The power is turned on, and at the same time, the voltage necessary for the circuit is formed by the charging current of the capacitor C2 through the resistor R1, and smoothed by the electrolytic capacitor C3 through the diode D4 and the resistor R5, and the voltage for driving the relay RL1 by the constant voltage diode ZD1. do. The charging current of the capacitor C2 is smoothed by the diode D4 to supply a constant voltage to the leakage current detector, the high voltage detector, the short circuit detector, the normal detector and the microcomputer.

Next, the leakage current detecting unit 320 according to the present invention will be described.

The leakage current detection unit 320 is connected to one side of the power supply unit 310 and serves to detect a leakage current generated in the image current transformer.

It receives the leakage current generated in the current transformer (ZCT) as a resistor R34 and puts the charging current of the capacitor C7 to the (+) side of the amplifier U102A, and the resistors R35 and R37 are connected to the (-) side of the amplifier U102A. Amplify at proper magnification.

In the normal state of the two wires passing through the current transformer, the magnetic flux is reversed, so it does not cancel the electromotive force.However, if the equilibrium is broken due to an increase in one of the two wires due to lamp failure, instantaneous blackout, or overcurrent, the amount of electromotive force is increased. The voltage generated by being induced in the coil of the amplifier is amplified by the amplifier U102A of the leakage current sensing unit, and the amplified signal is input through the input port RA0 of the microcomputer unit. At this time, when the microcomputer detects the amplified signal, the gate of the transistor Q5 is triggered from the output port RA1 through the resistor R29 to drop the driving contact of the relay RL1 to cut off the output. At this time, the leakage cutoff display lamp LED 8 of the display lamp driver is turned on through the resistor R39.

Next, the rectifier circuit 330 according to the present invention will be described.

The rectifier circuit 330 serves to rectify the AC input power passing through the leakage current detector by a diode.

This smoothes the charging current of the capacitor C2 with the diode D4, and supplies a constant voltage to the leakage current detector, the high voltage detector, the short circuit detector, the normal detector, and the microcomputer.

Next, the backup power supply unit 340 according to the present invention will be described.

When the AC power is applied, the backup power unit 340 charges the backup power with the power of the rectifier circuit unit. When the AC power is off, the backup power unit 340 operates the real time clock unit configured at one side of the microcomputer unit with the charged backup power to count the self time. It provides a backup power supply.

It consists of LM7805, capacitor C4, resistor R6, LED 1, diode Schottky D15 and supercapacitor EC7.

That is, when AC power is applied, the backup power is charged to the supercapacitor EC7 using the power of the rectifying circuit unit. When AC power is off, the real time clock unit configured on one side of the microcomputer unit is operated as the backup power of the charged supercapacitor EC7.

Next, the power cutoff circuit unit 350 according to the present invention will be described.

The power cut-off circuit unit 350 is connected to the leakage current detecting unit, and serves to cut off the power when the leakage current is detected.

It is connected to one side of the power supply and cuts off the power through the relay RL1.

That is, when the microcomputer unit sends a "H" signal to the transistor Q5 through R29, the transistor Q5 is turned on to flow the current through the coil of the relay RL1 to change the contact to cut off the AC output power.

Next, the dimming control circuit unit 360 according to the present invention will be described.

The dimming control circuit unit 360 operates according to a control signal of the microcomputer unit, and serves to dimm the ceramic metal halide lamp 2 according to a set time period.

It is composed of a dimming controller 361 and a dimming switch 362.

When the control signal is input from the microcomputer, the dimming controller 361 switches the ceramic metal halide lamp L to the power saving in the dimming setting time period stored in the real time clock, and the dimming switch 42 randomly turns on. Dimming can be controlled by the time of.

When the output terminal RB5 of the microcomputer unit is connected and the dimming control signal is input, the transistor Q3 is turned on through the resistor R11, and the ceramic metal halide lamp (L) is saved through the relay RL2 according to the dimming setting time period stored in the real time clock.

Switch the tap terminal of the winding type transformer to adjust the ballast output current impedance so that the ceramic metal halide lamp L has the maximum power (middle tap connection of the winding type transformer) and the saving power [dimming section; First tap connection of wound transformer)] and maximum power.

Next, the power factor correction circuit 370 according to the present invention will be described.

The power factor correction circuit 370 operates according to the control signal of the microcomputer unit, and serves to compensate for the power factor.

