[0016] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict, and the present application will be further described in detail in combination with the drawings and specific embodiments.
[0017] As shown in the accompanying drawings Figure 1 to the accompanying drawings Figure 3The light source adjusting device and the stage lamp using the same are shown in the figure, which comprises a lamp panel 1, a collimating lens 2, a compound eye lens 3 and a condenser 4. The lamp panel 1 is provided with a plurality of white LED lamp beads and a plurality of other color LED lamp beads. The plurality of white LED lamp beads are combined into a white light emitting area 11, and the plurality of other color LED lamp beads are combined into a color mixed light emitting area 12. The compound eye lens 3 has a light uniform part and a light non-uniform part. The incident light of the white light emitting area 11 passes through the collimating lens 2, the light non-uniform part and the condenser 4 in sequence, or the incident light of the white light emitting area 11 passes through the collimating lens 2 and the condenser 4 in sequence. The incident light of the color mixed light emitting area 12 passes through the collimating lens 2, the light uniform part and the condenser 4 in sequence. The light uniform part of the compound eye lens 3 couples the light of the color mixed light emitting area 12 to make it uniform, and the light of the white light emitting area 11 is not uniform, so as to ensure that the center illumination of the light spot is high and the light spot is uniform.

The compound eye array part 31 is opposite to the color mixed light emitting area 12, so that the incident light of the color mixed light emitting area 12 passes through the compound eye array part 31, and the incident light of the white light emitting area 11 passes through the plane part 32. The compound eye array part 31 of the compound eye lens 3 is mainly for the light of the color mixed light emitting area 12, and the plane part 32 is for the light of the white light emitting area 11. In this way, the uniformity of the mixed light of the color mixed light emitting area 12 can be increased without reducing the center illumination of the white light emitting area 11.
