Description

TECHNICAL FIELD [0001] The present invention relates to a smart dimming control apparatus and method for an LED streetlight,

The present invention relates to a smart dimming control apparatus and method for an LED streetlight.

With the exponential growth of LED lighting, a variety of integrated circuit devices are emerging that supply regulated power to LEDs. DC power supplies with high power consumption have long been the standard, but energy issues are becoming a serious issue and are now being replaced by switching mode LED drivers. Currently, it requires precise control of constant current in a wide range of fields, from flashlight to the display board of the stadium. In most cases, the ability to adjust the LED output intensity momentarily, or dimming control, is required.

In recent years, street lights and security lights have been changed to LED lights. LED lights used for street lights and security lights are characterized by their power consumption of 180 ~ 240W depending on their supply voltage conditions. If the LED lighting is not used at the set rated power, it may affect the lifetime of the LED lighting if it is repeated over a long period of time. For this reason, dimming control, which can provide precise and rated power, is indispensable to streetlights and security lights.

However, since the dimming control of the LED lighting currently developed is mainly for controlling the illuminance of the LED illumination based on the illuminance received from the illuminance sensor, there is a lot of malfunction due to dust around the illuminance sensor, There are disadvantages that are not uniform.

2 is a block diagram illustrating an internal configuration of a dimming controller 120 according to an embodiment of the present invention.

2, the dimming controller 120 includes a connector 210, a communication unit 220, a power supply unit 230, a storage unit 240, a control unit 250, a temperature sensor 255, A second protection unit 270, and the like.

For example, when the time dimming control amount as shown in Table 1 below is stored in the storage unit 240 for each section in which the operation time period (for example, 12 hours) of the LED lighting apparatus 100 is divided into 12 sections (time units) Applies a switching signal to the power supply unit 230 so that the LED lighting apparatus 100 dims at a brightness of 100% for the first 3 hours after driving, and then the LED lighting apparatus 100 displays a brightness of 70% A switching signal is applied to the power supply 230 for dimming and a switching signal is applied to the power supply 230 so that the LED illumination device 100 dims at 50% brightness for 5 hours, and brightness of 70% So that the power supply 230 can be supplied with a switching signal.

[Table 1]

On the other hand, when the dimming control amounts of the four sections obtained by dividing the operation time period of the LED lighting apparatus 100 of the summer and winter season into four sections as shown in Table 2 below are stored in the storage section 240, It is possible to apply different switching signals by dividing the operation time period of 14 hours into four periods in the summer season. Specifically, the controller 250 controls the power supply unit 230 to supply power from 18 o'clock, and then controls the LED lighting apparatus 100 so that the LED lighting apparatus 100 dims to 100% brightness during a first period (18 o'clock to 22 o'clock) A switching signal is applied to the supply unit 230 and a switching signal is applied to the power supply unit 230 so that the LED lighting apparatus 100 dims at a brightness of 70% The LED lighting apparatus 100 is switched to the 50% state in the fourth period 03 to 06 after the switching signal is applied to the power supply unit 230 so that the LED lighting apparatus 100 dims at 30% A switching signal is applied to the power supply unit 230 so as to dim the brightness of the power supply unit 230 and the power supply unit 230 may be controlled so that the power supply is cut off at 6:00.

Specifically, the controller 250 controls the power supply unit 230 to supply power from 17 o'clock, and then controls the LED lighting apparatus 100 to dim to 100% brightness during the first period (17 o'clock to 22 o'clock) A switching signal is applied to the supply unit 230 and a switching signal is applied to the power supply unit 230 so that the LED lighting apparatus 100 dims at a brightness of 70% The LED lighting apparatus 100 is switched to 50% in the fourth period 03 to 07 after the switching signal is applied to the power supply unit 230 so that the LED lighting apparatus 100 dims at 30% The switching signal is applied to the power supply unit 230 so as to dim the brightness of the power supply unit 230 and the power supply unit 230 may be controlled so that the supply of power is interrupted at 7:00.

[Table 2]

The power supply unit 230 controls the power supplied to the LED module 110 through the switching operation according to each switching signal to control the intensity of the LED module 110 to control the dimming amount of the LED lighting unit 100 can do.

Meanwhile, the control unit 250 may adjust the amount of dimming of the LED lighting apparatus 100 through comparison between the sensing signal of the temperature sensor 255 sensing the temperature of the power supply unit 230 and a predetermined threshold temperature. More specifically, when the temperature sensed by the temperature sensor 255 is 60 degrees or more, the control unit 250 provides a switching signal to the power supply unit 230 so that the LED lighting apparatus 100 dims to 50% The power supply unit 230 can be controlled by the dimming control amount stored in the storage unit 240 when the temperature sensed by the sensor 255 falls to 60 degrees or less.

The first protection unit 260 limits the overvoltage input through the connector 210 and may supply the stabilized power to the power supply unit 230 by allowing the surge current to flow to another path, that is, the ground terminal. Specifically, although the first protection portion 260 exhibits a large impedance when there is no surge, it may be a voltage switching element in which the impedance is sharply reduced with respect to the voltage surge. Examples of the voltage switching device include, but are not limited to, a discharge gap, a gas discharge tube (GDT), a thyristor (silicon controlled rectifier), and a triac.

The second protection unit 270 is connected between the LED module 110 and the power supply unit 230 to limit the overvoltage input through the power supply unit 230 and to allow the surge current to flow to another path, So that stable power can be supplied to the module 110.