It is connected to one side of the power supply and when the saving power is supplied to the lamp according to the control signal of the microcomputer, when the current phase decreases little by little, the power factor decreases.When the transistor Q4 is turned on through the resistor R12 and relayed to the relay RL4, It is configured to match the phase.

Next, the high voltage generating circuit unit 380 according to the present invention will be described.

The high voltage generating circuit unit 380 serves to block the high pressure by inducing high pressure to the secondary of the ballast according to the phase of the AC wave through the control of the microcomputer unit.

The high voltage generating circuit unit 380 cuts the high pressure by inducing high pressure to the secondary of the ballast according to the phase of the AC wave through the control of the microcomputer unit, which is the capacitor C1 and the thyristor through the center tap of the winding of the winding transformer. It is connected to the anode of Q1, and the gate of diester Q1 is voltage-divided by resistor R2 (220K 1 / 2W) and resistor R9 (470Ω), so it turns on when the gate voltage of diester Q1 rises to the sufficient sine wave input. At the same time, the charging current of the capacitor C1 flows, and a high pressure equal to the number of turns is formed at the output terminal of the winding transformer. On the contrary, when the sine wave reaches zero cross and is incident in the reverse phase, the operation of the thyristors Q1 is stopped through the diode D6, and the charge of the charged capacitor C1 is discharged to wait for the next sine wave incident.

On the other hand, when the lamp is normally turned on and the voltage at both ends drops to 100V ~ 150V, the voltage division voltage of 220K 1 / 2W and 470Ω will not trigger Q1.

The transistor Q6 is connected to the anode terminal of the thyristor Q1, and is connected to the output terminal RA2 of the microcomputer unit through a resistor R43.

Next, the ballast 390 according to the present invention will be described.

The ballast 390 is composed of a winding transformer connected in series between the AC power output and the lamp.

The winding transformer is composed of a transformer connected in series between the AC power output and the lamp, which is connected to the high voltage detecting unit through three terminals of the dimming transformer connected to the primary of the winding transformer T1, and the high voltage generating circuit unit through the dimming transformer tab terminal. And the relay RL1 of the power supply unit is connected to the dimming transformer H terminal, or the relay RL3 of the dimming control unit is connected, and the output of the power cut-off circuit unit is connected to the dimming transformer L terminal.

Next, the lamp lighting state detection unit 390a according to the present invention will be described.

The lamp lighting state detection unit 390a is connected to one side of the ballast and checks the voltage state of the lamp while detecting a high voltage detection, a secondary short circuit (short circuit) of the ballast, and a normal lighting state of the lamp.

It consists of a high voltage detector 390a-1, a short circuit detector 390a-2, and a normal detector 390a-3, which are composed of a 5V single power op amp for high speed, low distortion, and low noise applications.

That is, in order to detect the state of the lamp side voltage, the resistor R28 is connected to the lamp output stage, and the voltage outputted through the voltage is appropriately distributed in each detection circuit to detect the state of the lamp. When the lamp is turned on, the high voltage of 2.5KV or more is generated by the 22OV input voltage. When the lamp is normally turned on, the voltage is lowered to about 10V at the moment when the high voltage is stopped and then slowly stabilizes, indicating the voltage of about 100V ~ 150V.

And, to set the reference voltage (2.5V) to the comparator of each detector is configured to be set through the resistor R51 (5.1KΩ) and resistor R52 (5.1KΩ) connected in parallel to the power supply terminal (VCC 5V).

The high pressure detector 390a-1 passes only the high voltage pulse through the filter consisting of the capacitor C5 and the resistor R22 through the diode D11 to apply the high voltage signal to the positive terminal of the comparator U101B. do. At this time, the zener diode ZD6 is used to prevent the voltage of more than 5V from entering the comparator U2B. In addition, whenever a voltage higher than the reference voltage (2.5V) of the comparator U101B (-) terminal is applied as (+), a short-circuit square wave is outputted and smoothed to the resistors R27 and C11 through the diode D9 to generate high voltage. Ensure that the "H" voltage is maintained.

When the lamp side is shorted, the short circuit detecting unit 390a-2 maintains the voltage of the lamp side OV, so that the voltage divided between the resistor R23 and the resistor R24 through the resistor R28 is also applied to the negative terminal of the comparator U101C at 0V. Will be. When the reference voltage drops below the positive (2.5V), the output of the comparator U101C remains at " L ". The electrolytic capacitor EC5 prevents the direct inflow of high voltage at the time of lighting and prevents the voltage of 5V or more from being applied to the comparator U101C by using the Zener diode ZD4.

