Description

TECHNICAL FIELD [0001] The present invention relates to an LED lighting system using a smart driver,

The present invention relates to a system lighting apparatus that uses a color LED as a light source and can control color temperature and brightness according to a surrounding environment or a user's operation through a smart driver and a control unit. More particularly, A smart driver that can reduce the intensity of the power supplied to the LED module or prevent it from being damaged by overheating when the LED module is overheated due to a long lighting time, LED SYSTEM LIGHTING DEVICE,

In addition, the present invention relates to an LED system lighting device using a smart driver that can prevent the degradation of illumination quality due to foreign substances such as dust penetrating into the inside of the cover by enhancing the dustproof property of the LED fluorescent lamp.

LED has many advantages such as low power, semi-permanent life span, and high illumination, and is becoming a popular light source in recent years.

The LED also has the advantage of adjusting the color of the illumination light, that is, the color temperature and the brightness of the illumination, that is, dimming in real time.

As a result, LEDs that have many advantages over conventional fluorescent lamps have a tendency to lower the illuminance gradually for a long time.

All luminaires differ significantly when comparing the initial and long-term illumination.

 LEDs have good heat dissipation and deterioration occurs for a long time even under normal conditions.

For example, in a 37W LED flat panel luminaire, the initial luminous flux was about 3,580 lm, but at the end of three or five years of life, it is common to be less than 3,000 lm.

The phenomenon in which the light flux falls is different depending on the heat dissipation state of the LED lighting apparatus or the place of installation, but the phenomenon of falling quickly occurs as the heat dissipation state becomes weak.

In any case, even a well-designed light fixture is generally used to slow down the total luminous flux for a long time.

So, in order to provide better lighting quality and to increase the replacement cycle (the user will be replaced when the light level is lower than his / her own standard), the LED will be used up to the end of its useful life, .

However, according to the prior art relating to a lighting apparatus using an LED as a light source, the use period of fluorescent lamps such as a fluorescent lamp using an LED, a fluorescent lamp type LED lighting apparatus, and the like are disclosed in U.S. Patent No. 10-0866586 and No. 10-1000726 There is no LED lighting device having a means for preventing the illuminance from being gradually lowered in accordance with the illuminance.

In order to increase the productivity of the LED fluorescent lamp, the cover is slidably assembled to the frame, and the cap is assembled on both sides of the frame-cover assembly in an insertion manner and then tightened with a bolt.

Since the frame, the cover and the cap of the LED fluorescent lamp are assembled and assembled to each other, a tolerance is inevitably required to assemble them to each other, and due to the tolerance, the fine dust in the air is scattered through the inside of the LED fluorescent lamp, Particularly the inner surface of the cover.

Fine dust that has penetrated into the inside of the LED fluorescent lamp is attached to the inner surface of the transparent cover, thereby deteriorating the quality of the illumination irradiated from the LED module.

Therefore, there is a tolerance to assemble the frame, the cover and the cap, but the clearance between the frame, the cover and the cap needs to be sealed so that the fine dust does not penetrate into the interior of the LED housing. That is, it is necessary to enhance the dustproof property of the LED fluorescent lamp.

However, the prior art is not interested in dustproofness.

The present invention has been made in order to overcome the problem that the illumination quality is deteriorated and the replacement cycle is accelerated for a long period of time as the prior art does not pay attention to the problem that the use time of the LED illumination device is gradually increased and the illumination is gradually weakened, As an invention, it is an object of the present invention to provide an LED system lighting device using a smart driver that increases the intensity of power supplied to an LED module as the cumulative lighting time of LEDs increases, Lt; / RTI &

First, an LED system lighting apparatus using a smart driver according to the present invention comprises an LED module 10, an LED fluorescent lamp in which the LED module 10 is incorporated, and a controller for controlling lighting of the LED module 10 .

First, a controller for controlling lighting of the LED module 10 will be described with reference to FIGS. 1 and 2. An LED fluorescent lamp in which the LED module 10 is incorporated will be described with reference to FIGS. 3 to 8. FIG.

As shown in FIGS. 1 and 2,

A surge protection unit 1 for disconnecting a surge included in the input commercial power supply,

A filter unit 2 for removing harmonics such as harmonics included in the input commercial power supply,

A rectifying section 3 for full-wave rectifying a commercial power source that has passed through the surge protection section 1 and the filter section 2,

A transformer T transforming the output power of the rectifying unit 3 to reduce the output power,

A switching unit 7 provided between the rectifying unit 3 and the transformer T for switching the output power of the rectifying unit 3 in a PWM manner so as to improve the power factor and to transform the transformer T, Wow,

A DC unit 4 for converting the output power of the transformer T into a DC power source to generate a power source to be supplied to the LED module 10,

A driver 5 for driving the LED module 10 to control an output power of the direct current unit 4 to adjust color temperature and dimming of light emitted from the LED module 10,

A control unit (6) for controlling the driver according to set data and an externally input command signal and controlling the switching unit (7)

A timer 8 for providing time data to the control unit 6,

A driving power supply unit 9 for converting the output power of the transformer T into a driving power source and supplying the power to the control unit 6 and the timer 8,

A remote control receiving unit (a) for receiving an external command signal from the remote controller and transmitting the external command signal to the controller 6, a wireless communication unit for wirelessly communicating with a wireless terminal (e.g., smart phone) (B) for supporting the programming of the setting data to the control unit.

