in practical application, the control logic is that the AC end is powered on, the circuit A works to provide corresponding voltage for the circuits B and E, the circuit B works to supply power for the circuits C and D, the circuit D receives a detection feedback signal of the circuit C after working and can provide a control signal for the circuit E, and the circuit E performs an action of controlling the LED under the power supply provided by the circuit B and the control signal of the circuit D to realize a preset effect.

As shown in fig. 2, in the circuit of the main power supply circuit module, a front stage fuse adds CLC filtering, and the fuse mainly plays a role of overload protection; when the fuse is correctly arranged in the circuit, the fuse can be fused to cut off the current when the current is abnormally increased to a certain height and heat, so that the safe operation of the circuit is protected; the output of the switching power supply contains abundant ripples, which bring adverse effect to a power supply system, and the CLC filter circuit has a certain inhibition effect on the ripples.

The rear-stage BUCK constant-voltage circuit stabilizes the output at DC 12V, and the rear-stage BUCK constant-voltage circuit needs a stable direct-current voltage-stabilizing source and can stably and continuously provide output for a rear-stage circuit; because the load voltage is about 12V, the voltage is stabilized at 12V, the whole system can achieve higher working efficiency, the heat loss is reduced, and the system reliability is improved.

As shown in fig. 3, a diode D2 is used to separate the circuit in the MCU power supply circuit module from the previous circuit V +, and E1E 2 is used to electrolyze and maintain stored energy, so as to ensure the continuous power supply capability of the IC 3;

As shown in fig. 6, a linear switching circuit composed of MOS controls the output of multiple LEDs, thereby making application methods diverse; the control output may also be implemented with a switching circuit.

The MCU outputs high and low levels to U2.18U 2.17U 2.16 to respectively control the on and off of Q1Q 2Q 3, so that the change of output current, namely the on and off of Q1Q 2Q 3 and the change of duty ratio are realized, the change of lamp current average value is realized, the change of lamp brightness is caused, the proportion and brightness of lamps with various colors are changed, and the dimming and color changing effects can be realized.

As shown in fig. 7, the upper cover 1 and the lower cover 2 are detachably connected, thereby facilitating the disassembly and assembly of the housing; the heat dissipation grooves 101 are uniformly distributed and arranged on two sides of the shell, so that good heat dissipation of components in the accommodating space 102 is realized; the heat dissipation groove 101 extends from the top plate 11 to the side plate 12, so that heat dissipation can be realized on the top and the side in the accommodating space 102, and the service life of components is greatly ensured; the inserting groove 103 formed by the vertical plate 21 and the baffle 13 realizes the inserting connection of the vertical plate 21 and the upper cover 1, the width of the vertical plate 21 from top to bottom is gradually increased, the width of the top end of the vertical plate 21 is smaller than the length of the top plate 11, so that after the top plate 11 is inserted into the inserting groove 103, the inserting groove 103 is communicated with the accommodating space 102, and the inserting groove 103 also has a heat dissipation effect, thereby further enhancing the heat dissipation effect of the shell.
