What is the difference between Spot and Wash Intelligent lighting?
A spot fixture, such as the VL2 (or StudioSpot), generally includes a gobo wheel and produces a hard edged pool of light -- much like an ellipsoidal. A wash unit, such as a the VL4 (or StudioColor), produces a soft edged pool of light -- much like a PAR lamp or fresnel.
How to draw phasor diagrams?
1) (ex: for 360 degree--->10 cm on the paper). 2) Draw simple sinusoidale wave. 3) This wave has a period of 2*pi in rad or 360 in degree (it's a multiple of 2*pi in fact). 4) The next wave will be 120 degree distant from the first wave. 5) So you move 120 degree (or 10/3 cm) from the first starting point (having amplitude=0) of the first wave. 6) Draw the starting point (having amplitude=0) of the second wave at the distance mentioned in 5). 7) Then starting from the point in 6) draw the second wave similar to the first wave. 8) Same procedure for drawing the third wave (repeate procedure 4 till 7 but switch the first wave with the second and the second with the third). 9) The formulas are: 10) In fact when x=pi/2-----------> VL1=Vp=|Vmax| x=pi/2 +2pi/3--> VL2=Vp=|Vmax|
