Description

LED lighting apparatus

The present invention relates to a luminaire using an LED as a light source, the components are detachably coupled to each other in a simple one-touch manner, convenient installation and disassembly, and maintenance,

The body is also easily mounted and disassembled on the ceiling, and when it is mounted on the ceiling, it is firmly supported on the inner surface of the ceiling and there is no risk of unintentionally withdrawing it from the ceiling by accidental external force.

If a surge or overvoltage is included in the commercial power input to the power supply that supplies the driving power to the LED module, the overvoltage breaker blocks it, preventing the power supply and the LED module from being damaged by unstable power, and improving the quality of the lighting. It relates to a raised LED lighting fixture.

Lighting fixtures are installed in houses, offices and factories.

Conventionally, an incandescent lamp or a fluorescent lamp is mainly used as a light source of a lighting fixture, and a fluorescent lamp is mainly used.

However, incandescent and fluorescent lamps consume more power and have a shorter lifetime than lighting efficiency. Fluorescent lamps, in particular, have a serious problem of environmental pollution due to mercury that is discharged during disposal.

Due to these problems, in recent years, power consumption, semi-permanent life, and environmentally friendly LEDs have been spotlighted as light sources around the world.

In addition to the above advantages, LED has the advantage of easy adjustment of illuminance and color adjustment.

The present invention relates to an LED lighting device using the LED having a number of advantages as a light source.

LED luminaires are similar in composition to general fluorescent lamps, as the light source is replaced with LEDs, and the power supply structure that supplies driving power to the LEDs is different.

That is, the LED luminaire generally includes a body having a receiving portion, an LED module (ie, a light source) embedded in the body, a reflector for reflecting light incident from the LED to the front, and a cover covering the front of the body. .

In addition, since LEDs have high brightness and strong straightness, the emitted light causes glare when the light is directly incident to the field of view, so that a cover is generally provided with a diffusion panel that prevents glare by illuminating the LED and illuminates a wide range. do.

 As described above, in the luminaire composed of components such as a body, a light source, a reflector, and a cover, the prior art mainly uses bolts to couple these components to each other. In other words, the bolts were turned with a screwdriver or the like to couple the components together.

As in the prior art, the coupling method of the components through the bolt requires a fastening tool such as a driver, and since the bolt must be reversed, it takes considerable time to couple or disassemble the components.

In addition, the maintenance work of the components is time-consuming and inconvenient, because the time required for the mutual coupling or disassembly of the components.

In addition, even when the body of the lighting fixture is embedded in the ceiling, in the prior art, generally using the anchor bolt, etc., there are similar problems as above, and there is a separate processing process such as hole drilling for fastening the anchor bolt to the ceiling. There is also a need.

In addition, the lighting fixture is provided with a power supply for converting commercial power into a driving power supply to the light source (LED module).

However, commercial AC power is not a stable power source, and its strength is constantly fluctuating. This fluctuation is a fluctuation within the rated range, and most of the fluctuations do not adversely affect the lighting fixtures. Overvoltage (e.g., AC 380V or more) or instantaneous surge overvoltage (e.g., thousands of volts) may occur, and such an overvoltage or surge overvoltage will have a fatal adverse effect on the power supply or light source.

Therefore, it is necessary to protect the lighting fixture by cutting off such overvoltage or surge overvoltage, and many lighting fixtures have introduced a function of blocking the overvoltage.

However, in the prior art, the overvoltage blocking function is mostly embedded in the power supply, and there is a problem in that an interference phenomenon occurs between the overvoltage blocking circuit and the power supply circuit due to the built-in adjacent to each other.

The present invention has been made to solve the problems of the lighting device according to the prior art as described above,

First of all, the purpose of using LED as a light source is to consume less power, have a semi-permanent life, and provide eco-friendly LED lighting fixtures.

