The goniometer can be paired with either a photometer (goniophotometer), for angular luminous intensity
measurements only, or with a spectroradiometer (goniospectroradiometer) if angular color information is required.
alpha]] are the luminous intensity
of the beams incident at the points 0,A,B, and P such values given by the cross and the longitudinal luminous intensity
Luminaire manufacturing tolerances and measurement uncertainties will limit the expected accuracy of the luminous intensity
data to at best a few percent when applied to production luminaires.
The luminous intensity
of monochromatic radiation in a given direction, [I.
The weight saving is achieved through the use of new high capacity, ultra lightweight Lithium-ion rechargeable cells, which provide peak luminous intensity
of 340 and 360 lux at five metres.
5v Class 1 Insulation PCB assemblies RoHS-compliant LEDs Viewing Angle +/-3o[degrees] Yellow: Dominant Wave Length 587nm Luminous Intensity
In fact, at the nanometric scale, the least variation in temperature, luminous intensity
, or flow of energy could cause a robot to deviate significantly from its route trying to accomplish its precise task.
Red, orange, yellow, and yellow-orange lamps use AlInGaP technology to produce typical luminous intensity
of 700 to 800 mcd.
The device does not require auxiliary drive circuitry, and has a luminous intensity
Illuminance, the amount of light that actually falls on an object, is intimately related to luminous intensity
Differences in luminous intensity
are assumed to affect luminous contrast -- and thus distance perception -- as shown by O'Shea, Blackburn, and Ono (1994).
At night, the entire building lights up like a huge, free-form Japanese paper lantern, glowing with a softly luminous intensity
