Abstract
Example embodiments relate to luminaire heads with improved heatsinks. One embodiment includes an assembly, such as a luminaire head. The assembly includes a housing and an electrical component, such as a light source, arranged in the housing. The housing has a first side and an optional second side opposite the first side. At least the first side is provided with a heatsink portion having an outer surface provided with multiple heatsink elements protruding outwardly out of the outer surface. A heatsink element thereof has a base and a top. The heatsink element gradually widens from the top to the base.
Claims29
An assembly, such as a luminaire head (1000), comprising a housing and an electrical component, such as a light source, arranged in the housing, said housing having a first side and an optional second side opposite the first side,
- wherein at least the first side is provided with a heatsink portion having an outer surface provided with multiple heatsink elements protruding outwardly out of said outer surface, wherein a heatsink element thereof has a base and a top, and wherein the heatsink element gradually widens from the top to the base.

An assembly, such as a luminaire head, comprising a housing and an electrical component, such as a light source, arranged in the housing, said housing having a first side and an optional second side opposite the first side,
- wherein at least the first side is provided with a heatsink portion having an outer surface provided with multiple heatsink elements protruding outwardly out of said outer surface, wherein a heatsink element thereof has a base and a top and wherein the heatsink element gradually widens from the top to the base,
- wherein, at the level of the base, a maximal length is at least 1.5 times the maximal width, and
- wherein at the level of the base, a maximal length is between 5 mm and 60 mm.
An assembly, such as a luminaire head, comprising a housing and an electrical component, such as a light source, arranged in the housing, said housing having a first side and an optional second side opposite the first side,
- wherein at least the first side is provided with a heatsink portion having an outer surface provided with multiple heatsink elements protruding outwardly out of said outer surface, wherein a heatsink element thereof has a base and a top, wherein the heatsink element gradually widens from the top to the base,
- wherein seen in a cross section, a base surface area of the heatsink element at the base is at least 10% larger than a middle surface area of the heatsink element halfway between the top and the base, and
- wherein the peripheral wall of the heatsink element, as seen in a longitudinal section extending in a length direction of the heatsink element and as seen in a transverse section extending in a width direction perpendicular on the length direction, is curved between the base surface area and the middle surface area, and runs gradually inwardly from the base to an edge of the middle surface area.
