A variable light beam is provided from a light source. The light source can be an LED light source or other source. The light source includes basic collimation optics, such as reflector or Fresnel lens, an electrically controllable LC device, such as a polydisperse LC film, in front of the incident spot light beam. Preferably the polydisperse LC film includes transparent flat uniform electrode layers. The LC device can be autonomous of the light source. The proposed solution provides a dynamically controllable, preferably polarizer-free and pixel-free, beam shape light source module including a controllable light beam control module and a light source module providing the initial light beam in a scanner light source, a camera flash, an architectural, automobile or industrial lighting device.

The laser mount arrangement can have a laser bar and a driver positioned adjacent to one another and secured against a connection face of a heat sink base. The heat sink base is connected to and forms a first electrical connection between the laser bar and the driver. A second electrical connection is also provided between the laser bar and the driver opposite the heat sink base, which can be in the form of a flexible metal sheet with a narrow upward fold. This arrangement can provide a low inductance path for the current.