When the normal detection unit 390a-3 stops generating high voltage and starts to light normally, the normal detection unit 390a-3 gradually starts to stabilize from 10V and maintains a voltage of 100V to 150V, thereby maintaining the voltage applied to the resistor R30 of the comparator U101D through the zener diode ZD5. If the voltage of (+) terminal is higher than reference voltage (-), it produces "H" output. When the voltage across the resistor R30 is higher than the zener voltage of the zener diode ZD5, current begins to flow and the voltage is induced in the resistor R32. When the voltage on the lamp side is less than 180V higher than the maximum voltage when the lamp side voltage is normally turned on by the resistance distribution of the resistors R24 and R30, the "L" output comes out, and when the voltage exceeds 180V, the "H" output comes out. Electrolytic capacitor EC6 also plays a role of preventing direct inflow of high pressure generated during lighting.

Next, the microcomputer 390b according to the present invention will be described.

The microcomputer 390b controls the operation of the lamp by cutting off the high pressure after the lamp attempts to turn on for a predetermined time when there is no lamp failure or the lamp through the lamp lighting state detection unit, and itself operates a high efficiency ballast mode and a dimming ballast. Switching control to select one of mode and power factor compensation mode, and transmits data signal about current lighting status of lamp and defect according to external control command signal transmitted through bidirectional control system and interface, and in dimming ballast mode. This function performs automatic dimming at the set time through Real Time Clock.

It consists of the PIC16F1508 one-chip microcomputer.

That is, a signal amplified by the leakage current sensing unit by the voltage division of the resistors R35 and R37 of the leakage current sensing unit is input to the input port RA0, and is connected to the transistor Q5 of the power interrupting circuit unit through the resistor R29 at the output port RA1. Turns on the power-off signal to Q5, is connected to the transistor Q6 for switching the thyristors Q1 through the resistor R43 at the output port RA2, and controls to drive the high-voltage generating circuit portion, and composed of a dimming controller and a dimming switch at the output port RB5 The dimming control circuit unit 360 is connected to control the dimming control of the ceramic metal halide lamp 2 according to the time zone set as the dimming control circuit unit, and a bidirectional control interface and a time correction connector unit are connected to the input port RB7. The external control command signal received from the bidirectional control terminal is input and the display lamp is driven through the resistor R40 at the output port RC0. Is connected to LED10 of the display lamp driver through resistor R42 at output port RC1, and is connected to LED8 of the display lamp driver through resistor R39 at output port RC1, and is displayed via resistor R36 at output port RC3. It is connected to LED7 of driving part, and is connected to LED6 of display lamp driving part through resistor R33 at output port RC4, and the output side of comparator U101B is connected to input port RC5 through diode D9, resistor R27, and capacitor C11 of high voltage detection part. The high voltage detection signal of the detection section is input, the output side of the comparator U101C of the short circuit detection section is connected to the input port RC6, the short circuit detection signal of the short circuit detection section is input, and the output side of the comparator U101D of the normal detection section is connected to the input port RC7. The normal detection signal of the detector is input.

In addition, when the manual return switch SW2 is connected to the output port RC4, and the LED6 of the display lamp driver is not driven, the manual return switch SW2 is switched to the input port to receive the push signal of the manual return switch SW2.

The manual return switch (SW2) maintains an "H" signal at the microcomputer unit when it is not pressed by R38 connected to a 5V power supply, and transmits an "L" signal to the microcomputer unit when the switch is pressed, thereby turning off the power supply. The holding current of transistor Q5 in the circuit portion is turned down to " 0 " to be turned off.

The microcomputer unit according to the present invention includes a real time clock unit 390b-1 on one side.

The real time clock unit 390b-1 is set in accordance with the dimming standard of the ceramic metal halide lamp in the dimming ballast mode, and then performs automatic dimming at a set time period.

This consists of the MCP7940 real-time clock.

The real time clock unit receives power from a backup power supply unit at one side.

When the AC power is applied, the backup power unit 340 charges the backup power with the power of the rectifier circuit unit. When the AC power is off, the backup power unit 340 operates the real time clock unit configured at one side of the microcomputer unit with the charged backup power to count the self time. It provides a backup power supply.

