    Abstract: Various embodiments may relate to a fault detection device for streetlamp lighting system. The streetlamp lighting system includes multiple load groups which are powered by a power cable. The fault detection device includes a master detection control unit and load detection control units configured for respective load groups, wherein the master detection control unit determines, according to a first fault feedback signal provided by respective load detection control unit, whether the load group corresponding to the load detection control unit is failed, while the streetlamp lighting system is in a first state, and the master detection control unit determines, according to a physical quantity detected on the power cable, whether the power cable is failed, while the streetlamp lighting system is in a second state. In addition, various embodiments further relate to a method of controlling the fault detection device.

    Abstract: An LED module includes a carrier plate having an arrangement face and a wall on the upper side of the plate, the wall running peripherally around the arrangement face and being raised upwards with respect to said arrangement face; an LED arranged on the face; a contact element, to which the LED is connected; and an at least partially transparent potted body covering the arrangement face and the LED towards the top and laterally adjoins an inner face of the wall. The wall is formed monolithically with the remaining carrier plate and is interrupted over its periphery, and the potted body does not adjoin the inner wall face of the wall. The contact element extends away from the arrangement face along the upper side of the carrier plate in the interruption region so that electrical contact can be made with the LED via the contact element from outside the body.

    Abstract: A lighting device comprises a housing carrying a linear array of light radiation sources and one or more elongated diffusive screens arranged facing the array of light sources so as to be passed through by the light radiation. The screen or screens have a pattern of geometric features for producing a radiation pattern of the light radiation emitted by the lighting device as a result of passing through the diffusive screen or screens. By replacing the diffusive screen or screens with screens which have a different pattern of geometric features it is possible to vary the radiation pattern of the light radiation emitted by the lighting device.
