Description

The present invention relates to an LED light module and a lighting device particularly suitable as a light source for a lighting device such as a stand-type or pendant-type lighting device or a sign pole.

In the past, the light sources for lighting equipment used in homes were roughly divided into two types: incandescent bulbs and fluorescent bulbs, but from around 2010, light sources with light emitting diode (LED) elements lined up in a straight line have been introduced. As the technological innovation of light sources progresses, they are now widely used (see Patent Documents 1 and 2).

Recently, as a light source using LED, a wiring pattern is formed on one side of a strip-shaped base film, and an LED light tape (hereinafter referred to as , LED tape) is also commercially available at relatively low cost, and can be used as lighting by pasting the LED tape in a line on the other side of the base film using adhesive tape, etc. to the installation area such as a wall. There have also been many proposals for using fluorescent lamps, such as installing them in the case of lighting equipment instead of conventional fluorescent lamps.

LED tape can be powered by 5V, 12V, or 24V, so it can be expected to significantly reduce power consumption and is easy to handle. When using an LED tape as a light source that irradiates light uniformly toward the outer circumference of a lighting device such as a pendant-type lighting device or a sign pole with a cylindrical main body case, a bone is used to hold the light source. Further structural improvements are required, such as what materials to use.

The present invention solves this problem, and is composed of simple assembly work of component parts.It takes advantage of the inherent advantages of LEDs, such as light directionality and low cost, while also eliminating differences in light intensity. To provide an LED light module constituting a light source that uniformly irradiates light toward the outer periphery of an exterior member such as a shade or a main body case with a design, and a lighting device equipped with the LED light module. With the goal.

In order to achieve the above-mentioned object, the LED light module of the present invention has a plurality of LEDs arranged in the longitudinal direction, an LED tape wired so as to be electrically conductive, and a tip end formed as an arcuate curved part. A flat bar on which the tape is pasted is attached to the center of the light source, with the arcuate curved part protruding outward and the base end fixed to the distal end of a fixing member formed in the shape of a tube shaft. It is characterized by comprising three or more light source units arranged at equal intervals around the axis.

An LED light module with this configuration is manufactured by applying a voltage to the LEDs of the LED tape attached to three or more flat bars evenly distributed around the central axis of the light source. It becomes possible to distribute light to (excluding the proximal end side). At that time, since the LED light is attached to the arcuate curved part provided at the tip of the flat bar that makes up the light source unit, the tip can also distribute light in the direction of the center axis of the light source, and the light bulb can be placed at the tip. In the middle part, the light is distributed from the central axis of the light source to the sides, and it is possible to obtain illumination similar to that of a plurality of fluorescent lamps. In other words, since the LEDs attached to the LED tape are small and spaced closely, they can be used as a linear light source. Furthermore, it is possible to obtain the effect that there is no unevenness in brightness. In addition, since the LED light module with this configuration can emit light by being supplied with power from one side (fixed member side), it can be held in a cantilevered position, and it is possible to prevent shadows from appearing around the circumferential axis of the light source. .

Further, a short flat bar on which the LED tape is attached on the outer surface is fixed to the distal end of a fixing member whose base end is shaped like a tube shaft, and the bar is rotated around the central axis of the light source. The light source unit is the same as the light source unit and arranged at equal intervals, and the distal end can be connected by inserting the base end of the fixing member of the light source unit or the base end of the fixing member of another extended light source unit. The present invention is characterized by comprising an extended light source unit formed in the form of an extended light source unit.

In an LED light module having this configuration, one or more extension light source units are sequentially inserted into the light source unit to extend the entire length of the flat bar to which the LED tape is attached, constituting the light source unit. It can be easily adjusted by connecting them.

The lighting device of the present invention is a lighting device equipped with the above-mentioned LED light module, in which the light source unit or the extension light source unit is fixed in an uncoupled manner in a fitting hole drilled in the surface on which the light source unit is disposed. The light source unit may be provided with a base member into which a proximal end portion of the member is inserted and which fixes the light source unit; and an exterior member that is disposed on the base member and decoratively covers the light source unit and the extended light source unit. Features.

The lighting device with this configuration is extremely simple in that the LED light module can be incorporated into the base member, and the base member is positioned above the light source unit, the light source unit is suspended below the base member, and the desired decorative exterior member is attached as the light source. You can create a pendant-type lighting fixture by arranging it around the area, or connect the light source unit and the extension light source unit to ensure a long light source that can distribute light all around the base member placed on the floor, etc. By placing a cylindrical body case as an exterior member, it can be used like a sign pole.

As mentioned above, according to the present invention, the component parts can be easily assembled, the length of the light source can be easily adjusted, and the light directivity and low cost that are inherent to LEDs can be easily adjusted. Taking advantage of advantages such as cost, it is possible to easily assemble and provide an LED light module that constitutes a light source that uniformly irradiates light toward the outer circumference of an exterior member, and a lighting device equipped with the LED light module. .

Hereinafter, the LED light module 1 of the present invention will be explained using FIGS. 1 to 8.

