Abstract
Linear lamp energy output is tuned by adjusting the reflectivity of reflectors or shade members used to direct, focus and filter energy output of a linear bulb. Reflectivity is reduced in areas of the reflector contributing to high irradiance levels in a target area allowing, for example, overall equalization of irradiance across the target area. An outer surface of the linear bulb may have a modified diameter, light transmission reducing surface treatment or an added sleeve to linear bulb areas contributing to irradiance levels in specific locations in the target area that are higher than desired. Alternatively and or additionally, a lens or shade member having a graduated convergence, reflectivity and or transmisivity may be used.
Claims30
A linear lamp, comprising:
- a housing,
- the housing supporting
- a linear bulb, and
- a reflector having a first area and a second area;
- the first area having a first reflectivity that is less than a second reflectivity of the second area.
A method for adjusting the radiant output of a linear lamp having a reflector, comprising the steps of:
- lowering the reflectivity of the reflector at an area corresponding to a radiant output that is higher than desired.
A linear lamp, comprising:
- a housing;
- the housing supporting
- a linear bulb having a first end coupled to a first side coupled to a middle
- coupled to a second side coupled to a second end;
- and
- a reflector;
- the linear bulb having reduced output at the middle relative to the first side and the second side.
A linear lamp, comprising:
- a housing,
- the housing supporting
- a linear bulb, and
- a shade member having a first shade area and a second shade area;
- the first shade area having a first shade reflectivity that is less than a second shade reflectivity of the second shade area.
A linear lamp, comprising:
- a housing,
- the housing supporting
- a linear bulb, and
- a lens configured to have a convergence that varies along a longitudinal dimension of the lens.
