Lighting system

A lighting system (1) comprising:

• an illuminant (4) configured to produce and emit light along a main emission direction (x);
• a light guiding body (2), which is associated with the illuminant (4), wherein the light guiding body (2) has an end section (2a) with a light entry surface (5a), wherein light from the illuminant (4) can enter the light guiding body (2) via the light entry surface (5a), wherein an outer surface (5b) of the light guiding body (2) delimiting the light guiding body (2) extends away from the light entry surface (5a) along a longitudinal extension (L) of the light guiding body (2), wherein the light guiding body (2), has a light exit section (5c), via which light that has entered exits the light guiding body (2);
• and
• a holding device (3), which is designed to hold the illuminant (4) and the light guiding body (2) relative to one another and seal the end section (2a) and the illuminant (4), wherein the holding device (3) comprises a rear side (3R) and a front side (3V) facing away from the rear side (3R), wherein a first receiving section (3a) is formed on the rear side (3R) on which the illuminant (4) is received, wherein a second receiving section (3b) is formed on the front side (3V) on which the light guiding body (2) is received, wherein the first receiving section (3a) and the second receiving section (3b) are designed in such a way that light emitted by the illuminant (4) received on the first receiving section (3a) is emitted onto the light entry surface (5a) of the light guiding body (2) received on the second receiving section (3b);
• wherein the second receiving section (3b) has a holding element (6) with a shape corresponding to the light guiding body (2), wherein the holding element (6) has a longitudinal extent (6L), which extends away from the front side (3V) of the holding device (3) and ends in an insertion opening (6a) of the holding element (6), wherein the longitudinal extent (6L) of the holding element (6) is shorter than the longitudinal extension (L) of the light guiding body (2), wherein in order to receive the light guiding body (2) on the second receiving section (3b), the end section (2a) is configured to be inserted into the insertion opening (6a) of the holding element (6) along an insertion direction oriented along the main emission direction (x), wherein the holding device (3) comprises a blocking means which blocks insertion of the light guiding element (2) along the insertion direction beyond an end position, wherein, in an inserted state, the holding element (6) encases a section of the light guiding body (2) on the periphery at least in sections, wherein a section of the outer surface (5b) of the light guiding body (2) encased by the holding element (6) defines a holding section (2b) of the light guiding body (2) on which an inner surface (6b) of the holding element (6) is opposite the outer surface (5b) of the light guiding body (2), wherein, in the inserted state, the light exit section (5c) is arranged on a side of the insertion opening (6a) facing away from the illuminant (4), and
• wherein the holding element (6) is a single structural body that also serves as a sealing element, which tapers along the longitudinal extent (6L) towards the insertion opening (6a) in such a way that the inner surface (6b) of the holding element (6) facing the holding section (2b) of the light guiding body (2) makes sealing contact with the outer surface (5b) of the holding section (2b), wherein the sealing contact prevents particles and/or fluids from penetrating through the insertion opening (6a) from the front side (3V) of the holding device (3) to the rear side (3R) of the holding device (3).
