Why can't LED lights be viewed directly with optical instruments? Why shouldn't LED lights be used for dimming lighting?
Do you mean the LED light source used in optical instruments?Halogen light bulbs used in general optical instruments, because halogen bulbs have very good color rendering, they can be very good to restore the original color of the object.The LED light source has less color rendering than halogen lamps
You can't see it directly with an optical instrument. I'm not sure. The LED luminous principle decide that it is a need to provide a constant current source to the normal functioning of the material, the current technology can achieve analog dimming effect, the same effect can be achieved with halogen lamp dimming, but only simulation, normal function and life of its function is not very good
Light waves are not the same, not close to natural colors
