LED circuit control structure 223 block diagram shown in Figure 3, LED circuit control structure 223 is composed of a capacitor buck regulator power supply 2231, LED controller 2232 and three primary color LED array 2233 (R, G, B), due to These three parts must be installed in the lamp cap, so the power supply is stepped down by a capacitor. Full-wave rectification and voltage regulator diode control circuit; power output 14V voltage for LED array, output 14.6V for LED controller 2232, LED controller 2232 each output (A, B, C) When it is low level (such as A is low level), the green LED is on. If the three output terminals are low level, white light is emitted (green, red and blue LEDs are all on).

LED controller 2232 is the key to LED color change. It can be used with CD4060 controller. CD4060 is a 14-bit binary counter. It contains two inverters. Two external resistors and one capacitor can be used to form an oscillator. When the clock pulse is input (falling edge), the output outputs a count pulse, which has a reset terminal (Reset) when the reset terminal is high. All outputs are low, as shown in Table 1 below:

Table 1         <TABLE border="1" borderColor="#000000" width="_0001"><TBODY><tr><td> Clock in </td><td> Reset </td><td> Output Status</td ></tr><tr><td> <img wi="66" he="42" file="02_image001.jpg" img-format="jpg"></img></td><td> 0 </td><td> Enter the next stage</td></tr><tr><td> <img wi="54" he="45" file="02_image003.jpg" img-format="jpg "></img></td><td> 0 </td><td> unchanged</td></tr><tr><td> any </td><td> 1 </td> <td> All outputs are low</td></tr></TBODY></TABLE>

The working principle of the LED circuit control structure 223 is as follows:

1. The power supply design part is a capacitor buck circuit composed of a step-down capacitor, full-wave rectification and a voltage regulator diode. It is a typical AC/DC converter circuit. It is driven by a regulated regulator of 14V. The power of the LED array is filtered (about 14.5V) for the CD4060 and the reset voltage (high level). The resistor connected in parallel with the capacitor is disconnected from the power supply, and the charge on the capacitor is discharged through the resistor connected in parallel with it. To prevent charging on the lamp cap, the characteristic of the capacitor buck circuit is that when the voltage of the load is much less than 220V, the current on the load is IL≈69C (C is a step-down capacitor, the unit is uF, and the unit of IL is mA); for example, When C=0.47 u F, the current flowing through the load is about 32.4 mA, and this current is relatively stable, and the space size of this power supply design is small.

2. LED color change control is carried out by the binary register CD4060, the clock pulse signal does not use the general oscillator circuit (the CD4060 has two inverters inside, two external resistors and one capacitor can form the oscillator), and In the output count pulse, select the three ends of Q8, Q9 and Q10 to be connected with the negative pole of the LED. When the count pulse output is low level, the corresponding LED string is lit, and the output timing of Q8, Q9 and Q10 is as shown in Fig. 4. The 50Hz period is 0.02s, the Q8 period is 5.12s, the Q9 period is 10.24s, and the Q10 period is 20.48s.

Q8 is connected to the negative pole of the red LED string, Q9 is connected to the negative pole of the blue LED, and Q10 is connected to the negative pole of the green LED string. When Q8 is high level, Q9, Q10 is low level, blue and green LED strings are bright, and after mixing, cyan light is emitted (because Q9, Q10 are low level, Reset end is low level), after 2.56s After turning into R, G bright, emitting yellow light, in the timing diagram (Figure 4), you can see that Q8, Q9, Q10 output are high when Q8 to the fourth cycle, then the three strings of LEDs are off; Once Q8, Q9, Q10 appear low level, the red, green and blue LEDs are all lit, and the light is white, that is, after the red light appears, when the red light ends, it immediately turns into white light, and the Reset end immediately becomes low level, skipping The off-light condition of 2.56s is a clever design on the circuit.

3. The three primary color LEDs (R, G, B) of the three primary color LED arrays can be formed by connecting four LEDs in series, because the tube voltage drop of the red and green LEDs is different from that of the blue LEDs, and various light emitting two The luminous intensity of the polar body is different, and different current limiting resistors are arranged in the LED series circuit, on the one hand, the current of the LED is forced. In addition, the brightness of the light is matched better. The LED adopts a straw hat type LED with a large viewing angle and high brightness.

5 to 6, with the design of the LED circuit control structure 223 of the present invention, the user can achieve various illumination states of the LED light source 21 by operating various switching modes of the switch button 224, as described below. :

Light conversion mode M1: The switching button 224 is lightly pressed to change the color of the light.

Blinking mode M2: continuously pressing the switching button 224 for a specific short time Ta (for example, more than 1 second) will be converted into a fast blinking mode (high blinking frequency), and then continue to press the specific short time Ta to be converted into a medium speed flashing. Mode (low flashing frequency), then continue to press the specific short time Ta, and change to normal mode (not flashing).

Sleep mode M3: continuously press the switch button 224 for a specific long time Tb (for example, more than 3 seconds) to enter a temporary light-off state (if you want to turn on the light again, just press the toggle button 224 again to restore, and restore The light status is automatically set to the color of the light that will be turned on next time.

The use state of the optical fiber whip device of the present invention is as shown in FIG. 7. By exposing the optical fiber 10 exposed to the casing 30 and forming a scattered natural form, when the high-intensity light-emitting diode is energized, the multi-color light emitted is Will pass from the tight end of the optical fiber to the diffused end of the optical fiber, not only forming an infinite number of bright lines of fiber, but also forming a brighter luminous point 14 on its diffused end face; as the color light changes, and the performer Waving, the fiber optic whip device of this creation will emit a dreamy variegation, and the light-emitting points of the top 11 and/or the folds 13 of each fiber 10 will present various residual images, giving the overall Colorful polymorphism, light and shadowy feeling.

The above is only an example, and is not intended to limit the present invention. The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and thus is generally known in the art.
