A lighting and/or signaling device for a motor vehicle, including an internal chamber housing an optical system and at least one element made of polymer material having a surface directed toward the interior of the chamber, wherein the surface directed toward the interior of the chamber is provided with a sealing layer forming a barrier to the ingress of water molecules to the chamber. The method for manufacturing such a device is also a subject of the invention.

A lamp (100) comprising: a housing (110) having a transparent portion (101); a light source (102) disposed at least partially within the housing (110), wherein the light source (102) is configured to emit light, in use, through the transparent portion (101) of the housing (110); and a heat transfer unit (103) disposed at least partially within the housing (110), the heat transfer unit (103) comprising a heater (105) and a fluid circulator (106), wherein the heat transfer unit (103) is operable in a first mode and a second mode; wherein in the first mode, the heater (105) is turned on, thereby heating a thermal transfer fluid contained within the housing (110), and the fluid circulator (106) is operated to circulate the thermal transfer fluid such that heat is transferred to the transparent portion (101) of the housing (110); and in the second mode, the heater (105) is turned off, and the fluid circulator (106) is operated to circulate the thermal transfer fluid contained within the housing (110) such that heat is transferred away from the light source (102) to the transparent portion (101) of the housing.

There is disclosed a forward cooling headlight comprising a body, a lens coupled to the body and a heatsink coupled to the body. There is also a heatpipe and at least one light. The light is coupled to the heatsink, wherein the heatpipe is coupled to the heatsink at a first end, and to the body at a second end. The heatsink draws heat away from the light, via the heatpipe and towards the body. There can be at least one synthetic jet coupled to the heatpipe to aid in cooling the light. In addition, in at least one embodiment, there can be at least two lights with at least two different drivers with a first driver driving a first light and a second driver driving a second light wherein when each of the lights is lit it is capable of generating a different focal point.

The present invention relates to a cooling system for a lighting module of a vehicle, the system includes at least one heat sink and at least one member for axially circulating a fluid, the heat sink including a first heat-dissipating surface and a second heat-dissipating surface extending in intersecting planes, the heat sink including at least one thermal dissipation member and at least one wall which, together with the axial circulation member and with the first dissipating surface, at least partially delimit a circulation chamber in which the fluid circulates and which opens, via a fluid outlet, onto the thermal dissipation member
