Problems solved by technology

[0004] However, LED lighting systems to date generally have the disadvantage that the apparent color or brightness may change due to aging or through the replacement of individual LEDs or LED modules
Additionally, secondary optics impact thermal management as heat radiation is impeded
In addition, changes in the phosphorescence of LEDs may occur due to aging and thermal effects

Embodiment Construction

[0011] figure 1 An embodiment of the inventive arrangement comprising an LED module 11 and a driver module 10 is shown.

[0012] In the following, the invention is described with the aid of an exemplary embodiment of an operating device 100 for an LED 13 . The device has a driver module 10 and an LED module 11 , which is controlled by the driver module 10 and has at least one LED 13 .

[0013] The driver module 10 has a first terminal 1 via which current can be fed by the driver module 10 to the LED module 11 connected to the first terminal. This current is used to feed the LED 13 . The driver module 10 further includes a second terminal 2 serving as a grounding mechanism (GND).

[0014] The LED module 11 has a first terminal 1 through which a current is fed from the driver module 10 , and also has a second terminal 2 as a grounding mechanism. It is possible to have multiple LEDs 13 on the same LED module 11 . The LED module 11 and the driver module 10 thus have only two ...

Abstract

The invention relates to an operating device for an LED (13), the operating device having a driver module (10) and an LED module (11) with at least one LED (13), the LED module (11) being controlled by the driver module (10 ) control, wherein the driver module (10) has a first terminal (1) designed to feed current to the LED module (11) and a second terminal (2) present as a grounding mechanism (GND), wherein the LED module (11) Current is fed by the driver module (10) via the first terminal (1), and the second terminal (2) is present as grounding mechanism (GND), characterized in that the driver module (10) is temporarily lowered at the first terminal (1) and monitoring the voltage at the first terminal (1), and the driver module is designed to transmit changes in the voltage at the first terminal (1) as information for the LED module (11) to evaluate.

Description

technical field [0001] The invention relates to an LED operating device and an LED operating method. Background technique [0002] Such devices are used in lighting systems to obtain colored or surface lighting of spaces, roads or emergency passages. Usually, the lighting means are now controlled by the operating device and activated as required. For such illumination, organic light emitting diodes or inorganic light emitting diodes (LEDs) are used as light sources. [0003] For lighting, instead of gas-discharge lamps and incandescent lamps, light-emitting diodes are increasingly also used as light sources. The efficacy and light output of light emitting diodes have been enhanced more and more significantly, so they have been used in various applications for general lighting. Light-emitting diodes, on the other hand, are point sources of light and emit intensely focused light. [0004] However, conventional LED lighting systems generally have the disadvantage that the a...
