For example, the communication interface unit 160 updates the firmware stored in the memory 120 from the outside using the DMX512 wired interface, and wirelessly receives the control command through the remote device and transmits the control command to the processor 110.

The memory 120 is configured of a nonvolatile memory such as an electrically erasable and programmable read only memory (EEPROM), a flash memory, and the like, and stores firmware used to drive the processor 110.

The signal generator 130 generates and outputs a signal in a form including pulse width modulation (PWM) and SINE, which are used to drive an illumination lamp under the control of the processor 110.

The output signal of the signal generator 130 is input to the lighting lamp driver 170, such as an LED driver IC, a transistor, and adjusts the amount of current applied to the lighting lamp.

For example, the signal generator 130 may adjust the amount of current applied to the lighting lamp by changing the duty ratio at a predetermined frequency when generating a PWM signal, and by changing the frequency at a predetermined amplitude when generating a SINE signal. have.

The sensor unit 250 includes an illuminance sensor 252 and a temperature sensor 251, and detects an ambient illuminance and temperature.

The illuminance sensor 252 detects illuminance so that the main control unit 220 turns on the illumination lamp at night which is less than or equal to the predetermined reference illuminance, and turns off the illumination lamp during the daytime which is greater than the predetermined reference illuminance.

For example, the illuminance sensor 252 compares the detected illuminance with a predetermined criterion and transmits a “high” or “low” signal when the illuminance sensor 252 is less than or equal to the predetermined criterion so that the main controller 220 turns on or illuminates an illumination lamp. Turn off.

The temperature sensor 251 may be a thermistor or the like. The temperature sensor 251 may be installed in proximity to the lighting lamp to detect the radiant temperature of the lighting lamp so that the main controller 220 controls the amount of current of the lighting lamp according to the temperature.

Here, the temperature sensor 251 is preferably installed on the heat sink in order to evenly detect the radiant heat of the light emitting unit 230 composed of a plurality of lighting lamps.

The heat generated from the lighting lamp control system is mainly generated from the power supply unit 240 and the lighting lamp. The power supply unit 240 outputs a fixed voltage, which makes it difficult to control heat generation. However, since the control of the amount of current applied to the lighting lamp is relatively easy, Easy to control

The main controller 220 includes a processor, turns on or off the light emitter 230 at a predetermined reference illuminance, and adjusts the amount of current applied to the light emitter 230 according to the temperature.

The signal generator 130 generates a signal having a frequency, a duty ratio, and a magnitude set by the processor 110 according to the temperature.

In this case, the signal generator 130 outputs a PWM signal having a different duty ratio at a predetermined frequency or a SINE signal having a different frequency at a predetermined size according to the temperature to adjust the amount of current applied to the lighting lamp.

That is, the lighting lamp control system may be automatically turned on or off by dividing the day and the night by the illuminance sensor 252 in a stand-alone manner as described above, and may be manually turned on through the communication interface 160. The ON / OFF signal may be received and turned on and off accordingly.

That is, the lighting lamp control system turns off the system by recognizing the daytime when the ambient illuminance according to the input of the IO block 150 exceeds the standard illuminance, and turns on the system by recognizing it as nighttime when the illumination lamp needs to be turned on below the reference illuminance. To operate.

The DC voltage is used as the driving voltage of each part of the lighting lamp control system including the lighting lamp after the level adjustment.

3A and 3B are waveform diagrams illustrating output signals of the signal generator 130 according to an exemplary embodiment of the present invention.

First, the process of controlling the current amount of the lighting lamp by using the PWM signal and the characteristics of the PWM signal will be described.

The PWM signal is generated by varying the ON / OFF ratio of a predetermined frequency (constant cycle) signal from 0% to 100%. In the present invention, since the PWM signal is controlled by 256 equal parts, the brightness of the illumination lamp is also 256 steps. Controllable by

The PWM signal has the advantage that the on / off period is clear, so it is easy to generate the signal and design the heating part, but the disadvantage is that eyes are easily tired due to flickering (although not directly recognized) due to the on / off. have.

The lighting lamp control system adjusts the amount of current applied to the lighting lamp by generating a PWM signal having a varying duty ratio at a predetermined frequency as follows.

The signal generator 130 generates a first PWM signal applying a predetermined duty ratio t1 / T ₁ to a predetermined frequency f ₁ = 1 / T ₁ and applies the first PWM signal to the illumination lamp driver 170.

Then, the lighting lamp driver 170 adjusts and supplies an amount of current applied from the power supply unit 240 to the lighting lamp so as to correspond to the duty ratio of the first PWM signal.

At this time, when the heat generated by the temperature sensor 251 and / or the amount of current detected by the current detector 180 is greater than or equal to a predetermined reference, the signal generator 130 reduces the duty ratio to less than or equal to the predetermined duty ratio (t2). / T ₁ , t2 <t1) Generate a second PWM signal.

