Description

  The present invention relates to an LED lighting device that uses an LED (light emitting diode) to form a light source that is elongated in the longitudinal direction, and particularly relates to an LED lighting device that is additionally equipped with a mounting tool so as to be easily mounted on a construction site or the like.

  As a light source for illumination, a straight tube type fluorescent lamp has been mainstream for a long time. However, in recent years, a straight tube type LED lamp in which an LED is disposed as a light source in a straight tube has been developed from the viewpoint of energy saving and life. It was. This straight tube type LED lighting lamp is obtained by inserting a circuit board on which a large number of LEDs are mounted inside an elongated cylindrical translucent tube formed of glass or resin. In order to provide compatibility with a conventional straight tube fluorescent lamp, a lighting circuit that emits an LED is mounted on a circuit board, and the same base as the conventional fluorescent tube is attached to both ends of the translucent tube (for example, Patent Literature 1 and 2).

Such a straight tube type LED lamp is compatible with a conventional straight tube fluorescent lamp and is convenient for indoor lighting. However, there is a problem in using such straight tube type LED lighting for temporary lighting at construction sites such as tunnel construction, water and sewage construction, bridge construction work, and festival venues. Glass or resin cylindrical translucent tubes are fragile in these places. In addition, a large number of illumination lamps are required in such a place, but it is normal that there are no attachment points and fixtures for a large number of temporary illumination lamps. In the case of a compatible straight tube type LED illuminating lamp, it is not easy to mount and fix it, and there are many difficulties in wiring a temporary cable that supplies power to them.

JP 2011-165634 A Utility Model Registration No. 3142651

  The present invention has been made to solve such problems of the prior art, and the problem is an LED lighting apparatus suitable for use in temporary lighting required at a construction site or a temporary entertainment venue. Another object of the present invention is to provide an LED lighting apparatus that is not easily broken, is easy to mount, and can easily supply power to a large number of mounted lighting lamps.

  The device according to claim 1 for solving the above-mentioned problem is an LED lighting apparatus having an elongated light source, and is an elongated rectangular plate-like wiring board provided with two power lines for supplying plus and minus power. A plurality of light emitters connected in parallel on the wiring board so as to emit light upon receiving power supply from the power line, and two wiring lines each including the connector electrode. A pair of connectors of the same shape arranged on both outer sides of the board, a power cable for directly connecting the same electrodes of the connectors on both ends, and the LED lighting fixture body composed of the wiring board, the connector, and the power cable on the wall surface, etc. 2 to 3 attachments for attachment to the power supply, the power supply line is supplied with power from one of the pair of connectors, and each attachment is provided with a plurality of attachment holes. It consists of a rectangular mounting plate, a binding band, and a magnet. The LED luminaire body is bound by a binding band and fixed to the mounting plate using the mounting hole of the mounting plate. It is fixed at one end in the longitudinal direction of the mounting plate. The LED lighting fixture is characterized in that the magnet for attaching to an iron wall surface or the like is attached to the opposite surface of the LED lighting fixture main body.

  According to such a configuration, since a thicker electric wire can be used for the power cable directly connecting the electrodes of the left and right connectors, the LED lighting apparatus is cascade-connected via the wiring cable in the middle, and the downstream side LED lighting apparatus is connected. Can supply a large current. Thereby, many LED lighting fixtures can be lighted all at once. Moreover, since the left and right connectors of the LED lighting apparatus are the same and symmetrical, the same and symmetrical connectors can be used for the connectors at both ends of the wiring cable when two LED lighting apparatuses are connected in cascade. For this reason, when cascading a large number of LED lighting fixtures using a wiring cable, there is no need to worry about whether the left and right connectors of the LED lighting fixture and the wiring cable are male or female, and cascading is easy. Can be done. Furthermore, since the light emitting part does not use a glass tube or a resin tube, it is resistant to impacts and is suitable for temporary lighting in places where impacts are easily applied, such as construction sites and entertainment venues. In addition, since the LED lighting fixture is provided with an attachment with a magnet, it can be easily attached to an iron wall, ceiling, iron formwork or the like, which is often used in construction sites. If there is no iron wall, etc., a small iron plate piece can be easily attached using a magnet by temporarily attaching it with an adhesive. Furthermore, since adjacent LED lighting fixtures can be connected by a wiring cable with a connector that uses connectors at both ends of the LED lighting fixtures, when the distance between the LED lighting fixtures is short, there is an advantage that a support for supporting these wiring cables is not required. Also have.

  Further, the invention according to claim 2 is the LED lighting apparatus according to claim 1, wherein the mounting plate is hooked to the end of the mounting plate opposite to the one end in the longitudinal direction where the magnet is mounted. The LED lighting apparatus is characterized in that a round hole for hanging is formed.

  According to such a configuration, the LED lighting apparatus can be easily attached by using the round hole of the rectangular attachment plate by attaching the hook to the wall surface.

  The invention described in claim 3 is the LED lighting apparatus according to claim 2, wherein the magnet in the mounting plate is eliminated.