The surge protection unit 1 includes a fuse F1 for blocking and protecting an input of an AC commercial power supply when an overcurrent is inputted thereto from a commercial power supply and an instantaneous overvoltage via a commercial power supply, And a varistor S1 for clamping and protecting the converter is connected.

The filter unit 2 is connected to the output side of the fuse F1 and the varistor S1 to remove the conductive noise included in the AC commercial power source.

The filter unit 2 includes two line filters LF1 and LF2 on both sides and capacitors C1 and C4 provided on the input and output sides and output sides of the two line filters LF1 and LF2, The midpoint of the two capacitors (C2, C3) is grounded to drain the conductive noise to ground.

The rectifying unit 4 performs a full-wave rectification of the commercial power output from the filter unit 2 and converts it into a pulsed power supply.

The rectifying unit 3 is composed of a bridge diode K1.

The transformer T transforms the pulsating current output from the rectifying unit 3 to output a rated power having improved power factor.

The direct current unit 4 generates a constant voltage (or a constant current) of DC 24 to 48 V and outputs the power generated from the transformer T.

The driver 5 drives the LED module 10 using the output power of the direct current unit 4 and drives the LED module 10 so that the color temperature of the LED module 10 is 3000K to 6000K to emit emotional illumination , And adjusts the illumination brightness of the LED module 10 to a high resolution (2 16) (i.e., fine dimming control).

The timer 8 checks the flow of time in real time and stores the year, month, day, day, hour, minute and second data internally, and automatically converts and processes the leap year until the year 2100 I have.

The control unit (MCU) 6 is a dedicated processor for controlling the controller, and can be programmed by a designer, thereby giving various and smart functions (dimming control, color temperature control, etc.) to the illumination.

The control unit 6 controls the driving of the driver 5 to adjust the color temperature and dimming of the LED module 10 and controls the switching unit 7 to adjust the output power intensity of the transformer T Control the overall control of the controller.

The control unit T receives the time data from the timer 8 and extracts the cumulative lighting time of the LED module 10 (or the elapsed time after the initial installation) using the received time data, As the cumulative lighting time increases, the intensity of the power supplied to the LED module is increased, so that even when the cumulative lighting time of the LED module is increased, it is illuminated with a predetermined illuminance.

As described above, as the use time of the lighting apparatus increases, the illuminance gradually decreases due to deterioration or the like. For example, if the LED is illuminated at 100 lumens after 10 volts of power is supplied at the beginning of the installation, the lamp will be illuminated with 90 lumens of illumination even if 10 volts is supplied over time, Even if 10 volts is supplied, it illuminates with 80 lumens of illumination.

When the actual illuminance is lower than the set illuminance, the illumination quality is deteriorated. When the user recognizes that the illuminance is lowered, the user determines that the user has reached the end of his or her lifetime.

In order to solve the problem that the illumination quality of the LED is lowered and the replacement period of the user is shortened due to the passage of time,

The control unit 6 acquires the time-related data (i.e., the elapsed time after the installation or the cumulative lighting time of the LEDs) from the timer 8, and uses the acquired time data to calculate the intensity To allow the LED to continue to illuminate at the same initial illumination.

The controller 6 receives the data related to time from the timer 8 so that it can utilize the illumination of the LED as a sleep function, a morning call function, a schedule function, and the like.

In other words, if the user sets the time related to various modes in the control unit using a remote controller or a smart phone, the controller 6 controls the illumination of the mode at the set time using the time data transmitted by the timer 8 .

For example, if you set the sleep mode, the LED initially lights up in a warm white color suitable for sleeping. If you warn about 5 to 10 minutes, it turns off, and the morning time starts to illuminate with low illumination 30 minutes before Gradually increase the illumination, and at the end, produce a cool white color. And it would be better if you play sound or music together.

The controller includes a temperature sensor (not shown) for sensing the ambient temperature, and the temperature sensor transmits the sensed temperature to the controller 6.

If the sensed temperature transmitted by the temperature sensor exceeds the reference temperature, the controller determines that there is a danger and reduces or interrupts the intensity of the power supplied to the LED module 10 to overheat the controller or the LED module .
