LG Innotek, the cutting-edge materials and components manufacturer and an affiliate of the LG group, has developed ‘Nexlide-E,’ an automotive lighting module that produces bright and uniform light.
The new lighting module is made of three parts. An LED package, which is a light source, is mounted on a thin substrate. An optical resin covers the package and substrate for protection. Lastly, a thin optical film (0.2mm thickness) is attached on top of the package to spread the light brightly and evenly. The module can be used as taillights, stop lamps, and headlights.
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. For instance, the stop lamps have the most strict brightness standard. In Europe and North America, the stop lamps should have 110 cd or higher as they must be recognisable in any circumstances for driving safety.
The company applied a high-performance and high-reliability optical film to improve the lighting performance. Its micropatterning technique was used in the film to give a variety of lighting effects.
According to the company, this lighting module can replace multiple automotive lamps with different brightness standards into one module due to its brightness. It can improve space efficiency and allow more design variations of a vehicle’s lamps.
The Nexlide-E is also power efficient because the module is bright enough with a small amount of electricity. This is particularly important for electric and hydrogen vehicles in increasing their mileage range (corresponding to fuel economy in conventional vehicles).
Also, car manufacturers can replace different lightings of a vehicle such as a taillight and stop lamp into one lighting module using the Nexlide-E. The product’s high brightness makes this possible by satisfying the different brightness levels of taillights, stop lamps and turn signals.
As the number of lighting modules used decreases, car manufacturers can design slimmer and more compact lamps and increase space efficiency by widening the trunk and such as a half-mirror that assists 3D effects within a lamp.
Insoo Ryu, VP & Head of the Automotive Components & Electronics Business Division, said, “The Nexlide-E is an innovative product that satisfies the customer needs for distinctive automotive lighting designs that give characters to vehicles. With the Nexlide brand, LG Innotek will continue to deliver a safe and enjoyable driving experience with the automotive light source solution service.”
