Abstract
Cooling systems for LED headlight bulbs are disclosed. In some examples, a headlight bulb assembly for a vehicle headlight includes a circuit board and a first light emitting diode (LED) on the first side of the circuit board and a second LED on the second side of the circuit board. The headlight bulb assembly includes a shell at least partially enclosing the circuit board. The shell defines a sealed interior fan housing, an air intake on the first side of the circuit board, and an air exhaust on the second side of the circuit board. A circulator fan in the sealed interior fan housing is configured to draw air into the sealed interior fan housing through the air intake. The circulator fan is configured to expel the air from the sealed interior fan housing through the air exhaust.
