تعريف footcandle في الإنجليزية الإنجليزية القاموس.
- The unit of illumination when the foot is taken as the unit of length It is the illumination on the surface of one square foot of area on which there is a uniformly distributed flux of one lumen, or the illumination produced on a surface all points of which are at a distance of one foot from a directionally uniform point source of one candela
- The unit of illumination: one footcandle is onelumin per square foot
- The units of illuminance equal to 1 lumen uniformly incident upon an area of 1 square foot; also, equal to the illuminance at a point 1 foot distant from a 1 candela source
- (fc) the unit of illuminance when the foot is taken as the unit of length It is the illuminance on a surface one square foot in area on which there is a uniformly distributed flux of one lumen, or the illuminance produced on a surface all points of which are at a distance of one foot from a directionally uniform point source of one candela
- a unit of illuminance on a surface that is everywhere 1 foot from a point source of 1 candle
- The unit of illumination when the foot is taken as the unit of length It is the illumination on a surface one square foot in area on which there is a uniformly distributed flux of one lumen
- A term used to describe illumination that is measured in "lumens per square foot " Interchangeable with "lux," which is the metric designation
- A unit of illuminance equal to 1 lumen per square foot
- The average illumination resulting when one lumen of light falls on one square foot of surface Total lumens on surface divided by area of surface equals footcandles
- A unit of illumination equal to 1 lumen ft-2 Full sunlight with zenith sun produces an illuminance of the order of 10,000 fc on a horizontal surface Full moonlight provides an illuminance of about 0 02 fc Adequate illumination for steady reading is about 10 fc Close machine work is required about 30 to 40 fc
- The unit of measure for the density of light as it reaches a surface One footcandle is equal to one lumen per square foot Measured footcandles are sensitive to the distance from the source to the surface of measure (inverse square law) and the angle at which the light reaches the surface (cosine law)
- -Standard unit of measure for illumination on a surface The Average footcandle level on a square surface is equal to the lumens striking the surface, divided by the area of the surface
- The illuminance on a surface 1 ft2 in area on which there is a uniformly distributed flux of 1 lm, or the illuminance produced on a surface all points of which are at a distance of 1 ft from a directionally uniform point source of 1 cd (For SI users, one footcandle equals 10 76 lux )
- A standard measurement of illuminance, representing the amount of illuminance on a surface one foot square on which there is a uniformly distributed flux of one lumen
- A measurement of light level It is equivalent to the light intensity made by one candle at a distance of one foot
