The operation of the present invention configured as described above will be described.

First, the present invention supplies the 5V power required for the operation of the remote control dimming controller for fluorescent lamps through the 5V DC power supply unit 10, wherein the 5V DC power supply unit 10 is insulated from the 220V AC power supply so as to dim several fluorescent lamps. The dimming signal of the electronic ballast can be controlled directly.

The present invention allows the user to turn on / off the fluorescent dimming electronic ballast by pressing the remote control or key button or control the fluorescent dimming signal from 0 to 10V to adjust the brightness of the fluorescent lamp, or to sleep-out and wake-up functions. In / Alarm), Step Dimming (4-Scene), Delay Off (Fade-Out + Power Off), Delay Off (Fade-In + Power On).

That is, when the user sends a signal using the remote control or presses a key button to send a signal, the remote control signal receiving unit 20 or the key signal receiving unit 30 receives the signal.

The remote control signal receiver 20 receives the infrared signal from the remote control transmitter, converts the signal into a logic signal, and sends the signal to the microcomputer 40.

In addition, the key signal receiving unit 30 has eight Tact switches for each signal in the remote control dimming controller for fluorescent lamps, so that the user can directly manipulate them by hand.

Therefore, in the microcomputer 40, the first power switch unit 60, the second power switch unit 70, the first voltage control unit 80, and the second voltage control unit 90 by a built-in program according to the input signal. Control independently.

When the PWM duty of the microcomputer 40 is between 0 to 100%, the dimming (+) terminal voltage is controlled between 0 to 10V DC according to the signal to control the brightness of the fluorescent lamp to the brightness desired by the user.

For example, the first voltage controller 80 and the second voltage controller 90 receive the PWM signal from the microcomputer 40 and control the voltage of the dimming (+) terminal to be 0V DC when the PWM duty is 0%. At this time, the brightness of the fluorescent lamp becomes the minimum brightness, while when the PWM duty is 100%, the voltage of the dimming (+) terminal is controlled to be 10V DC. In this case, the brightness of the fluorescent lamp is the maximum brightness.

That is, when the key signal is received and the remote control signal is received, the LED display unit 50 is turned on. When the scene adjustment mode is entered, the LED of the LCD display unit 50 blinks.

If the morning wake-up time by adjusting the remote controller, the first power switch unit 60 and the second power switch unit 70 is turned on at the time reserved by the control of the microcomputer 40 to turn the fluorescent lamp to the minimum brightness. Turn on and slowly fluoresce the fluorescent lamp to the brightness before turning off for 30 minutes, then ring the buzzer for about 3 minutes.

In addition, when the delayed on / off key is pressed through the remote control, the fluorescent lamp is turned on to the minimum brightness and gradually turned to the brightness before turning off for 5 minutes (Fade-In), and when pressed again, it is gradually lowered to the minimum brightness for 5 minutes from the current brightness. Turn off the fluorescent lamp after (Fade-Out).

On the other hand, the (Sn) 1, 2, 3, and 4 keys of the remote control transmitter can store the fluorescent lamps of the circuit 1 and the circuit 2 by adjusting the illuminance appropriate for the user's situation, and press the (Sn) key to adjust the brightness of the adjusted scene.

2 shows a circuit configuration of an embodiment of the present invention, in which the first and second power switch units 60 and 70 turn on / off the phototriacs PC1 and PC2 according to the signal of the microcomputer 40. The phototriac is turned off by turning on / off the powder triac (TA1, 2) when 220V AC is at zero voltage by zero voltage switching (ZVS) function.

Since electronic ballasts for fluorescent lamps are capacitive loads, 220V AC is supplied and inrush currents that are several times the rated current flow when the ballast operates.

This may cause the triac to break beyond the maximum allowable current of the powder triac.

Conventional incandescent light remote control switch does not use a phototriac and directly turns on the triac's gate by using a transistor, so the powder triac has a tendency to be destroyed by an inrush current, and the voltage (A2) and the control power of the powder triac 5VDC) is not insulated, so dimming electronic ballasts for fluorescent lamps cannot be directly controlled.

Since the dimming terminals (dimming (+) and dimming (-)) of the dimming electronic ballast for fluorescent lamps are insulated from the operating power of the dimming ballast, several dimming ballasts can be connected in parallel and collectively controlled.

In order to collectively control several dimming signals in one circuit, the operating power of the remote control dimming controller for fluorescent lamps must be insulated from the 220V AC power supply.

The first voltage controller 80 receives the PWM signal from the microcomputer 40 and becomes 0 V DC by the integrating circuit of the resistor R10 and the capacitor C10 when the PWM duty is 0%. The inverting amplifier IC3A The voltage at the pin Pin1 becomes 5V DC and is supplied to the gate of the FET Q1.

