Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an LED display device, and more particularly to a configuration for shielding light from a plurality of LEDs that display a control state of a control board of an electric device so as not to leak from each other.
[0002]
[Prior art]
As shown in FIG. 5, the conventional LED display device includes a control board 6 for controlling the electric device in the electrical component box 5 disposed in the vicinity of the rear surface of the front panel of the electric device. The LED 7 is stored in a substantially right angle with respect to the front panel so as not to take a space in the direction, and is connected by the control board 6 and the wire harness 20 to display the control state of the control board 6 and the light of the LED 7. The sub-control board 21 mounted with the light-shielding cover 8 that prevents the LED 7 from leaking into the adjacent LED 7 is housed substantially parallel to the front panel.

[Problems to be solved by the invention]
However, in the above configuration, the control board is divided into an original control board on which the control circuit is mounted and a sub control board for displaying only the control state, and a wire harness for connecting the sub control board and the control board is provided. There was a problem that it was necessary and costly.
In view of the above problems, an object of the present invention is to provide an inexpensive LED display device with a small number of components.
[0004]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides a control board having a plurality of LEDs in the vicinity of the back surface of a front panel of an electric device, and the plurality of LEDs are individually visible from the display window of the front panel. In an LED display device having a shading cover as shown in FIG.
The control board is arranged at a substantially right angle to the front panel, and the plurality of LEDs are arranged in a row in the vicinity of the front edge of the control board and directly attached to the control board, one on the control board behind the plurality of LEDs. While forming the above locking holes,
The shading cover covers the back of the plurality of LEDs, has a locking claw that locks the locking hole at one end, and a back cover that has a thin portion at the other end, and the back cover and the upper portion through the thin portion. A central cover part that connects the rear and covers the upper and side surfaces of each of the LEDs and between the LEDs with an integral wall surface, a light-shielding cylinder part that protrudes forward from the central cover part and has an open front end, and the light-shielding cylinder part And an L-shaped holding part that protrudes in an L shape from the lower surface of the control board and holds the front edge of the control board.
[0005]
Further, the light shielding cover is integrally formed of a flexible synthetic resin material such as polypropylene.

DETAILED DESCRIPTION OF THE INVENTION
The embodiment of the present invention will be described with reference to the embodiment of the present invention shown in FIGS.
As shown in the overall configuration diagram of FIG. 1, 1 is an electrical device such as an indoor unit of an air conditioner, 2 is a front panel that covers the front surface of the electrical device 1, and 3 is a plurality of displays provided on the front panel 2. A display unit 5 having a window 4 is an electrical component box in which a control board 6 for controlling the electric device 1 is accommodated at a substantially right angle with respect to the front panel 2 so as not to take a space in the width direction of the front panel 2. is there.
As shown in the exploded perspective view of FIG. 2, reference numeral 7 denotes a plurality of LEDs for displaying the control state of the control board 6, and the LEDs 7 are directly attached to the control board 6 together with other electronic components.
As shown in an exploded perspective view of the main part of FIG. 3 and a cross-sectional view of the main part of FIG. 4, 8 is a flexible composite such as PP (polypropylene) that shields the light from the plurality of LEDs 7 from leaking next to each other so as not to be mistaken. The light shielding cover 8 is integrally formed of a resin, and the light shielding cover 8 covers the back surface of the plurality of LEDs 7 and is locked at one end to a locking hole 9 formed in the control board 6 behind the LEDs 7. The locking claw 10, a back cover 12 having a thin portion 11 at the other end, and the back cover 12 and the upper rear portion are connected via the thin portion 11, and the upper and side surfaces of the plurality of LEDs 7 and the LEDs are integrated. A central cover portion 13 covered with a typical wall surface, a light shielding cylinder portion 14 projecting forward from the central cover portion 13 and having a front end opened, and projecting in an L-shape from the lower surface of the light shielding cylinder portion 14 in front of the control board 6 And an L-shaped holding portion 15 that holds the edge. .
[0007]
Next, the operation and effect of the above configuration will be described.
First, as shown in FIG. 4A, the locking claw 10 of the back cover 12 is locked in the locking hole 9, and then, as shown in FIG. The light shielding cover 8 is attached to the control board 6 so as to cover the LED 7 by locking the L-shaped holding portion 15 to the front edge of the control board 6 while being bent at 11. By directly attaching the LED 7 to the control board 6, it is not necessary to provide a display-dedicated board and a wire harness connected thereto, and an inexpensive configuration can be obtained.
Further, since the light shielding cover 8 is integrally formed, only one component is required. Further, the light shielding cover 8 can be easily attached to the control board 6 by the locking hole 9 and the L-shaped holding portion 15. An inexpensive configuration can be obtained.
[0008]
【The invention's effect】
As described above, according to the present invention, an inexpensive LED display device having a small number of parts and a low cost is obtained.
