1. Field of Invention
This invention relates generally to the field of marine navigational and regulatory markers and more specifically to a regulatory buoy with the ability to illuminate and display the contents of its message at night. Regulatory and marker buoys are used to inform boaters of important information. Much like a road sign conveys important information on our highways; regulatory buoys provide important information to boaters on our waterways. Some common messages may read “Danger Shallow Rocks”, “Slow No Wake”, “Swim Area”, or “Marina Entrance”; however, there are hundreds of messages that can be displayed. These messages are also accompanied by different symbols which provide detailed and important information to boaters. Buoys provide boaters information during daylight, however, at night buoys can be extremely difficult to see and safety hazards are not apparent. At night boaters often collide with buoys leading to extensive damage to both buoy and boat. Without proper illumination of buoys, boaters without headlight systems will not be able to read the important message displayed on the buoy and as a result, will not be informed of the important information they need to know in order to safely navigate the waterways.
2. Prior Art
Thereafter, inventors created various methods for making buoys visible at night such as attaching reflective materials, or using storage type fluorescent materials, and furthermore, by adding various forms of lights to buoys.
Buoys that rely on reflective materials to be visible at night have several problems. Reflective materials are often separated from the buoy during boat collisions, water abrasion, element exposure, and wearing off over time. All of these factors reduce the reflective materials visibility. Reflective materials require an initial light source to shine toward the reflective material in order for the reflective material to reflect light back towards the viewer. This is problematic as many nighttime vessels do not use headlights. Buoys and boats move with wave action, which means the angle at which light is directed and reflected may not result in visibility at all times.
Lighting elements and or beacons are typically affixed to the tops of buoys and therefore are easily damaged or rendered less effective from bird droppings, debris, abrasion, and collision. Signaling lights or beacons are also added to the tops of buoys which blink in accordance with maritime flash codes, however, boaters not familiar with maritime flash codes may not understand the important message the buoy is intended to convey.
U.S. Pat. No. 4,501,564 to Cairone (1985) is an illuminating foam float that utilizes fluorescent or phosphorescent or luminescent pigments to emit light at night. Phosphorescent pigments are problematic for using on buoys as they are very dim and do not provide visibility at far distances or for prolonged periods of time. Phosphorescent pigments dim rapidly shortly after dark and do not provide the full lighting effect through the duration of the night. If there is an overcast or cloudy day the phosphorescent pigments will not absorb enough sunlight and will result in short illumination times. In addition portions of the buoy which are face down in the water will not absorb sunlight during the day and thus as the buoy rotates at night, it may expose an area that does not illuminate. In general, fluorescent materials at maximum have low luminance and short light emission times. For this reason, phosphorescent or luminescent materials are not typically bright enough or long lasting enough to provide effective means for lighting buoys.
U.S. Pat. No. 4,809,458 to Tanikuro & Nagamatsu (1989) is a self-luminous buoy that does not provide illumination to the lower half of the buoy and or hemisphere. Furthermore the general lighting direction is upward and it may be difficult for boaters at distances to view the buoy from the side.
U.S. Pat. No. 5,362,267 to Forrest (1994) is a solar powered buoy, however, is designed as a signaling buoy and emits a signaling light. Signaling light is generated by flashing the light source on and off at set intervals and patterns. This design incorporates a translucent lens body which makes the buoy more difficult to see as it will visually blend in with the water or background. Furthermore, this buoy only conveys light flashing or signaling messages. Persons or boaters not familiar with maritime flash codes would not understand the meaning of the buoys message.
The primary objective of the invention is to provide a highly visible buoy which conveys a visible and legible message to boaters at both day and night.
Another object of the invention is to provide a lighted buoy that provides a silhouette or lighted view of the buoys message and symbol content so that it is easily readable by nighttime boaters.
Another object of the invention is to provide a lighted buoy that boaters can easily identify at night to prevent vessel-buoy collisions.
Another object of the invention is to provide a lighted buoy with reflective material in which the buoy can be visible at night under reflected light even if the light source is rendered off.
Another object of the invention is to provide a lighted buoy where attached messages and symbols placed on the buoy body create a silhouette or lighted view of the message and symbol content.
Another object of the invention is to provide an easily serviceable self contained solar lighting unit which provides illumination to the buoy.
Another object of the invention is to provide an easily serviceable self contained solar lighting unit which does not require removing the buoy from the water for service such as battery replacement.
Another object of the invention is to provide a self contained solar lighting unit which is recessed from the buoy body so that it is protected from abrasion and collision with watercraft.
Yet another object of the invention is to provide a buoy constructed of rotational molded Poly Ethylene material which is translucent enough for illuminating at night yet opaque enough to remain highly visible during the day.
