The utility model discloses a lamp cup type photoetching light source, which belongs to the field of light-emitting diode (LED) photoetching light sources, comprises a lamp cup, and is characterized in that an LED lamp group is arranged in the lamp cup, a first reflecting mirror is arranged below the lamp cup, the first reflecting mirror is sequentially provided with a lens group, a compound eye group and a second reflecting mirror from left to right, and a parallel large lens is arranged below the second reflecting mirror. A light source emitted by the LED lamp set sequentially passes through the first reflecting mirror, the lens set and the compound eye set to be projected to the second reflecting mirror, and then the second reflecting mirror reflects light to the parallel large lens. The defects that electricity is wasted when the LED lamp set is used, the service life is not long and the lamp set is turned on or turned off slowly are overcome, and light rays emitted by the LED lamp set are converged toget