At this time, the FET Q1 is turned on so that the voltage of the dimming (+) terminal becomes 0V DC and the brightness of the dimming electronic ballast for fluorescent lamps is minimized.

In addition, when the PWM voltage of the microcomputer 40 receives the PWM signal from the microcomputer 40, the second voltage controller 90 becomes 0V DC by the integrating circuit of the resistor R19 and the capacitor C12, and the inverting amplifier IC4A. As a result, the voltage of the pin Pin1 becomes 5V DC and is supplied to the gate of the FET Q2.

At this time, the FET Q2 is turned on so that the voltage of the dimming (+) terminal becomes 0V DC and the brightness of the dimming electronic ballast for fluorescent lamps is minimized.

If the PWM duty is increased, the VDC of the capacitors C10 and C12 is increased by the integrating circuit of the resistors R10, R19 and the capacitors C10 and C12, and the inverting amplifier IC3A, ( The voltage at pin 1 is reduced by IC4A to reduce the drain current of FETs Q1 and Q2.

As the drain current of the FETs Q1 and Q2 decreases, the dimming voltage increases and the dimming voltage is divided by the voltage dimming by the resistors R26 and R18, and the buffer IC3B. ), (IC4B) is fed back to the inverting amplifier of IC3A (IC4A).

Therefore, the dimming (+) voltage is controlled to be twice the voltage of the capacitors C10 and C12 and stabilized.

The dimming (+) current increases (the number of dimming electronic ballasts for fluorescent lamps is increased) and the dimming (+) voltage increases, but the inverting amplifiers (IC3A) and (IC4A) are increased through the buffers (IC3B) and (IC4B). As it is fed back, the dimming (+) voltage is controlled to be twice the voltage of the capacitors C10 and C12 and stabilized.

Even if several dimming electronic ballasts for a fluorescent lamp are connected to one circuit, the dimming (+) voltage is controlled according to the PWM duty of the microcomputer, so that the brightness of the fluorescent lamp can be controlled stably.

On the other hand, when the PWM duty reaches 100%, the VDC of the capacitors C10 and C12 becomes 5V DC by the integrating circuits R10 and C10 and R19 and C12, and the inverting amplifiers IC3A and IC4A. As a result, the voltage at the pin 1 becomes 1 V DC or less, and the drain currents of the FETs Q1 and Q2 further decrease.

At this time, the voltages of the FETs Q1 and Q2 gradually increase and are divided by the voltage dimming (+) / 2 by R17 (R26) and R18 (R27) to invert the amplifier IC3A through the buffer IC3B and IC4B ( Since the voltage is fed back to IC4A), the voltage of the dimming terminal becomes stable when it reaches 10V DC.

That is, when the voltage of the dimming terminal becomes 10V DC, the brightness of the dimming electronic ballast for fluorescent lamps is maximized.

The present invention as described in detail above can be used to wake up, bedtime, fluorescent light on / off and dimming up / down, delayed lighting / lighting, new adjustment / selection by remote control, and the weather, bedtime, fluorescent light in the fluorescent remote controller dimmer controller. On / Off and Dimming Up / Down, Delay On / Off, and the current time can be adjusted.

In addition, of the present invention Fluorescent remote control dimming controller can be connected to several dimming electronic ballasts for fluorescent lamps, so it can maintain user-adjusted brightness even if one or two ballasts do not operate.

In addition, the present invention, in the wake-up mode, turn on the fluorescent lights of the circuit 1 and the circuit 2 at the minimum brightness at the scheduled time and gradually brighten the fluorescent lights to the brightness before turning off for 30 minutes to make the environment as if it was a sunrise and then buzzer about 3 It wakes up for a minute, so you can wake up refreshedly.In the sleep mode, when the set time is reached, the fluorescent lamps of Circuit 1 and Circuit 2 are gradually lowered to the minimum brightness for 30 minutes at the current brightness, and then the fluorescent lights are turned off so you can fall asleep comfortably. It has the effect of making it work.

In addition, the present invention turns on the fluorescent lamp to the minimum brightness by pressing the delayed light key and gradually lowers the brightness before turning off for 5 minutes (Fade-In), so that the eye's iris and optic nerve, which are adapted to darkness, are less impacted. Pressing the delayed light off key, on the contrary, gradually lowers the current brightness to the minimum brightness for 5 minutes (Fade-Out) and then turns off the fluorescent lamp so that the lamp does not need to be turned on again even after the lamp is turned off. Some degree of lighting is maintained, so you can see what you need, and you don't have to switch it on again, which saves you power.

In addition, the present invention does not immediately turn off the lamp when the power switch off when used in the home, and after being turned off after maintaining a low light state for a certain period of time to give a time for the human eye to adapt to the dark, less impact on the iris and optic nerve Can give
