Description

[Technical Field]

[0001] The present invention relates to a camera device that is attached to a straight tube type LED light. [Background technology]

[0002] An example of a camera device used with a straight-tube LED light is shown in Patent Document 1. This camera device is a light-integrated camera device that is pre-assembled integrally with the end of a straight-tube LED light, and its main purpose is to provide an LED light that can be easily replaced with existing incandescent lamps or fluorescent lamps, and to provide an illumination lamp that also functions as a surveillance camera simply by replacing the existing lamp. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-200922 Summary of the Invention [Problem to be solved by the invention]

[0004] However, although it is true that such LED lights with integrated camera devices can be used to provide lighting lamps that also function as surveillance cameras by replacing existing incandescent lamps or fluorescent lamps, there are the following problems.

[0005] (1) Normally, the lifespan and service life of the LED light and the camera device are different. Therefore, if the function of one of them is impaired, the other, which does not yet need to be replaced, will also have to be replaced at the same time, which is uneconomical and increases operating costs.

[0006] (2) Because the LED light and the camera device are assembled as a single unit, the mounting angle of the camera device relative to the LED light is kept constant. Furthermore, the mounting angle (around the axis) of the LED light relative to the lighting fixture is determined in advance by the orientation of the LED light's terminals (i.e., the orientation of the two terminals extending parallel to each other at a predetermined distance). Therefore, when an LED light equipped with an LED light is attached to a lighting fixture, the imaging range (imaging direction) of the camera device is fixed, making it difficult to capture images in any direction, resulting in a lack of versatility and convenience.

[0007] SUMMARY OF THE INVENTION The present invention has been made with the objective of proposing a camera device that is economical in terms of installation and operation costs, and is also versatile and convenient. [Means for solving the problem]

[0008] The present invention employs the following configuration as a specific means for solving the above problems.

[0009] In the first invention of the present application, there is provided a camera device that is attached to a straight tube type LED light that is attached between the left and right sockets of a lighting fixture, and that includes a case that is provided with a light insertion hole through which the LED light can be inserted in the axial direction and a unit storage section in which an imaging unit equipped with an imaging lens is stored and arranged, and that is attached to the end of the LED light with the LED light inserted into the light insertion hole. It is configured as follows: Furthermore, a closing plate is provided at one end of the light insertion hole of the case so as to close the light insertion hole, and the closing plate is provided with a power feed blade having a terminal insertion hole that is in conductive contact with the outer surface of the terminal of the LED light, and a power feed cable that feeds power to the imaging unit is connected to the power feed blade, so that when the terminal of the LED light is connected to the socket of the lighting fixture through the terminal insertion hole of the power feed blade, power is fed from the terminal to the imaging unit via the power feed blade. It is characterized by the following.

[0011] The first part of this application 2 In the present invention, 1 In the camera device according to the invention, the closing plate is attached to one end of the light insertion hole of the case so as to be rotatable about its axis. [Effects of the Invention]

[0012] The present invention provides the following effects.

[0013] (a) First Invention of the Present Application (1) The camera device according to the first aspect of the present invention is provided with a case having a light insertion hole through which the straight tube LED light can be inserted in the axial direction and a unit storage section in which an imaging unit equipped with an imaging lens is stored and arranged, and the camera device is attached to the end of the LED light with the LED light inserted into the light insertion hole. Therefore, the camera device can be attached to an existing LED light that is not scheduled to be replaced or a new LED light that is to be replaced, and can be used after the fact, thereby providing a camera device that is highly economical and versatile.

[0014] (2) Furthermore, unlike the camera device integrated with an LED light shown in Patent Document 1, for example, there is no need to replace the LED light and camera device as a whole. Instead, it is possible to selectively replace only the LED light or only the camera device, which is economical and ultimately reduces the operating costs of the camera device.

