Abstract

The Laser-beam perspective triangle emergency warning sign is a device that projects lasers on the road surface in the form of a perspective image in such a way that is easily seen by the approaching drivers' point of view as a standing triangle warning sign. This device is a substitute for the vehicles' triangle warning sign and eliminates its numerous problems. Technical Problem: Using a small triangle warning sign and installing it on the road (at a distance of 50 meters) to warn others of the of the car being pulled over has many problems (including low visibility, the driver having to leave the car, losing the triangle warning sign, the driver's fatigue or inability to setup the triangle warning sign, long setup time and the probability of accidents taking place in the meantime, the triangle warning sign being hit or falling down, etc.) and it is not an appropriate solution for the problem. Principles of the proposed solution: The appropriate solution is to use the newly invented device which projects laser-beams on the road surface in the form of 3D triangle warning sign images as soon as it is set up. The driving cars will see these images as totally standing solid objects (just like the advertising banners used on football fields, (figure 1)). Major applications: A substitute for the triangle warning signs, used on all vehicles. Technical highlights: Using a perspective triangle warning sign image with laser-beams.

Summary of Invention

Technical Problem

Every day, there are numerous reports of road accidents, some of which are due to the forced stopping of cars due to technical problems or break downs and the inability to warn other drivers that are passing by of what has happened, especially in the dark. This is due to lack of proper warning equipments (appropriate triangle warning sign) in cars, driver's laziness or fatigue, bad environmental conditions that keeps the driver from getting out of their car, etc.

1. out of the car (theft, wild animal attack, etc.).

2. Other cars might hit Long setup time due to the distance of where it has to be set up.

3. Difficult setup process and the probability of the triangle warning sign falling down by the wind or other factors.

4. Risks of getting the triangle warning sign.

5. Low visibility of the luminous triangle warning sign due to its small size or foggy weather.

6. The driver's inability to setup the triangle warning sign (disabled drivers).

Solution to Problem

By installing this device on vehicles, the driver of the pulled over car will not need to set up the triangle warning sign at the approximate distance of 50 meters. Instead, the laser-beams will be projected at appropriate standard distance on the road as soon as the device is turned on and the intended images or signs will be shown in 3D form such that the other driving cars will see them as standing signs from their viewpoint. Accordingly, they will be informed of the pulled over car and the driver's need (Image no. 3). Advantageous Effects of Invention

The laser-beam perspective triangle emergency warning sign is a device that projects lasers on the road surface in the form of a perspective image to warn others of the car being pulled over on the road (can be installed on all vehicles).

1. Ease of use.

2. Short installation time.

3. High visibility in all weather conditions and surfaces.

4. Usable in flasher mode to grab more attention.

5. The ability to show different signs.

6. Works without having to use the car's electrical system due to its chargeable batteries.

7. Can be separated from the place it was installed in the car and changed to another place for installation.

Brief Description of Drawings

[0003] No drawings are considered for this invention. However, Images No. l, No.2 and No.

3 could sufficiently help the case to get better understood.

Description of Embodiments

Perspective: A relative display of an image on a flat surface as it is perceived by the eyes (figure 1 presents an example of using images on a two-dimensional surface displayed on the ground, however, they are totally seen as standing from the camera's viewpoint).

Laser: Laser is the tool that emits light in the form of very narrow parallel beams with a specific wavelength. This tool is comprised of a light collector or activator material that is placed inside a light intensifier chamber. This material intensifies the light beam created by an external source of energy (figure 2 presents an example of available optical lasers in different colors. The desired images can be displayed on different surfaces by designing and placing the lens on the head of the device).

As an example (figure 3), by designing the image of the triangle warning sign in perspective on the lens of the lasers available on the market, the image of the triangle warning sign will be displayed in 3D format on the road (for the first time) and the approaching drivers will perceive it in fully standing form, which will prevent probable accidents. Major Applications: A substitute for the triangle warning signs, used on all vehicles.

Technical advantages: Using a perspective triangle warning sign image with laser-beams. Description of the plans: The main purpose of creating the new innovative collection is to create a product that can fulfill the function of the triangle warning signs without the current problems. To this end, the virtual image of the perspective triangle warning sign displayed on the road by color laser light (available in figure 2) is used instead of the physical object. Figure 1 presents an example of using perspective images. These images are in fact totally 2-dimensional, while they are seen as 3-dimensional standing objects. Plan 3 presents the system function from a high-angle view and the approaching driver's view of to the pulled over vehicle.

The perspective image of the triangle warning sign is holographic ally printed on the transparent lens of the laser head and when the device is placed in the light path, a standing image of the triangle warning sign similar to the physical object forms on the road. Figure 2 presents examples of using lenses with holograms special for laser heads in 2-dimensional format.

Industrial Applicability

[0004] A substitute for the triangle warning signs, used on all vehicles.

Claims

[Claim 1] In its main application, The Laser-beam perspective triangle emergency warning sign is a device that is installed on the vehicle that projects lasers on the road surface in the form of a perspective image in such a way that is seen by the approaching drivers' point of view as a standing triangle warning sign.

[Claim 2] Device Components, Techniques and Innovations: color laser lights (also called laser pointers) are used as the light source of the device. Special transparent lenses with perspective triangle warning sign holograms are also used (for the first time) on the laser light path in order to refract and change the laser light into the perspective image of the triangle warning sign (perspective: a relative display of the image on a flat surface as it is perceived by the eyes).

[Claim 3] The device can be separated from the body of the car because of chargeable

batteries.

[Claim 4] Other applications of the invention and its components:

Source of light: laser. - Laser refraction and creation of 3-dimensional images: in two forms, using patterned transparent lenses and/or using laser light projector with the ability to show images. Application: for example, to form 3-dimensional images of traffic signs on the roads.

[Claim 5] The size and location of projecting the triangle warning sign on the surfaces are done manually and automatically. The formed image is also designed in fixed and flasher modes.
