Abstract: A lamp for a headlamp is provided. The lamp includes at least two light source groups each including at least one controllable light source. The light sources of one light source group are set up for emitting yellow light. The light sources of another light source group are set up for emitting at least one of white or blue light. At least the light sources of the at least two light source groups are arranged for producing light that is collectively emittable.

Abstract: A lighting apparatus may include a light generating device for generating a primary light beam, a phosphor body that can be irradiated by means of the primary light beam and serves for partly converting primary light of the primary light beam into secondary light, and a spectral filter disposed downstream of the phosphor body. The spectral filter may be more highly transmissive to the secondary light than to the primary light where the spectral filter is arranged along a beam axis of the primary light beam incident on the phosphor body. The lighting apparatus may be used in LARP arrangement for vehicle lighting, general lighting, exterior lighting, stage lighting, effect lighting, etc.

Abstract: An irradiation unit includes a pump radiation source for the emission of pump radiation; and a conversion element for the at least partial conversion of the pump radiation to a conversion radiation. During operation of the irradiation unit, the pump radiation is incident in the form of a beam from the pump radiation source on an incidence surface of the conversion element. A first portion of the pump radiation is incident on the conversion element in a central segment of the beam and a second portion of the pump radiation is incident on the conversion element in an edge segment of the beam surrounding the central segment. The conversion element is provided in such a way that a normalized degree of conversion and/or a normalized degree of scattering is lower for the second portion of the pump radiation than for the first portion of the pump radiation.

Abstract: A headlamp for the conversion of an original headlamp of a vehicle, comprising: an input for each light function provided by the headlamp, wherein the input is configured to connect to a line of the on-board network of a vehicle for the associated light function, an output for connecting to an on-board network of the vehicle, a module for simulating a load current for those light functions that require considerably less power in the headlamp than the corresponding light source in the original headlamp, at least one light source with an associated electronic operating device for each light function of the headlamp, and a controller for controlling-the modules for simulating a load current and for controlling the light sources with the associated electronic operating device. The module for simulating a load current for each light source comprises a series circuit arrangement of a resistor and a switch.

Abstract: A socket for a lamp includes a connection which is prepared for retaining at least one light source, an optical element which is prepared for optical coupling to the light source, and a bearing. The optical element is movably mounted by the bearing for adaptation to a position of a light exit unit of a connectable light source.

Abstract: A circuit assembly for simulating a load current from an on-board network having an input connected to a line of the on-board network of a vehicle for connecting to a load, an output connected to a light source which replaces the load. A series circuit formed by a resistor and a switch, wherein the resistor has a resistance in the same order as that of the load to be simulated, and the series circuit is connected in parallel with the input. A switching controller with the input connected in parallel to the input of the circuit assembly, and draws a current from the line of the on-board network for connecting to a load smaller than the load current of the load to be replaced. The circuit assembly is open the switch and actuate the switching controller and to close the switch and deactivate the switching controller.
