SCOPE This document covers the general recommendations for cabin lighting in order to provide satisfactory illumination for,
6、 but not limited to: a. Boarding and deplaning b. Movement about the cabin c. Reading d. Use of lavatories e. Use of work areas f. Using stowage compartments, coat rooms, and closets g. Using interior stairways and elevators (lifts) SAE INTERNATIONAL AIR512F Page 2 of 11 1.1 Design Goals - Visual Th
7、e designer should strive to provide a comfortable visual environment by proper consideration of: a. Quantity of Light: The amount of illumination required at each area or location to perform the pertinent visual task. b. Quality of Lighting: The brightness distribution, including contrasts in the fi
8、eld of view. This includes the surrounding area, that is, seat backs, carpeting, bulkheads, overhead, etc., as well as brightness of light sources and fixtures. The values will be influenced by the color, texture, and finish of the materials. Visual comfort is very much dependent upon the quality of
9、 the lighting. 1. Brightness distribution is affected by glare (excessive brightness in the field of view), both direct and reflected, the source of which can be the light sources in the cabin, or light sources exterior to the cabin, such as the sun. The reflected glare may come from shiny, specular
10、 surfaces inside the cabin, or airplane parts, such as the wing on the exterior. 2. By choice of colors and brightness, claustrophobic effects may be reduced. 1.2 Design Goals - Electrical and Mechanical The designer should strive to accomplish the above with: a. Adequate hardware design with consid
11、eration given to: 1. Minimal weight 2. Reliability of equipment and lamps 3. Ease of maintenance b. Safety 1. Electrical 2. Thermal 3. Moisture proof, as required 1.2.1 Illumination Design Errors a. Improper quantity of light - too much as well as too little b. Inadequate quality of lighting 1. Impr
12、oper distribution 2. Exposed light sources - direct glare 3. Improper consideration of secondary surfaces that absorb or reflect light - brightness distribution, colors, reflected glare, etc. c. Difficulty of maintaining lighting systems SAE INTERNATIONAL AIR512F Page 3 of 11 1.2.2 Ingredients for G

Induced Signal Susceptibility Category B Radio Frequency Susceptibilty (Radiated or it is the luminous intensity of any surface in a given direction per unit of projected area of the surface as viewed from that direction. LUMINOUS FLUX: Luminous flux is the time rate of flow
21、 of light. LUMINOUS INTENSITY: Luminous intensity of a source of light in a given direction is the luminous flux per unit solid angle in the direction in question. Hence, it is the luminous flux on a small surface normal to that direction divided by the solid angle (in steradian) which the surface s
22、ubtends at the source. SAE INTERNATIONAL AIR512F Page 11 of 11 LUX: Lux is the unit of illumination when the meter is the unit of length. It is equal to 1 lm/m2.NOSING: The leading edge of the tread. TREAD: The horizontal or nearly horizontal surface of a step. RISE: The vertical distance between no
23、sings of adjacent steps or, in the case of the bottom tread, the distance between the bottom nosing and the adjoining landing.RISER: The vertical (or nearly vertical) face of a step connecting adjacent treads.RUN: The dimension of the tread in the direction of travel measured horizontally between ad
24、jacent nosings (i.e., the full horizontal tread dimension less the overlap of a projecting nosing). Also known as the Tread Depth or the Going.FIGURE 1 - NOMENCLATURE AND STEP DIMENSIONS PERCEIVED OBJECT COLOR: The quality of an object or substance with respect to light reflected by the object, usua

SUBJECTIVE BRIGHTNESS: The subjective attribute of any light sensation giving rise to the percept of luminous intensity, including the who
26、le scan of qualities of being bright, light, brilliant, dim, or dark. (The term “brightness” often is used when referring to the measurable “photometric brightness”. While the contrast usually makes it clear as to which measuring is intended, the preferable term for the photometric quantity is “luminance”, thus reserving “brightness” for the subjective sensation.)
