Abstract
A lamp for mounting suspended from a ceiling comprising an integrally formed housing and an elongate light source housed within the integrally formed housing, The integrally formed housing comprising two side walls that are angled with respect to a base and wherein the side walls are configured to transmit no less than 75% of light received from the base. The base comprises a plurality of microstructures on a side facing away from the interior of the housing. The microstructures are configured to reflect a portion of the light received at the interior surface of the base at an angle of more than 45 degrees with the interior surface from the elongated light source, back into the interior of the housing.
Claims16
A luminaire for suspended mounting comprising
- a housing;
- and
- an elongate light source housed within the housing, the housing comprising:
- a first side wall;
- a second side wall;
- and
- a base connected to the first and second side walls, wherein the first side wall and the second side wall extend substantially above the base and, wherein:
- a volume bound by the first side wall, the second side wall and the base defines an interior of the housing;
- light emitted by the elongate light source, is received at an interior surface of the base that faces the interior of the housing;
- and
- an exterior surface of the base, facing away from the interior of the housing, comprises a plurality of microstructures that each extend away from the interior of the housing for redirecting a portion of light received at the interior surface of the base from the elongate light source, back into the interior of the housing, wherein the plurality of microstructures are structures on a small scale that are able to redirect and/or reflect light incident thereon and where a microstructure is smaller than 100 mm;
- the luminaire characterized in that:
- the housing is an integrally formed housing;
- the first side wall and the second side wall are flat and are configured to transmit no less than 75% of light received from the base;
- the portion of light is that portion of light at an angle of incidence of more than 45 degrees with the interior surface of the base;
- the housing further comprising a light source coupling element, extending above the base, the light source coupling element connected to the first side wall and the second side wall, the light source coupling element configure to couple the integrally formed housing to the elongate light source, wherein the light source coupling element comprises a supporting structure having an aperture to receive the elongate light source to thereby allow mechanical coupling of the light source to the integrally formed housing.
