Description

{Extended sensing lighting device}

The present invention relates to an extended sensor illuminating device, and more particularly, to an extended sensor illuminating device which is integrally provided in an extended sensor illuminating device and adjusts a sensing direction of a sensor capable of sensing a moving object, So that the detection blind spot can be solved.

Lighting in a space in which a lighting device is installed (for example, a tunnel, an underground parking lot, etc.), even when the lighting is unnecessary, causes a serious energy wastage. Accordingly, techniques for turning on illumination required only when a moving object (e.g., a car, a person, etc.) is sensed while the illumination is normally turned off or the brightness of the illumination is dark is widely known. In such an illumination device, there is a sensor for sensing a moving object. In general sensors capable of sensing a moving object, there may be a sensing blind spot in which a sensing angle and a sensing distance are limited and a moving object may not be detected.

1 shows a sensing range for sensing a moving object in a conventional lighting device.

Referring to FIG. 1, a conventional lighting apparatus 10 may include a sensor 20 for sensing a moving object. The sensing direction 1 of the sensor 20 may include a sensor (V) toward the bottom surface of the space in which the airbag is installed.

Each of the sensors 20 is provided at a central portion of the illumination device 10 and has a detection distance of several meters from the center of the illumination device 10. [

At this time, the sensor 20 detects the height h of the space, that is, the height h from the bottom surface to the illuminator 10 and the sensing angle a of the sensor 20, A sensing range A that can be sensed can be determined, so that the sensing distance l of the sensor 20 on the bottom surface can be determined.

For example, assuming that the space in which the illumination device 10 is installed is a parking lot, the height standard for installing the extended sensor illumination device 10 in the parking lot is generally defined as 2.1 m or more, The lighting device 10 is installed at a height of 2.1 m.

The sensing angle a of a general sensor is about 120 degrees although there is a difference depending on the type of the sensor 20. [ In this case, the sensing distance l of the sensor 20 (i.e., the distance the sensor 20 can detect on the bottom surface) may be about 7 m.

That is, conventionally, no illumination is output from the illuminator 10 unless the moving object reaches a radius of about 3.5 m from the center of the illuminator 10.

However, in general, a lighting apparatus installed in a space in which a car moves, such as a parking lot, is often installed at intervals of about 6 m to 7 m, thereby causing a blind spot in which the moving object is not detected between the illuminating devices . In this case, if the lighting output time of the lighting device sensing the moving object is not sufficiently set, the light passing through the moving object is turned off before the moving object passes through any one lighting device and outputs light to the next lighting device There is a risk to be able to.

Also, as the sensing distance of the sensor 20 is shortened, the light can be outputted from the lighting device 10 only if the moving object is close to the lighting device 10. If the vehicle is driven in an underground parking lot or a tunnel There is a problem that it becomes more difficult to secure a view even for a short time when the light is suddenly outputted in a dark space.

Further, in order to solve such a problem, if the installation interval of the illumination device 10 is narrowed, many lights may be turned on unnecessarily, waste of energy resources may occur, and a special sensor having a wide sensing angle a may be used There is a problem that the cost is increased.

Accordingly, it is an object of the present invention to provide an illumination device capable of substantially eliminating the blind spot of the sensor by making it possible to extend the detection distance of the sensor while using an ordinary sensor capable of sensing a moving object as it is, Is urgently required.

Therefore, a technical problem to be solved by the present invention is to provide an illumination device which can effectively control the installation position and / or sensing direction of a sensor that can detect a moving object integrally provided in a lighting device, So as to provide a technical idea capable of eliminating the blind spot.

It is another object of the present invention to provide a technical idea that includes a plurality of sensors in the illumination device and significantly extends the sensing distance by adjusting the sensing direction of each of the plurality of sensors, thereby completely eliminating the blind spot.

According to an aspect of the present invention, there is provided an extended sensor illumination apparatus including a sensor unit including a plurality of sensors capable of sensing a moving object, And a first sensor of the plurality of sensors detects a sensing direction of the first sensor in a space in which the extended sensor illuminating device and the extended sensor illuminating device are installed And a second sensor of the plurality of sensors is formed to detect the sensing of the second sensor in order to extend the sensing distance, And fixed so as to have a slope with respect to the vertical direction by a predetermined angle in a second direction opposite to the first direction It can be characterized.

The first sensor may be fixed to one side of the extended sensor illumination device, and the second sensor may be fixed to the other side of the extended sensor illumination device, and the one side and the other side may be And each of the first and second electrodes is inclined to have a slope by a predetermined angle with respect to the vertical direction.

