Abstract

(57) [Summary] [Purpose] To provide a display device that lights up a comment character to a subsequent driver and serves as a means of communication. [Structure] Light emitting diodes (6) are arranged on a substrate (10) to form several kinds of comment characters, and a comment suitable for the spot is selected and displayed in a lit state.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 This invention relates to the display of a message by a light emitting diode mounted on the rear of a vehicle.

[0002]

[Prior Art]

 In the past, there were dials on which various texts were written and light bulb type display devices that cut out the letters and let light pass through.

[0003]

[Problems to be solved by the device]

 This had the following drawbacks. (B) It was troublesome to replace the dial plates for various comments each time. (B) Due to indirect illumination, its efficiency is poor, and therefore current consumption is large. The present invention has been made to eliminate these drawbacks.

[0004]

[Means for Solving the Problems]

 Prepare the required number of display letters (6) and lighting switches (4) with light emitting diodes for comments. Further, the character display is turned on by directly passing a current through the light emitting diode (6). The present invention is a display device having the above configuration.

[0005]

[Action]

 Several types of character display can be selected by the lighting switch (4). Further, since the current is directly applied to the character display light emitting diode (6), the efficiency is 100% and the current value is several tenth of that of the light bulb.

[0006]

【Example】

 Embodiments of the present invention will be described below. (A) The light emitting diode (6) is arranged at the rear of the automobile (1), and the display device (2) displaying comment characters is attached. (B) Several types of comment characters (6-1, 6-2, 6-3, etc.) are prepared. The switches (4-1, 4-2, 4-3, etc.) corresponding thereto are also the same. (C) The comment character light emitting diode (6) is connected to the battery via the switch (4), the transistor (7) and the resistor (9). (D) A color acrylic plate (8) is placed in front of the character light emitting diode (6) so that the inside cannot be seen when it is turned off. The present invention is configured as described above, and when using it, select one of the comment characters (6-1, 6-2, 6-3, etc.) that is needed at that time, and switch it. When (4-1, 4-2, 4-3, etc.) is turned on, a current flows through the light emitting diode for comment characters (6) to emit light, so the comment characters are displayed blinking through the color acrylic plate (8). You can do it. In addition, (5) is a timer for blinking.

[0007]

[Effect of the device]

 It is a very excellent display device that can immediately send the comment character to the following driver by selecting the desired comment and turning on the switch. It is an excellent communication means between drivers.