As mentioned above, a plurality of LED light modules 1 of the present invention are installed on a tape-shaped base material 3 as a light source for a lighting device 101 such as a pendant lighting fixture, a table lamp, a floor lamp, or a sign pole. This jig uses a commercially available LED tape 2 in which LED elements (hereinafter simply referred to as LEDs) 4 are arranged in the longitudinal direction, and each LED 4 is wired so as to be energized and integrated with resin.

The LED light module 1 includes a light source unit 6 that is supported on one side using a flat bar 5 on which the LED tape 2 is attached as an aggregate. The length dimension of the aggregate corresponds to the length dimension of the light source of the LED light module 1. Further, the aggregate may be composed of only the light source unit 6 (see the first embodiment, FIG. 1), or the light source unit 6 may include one or more extended light source units (see FIG. 7), as described later. , see FIG. 8) in some cases (see second embodiment, FIG. 6).

First, the light source unit 6 of the LED light module 1 of the first embodiment will be explained. The fixing member 11 is formed in the shape of a short circular tube shaft shown in FIGS. 2(A) and (B), and the fixing member 11 shown in FIGS. It has three flat bars 5 fixed at equal intervals to the outer peripheral surface of the fixing member 11 as shown in A) and (B). In this embodiment, each flat bar 5 is made of aluminum with heat dissipation properties, has a short width, has a flat plate shape, is formed with some flexibility, and has a length corresponding to the light source. The tip is formed as an arcuate curved portion 12 . As shown in FIG. 1, each flat bar 5 has its proximal end positioned at equal intervals on the outer circumferential surface of the distal end side of the fixing member 11, with the arcuate curved portion 12 protruding outward from the light source. It is arranged. In this embodiment, as a means for fixing the flat bar 5 and the fixing member 11, the fixing screw holes 13 formed in advance in the base end of the flat bar 5 and the fixing member 11 are aligned, and the screws 14 Although a means of fixing using a method is adopted, the fixing means is not limited to this method.

The aggregates assembled in this way form the top of the light source by bringing the tips of each flat bar 5 forming the arcuate curved portion 12 into abutment. The surface of each flat bar 5 is covered with an adhesive (not shown) such as double-sided tape or the like, from the distal end forming the arcuate curved portion 12 to the proximal end fixed to the fixing member 11. The wiring 7 of the LED tape 2 is drawn into the tube of the cylindrical fixing member 11 and pulled out from the open base end side so as to be connectable to an external power source. The central axis of the circular tubular fixing member 11 becomes the central axis of the light source using this light source unit 6. With this configuration, the light source unit 6 can be supported on one side with the fixing member 11 side as the base.

In this embodiment, as shown in FIG. 2, the fixing member 11 is a small-diameter (about 15 mm in diameter) formed in the shape of a circular tube shaft, but the fixing member 11 is not limited to the circular tube shape. For example, it may be a hexagonal ring. Further, even if it is annular, it is also possible to use a large diameter one whose diameter (width dimension) corresponds to the size of the light source unit 6. Furthermore, the number of flat bars 5 fixed to the fixing member 11 can also be increased depending on the size of the light source unit 6. Note that FIG. 4(A) shows a state in which three flat bars 5 are arranged on a circular tubular fixing member 11 with a diameter of 15 mm, and FIG. 11 shows a state in which five flat bars 5 are arranged.

That is, as shown in the light distribution curve diagram of FIG. 5, assuming that the effective directivity angle of the LED 4 is 120°, at least three flat bars 5 with LED tapes are arranged at equal intervals on the outer circumference of the light source. This makes it possible to distribute light uniformly around the entire circumference of the light source. When the diameter of the fixing member 11 is large, an LED tape 2 equipped with LEDs 4 with a large amount of light may be used, or the diameter of the fixing member 11 may be increased (significantly), and a flat bar 5 disposed around the outer circumference of the fixing member 11 may be used. By increasing the number of lights, uniform light distribution around the entire circumference of the light source can be ensured.

Further, an annular intermediate fixing member (not shown) is separately prepared as a part of the aggregate, and the intermediate part in the length direction of each flat bar 5 is fixed to the outer periphery of the intermediate fixing member at equal intervals, and the light source is The aggregate of unit 6 may be reinforced. This intermediate fixing member will be explained in more detail in the second embodiment.

In the LED light module 1 having this configuration, a voltage is applied to the LEDs 4 of the LED tape 2 attached to three or more flat bars 5 evenly distributed around the central axis of the light source, so that the lighting device 101 can be activated. It becomes possible to distribute light all around the light source. In other words, the arcuate curved portion 12 at the tip of the flat bar 5 constituting the light source unit 6 is shaped to give an angle to the LED 4, and the LED light is attached to the arcuate curved portion 12. The light emitted from the arcuate curved portion 12 can be distributed outward in the direction of the central axis of the light source, and by distributing the light from the LEDs 4 disposed in the middle part of each flat bar 5, the light can be distributed outward in the direction of the central axis of the light source. You can distribute light around you. In addition, since the LED 4 tape 2 light can be powered by 5V, 12V, or 24V, it goes without saying that a significant reduction in power consumption can be expected. Furthermore, by using the aluminum flat bar 5, which has a high heat dissipation effect, as the aggregate, it is possible to suppress a decrease in the luminous efficiency of the LED due to heat accumulation.