The predetermined angle may be in the range of 20 degrees to 30 degrees.

According to the technical idea of the present invention, by adjusting the installation position and / or the sensing direction of a sensor that can detect a moving object integrally provided in a lighting device, it is possible to substantially extend the sensing distance even when the same sensor is used There is an effect that the detected blind spot can be solved.

Further, the illumination device has a plurality of sensors, and the detection distance can be remarkably extended by adjusting the sensing directions of the plurality of sensors, and the detected blind spot can be substantially completely eliminated.

Hereinafter, the present invention will be described in detail with reference to the embodiments of the present invention with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

2 shows a schematic configuration of an extended sensor illumination device according to an embodiment of the present invention.

Referring to FIG. 2, the extended sensor illumination apparatus 100 according to the embodiment of the present invention includes a sensor unit 110 and an illumination unit 120. Although it is not shown in the drawing, the extended sensor illumination device 100 may further include predetermined components (for example, a power supply unit, a memory, and the like) necessary for realizing the technical idea of the present invention. Can be easily deduced to the average expert of.

The extended sensor illumination device 100 may be installed in various spaces such as a hallway, a tunnel, an underground parking lot, etc. in which illumination is required. In addition, the extended sensor illumination device 100 may perform dimming according to preset conditions that are normally set in advance. For example, when the predetermined moving object, such as a person or a vehicle, is not detected for a predetermined period of time, or when the brightness of the outside is greater than or equal to a predetermined brightness and / or a predetermined time period (e.g., 8:00 am to 5:00 pm) It can also mean a condition of a situation in which it is not necessary to always output illumination.

In the present specification, the extended sensor illumination device 100 performs the dimming by maintaining the brightness of the illumination output from the extended sensor illumination device 100 at a constant level or below, Quot; state ".

The illumination unit 120 may selectively output illumination depending on whether the moving object is detected by the sensor unit 110. [

For example, when a predetermined mobile object (e.g., a person, an automobile, etc.) is detected by the sensor unit 110, the extended sensor illumination device 100 outputs illumination through the illumination unit 120, So that the moving object can be easily secured to the field of view.

For this, the extended sensor illumination device 100 may include the sensor unit 110. The sensor unit 110 may include a predetermined sensor capable of sensing a moving object. Since the sensors capable of sensing a moving object within a predetermined sensing range are well known, a detailed description thereof will be omitted herein. If a moving object can be detected, the sensor included in the sensor unit 110 can be any type Do.

As described above with reference to FIG. 1, the sensor capable of sensing a moving object may have a specific sensing range according to the sensing angle 'a'. In general, such a sensor may have a sensing angle 'a' . In addition, the sensing direction of the sensor included in the conventional extended sensor illuminating device is realized to be perpendicular to the bottom surface of the space where the extended sensor illuminating device is installed.

In addition, considering the fact that the lighting height is set at 2.1 m or more in a general parking lot, and most of the parking lots are installed at a height of 2.1 m, the detection distance l) may be about 7 m. In addition, most of the conventional extended sensor illuminating apparatuses are equipped with a single sensor to detect a moving object, so that the sensor detects the moving object installed in the center of the conventional extended sensor illuminating apparatus in the same range in any direction To be implemented. In this case, the moving object can be detected by the sensor only when it is within a radius of 3.5 m of the conventional extended sensor illumination device.

Therefore, the conventional extended sensor illuminating device can be installed within an interval of 3.5 m or less to detect a moving object without a blind spot in the detection range of the sensor, and the interval between the extended sensor illuminating devices can be set to 3.5 m There is a risk that the dimming control of the extended sensor illumination device may be problematic because the area in which the moving object is not detected increases. However, in general, the installation interval of the illumination installed in the space where a car passes such as a parking lot is about 6m to 7m, and a space where a moving object (e.g., an automobile) can not be detected by the sensor There is a problem that can not be solved.

However, according to the technical idea of the present invention, the conventional sensing distance can be significantly increased while using a general sensor having a sensing angle (a) of about 120 degrees, so that the blind spot of sensing by the sensor can be easily eliminated . Hereinafter, the technical idea of the present invention will be described in detail with reference to FIG. 3 to FIG.

FIG. 3 shows an example of the sensing range according to the inclination of the sensing direction of the sensor in the extended sensor illuminating device according to the embodiment of the present invention, FIG. 4 shows an example of a sensor formed in the extended sensor illuminating device according to the embodiment of the present invention For example.