  When a hook is used to attach to a place where the magnet is not attracted, the magnet is unnecessary, so that the product cost can be reduced by eliminating the magnet.

  Hereinafter, an embodiment of an LED lighting apparatus according to the present invention will be described with reference to the drawings. FIG. 1 is an external view of a light emitting surface side of an LED lighting apparatus 1 according to the present invention, and FIG. 2 is an external view of the back side thereof. The LED lighting device 1 includes a lighting main body 2 and a pair of connectors 3 arranged on both outer sides of the lighting main body 2. The illumination main body 2 has an elongated shape with a substantially rectangular cross section. The length is about 650 mm. On the light emitting surface side, 60 light emitting bodies 6 each consisting of a series connection circuit of an LED (light emitting diode) 4 and a resistor 5 are attached at equal intervals.

  FIG. 3 is an electrical connection diagram of the LED lighting apparatus 1. A pair of connectors 3 on both outer sides are connectors having the same shape and the same configuration. Each connector 3 has two connector electrodes, both of which are male, or both female, or one is male and the other is female. Two power supply wires 7a and 7b (power supply cables) are stretched between two connector electrodes at the same position of the left and right connectors 3. The power supply wirings 7 a and 7 b are used exclusively for transferring the power supplied to one connector 3 to the other connector 3. When the connector electrode is a combination of a male type and a female type, the left and right male types and the female types are connected by power supply wirings 7a and 6b.

  The light emitter 6 is composed of six LEDs (light emitting diodes) 4 and a resistor 5 connected in series, and is mounted on an elongated wiring board 9. On the wiring board 9, two power supply wirings 10a and 10b are provided as printed wirings. The power supply wirings 10a and 10b are connected to the power supply wirings 7a and 7b near one connector 3 by lead wires 13, and receive positive and negative power supply therefrom. The 60 light emitters 6 are connected in parallel between the power supply wires 10a and 10b.

  FIG. 4 is a longitudinal sectional view of a portion where the light emitter 6 is attached, and FIG. 5 is a plan view showing an attachment state of the LED 4 and the resistor 5 constituting the light emitter 6 on the wiring board 9. On the elongated wiring board 9, power supply wirings 10a and 10b by copper foil printed wiring are stretched, and the LED 4 and the resistor 5 are connected in series between them. The base ends of the power supply wires 10a and 10b are connected to the power supply wires 10a and 10b near one connector 3 by two lead wires 13. The wiring board 9 is attached inside an aluminum radiator 15 having a concave cross section. A transparent silicon resin 16 is filled up to the height of the upper ends of both sides of the concave aluminum radiator 15 on the power supply wirings 10 a and 10 b and the light emitter 6. Furthermore, a coating film 13 made of a transparent silicon resin is formed so as to cover the entire surface of the aluminum radiator 15, the transparent silicon resin 16, and the light emitter 6 in order to prevent dust and water from entering. The entire section has a width of about 18 mm and a thickness of about 4 mm.

  The two power supply wires 7a and 7b that directly connect the left and right connectors 3 are passed through a corrugated conduit 20 disposed on the back side of the aluminum radiator 15 as shown in FIG. The corrugated conduit 20 is fixed to the aluminum radiator 15 by binding bands 21 arranged at several places. Moreover, the transparent heat-shrinkable tube 22 which covers the whole illumination main-body part 2, the corrugated conduit 20, the two power supply wirings 7a and 7b, and the two lead wires 13 is attached to the both ends of the illumination main-body part 2, Prevents ingress of dust and water from the edge.

  The LED lighting fixture 1 of this embodiment is a lighting fixture suitable for using in the construction site etc. which require many lighting. In order to connect a large number of LED lighting fixtures 1 and perform power supply, the LED lighting fixtures 1 connected in cascade are connected by a wiring cable 25 as shown in FIG. The wiring cable 25 has a connector 26 fitted to the connector 3 of the LED lighting device 1 at both ends, and a cable is connected between them. The wiring cable 25 may be passed through the corrugated conduit 20 for protection. The left and right connectors 26 have the same shape and symmetry corresponding to the connector 3 of the LED lighting apparatus 1. As shown in FIG. 7, the connector 26 of the wiring cable 25 is fitted into one connector 3 of the LED lighting apparatus 1, and the connector 26 of another wiring cable 25 is fitted into the other connector 3 of the LED lighting apparatus 1. By repeating this, a large number of LED lighting fixtures 1 are connected in cascade. Then, positive and negative power is supplied from the DC power source to the connector 26 of the first wiring cable 25. As a result, power is supplied to all the LED lighting fixtures 1 connected, and all the light emitters 6 are turned on.

