Description of principle and effect:
When the lamps with different wavelengths need to be replaced or a standby lamp needs to be used because the current lamp (taking the first lamp 40 as an example) is damaged, the rotary table 30 is driven to rotate on the control board 20 by rotating the adjusting knob 70, so that the second lamp 50 is aligned to the position of the light hole 110; at this time, the second lamp panel 340 and the second conductive sheet 230 are closely electrically connected by the elastic member 60, so that a conductive loop can be established between the positive and negative electrodes.

For example, a pair of lamps in the same straight line are in one wave band, and a pair of lamps in the other straight line are in another wave band, so as to meet the requirements of various applications on site.
