摘要： A lighting circuit comprises a first light source arrangement and a second light source arrangement, of different types, in series. A driver delivers a controllable current to the light source circuit, with an adjustable DC component and an adjustable modulated component, for example an adjustable duty cycle of a superposed pulse width modulated component. This enables control of the contributions to the overall light output flux from the different types of light source.

摘要： A method for controlling an electrically heatable catalytic converter that is supplied, by a starter generator, with an output power belonging to the starter generator, wherein the output power of the starter generator is increased by a PWM method, wherein the eCAT monitors an on-board electrical system supply voltage that arises on account of the increase in the output power, the eCAT is activated if the on-board electrical system supply voltage exceeds an upper threshold value, and the eCAT is deactivated if the on-board electrical system supply voltage falls below a lower threshold value.

摘要： A light-emitting diode LED driver and a LED driving device including the LED driver are provided. The light-emitting diode LED driver includes a decoding circuit that receives a data signal and decodes the data signal to generate display data used to drive LEDs to emit light and display and a recovered clock signal. Further provided is an encoding circuit that encodes the decoded display data by using the recovered clock signal to generate an encoded data signal, where the data signal is encoded in a first encoding format, and the encoded data signal is encoded in a second encoding format.

摘要： Systems and methods for applying light to an environment are provided. A system may include an elongate first body having a first side wall, a second side wall opposite the first side wall, and a bottom wall. The first body may define a lengthwise channel between the first side wall and the second side wall. The first body may have a first groove disposed along an inner surface of the first side wall, a second groove disposed along an inner surface of the second side wall, and a cover which may be coupled to the first body via the first groove and the second groove. The first body and the cover may collectively enclose at least a portion of the channel. The system may include an LED disposed within the channel.
