Abstract
An aircraft light unit is disclosed herein. The aircraft light unit includes a housing having a first side and an opposing second side, a light coupled to the first side of the housing, a circuit board assembly coupled to second side of the housing, a thermoelectric cooler coupled to the circuit board assembly and configured to dissipated heat from the circuit board assembly, and a heat sink disposed over the thermoelectric cooler and configured to dissipate heat from the thermoelectric cooler.
Claims8
An aircraft light unit, comprising:
- a housing having a first side and an opposing second side;
- a light directly coupled to the first side of the housing;
- a circuit board assembly having a first side and a second side, the first side of the circuit board assembly directly coupled to second side of the housing;
- a spacer having a first surface and a second surface, the first surface of the spacer coupled to and physically contacting the second side of the circuit board assembly;
- a thermoelectric cooler configured to dissipate heat from the circuit board assembly, wherein the thermoelectric cooler further comprises a cold side and an opposing hot side, the cold side coupled to and physically contacting the second surface of the spacer;
- and
- a heat sink disposed over and physically contacting the hot side of the thermoelectric cooler and configured to dissipate heat from the thermoelectric cooler.
