Abstract

The current adjustment apparatus includes a communication interface, a current generating module, and a current adjustment module. The current generating module includes a microprocessor, a memory forstoring a current setting parameter, and a current generating unit; the memory and the current generating unit are electrically connected to the microprocessor. When the current adjustment module isnot physically connected to the current generating module, the microprocessor makes the current generating unit generate a driving current in response to the current setting parameter; when the current adjustment module is physically connected to the current generating module via the communication interface, the microprocessor makes the current generating unit generate the driving current in accordance with a setting signal from the current adjustment module, and the microprocessor further overwrites the current setting parameter in accordance with the setting signal when receives a writing signal.

Description

Technical field [0001] The present invention relates to a driving device, and in particular to a driving current adjustment device of a light emitting diode lamp. Background technique [0002] A light emitting diode (LED for short) is a semiconductor element that converts electrical energy into light energy through a semiconductor compound to achieve the luminous effect. Therefore, it has the advantages of long life, high stability and low power consumption. It has been widely used Used in indoor and outdoor lighting, replacing traditional light sources such as fluorescent lamps, HID lamps and incandescent lamps. [0003] Generally speaking, a lamp using a light emitting diode as a light source (hereinafter referred to as a light emitting diode lamp) can be driven by a driving device; the driving device can convert an input power source (for example, AC power) into power suitable for the LED lamp. However, LED lamps developed by different manufacturers have different power specifi...
