Recently, illumination using an LED lamp that is excellent in energy saving effect and being environmentally friendly has attracted attention. The LED light has a long lifetime, high luminance, low power consumption, and thus has an energy saving effect and an effect of reducing CO ₂ Etc. are well known.

In addition, LED lamps are regarded as means for replacing traditional lightings such as incandescent lamps, halogen lamps, and the like, which are embodied by fluorescent lamps.

The above-mentioned LED lamp is mainly used for illuminating the room and has a high energy efficiency and brightness, and a rod type is mainly used. The color is adjusted by using R, G, B of the LED and is mainly used for daylight, main white, silver white, Color and the like are used.

That is, it is common to use an incandescent lamp or a fluorescent lamp as an illumination device for illuminating the surroundings. Recently, since it can perform various colors and has a long lifetime and low electric consumption, LED (Light Emitting Diode) lamp Have been widely developed and used.

An LED (Light Emitting Diode) is a semiconductor device that converts electric energy into light, and utilizes a light emitting phenomenon (electroluminescence) that occurs when a voltage is applied to a semiconductor.

The LEDs originated from the emission observation of silicon carbide crystals in 1923, and since the high efficiency of light emission in the gallium arsenide p-n junction was found in 1923, the research has been actively carried out and has been put to practical use since the late 1960s.

In addition, the LED uses a very small chip surrounded by an epoxy resin enclosure, so that it can be downsized. It is a power-saving type that operates at 2 to 3.6 V and 0.02 to 0.03 A based on one LED and consumes less than 0.1 W of power, It can be used for up to 100,000 hours with less damage, and it converts most energy into light, which has the advantage of emitting high efficiency and low heat.

Among the conventional lighting apparatuses using LED lamps, an LED lighting apparatus designed to replace a conventional fluorescent lamp is disclosed in Patent Registration No. 10-866586.

1 is a perspective view of a fluorescent light substituting LED lighting device according to the related art.

Referring to FIG. 1, a fluorescent lamp replacement LED illumination device according to the related art includes a main body 1 including a hemispherical base 1a and an extension portion 1b bent inward from both ends of the base 1a. A heat radiating blade portion 2 formed along the longitudinal direction inside the base 1a of the main body 1 for increasing the heat radiation area to increase the heat radiation efficiency; A fixing part 3 including a plate 3a mounted on an extension of the base 1a and a receiving protrusion 3b connected to both sides of the plate 3a; An LED module 4 sandwiched between the receiving projections 3b of the fixing part 3 and composed of a PCB 4b on which a plurality of LEDs 4a are mounted; A cap which covers the main body 1 and has a hemispherical shape and which has a thickness smaller than that of the upper center to increase the amount of light radiated to both sides of the main body 1 to expand the directivity angle of light emitted from the LED module 5); An insertion portion 6 is formed at the upper end of the main body 1 and a corresponding insertion portion 7 is formed at the lower end of the cap 5 to be coupled to the insertion portion 6, A detachment means (not shown) for inserting and detaching the body (1) and the cap (5) by inserting the insertion portion (6) and the corresponding insertion portion (7) 8); And a fixed cover (9) for fixedly coupling both ends of the body (1) and the cap (5) after coupling.

In addition, the color of the LED lamp is provided with a separate adjusting device to adjust brightness and color for brightness.

FIG. 2 is a schematic diagram showing an LED illumination for adjusting the illuminance. As shown in FIG. 2, the illumination switch 4 used in a conventional incandescent lamp or a fluorescent lamp, as shown in FIG. , The illumination switch 3 and the socket 2 are connected to the illumination control switch 5 and the illumination control wiring 6 and the LED lamp 1 is connected to the control device 7 for controlling the illuminance of the LED illumination, .

That is, the light switch 1 is turned on / off using the light switch 4, and the light intensity of the LED lamp 1 is adjusted using the light intensity control switch 4. Then, the controller 7 receives the ON / OFF control of the illumination switch 4 and the illumination control of the illumination control switch 7 to drive the LED lamp 1.

Such conventional illumination controllable LED illumination requires additional wiring work separately from the existing illumination wiring 12, and additional switches must be installed so that installation is complicated and costly.

In addition, since the conventional technique has a structure in which the color is controlled by the illuminance switch 7 by shadows, the white LED or the bulb color LED can not be tightened at the same time so that natural light can not be irradiated. There is a problem in that the appearance is not reduced and the irradiated light is limited so that it is restricted in use in a wide place where the intensity of light is large and the high heat emitted from the LED is not efficiently dissipated and the lifetime of the LED lamp is lowered .

In addition, such a lighting system has a problem in that it is impossible to design a function for informing an external notification function in case of an emergency.

In other words, there is a case that when the person goes out for a vacation or a long time, the lighting lamp is turned on in order to psychologically block the penetration of the outside thief, but there is no change of the lighting lamp, .

In addition, there was no concept of lighting control to warn when an uninvited person infiltrated an empty house, and to inform the outside that an emergency occurred in the house.

