Description

LIGHTING APPARATUS USING MAGNET

Technical Field

[1] The present invention relates to a lighting apparatus using a magnet which can be lighted with a low voltage power like a LED or a halogen lamp, and slides and is able to adjust a lighting angle, and in particular to a lighting apparatus using a magnet which comprises a lighting lamp assembly consisting of a line outlet formed of two parallel conductive cables, and a plug terminal engaged at both sides of a non- conductive magnet and made of a conductive magnetizing member (steel plate) wherein the lighting lamp assembly can freely slide on a line outlet so that lighting is possible at any place. Since the lighting lamp assembly is rotatable in all directions, a lighting angle can be adjusted, so that it is very efficient to light a certain object placed in a showcase or a certain indoor place.

[2]

Background Art

[3] Generally, a lighting lamp is formed of an incandescent lamp or a fluorescent lamp.

Here, the incandescent lamp is inexpensive but consumes a lot of power and generates high temperature heat, so that its life is short. The fluorescent lamp is able to decrease power consumption and has a longer life as compared to an incandescent lamp, but a price of the same is high.

[4] Since the above incandescent lamp and fluorescent lamp both use a high AC voltage like 110V or 220V, they may have electric shock accidents or fire accidents owing to a short circuit.

[5] In recent years, the use of a lighting lamp formed of a LED or halogen lamp, which is able to light with a lower DC voltage, increases. However, a LED and a halogen lamp need a certain structure that a plug is connected at an electric outlet or a socket. So, when a plurality of LEDs or halogen lamps are to be installed in a show case or an indoor, since the outlets or sockets are needed by the same number as the lighting lamps. In this case, a plurality of outlets or sockets are installed. It is needed to connect an electric cable to each outlet or socket, so that a wiring work needs a lot of time and workers. The installation cost increases. Since the LED and halogen lamps connected with a plurality of outlets or sockets are to be installed in a fixed state, they are not movable or a lighting angle cannot be adjusted. So, it is impossible to achieve an efficient lighting operation.

[31] In the drawings, reference numeral 1 is a line outlet, and 2 is a lighting assembly.

[32] The line outlet 1 comprises a nonconductive frame 11 having a channel shaped cross

section, and two cables 12a and 12b with parts being exposed. Both the cables 12a and 12b are connected with an electric cable from a power supply device 3 for supplying a relatively low power (below 50V, preferably 20-30V) so that a human body is not electrically shocked when being touched. Here, the power may comprise an adaptor for converting a high voltage into a low voltage or a DC battery.

[33] The nonconductive frame 11 of the line outlet 1 is made of a nonconductive material such as plastic and has a long length, so that it is cut when in use. As shown in the drawings, two cables 12a and 12b are exposed in part from both inner sides of the non- conductive frame 11 and are engaged in parallel for thereby conducting electricity externally inputted and are magnetized in magnetic fields, Namely, they are made of metallic materials which may attach to a material having a magnetic force.

[34] The lighting lamp assembly 2 is magnetically attached to two cables 12a and 12b engaged at the line outlet 1 in parallel, so that the lighting lamp 4 is turned on by electricity flowing to the both cables. In a state that the lighting lamp 4 is magnetically attach to both cables, it may slide in the longitudinal direction of the line outlet 1, and the lighting lamp 4 may rotate in the length and width wise directions of the line outlet 1 for thereby adjusting the lighting angle.

[35] Here, the lighting lamp assembly 2 comprises a nonconductive magnet 21 made of a plastic material which has a conduction function and a magnetizing function, plug terminals 22a and 22b which are magnetically attached to both sides of the non- conductive magnet and are made of steel materials for conducting electricity from the cables 12a and 12b, and connection links 24a and 24b which are electrically connected with the plug terminals 22a and 22b with one end of each being rotatably connected at both ends of a nonconductive bolt passing through the nonconductive magnet 21 without allowing the plug terminals to be short circuit. The other end (free end) of each connection link 24a, 24b is rotatably connected with each rotation terminal 25a, 25b. One end of each rotation terminal is rotatably inserted into the other end of each connection terminal 24a, 24b and is limited by a stop ring. The other end of each rotation terminal 25 a, 25b is electrically connected with each connection terminal 41a, 41b protruded from the lighting lamp 4 in loosened states.

[36] The nonconductive bolt 23 used for electrically connecting the connection links 24a and 24b to the plug terminals 22a and 22b via the nonconductive magnet 21 are made of plastic materials. An O-ring 26 is disposed between the nuts 23a and 23b assembled at both ends of the nonconductive bolts 23 and between the connection links 24a and 24b. Each connection terminal 41a, 41b of the nut 23a, 23b is inserted into a slit formed at each rotation link 25a, 25b and is fixed by an engaging member 27a, 27b. The engaging members 27a and 27b may be formed of bolts or rivets.

[37] Here, the lighting lamp 4 may be formed of a low voltage LED or halogen lamp. A

reflection shade 5, which surrounds the light transmission member 42, may be installed so as to enhance a lighting efficiency of light from the light emitting member (in case of LED, it is LED chip, and in case of halogen lamp, it is tungsten filament) installed in the interior of the light transmission member 42 of the lighting lamp 4. As shown in Figures 1 through 3, the reflection shade 6 is caught by a flange 43 formed at an end of the light transmission member 42 of the lighting lamp 4.

[38] In the embodiment as shown in Figure 4, the lighting lamp 4 is connected with each plug terminal 22a, 22b engaged at both side surfaces of the nonconductive magnet 21. The reflection shade 6, which surrounds the lighting lamp 4, surrounds the non- conductive magnet 21 and the plug terminals 22a and 22b engaged at both sides so that one end of each plug terminal 22a, 22b is protruded.

[39] In the embodiment of Figure 6, the lighting lamp 4 is installed in the interior of the angle adjusting casing 29 which is rotatable at a certain angle in all directions with the help of a spherical ball 291 rotatably inserted into a spherical groove 281 formed at a front end of the attaching casing 28 which surrounds the nonconductive magnet 21 and the plug terminals 22a and 22b attached at both sides. The connection terminals of the lighting lamp 4 are electrically connected with the plug terminals 22a and 22b installed in the interior of the attaching casing 28 via a wire hole 293 which passes through the connection part 291 and the spherical ball 292 of the angle adjusting casing 29.

[40] A concave spherical surface 44 shaped like a concave lens is formed at a front end of the lighting lamp 4, so that it is possible to transmit light from the light transmission member 42 in a certain direction. As a reflection layer is formed on an inner surface of the reflection shade 5 for reflecting light from the light transmission member 42, so that it is possible to transmit a full amount of light from the lighting lamp 4 in a forward direction for thereby enhancing a lighting effect.

[41] The operation of the present invention will be described with reference to the accompanying drawings.

[42] The line outlet 1 is installed at a product showcase or on a ceiling of an indoor space.

In case of the showcase, the lint outlet 1 is installed in the interior of the same in a vertical direction or a horizontal direction. In case of the indoor ceiling, at least one line outlet 1 is installed in parallel or in a rectangular shape. According to at least one line outlet 1 installed in the showcase or the indoor, an electrical cable from the power supply device 3 is connected with cables 12a and 12b at one end of one line outlet 1, so that it is possible to supply a relatively low DC voltage to each line outlet 1.

[43] A plurality of lighting lamp assemblies 2 are installed at regular intervals at the line outlet 1 which is installed in the showcase and the indoor for thereby performing a lighting operation.

[44] The embodiments of the present invention of Figures 1 through 3 will be described.

[45] In each lighting lamp assembly 2 installed at the line outlet 1, when the plug terminals 22a and 22b get closer to the cables 12a and 12b exposed to the line outlet 1, the plug terminals 22a and 22b magnetized by the magnetic force of the nonconductive magnet 21 are magnetically attached to the cables 12a and 12b. At this time, the plug terminals 22a and 22b are separately magnetically attached to the cables 12a and 12b in a state that they are electrically disconnected by the conductive magnet 21 and the nonconductive bolt 23, so that the electricity of positive and negative flowing via the cables 12a and 12b becomes conductive with the plug terminals 22a and 22b without short circuit. The electricity conducting with the plug terminals 22a and 22b is supplied to the lighting lamp 4 via the connection terminals 41a and 41b of the lighting lamp 4 connected with the rotation terminals 25 a and 25b via the connection links 24a and 24b, so that the lighting lamp 4 is turned on.

[46] The lighting device 1 magnetically attached to the cables 12a and 12b of the line outlet 1 can slide in the longitudinal direction that the cables 12a and 12b are parallel (refer to the arrow of Figure 2). In a state that the plug terminals 22a and 22b are magnetically attached to the cables 12a and 12b, the electricity of positive and negative keeps supplying to the lighting lamp 4 while the lighting lamp assembly 2 slides in the longitudinal direction of the line outlet 1. In this state, even when the installation position changes by sliding the lighting lamp assembly 2, the lighting lamp 4 keeps turned on all the time. The plug terminals 22a and 22b may be detached by a force stronger than the magnetic force of the nonconductive magnet 21 which allows a magnetizing attachment to the cables, so that it is possible to increase or decrease the installation numbers of the lighting lamp assemblies 2 installed at the line outlet 1.

[47] As shown in Figure 2, the lighting lamp 4 of the lighting lamp assembly 2 installed at the line outlet 1 can be rotatable in the left and right directions toward the longitudinal direction of the line outlet 2. At this time, the connection links 24a and 24b connected with the plug terminals 22a and 22b magnetically attached to both sides of the non- conductive magnet 21 may be rotatable in the left and right directions about the non- conductive bolt 23. As shown in Figure 3, the rotation terminals 25 a and 25b rotatably connected at the free end of each connection link 24a, 24b are rotatable in the left and right directions toward the width wise direction of the line outlet 1, so that the lighting lamp assembly 2 can rotate in all directions, whereby it is possible to light in a desired direction of the lighting lamp assembly 2.

[48] As shown in Figures 4 and 5, the lighting lamp assembly 2 is not able to rotate the lighting lamp 4 in all directions. However, in a state that the plug terminals 22a and 22b are magnetically attached to the cables 12a and 12b of both sides of the line outlet 1, it can move in a straight direction along the both cables. So, it is possible to light in the forward direction of the lighting lamp 4 without operating the lighting lamp 4 of

the lighting lamp assembly 2.

[49] As shown in Figure 6, the lighting lamp assembly 2 is straight moved along the cables 12a and 12b of the line outlet 1, and the angle adjusting casing 29 assembled to the front end of the attaching casing 28 can rotate in all directions at a certain angle, so that it is possible to adjust a desired lighting angle of the lighting lamp 4 attached to the interior of the angle adjusting casing 29.

[50]

Industrial Applicability

[51] As described above, the lighting apparatus comprises a LED or halogen lamp which is turned on with a low voltage. A user may be safe from an electric shock and a fire accident owing to a short circuit for thereby achieving a safety. Two cables extended from a power supply device, which supplies a low voltage, are simply connected with one end of a line outlet which is installed in a horizontal direction or a vertical direction in a showcase which shows various products and exhibited or on a ceiling or a wall of a market place which sells various products, so that electric power can be supplied to a plurality of lighting devices which are connected with a line outlet with a simple wiring work. The installation number of the lighting apparatuses at the line outlet can be selected without limits, and the sliding movement is possible. A lighting angle of the lighting lamp can be easily controlled. It is possible to effectively light toward a certain position in a showcase or a market place.

[52] As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
