Description

Position-controlled illuminance measuring device and method {POSITION-CONTROLLED ILLUMINANCE MEASURING DEVICE AND METHOD}

The present invention relates to a device and method for measuring illuminance, and more particularly, to a device for measuring illuminance by adjusting the positions of a plurality of illuminance measurement sensors, the device comprising: a distance adjustment unit for moving the illuminance measurement sensors respectively in a plane direction to adjust the distance in the plane direction; a height adjustment unit for supporting the distance adjustment unit from below and raising and lowering the distance adjustment unit to adjust the height of the illuminance measurement sensor; and a control unit for controlling the distance adjustment unit and the height adjustment unit, the illuminance measurement device and method being capable of adjusting the illuminance measurement height and position in accordance with the KS standard, thereby enabling more convenient illuminance measurement.

Generally, illuminance refers to the intensity of light, and in order to measure this illuminance, the KS standard for lighting measurement (KS C 7612) is followed. This KS standard stipulates the height of the illuminance measurement surface and the measurement point. For example, in the case of a living room, it is stipulated as 40±5cm above the floor, and in the case of a hallway or outdoors, it is stipulated as 15cm above the floor or ground. In addition, regarding the illuminance measurement point, considering the light distribution and attachment height of the lighting fixture, in the case of a direction or location where the illuminance change is large, the illuminance measurement interval is set small, and conversely, in the case of a direction or location where the illuminance change is small, the illuminance measurement interval is set large.

In other words, the height and spacing of the illuminance measuring sensor must be adjusted depending on the illuminance measurement location or lighting conditions.

However, in the case of conventional technologies, a technology for measuring illuminance while moving the illuminance measurement point has been proposed, but a technology for simultaneously adjusting the height and measurement point for measuring illuminance has not been proposed, so there has been a problem in that it is difficult to measure illuminance according to the KS standard.

Meanwhile, the above-described illuminance measuring device itself is widely known and is described in detail in the prior art literature below, so its description and illustration are omitted.

Therefore, the definitions of these terms should be made based on the contents throughout this specification.

In addition, the examples below do not limit the scope of the present invention, but are merely exemplary of the components presented in the claims of the present invention. Examples that include components that are included in the technical idea of the entire specification of the present invention and can be substituted as equivalents in the components of the claims may be included in the scope of the present invention.

A measuring device (10) according to one embodiment of the present invention is a device for measuring illuminance by adjusting the positions of a plurality of illuminance measuring sensors (S), as illustrated in FIGS. 1 to 8, wherein the device includes a distance adjusting unit (200) for adjusting a distance in a plane direction by moving the illuminance measuring sensors (S) respectively in a plane direction, and a height adjusting unit (100) for supporting the distance adjusting unit (200) from below and raising and lowering the distance adjusting unit (200) to adjust the height of the illuminance measuring sensors (S). That is, the height of the illuminance measuring sensors (S) can be adjusted by the height adjusting unit (100), and the distance in the plane direction of the illuminance measuring sensors (S) can be adjusted by the distance adjusting unit (200), so that the illuminance measurement position can be adjusted in accordance with the KS standard, thereby allowing for more convenient and accurate measurement of illuminance.

Meanwhile, the illuminance measurement sensor (S) can be equipped in a sensor holder (250) described later, and the illuminance measurement sensor (S) itself can use an existing measurement sensor, so detailed description and illustration thereof are omitted.

The above distance adjustment unit (200) and height adjustment unit (100) can be adjusted manually or automatically. The above distance adjustment unit (200) and height adjustment unit (100) can be automatically adjusted by the control unit (CON). As described above, in order to measure the illuminance, the measurement height and the distance in the plane direction must be adjusted, and for this purpose, the height adjustment unit (100) and the distance adjustment unit (200) are included. At this time, the height adjustment unit (100) and the distance adjustment unit (200) can be controlled by the control unit (CON), and this control unit (CON) can use a PC, etc.