In addition, after the lamp attempts to turn on for a predetermined time through the microcomputer according to the present invention, the high pressure is cut off, and the set time is operated as follows.

That is, if the ceramic metal halide lamp is normally turned on within the set time (for example, 20 minutes), the voltage at the lamp output terminal is lowered and the high voltage generation is stopped. At this time, the output of the high voltage generator is "L", the output of the detection detector is "L", the output of the normal detector is "H" state and the microcomputer unit initializes the count and waits. In this case, all the devices in the circuit operate normally.

However, if it does not turn on normally even after the set time (for example, 20 minutes) has elapsed, the microcomputer will drive the transistor Q5 to cut the output and enter the safe shutoff state. At this time, the short cut-off display lamp LED9 and the lamp failure display lamp LED7 are turned on, and the high-voltage oscillation is stopped.

Here, the operation of recognizing that the microcomputer unit is not normally turned on, and attempting to continue lighting for a predetermined time (eg, 20 minutes) by starting counting is performed in the high voltage generating circuit unit.

That is, when the phase of the AC sine wave reaches the phase angle capable of gate firing of the dielister Q1 by the voltage division of 200K 1 / 2W and 470Ω, the dielister Q1 becomes conductive. While charging, high voltage is induced in the secondary of the winding transformer T1. When the opposite phase is incident on the AC wave, the diode D6 stops the operation of the thyristors Q1 and charges the capacitor C1 in the opposite direction to wait for operation at the next waveform.

On the contrary, when the lamp is normally turned on and the voltage at both ends drops to 100V ~ 150V, the high voltage oscillation is automatically stopped because the voltage division voltage of 200K 1 / 2W and 470Ω does not trigger the thyristor Q1.

Due to this driving process, in the present invention, a time (for example, 20 minutes) set through the microcomputer is set, and by setting such a 20 minute standby time, defects occurring in an extremely short time such as a momentary power failure in the circuit are preset. There is an effect that can be blocked.

The time is set to a programming setting in that the high voltage is cut off after the lamp attempts to turn on for a predetermined time through the microcomputer unit.

Next, the display lamp driver 390c according to the present invention will be described.

The display lamp driving unit 390c is connected to one side of the microcomputer unit to display a power input state, high voltage operation and safety cutoff, short circuit state, lamp failure, and dimming ballast mode.

It is connected to the output port RC0, RC1, RC2, RC3, RC4 of the microcomputer part and is connected to the resistors R40, R42, R39, R36, and R33 through the power status indicator lamp (LED10), short circuit interrupt indicator lamp (LED9), and earth leakage interrupt indicator lamp ( LED8), lamp failure indication lamp (LED7), and dimming ballast mode indication lamp (LED6).

In addition, the ballast case 40 according to the present invention is formed to be connected to the waterproof cover pin on one side of the case surface, input the current time to the time compensation setter 410 on one side, the external control command from the remote two-way control terminal It includes a bidirectional control interface? Time correction connector 400 for receiving a signal and passing it to the microcomputer.

The two-way control interface time correction connector 400 is connected to the communication terminal box 800 and the communication interface device 420 for the bi-directional control terminal formed in a 1: 1 of the light of the security light and the street lamp made of a ceramic metal halide lamp. It receives the external control command signal from the bidirectional control terminal 900 of the remote place through the communication terminal box for bidirectional control and is configured to deliver to the microcomputer unit.

Security lamps and street lamps made of conventional ceramic metal halide lamps are formed with a communication terminal box for bidirectional control forming a bidirectional control terminal and a bidirectional wireless and wired communication network at a remote location, and according to the present invention, a bidirectional control interface and a time compensation connector are provided. The interface 400 may be configured to be compatible to be connected to the interface.

The time correction setting unit 410 sets a dimming time zone or a dimming time zone according to the dimming standard of the ceramic metal halide lamp based on the total lighting time of the day, night, and season.

In addition, the ballast case is formed on one side of the case surface, and comprises a dimming time selection switch 500 for setting the dimming time.

In addition, the ballast case according to the present invention is made of a material having excellent heat dissipation, fire resistance, moisture resistance.

The ballast case is formed by mixing an epoxy resin, carbon fiber, heat dissipating material, and flame retardant to form a ballast case, and then applying a desiccant to the inner surface of the ballast case to increase heat dissipation, fire resistance, and moisture resistance.

