LED projection lamps on the market are all installing a large number of LEDs in the fixtures. In combination with the action of the reflector, the target position is projected and illuminated, but since the light emitted by the LED spotlight is very scattered, no other mechanism is provided to adjust the concentrating effect, which can only be said to be a kind of reflective light, if the projection target has a certain Distance, this type of floodlight is difficult to achieve the required lighting effect.
