Abstract

Provided is a safety directional indicator to improve highway safety. Embodiments of the invention include devices for guiding a driver of a vehicle in a desired direction, typically away from highway workers, pedestrians, curbs, and opposing lanes of traffic. Specifically included is a safety directional indicator system comprising a flexible belt with a plurality of light transmitting bars disposed along the belt and having a plurality of LEDs disposed at one elongated end of each light transmitting bar and in operable communication with a control system for illuminating the LEDs in a manner to indicate a direction for traffic. Safety devices according to the invention can be stand-alone devices, devices capable of being attached to objects or structures at a highway scene, or configured to be worn on a person'"'"'s body. An object of the safety devices according to embodiments of the invention is to increase driver awareness of highway situations especially during conditions of restricted visibility.

Claims

1. A safety directional indicator system comprising:

a flexible belt;

a plurality of elongated light guides each with a first end and a second end, which light guides are disposed in parallel along the belt such that the longest side of one light guide is disposed parallel to the longest side of another light guide in the plurality and the longest sides are disposed perpendicular to the length of the flexible belt;

a plurality of LEDs wherein each LED in the plurality is disposed at the first end of each light guide, such that there is an equal number of LEDs as light guides, and such that during use light is transmitted from the LED through or along the light guide from the first end toward the second end of the light guide;

wherein the plurality of LEDs are in operable communication with a control system for illuminating the LEDs.

2. The safety directional indicator of claim 1, wherein the control system is operably configured for turning the LEDs on and off in a sequential manner.

3. The safety directional indicator of claim 1 further comprising a solar panel in operable communication with the control module for providing power to the system.

4. The safety directional indicator of claim 1 further comprising means for securing the belt to a surface.

5. The safety directional indicator of claim 4 comprising a buckle for securing the belt to a person.

6. The safety directional indicator of claim 4, wherein the means for securing the belt to a surface is disposed along the length of the belt on a side opposite where the light guides are disposed.

7. The safety directional indicator of claim 4, wherein the means for securing the belt to a surface comprises at least one of adhesive, snaps, hook and loop fasteners or staples.

12. The safety directional indicator of claim 1, wherein a viewing angle of the LEDs is between 30°

and 120°

.

13. The safety directional indicator of claim 1 further comprising a lens to focus light emitted from the LEDs into the light guides so as to minimize loss in flux.

14. The safety directional indicator of claim 1, further comprising a lens disposed between each LED and light guide to focus light emitted from the LEDs into the light guides so as to minimize loss in flux, and wherein a viewing angle of the LEDs is between 30°

and 120°

.

15. The safety directional indicator of claim 1 comprising a light guide with an internal reflection ranging from 50%-90%.

16. The safety directional indicator of claim 1 comprising a light guide with a refractive index ranging from 1.4-1.5.

8. A safety directional indicator comprising:

a flexible substrate strip;

a plurality of light guides, each light guide in the plurality with a first and second end, and each light guide disposed parallel to one another and along the length of the flexible substrate strip such that the longest side of one light guide is disposed parallel to the longest side of another light guide in the plurality and the longest sides are disposed perpendicular to the length of the flexible belt;

a plurality of LEDs wherein each LED in the plurality is disposed at the first end of a light guide;

such that there is an equal number of LEDs as light guides, and such that during use light is transmitted from the LED through or along the light guide from the first end toward the second end of the light guide; and

a control module comprising a power source in operable communication with the LEDs and operably configured to turn on and off the LEDs in a chasing pattern.

9. The safety directional indicator of claim 8 comprising means for operably connecting the device with another such device such that a continuous system is obtained and the system is operably configured to turn on and off the LEDs in a chasing pattern along the length of the system.

10. The safety directional indicator of claim 9, wherein one or more safety directional indicator devices is joined electrically and physically to the end of another such device in a manner to provide a chasing pattern of light along the length of the system.

11. A method of indicating a path for a driver or pedestrian to follow comprising:

providing a safety directional indicator comprising a flexible belt with a plurality of light guides, each light guide in the plurality with a first and second end, and each light guide disposed in parallel along the length of the belt and a plurality of LEDs each disposed at the first end of each light guide such that one LED is used for each light guide and each operably connected with a control module for turning the LEDs on and off sequentially, such that the longest side of one light guide is disposed parallel to the longest side of another light guide in the plurality and the longest sides are disposed perpendicular to the length of the flexible belt, and such that during use light is transmitted from the LED through or along the light guide from the first end toward the second end of the light guide;

installing the safety directional indicator on a surface of a structure such that upon illumination of the LEDs and each light guide a direction to follow is indicated by a chasing pattern of light along the length of the belt; and

providing power to the safety directional indicator.
