Description of the Invention: [Technical Field] The present invention relates to a control device for an LED, and more particularly to a control of each LED by using a power supply frequency, and arbitrarily switching the light-emitting diode to change a light-emitting state in a plurality of change modes. Control device. [Prior Art] After the manufacturing method of the light-emitting diode (LED) breaks through the original monochromatic light limitation, the light mixing technique is used to make the light color type more rich and varied, and has the advantages of power saving and high brightness, so that the light is emitted. The application of diodes in various fields has been greatly expanded. For example, lamp manufacturers have facilitated the production of a wide variety of lighting or decorative lamps using light-emitting diodes as light source parts. After a plurality of single-type LEDs are assembled, a specific driving circuit can be used as the (5) LED color-changing bulb. The existing #LED color light bulb is made by using most of the *light color 4 LEDs as its light source parts, but now the '.ED color light/package is also facing the same problem that is difficult to synchronize in practical applications. β has an independent oscillation. Because each illuminating diode color change lamp 2' uses the oscillation frequency generated by the oscillator as the time-calculated color-changing bulb, it can perform various colors and operations according to the time reference. Two exchanges 'but the frequency of each oscillator is difficult to be exactly the same, there will still be such a mistake in the beasts... Each oscillator - start working fashion is barely said to be synchronized as 7 卞 疋 疋 疋 疋After a period of time difference accumulation, the color filter bulbs are completely lost in synchronization with each other, so the bulb is removed from this j T p " 'no, a messy change. In addition to this, the LED color mode cannot be switched. C has another shortcoming, that is, a variety of colors such as red, blue, and two color-changing lamps adopt a -second instant variable color mode, for example, from red to green, and some color-changing lamps are gradually Korean: more broken%% " The blush k turns slowly to light red' and then slowly turns grayish green and then turns green from light green. But - the day of playing Dan U and then 'will be fixed in the single _ kind: 疋 种 种 种 种 种 种 种 种 种 种 种 。 。 。 。 。 。 。 。 。 。 But make it bothersome and want to change another color change mode. It is also known that a color change mode is used for a long time. [Explanation] From the above description, it is known that when the existing color is discolored, it is faced with a problem that the right side of the device is several times, and it is difficult to synchronize after a period of time. 'And the color change mode is fixed - the mode can't switch the color change mode when asked == solve the above two problems, that is, provide a _ color changing device that can use the alternating color = rate: synchronous control, let several u" devices light up together In the case of discoloration, even if the synchronization is changed over a long period of time and the power switch can be switched by the borrower to switch its color change mode, it is not necessary to fix only one color change mode device. In addition, the present invention can automatically identify the AC power frequency or (4) the system. For example, in China, the AC power is based on the 5· system. Based on this, the LEDs are developed to change the color of the LED every second. § Once the 6 Hz AC power supply is used in Taiwan, Then the action transition of 5 1353569 will change from the original every second to #〇.83 seconds will change the color once. Therefore, the specification will cause an error in the specification. Therefore, the present invention automatically recognizes that the AC power frequency is 5 GHz or _z _, and automatically corrects (4) the error, so that the LED color changing device of the present invention is applied to the 5 〇h Z or the bribe system. The length of the discoloration time is the same. In order to achieve synchronization with the AC power frequency, the control device of the present invention mainly comprises: at least one AC/DC conversion circuit, which converts an AC power source into a DC power source; and the previous AC power frequency sampling circuit is connected to the AC power source. Take out the _ j〇_ Me jtg .