In addition, there was a monotonous problem because it outputs light of one color.

Hereinafter, various conventional technologies will be described in detail as follows.

The LED illumination device according to an embodiment of the present invention includes a circuit board 10, a daylight-colored LED lamp 20, a full-color LED lamp 30, and a cover 40.

The circuit board 10 supports the LED lamps 20 and 30 and is formed of a conventional PCB substrate.

The LED lamps 20 and 30 are mounted on the front surface of the circuit board 10 at predetermined intervals so as to emit light when power is supplied thereto.

That is, the lead wires of the LED lamps 20 and 30 pass through the circuit board 10 and are mounted on the rear surface of the circuit board 10 by soldering 21 or the like.

The cover 40 protects the LED lamps 20 and 30 and transmits light radiated from the LED lamps 20 and 30 so as to be able to receive the circuit board 10 therein do.

3, the present invention can be basically composed of a switch for a second lamp, two converters, and two LED groups as shown in Fig. 3. In addition, the first switch and the one converter, As shown in FIG.

The most important feature of the present invention is that various emergency sensors are provided and two LED groups are operated according to the sensor.

5, 6, and 7, the present invention further includes a gas sensing sensor 50 and an ultrasonic sensor 60. The gas sensing sensor 50 and the ultrasonic sensor 60 are connected to each other, The LED lamp 20 and the bulb color LED lamp 30 are alternately turned on when gas is detected and when a person is detected in the vacant mode, LED lamps are alternately turned on.

That is, the present invention distinguishes between the passive mode switch 1 and the vacant mode switch 2. When the passive mode switch 1 is switched, the user can turn on either the daylight LED lamp or the bulb color LED lamp as needed Otherwise, all of the daylight-colored LED lamp 20 and the full-color LED lamp 30 are turned on.

When the empty house mode switch 2 is operated, it is sensed whether a person is present in the ultrasonic sensor 60. If a person is detected by the ultrasonic sensor 60 during the empty mode operation, And alternately outputs the color LED lamps 30.

That is, when an emergency occurs in the house, the light bulb is alternately turned on, so it is possible to recognize the emergency even outside the house, so that it is easy to report the emergency situation to the police or notify the security office.

In this case, if the user does not operate the manual mode switch 1 to turn off the illuminating lamp, the control unit automatically turns off the power source automatic returning circuit unit 100 So that the illumination lamps 20 and 30 are continuously turned on to induce the gas discharge to be processed quickly without delay.

In other words, if gas is ignited without knowing whether it is present in the house, a safety accident such as explosion may occur, and it is necessary to keep the ignition state before the danger of gas completely disappears and to induce quick action. To prevent ignition of the gas, ignition lamps should be lit alternately as long as gas is detected.

In addition, according to the present invention, even when a person is sensed in an empty house mode, the state of being alternately turned on is maintained. At this time, if the intruder gets out of the house, the lighting of the nightlight is stopped after a certain period of time. When the manual mode switch 1 is operated to turn off the illumination lamps 20 and 30, the operation of the manual mode switch 1 is interrupted to maintain the on-state, thereby notifying the outside that there is an intruder, To minimize the time it takes to stay at home.

That is, if the intruder is continuously sensed by the ultrasonic sensor 60, the present invention disables the passive mode switch 1 even when the passive mode switch 1 is operated.

The configuration of the power supply automatic return circuit unit 100 of the present invention is as follows.

The power source holding unit 118 is connected to the power source unit.

The power source unit 101 is installed to supply a necessary voltage by connecting a plurality of dry batteries or mercury batteries in series.

The gas sensing sensor signal input unit 102 is connected to a power source unit and switches the power source when gas is detected.

The ultrasound sensor signal input unit 102a is connected to a power source, and when a person is detected, the power source is switched.

The oscillation transformer 103 is supplied with electricity when the power supply unit is turned on, and outputs the boosted AC current.

The switching unit 108 for relay operation is connected to the output terminal of the oscillation transformer and is turned on by electrical supply.

The relay switch 107 is installed at an output terminal of the relay operation switching unit 108 and generates a magnetic force.

The first circuit connection switch sw1 performs a function of energizing the circuit by pulling the iron piece by the relay switch.

The lighting switch SW2 is used to induce the operation of the illumination lamp by supplying power to the illumination lamp operation control unit as the iron wire is pulled by the relay switch.

The power supply switching unit 118 is connected to the first circuit connection switch and the base stage, the emitter stage and the collector stage are connected to the oscillation transformer and the switching unit for relay operation, and the iron wire is pulled by the operation of the relay switch, The first circuit connecting switch is interlocked with the first circuit connecting switch so that the closed circuit is broken and the switching is turned off and the switching unit for relay operation is turned on The relay switch is turned on so that the first circuit connecting switch and the illumination lamp power switch are turned on.

