Description

Safety display device using light emitting device {Display Apparatus of Safety using Light Emited Diode}

The present invention provides a light emitting device that can prevent traffic accidents by guiding the contents, sections, or construction periods of road construction, etc. for emergency measures until the completion of the electric drawing construction in mountain areas where electric drawing is difficult or where emergency recovery is required. It relates to a safety display device using.

Conventional safety signs are made by simply writing letters using paint on cardboard, etc. When the industrial site is not easy to observe nature for various reasons such as being located in a dark or high place, the original purpose is not achieved. There was a lot.

The present invention was devised to solve the above-mentioned drawbacks, and a clock generator for generating a single pulse and a square wave with a power supply unit 10 and a toggle switch 25 using a zener diode 11 in series constant voltage circuit ( 21 and an LED flasher connected to the NAND gate 24 between an output of the JK flip-flop 22 which is inverted each time a clock is generated in the clock generator and an output of the RS flip-flop 23 coupled to the NAND gate ( 20) and the safety sign board (C) which displays the letters with the light emitting diodes (31), and the road construction for emergency measures until the electric drawing work is completed in the mountain area where the electric drawing is difficult or where emergency recovery is required. The purpose of the present invention is to provide a safety display device using a light emitting device that can prevent traffic accidents by guiding the contents, sections, or construction periods.

If described in detail in connection with the accompanying drawings the configuration and the operation of the embodiment of the present invention to achieve the object as described above and to perform the task for removing the conventional drawbacks.

Figure 1 is a block diagram of the subject innovation, Figure 2 is a circuit diagram of the power supply unit for supplying a static power source, Figure 3 is an LED blinking circuit diagram, Figure 4 shows an embodiment of the subject innovation,

The present invention provides a power supply section 10, which is a series constant voltage circuit using a zener diode 11, an LED blinker 20 for lighting a light emitting diode at regular time intervals, and a safety sign board formed of letters using various light emitting diodes. It characterized by consisting of (30).

The power supply unit 10 is a series constant voltage circuit using a 5V zener diode 11 for generating a reference voltage connected to a 9V battery and stably supplies VCC, and the LED blinker 20 is a toggle switch ( 25) of the clock generator 21 for generating a single pulse and a square wave, and the output of the JK flip-flop 22, which is inverted each time a clock is generated in the clock generator, and the RS flip-flop 23 coupled to the NAND gate. The output is connected to the NAND gate 24, and the safety sign plate C displays letters by arranging several light emitting diodes 31 at regular intervals.

According to the present invention, the LED is turned on whenever the output of the NAND gate is '0', and since the output of the JK flip-flop is inverted by the operation of the toggle switch, the LED is alternately turned on.

Therefore, the present invention constructed and functioning as described above guides the contents, sections, or construction periods of road construction, etc. for emergency measures until the completion of the electric drawing work in the mountainous areas where the electric drawing is difficult or where emergency recovery is required. By doing so, traffic accidents can be prevented.

The present invention is not limited to the above-described specific preferred embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

The light emitting device according to the present invention comprises a power supply unit 10 which is a constant voltage circuit as described above, an LED flashing unit 20 for lighting a light emitting diode at a predetermined time interval, and a safety sign board 30 formed of letters with various light emitting diodes. The safety display device using the device is a very useful design to achieve the purpose of preventing disasters and enlightening by raising awareness about safety by guiding the contents, sections, or construction periods of road construction.
