Abstract

PURPOSE: Conventional signal lamps are hard to recognize a signal in the daytime because of sunlight. And signal lamps consumed much electrical energy because of using an electrical bulb. CONSTITUTION: A signal lamp is modified so as to provide more recognizable traffic signal and less power equipment by using a reflective rotator inside the signal lamp. A rotating traffic signal lamp is composed of partially plated main body reflecting light, light-emitting diode embedded in main body, a rotator, a motor rotating the rotator and a worm gear transmitting the motor torque to the rotator. Electric power is used only to rotate the rotator in the daylight, so the efficiency is raised. And the more sunlight is, the more recognizable signal is. It prevent accidents from misconceive signal

Description

Turn signal light {TURN SIGNAL}

The present invention relates to a traffic light for traffic control, generally referred to as a traffic light is red. yellow. Blue traffic lights, U-TURN and left turn and variable lane traffic lights.

Since these traffic lights are used to turn on lights using electricity, there is no big inconvenience in moving according to the traffic lights at night, but if you are uncomfortable, you can mix with the flashing lights in the city center and travel to other cities. I had to go while watching where the traffic light was.

However, the traffic lights can be made large, but the current size of the lights used in the country is so huge that the situation is hard to overstate.

What about the current traffic lights during the day?

At night, no one could see the traffic lights, and even daytime drivers who had good vision because of the sun's rays might have been able to see which ones were lit.

Indeed, drivers with poor eyesight will have more difficulty.

However, it is not possible to turn on the lights brighter with higher power.

Thus, as a countermeasure, the black lampshade was put on for shading, but it is the same as the current traffic light.

The present invention has been made in view of this point, and it is an object of the present invention to deliver a reliable signal intention with very little power, and to operate the signal system even without power during the day by an additional device. Is as follows.

1 is a front perspective view of the present invention, the lower end (1-a) of the main body 1 is plated like a reflector of a flashlight to collect the light of the front and send it to the reflecting plate (3) around the light emitting for forced reflection LED 10 protrudes and accumulates as a certain number.

In the upper part, the CDS (11) whose resistance is changed by light is projected, and the central part is one of a specific color (red, yellow, blue, in the present description) attached to the rotating body (3). A plurality of light emitting LEDs 10 are attached, protruded, and stacked on the reflecting plate 3 of.

In the upper part, the CDS 11 whose resistance is changed by light is projected and accumulated, and in the center part, it is assumed that the specific color is attached to the rotating body 3, which is another body (in this description, one of red, yellow, and blue). A plurality of light emitting LEDs 10 are attached to and projected from the reflecting plate 3 of.

2 is a representative view of the present invention, the upper part of the present invention by cutting a certain portion of the drive motor (5), the worm screw (6) and the worm gear (7) power connection board (8) not shown in 1 degree and control thereof The software 11 and the wire wiring are shown and these components are configured as shown in the drawings. The operation thereof will be described in detail with reference to the drawings.

In the present invention thus made, for example, as shown in FIG. 2, it is assumed that the reflector 3 attached to the rotor 2 in the main body 1 is currently red.

Typical traffic lights are red, then blue, yellow, and then red again. The time of this signal change can be input to the software 4 arbitrarily. After the input time, the CPU of the software 4 drives the motor 5 through pin 9 of the chip.

Then, the worm screw 6 at the end of the motor 5 rotates, and the worm gear 7 engaged therewith rotates, thereby rotating the entire rotating body 2.

The reason why the drive gear is adopted in the present invention as the worm gear is that, unlike the other gears, the worm gear does not move the driven gear unless the drive gear rotates due to its characteristics, so that the color of the traffic light is not changed by the strong wind.

As the rotor 2 rotates, the connection terminals 9 connected to the power supply connecting plate 8 are separated from each other, and then come into contact with the connecting terminals of the reflecting plates of different colors.

Accordingly, the CPU of the software 4 detects a voltage change according to the resistivity of the LED 10 according to the contact between the power supply connecting plate 8 and the connection terminal 9, and immediately Stop the drive.

