Abstract: The method includes a first step of providing a housing with a hollow protrusion. A second step provides an auxiliary element in the hollow protrusion. A third step provides a connector receptacle in connection with the auxiliary element. A fourth step inserts a matching connector in the connector receptacle in a detachable way, the matching connector further including guiding means. A fifth step places a luminous module including a module connector, the module connector being helped by the guiding means to be connected to the matching connector, to achieve an electric connection between the module connector and the matching connector. A final step moves the connector receptacle so that the matching connector exits from the connector receptacle.

Abstract: A torque limiting adjuster for adjusting the position of an adjustable part of a lighting device includes a housing, an output shaft, a driving gear, a driven gear, and a biasing element. The housing includes a main opening and a first threaded portion. The driven gear includes a gearing portion adapted to be engaged with the driving gear. The driving and driven gears are engaged by the biasing element. The output shaft has a first linear guiding portion oriented in a main direction and a second threaded portion coupled with the first threaded portion. The driven gear has a second linear guiding portion slidably coupled with the first linear guiding portion. The second linear guiding portion is configured to transmit the rotation of the driven gear to the first linear guiding portion when the driven gear rotates driven by the driven gear.
