Description

[0001] Apparatus for controlling light power supply [0002]

The present invention relates to an illumination lamp power supply control device, and more particularly, to an illumination lamp power supply control device that provides a stable power supply for driving an illumination lamp.

Recently, in Korea, natural disasters are increasing due to frequent stoppages of nuclear power plants and subtropicalization of the Korean peninsula. As the weather changes beyond the data values of recent decades, it is impossible to predict and the electricity supply and demand is disrupted. For example, the blast, such as BLACK OUT, is approaching and becoming a topic of many people.

In particular, the time when the use of incandescent lamps is prohibited worldwide is coming, and LED lighting lamps are rapidly spreading in accordance with the global trend of the future. However, the development and manufacture of LED lighting has increased, but the alternative to efficiently manage and utilize LED lighting is still in its infancy.

Other objects, features, and operational advantages of the present invention, including its effects and advantages, will become more apparent from the description of the preferred embodiments.

FIG. 1 is a block diagram of an illumination power supply control apparatus according to an embodiment of the present invention. FIG. 2 is a circuit diagram showing a DC / FIG. 3 is a view illustrating a state in which the battery voltage in the battery unit is supplied to the voltage-up unit when the battery is in the power-off state according to the embodiment of the present invention.

Hereinafter, an LED illumination lamp 20 made of a light emitting diode (LED) will be described as an example of an illumination lamp. However, in addition to the LED lighting lamp described above, the lighting lamp power control device of the present invention may be applied to various lighting lamps such as OLED lighting lamps, lamps, and the like.

Generally, in the case of the LED lighting lamp 20, a small-sized SMPS power supply is built in to drive the LED. Switching Mode Power Supply (SMPS) is a constant voltage supply unit that converts AC voltage (AC voltage) of 220 [V] / 60 [Hz] into DC voltage (AC voltage). The illumination lamp power control device of the embodiment of the present invention is provided with a power supply control device for illumination lamps separately in the switchboard without providing the SMPS inside the LED lamps 20 to supply the constant voltage to the illumination lamps. In particular, the illumination lamp power control device of the present invention performs switching to supply an external AC voltage to the illumination lamp as a converted DC voltage, or to supply a battery voltage charged in the battery by a power failure or a user input to the illumination lamp.

To this end, the illumination lamp power control device includes an AC / DC conversion unit 110, an electrostatic detection unit 120, a battery unit 130, a voltage booster unit 150, and a control unit 160.

The AC / DC converter 110 converts an AC voltage (AC voltage) supplied from an external power source 10 such as 220 [V] / 60 [Hz] to a DC voltage (DC voltage) and outputs the DC voltage. The AC / DC conversion unit 110 converts an AC voltage (alternating voltage) of 220 [V] / 60 [Hz] into a DC voltage (alternating voltage).

The AC sensing unit 120 determines whether an AC voltage is input to the AC / DC converter 110 and outputs a status signal. The electrostatic detecting unit 120 employs a voltage sensor to monitor the AC voltage between the external power supply 10 and the AC / DC converter 110. [ That is, whether or not the AC voltage is input to the AC / DC converter 110 is monitored to output a steady state signal when the AC voltage is equal to or higher than a preset reference value. When the AC voltage is lower than a preset reference value, do. For example, when the reference value is set to 215 [V], a steady state signal is outputted when the AC voltage inputted from the external power supply 10 is 210 [V] or more, and the AC voltage inputted from the external power supply 10 is 210 [V], a power failure status signal is output.

The battery unit 130 receives and charges the DC voltage output from the AC / DC converter 110, and outputs a voltage charged in the battery unit 130 as a battery voltage at the time of discharging. The battery unit 130 is charged when one end is connected to the AC / DC converter 110 and the other end is connected to the ground, as shown in FIG. Conversely, when one end is connected to the AC / DC converter 110 and the other end is connected to the voltage booster 150 as shown in FIG. 3, the charged battery voltage is supplied to the voltage booster 150.