Next, the four-LED light module 1 of the second embodiment shown in FIG. 6 will be described. As described above, the LED4 light module 1 of the second embodiment is constructed by connecting the light source unit 6 of the first embodiment with the extended light source unit 51 shown in FIG.

The extension light source unit 51 includes flat bars 5 that are the same as the light source unit 6 and have the same short width as the light source unit 6, and the base end of each flat bar 5 is arranged at equal intervals on the outer peripheral surface of the tip side. It has an extension fixing member 52 formed in the shape of a short shaft and intermediate fixing members 53 fixing the longitudinal intermediate portion of each flat bar 5 to the outer peripheral surface at equal intervals.

Although the extension fixing member 52 has substantially the same configuration as the fixing member 11 of the first embodiment and its explanation will be omitted, the intermediate fixing member 53 is formed in an annular shape in this embodiment, as shown in FIG. , are arranged at a position spaced apart from the distal end of each flat bar 5 by at least the non-disposed length dimension of the flat bar 5 at the proximal end of the fixing member 11. Thereby, by inserting and fitting the proximal end of the fixing member 11 of the light source unit 6 by using the part surrounded by the tip of each flat bar 5 as the insertion space 54 on the central axis of the light source of the extended light source unit 51, The flat bars 5 disposed at equal intervals on the outer periphery of the fixing member 11 and the flat bars 5 disposed on the extension fixing member 52 can be connected so as to butt each other. Note that the intermediate fixing member 53 is formed into a hollow annular shape in consideration of the heat dissipation effect of the light source unit 6, and may be a solid member.

By connecting the light source unit 6 and the extension light source unit 51, the proximal end and the distal end of the flat bar 5 disposed on each are matched to correspond to the length of the light source, and the length of each flat bar 5 is matched. The LED tape 2 is coated with an adhesive such as double-sided tape on the surface from the distal end forming the arcuate curved portion 12 of the light source unit 6 to the proximal end fixed to the extension fixing member 52 of the extended light source unit 51. (not shown). The wiring of the LED tape 2 is drawn into the tube of the cylindrical extension fixing member 52, and is pulled out from the open base end side so as to be connectable to an external power source.

The extended light source unit 51 can be formed into a plurality of different elongated lengths or a plurality of the same length, and can be used in combination with the light source unit 6 as appropriate to create a flat surface on which the LED tape 2 is pasted. The total length of the bar 5 can be adjusted to any length according to the light source of the LED light module 1.

Next, the illumination device 101 of the present invention equipped with the above-mentioned LED light module 1 will be explained using FIGS. 9 to 11. The lighting device 101 of the present invention includes a base member 103 having a fitting hole 102 formed in the center of the surface (top surface in this embodiment) on which the light source unit 6 is arranged. Although the base member 103 shown in FIGS. 9 to 11 has a rectangular shape outside the plane, the shape is not particularly limited.

The fitting hole 102 is formed so that the fixing member 11 of the light source unit 6 or the proximal end of the extension fixing member 52 of the extended light source unit 51, which is formed in the shape of a tube shaft, can be inserted into the fitting hole 102. Alternatively, the base end portion of the extension fixing member 52 can be fixed on the back side of the base member 103, that is, on the side opposite to the surface on which the light source unit 6 is disposed. A wiring hole 104 is formed in the fitting hole 102 to draw the wiring 7 of the LED tape 2 into the inside of the back side of the base member 103. It is configured to be connected to a power source (not shown) and to be turned on/off by turning on/off a switch (not shown).

Furthermore, in this embodiment, the mounting surface of the light source unit 6 of the base member 103 is configured as a stepped portion 110 having a convex central portion. This stepped portion 110 has a shape into which the lower end opening of a shade 120, which is an exterior member of the illumination device 101, is fitted.When the shade 120 is fitted to the stepped portion 110, the stepped portion 110 is fixed by a fixing means. It is fixed to the side wall 111. Specifically, fixing screw holes 13 formed in advance on the side wall 111 of the stepped portion 110 and the vicinity of the lower end of the shade 120 are aligned and fixed using screws 14, but the fixing means is not limited to this method. Not exclusively.

The illumination device 101 having such a configuration can be used as a pendant type of illumination by suspending the light source unit 6 below the base member 103 and arranging a desired decorative exterior member (shade 120) to surround the light source. By connecting the light source unit 6 and the extension light source unit 51 together as a fixture or by connecting the light source unit 6 and the extension light source unit 51 to secure a long light source that can distribute light all around, a cylindrical main body case is attached as an exterior member to the base member 103 placed on the floor or the like. By placing it in place, it can be used like a sign pole.

Note that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention. For example, it is also possible to attach a cylindrical grip portion that covers the fixing member 11 portion of the light source unit 6 and use it as a guide rod used for traffic guidance. Even in that case, the LED light module 1 of the present invention can easily be set to any length, and can distribute light all around the light source to ensure good visibility.
