Abstract
Abstract The disclosure is directed to a clean room design which has a uniform vertical laminar air flow pattern and which will provide a Federal Standard No. 209A, Class 100, environment in sterile growing areas, around high-speed parenteral drug-filling apparatus, and in like environments. The disclosure is also directed to modular lighting panel designs for use in such a room. A basic modular panel is made up of a frame supporting a perforated panel on the outlet side and an absolute filter on the inlet side. A transition piece connects the filter to the frame, the perforated panel having a substantially larger area than the filter. The modular lighting panels utilize foraminous lenses so selected and located with relation to each lighting unit as to pass substantially the same volume of air per unit time as other modular panels used in the room.

Claim 3
Dependent Claim
35 words
A plurality of first modular panels having a frame, an absolute filter, a housing connecting said filter to said frame and a foraminous member connected to said frame and being substantially larger than said filter;
Claim 4
Dependent Claim
35 words
A plurality of first modular panels having a frame, an absolute filter, a housing connecting said filter to said frame and a foraminous member connected to said frame and being substantially larger than said filter;
Claim 5
Dependent Claim
148 words
At least one second modular panel having a frame, an absolute filter, a housing connecting said filter to said frame, a foraminous lens connected to said frame opposite said housing, a support member connected to said frame and disposed between said housing and said lens, at least one lighting unit connected to said frame and disposed between said support member and said lens, said lens having an open area substantially equal to the open area of said foraminous member of said first modular panel; B. An air-permeable floor; C. A plurality of walls extending from said floor to said ceiling; D. Means to supply air under pressure above said ceiling; and E. Means to remove air from under said floor, whereby air flows from said ceiling to said floor in a substantially vertical laminar pattern that is substantially the same under both said first and said second panels.
Claim 6
Dependent Claim
148 words
At least one second modular panel having a frame, an absolute filter, a housing connecting said filter to said frame, a foraminous lens connected to said frame opposite said housing, a support member connected to said frame and disposed between said housing and said lens, at least one lighting unit connected to said frame and disposed between said support member and said lens, said lens having an open area substantially equal to the open area of said foraminous member of said first modular panel; B. An air-permeable floor; C. A plurality of walls extending from said floor to said ceiling; D. Means to supply air under pressure above said ceiling; and E. Means to remove air from under said floor, whereby air flows from said ceiling to said floor in a substantially vertical laminar pattern that is substantially the same under both said first and said second panels.
Claim 7
Dependent Claim
148 words
At least one second modular panel having a frame, an absolute filter, a housing connecting said filter to said frame, a foraminous lens connected to said frame opposite said housing, a support member connected to said frame and disposed between said housing and said lens, at least one lighting unit connected to said frame and disposed between said support member and said lens, said lens having an open area substantially equal to the open area of said foraminous member of said first modular panel; B. An air-permeable floor; C. A plurality of walls extending from said floor to said ceiling; D. Means to supply air under pressure above said ceiling; and E. Means to remove air from under said floor, whereby air flows from said ceiling to said floor in a substantially vertical laminar pattern that is substantially the same under both said first and said second panels.
Claim 8
Dependent Claim
148 words
At least one second modular panel having a frame, an absolute filter, a housing connecting said filter to said frame, a foraminous lens connected to said frame opposite said housing, a support member connected to said frame and disposed between said housing and said lens, at least one lighting unit connected to said frame and disposed between said support member and said lens, said lens having an open area substantially equal to the open area of said foraminous member of said first modular panel; B. An air-permeable floor; C. A plurality of walls extending from said floor to said ceiling; D. Means to supply air under pressure above said ceiling; and E. Means to remove air from under said floor, whereby air flows from said ceiling to said floor in a substantially vertical laminar pattern that is substantially the same under both said first and said second panels.
