Is there a projector that uses near infrared light as its light source? Can high-power near-infrared LED light source be used as the light source of projector? Is there such a product on the market?
Projectors are designed to "cast shadows", which are invisible to the human eye in infrared light, so such projectors have no use value.
Of course, special uses require special infrared light bulbs, and you may have to modify them yourself.
In short, it is not because of technology, but because there is no market.
