Problems solved by technology

[0011] figure 1 A first disadvantage of the prior art shown is that some ECGs sense the load voltage on the driver outputs 301, 302, and if the load voltage is too low, the ECG goes into a fault state
The second disadvantage is that the output current across the driver output terminals 301, 302 is determined by the ECG, so the output current may exceed the required tolerance of the light emitting element
A third disadvantage: it is not compatible with AC power sources (i.e., the drive input must be ECG)

Embodiment Construction

[0036] Hereinafter, exemplary embodiments of a driver and a lighting module will be explained in more detail with reference to the accompanying drawings. The same or similar elements or elements having the same effect are denoted by the same reference numerals, and repeated descriptions of these elements may be omitted in order to avoid redundancy. The drawings and the dimensional relationships of the elements shown in the drawings to each other should not be considered to be to scale. Rather, individual elements may be shown with exaggerated dimensions for better illustration and / or better understanding.

[0037] exist figure 2 In , an exemplary embodiment of a driver 100 for a light emitting element is shown. The driver 100 comprises voltage inputs 101, 102 for receiving a supply voltage from a unit 200, which may be an AC power supply or an electronic controller (ECG).

[0038] The driver 100 may be used to drive light emitting elements in the form of LED lighting modul...

Abstract

The invention relates to a driver (100) for a lighting module, a method for controlling such a driver and a lighting module with such a driver (100) and a light emitting element. The driver has an input (101, 102) for receiving a power supply voltage from the input unit (200), and a driver output (301, 302) for supplying power to cause the light emitting element to emit light. In addition, the driver has a power switching transistor (135) for controlling the power supplied to the driver output (301, 302). A controller (130) within the driver controls the power switching transistor (135) such that the input unit (200) coupled to the driver (100) can be an AC power source or an electronic controller (ECG).

Description

technical field [0001] The invention relates to a driver for a lighting module, a method for controlling the driver and a lighting module comprising the driver. Background technique [0002] With the advent of light-emitting diode (LED) lights, lighting fixtures that are more efficient and last longer than incandescent and fluorescent lights are available. Compared to fluorescent lamps, LED lamps are made of safer materials because, for example, mercury is not required. Therefore, there is a need to adapt existing luminaires for fluorescent and incandescent lamps to accommodate LED lamps, preferably without replacing the entire luminaire or luminaire. [0003] Currently available light fixtures may simply include an alternating current (AC) power supply (main) for powering an incandescent lamp housed in the light fixture. Other currently available luminaires may include electronic ballasts (also known as electronic controllers, abbreviated ECG) for powering fluorescent lam...