Further, according to the present invention, when the iron piece is operated to illuminate the lighting lamp, the lighting lamp is kept lit even if the power supply is not maintained separately, and the operation of the lighting lamp is stopped only when the user lifts the iron piece with the manual switch. If the passive switch is operated without the disappearance of the intruder or the intruder is not disappeared, the switching part for relay operation is automatically supplied with the power to return the iron piece to continuously output the control signal for lighting the lighting lamp, And the power supply is maintained before the intruder disappears.

That is, the present invention further includes a circuit-operating iron piece 131, a lighting-purpose iron piece 132, a spring 133, a permanent magnet 134, and a passive mode switch 1.

The circuit-operating iron piece 131 is brought into contact with the first circuit connecting switch to turn on the switch for power supply of the gas detection or intruder detection control unit.

The lighting-purpose operating wire 132 is designed to operate in conjunction with the circuit-operating wire. When the wire for circuit operation is turned on, the illumination switch 132 is turned on to turn on the lighting lamp.

The elastic spring 133 is provided between the first circuit connection switch and the circuit operation wire so that the first circuit connection switch and the circuit operation wire are always kept in an off state during non-operation.

The permanent magnet (134) is installed at one end of the first circuit connection switch. When the first circuit connection switch is switched by pulling the wire for circuit operation at the time of operation of the relay switch, the circuit for operating the circuit is attached so that, The ON state of the switching unit for power supply maintenance is maintained.

The manual mode switch 1 is coupled to a circuit for operating circuit and an operation lamp for operation of a lamp. When the user operates the lamp for turning off the operation of the lamp, Stopping the lights will no longer work.

Hereinafter, the operation of the illumination lamp power automatic return circuit unit 100 will be described.

First, when the gas sensor signal input unit 102 or the ultrasonic sensor signal input unit 102a is turned on, DC power is connected to the oscillation transformer, and a high voltage is applied to the secondary side of the oscillation transformer.

The power source induced on the secondary side becomes a DC power source of a half wave through a rectifying diode, and this half wave DC power source becomes a more stable DC power source due to the charging and discharging action of the condenser.

This DC power source is applied to the anode terminal of the thyristor through the coil of the relay switch 107, while the DC power source charges the capacitor through the resistor. The raised voltage triggers the switching unit 108 for relay operation while passing through the diode, so that the node node and the cathode node are switched so that the operation of the relay switch is performed, The circuit connecting switch sw1 and the illumination lamp power switch sw2 are turned on so that the illumination lamp operation control unit 140 is powered and the illumination lamps 20 and 30 operate.

When the first circuit connection switch sw1 is activated, a power source for directing the closed circuit to the emitter end and the collector end of the power source holding switching unit 118 while the base end of the power source holding switching unit 118 is activated, Off.

That is, the voltage between the resistor 109 and the capacitor 110 is passed through the diode 120 to flow between the emitter terminal and the collector terminal of the power supply switching unit 118, and the resistance between the resistor by the bypass and the capacitor When the voltage between the resistor and the capacitor is lowered, the trigger signal to the switching unit for relay operation 108 is stopped, so that the node unit and the tail unit are turned off and the current flows to the relay switch 107 So that the power supply is continuously stopped for switching.

Of course, at this time, since the circuit-operating iron piece 131 is attached by the permanent magnet 134 to maintain the switching operation of the first circuit connecting switch sw1 and the illumination lamp power switch sw2, And the lighting state of the illumination lamp is continuously maintained.

That is, the operation of the relay switch 107 is required only when the first illumination lamp is operated, and thereafter, when the operation of the illumination lamp is started, the operation of the relay switch is no longer required.

On the other hand, if the first circuit connecting switch and the illuminating lamp power switch are turned off using the manual mode switch 1 in the state where the gas is still present or the intruder is present, no current flows in the closed circuit, The bias voltage flowing between the emitter stage and the base stage disappears and the power supply switching unit 118 is turned off.

The switching part for power supply holding is turned off and the bypass voltage between the resistor and the capacitor through the diode 120 disappears, and this voltage is charged in the capacitor 110.

This charged voltage causes a brake-over phenomenon of the die 111. The die signal causes the trigger signal to be output to the switching section for operating the auxiliary switch to move the iron piece, while maintaining the closed circuit and simultaneously output to the lighting operation control section 140 It is possible to continuously operate the illumination lamps 20 and 30 by continuously supplying power to the illumination lamps by returning the power supply.

That is, when the gas is continuously detected by the gas sensor or the ultrasonic sensor 102 or the intruder is continuously detected, even if the user operates the manual switch 1 to turn off the operation of the illumination lamp, It is possible to recognize that the gas still remains due to the illumination of the illumination lamp even if the gas lamp is not completely recognized that the gas lamp has completely disappeared. In addition, since the illumination lamp remains on even when the intruder remains, Lt; / RTI >

If no gas is detected or a person is not detected by the gas sensor signal input unit 102 or the ultrasonic sensor signal input unit 102a, the user manually operates the manual mode switch 1 to turn on the illumination lamp manually .

For reference, the ultrasonic sensor adjusts the distance in advance so that it is operated when a person is standing, and accordingly, when the manual switch is operated while the head is leaning, the illumination lamp can be turned off.
