Hello guys, I 'm going on my winter vacation and i intend to make a desk lamp to my girlfriend , it's an exercise to improve my skills in electronics and learn more about the incredible lights of our simple world. Then I mounted a circuit in which she will be able to control the intensity of light through PWM , and also have an intensity indicator ( bargraph ) . I came here to ask the gentlemen who certainly have more experience than me in this matter, the idea is to use LEDs to achieve this, but when I go to pick one, I get very confused by the available data, such as the angle of each LED , or those lumens ( mcd ).
- What is the best pick for this job ? I mean CFL or LED ? I thought about LED, because they're small and cheap.
I believe i was not clear in my explanation, but what i am trying to ask or start talking about, is what difficulties lie ahead to me, like... i never tried to make a light source, so i don't know about how large the spot will be by using this or that.. got what i meant ? Like, a 21000mcd seens to be a violent value, but maybe for me that never worked with this. Or the lens job at this project.
That feeling of not being clear enough.