In addition, the lifting pins 71 are disposed on one side of the opening portion 73 so that the support rod 77 rotates at the forward and backward rotation of the lifting pins 71 so that the support pins 77 rotate outside the body 10 once. When disposed inside, the support rod 77 is caught by the side wall forming the opening 73 to stop the rotation and to move up and down along the lifting pins 71.

The process of fixedly mounting the lighting fixture to the ceiling by using the mounting means 60 made of the above configuration is as follows.

First, after the support rod 77 is disposed inside the body 10 and then pushes the body 10 into an installation hole (not shown) formed in the ceiling A, the outer surface of the body 10 interferes with this. Since there is no body 10 is easily inserted into the installation hole.

Thereafter, when the lifting pin 71 is rotated forward, the supporting rod 77 is exposed to the outside of the body 10 and is supported on the inner surface of the ceiling (A).

When the support bar 77 is supported on the ceiling inner surface, release the hand holding the body 10, and if the lifting pin 71 continues to rotate forward, the support bar 77 descends to press the ceiling A inner surface. Fix the body 10 to the ceiling.

When removing the body 10 from the ceiling in the reverse order above, the lifting pins 71 are rotated in reverse, so that the support bar 77 is disposed inside the body 10 and then separated from the ceiling.

The overvoltage breaker 200 protects the power supply 100 by blocking an overvoltage or an instantaneous surge overvoltage of a commercial AC power input from the outside.

FIG. 7 is a circuit diagram for the overvoltage breaker, as shown in FIG.

A surge blocking unit 210 for absorbing and blocking a surge of an input commercial AC power source,

A noise removing unit 220 for removing noise of commercial AC power passing through the surge blocking unit;

A switching unit 230 provided at an output terminal and supplying or blocking commercial AC power passing through the noise removing unit to the power supply 100 by an on / off switching operation;

A detection unit 240 for detecting the strength of the AC power output from the noise removing unit;

A control unit 250 which receives the detection signal of the detection unit and controls an on / off switching operation of the switching unit to cut off the overvoltage;

A counter electromotive force blocking unit 270 for blocking back electromotive force introduced into the power supply 60 through the switching unit;

And a starting power supply unit 260 for rectifying and smoothing the output AC power of the noise removing unit to supply the starting power to the switching unit.

The surge blocking unit 210 is connected in parallel to the input terminal, and comprises a varistor (MOV1) and the arrester (A1) connected in series with each other.

A fuse F1 is connected to an input side of the surge interrupter 210 to block an overcurrent when a commercial AC power is applied.

The varistor MOV1 operates as if it is open (OFF) with a high resistance value below a specific voltage, but operates as if it is shorted because the resistance value is lowered above a specific voltage. Thus, when a surge overvoltage is input to the input terminal, it is turned on so that a current can flow.

The arrester A1 absorbs and blocks a current corresponding to a surge overvoltage introduced by the varistor MOV1 turned on. More specifically, the input current is avoided to ground so that the surge overvoltage component of the commercial AC power supply is no longer transmitted to the rear side.

The noise removing unit 32 is connected in parallel to the line filter LF1, the capacitors C1 and C2 connected in parallel to both sides of the line filter LF1, and the output side of the line filter LF1. The point comprises a pair of capacitors C3 and C4 with ground FG.

The line filter LF1 is composed of two coils wound in opposite directions, and cancels noise of the in-phase component from each other and serves as a low pass filter that blocks high frequency components.

Capacitors C1 and C2 connected in parallel to both sides of the line filter LF1 allow the line filter LF1 to remove noise in a wider band.

A pair of capacitors C3 and C4 connected in parallel to the output side of the line filter LF1, more specifically, the capacitor C2 provided on the output side of the line filter LF1, has an intermediate point grounded thereto. Eliminates electromagnetic noise caused by the AC characteristics of commercial AC power supplies.

That is, the pair of capacitors C3 and C4 remove conduction noise, enhance EMC (electromagnetic compatibility), lower EMI (electromagnetic interference) by about 10 dB, and resist EMS (electromagnetic immunity) by more than 10 kV. Have it.