Then, the illumination lamp driver 170 may prevent the system from overheating by reducing the amount of current applied to the illumination lamp by the duty ratio of the second PWM signal.

Next, the process of controlling the current amount of the lighting lamp by using the SINE signal characteristics and the SINE signal with reference to Figure 3b.

Unlike the PWM signal, the SINE signal adjusts the amount of current applied to the lighting lamp by varying the frequency of a predetermined size signal.

When the lighting lamp is turned on using a linear (analog) analog signal, there is an advantage of less eye strain and a smoother color expression than a PWM signal.

The lighting lamp control system controls the amount of current applied to the lighting lamp by generating a SINE signal having a frequency change in a predetermined magnitude as follows.

The signal generator 130 generates a first SINE signal to which a predetermined frequency (1 / T ₂ ) is applied to a predetermined size (Vpp) and applies it to the illumination lamp driver 170.

Then, the lighting lamp driver 170 adjusts and supplies an amount of current applied from the power supply unit 240 to the lighting lamp so as to correspond to the frequency of the first SINE signal.

At this time, when a case in which the heat generated by the temperature sensor 251 or the amount of current detected by the current detection unit 180 respectively exceeds a predetermined reference occurs, the signal generator 130 decreases the frequency below the predetermined frequency (1 / T _3). , T ₂ A second SINE signal to which <T ₃ is applied is generated.

Then, the illumination lamp driver 170 may prevent the system from overheating by reducing the amount of current applied to the illumination lamp so as to correspond to the frequency of the second SINE signal.

4 is a circuit diagram illustrating a lighting lamp control system according to an embodiment of the present invention. Hereinafter, the specification of the main controller 220 implemented in the form of an integrated chip and a configuration example of the peripheral circuit will be described in more detail with reference to FIG. 4.

The power supply circuit corresponds to the power supply unit 240, and receives an AC voltage (eg, AC110 to AC220) within a predetermined range to generate and output a DC voltage having a desired level.

4 illustrates an example in which the power supply circuit generates a 48V DC voltage, in order to drive lighting lamps (eg, LEDs) connected in series by a required number (eg, 12) in consideration of the voltage drop.

Here, the power supply circuit preferably provides at least 80% efficiency with SMPS power supplies from at least 1.0A to 2.0A.

The HR-1000 corresponds to the main controller 220, and is an integrated chip (IC) including an 8-bit processor, an EEPROM, a PWM generator, a SINE waveform generator, an ADC, and an IO block composed of at least 19 function pins.

HR-1000 should be implemented in FPGA during the initial development stage and ASIC in mass production to reduce cost.

HR-1000 may be implemented as a CPLD, but in this case, it is necessary to pay attention to heat generation.

According to the recent chip implementation trend, the HR-1000 uses 3.3V as a driving voltage, and the voltage of 3.3v can be generated by applying a 3.3V output regulator to the power circuit output.

First, the specification of the communication interface 160 (that is, pins 1, 2, and 3) connected to the remote controller 210 among the pins of the HR-1000 to perform wired or wireless communication will be described.

Pin 1 receives the configuration of the internal and external blocks of the HR-1000 received via the RF receiver from the wireless remote device.

In addition, the HR-1000 stores the received signal in the EEPROM and executes it. The next time the system is booted, the HR-1000 operates each unit as set immediately before the system shuts down.

Here, the received signal may be in the form of a packet of 6 bytes including a start byte, a system ID, a command byte, a sub command byte, a dummy byte, and an end byte.

In summary, the RF receiver receives control commands from the remote device, such as the lighting lamp color or duration of operation, and pin 1 interprets the 6-byte packets received via the RF receiver and stores them in the EEPROM.

Pin 2 is a receiver for receiving data using the DMX512 protocol, and pin 3 is a transmitter for transmitting data using the DMX512 protocol.

The wired interface unit 212 converts a received signal from an external device into the DMX512 protocol, and provides pin 2 to the receiver Rx, and pin 3 receives a DMX512 protocol signal from the transmitter Tx. Convert to format and send.

At this time, it is common to apply the RS-482 or RS-422 driver to the wired interface unit 212.

The DMX512 protocol consists of two wires, each of which is responsible for transmitting and receiving, to control a number of connected devices, and is a representative international standard that applies to lighting equipment used with light source-related equipment.

The HR-1000 applies the DMX512 standard to easily obtain the desired data during the development stage, and improves compatibility with many equipments and devices that are commercialized after mass production.

The DMX512 protocol supports 512 control channels per data link, and each channel's data is in 8 bits (0 to 255) units, allowing up to 512 lighting lamps to be controlled in up to 255 steps.

At this time, the HR-1000 may compare the received signal through wired / wireless communication with an ID number (ID, IDentification Number) stored in the EEPROM to determine whether the received signal is for itself.

