The invention relates to a lighting device having a support element (2) with an elongated receiving region (3) which has a U-shaped cross-section and comprises a first limb (31) of the U, a second limb (32) of the U, and a connecting limb (33) that connects the two limbs (31, 32) of the U. The lighting device further has an LED lighting module (4) with at least one LED (5) for generating light in order to emit a light of the lighting device, said LED lighting module (4) being arranged on the support element (2) in a retained manner. The lighting device further has a contacting element (6) for supplying power to the LED lighting module (4). The connecting limb (33) has a through-opening, said contacting element (6) and LED lighting module (4) being arranged so as to be connected in an electrically conductive and reversibly releasable manner such that the electric connection passes through the through-opening. The design of the lighting device allows the conductive wires for supplying power to the LED lighting module (4) to be arranged on the connecting limb (33) side which lies opposite the at least one LED (5) of the lighting module (4). In this manner, access to the conductive wires is hindered and the lighting device is therefore particularly safe. Additionally, a particularly simple, safe, and reliable exchange of the LED lighting module (4) is made possible in this manner.