The battery unit 130 serves as a battery or a secondary battery, and converts the battery into electrical energy by a chemical action occurring in the battery. Meanwhile, the battery unit 130 may be implemented as a lithium ion battery, a lithium polymer battery, or the like. Lithium-ion battery (Li-ion battery) is a type of secondary battery, in which lithium ions move from the cathode to the anode during the discharge process. At the time of charging, lithium ions move from the anode to the cathode again and find their place. A lithium ion battery is different from a lithium battery, which is a primary cell that can not be charged and reused, and is different from a lithium ion polymer battery using a solid polymer as an electrolyte. Lithium-ion batteries have high energy density and no memory effect, and they are often used in portable electronic devices because they are less likely to discharge naturally when not in use. In addition, the lithium polymer battery is made by polymerizing a polymer composed of polyethylene glycol or polyvinylidene fluoride by electrolytic solution, and is essentially the same as a lithium ion battery. However, lithium polymer batteries have the advantage that the electrolyte does not leach out because the electrolyte is in a quasi-solid state. It is considerably lighter than other types of batteries and has very little memory effect.

The boosting unit 150 boosts the DC voltage or the battery voltage and outputs the boosted voltage to the LED illumination lamp 20 as a drive voltage. The voltage step-up unit 150 is a power supply converting device for converting the voltage so as to drive the LED lighting lamp 20. Since the voltage to be driven is different for each LED lighting lamp 20, DC], 12V [DC], and 24V [DC].

The switching unit 140 performs switching to electrically connect the AC / DC converter 110 and the booster 150 or electrically connect the battery 130 and the booster 150 to each other. That is, in the case where the converted DC voltage of the external power supply 10 supplied from the outside is supplied from the AC / DC converter 110 to the booster 150, the AC / DC converter 110 and the booster 150, When the voltage supplied from the battery unit 130 is supplied to the voltage booster unit 150 during a power failure or an emergency, the battery unit 130 and the voltage booster unit 150 are electrically connected to each other Switching. For reference, the switching unit 140 may be implemented through a relay switch or the like.

The control unit 160 controls the switching unit 140 according to a status signal output from the power failure detection unit 120. The control unit 160 controls the DC voltage output from the AC / DC conversion unit 110 or the DC voltage output from the battery unit 130, Voltage to the voltage-boosting unit 150. The switching unit 140 controls the switching unit 140 to supply the voltage-boosting unit 150 with a voltage. That is, when the normal state signal is outputted from the electrostatic sensor 120, the switching unit 140 is electrically connected to the AC / DC converter 110 and the voltage booster 150 as shown in FIG. 2 So that the DC voltage is supplied to the voltage boosting unit 150. At this time, the battery unit 130 is electrically connected to the ground (GND) to charge the battery unit 130.

3, the control unit 140 controls the switching unit 140 to electrically connect the battery unit 130 and the voltage step-up unit 150 to each other, So that the voltage is supplied to the voltage boosting unit 150. Accordingly, the AC power source is suitably cut off during the power failure, and the LED lighting lamp 20 can be controlled by utilizing the battery unit 130, thereby saving electricity costs and preparing for power failure.

As described above, the controller 160 can turn off the external AC power during the power outage and turn on the LED illumination lamp 20 by utilizing the battery voltage of the battery unit 130. In the event of an emergency, The LED lighting lamp 20 may be turned on by turning off the external AC power and utilizing the battery voltage of the battery unit 130. [

The control unit 160 receives the user operation input 30 according to the user's operation and switches the AC / DC conversion unit 110 and the voltage step-up unit 150 to be electrically connected to each other according to the user- To supply the DC voltage to the voltage booster 150 or to switch the battery 130 and the voltage booster 150 to be electrically connected to supply the battery voltage to the voltage booster 150. That is, a separate user input interface (not shown) is provided for this purpose. The user can input various commands through the user input interface. Such an input interface can have various user interfaces (UI) such as a keypad of a combination of numbers, symbols, and English / Korean, and a touch screen. In particular, a GUI (Graphic User Interface) . ≪ / RTI >

The user operation input 30 may be in various forms, for example, receiving a remote operation input from a user via a network, or receiving an operation input of a scheduling timing. The control unit 160 may perform switching control that is remotely input from a user through a network and switching control according to a scheduling timing input from a user.

