Abstract

The invention discloses a driving device, a driver, and an LED light source with the driver. The driving device (8) comprises a programmable memory unit (9) used for storing data corresponding to a target value of an output current, a programming signal circuit (10) configured to provide an electrical signal for writing data into the programmable memory unit (9), and a controller circuit (11) with a controller (14) connected to the programmable memory unit (9) during working, wherein the controller (14) is configured to read out the data stored in the programmable memory unit (9) and to generate a controller output signal for adjusting the output current of the driver (4) based on the data stored in the programmable memory unit (9).

Description

technical field [0001] The present invention generally relates to drives for driving loads. In particular, the present invention relates to a driving device, a driver and an LED (Light Emitting Diode) light source with a driver. Background technique [0002] Drivers for providing output current to drive a load are known. Furthermore, drivers with an adjustable output current are also known, so that the driver current can be set by means of external elements such as resistors, jumpers or switches. However, such drivers only offer a limited selection of output current values, while drivers with a wider selection of output current settings are rather complex, error-prone, and expensive. Contents of the invention [0003] It is an object of the present application to provide a driver for programming the output current of the driver which is particularly robust and inexpensive. [0004] According to a first aspect, a driver is provided for programming an output current of a ...
