Abstract

A lighting arrangement and a method for manufacturing the lighting arrangement are provided. The lighting arrangement has a holder to carry an optical element above a LED lighting element. The holder has an optical sub-holder and a connecting sub-holder connecting the optical sub-holder with a support member, where the LED lighting element is arranged on. The optical sub-holder has at least one stress release element dividing the optical sub-holder in one or more outer parts connected to the connecting sub-holder and a main part carrying the optical element, where a mechanical connection between the main part and the one or more outer parts is weakened by the stress release element extending through the optical sub-holder to enable the one or more outer parts to deform freely in case of thermal stress while maintaining the main part closer to the desired position compared to the one or more outer parts.
