The light device comprises a housing (1) covered with a transparent or semi-transparent cover (2) that delimit an inner chamber (3) inside the housing (1), a light unit (5) situated in the chamber (3) and equipped with at least one light source, a cooler (4) associated with the light unit (5), and a tubular cooling conduit (7) that passes through an opening (10) in the housing (1) into the chamber (3) to supply cooling medium (8) from the cooling medium (8) source installed outside the housing (1) to the cooler (4) and comprises a drive means (74) for forced flow of the cooling medium (8) in the tubular cooling conduit (7). The tubular cooling conduit (7) is connected to the cooler (4) in such a way that the cooling medium (8) does not escape from the tubular cooling conduit (7) and cooler (4) to the surrounding space in the chamber (3). Inside the tubular cooling conduit (7), one or more adjacent supply channels (72) are provided to supply the cooling medium (8) to the cooler (4) in one direction, and next to the supply channel (72) or channels (72), one or more exhaust channels (73) are provided to simultaneously discharge the cooling medium from the cooler (4) in the opposite direction out of the housing (1).

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.
