Abstract
An LED drone light of high power and very light weight has an LED circuit board cooled by a foamed metal matrix of copper or aluminum. Preferably bonded to a disc or puck which is thermally bonded to the back of the PCB, the foamed metal matrix can be cooled by a small fan attached to the light's housing.
Claims19
A lightweight LED light device on a drone, comprising:
- a housing secured on the drone,
- a single circuit board within the housing and including one or more LEDs and LED drive and control electronics,
- a focusing optic for each LED,
- a heat sink thermally connected to the circuit board, the heat sink including a lightweight foamed metal matrix thermally bonded to a thermal heat sink base or puck secured to a side of the circuit board opposite the LED and electronics, the foamed metal matrix being exposed to air for LED cooling when the drone is flown, and
- wiring connected to the LEDs and extending through the housing for connection to a power source carried on the drone,
- whereby the foamed metal matrix helps minimize weight of the drone.
