Problems solved by technology

[0004] However, current LED lighting systems often have the disadvantage that color or brightness may change due to aging or due to replacement of individual LEDs or LED modules
[0005] In addition, due to the blocking of thermal radiation, the secondary mirror ( ) has an impact on temperature management
Also, due to aging and thermal effects, the phosphor of the LED may change

Embodiment Construction

[0014] figure 1 Shown is prior art. The device has a driver module 1 and an LED module 5 comprising at least one LED, the LED module 5 being driven by the driver module 1 . The LEDs of the LED module 5 can be selectively driven through different driving channels (through the line 4).

[0015] The present invention will be described below in conjunction with the embodiments of the LED driving device. The device has a driver module 1 and an LED module 5 driven by the driver module 1, comprising at least one LED, including a memory for storing information related to the LED module 5, wherein the memory may be included in the driver module 1, Or it can be included in the LED module 5, and the information in the memory can be modified.

[0016] The memory is preferably configured in such a way that it is non-volatile, that is to say it retains the data in the event of a disconnection or loss of the supply voltage. For example, flash memory can be used. The memory may be includ...

Abstract

An apparatus for operating LEDs, having a driver module (1), and an LED module (5), actuated by the driver module (1), having at least one LED, having a memory for storing information about the LED module (5), wherein the memory is contained either in the driver module (1) or in the LED module (5), and the information in the memory can be altered. The information in the memory can be altered on the basis of a calibration measurement.

Description

technical field [0001] The invention relates to an LED driving device according to the preamble of claim 1 , and the invention also relates to an LED driving method according to the preamble of claim 27 . Background technique [0002] Such devices are used in lighting systems for colored or planar lighting of rooms, roads or escape routes. Typically, lighting fixtures are driven by a driver device and activated on demand. For this lighting, organic or inorganic light-emitting diodes (LEDs) can be used as light sources. [0003] For lighting, instead of gas-discharge lamps and incandescent lamps, light-emitting diodes are increasingly used as light sources. The efficiency and the amount of light emitted by a light emitting diode continue to rapidly increase, so that it has been used in various fields of daily lighting. However, LEDs are point sources of light and emit strongly concentrated light. [0004] However, current LED lighting systems often have the disadvantage t...
