by first Xenon Headlamps, then LED tail lamps, LED daytime running lights, and now it’s LED headlamps and probably Laser Lamp in the future.

Lighting Technology revolution is only based on Safety followed by Intelligence

Future Lighting Technology

Light-source tech will keep advancing, but the major area of change in headlamps will be the control of the light beam. So, industry giants have started working on various advanced technologies – which are sometimes successfully implemented on some Higher-end Vehicle.

Example: Volkswagen partnered with Hella, developed the IQ. LIGHT -LED Matrix beam headlamps.

The heart of the Matrix LED headlights is the mechanic free glare-free high beam. This allows the driver to travel in his vehicle with a permanent high beam, without risk of dazzling oncoming traffic or any preceding vehicle. A camera detects oncoming and preceding traffic and shuts down or dims individual LEDs.

One of the first light-based assistance systems was the dynamic bend lighting function. Also known as Adaptive Front Light System (AFS), this is incorporated into vehicle headlamps. This system uses both the steering angle and the vehicle speed as parameters for illuminating the road. Based on this internal information, a cylinder creates various types of light distribution, including town light, country light, adverse weather, and motorway light.

The development of the adaptive cut-off line (aCOL) goes one step further. This feature also utilizes data gathered from the vehicle’s surroundings to generate the light distribution. A camera detects oncoming traffic and the cars ahead, and a stepper motor turns the cylinder to the required position within milliseconds. It creates a glare-free high beam. Currently-used targeted spotlighting functions allow specific illumination of certain types of objects, such as children playing at the edge of the road.

Similarly, Valeo, ZKW and a Japanese MNC Koito also invented and implemented the same functional Head Light using different methods and Technology.

Valeo and Koito used ADB Technology in Head Light to prevent traffic accidents at night – it’s “Blade-Scan ADB” an array that controls light distribution by turning on/off each LED individually. It emits LED light to two fast revolving blade mirrors (reflectors) and lights the way forward by using the residual image effect.

By turning on/off 12 LEDs in line with the rotation of the blade mirrors the system lights vicinity of oncoming vehicles and vehicles ahead or an area between them and helps drive to early detect crossing pedestrians & avoiding glare thus contributes to reducing traffic accident. The function also considers the rear lamps of vehicles driving in the same lane. Those functions are grouped together under the name BE AMATIC.

In addition to this, Koito is integrating LiDAR (Light Detection and Ranging) sensors into headlamps and rear combination lamps. Located on four edges of the vehicle, these lamps help sensors to improvingly detect pedestrians and traffic, covering 360 degrees around the vehicle. They serve to avoid car accidents under various driving conditions.

And ZKW, using target lighting (rotating lens) and night surveillance system, captures all moving objects in the field of view, even if the headlights are not yet illuminated. The driver can immediately identify the detected dangerous object. In this way, the driver can save valuable reaction time to prevent pedestrian collisions or road kills.

Along with Safe and Smart Lighting Technology, businesses think about Slim and Stylish Head Lamp too. So ZKW invented Stripe-Z Technology.

Humans instinctively recognize and interpret faces. Therefore, the face design of vehicles is also becoming more and more important. The headlight of a car expresses the character like a human eye.

The size of the Stripe-Z lighting module for the main headlight is much smaller than conventional devices, with the same lighting performance. The height of the viewable lens is only 22-30 mm.

Despite its small size, Stripe-Z clearly demonstrates a capable performance. In addition to the optical advantages, the advantage of the Stripe-Z family is that it requires less space for installation, creating additional clearance in the headlight housing, allowing for the integration of the housing sensor.

Along with Head Lamp, there’s Revolution in Tail Lamps & Indicator Lamps too.

New systems such as matrix tail-light clusters will also revolutionize tail-lights. Matrix tail-light clusters will allow warnings to be incorporated into the taillights.

The indicator lamp, with bright orange arrows on the road, extends into space an object is moving towards, which eliminates the blind spot.

“Optical Lane Assist” paints the road ahead with lines showing the width and trajectory of your car, bending as the steering wheel turns.

Importance of Laser Light

Laser light is much smaller than LED lights and saves energy. The laser light, which is only a few thousandths of a millimeter in size, produces light that is almost point-shaped. It also boasts a much higher brightness than LEDs. The use of laser headlights ensures more active safety when driving at night.

Future Thoughts

In the future, some giants are planning to promote miniature lasers, Micro Electrical Mechanical Systems (MEMS), organic light emitting diodes (OLED), and special LED configurations.

(Microelectromechanical systems (MEMS), also written as micro-electro-mechanical systems (or microelectronic and microelectromechanical systems) and the related micromechatronics and microsystems constitute the technology of microscopic devices, particularly those with moving parts. They merge at the nanoscale into nanoelectromechanical systems (NEMS) and nanotechnology. MEMS are also referred to as micromachines in Japan and microsystem technology (MST) in Europe)