Referring to FIG. 3, first, a virtual vertical direction (V) connecting vertically the bottom surface of the space where the extended sensor illumination device 100 is installed and the center of the extended sensor illumination device 100 may be assumed. The sensor included in the sensor unit 110 may be formed at one side of the extended sensor illumination device 100, not at the center of the extended sensor illumination device 100, as shown in FIG. When the sensor is formed on one side of the extended sensor illumination device 100, the moving object approaching in the direction of the one side can be detected relatively quickly, that is, the sensing range can be substantially enlarged. The sensing direction of the sensor formed on one side of the extended sensor illumination device 100 is parallel to the vertical direction V (i.e., the sensing direction is not perpendicular to the bottom surface) V, the portion where the sensor is formed may be inclined at an angle as shown in the figure so that the sensor can be inclined at a predetermined angle. Of course, the portion where the sensor is formed may be formed so that the sensor itself has a certain slope even if it is not apparently tilted.

Although the extended sensor illumination device 100 is shown in the form of a fluorescent lamp as an example, the extended sensor illumination device 100 may be implemented in various forms such as a circle or a rectangle and various types of illumination Of course. Regardless of the type or type of the extended sensor illumination device 100, the sensor can be formed at one side of the extended sensor illumination device 100 to implement the technical idea of the present invention.

In this specification, one side of the extended sensor illumination device 100 may include a case where the side of the extended sensor illumination device 100 is offset from the center of the extended sensor illumination device 100 in any one of the lateral directions. For example, the one side portion may mean a side end (a side end) of the extended sensor illumination device 100, but may be located inside the extended sensor illumination device 100 at a certain distance in the direction toward the center of the extended sensor illumination device 100 May be included. Of course, depending on the embodiment, the sensor may be formed at a central portion of the extended sensor illumination device 100, and in this case also, the sensing direction of the sensor may be set at a predetermined angle As shown in FIG. In addition, the other side of the extended sensor illumination device 100 may refer to a side of the extended sensor illumination device 100 on the opposite side of the side of the central portion.

Referring to FIG. 3, the sensing direction of the sensor is a first direction (1), a second direction (2), and a third direction (3). In this specification, the sensing direction of the sensor may refer to a virtual line connecting the center of the sensing range in which the sensor can sense the moving object, as shown in the figure. For example, as shown in Fig. 1, a virtual straight line 1 starting from the central portion (i.e., the sensor 20) of the sensing range A of the sensor 20 may be the sensing direction of the sensor 20 have.

1, the sensing direction of the sensor is parallel to the bottom surface in the vertical direction, that is, parallel to the vertical direction (V), as in the conventional extended sensor illumination device described above with reference to FIG. Direction. In this case, the sensor has a sensing range A, and the sensing distance may be ll.

The second direction 2 may have a slope of about 10 to 20 degrees in one direction with respect to the vertical direction V. In this case, the sensor has a sensing range B, lt; 2 >.

Assuming that the sensing angle a of the sensor is 120 degrees and the height of the space in which the extended sensor illumination device 100 is installed is 2.1 meters, the sensing of the sensor along the first direction (1) The distance, i, may be about 7 m. In this case, as described above, when the moving object approaches from the direction of the one side where the sensor is installed, the moving object can be detected by the sensor only when it reaches the distance of about 4 m to 5 m from the extended sensor illumination device 100.

When the sensing direction of the sensor is the second direction (2) having a slope of about 10 to 20 degrees with respect to the vertical line (V), the detection distance of the sensor along the second direction (2) That is,? 2 may be about 8 m to 9 m. Therefore, in this case, the sensor can detect the moving object when the moving object reaches the distance of about 6 m to 7 m from the extended sensor illumination device 100, and as described above, It is possible to eliminate most of the blind spot of the sensing range of the sensor.

In addition, when the sensing direction of the sensor has a slope of about 30 degrees or more in one direction with respect to the third direction (3), that is, the vertical direction (V) The sensing distance according to the range C can be extended to the maximum sensing distance that the sensor can sense. In general, the sensing distance of a sensor capable of detecting the movement of a moving object may vary from about 5 m to about 25 m for each sensor type. For example, when a specific sensor having a sensing distance of 10 m is used, the detection distance of the specific sensor is limited to about 7 m regardless of the sensing distance of the specific sensor when the sensing direction of the specific sensor is the first direction (1) If the sensing direction of the specific sensor is the third direction (3), the sensing distance may be extended to about 10 m, which is the sensing distance of the specific sensor.

As a result, according to the technical idea of the present invention, a sensor is formed on one side of the extended sensor illumination device 100, and the sensing direction of the sensor is perpendicular to the bottom surface of the space in which the extended sensor illumination device 100 is installed (For example, 20 degrees or 30 degrees) without using the same sensor, it is possible to substantially extend the sensing distance of the sensor while using the same sensor.