[0015] (3) Furthermore, in this invention, a closing plate is provided at one end of the light insertion hole of the case so as to close the light insertion hole, and the closing plate is equipped with a power feed blade having a terminal insertion hole that is in conductive contact with the outer surface of the terminal of the LED light, and a power feed cable that supplies power to the imaging unit is connected to the power feed blade, so that when the terminal of the LED light is connected to the socket of the lighting fixture through the terminal insertion hole of the power feed blade, power is supplied from the terminal via the power feed blade to the imaging unit. Therefore, when installing the camera device, there is no need to provide a dedicated power feed means for the imaging unit of the camera device, which reduces the installation costs of the camera device and allows for greater flexibility in installation work, enabling installation costs to be reduced.

[0016] ( b ) The first of this application 2 invention of The first part of this application 2 In the camera device according to the present invention,a ) in addition to the effects described above, the following unique effect can be obtained. That is, in this invention, the closing plate is attached to one end of the light insertion hole of the case so as to be rotatable about its axis. Therefore, although the circumferential attachment position of the LED light relative to the lighting fixture is determined by the position of the terminal of the LED light, the relative position of the camera device relative to the LED light is allowed by the rotatability of the closing plate, and therefore the orientation direction of the imaging lens of the camera device (imaging position) can be changed. As a result, the camera device is highly versatile, and when used for security purposes in particular, the camera device has significant effects, such as being able to accurately capture images of desired locations.

[0018] 1 and 2 show a state in which a camera device 1 according to an embodiment of the present invention is attached to an end of an LED light 3 attached to a lighting fixture 2 installed on a ceiling surface W.

[0019] A: 3 LED lights The LED light 3 has a light body 3a of a predetermined length, and a base 3b with a terminal 3c at each end. The LED light 3 is attached between a power-feeding socket 2a and a non-power-feeding socket 2b, which are provided at both left and right ends of a lighting fixture 2 attached to a ceiling surface W. The camera device 1 is attached to the end of the LED light 3 closer to the power-feeding socket 2a.

[0020] B: Camera device 1 3 to 8, the camera device 1 includes a case 11. The case 11 has a substantially triangular prism-like appearance and functions as a member for fixing and holding the imaging unit 14 and as a member for attaching the case 11 to the LED light 3. In this embodiment, the case 11 has a divided structure made up of multiple parts (the division positions are set appropriately as needed) in consideration of the ease of assembling the components of the imaging unit 14 (the imaging section 15, recording section 16, and control section 17, which will be described later) and the ease of maintenance work.

[0021] B-1: Function as a fixing and holding member for the imaging unit 14 As shown in Figures 5 to 8, a rectangular box-shaped space is provided in the lower part 11a of the case 11, in which the imaging section 15, recording section 16, and control section 17 that make up the imaging unit 14 are arranged and fixed in place.

[0022] 8, an imaging lens 19 for capturing moving or still images is exposed and disposed in a portion of the bottom of the case 11 corresponding to the imaging unit 15. Furthermore, a card slot 13 is provided in a side wall portion corresponding to the recording unit 16, into which a memory for storing captured image data can be attached or detached.

[0023] As will be described later, the imaging unit 14 is supplied with power from a power supply socket 2a of the lighting fixture 2 via a terminal 3c of the LED light 3.

[0024] B-2: Functions as an attachment part for LED light 3 3 to 7, a light insertion hole 12 having a diameter large enough to accommodate and hold the LED light 3 therein is formed in the upper portion 11b of the case 11, straddling both end portions of the case 11. One end of the light insertion hole 12 is an open end 12a, and the other end is a closed end 12b that is closed by a closing plate 20, which will be described next.

[0025] 12 and 14, the closing plate 20 is a disk body made of a thin resin plate, and is fitted and held in an annular groove-shaped closing plate holder 18 provided on the inner periphery of the closing end 12b of the light insertion hole 12, and is rotatable around its center. In the camera device 1 of this embodiment, as shown in FIG. 14, the closing plate 20 can be rotated within an angular range of +α to -α with respect to the center of the closing plate 20, i.e., the straight line L passing through the axis of the LED light 3.

