Abstract
Abstract A ceiling baggage storage combination with lighting fixtures for an aircraft passenger cabin with two lengthwise aisles, has a central and two side baggage storage compartments. The ceiling is made of individual curved ceiling elements that extend approximately between the upper edges of the baggage storage compartments. The combination has tube-shaped fluorescent lamps arranged in a direction lengthwise to the aircraft on a respective ceiling element. The ceiling element (5, 11) is curved approximately as a parabola, whereby the less strongly curved zone extends toward the fluorescent lamp (6) which is partly covered by a cover, so that primarily indirect light enters into the cabin. A reflector (7) is arranged on the side of the fluorescent lamp (6) that faces away from and approximately parallel to the ceiling element (5, 11). The reflector (7) reflects the light emanating from the fluorescent lamp (6) primarily toward the ceiling element (5).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
147 words
A combination of ceiling luggage compartments and lighting fixtures for a passenger cabin of an aircraft, comprising two rows of luggage compartments spaced from each other by an aisle, ceiling elements (5, 11) bridging said aisle above said rows of luggage compartments, said ceiling elements having an approximately parabolic curvature with a curved focal end near one row of luggage compartments and with an open end opposite said focal end near the other row of luggage compartments, lighting means (6, 6a) positioned at said open end of said ceiling elements for directing light primarily toward said ceiling elements and partly toward said one row of luggage compartments, reflector means (7) positioned for closing said open end and reflecting light from said lighting means toward said ceiling elements, and cover means positioned for intercepting light from said lighting means to prevent direct light from entering into said aisle.
Claim 2
Dependent Claim
147 words
A combination of ceiling luggage compartments and lighting fixtures for a passenger cabin of an aircraft, comprising two rows of luggage compartments spaced from each other by an aisle, ceiling elements (5, 11) bridging said aisle above said rows of luggage compartments, said ceiling elements having an approximately parabolic curvature with a curved focal end near one row of luggage compartments and with an open end opposite said focal end near the other row of luggage compartments, lighting means (6, 6a) positioned at said open end of said ceiling elements for directing light primarily toward said ceiling elements and partly toward said one row of luggage compartments, reflector means (7) positioned for closing said open end and reflecting light from said lighting means toward said ceiling elements, and cover means positioned for intercepting light from said lighting means to prevent direct light from entering into said aisle.
Claim 3
Dependent Claim
46 words
The combination of claim 1, wherein said open end of said parabolic curvature of said ceiling elements is located above said other row of luggage compartments, and wherein a portion (8a) of a luggage compartment in said other row forms said cover means for intercepting light.
Claim 4
Dependent Claim
27 words
The combination of claim 1, wherein said cover means comprise a separate cover element (12) positioned to intercept light that would otherwise enter directly into said aisle.
Claim 5
Dependent Claim
44 words
The combination of claim 1, wherein said luggage compartments comprise lids positioned to approximately face each other across said aisle, said lids sloping downwardly and towards said aisle so that a horizontal spacing between two lids facing each other increases toward said ceiling elements.
Claim 6
Dependent Claim
41 words
The combination of claim 4, further comprising a gap (2b) between a front edge of an upper ceiling wall (2a) and an upper edge of a respective compartment lid for light to directly pass through said gap into said respective compartment.
Claim 7
Dependent Claim
41 words
The combination of claim 4, wherein said lids of at least one of said two rows have a convex aisle facing surface positioned to receive direct light (15) from said lighting means and to reflect indirect light (15a) into said aisle.
Claim 8
Dependent Claim
21 words
The combination of claim 4, wherein said lids assume an open position wherein said lids reflect light toward said ceiling elements.
Claim 9
Dependent Claim
32 words
The combination of claim 4, wherein said lighting means are so positioned relative to said luggage compartments that direct light enters into said luggage compartments at least when said lids are open.
Claim 10
Dependent Claim
21 words
The combination of claim 1, wherein said parabolic curvature of said ceiling elements is experimentally determined for an optimal light reflection.
Claim 11
Dependent Claim
25 words
The combination of claim 1, wherein said lighting means comprise elongated fluorescent bulbs arranged in a column at said open end of said ceiling elements.
