Since the German Volkswagen applied coolblue lighting technology to its fourth-generation Golf dashboard in 1997, interior lighting has become increasingly important for building a car brand. The introduction of various new lighting solutions has brought about changes in the interior environment of the car, especially in the interior of the car at night.
The owners of the BMW Mini and Ford Mustang have been able to change the color of the interior lighting according to their own hobbies. Some concept cars, such as Land Rover LRX and Dodge Zeo, are at the forefront, leading the transformation of future production cars in interior lighting. When the driver switches the transmission operating mode from the eco mode to the sport or daily quiet driving mode, the LRX's interior lighting system will change the color of the light from green to red or blue accordingly.
New design concept
More and more designers are beginning to provide a well-designed interior environment for vehicles, especially through a variety of new interior lighting methods to create a comfortable environment for driving at night. Designers are trying to set up lights in the legroom and door trim, set downlights on the roof, and even research the interior of the car. The Land Rover LRX is probably the most strategic car in this area. When the LRX door is opened, the carpet will shine and it will be very charming.
LEDs (light-emitting diodes) are very small in size and very cheap, only a few cents in size, but they produce very strange interior effects. For example, the Rolls-Royce Phantom Coupe's multi-dollar roof interior can produce a starry sky effect, romantic and elegant, and the interior is made up of LED lights.
Automotive manufacturers and component suppliers have come to realize the potential of lighting in automotive interior design. Among them, many design concepts come from mobile phones, consumer electronics, and even Boeing aircraft.
The lighting innovation on the LRX was designed by Land Rover engineers, not from suppliers. Similarly, BMW developed the interior ambience light system for its Mini range. For most Mini owners, the variable atmosphere lights have become the biggest selling point of the Mini. The system allows the ambient light to change in a cool to warm spectrum change. Blue is the coldest shade, and pink is usually what young girls like.
The most positive feedback for this variable interior ambience light comes from children. Because they usually sit in the back of the vehicle, they can fully feel the change of the color of the atmosphere from the door to the B-pillar.
The jaguar designed a phosphor blue interior lighting system on its new XF. The switches and controls on the console stand out with a slight blue illumination. The designer said that this was inspired by the Motorola Razr phone keyboard. The jaguar and some of its competitors, as well as a variety of different lighting solutions, such as when the driver and passengers open the door or get on the car, the system will express greetings to people through the change of the lights inside the car.
Supplier's technological innovation
For the new demand for automotive interior design, major lighting products suppliers around the world, such as Automotive Lighting, Sidler Automotive, CML Innovative Technologies, 3M and Hella, are constantly developing new technologies and applications.
3M, which mainly provides adhesives and tape products, is a new entrant in the field of automotive lighting. It hopes to bring technology already used in other fields to interior lighting. Some new systems of the company will be Used in a new car in Europe. These LED suppliers and new lighting technology suppliers are leading the revolution in automotive interior lighting and giving designers more design space.
Currently, interior lighting is moving in the direction of indirect lighting, and the lines of light on the door panels and dashboard are mounted by a small LED in a rigid molded light guide. Today, suppliers can already make flexible light pipes.
Hella is a big brand in the field of lighting and the first supplier to introduce the concept of interior atmosphere lighting. Hella believes that for interior lighting, the challenge for the future is not to increase the lighting, but to ensure that the interior environment is consistent with the actual operation and use of the vehicle. This also puts more demands on suppliers, such as lighting design must be involved in the early design of the vehicle, in addition, day and night lighting style must be coordinated.
Research shows that different consumer groups have very different preferences for color, and women are usually more sensitive to color.
For suppliers, it is not difficult to produce any color lighting system, but the key is whether the driver will choose different interior lighting colors during each day of driving. Usually, consumers are very enthusiastic at first, but they tend to lose interest when they are long. This requires more market research by OEMs and lighting suppliers.
Future trends in interior lighting
LEDs, with low power consumption and 20,000 hours of service life, will soon replace traditional incandescent bulbs, giving designers more design space. Multi-color interior lighting will be used in future models. The brand will be linked to color and interior lighting.
3M and partner Visteon are conducting research on light strings and flat light sheets.
Citroen has used HELLA's non-touch door storage box lighting on its Grand Picasso. Sidler's products used on the Jaguar XF also use a similar sensing system.
Rolls-Royce designed the star-shaped roof interior on its Phantom, hand-built by workers at the BMW Dingolfing factory. The system is controlled by 1600 fibers to control the star pattern of the roof, and the pattern is random. The owner can have his own star logo. For example, a Japanese car owner puts his company's logo in a star pattern.
Film capacitors are electrical capacitors with an insulating plastic film as the dielectric, sometimes combined with paper as carrier of the electrodes. These plastic films are sometimes metalized and are available in the market under the name metalized film capacitor,these capacitors are sometimes also called plastic capacitors.
