Development Trend of Automotive LED

According to the latest report from LEDinside, a division of the market research firm TrendForce, 2018 Chinese Automotive Lighting Market Report- Passenger Car and Logistics Car Market Analysis, the market value of automotive headlamp LED in China is expected to reach US$1.21 billion in 2022, the highest among major automotive applications.

In terms of headlamp products, luminous density is one of the important indexes when choosing LED. As for the luminous flux of four-chip automotive headlight LED, products from OSRAM and Nichia could achieve 1200lm, which is above 215 lm/mm2 when converting into luminous density. The larger the luminous density, the stronger the brightness. In terms of optical design, the maximum brightness of module center is the highest. This way, it is easier to increase the optical efficiency of module. Moreover, diversity of head lamp LED market is increasing, multiple manufacturers have launched single-chip LEDs used in low beam.

As for matrix head lamp, the light source is required to be equipped with features including higher extraction efficiency of LED luminous flux, higher general efficiency of optical system, better optical uniformity, simpler and more flexible optical structure design, etc. Furthermore, only with smart control system can it show its best performance.

Development Trend of Automotive Driver IC

In terms of automotive driver IC, in view of typical automotive IC driver based on single LED or multiple LEDs, one DC/DC converter is basically needed to accurately provide fixed LED current for uniform brightness and color saturation. The converter must also protect LED from the damage by substantial voltage changes during driving. The design of DC/DC converter must be optimized according to the amount and type of LED as well as its functions in various applications like headlamp, tail light, turn signal, reading light, dashboard backlight and CID.

However, driver IC affects the quality of DC/DC converter, hence automotive driver IC is different from un-automotive products in reliability, safety, EMI (electromagnetic interference), heat dissipation and cost. Due to higher requirements, the challenge of automotive driver IC is also harder. For instance, with respect to reliability, automotive driver IC should ensure system reliability rather than pursue chip reliability. Equipped driver IC with LED open/short circuit and overcurrent & overheat protection functions so as to ensure driver stability. As for safety, it’s extremely important for driver IC to require error detection in operation and the reliability of data transmission structure. In regard to EMI, as driver IC should lower the complexity of EMI solution and circuit structure also need to be simplified, driver IC with integrated multi functionality becomes a key factor.
