The difference that defines a premium in-car experience

The Volvo EX90 features SunLike, a natural light spectrum technology developed by Seoul Semiconductor.

Unlike conventional LEDs, SunLike is based on opto-semiconductor technology, reproducing light close to natural sunlight.
It is not just lighting—it is a technology that designs the in-car experience.

Why lighting matters more than ever

As electric vehicles and autonomous driving evolve,
cars are no longer just transportation—they are becoming living spaces.

Interior experience is now a key competitive factor,
and at the center of it is light quality.

Lighting directly impacts:

• Visual comfort
• Color accuracy
• Human circadian rhythm

In short, the type of light defines the quality of experience.

SunLike vs Conventional LED

Conventional LEDs are designed primarily for brightness and energy efficiency.
SunLike, however, focuses on reproducing the natural light spectrum.

Key differences:

• Conventional LED: limited spectrum / partial color rendering / higher eye fatigue / function-oriented
• SunLike: sunlight-like spectrum / natural color rendering / reduced eye strain / human-centric experience

This difference goes beyond technology—it transforms how users feel and perceive the environment.

Why natural light matters

Not all light affects humans in the same way.

Light closer to natural sunlight provides a more comfortable and healthier environment.

Seoul Semiconductor, through research collaborations with
Harvard Medical School,
University of Basel, and
Seoul National University,
has demonstrated the benefits of natural spectrum lighting:

• Potential support for myopia improvement
• Better sleep quality (melatonin regulation)
• Improved memory and concentration
• Natural color reproduction

Lighting is no longer just an environmental factor—
it is evolving into human-centric technology.

Why Volvo chose this technology

In premium electric vehicles,
the key is not just performance—but the completeness of experience.

The Volvo EX90 adopts SunLike to enhance interior quality:

• Accurate representation of materials and colors
• Natural and comfortable cabin environment
• Reduced fatigue during long drives

Lighting is no longer a supporting feature—
it is a core element of vehicle UX.

From lighting to opto-semiconductor technology

SunLike represents a shift beyond traditional LED—
it is based on opto-semiconductor technology.

This marks a transition where lighting is no longer a component,
but a technology that designs human experience.

Applications are expanding across:

• Healthcare
• Education
• Museums and cultural spaces
• Mobility
  
  
  

The new standard of light

The automotive industry is shifting
from performance-driven to experience-driven.

At the center of this shift is light.

Not just brightness—but how close it is to natural light.

The future of automotive lighting is moving toward natural light.