Specific Gravity (20 ℃) 1.14, Viscosity (cps at 25 ℃) 700 ~ 1100 Epoxy resin 60 ~ 80wt%;

1 ~ 5wt% of carbon fiber with tensile strength of 40 ~ 205 MPa,

Graphite oxide prepared by mixing 30-50 wt% of a mixed solution composed of 60 to 80 wt% sulfuric acid and 20 to 40 wt% nitric acid, 5 to 10 wt% graphite, and 20 to 60 wt% KClO _{3 as an} oxidizing agent was heat-treated at 1,000 ° C. 5-20 wt% of a heat-dissipating agent formed by mixing the synthesized compound and any one or more dispersants selected from Methyltriethoxysilane, Ethyltriethoxysilane, Dimethyldiethoxysilane, and Phenyltrimethoxysilane in the same weight ratio,

1-10 wt% of flame retardant of magnesium hydroxide and aluminum hydroxide having a particle size of 200 nm to 2 μm,

After injecting a composition composed of a mixture of a curing agent of 0.5 to 3 wt%, which is an imidazole or a tertiary amine (benzyldimethylamine), into a mold, a desiccant is applied to the inner surface of the ballast case manufactured through a curing process of 80 to 120 ° C. Apply to a thickness of 1 ~ 3㎛,

The desiccant was added 20 to 70 wt% of styrene-butadiene latex, 40 to 70 wt% of water, 5 to 10 wt% of oleic acid, and 4 to 20 wt% of paraffin wax, and stirred for 20 to 40 minutes. After that, potassium hydroxide (Potassium hydroxide) is characterized in that the mixed composition of 0.5 ~ 2wt%.

The amount of the epoxy resin and the carbon fiber affects the durability characteristics of the ballast case. When the amount of the epoxy resin and the carbon fiber is less than the above-mentioned range, there is a problem that the durability drops sharply and exceeds the above-mentioned range. In this case, since the moldability may be deteriorated, the amount of the epoxy resin and the carbon fiber is preferably limited within the ranges shown.

The heat dissipating material is for smoothly discharging the heat generated inside the ballast case to the outside, and when the amount is less than 5wt%, it is difficult to expect to improve the heat dissipation functionality, and when the amount exceeds 20wt%, the content of other components is relatively high. Since it may be reduced, moldability, fire resistance, moisture resistance, etc. may fall, it is preferable to use the heat dissipation material within the range of 5 to 20wt%.

The flame retardant material is to protect the ballast case from fire. When the amount of the flame retardant is less than 1wt%, it is difficult to impart flame retardant properties, and when it exceeds 10wt%, the flame retardant material has a problem in durability of the ballast case. It is preferable to use in the range of%.

As such, specific examples of the components constituting the ballast case are 80 wt% epoxy resin, 5 wt% carbon fiber, 10 wt% heat dissipation agent, and 5 wt% flame retardant.

The desiccant is to be cured by applying to the inner surface of the ballast case manufactured using a composition formed by mixing the epoxy resin, carbon fiber, heat dissipating material, flame retardant, wherein the coating thickness gives a moisture-proof property to increase the unit cost It should be 1-3 micrometers in the range which can be prevented.

More specifically, after the spray coating of the desiccant to 3㎛ is made by hot air drying for 5 minutes at a temperature of 70 ℃.

Hereinafter, when there is no secondary short-circuit (short circuit), lamp failure or lamp through the components of the green high-efficiency multifunction magnetic dimming ballast according to the present invention as described above, and the specific operation of the dimming control mode Will be described.

[Earth Leakage Blocking]

First, the operation related to the ground fault interruption will be described.

In normal operation, the organic power caused by the current flowing in the input line passing through the zero current transformer (ZCT) cancels out of phase and becomes 0V. However, if one side collapses due to ground fault, the electromotive force is induced in the ZCT by the difference, and after a proper time delay by C7 through R34, it is amplified by the OP amplifier U102A. The input signal is input through the input port RA0 of the microcomputer unit.

At this time, when the microcomputer detects the amplified signal, the gate of the transistor Q5 is triggered from the output port RA1 to drop the driving contact of the relay RL1 to cut off the output. At this time, the earth leakage blocking display lamp (LED8) of the display lamp driver is turned on.

[Secondary short circuit of ballast (short circuit)]

Next, the operation during the second short circuit (short circuit) of the ballast will be described.

