Description

technical field

[0001] The present invention relates to lighting technology.

[0002] More specifically, the present invention relates to LED lighting devices comprising a heat sink structurally associated with said device. Background technique

[0003] It is well known that a negative characteristic of high-power LED lighting is the high temperature generated by the individual LEDs forming the lighting source, compared to optimal optical and color performance and extremely low power consumption.

[0004] It is also known that in order to avoid overheating and subsequent irreversible damage to the LEDs, it is essential to supplement the above-mentioned luminaires with suitable heat sinks to ensure proper cooling of the components.

[0005] A heat sink adapted to perform the described function, the work of which is based on absorbing the heat generated by the LEDs by conduction and on the basis of further transferring said heat to a plurality of heat sinks of different shape...
