Description

Dimming-controlled LED lighting device {DIMMING-CONTROLLED LIGHT EMITTING DIODE FLUORESCENT APPARATUS}

The present invention relates to an LED lighting device, and more particularly to a dimming control LED lighting device.

Building on the trend of eco-friendly energy saving, buildings are also making efforts to reduce energy consumption. In particular, the efficient use of energy is very urgent due to a power outage caused by an overload of power.

In large buildings, a lot of power is consumed in elevators, escalators, lighting, etc. In particular, lighting consumes nearly 30% of the total power energy. Accordingly, energy is saved by increasing the installation of LEDs and controlling the on / off of lighting using a sensor. In particular, sensors are frequently used in places where people and cars are not frequent, such as parking lots, corridors, and stairs.

By the way, the existing sensor lighting is configured to be turned on only when a person or a car enters a certain radius from the sensor, and immediately turn off when a certain radius is out of the predetermined radius. As a result, the illumination is turned on only around the radius around which the person or the car moves, so that the vision of a farther distance is not properly secured. This is especially the case in large parking lots, long corridors, and stairs in tall buildings. As a result, psychological anxiety and embarrassment may occur. In addition, there is a problem that an accident may occur due to the lack of visibility, and the collision risk is greater during a relatively high speed vehicle movement.

On the other hand, conventionally, when the sensor is broken, the lighting itself is not operated, there is a problem that is very inconvenient and dangerous.

In order to solve the above problem, Patent Document 10-0970581 discloses a dimming control apparatus and method, which is

 1 is a block diagram of a dimming (dimming) control LED lighting device according to an embodiment of the present invention.

Referring to FIG. 1, the dimming control LED lighting device 100 (hereinafter, referred to as a “dimming control LED lighting device”) according to an embodiment of the present invention may include an AC power supply unit 110, an LED lighting device 120, and a dimming value. The setting unit 130, the off delay setting unit 140, the DC power supply unit 150, the microwave sensor 160, the dimming control unit 170, and the error control unit 180 may be configured to be included.

The dimming control LED lighting device 100 is configured such that the sensor-operated LED lighting 120 is dimmed between a minimum output value and a maximum output value instead of being rapidly turned on or off according to a sensing operation, thereby saving energy and at the same time psychological anxiety. Can solve the problem and prevent accidents. Further, even when the operation output contact state of the sensor is changed from the OFF state to the ON state, a minimum off delay time can be provided, thereby providing psychological stability. In addition, even if the microwave sensor 160 or the dimming control unit 170 fails, the error control unit 180 detects this in advance, so that the LED lamp 120 maintains the maximum output. Thus, accidental accidents can be prevented. Hereinafter, the detailed configuration will be described.

The AC power supply unit 110 is configured to supply AC power.

The LED lamp 120 is configured to emit light by receiving power from the AC power supply 110. LED light 120 is less power consumption than conventional incandescent or fluorescent light and can be called semi-permanent, it can be said to be useful for energy saving and environmentally friendly.

The dimming value setting unit 130 is configured so that the user sets the minimum output value and the maximum output value of the LED lamp 120 differently according to the installation zone. The dimming value setting unit 130 may set the minimum output value and the maximum output value differently according to the use such as a parking lot, a parking passage, a parking surface, a hallway, a staircase, and a kitchen. For example, in the general parking passage of the parking lot, the minimum output value is 4W, or the OFF state can be arbitrarily set by the user such as 18W maximum output value. A value between the minimum output value and the maximum output value set by the dimming value setting unit 130 is an output section for dimming control.

The off delay setting unit 140 may turn off the delay time for each installation area so that the OFF state can be further maintained when the operation output contact state of the sensor is changed from the OFF state to the ON state. DELAY TIME). The off delay time can be set, for example, from 1 second to 99 seconds depending on the installation zone, and also the off delay time can be longer depending on the location. The off delay time can be set to a shorter delay time because a place such as a stairwell or a kitchen is relatively low, but a longer delay time can be set in a place such as an underground parking lot which is rare. Can be.

The DC power supply unit 150 is a configuration for supplying DC power. The DC power supply 150 supplies DC power to all the devices except the lighting and the microwave sensor 160, which is to prevent the detection error due to the AC noise in the microwave sensor 160.

The microwave sensor 160 receives power from the DC power supply unit 150 and is attached to an independent configuration, or attached to the LED lamp 120 to sense the movement of a vehicle or a person. Unlike the conventional, by using the microwave sensor 160, it is possible to increase the sensing sensitivity. On the other hand, the microwave sensor 160 is configured to adjust the detection area angle, it can eliminate the blind area. In addition, the microwave sensor 160 may be configured as a separate configuration, or may be configured to be easily attached to an existing lighting device.

The dimming controller 170 sets the output of the LED lamp 120 to the minimum output value set by the dimming value setting unit 170 in a state where the lamp is normally turned off, and the microwave sensor 160 detects movement. In the OFF state, the output value of the LED lamp 120 is set to be changed to dimming to the maximum output value set by the dimming value setting unit 130, and the ON detected by the microwave sensor 160 disappears again. ) Is set to dimming the output value of the LED lamp 120 to the minimum output value after the off delay time set by the off delay setting unit 140. If the minimum output value is set to approximately 4W, all the space in the underground parking lot to maintain the minimum illuminance, thereby reducing power consumption and visibility. In addition, it is possible to prevent the sudden change in the illuminance by changing the output value dimming. Meanwhile, the dimming controller 170 may be configured to use an existing dimmer of the incandescent lamp as it is in the LED lamp 120.

When the microwave sensor 160 or the dimming control unit 180 is broken, the error control unit 180 is turned off instead of the minimum power consumption when the LED light 120 is in an off state. It is configured to automatically change the lamp to the maximum output value when in the ON state. Here, the error controller 180 is configured to receive a signal periodically from the microwave sensor 160 or the dimming controller 180, it may be configured to detect an operation error or failure.

Due to this, the dimming control LED lamp device 100 can save energy of about 78-85% compared to the conventional.

2 is a flowchart of a dimming control method of the LED lighting device according to an embodiment of the present invention.

Referring to FIG. 2, first, the dimming value setting unit 130 sets the minimum output value and the maximum output value of the LED lamp 120 differently according to the installation zone (S110).

In addition, the off delay setting unit 140 sets the OFF delay time differently for each installation zone so that the off state can be further maintained when the operation output contact state of the sensor is changed from the off state to the on state ( S120).

The error control unit 180 detects whether the microwave sensor 160 or the dimming control unit 170 is broken (S130). In this case, in the case of a failure, the error controller 180 is turned off instead of the minimum power consumption when the LED lamp 120 is in an OFF state, and maximum output of the lamp when the lamp is in an ON state. By setting to keep the value (BYPASS), the LED lamp 120 emits light at the maximum output (S150).

On the other hand, if not a malfunction, the microwave sensor 160 detects the movement of the vehicle or person (S140).

At this time, when the operation output contact state of the sensor in which the movement of the vehicle or the person is not detected is ON, the LED lamp 120 is set and output as the minimum output value of the corresponding installation area (S160).

On the other hand, when the operation output contact state of the sensor when the movement of the vehicle or the person is detected in the OFF (OFF) state, the LED lamp 120 is set to the maximum output value of the corresponding installation area is output (S170). In addition, the state in which the operation output contact state of the sensor is OFF is a state in which the microwave sensor 160 continuously detects the movement of a vehicle or a person (S180). At this time, the LED lamp 120 maintains the maximum output value during the off delay time in the ON state in which the movement of the vehicle or the person disappears again (S190).
