Headlamp heaters
LED headlamps are far more energy-efficient compared to their older halogen counterparts. However, their rise in popularity poses a new challenge as LEDs do not generate sufficient heat to de-ice the lens in harsh weather. With efficient and even heating, high optical performance and direct surface integration by film insert molding, Canatu LED headlamp heaters are an optimal solution that prevent headlight obstruction and mitigate safety risks.
Headlamp heaters that mitigate visibility and safety risks in any weather
Unlike their older halogen bulb counterparts, LED headlamps generate very little heat. Ice and snow can stick to the headlamp which can obstruct the view, increasing road safety risks.
Canatu CNT film heaters provides even heating throughout the headlamp, keeping the optically critical areas clear from fog, snow and ice. Canatu CNT heaters can be high pressure formed or thermoformed into any 3D shape, and injection molded inside the polycarbonate (PC) lens for robustness.
Canatu LED headlamp heater benefits:
- superior optical performance
- wire-free on optically critical areas
- fast, even and power-efficient heating
- 3D formable and in-moldable
High optical performance
Canatu LED headlamp heaters are highly transparent, wire-free, and exhibit high optical clarity with no haze or distortion. This ensures that vehicle’s headlights maintain accurate beam form to light up the road as designed.
Even and efficient heating
Temperature gradients are a common challenge caused by wire heaters, where the wires heat up faster than the surrounding surface area, causing optical distortion. Unlike metal wire heaters, Canatu LED headlamp heaters are film based, which means the entire surface is conductive. This provides simultaneous and even heating throughout the surface with minimal temperature gradient.
In-molded for robustness
Canatu headlamp heaters are built on a polycarbonate (PC) substrate. Our heater can be Film Injection Molded (FIM) during the injection molding of the lens. This integrated structure provides a very high level of reliability.

Enabling ADAS system reliability in any weather
With the rise of autonomous driving and the increased use of active safety features, there is a greater need to ensure the consistent performance of sensors, cameras and LED lights in all weather conditions.
Due to their advantageous optical and mechanical properties, Canatu LED headlamp heaters are suitable even in headlamps that have embedded camera and LiDAR systems, effectively keeping all critical sensor surfaces clear. Such heater performance can be contrasted with that of the more traditional microwires, which not only interfere with such camera and LiDAR systems, but offer less design freedom due to the limitations of visible circuits.