Hereinafter, switching control to be remotely input from a user via a network and switching control according to a scheduling timing input from a user will be described in order.

First, receiving a remote operation input from a user via a network is a remote operation input through a network from a user at home or outside the building. Even if the user is outside the house, the user can operate the LED lighting lamp 20 to turn off the external power source 10 and utilize the battery voltage of the battery unit 130 by operating the user through the network. If the battery unit 130 is not charged even though there is a light emitting operation of the LED lighting lamp 20 through the battery voltage, the controller 160 notifies the user of the fact through the network, The switching control is performed so that the light emission by the DC voltage converted from the external voltage is performed.

For reference, such a network may be a wired communication method such as Ethernet, universal serial bus, IEEE 1394, serial communication, and parallel communication, A Bluetooth, a home radio frequency (RF), and a wireless LAN may be used. In addition, it will be able to receive remote operation input from the user's cellular phone by utilizing the wireless mobile communication network such as 3G and 4G. Therefore, although not shown separately in FIGS. 1 to 3, the illumination lamp power control device must include a network processing module capable of processing a communication protocol of the network.

On the other hand, switching control according to a scheduling timing input from a user will be described. Receives the scheduling timing from the user so as to emit the LED illumination light 20 with the battery voltage only for a predetermined time, and performs switching control according to the inputted scheduling timing. Since the battery unit 130 is discharged when the battery unit 130 is charged, the battery unit 130 has a predetermined time to charge the battery unit 130 and uses the charged battery voltage for light emission of the LED lighting unit 20. For example, switching control can be set so that charging and discharging are alternately performed every four hours. Thus, by controlling the light emission of the LED lighting lamp 20 through the battery voltage, it is possible to save electric power costs.

In particular, even if the same external power is supplied, the electricity cost varies depending on the time zone. In other words, electric power supplied from KEPCO is cheaper than the daytime hours, and the electricity peak is introduced from 12:00 to 3:00 pm during the daytime, so the electricity cost is the most expensive during that time. Accordingly, the LED lighting lamp 20 can be illuminated as a charged battery voltage at a time of expensive electricity bill according to a user's scheduling timing operation input, and the LED lighting lamp 20 can be realized as a DC voltage of external power at a time of low electricity cost .

For this, the controller 160, which performs switching control according to the scheduling timing, electrically connects the AC / DC converter 110 and the voltage booster 150 at midnight to 6:00 am, 150 and may control switching to supply the battery voltage to the voltage step-up unit 150 by electrically connecting the battery unit 130 and the voltage step-up unit 150 during a period from noon to 6:00 pm .

FIG. 4 is a flowchart illustrating a lighting power supply control process according to an embodiment of the present invention.

First, an AC voltage, which is an external voltage supplied from the outside, is converted into a DC voltage and outputted (S401). The output DC voltage charges the battery (S402).

And continuously monitors whether an AC voltage which is an external voltage is applied (S403). As a result of the monitoring, if the external voltage AC voltage is inputted, the normal state signal is outputted (S411). If the external AC voltage is not inputted, the power failure state signal is outputted (S421).

When a steady state signal is output (S411), the DC voltage is stepped up and supplied to the LED illuminating lamp 20 to switch on the LED illuminating lamp 20 to emit light (S412). On the other hand, if the power failure state signal is output (S421), the battery unit 130 is controlled to be discharged so as to discharge the battery voltage to the LED lighting lamp 20 to emit the LED lighting lamp 20 (S422).

The embodiments of the present invention described above are selected and presented in order to assist those of ordinary skill in the art from among various possible examples. The technical idea of the present invention is not necessarily limited to or limited to these embodiments And various changes, modifications, and equivalents may be made without departing from the spirit and scope of the present invention.
