Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a collective LED unit having a connector for facilitating wiring between the unit and a signboard or panel body.

[0002]

2. Description of the Related Art A plurality of light emitting diodes (hereinafter referred to as LEDs)
LED unit is mainly used as a light source (large outdoor LED lamp) for signs / advertising towers, road traffic signs, airport / railway related guide lights, etc. in urban areas, and this unit is generally used. It is as shown in FIG. This unit 50, as shown in FIG.
A plurality of (here, 40) LEDs 53 on the front surface of 1.
However, they are supported by the sealing resin 52 with their heads (resin mold parts) aligned and at appropriate intervals. In this example, 16 of the 40 LEDs 53 are red LEDs 5
3a (see the shaded area in the figure), 24 green LEDs 5
3b, and these two-color LEDs 53a and 53b are arranged according to a predetermined light emission pattern.

The 40 LEDs 53 have a harness 55 having terminals 56 as shown in FIG. 5 in order to connect to an LED control board (not shown) provided on a signboard or a panel body.
Extends from the case 51, or a similar harness extends from the signboard or panel body side.

[0004]

In the unit 50 as described above, the LED 53 is generally connected to the conductor pattern of the substrate (not shown). When the harness is provided on the unit 50 side, the harness is soldered to the substrate. When the wiring board is attached to the signboard or the panel body, the harness is soldered to the control board of the signboard or the panel body, and then the terminals of the harness are inserted into the unit 50 or a predetermined portion of the signboard or the panel body. 50 is electrically connected to the signboard or panel body.

However, in any case, when the unit is connected to the signboard or the panel body by using the harness,
It is necessary to perform wiring by using a wire material such as a lead wire on the unit side, the signboard, or the panel body side, which requires time and effort such as soldering at the time of wiring. In particular, on the signboard or panel body side, since the circuits are wired by a large number of wires, the inside of the signboard or panel body becomes complicated. Such trouble of wiring and complexity of the signboard or the inside of the panel body become more remarkable as the number of LEDs used increases.

Therefore, an object of the present invention is to provide a collective LED unit in which the trouble of wiring and the complexity of the signboard or the panel main body are eliminated.

[0007]

To achieve the above object, the collective LED unit of the present invention comprises a plurality of LEDs arranged in a case so that light is emitted from the front side of the case. A collective LED unit to be attached to a signboard or panel body, characterized in that a corresponding connector for connecting to a connector provided on an LED control board of the signboard or panel body is provided on the back side of the case. Is.

Since this unit has a connector in place of the conventional harness, a connector is also provided on the LED control board of the signboard or panel body in correspondence with the connector of the unit, so that the unit can be mounted on the signboard or panel body. At the same time as mounting, it becomes possible to connect the unit side connector to the signboard or panel body side connector. If you connect the unit and the signboard or panel body with the connector, you will not have to worry about wiring, and there is no need to wire using a wire even inside the signboard or panel body.
The inside of the signboard or panel body becomes simple.

The connector provided in the unit is not particularly limited, and a male connector or a female connector may be used, but a pin header is preferably used in view of the ease of connection to the signboard or the panel body. Is. Of course, a corresponding type (male or female) connector is provided on the LED control board of the signboard or the panel body.

EXAMPLES The collective LED unit of the present invention will be described below based on examples. A front view of the unit according to the embodiment is shown in FIG. 1, a rear view is shown in FIG. 2, and a side view seen from an arrow A in FIG. 1 is shown in FIG. In this unit 10, from the front side of the case 11, the head of the LED 12 (resin mold part)
So that all of them appear (12 in this case).
ED12 is grouped together, 16 bundles of LEDs 12 in total
Are arranged in a matrix direction, and are fixed and supported by the sealing resin 13 at that position. 12 LEs in each bundle
D12s are spaced from each other as shown. In this embodiment, the LEDs 12 emit two colors, red and green, and the red and green LEDs 12 are arranged according to a predetermined light emitting pattern. Also, case 1
From the front side to the back side of 1, the four screw hole portions 1 for screwing the unit 10 to the signboard or the panel body.
4 are formed.

As can be seen from FIG. 2, a substrate 20 is provided on the back side of the case 11, the substrate 20 has a predetermined conductor pattern, and all the LEDs 1 are provided in this conductor pattern.
2 are connected according to the light emission pattern. Furthermore, the pin header 21 is mounted on the board 20 as a male connector having 36 pins 22, and the number of pins 22 is the same (18).
They are arranged in two rows each, and project from the back side of the case 11 (see FIG. 3). Further, on the back side of the case 11, a positioning pin 23 useful for attaching the unit 10 to a signboard or a panel body is provided in a protruding manner at a position shown in FIG. 2, and a packing 24 having a shape as shown in FIG. 2 is provided. There is.

The unit 10 constructed as described above is attached to a signboard or a panel body, and this attachment is performed as shown in FIG. That is, in the housing (for example, an iron plate) 31 of the signboard or the panel body, the unit 1
An LED control board 33 is attached to the back side (inside of the signboard or the panel body) of the mounting portion of 0 via a spacer 32, and the pin header 2 of the unit 10 is attached to the control board 33.
The female connector 34 corresponding to 1 is mounted.

Therefore, if a screw is passed through the screw hole portion 14 of the unit 10 and the unit 10 is fixed to the front side of the iron plate 31 (outside of the signboard or the panel body) by this screw, the pin 22 of the pin header 21 simultaneously becomes a female connector. Then, the pin header 21 and the connector 34 are connected to each other. In this way, if the connector is used to connect the unit 10 to the signboard or the panel body, it is not necessary to solder the harness to the unit 10 or the signboard or the panel body, and wiring work can be saved. Moreover, even inside the signboard or the panel body, it is not necessary to circulate the circuit using the wire material such as the lead wire, and the inside of the signboard or the panel body can be neatly organized.

In the unit 10 shown in the above embodiment, the louver for blocking the direct light from the LED 12 is not attached to the front side of the case 11, but it goes without saying that it may be a unit with a louver. is there.

[0015]

As described above, the set type L of the present invention is used.
The ED unit has the following effects because the corresponding connector for connecting to the connector provided on the LED control board of the signboard or the panel body is provided on the back side of the case. (1) Since the unit is connected to the signboard or the panel body by the connector, it is possible to save the trouble of wiring the unit and the signboard or the panel body. (2) Since it is not necessary to perform wiring inside the signboard or the panel body using a wire material, the inside of the signboard or the panel body is not complicated, and the inside can be simply arranged. (3) As shown in the embodiment, if the unit is attached to the signboard or the panel body and the connectors of both are connected at the same time, the assembly becomes more convenient.
