Description

[0001] LIGHTING SYSTEM FOR USING LED [0002]

In particular, the present invention relates to an illumination system using an LED, in particular, a DC power supply is connected to a rear end of a light breaker of a power distribution box for a household, and DC power output from the DC power supply is supplied to LED lighting installed in a household, And more particularly to a lighting system using an LED that can drive LED lighting without a converter device.

Since a light emitting diode (hereinafter, referred to as LED) converts electric energy into direct light energy, it has a high conversion efficiency to light energy as compared with an incandescent lamp, a fluorescent lamp, and a halogen lamp, . Especially, when LED converts electric energy into light energy, efficiency of about 20% or more can be achieved, so that conversion efficiency can be about 100 times or more as compared with incandescent lamp or fluorescent lamp.

In addition, the LED has a long life span that is semi-permanent. For example, compared to an incandescent lamp, a typical incandescent power consumption is about 100W, while a LED consumes 25W. In addition, the lifespan of an incandescent lamp is about 3,000 hours, while the lifetime of an LED is over 40,000 hours.

And since the light emitted from the LED does not flicker like the light emitted from the fluorescent lamp, the user can feel less fatigue of the eyes. As such, since LEDs have excellent characteristics compared to conventional lighting means, the application range of LEDs has been expanded not only to electronic devices such as various display devices but also to lighting devices.

Unlike conventional fluorescent lamps or incandescent lamps, which are driven by an AC power source, such LED lights are driven by a DC power source, and thus include a converter that converts an AC power supplied from a commercial source to a DC power source. The converter is a major obstacle to emitting the heat generated from the LED to the outside and causes the cost and weight of the LED lighting to increase. In addition, the converter has a problem in that it is difficult to incorporate an on / off function and a dimming function of an illumination by installing an automatic control device in the LED.

This problem is caused by the fact that the price of the LED having a high manufacturing cost is further increased as compared with the fluorescent lamp or incandescent lamp, thereby making it difficult to implement the lighting system using the LED. Therefore, It is required to provide a way to lower the manufacturing cost of the apparatus.

1 is a block diagram illustrating a DC power supply according to a preferred embodiment of the present invention.

Generally, a DC power supply device is a device that outputs an AC power by using an AC power as an input, and is a device capable of variously converting and outputting a desired power source within a certain range. Such a direct current power source device is widely used as a direct current stabilized power source for an electronic communication device such as an electronic calculator, an electronic exchanger, and an OA device. Typically, a SMPS (Swithing Mode Power Supply) or the like is used as a DC power supply device, but the present invention is not limited thereto.

1, a DC power supply 100 according to an exemplary embodiment of the present invention includes an EMI filter rectifier 110, a PFC circuit 120, a PFC control unit 130, a power switching unit 140, a PWM / And includes a PFC control unit 150, a transformer 160, a photocoupler 170, a rectifier and filter 180, a detection circuit 190, a current sharing unit 200, and an OVT 210.

The commercial AC input to the DC power supply 100 is supplied through a noise filter circuit such as an EMI filter rectifier 110 for preventing various kinds of high frequency noises after passing through various protection circuits, And then supplied to the intermittent circuit such as the power switching unit 140. [

The intermittent current by the switching element controlled by the control circuit such as the PWM / PFC control unit 150 such as the ON or OFF time and the fixed ON time controlled in the secondary circuit is supplied to the secondary circuit through the transformer 160 And rectified and smoothed through a rectifier and a filter 180 or the like to produce a DC voltage of the secondary circuit.

The secondary voltage is compared with the reference voltage, and the error is transmitted to the primary PWM / PFC controller 150 through the photocoupler 170, and error correction for the secondary load current and the primary AC voltage variation To maintain a constant secondary voltage.

The output capacity of the normal direct current power supply device 100 can be adjusted by the current capacity of the primary circuit and the voltage and current capacity of the secondary circuit. The contents of the primary power switching unit 140, the primary smoothing circuit including the transformer 160, the noise filter, and the voltage and current capacity of the secondary rectifying circuit.

2 is a block diagram illustrating a configuration of an illumination system using an LED according to an exemplary embodiment of the present invention.

Referring to FIG. 2, an illumination system using LEDs according to an embodiment of the present invention includes a power distribution box 10, a DC power supply 100, a DC / DC converter 300, at least one LED lighting 400, , And at least one switch (500).

Generally, when the 220 V AC power is input into the household through the distribution box 10, the DC power supply 100 formed at the rear end of the generation distribution box 10 is output through the distribution box 10 The AC power is converted into the DC power of the safe voltage range.

The safety voltage is a voltage of about 50 V, which means that the user can minimize the risk of electric shock.

The DC power source that has been reduced in the safety voltage range through the DC power supply 100 is reduced in voltage to a voltage within a range for driving the LED lighting 400 through at least one DC / DC converter 300. As described later, since the LED lighting 400 is driven at a voltage of about 2.6 to 3.2 V per chip, the voltage of the DC power source is driven by the DC / DC converter 300 It can be decompressed to a level voltage.

Meanwhile, according to the embodiment, the 220V AC power input into the household can be converted to the safety voltage level in place of or in addition to the DC power supply apparatus 100, A rectifying circuit (not shown) may be formed to convert the AC power source into a DC power source.

However, since the conventional LED lighting device 400 has a built-in converter for converting the AC power supplied to the household into the DC power, the manufacturing cost is high and the weight of the LED lighting device is increased. However, The LED lighting 400 according to the embodiment does not incorporate a separate converter for converting the AC power into the DC power because the AC power is converted into the DC power using the DC power supply 100 formed at the front end.

When the LED lighting device 400 is directly connected to the DC power source as described above, an automatic control device (not shown) can be built in the LED lighting device 400 to control on / off the LED lighting device 400 DIMMING control can be enabled. The dimming means changing the light flux of a light source in a lighting fixture, mainly used for a dramatic effect of a lighting environment, for changing atmosphere, or for energy saving.

In particular, in this case, the LED lights 400 may be grouped so that on / off control and dimming control may be performed for each group, and the user can control the LED lighting 400 more conveniently at a time. For example, a user can group ON / OFF control and dimming control at once by grouping the LED lighting installed in the room and the LED lighting installed in the living room.

Further, the LED illumination 400 can be controlled on / off and dimmed using an application installed in the smart terminal device.

The smart terminal device is a digital device including a function of enabling communication after being connected to a communication network, and is a digital device such as a personal computer (e.g., a tablet computer, a notebook computer, etc.), a PDA, a web pad, And can be adopted as a smart terminal device according to the present invention as long as it is a portable digital device having a computing ability by mounting a microprocessor.