[0026] On the other hand, as shown in Fig. 14, a pair of power supply blades 23 (see Fig. 9) are attached in parallel at a predetermined interval (i.e., the terminal interval of the LED light 3) on the closure plate 20. The power supply blade 23 is formed by overlapping and laminating a first blade 24 and a second blade 25, which will be described below.

[0027] 10, the first blade 24 is made of a vertically long rectangular thin copper plate, and has a hole 24b formed in its approximate center by cutting radially around a hole of a predetermined diameter and then cutting the remaining portion 24a at an angle of approximately 35 degrees. The first blade 24 also has three short locking claws 24d and one long protrusion 24c.

[0028] 11, the second blade 25 is made of a vertically long rectangular thin copper plate, and has a hole 25b formed in its approximate center by cutting radially around a hole of a predetermined diameter, cutting and raising the remaining portion 25a at an angle of approximately 30 degrees, and bending a predetermined range on the tip side of the second blade 25 so that it is approximately perpendicular to the surface direction of the second blade 25. The second blade 25 also has one long protrusion 25c.

[0029] The first blade 24 and the second blade 25 are stacked and fixed together with the hole 24b of the first blade 24 overlapping the hole 25b of the second blade 25, thereby forming the power feed blade 23. The overlapping holes 24b and 25b form the terminal insertion hole 21. The long protrusions 24c of the first blade 24 and the long protrusions 25c of the second blade 25, which are joined and fixed to each other, form a lead wire fixing portion 26, to which a power feed cable 27 to the imaging unit 14 is joined and fixed (see FIGS. 12 and 14).

[0030] As shown in Fig. 14, the pair of power feed blades 23 are fixed to the closure plate 20 so that the terminal insertion holes 21 face a pair of left and right rectangular holes 20a formed in the closure plate 20. The power feed blades 23 are fixed to the closure plate 20 by engaging the locking claws 24d on the first blade 24 side with the edges of the locking holes 20b on the closure plate 20 side, as shown in Fig. 14.

[0031] C: Power supply to the imaging unit 14 The LED light 3 is mounted between the power feeding side socket 2a and the non-power feeding side socket 2b of the lighting fixture 2. In this case, in the power feeding side socket 2a, as shown in Figures 12 and 14, each terminal 3c of the LED light 3 passes through a terminal insertion hole 21 of a power feeding blade 23 provided on the closure plate 20 and is joined to the socket 4 on the power feeding side socket 2a side. Therefore, when power is fed from the socket 4 to the LED light 3 side, power is simultaneously fed from the terminal 3c to the imaging unit 14 side via the power feeding blade 23.

[0032] Therefore, when installing the camera device 1, there is no need to provide a dedicated power supply means for the imaging unit 14, which reduces the installation cost of the camera device 1 and also increases the degree of freedom in the installation work, making it possible to reduce the installation cost.

[0033] D:Other (1) The camera device 1 of this embodiment is configured separately from the LED light 3 and can be installed as needed regardless of whether or not there are plans to replace the LED light 3. Therefore, compared to a camera device formed integrally with the LED light, for example, it is possible to provide a camera device that is more economical and versatile, and the operating costs of the camera device 1 can be kept low.

[0034] (2) In the camera device 1 of this embodiment, as described above, the closing plate 20 is attached to the end of the light insertion hole 12 of the case 11 so as to be rotatable around its axis. Therefore, although the circumferential attachment position of the LED light 3 relative to the lighting fixture 2 is determined by the position of the terminal 3c of the LED light 3, the relative position of the camera device 1 relative to the LED light 3 is allowed by the rotatability of the closing plate 20. Therefore, the orientation direction (imaging position) of the imaging lens of the camera device 11 can be changed by rotating it within a required angle range (the angle range of “+α to −α” shown in FIG. 14). As a result, the camera device 1 is highly versatile, and when the camera device 1 is used for security purposes, the effect is remarkable, such as being able to accurately photograph the desired location.
