I'm trying to design a short light pole with a height of 1 ft
(0.3m) to light up an area of 9
[length of 10ft (3m) and width of 10ft (3m)] using an ARRAY of
LEDs. However, I have an issue where I don't know how to calculate
the light intensity of a single LED at each angle when it hit the
surface (assuming no bump or anything, just flat). By that I mean
when the LED hit the surface straight down, I will get the most
intensity. As it spreads further and further away, it will get
dimmer and dimmer and at one point, I will not receive a light at
all. The LED can only spread in ONE DIRECTION (not ALL DIRECTION.
This means the light will NOT spread 360 degree. This is what gave
me the most trouble). Please help!
Homework Answers
lux is taken as 10 because that's equivalent to brightness of street light. That's minimum required for safety.
