Abstract
Abstract A tier light comprising a lamp, a substantially clear lamp housing having an upper end and a lower end, a plurality of baffles on the housing and spaced apart along the housing to prevent generally horizontal emissions of light through the housing, and a reflector system. The reflector system comprises refracting means on the housing lower end for refracting light passing through the housing generally dominantly.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
102 words
A light comprising a lamp, a substantially clear lamp housing having an upper end and a lower end, said housing including diffusion means for diffusing light passing through said housing, and a reflector system comprising refracting means on said housing lower end for refracting substantially all of the light passing through said housing generally downwardly, and reflecting means on said housing upper end for reflecting the light back into said lamp housing, said reflecting means comprising a reflecting member at the upper end of the housing, and a band mounted on the upper end of the housing and including internal reflective prisms.
Claim 2
Dependent Claim
102 words
A light comprising a lamp, a substantially clear lamp housing having an upper end and a lower end, said housing including diffusion means for diffusing light passing through said housing, and a reflector system comprising refracting means on said housing lower end for refracting substantially all of the light passing through said housing generally downwardly, and reflecting means on said housing upper end for reflecting the light back into said lamp housing, said reflecting means comprising a reflecting member at the upper end of the housing, and a band mounted on the upper end of the housing and including internal reflective prisms.
Claim 3
Dependent Claim
24 words
A light in accordance with claim 1 where said diffusion means comprises diffusion prisms on the interior of the lower end of the housing.
Claim 4
Dependent Claim
24 words
A light in accordance with claim 1, wherein said refracting means comprises refracting prisms on the exterior of the lower end of said housing.
Claim 5
Dependent Claim
97 words
A tier light comprising a lamp, a substantially clear lamp housing having an upper end and a lower end, a plurality of baffles on said housing and spaced apart along said housing to prevent generally horizontal emissions of light through said housing, reflecting means comprising a semi-spherical reflecting member at the upper end of the housing, and a band mounted on the upper end of the housing and including internal reflective prisms, and a reflector system comprising refracting means on said housing lower end for refracting substantially all of the light passing through said housing generally downwardly.
Claim 6
Dependent Claim
97 words
A tier light comprising a lamp, a substantially clear lamp housing having an upper end and a lower end, a plurality of baffles on said housing and spaced apart along said housing to prevent generally horizontal emissions of light through said housing, reflecting means comprising a semi-spherical reflecting member at the upper end of the housing, and a band mounted on the upper end of the housing and including internal reflective prisms, and a reflector system comprising refracting means on said housing lower end for refracting substantially all of the light passing through said housing generally downwardly.