The height adjustment unit (100) includes a housing (150) that supports the distance adjustment unit (200) from the lower side. This housing (150) has a hollow shape with an open upper part. A power generation unit (110) is arranged inside the housing (150) to generate rotational force. This power generation unit (110) can use a widely known DC motor and can be controlled by a control unit. A feed screw (120) is arranged in the height direction on the power generation unit (110) and is rotated by the power generation unit (110). A lifting block (130) is provided on the feeding screw (120). This lifting block (130) is screw-connected with the feeding screw (120) and is raised and lowered by the rotation of the feeding screw (120). A base (170) is provided on the lifting block (130). This base (170) is raised and lowered in conjunction with the raising and lowering block (130), and the distance adjusting unit (200) described below is supported on the base (170). With this configuration, the distance adjusting unit (200) equipped with the illuminance measuring sensor (S) is raised and lowered by the raising and lowering of the base (170), thereby adjusting the height of the illuminance measuring sensor (S).

The above-mentioned raising/lowering block (130) is screw-connected with the feed screw (120) and rises/falls in accordance with the rotational direction of the feed screw (120). To this end, the above-mentioned raising/lowering block (130) includes a raising/lowering block body (131) whose inner surface is screw-connected with the feed screw (120) and rises/falls, and a linkage bar (132) that protrudes radially from the above-mentioned raising/lowering block body (131).

The housing (150) includes a housing body (151) that is hollow and has an open top, a guide slit (152) formed in the height direction on the housing body (151) through which the linkage bar (132) passes, and a scale (153) formed on one side of the housing body (151) to indicate the height of the linkage bar (132). That is, since the linkage bar (132) is inserted into the guide slit (152), the elevating block body (131) cannot rotate. Accordingly, the elevating block body (131) moves up and down according to the rotation of the feed screw (120). At this time, since the linkage bar (132) moves up and down along the guide slit (152), the elevating and down movement of the elevating block body (131) is guided. In addition, since a scale (153) is formed on the linkage bar (132), the height of the linkage bar (132) can be easily checked.

The above distance adjusting unit (200) includes a hollow case (270) that is fixed to the side of the base (170) and is provided in a plurality of circumferential directions. A power generating unit (210) is provided inside the case (270) to generate rotational force. The power generating unit (210) can use a widely known DC motor and can be controlled by a control unit to automatically adjust the distance. A feed screw (220) is provided inside the case (270) and is linked by the power generating unit (210). A moving block (230) is provided on the feed screw (220). The moving block (230) is screw-connected with the feed screw (220) so that the moving block (230) moves back and forth according to the rotational direction of the feed screw (220). An extension unit (240) extends outward from the moving block (230). The above extension (240) may have a bar shape as illustrated and moves back and forth in conjunction with the moving block (230). A sensor holder (250) is provided at the end of the extension (240). The sensor holder (250) is placed outside the case (270), and a light measurement sensor (S) is provided in the sensor holder (250). In other words, the moving block (230) and the extension (240) move back and forth by the rotation of the transfer screw (220), thereby adjusting the plane direction distance of the sensor holder (250), and thereby adjusting the plane direction distance of the light measurement sensor (S).

The above case (270) has a case body (271) that is hollow and has an open side opposite to the base (170), that is, an outer side. An opening (272) is formed on one side (the upper side in the illustrated embodiment) of the case body (271). The opening (272) is arranged in the longitudinal direction of the case body (271) and has a shape that is open to a specific width. A scale (273) is formed around the opening (272).

Inside the case body (271), a moving block (230) moves back and forth. To this end, the moving block (230) includes a moving block body (231) whose inner surface is screw-connected with the transfer screw (220). That is, the moving block body (231) moves back and forth according to the rotational direction of the transfer screw (220). An insertion part (232) protrudes from one side of the moving block body (231). The insertion part (232) is exposed to the outside through the opening part (272). Since the insertion part (232) is exposed and caught through the opening part (272), the moving block body (231) in which the insertion part (232) is formed moves back and forth without rotating by the rotation of the transfer screw (220). In addition, since the insertion part (232) corresponds to the scale part (273), the position of the insertion part (232) can be easily confirmed, and accordingly, the distance in the plane direction of the illuminance measurement sensor can be easily confirmed.

