Safety-critical lightings light up vehicle aesthetics
The automotive industry is growing in different directions. Lighting is a vital component in automotive vehicles, playing an important role in automotive safety. The vehicle consists of different lights to increase visibility in darkness and bad weather along with the increase in complicity. For lighting, which is safety critical and an essential ingredient of vehicle aesthetics, enhancing the aesthetic looks to both interior and exterior parts.
The lighting system comprises lighting and signalling devices, which are placed at different locations such as front, rear, side, and interiors. Lighting provides illumination for the driver and helps other vehicle drivers and pedestrians on the road to detect the vehicle’s position, direction of movement, and size. The consumers are looking beyond incandescent lights. Preference is for high intensity discharge (HID) headlights and other 12V LED lighting solutions. Even more options and modifications are available now. There are amazing new technologies. But many of them are not genuine improvements or even street-legal.
Automotive lighting had been changing along with the vehicles until it reached the halogens through incandescent bulbs. With their increased light output halogens are the most common light source for headlights even today. They are giving way to HID (high intensity discharge) bulbs and LED (light emitting diode) lights and OELDs (organic light emitting diodes).
The major players operating in the market of global automotive lighting are Magneti Marelli (Italy), Philips Lighting NV (Netherlands), Ichikoh Industries Ltd (Japan), Hella KGaA Hueck & Co (Germany), Koito Manufacturing Co Ltd (Japan), ZKW Lichtsysteme GmbH (Wieselburg), Peterson Manufacturing company (U.S.), OSRAM GmbH (Germany), Stanley Electric Co. Ltd (Japan), and General Electric (USA).
India’s automotive lighting market is expected to garner $3.1 billion by 2022, registering a CAGR of 5.6%, says a report published by Allied Market Research. The Indian automotive lighting market has witnessed significant growth on account of increased automotive sales and economic growth. In addition, it is driven by increasing population and concerns about vehicle safety triggered by government regulations.
Growing emphasis on road safety: Rising number of road accidents during bad weather conditions and night is the prime concern among vehicle drivers. This has risen the demand for reliable and brightened automotive lights. Therefore, the growing emphasis over enhanced road safety through high-performance automotive lights has created the need to develop advanced lights providing better illumination in the darkness.
New regulations: The Indian
government has formulated various regulations regarding sufficient installation of lighting equipment in passenger vehicles. Few regulations are still in the process of being laid down to improve the safety of vehicle in bad weather conditions. The regulations regarding energyefficient vehicles support the installation of LED lights in vehicles. Thus, such regulations are expected to fuel the growth of the automotive lighting market.
Rising vehicle sales: Automobile sales has witnessed notable growth rate in India. The revival of economy has particularly supported the growth in the recent past. This growing trend is expected to continue during the forecast period with sizeable demand of passenger vehicle and two-wheelers. Automotive lighting industry, which depends on the state of automotive industry for its growth, is expected to certainly benefit from this ongoing rising vehicle sale.
LEDs to the fore
Numerous technological advancements were observed in the commercial automotive lighting down the years. Currently, the segment for LED lighting technology is gaining widespread popularity worldwide. According to a recent report published by Allied Market Research, titled, `Global LED market by type and application: Global opportunity analysis and industry forecast, 2018-24’, the global LED market was valued at $33.10 billion in 2017, and is projected to reach $96.71 Billion by 2024, registering a CAGR of 15.9% from 2018 to 2024.
LEDs are used in variety of applications. A few years ago, application of LED was limited to certain specific lighting needs and had not entered the mainstream general lighting applications. Entrance of LED in applications such as general lightings have given a strong thrust to the market. LED is expected to take over the conventional CFL and CCFL lighting market due to advanced features. Moreover, it is a costeffective solution for all lighting as well as other application purposes such as backlighting in large screen displays, automotive lighting and many others.
At present, Asia Pacific dominates the market, followed by Europe. In 2017, the U.S. is expected to remain dominant in the North America market, while China is projected to lead the overall market in Asia Pacific.
Increase in government focus on energy saving solutions, increase in utility rebates, and Growing display and large screen backlighting market are the factors that drive the market. In addition, growth of smart lighting and high efficacy LED boost the growth of the LED market. However, high initial cost restricts the growth of the market.
For automotive, LEDs are also excellent for extremely bright off-road bar lights. Their high efficiency allows them to consume significantly less power to produce the same amount of light as other sources or consume the same amount of power and produce huge amounts of light. A 100W incandescent flood light producing 1500lm could be replaced with a 13W LED bulb, or an LED bulb could consume 100W to provide over 10,000lm. Even though 100W is a reasonable amount of power
to draw from a car battery, the battery voltage is only 12V. This means the PCB supporting the LEDs in a bar light needs to be able to handle moving over 8A of current without incurring voltage drops that would cause LEDs at the extremities to dim.
Several studies ascertain that the future of automotive lighting is bright, but the immediate future is not quite as “smart” as that of other verticals because the regulations are simply not prepared to handle the newest technologies. Adaptive headlights are already rising in popularity in Europe. Regulatory agencies in India could bring this to India along with BSVI and the new road safety regulations. Adoption of LEDs are set to rise as they are becoming more affordable and get designed into vehicles from the original manufacturer, rather than only being available as an aftermarket modification.
The Munich-based Osram is launching XLS (eXchangable LED Signal), standardized LED light sources for signal light applications in the automotive industry. By combining standardized light sources and LED technology, the company will fundamentally change the automotive signal lamp sector.
