In the past few decades we have witnessed a remarkable growth in lighting applications. Light has emerged to places where we did not use to see it, for example stair railings illumination, ambient lighting in home appliances and controllable mood light installations in urban environments. These new places and usages for light give possibilities to create delighting user experiences, whether it be creating for example a sophisticated, subtle ambient lighting in a car, or a novel way to guide the HMI user with light. The reason behind this growth is the evolution of LED (Light Emitting Diode) light source, which is known for its good light output characteristics, small size and efficiency. Small size and efficient light output enable high freedom in LED placement with minimal thermal management.


Conventional lighting structure has mechanical lightguides and extensive amount of supporting assemblies and fixing mechanisms.


In conventional illumination design, while being highly flexible in terms of design, the LED placement still has its restrictions: it always needs a printed circuit board (PCB), which again needs powering, fastening features to the other mechanics etc. This approach is attractive when the product design enables enough room for such features. Then again, the light has to be guided to the illuminated area with mechanical light guides and light properties need to be managed.


In IMSE, the LEDs are surface-mounted onto a plastic substrate. This structure is then covered with injection molding resin. Components are thus inside the resin which forms the light guide. Over-molding forms a solid part where all the functions are integrated. This means that the LEDs can be placed inside the part wherever they are needed, i.e. LED placement is purely UX-driven.

Thus we can say that IMSE technology is revolutionizing the lighting applications by enabling truly thin and weight-saving parts with design freedom, new illumination features and minimized assembly. These benefits of IMSE technology are attractive across the industries from automotive to home appliances where innovative illumination solutions are in high demand for design differentiation and user experience.


We welcome you to join TactoTek IMSE Illumination Design webinar on October 7th to learn more about the illumination applications and the potential IMSE has in store. The webinar is co-hosted by LightWorks, an established and globally operating optics and lighting solutions provider and developer. We are hosting two sessions for you to choose from.