The switching unit 230 is provided at the output terminal of the overvoltage circuit breaker, and is turned on and off by a switching operation to be turned off when the commercial AC power is an overvoltage of a predetermined voltage or higher so that the overvoltage is not supplied to the power supply 100.

In the present invention, when the commercial AC power exceeds AC 380V, the switching unit 230 is turned off to cut off.

In the present invention, although the relay is used as the switching unit 230, a transistor capable of switching operation, a thyristor, a triac, and the like may be used as the switching unit.

As the switching unit 230, the relay includes a driving coil RC and a magnet switch RS turned on and off by an electromagnetic force of the driving coil RC.

The detector 240 includes a current transformer CT1, a bridge diode BD1, a capacitor C8, and a resistor R9.

The current transformer CT1 induces a current flowing in the primary coil provided in the output line to the secondary coil according to the turns ratio, and detects the strength of the AC power output from the noise removing unit 220.

The bridge diode BD1 rectifies the power supplied to the secondary coil of the current transformer CT1. A capacitor C7 is connected between the current transformer CT1 and the bridge diode BD1 to smooth the AC power induced in the secondary coil of the current transformer CT1.

The capacitor C8 connected to the output of the bridge diode BD1 smoothes and directs the power rectified by the bridge diode BD1.

The resistor R9 connected to the output side of the capacitor C8 transfers the power DC-directed by the capacitor C8 to the controller.

The controller 250 includes a zener diode ZD3, an S1 U1, a first transistor Q1, and a second transistor Q2.

The zener diode (ZD3) is a detection signal of the detector 240, which is transmitted through the resistor (R9), that is, the AC power output from the noise removing unit 220 is converted into a DC through the detector 240 When the supplied power becomes an overvoltage of a predetermined voltage (for example, AC 380V) or more, the power is turned on and transferred to the SR U1.

The SR U1 is triggered when the zener diode ZD3 is turned on and the power is input through the gate terminal, and is transmitted to the first transistor Q1. SLC (U1) is a silicon control rectifier (SCR) and is a semiconductor device with high reliability and stable operation.

The capacitor C9 and the resistor R3 connected to the gate terminal of the SR U1 smooth and stabilize the power transmitted by the zener diode ZD3, and input the same to the SR U1. It protects the SRC (U1) and increases the accuracy of the trigger action.

When the SR U1 is triggered, the first transistor Q1 is turned on by applying the output power of the sensing unit 240 to the gate terminal.

The resistors R4, R5, and R6 connected to the gate terminal side of the first transistor Q1 protect the first transistor and increase the stability of on-off operation.

When the first transistor Q1 is turned on, the second transistor Q2 is turned on by applying the output power of the first transistor to the gate terminal.

The resistors R7 and R8 connected to the gate terminal side of the second transistor Q2 and the diode D6 connected between the drain terminal and the source terminal protect the second transistor Q2 and perform on / off operation. Increase stability

When the second transistor Q2 is turned on, the starting power of the starting power supply unit 260 is supplied to the driving coil RC of the switching unit through the second transistor Q2, and thus the switching unit 230. Magnet switch (RS) is turned off to block the over-voltage commercial AC power supply to the power supply (100).

The back EMF blocker 270 blocks back EMF from the power supply 100 through the driving coil RC of the switching unit 230.

The back EMF blocking unit 270 includes two zener diodes ZD1 and ZD2 connected in series with the diode D5 and the varistor MOV2 connected in parallel to the driving coil RC.

The starting power supply unit 260 rectifies and smoothes the output AC power of the noise removing unit 220 to supply the starting power to the switching unit 230.

The starting power supply 260 is a bridge diode (D1 ~ D4) for rectifying the output AC power of the surge blocking unit 220, and the capacitor (C5) for smoothing the rectified power from the bridge diode (D1 ~ D4) , C6, and resistors R1 and R2 for applying the starting power smoothed by the capacitors C5 and C6 to the switching unit 33.