Since the voltage at the lamp side maintains OV, the voltage divided by the resistor R23 and the resistor R24 through the resistor R28 is also 0V, and is applied to the negative terminal of the comparator U101C. When the reference voltage drops below the positive (2.5V), the output of the comparator U101C remains at " L ". At this time, the electrolytic capacitor EC5 prevents the direct input of high voltage at the time of lighting and prevents the voltage of more than 5V to be applied to the comparator U101C by using the Zener diode ZD4. At this time, if the output side of the comparator U101C indicates "L", the microcomputer recognizes this and cuts off the relay RL1 through the output port RA1, and the short-circuit indication lamp LED9 of the display lamp driver is turned on.

[Lamp failure or operation without lamp]

Next, the operation of the lamp failure, or no lamp will be described.

If the lamp does not turn on normally, the terminal voltage on the winding type transformer output side, that is, the voltage at both ends of the ceramic metal halide lamp is the same as the input voltage, so this voltage is divided by the resistors R28 and R30 and then Zener diode ZD5. It is applied to the voltage comparator U101D through. At this time, the applied voltage is set higher than the reference voltage (2.5V) of the negative terminal so that the output becomes "H". The microcomputer unit judges that the lamp is not lit or absent when this signal is "H". If the ceramic metal halide lamp is turned on normally and the voltage of the ballast output side, that is, the tube voltage of the ceramic metal halide lamp, is kept below a certain voltage, the divided voltage by the resistor R28 and the resistor R30 does not exceed the voltage of the zener diode ZD5. -) The output is "L" because it is lower than the reference voltage of the terminal. At this time, the microcomputer unit judges that the ceramic metal halide lamp is normally turned on.

That is, if the ceramic metal halide lamp is normally turned on within the set time (for example, 20 minutes), the voltage at the lamp output terminal is lowered and the high voltage generation is stopped. At this time, the output of the high voltage generator is "L", the output of the detection detector is "L", the output of the normal detector is "H" state and the microcomputer unit initializes the count and waits. In this case, all the devices in the circuit operate normally.

However, if it does not turn on normally even after the set time (for example, 20 minutes) has elapsed, the microcomputer will drive the transistor Q5 to cut the output and enter the safe shutoff state. At this time, the lamp failure indication lamp LED7 is turned on, and the high-pressure oscillation is stopped.

Here, the operation of recognizing that the microcomputer unit is not normally turned on and attempting to continue lighting for about 20 minutes is performed in the high voltage generating circuit unit.

That is, when the phase of the AC sine wave reaches the phase angle capable of gate firing of the dielister Q1 by the voltage division of 200K 1 / 2W and 470Ω, the dielister Q1 becomes conductive. While charging, high voltage is induced in the secondary of the winding transformer T1. When the opposite phase is incident on the AC wave, the diode D6 stops the operation of the thyristors Q1 and charges the capacitor C1 in the opposite direction to wait for operation at the next waveform.

On the contrary, when the lamp is normally turned on and the voltage at both ends drops to 100V ~ 150V, the high voltage oscillation is automatically stopped because the voltage division voltage of 200K 1 / 2W and 470Ω does not trigger the thyristor Q1.

As described above, the high-industrial high-efficiency green power-saving multifunction ballast according to the present invention is configured in the microcomputer so that the standby time is set to about set time (for example, 20 minutes) when there is no lamp failure and no lamp. It is possible to block defects occurring in a short time in advance.

[ Real-time clock  through Of dimming control mode  action]

First, when a control signal is input from the microcomputer in the dimming controller 361, the dimming controller switches the ceramic metal halide lamp L to the power saving in the dimming setting time period stored in the real time clock, and the dimming switch 42 is turned on. Dimming control is performed at an arbitrary time.

Here, the real time clock is set by a separate time correction setting device.

Subsequently, the dimming switch 362 switches the wound transformer so that the ceramic metal halide lamp L 2 is sequentially turned on at maximum power, reduced power (dimming section), and maximum power.

That is, the ceramic metal halide lamp (L) 2 has the maximum power (middle tap connection of the winding transformer) and the saving power [dimming section] by switching the tap terminal of the wound transformer to adjust the ballast output current impedance. First tap connection of wire-wound transformer)] and maximum power.

Therefore, in the present invention, in the dimming ballast mode, the ceramic metal halide dimming lamp can be automatically dimmed 1: 1 at any set time through a real time clock, thereby saving energy compared to the conventional method. You can improve it by 60%.