Pins 4 to 7 are pins for outputting the PWM signal or the SINE signal generated by the signal generator 130.

Pin 4 is connected to the lighting lamp driver 170 which controls a red LED, pin 5 is a green LED, and pin 6 is a blue LED.

The HR-1000 uses an 8-bit processor, which allows 256 levels of color-specific LED brightness control.

That is, since the HR-1000 can control red LEDs in 256 levels, green LEDs in 256 levels, and blue LEDs in 256 levels, the light emitter 230 can express 16777216 (= 256 x 256 x 256) types of colors in total. have.

Pins 7 to 9 correspond to inputs of the current detector 180 that detects the amount of current applied to the color-specific lighting lamps, and prevents the occurrence of overcurrent above the set upper limit.

At this time, the HR-1000 controls the amount of current applied to the red, green, and blue LEDs, respectively, so that pin 7 monitors the amount of current of the red LED, pin 8 of the green LED, and pin 9 of the blue LED.

For example, the current detector 180 receives a signal indicating that the amount of current of the lighting lamp for each color is an overcurrent exceeding a predetermined reference (for example, 700 mA), and notifies the processor 110, and the processor 110 controls the amount of current of the lighting lamp. do.

The peripheral circuit of the current detector 180 is implemented as a resistive element whose potential changes according to the amount of current of the lighting lamp as shown in FIG. 4, and may be configured to change a predetermined reference when another resistance value is applied.

Meanwhile, the current detector 180 may be an IO block that recognizes an overcurrent generation as a "low" or "high" signal according to a peripheral circuit, or an ADC that recognizes an analog signal by comparing the potential of an input analog signal with a preset reference. It may be implemented.

Pin 10 corresponds to the ADC 140 for analog-to-digital conversion of the input potential, HR-1000 is the ADC 140 to control the amount of current by comparing the potential according to the temperature transmitted by the temperature sensor 251 with a preset reference Use

The HR-1000 supports 10-bit ADCs 140, enabling sophisticated temperature detection.

Pin 11 corresponds to IO block 150, which can be used as an input or output, HR-1000 receives the signal of the potential divided by day or night from the illumination sensor 252 to automatically turn on and off the lamp IO block 150 is used for this purpose.

The user can set the operation of the lighting lamp control system stored in the EEPROM via the remote device to stand-alone which automatically turns on / off the lighting lamp.

That is, when set to stand-alone, the driving of the lighting lamp control system is automatically started at night, and the driving of the lighting lamp system is automatically terminated at daytime.

Pins 12 to 15 are inputs of the illumination lamp driver 170 and pins 16 to 19 are outputs of the illumination lamp driver 170.

Pins 12 and 16 are the input and output of the illumination lamp driver 170 to drive the red LED, pins 13 and 17 and pins 15 and 18 are the input and output of the illumination lamp driver 170 to drive the green LED, pin 15 And pin 19 are input and output of the illumination lamp driver 170 for driving the blue LED.

Here, the reason for assigning two pins to the green LED is that the brightness of the green LED is only about 1/2 of that of the red and blue LEDs, so that the balance between the red and blue LEDs is applied by applying a double transistor and a green LED. To match.

The HR-1000 used four high power transistor arrays as the lighting lamp driver 170.

That is, pins 12 to 15 correspond to the base terminals of the individual high power transistors, and pins 16 to 19 correspond to the collector terminals of the individual high power transistors.

At this time, since the individual high power transistor drives a plurality of lighting lamps, it is desirable to ensure a maximum current of about 1.0A to 2.0A.

At this time, pins 16 to 19 are applied with the current amplified by the high power transistor, it is necessary to pay attention to the thickness of the pattern and the arrangement of the peripheral elements when designing the PCB.

That is, it is preferable that the pattern is designed as thick as possible in consideration of the amount of current of the LED to which the high power transistor is connected, and the high power transistor and the LED are arranged as close as possible.

The light emitting unit 230 that works with the HR-1000 is composed of 12 (4 x 3 array) red LEDs, 24 (8 x 6 array) green LEDs, and 12 (4 x 3 array) blue LEDs.

Meanwhile, the predetermined reference temperature stored in the EEPROM, the frequency and magnitude of the LED driving signal, the maximum current applied to the LED, whether the stand-alone method is used, the reference illuminance, etc., can be updated through a remote device after being set in the development and mass production stage. It is desirable to.

This is because general electronic products have a certain error in performance. LEDs have a high possibility of degrading performance, especially in accordance with the period of use, so that the efficiency of use is improved by adjusting the frequency of the LED driving signal or the maximum current amount. .

In addition, since the environment in which the lighting lamp control system is applied may vary according to the user, it is to increase the convenience of operation by changing the system setting at the user level.
