摘要： A lighting module including a housing with a cavity enclosed with a light-emitting surface and in which an LED is mounted connectable to a power source and possibly also to a control circuit. Between the LED and the light-emitting surface is arranged a transparent optical filter having an upper surface and a lower surface. The upper surface is adapted for the passage of a minor portion of light from the cavity of the housing to the light-emitting surface and, at the same time, the upper surface is adapted to reflect most of the light from the cavity of the housing back to the lower surface. On the lower surface of the transparent optical filter facing the LED is arranged a spatial optical structure adapted to scatter light from the cavity of the housing onto the upper surface and at the same time is adapted to scatter light reflected from the upper surface back to the spatial optical structure opposite the bottom of the cavity of the housing and possibly also opposite the side surfaces of the cavity of the lighting module.

摘要： The light-guiding optical system comprises at least one light source (2) and a light guide (1) for coupling and guiding light rays (10) emitted by a light source (2). Furthermore, the light guide (1) may comprise a decoupling surface (4) on its rear side (13) and an output surface (3) for the exit of light rays (10) decoupled by the decoupling surface (4) on an opposite front side (14). The decoupling surface (4) comprises: (i) first decoupling elements (5) configured to decouple light rays (10) falling onto the first decoupling elements (5) out of the light guide (1) approximately in a pre-determined first output direction (p) to fulfill a first light function, and (ii) a second decoupling element (6) configured to uncouple light rays (10) falling onto the second decoupling elements (6) out of the light guide (1) approximately in a pre-determined second output direction (d), which is deflected from the first output direction (p), to fulfill the second light function.

摘要： The lighting unit (3) comprises a light guide (15) to lead light rays (10) from at least one light source (11) wherein the light guide (15) comprises the front surface (17) and the opposite rear surface (18). The front surface (17) comprises exit areas (30) for the exit of light rays (10) from the light guide (15), and intermediate areas (19) positioned between the exit areas (30) and configured for total reflection of light rays (10) passing along the light guide (15). The lighting unit (3) further comprising a light assembly (23) situated against the front surface (17) of the light guide (15) and comprising optical elements (26) containing a bearing area (14) with which the optical elements (26) are connected to the opposite exit areas (30) directly or indirectly in such a way that transitional layers (24) are situated between the exit areas (30) and bearing areas (14). The optical elements (26) are configured to bind light rays (10) falling onto the exit areas (30) and to emit them from the exit surface (29) of the optical elements (26) averted from the light guide (15), in a predetermined direction or directions.

摘要： The adjustment system comprises at least one pair of adjustment apparatuses. For each optical assembly, one adjustment apparatus is adapted to turn the optical assembly around the turning axis (α; β) independently of the other optical assembly. The adjustment system further comprises an additional adjustment apparatus connected to a first adjustment apparatus and adapted to transfer its movement to the movement of this adjustment apparatus; and a connecting member connected to the additional adjustment apparatus and to a second adjustment apparatus at the same time, and adapted to transfer the movement of the additional adjustment apparatus to the movement of the second adjustment apparatus (. If the additional adjustment apparatus is connected to the first adjustment apparatus and the connecting member is connected between the additional adjustment apparatus and the second adjustment apparatus, turning movement of one optical assembly will automatically induce a turning movement of the other optical assembly.

摘要： A composite lens arrangement for use with a light emitting source directed along an optical axis includes a collimator lens, a beam former lens, a first optical structure, and a member. The collimator lens includes a light collection surface axially opposed to the light emitting source, and an opposite facing light emitting surface. The beam former lens is spaced axially from the light emitting surface, and includes a light collection face axially opposed to the light emitting surface and an opposite light emitting face. The first optical structure is integral to one of the light emitting surface and the light collection face. The member is radially spaced from the optical axis, and extends between, and is attached to, the light emitting surface and the light collection face.
