You will want a certain light area distribution, and would use lenses to get this.
Nothing of this kind. Similar effects are observed with coherent light sources, e.g. lasers. LED light power simply adds up.or do the ten LEDs mean interference patterns are produced, and even light cancellation?
Yea, exactly: maybe.So then maybe just one lens type will do?
Asking for the "best" without defining it is useless.so we are saying that B is best?
best light distribution / equal brightness
* smallest spot point
* sharp edges in brightness
Their heatsink will need to be the size of a bus, or need a leaf blower cooling them.
What does specific mean? Specific in which manner?I need a specific light area distribution…
To have ten different lenses will be more expensive, so can we say that it is pointless because there are no optical advantages of having ten different lenses?
i require them to light a wide area.
So for example, say I was doing a 300W LED lamp, and I need a specific light area distribution…
A)….I can do it with one large 300W COB LED with one lens.
Or
B)… I can do it with ten 30W COB LEDs and ten different lenses…each lens shining light in a slightly different direction than all the others, in order to create the total light distribution.
Or
C)....I can do it with ten 30W COB LEDs and ten identical lenses
….so we are saying that B is best?
Thanks, the led light is divergent but gets less in strength as you get more angled from the zenith.......so we need lenses to put out decent light strength to the peripheral areas.
