optical module

Abstract

The invention relates to a light module for electrical and thermal attachment to an energy infrastructure having at least one power supply, each power supply comprising two electrodes, said light module comprising a light source to emit light, wherein the light source is a heat source when emitting light, two electrical contacts to contact the electrodes of the at least one power supply and thereby establishing the electrical attachment between the light module and the energy infrastructure, a control system arranged between the light source and the electrical contacts to control a power supplied to the light source, wherein the light module comprises a measurement system to measure a thermal resistance of the thermal attachment between the light module and the energy infrastructure when establishing the electrical attachment, and wherein the control system is configured to reduce the power supplied to the light source when the thermal resistance is above a predetermined value to protect the light module from overheating. The invention also relates to a method for protecting a light module from overheating.

Description

technical field [0001] The present invention relates to the field of light modules, and more particularly to light modules for electrical and thermal attachment to energy installations. Background technique [0002] The light module comprises a light source to emit light, and is preferably easily attachable to an energy installation having at least one power source, wherein each power source comprises two electrodes. Energy facilities can take the form of well-known halogen filament systems or 2D electrode configurations. [0003] Preferably, the attachment of the light module to the energy installation is done by hand without using any additional tools, for example by clamping and / or magnetic fit. This allows users without technical knowledge to attach light modules to energy installations. However, it is also possible to use screws or to use bolts. [0004] Light sources are often also heat sources when emitting light, and in order to keep light modules small, it is des...

AI Technical Summary

Problems solved by technology

However, the disadvantage of these solutions is that when overheating is measured, the optical module already has some so-called burn time at elevated temperature, which can still cause damage to the optical module

Another disadvantage would be that the user does not get immediate feedback that there is insufficient thermal contact between the optical module and the energy facility