By this action, the rotating body 2 of the traffic light is rotated and the signal indication is changed according to the color change of the reflecting plate 3 accordingly.

Since the drive motor 5 for rotating the rotor 2 can be operated in a very small size, the rotor 2 can be rotated for a short time when the signal is changed, so that the signal can be changed and continued with very little power.

In addition, during the day, if the solar electrons are attached depending on the economical efficiency, the driving motor 5 can be sufficiently driven so that the signal can be changed without consuming power at all.

Since this solar cell is a product sold in the existing market, it can be easily added and applied to software along with a voltage conversion relay, which is an electronic component, and thus is excluded from the electronic circuit diagram of the present invention.

When it gets dark, the resistance value of the CDS 11, which is an electronic component whose resistance value changes depending on the amount of light, changes.

The change of the resistance value of the CDS 11 is input to the input terminal of the op amp, and the op amp is converted into a voltage change comparable to the central processing unit (CPU). Is input to the pin.

In this case, if the value of CDS (11) is larger than the value already input in the CPU, if pin # 15 of the CPU is set to HIGH and PHOTO DIAC 1 is turned on, TRIAC 1 is turned on and AC220V is connected to both terminals. Is applied and power of about 5V is applied to both terminals of LED.

This DC5V supply is weak and is applied directly across TR through pin 10.

The applied AC220V power supply and the DC power supply for LEDs about 5V have different uses, so the use of DC 5V power supply for LEDs will be described first.

Since the resistance of the CDS 11 is greater than the value input to the CPU, it means that the blade is dark, so that the LED 10 is turned on to force the reflection of the reflector 3. When the day is dark, all vehicles or buildings are turned on, so these lights can be directly reflected by the reflector 3, and by reflecting the reflector 3 through the reflector 1-a plated on the main body 1, There is no need to reflect, but it is configured for use as needed.

Then, the LED 10 of the rotating body 2 emits light when it is coupled with the connection terminal 8 after the power is applied to the power connection plate 8, and the light emission stops when it rotates and falls apart from each other.

LED 10 is attached to each reflecting plate 3 of each color attached to the rotor 2 (see FIG. 5). Are only made when they touch each other.

Even if the required power of a general high-brightness LED is 0.2W and all 20 LEDs shown in the figure emit light, a voltage of 5V may be possible, and the LED 10 may be added or deleted as necessary.

Next, the use of the AC220V power supply will be described.

As shown in FIG. 7, this low source has a light bulb 15 in the rotor 13, unlike the reflective rotor 2. The necessity of this is because it is difficult to rely only on the reflection of the lights of the vehicle in places where the weather is not good, such as frequent fog. 14) are connected to each other so that the light bulb 15 is lit when any terminal is in contact with the connecting plate (8).

Unlike the reflective rotating body (2), each signal plate is not a reflector (3), but a transparent or semi-transparent glass or thin acrylic plate of each color. When it is stuck or dark, as described above, the CDS 11 and the central processing unit (CPU) operation is automatically turned on.

For convenience, this rotating body is referred to as the bad weather rotating body 13, and its rotation is driven by the motor 5 by the central processing unit (CPU) like the reflecting rotating body (2).

Thus, the present invention, if the pedestrian crossing, the general traffic lights and warning lights, and also variable to replace the countless traffic lights such as traffic lights, the power savings will be enormous enough to be calculated and red, yellow, blue The existing traffic lights, which were independent of each other, can completely solve the inconvenience of looking back and forth to find out which lights were lit by daylight while using high power. Although it made the darker, the traffic light of the present invention is better to receive a lot of sunlight or light, so the body is made of white while the front plated for reflection on the front to make it look more beautiful and visually beautifying the city,

On the flat part of the front part, write down the name of the neighborhood where the traffic light is located to inform you of your current location (eg Garak-dong, Haeundae, etc ..) You can also have the effect of one stone and four pairs can be said to be a very good invention completely different from the existing traffic lights.
