Reducing thermal sensitivity of a lighting arrangement

A lighting arrangement comprising:

• at least one light emitting diode (LED) lighting element arranged on a support member;
• an optical element arranged spaced from the LED lighting element in a first direction;
• and
• a holder to hold the optical element in a position relative to the LED lighting element, the holder comprising at least a first holding portion extending from the support member into the first direction and a second holding portion connected to the optical element arranged such that at least a part of the second holding portion extends into the first direction,
• wherein the second holding portion is spaced from the first holding portion in a direction traverse to the first direction,
• wherein the first holding portion and the second holding portion are connected by a first connecting portion arranged to form an angle with both the first holding portion and the second holding portion,
• wherein the first connecting portion is a plane wall element having a greater thickness than the first holding portion and the second holding portion, and
• wherein the optical element is one piece with the first holding portion and the second holding portion.
