LG Innotek develops brighter lighting module

SEOUL: LG Innotek, part of the LG Group, has developed "Nexlide-E", an automotive lighting module that is said to be over 60 percent brighter than its predecessor.

It is suitable for use as headlamps, stop lamps and taillights in vehicles.

The automotive lighting module is made of three parts. An LED package, which is a light source, is mounted on a thin substrate. Then, optical resin covers the package and substrate for protection. Lastly, a thin optical film is attached on top of the package to spread the light brightly and evenly.

Due to its brightness and lighting uniformity, the lighting module can replace multiple automotive lamps with different brightness standards.

This can improve space efficiency and allow more design variations of a vehicle's lamps.

The maximum brightness of the Nexlide-E has been raised from 80 cd (candela, the unit of brightness) to 130 cd, making it 63% brighter than the previous product. This satisfies the brightness standard of taillights, turn signals, and stop lamps.

The stop lamps have the most strict brightness standard. In Europe and North America, they are required to be 110 cd or higher. This is because stop lamps must be recognisable in any circumstances for driving safety.

The Nexlide-E is also power efficient, particularly important for electric and hydrogen vehicles in increasing their mileage range.

To do so, the company has been active in promotions targeting global car makers in the US, Japan, Europe and South Korea.

The first vehicle equipped with the Nexlide-E is expected to be mass-produced in the latter half of this year.
