Like the ink-jet printer nonsense. Loads of nominally working video
projectors around where the lamp has worn out after its 1000 to 2000 hours
and a complete new projector is a little more than the cost of a replacement
discharge lamp .
Anyone done a conversion to high power LED emitter lamp? tips/pitfalls ?
Obviously a number of opto-coupler functions need fudging as well as
disconnecting the original lamp supply and HV ignitor sub-circuit
lamp supply input side optos , ignitor-on , lamp on, half/full brightness
output side optos , ignitor cct ok, lamp on (drawing correct current)
confirmation
Perhaps should only consider projectors that allow colour temperature
setting within the menu structures
any other considerations?
I just saw reference to this LED lamp cluster , anyone sen the spec of the
beam angle for it
