Improved replacement system for an optical component of a lighting device

An optical component holder for assembling a lighting device, said optical component holder comprising:

• a central portion and an edge portion, wherein said edge portion delimits said central portion, and wherein said central portion and said edge portion extend substantially in a longitudinal plane;
• at least one flexible flap being attached to said edge portion of said optical component holder and extending substantially in a transversal plane being substantially perpendicular to said longitudinal plane, said at least one flexible flap comprising a locking snap-fit arrangement, wherein said locking snap-fit arrangement comprises a lower portion being adjacent to said edge portion of said optical component holder, an upper portion arranged at a distance from said lower portion in said transversal plane, said locking snap-fit arrangement further comprising a releasing portion;
• a housing connection being arranged for attaching said optical component holder to said lighting device, said housing connection being attached to said edge portion of said optical component holder and extending in said transversal plane and comprising a locking element;
• a releasing element accompanied with one or more ratchet surfaces that are facing away from said central portion of said optical component holder for releasing said locking element;
• wherein at least one flexible flap has a lower portion of said locking snap-fit arrangement that comprises a contact surface facing said edge portion, said lower portion of said locking snap-fit arrangement further comprising a wedge element extending substantially parallelly to said longitudinal plane and facing said central portion of said optical component holder, said lower portion of said locking snap-fit arrangement being movable between a locked position and an unlocked position in said longitudinal plane, said lower portion of said locking snap-fit arrangement having a transversal cross-section being substantially parallel to said transversal plane,
• wherein said transversal cross-section of said lower portion of said locking snap-fit arrangement is substantially U-shaped, and
• wherein between said contact surface and said longitudinal plane, a contact angle is created that is an acute angle.
