Semiconductor light-emitting module and vehicle luminaire
View Patent ↗A semiconductor light-emitting module includes a housing, at least one cooling body accommodated in the housing wherein the cooling body is thermally connected to at least one semiconductor light source, an active cooling device accommodated in the housing, and at least one electronics unit accommodated in the housing, at least for actuating the at least one semiconductor light source, wherein the housing has a leadthrough opening, and the at least one semiconductor light source is arranged in the region of the leadthrough opening.
1. A semiconductor light-emitting module, comprising:
a housing having a front side and a rear side,
at least one cooling body accommodated in the housing wherein the cooling body is thermally connected to a plurality of semiconductor light sources via a substrate or submount common to said semiconductor light sources,
an active cooling device in the form of a fan accommodated in the housing, and
at least one electronics unit accommodated in the housing for actuating the semiconductor light sources and the fan,
wherein the housing has a leadthrough opening provided on the front side, and the electronics unit has a leadthrough which overlaps with the leadthrough on the front side of the housing, and wherein said substrate or submount is arranged in the region of said leadthrough openings so that the semiconductor light sources protrude outside the housing.
2. The semiconductor light-emitting module as claimed in claim 1 , wherein the active cooling device has at least one fan.
3. The semiconductor light-emitting module as claimed in claim 2 , wherein at least one air guide element is accommodated in the housing.
4. The semiconductor light-emitting module as claimed in claim 1 , wherein the housing is a sealed housing.
5. The semiconductor light-emitting module as claimed in claim 1 , wherein the housing has at least one ventilation opening.
6. The semiconductor light-emitting module as claimed in claim 5 , wherein the housing has a plurality of ventilation openings, of which at least some are arranged in the vicinity of the electronics unit.
7. The semiconductor light-emitting module as claimed in claim 1 , wherein at least one further fan is arranged on the electronics unit.
8. The semiconductor light-emitting module as claimed in claim 1 , wherein the electronics unit is integrated in a wall of the housing.
9. The semiconductor light-emitting module as claimed in claim 1 , wherein the leadthrough opening in the housing corresponds to the leadthrough opening in the electronics unit.
10. The semiconductor light-emitting module as claimed in claim 1 , wherein the electronics unit has at least one air passage opening.
11. The semiconductor light-emitting module as claimed in claim 1 , wherein at least one heating source is accommodated in the housing.
12. A vehicle luminaire, having at least one semiconductor light-emitting module comprising:
a housing having a front side and a rear side,
at least one cooling body accommodated in the housing wherein the cooling body is thermally connected to a plurality of semiconductor light sources via a substrate or submount common to said semiconductor light sources, an active cooling device in the form of a fan accommodated in the housing, and
at least one electronics unit accommodated in the housing for actuating the semiconductor light sources and the fan,
wherein the housing has a leadthrough opening provided on the front side, and the electronics unit has a leadthrough which overlaps with the leadthrough on the front side of the housing, and wherein said substrate or submount is arranged in the region of said leadthrough openings so that the semiconductor light sources protrude outside the housing.
