Description

[0001] The present invention relates to a parking light having a motion detection device,

The present invention relates to a park and the like provided with a motion detection device installed on a walkway of a park or the like, the angle of which can be accurately and effectively controlled depending on the presence or absence of a pedestrian.

In general, a light emitting diode (hereinafter referred to as LED) is a semiconductor device that emits light by flowing a current through a compound such as gallium arsenide, and injects a small number of carriers (electrons or holes) using a semiconductor pn junction structure. .

LEDs are needed to create flashing lights when the hard drive is spinning from the computer, large display boards on buildings in the city center, and invisible rays that send signals to the TV body each time the TV remote control button is pressed.

Since LEDs are highly efficient in converting electrical energy into light energy, LEDs can save up to 90% of energy and are attracting attention as a next-generation light source that can replace incandescent and fluorescent lamps with an energy efficiency of only 5%.

When an electric current passes through a conductive material with an electrode on the lower side, a positive charge particle called an electron and a hole are combined at the center of the electrode to emit a photon of light. The color differs depending on the characteristics of the material.

On the other hand, parks are installed on the walkways of the park for the safety of pedestrians, and these parks are also being replaced by LEDs.

In this connection, the present applicant has filed a patent application No. 10-2013-0152285 entitled "LED device having an external heat dissipating structure" and registered on Dec. 3, 2014 with the registration number 10-1470867.

The park may be configured to be turned on only at night through a timer or an ambient light sensor. However, even if there is no pedestrian due to the nature of the park, it is possible to shorten the life span of the park, There is a problem that the cost of lighting management is increased.

Accordingly, there has been already proposed a technique of controlling the lighting of the park by controlling the on / off of the park according to the presence or absence of the pedestrian by installing a motion sensor in the park so as to detect the motion of the person in the park. Motion detection sensors include optical sensors and ultrasonic sensors.

The optical sensor is a device that detects the object using light. The optical sensor detects the amount of light, the movement or the speed of the object, and the pulse-modulated light emitted from the light- The incident light to the element is increased or decreased, and when the rectified signal level of the incident light which has increased or decreased in this way reaches the operation level, it is common to output the output.

An ultrasonic sensor is a sensor that detects the position or distance of an object by using a high frequency sound of 20 kHz to 30 kHz which can not be heard by the human ear. When a voltage is applied to a diaphragm having a thickness of 2 to 3 μm, ultrasonic waves are generated, When the ultrasonic waves are detected again by the vibrator, the longer the distance to the object is, the longer the time from reflection to returning is, so that the distance to the object can be known.

However, when the optical sensor and the ultrasonic sensor are installed inside the lamp cover of a park, there is a problem that the lamp cover does not detect the external movement, so that it is protruded outside the lamp cover of the park, There is a possibility of occurrence.

Accordingly, a microwave sensor capable of detecting motion through a lamp cover even if installed in a lamp cover of a park or the like has been proposed. In this case, the antenna transmitter and the antenna receiver are formed in one module using the Doppler radar principle A high frequency wave is generated through a local signal generator and is applied to an object to be sensed so that the energy returned from the object can be sensed and captured through the sensor and the sensed energy of the emitted energy and the transmitted wavelength light are mixed, Is configured to calculate the low-frequency voltage, and finally, the operation of the sensor is performed by communication between an external control unit electrically connected to the control unit and software installed in the control unit.

However, since the motion sensing sensors such as the optical sensor, the ultrasonic sensor, and the microwave sensor described above determine the angle and direction of sensing, there is a problem in that it is difficult to match the sensing direction when the position of the motion sensing sensor is restricted.

In addition, when a motion detection sensor is installed in a park installed along a walkway of a park, a motion detection sensor installed in a park or the like accurately detects the movement of a pedestrian moving along the walkway in accordance with the correlation between the already- If the motion detection sensor is not adjusted according to the changed movement line, if the motion line of the pedestrian using the walkway is changed according to the situation even if the detection range of the motion detection sensor is adjusted to the walkway, And there is a problem that the crime prevention function of the park or the like is lost.
