Steradian.

Candela (cd), unit of luminous intensity in the International System of Units (SI), defined as the luminous intensity in a given direction of a source that emits monochromatic radiation of frequency 540 × 1012 hertz and has a radiant intensity in that same direction of 1683 watt per steradian (unit.The concept of steradian is defined in analogy to the definition of a radian. A radian is a unit angle corresponding to a length of one radius on the circumference of a circle. A steradian is a unit of solid angle (or spherical angle) corresponding to an area of r 2 (one radius squared) on a sphere. Intensity of a light source.The Steradian Trail is an ode to the unparalleled mathematical prowess of Ramanujan, which keeps on throwing up new revelations even today. At the crux of the story lies an obscure method lost in Ramanujan's notebooks, rediscovered by a few shady individuals, who then carry out a massive siege. An intelligently written thriller and a refreshing ...intensity is expressed in watts per steradian. In general, the cost of an irLED is linked to the radiant flux (power). Note: "Radiant flux" is a power measurement and uses the measurement of watts. To allow us to more easily relate to this concept, we can imagine making a choice between a 100-watt incandescent bulb and a 15-watt incandescent ...

The figures below show three different formats for quantifying radiation patterns. All of these have intensity units divided by a solid angle. Since we are using 100 lumens for the source optical power in this model, these plots are in absolute candelas (lumens/steradian). If radiometric units were used, the units would be watts/steradian.The steradian is a useful term for computing the flux at a distance to normalize the radiant power into a standard lens cone angle regardless of the lens used or not. When no lens is used, ie. a flat emitter, the beam pattern is said to be a Lambertian response of 160 deg which is defined by the -3dB point or half power.In radiometry, radiant intensity is the radiant flux emitted, reflected, transmitted or received, per unit solid angle, and spectral intensity is the radiant intensity per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength. These are directional quantities. The SI unit of radiant intensity is the watt per steradian (W/sr), while ...1 steradian is defined as the solid angle that subtends a circular spherical cap of area = r^2. If we accept that a radian can also represent the linear measure = r, then, 1 rad^2 = 1 r^2 = 1 sr. Likewise, the surface area of a sphere = 4 pi r^2 = 4 pi rad^2 = 4 pi sr.

The watt per steradian (W/sr) is a unit of power density in the International System of Units (SI). It is used to measure the intensity of radiation emitted by a point source in a particular direction. The unit is derived from the watt, the SI unit of power, and the steradian, the SI unit of solid angle. One watt is equal to one joule per second.
