The light source module 2 further includes a blue LED chip 21 and a white LED chip 22, the blue LED chip 21 is mounted on the top of the housing 3, and the white LED chip 22 is mounted on the outer side of the housing 3. The voltage-stabilizing tube 8 is electrically connected with the light control singlechip 9 through the control panel 4. The light control single chip microcomputer 9 is electrically connected with the blue light circuit driving MOS tube 10 through the control panel 4.

the first innovation point implementation step:

the first step is as follows: firstly, after the LED is electrified, the light control singlechip 9 transmits a control signal to the blue light driving MOS tube 10, and the blue LED is lightened for 3 seconds;

the second step is that: then sending a gradual change signal with the duration of 3 seconds from the brightness of 100 percent to the brightness of 0 percent to the blue light driving MOS tube 10, and gradually changing the brightness of the blue LED from the brightest to the light-off;

the third step: meanwhile, within the 3 seconds, a gradual change signal from 0% brightness to 100% brightness is sent to the white light driving MOS tube 11, so that the white LED gradually changes to the brightest state from the unlighted state, and gradual change switching of blue light and white light within the 3 seconds is realized. After the light-changing switching is finished, the blue light LED is turned off, the white light LED is always kept in the brightest state, and the circuit control flow for gradually changing and switching the light color during the whole starting process is finished.
