An illumination device for a photographic enlarger unit consisting of a large number of lights which can be selectively turned on or off has the lights (16) arranged in one or more planes roughly parallel to the negative plane to produce an uneven level of illumination across the negative (27...
There are 2 ways to set up lights in a circuit: in series or in parallel. A series circuit has bulbs set up one after another on a wire. A parallel circuit looks like a ladder with the bulbs in the middle of each rung. In series, the current has to account for every bulb on the...
In other areas, the traffic parallel to the railroad track will have a green light for the duration of the train while the other directions face a red light for the duration of the train. The Chicago Drive/Ivanrest Avenue intersection in Grandville, Michigan, gives Chicago Drive traffic (...
Connecting multiple LEDs in parallel can increase the brightness of the light. You can try connecting multiple LEDs in parallel to improve the lighting effect. Series and parallel connections. Series connections have the advantage of distributing voltage among the individual LEDs, but if any one of ...
Understanding Lights Wired in Series: Explaining Basic Electricity I need some help with a formula, I am constructing some aids for a class room demonstration on basic electricity. I am using lights to demonstrate series and parallel cicuits, also trying to explain some of the basic laws. My ...
Figure2compares our data from the two viewing conditions. The abscissa shows, for Maxwellian-view, the wavelengths that elicited a series of hue sensations, ranging from 100%B to 20%Y & 80%R, in 5% hue steps. (The range of hue ratios is restricted to those that were seen by all part...

All the LEDs are run in series, not parallel, except for the really low voltage strings that run off a small solar panel. The nature of the LED semiconductor itself is such that they share the total voltage (170 volts peak for a 120VAC line) as long as the reverse voltage rating of...
This approach yields a β coefficient for each predictor at each time point across the trial, such that plotting the βs for a given predictor gives a time series showing when, in which direction, and how strongly that predictor explains variance in the signal. A second approach is to model...
The newer ML series are over 600 lumens. I use several of the Maglite 160 lumen lights on a 400 acre farm and can certainly verify the focused distance drop-off claims. Even at 250 yards, you absolutely will not look directly into this beam. This is not a Maglite commercial; I just ...
