When the dial-up or dial-down toggle switch selects any one of the white light and color light illumination modes, the specific working principle of the circuit is as follows:

1. white light illumination mode

The lithium battery in the desk lamp outputs VM through an SDC6083 chip (U4) for charging protection to supply power to the white light lamp bead. When the single chip microcomputer (U2) detects a corresponding switch signal SW1, the single chip microcomputer outputs a PWM signal to control the Q1 to be switched on and off, and then the white light lamp beads start to emit light when current flows through the white light lamp beads. The single chip microcomputer realizes white light brightness adjustment by adjusting the duty ratio of the PWM signal.

2. A color illumination mode.

Because the maximum voltage of the lithium battery is 4.2V, the VM needs to be changed into 5V through the booster circuit to supply power to the color lamp beads, and the booster circuit is shown in figure 7. When the single chip microcomputer (U2) detects a corresponding switch signal SW1, the single chip microcomputer pulls the EN signal high, and the boosting IC (U1) is started to provide a 5V power supply. The RGB pin of the single chip outputs a PWM control signal to drive the MOSFET module Q2 to work, and the drain of the MOSFET module Q2 outputs a DATA control signal, as shown in fig. 4, which is sent to each color lamp to control the color lamp. Each lamp bead contains R, G, B three LEDs (the brightness is configured by 8bit respectively). The color lamp data is refreshed once every certain time. The whole light belt can show the color changing effect.

In addition, a temperature sensor 5 and a sound sensor 6 are arranged behind the LED lamp panel 1 inside the desk lamp, the temperature sensor is used for detecting the temperature of the LED lamp panel, when the temperature exceeds a set value and a PWM pin or an RGB pin of the single chip processor sends a low-level control signal, and at the moment, the white light LED circuit 11 or the color light LED circuit 12 does not work, so that the temperature protection effect is achieved. The sound sensor can play the effect of supplementary toggle switch, and the toggle switch is unclear when seeing night, can send higher sound, and the sound sensor detects sound signal, just gives a start signal of singlechip, and the singlechip is opened according to above-mentioned method control white light mode and is realized the illumination, and is comparatively convenient.