When the sensor is formed on one side of the extended sensor illumination device 100 as described above, the direction of the other side of the extended sensor illumination device 100, that is, the center direction of the extended sensor illumination device 100 There is a problem that the moving object can not be detected when the moving object approaches the other side direction than the one side direction. Therefore, according to the technical idea of the present invention, the sensor unit 110 includes a plurality of sensors so that the extended sensor illumination device 100 can completely eliminate the blind spot of the detection range in which the moving object can be detected . Such an example will be described with reference to Fig.

FIG. 5 shows an example in which a plurality of sensors are provided in the extended sensor illumination device according to the embodiment of the present invention.

Referring to FIG. 5, the sensor unit 110 may include a plurality of sensors. Hereinafter, for the sake of convenience of explanation, the sensor unit 110 includes two sensors, for example, a first sensor 120-1 and a second sensor 120-2. And the number of sensors included in the sensor unit 110 may be added as much as necessary.

5, the first sensor 120-1 is formed on one side of the extended sensor illumination device 100 according to the embodiment of the present invention, and the other side of the extended sensor illumination device 100 The second sensor 120-2 may be formed.

At this time, the sensing directions of the first sensor 120-1 and the second sensor 120-2 are respectively determined as a space in which the extended sensor illumination device 100 and the extended sensor illumination device 100 are installed (V) that connects the bottom surfaces of the first and second guide grooves. For example, when the sensing direction of the first sensor 120-1 is a first direction, the sensing direction of the second sensor 120-2 may be a second direction opposite to the first direction. When the first direction and the second direction are opposite to each other, the first direction and the second direction are not simply opposite to each other on the same line, but the first direction and the second direction are And may be symmetrical with respect to the vertical direction (V).

For example, the first sensing direction of the first sensor 120-1 may have a slope of about 20 degrees with respect to the vertical direction V toward one side of the extended sensor illumination device 100. [ The second sensing direction of the second sensor 120-2 may have a tilt of about 20 degrees with respect to the vertical direction V toward the other side of the extended sensor illumination device 100. [ Then, as shown in the figure, the blind spot where the moving object is not sensed can be substantially completely canceled by the detection range of each of the first sensor 120-1 and the second sensor 120-2.

The sensing distance at which the extended sensor illumination device 100 can sense the moving object is determined by the sensing distance l of the first sensor 120-1 and the sensing distance l ' L may be combined more than a certain amount.

3, when the detection distance of each of the first sensor 120-1 and the second sensor 120-2 is about 8 m, the extended sensor illumination device 100 detects the moving object The sensing distance can be extended to about 12 m except for a part of the central portion of the extended sensor illumination device 100 in which the sensing range of the first sensor 120-1 and the second sensor 120-2 overlap, .

If the first sensing direction of the first sensor 120-1 has a slope of 30 degrees in one direction of the extended sensor illumination device 100 with respect to the vertical direction V and the second sensor 120- 2 is inclined by 30 degrees in the other direction of the extended sensor illumination device 100 with respect to the vertical direction V, the first sensor 120-1, as described above, And the maximum value of the sensing distance of each of the second sensors 120-2 may be the detection range of the extended sensor illumination device 100. [

As a result, according to the technical idea of the present invention, in order to solve a detection blind spot in which a moving object can not be detected in a conventional extended sensor illuminating device, the installation position of the sensor included in the extended sensor illuminating device It is possible to have a remarkably convenient effect of completely eliminating the blind spot of the sensor by using the direction and the direction.

On the other hand, the detection range of the first sensor 120-1 and the second sensor 120-2 is partially overlapped with the central portion of the extended sensor illumination device 100, but the present invention is not limited thereto. For example, according to an embodiment, the first sensor 120-1 and the second sensor 120-2 may be controlled so that the sensing range of the first sensor 120-1 and the sensing range of the second sensor 120-2 do not overlap with each other, The sensor 120-2 may be formed in the extended sensor illumination device 100, respectively, and this can be changed as much as the user needs.

It will be understood by those of ordinary skill in the art that the foregoing description of the present invention has been presented for purposes of illustration and that those skilled in the art will readily understand that various changes in form and details may be made therein without departing from the spirit and scope of the invention. will be.

It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.

The scope of the present invention is defined by the appended claims rather than the foregoing description, and all changes or modifications derived from the meaning and scope of the claims and equivalents thereof are to be construed as being included within the scope of the present invention .