*· , frequency, and rotate a pair of continuous pulse waves that should be working frequency; Second, the control circuit has built-in multiple sets of change modes, the control circuit system Connecting an alternating current power frequency sampling circuit to receive the continuous pulse wave, detecting a working frequency of the alternating current power source based on: a continuous square wave, and generating a control signal according to the change mode and the working frequency; the driving circuit is connected to the alternating current The output of the /DC conversion circuit and the control circuit is driven according to the control signal outputted by the control circuit: the LEDs enable the LEDs to operate synchronously. Another object of the present invention is to provide an interchangeable change mode: the magnetic hopper is allowed to use 纟' to use the power switch ‘self-selection-change=by the (four) LED’ to exhibit an appropriate change according to the mode. Only sigh yin:,, reach. Between the above-mentioned AC/DC converter circuit and the control circuit 6 1353569, there is a power-off detection and detection circuit and the power supply circuit. The instrument uses the power-off detection circuit to immediately and & Measure the power of the power supply, if there is a power failure, and then provide a short-term power supply by the above-mentioned energy storage and Yilei two, 伢•路, when the power is off, let the control circuit supply power for a short time. Wait for the power to be restored. In the short power supply time, if the y ^ is restored, you can switch to the next k color mode. If this is the case, the color change lamp will be reset to the original state when f is in the power supply and the power supply cannot be re-powered. Another object of the present invention is to provide a device for automatically determining the operating frequency of the AC power source, so that the Φ-first-polar body is at any operating frequency, and can still be appropriate. Time interval drive / off. In order to achieve the above object, the control circuit is connected to a timing circuit, and the timing circuit determines the operating frequency of the continuous pulse wave to generate the AC power source. The remaining detailed electrical cells and conditions of the present invention are detailed in the following embodiments in conjunction with the drawings. [Embodiment] First, please refer to the figure, which is a circuit block diagram of the color changing device (1) of the present invention (10), including: a small-AC/DC conversion circuit (10) whose input ends are connected to one AC power, convert the input AC power to DC power; - AC power frequency sampling circuit (2Q), the input end is connected to the AC power supply to take out the frequency of the AC power, and send it at its output 7 Continuous pulse wave; - control circuit (3 〇^ circuit (3 〇) One round of mountain, there are multiple sets of change modes built in, the control circuit (20) to receive the two-segment connection to the aforementioned AC power frequency sampling Frequency synchronization, and according to the change; ^ pulse wave 'and pulse wave to generate a control signal with the AC power -^... mode; wrong with the power supply circuit (stream / DC conversion circuit 〃 3 into the end of the connection ^丄◦) DC power supply, Yu Xue, vs T: A !

'Electrical, and providing the result to the control circuit (5 〇), connecting the output of the aforementioned AC/DC conversion circuit ((1) and the control circuit (30), Receiving the DC power control LE to output an appropriate driving signal to the plurality of LEDs (60) according to the control signal to enable the LED (60) to have a synchronously coordinated operational change. The control circuit (30) The power-off detection circuit (3 5) can be used to know whether there is a power-off state, and then the power storage and power supply circuit (40) obtains a short-time power supply when the power-off circuit is powered off, so that the control circuit (3〇) 1353569 Use this short power-off/re-power change to switch to the other-discoloration mode. As shown in the second figure, the above-mentioned AC power frequency sampling circuit, J2 is composed of a light-coupler (21), which is light-weighted. Η; 邛's light-emitting diode Connected to a rectifying diode (3) in series, the input AC power source is rectified by the rectifying diode (2) and the current limiting resistor (23) to become the rectified power supply driver; and the optical coupling (=;; The round out ^ system is connected between the output resistance (2 4) and the ground, the optocoupler is crying: ϋ: the other end is connected to the DC power supply. When the above driver goes to the light of the * The body is guided by a rectified half-wave chord, which can be recorded as a continuous pulse wave on the output resistor (2 4 ) by alternating the photo-electric crystal. See Figure 3 for the eye. The AC power frequency sampling circuit (the continuous square wave system that is widely distributed is input to the control circuit (30), and the control circuit (30) is in accordance with the continuous square wave, and is 'can be typed. If the AC power supply is 5αιΐζ, % ϋ β / is 20ms, and the manpower w _z ' is the difference between the parent cycle and the right parent flow power supply is 60Hz, then each cycle is about 16 _, after the power is turned on, the control Electricity: read you ^ BJ electric 硌 (3 〇) immediately after detecting the first party / after, start a timing circuit, the next time, the 仏 body (05 1) starts timing, detected / skin Then stop timing.