This distance adjusting unit (200) is provided on a base (170). The base (170) includes a plate-shaped base body (171) having a case (270) of the distance adjusting unit (200) provided on one side thereof, and a post (172) protruding from the lower surface of the base body (171). This base (170) is placed on a raising/lowering block (130), and an insertion groove (131-1) is formed on the upper surface of the raising/lowering block body (131) of the raising/lowering block (130), into which the post (172) is rotatably inserted. By this configuration, the distance adjusting unit (200) rotates in a plane direction. At this time, the distance adjusting unit (200) can be rotated manually or automatically. To this end, a rotation angle adjustment unit (300) may be included that is positioned in the insertion groove (131-1) of the elevating block (130) and rotates the base (170) to adjust the rotation angle of the distance adjustment unit (200) on a plane. The rotation angle adjustment unit (300) for this purpose may include a rotational force generation unit (330) that is positioned in the insertion groove (131-1) and generates rotational force, and a driving gear (340) that is linked by the rotational force generation unit (330) and rotates the post (172). The rotational force generation unit (330) may use a widely known DC motor, etc., and may be automatically adjusted by being controlled by the control unit. Meanwhile, a tooth shape may be formed on the outer surface of the post (172) that is rotated by the driving gear (340). By this configuration, the post (172) is coupled with the driving gear (340), so that the post (172) rotates, thereby allowing the base body (171) to rotate. By the rotation of the base body (171), the distance adjusting part (200) provided in the base body (171) can be rotated in a plane direction. Meanwhile, the rotation angle can be easily determined by the scale part (173) formed on the upper surface of the post (172) and indicating the rotation angle.

Meanwhile, the base (170) is provided on the body of the lifting/lowering block (131), and it is also possible to place a thrust bearing (BRG) on the body of the lifting/lowering block (131) so that the base (170) can rotate stably.

In addition, as shown in Fig. 1, the measuring device (10) of the present invention may include a wheel part (500) provided on the bottom surface of the height adjustment part (100) to enable movement of the height adjustment part (100). With this configuration, the measuring device (10) of the present invention can be conveniently moved to a required location, thereby enabling more convenient measurement of illuminance.

Hereinafter, referring again to FIGS. 1 to 8, a method for measuring illuminance using the illuminance measuring device (10) of the present invention will be described. That is, the height adjustment unit (100) and the distance adjustment unit (200) are adjusted manually or automatically.

In other words, it is possible to manually adjust the height of the illuminance measurement sensor (S), and it is also possible to automatically adjust the height of the illuminance measurement sensor (S) by controlling the height adjustment unit (100) by the control unit (CON). That is, when it is desired to adjust the height of the illuminance measurement sensor (S) according to the KS regulation, the power generation unit (110) of the height adjustment unit (100) is driven by the control unit (CON) to drive the feed screw (120), thereby raising and lowering the elevation block (130), thereby adjusting the height of the illuminance measurement sensor (S). For example, the height may be set to a total of 800 mm, with the first stage at a height of 400 mm, the second stage at a height of 600 mm, and the final third stage at a height of 800 mm. Meanwhile, the height may be determined by the point at which the interlocking bar (132) protruding from the elevation block (130) corresponds to the scale (153).

In addition, the distance adjustment unit (200) is controlled by the control unit (CON) to control the distance in the plane direction of the illuminance measurement sensor (S) to measure illuminance. For example, the starting point of the moving block (230) of the distance adjustment unit (200) is set to 1000 mm from the center point of the base (170), the maximum forward length is set to 1200 mm, and the control unit (CON) controls the power generation unit (210) to move the moving block (230) forward and backward within the above range, thereby adjusting the positions of the sensor holder (250) and the illuminance measurement sensor (S).

With this configuration, it is also possible to analyze the information collected by the illuminance measurement sensor (S) by transmitting it to an external information processing device (COM) via the control unit (CON) via wired or wireless transmission.

Although the present invention has been described in detail through specific examples, this is intended to specifically explain the present invention, and the present invention is not limited thereto, and it is clear that modifications and improvements can be made by those skilled in the art within the technical spirit of the present invention.

All simple modifications or changes of the present invention fall within the scope of the present invention, and the specific protection scope of the present invention will be made clear by the appended claims.