  FIG. 8 is a plan view of the LED lighting apparatus 1a to which the mounting tool 30 for mounting the LED lighting apparatus 1 having such a configuration on a wall surface or the like is added. The attachment tool 30 is attached to 2 to 3 pieces in the longitudinal direction of the LED lighting apparatus 1. The attachment tool 30 includes an attachment plate 32 to which a magnet 31 shown in (1) of FIG. 9 is attached, and a binding band 33 shown in (2) of FIG. The attachment plate 32 is a long and narrow rectangular plate made of synthetic resin, and a magnet 31 is fixedly attached to one surface at one end in the longitudinal direction. The attachment plate 32 is formed with at least two attachment holes 34 that are used when the LED lighting apparatus 1 is tied and fixed to the attachment plate 32 by the binding band 33.

  10 is a cross-sectional view taken along line AA in FIG. The LED lighting device 1 (LED lighting device main body) including the corrugated conduit 20 through which the lighting main body portion 2 and the two power supply wires 7 a and 7 b attached to the back surface of the lighting main body portion 2 are passed is bound to the mounting plate 32 with a binding band 33. When the LED lighting apparatus 1 is mounted at a high position on the wall surface, the light emitting surface of the lighting body 2 is slightly tilted with respect to the surface of the mounting plate 32 so that the light from the lighting body 2 is directed obliquely downward. It is good to fix.

  When the attachment surface is made of a metal that attracts the magnet 31, the LED lighting apparatus 1a including the attachment 30 can be easily attached by attracting the magnet 31. When the wall surface is not made of a material that adsorbs the magnet 31, as shown in FIG. 11, a thin thin iron plate 40 is attached to the wall surface with an adhesive, and the magnet 31 is adsorbed thereon to attach the LED lighting apparatus 1 a. Install. Instead of the thin iron plate 40 having a small width, an iron plate piece 41 large enough to attract the magnet 31 may be used as shown in FIG.

  As shown in FIG. 9 (1), a round hole 35 is formed at the end of the attachment plate 32 opposite to one end in the longitudinal direction where the magnet 31 is attached. Instead of attaching the magnet 31 by attracting it, the LED lighting apparatus 1a can be attached to the wall surface to which the hook is attached using the round hole 35. FIG. 13 is a cross-sectional view in which a hook 43 is attached to a wall surface 42 with an adhesive, and the hook 43 is hooked through a round hole 35 of the mounting plate 32. In this case, if the magnet 31 is not required, the magnet 31 may be omitted as shown in FIG. The posture of the LED lighting apparatus 1a when hung as shown in FIG. 13 and FIG. 14 is turned 180 ° from the posture shown in FIG. 11, and the left and right connectors are switched. However, in the LED lighting apparatus 1a of the present embodiment, the left and right connectors are configured symmetrically, so even if the left and right are interchanged, the wiring cable 25 with a connector that connects the LED lighting apparatuses 1a is not reversed left and right. It can be connected as it is.

  In the LED lighting apparatus 1a provided with the LED lighting apparatus 1 and the mounting tool 30 of the present embodiment described above, dedicated power wirings 7a and 7b are stretched between the left and right connectors 3, and are supplied to one connector 3. Most of the remaining power is transferred to the next LED lighting apparatus 1 through the power wirings 7a and 7b except for the self-consumption. Since the power supply wirings 7a and 7b are configured by dedicated wires rather than printed wirings, thick wires having a large current capacity can be used. In construction sites, several tens of LED lighting fixtures may be required. When several tens of wires are connected, a large current flows through the power supply wiring of the LED lighting apparatus 1 close to a DC power supply. If the power supply wiring is composed of printed wiring, it is impossible to flow such a large current. Since the LED lighting fixtures 1 and 1a of the present embodiment span the dedicated power supply wires 7a and 7b, a large current can be passed using a thick electric wire. For this reason, cascade connection of many LED lighting fixtures 1 is easy.

  Moreover, in the LED lighting fixture 1 of this embodiment, the same and symmetrical connector is used for the connector 3 on either side. Therefore, the same and symmetrical connectors can be used for the left and right connectors of the connector 26 of the wiring cable 25. Therefore, when cascading a large number of LED lighting fixtures 1 using the wiring cable 25, there is no need to worry about whether the left and right connectors of the LED lighting fixture 1 and the wiring cable 25 are male or female. Connection work can be easily performed. Furthermore, since the luminous body 6 is not enclosed in a glass tube or a resin tube, it has an advantage that it is not broken by a slight impact.

  Moreover, in the LED lighting fixture 1a provided with the attachment tool 30 of this embodiment, since the magnet 31 is attached to the attachment tool 30, if it is a wall surface which a magnet adsorb | sucks, it can attach easily as it is. In the case of a wall surface on which a magnet is not attracted, a thin iron plate with a narrow width is affixed, or a small iron plate piece is affixed only to a portion where the magnet 31 is adsorbed, and the magnet 31 is adsorbed thereon to be easily attached. it can. Moreover, it can replace with making it adsorb | suck with a magnet, affixing and attaching the hook 43 to a wall surface, and also attaching to it. Because of these various advantages, the LED lighting apparatus 1a provided with the mounting tool 30 of the present embodiment is suitable as temporary lighting at construction sites such as tunnel construction, water and sewage construction, bridge construction, and festival venues.
