Abstract

A cooling system for a modular light emitting diode (LED) lighting fitting includes a heat sink, at least one cooling fan located at an upper portion of the heat sink and inducing heat radiating from the heat sink to an outside to cool the heat sink, at least one thermoelectric element provided at a lower portion of the heat sink and having a heat absorbing part in contact with the LED lighting fitting at a lower portion thereof and a heat radiating part in contact with the heat sink at an upper portion thereof, and at least one temperature sensor mounted at the lower portion of the heat sink. The cooling fan is controllably driven to cool the LED lighting fitting according to whether or not a temperature measured by the temperature sensor reaches a preset temperature.

Description

technical field [0001] The present invention relates to a cooling system for modular light-emitting diode (LED) lighting fittings, which is installed on the upper part of the LED lighting fittings and capable of cooling heat from the LED lighting fittings more efficiently and rapidly. Background technique [0002] The invention of a lighting device called an incandescent lamp is beneficial to mankind because it frees man from darkness and thus enables man to work at night. Therefore, human civilization develops more rapidly. [0003] Since then, human efforts have been made to develop lighting devices that can emit brighter light while consuming less power. As a result, many lighting devices (such as fluorescent lamps, energy-saving lamps, halogen lamps, etc.) have been invented and used in our daily life so far. [0004] With recent advances in light emitting diode (LED) elements that emit light when current flows, interest has been shown in utilizing the characteristics ...
