The invention relates to Underwater Light (LED) of Fixed Tilt Angle 0°-80° degrees for multiple applications with elective Gyro Sensor comprising of: a fixed Inclined Outer Body with cylindrical internal configuration, under angle 0°-80° degrees, a cylindrically shaped Solid Thermally Conductive Inner Core (Head), the Peripheral Metal Layer Coatings with embedded Scaled Thermal Conductivity λ of symmetric or non symmetric coating thickness of the cylindrically shaped Solid Thermally Conductive Inner Core (Head), the LED Light Emitting Diode, the optional Gyro Sensor, the Beam Reflector, the External Lens or Diffuser, the Thermostat, the Nitrogen (N2) Charging Port, the Auxiliary Heatsink, the Rubber Gasket, the Cabling Channel, the Pressure Relief Port, the Sealing Bolt and the Front Mounting Ring.
Similar autonomous Underwater Lighting systems are bulky in order to achieve satisfactory heat dissipation and of course the mounting surface thereof, on a boat's stern for example, is approximately perpendicular towards the cruising course axis, as for example on the “transom” of speedboats. Therefore, the emitted light beam is restricted only backwards aligned with the boat's cruising axis. In addition to other use of applications such as swimming pools, decorative jet (fountains), architectural lighting or decorative waterfalls, the existing structures, in order to achieve the desired light beam emission angle, regardless of their placement, have a supplementary support extension mounted in the transverse axis (with screws). The way of such a mounting makes the whole fixture vulnerable to any external stressing (e.g. vibrations, shocks, oscillations etc.) with consequences to frequent adjustments.
The main characteristics of the invention are the cylindrically shaped Solid Thermally Conductive Inner Core (Head), on which the LED Light Emitting Diode is mounted, the Peripheral Metal Coating with embedded Scaled Thermal Conductivity λ Layers of symmetric or non symmetric metal coating thickness of the cylindrically shaped Solid Thermally Conductive Inner Core (Head), the embedded configuration for both the passage of power supply cabling and for the Nitrogen (N2) Charging as well, the optional Gyro Sensor and finally the Thermostat, for the system's overheating protection.

The invention is described in details below with reference to the attached drawings or figures in which:
The invention is described in details as follows:
1. The Underwater Light (LED) Fixed Tilt Angle 0°-80° degrees for multiple applications with optional Gyro sensor, according to the present invention has the feature of the structurally fixed Inclined Outer Body (1, 2) with cylindrical internal configuration under tilt angle from 0 up to 80° (17), which is made from corrosion-resistant (in an extremely corrosive environment such as the sea) material, indicatively, alloys of Stainless Steel type AISI 316/L 317/L or Naval Brass etc., or for example Aluminum alloys such as 7075/T6 or 2024/T4 or 6063/T6 or 6061/T6.
2. The cylindrically shaped Solid Thermally Conductive Inner Core (Head) (3), which is made of high Thermal Conductivity λ material, for example Copper, Aluminum, Naval Brass or other thermally conductive alloys depending on the application, bears 1-2 or more Layers of Peripheral Metal Coating (4, 5) with embedded Scaled Thermal Conductivity λ, of symmetric or non symmetric metal coating thickness, made of other metals with higher thermal conductivity λ coefficient, as for example copper (4) and for example, a mixture of high silver concentration (5). The specific practice of Peripheral metal coating and of course the creation of a threaded application of screw type by increasing the contact area between the inner walls of the Inclined Outer Body (1, 2) and the Solid Thermally Conductive Inner Core (Head) (3), with materials of higher thermal conductivity λ coefficient in embedded scaled arrangement and similar thickness, aims in contributing to a faster heat dissipation, which is emitted through the substrate of the light emitting diode LED (6) towards the inner walls of the Inclined Outer Body (1, 2) with cylindrical internal configuration and of course the creation of a constant thermal stress relieving “ring” draught on the outer body's walls thereof. Consequently, the center of the cylindrically shaped Solid Thermally Conductive Inner Core (Head) (3), to where the light emitting diode LED (6) is mounted, is maintained “cooler” and hence it can operate under less thermal stress.
3. The light emitting diode LED (6), which is attached on the front surface of the cylindrically shaped Solid Thermally Conductive Inner Core (Head) (3), consists for example of one or more arrays of light emitting diodes LED of visible or non visible wavelength A′ and color temperature T.
4. The thermostat (7) temporarily intervenes for protecting the operation of the unit if the temperature exceeds the predetermined by the construction limit.
5. The optional Gyro Sensor (8) activates the emission of distress signal flashes (SOS) under the each time international codification system for floating means, as long as it is about a choice of this application on floating means (e.g. yacht etc).
6. The Nitrogen (N2) Charging Port (9) ensures the maintenance thereof inside the sealed front chamber, thereby avoiding the creation of corrosion and vapor inside the Lighting Fixture (1, 2).
7. The Auxiliary Heatsink (19, 20) relates to the supplementary cooling function of the cylindrically shaped Solid Thermally Conductive Inner Core (Head).
8. The Rubber Gasket (18) ensures proofing tightness of the device and prevents water penetration.
9. The Beam Reflector (10) relates to the optional arrangement of the visual part for beam convergence or dispersion with structurally predetermined angle.
10. The Front Mounting Ring (11) is the part that gives mechanical strength and clamping strength to the existing sealing units.
11. The External Lens or Diffuser (12) is selected depending on the use of the application, being a Plano-Convex or Flat Crystal.
12. The Pressure Relief Port (13) as well as the Sealing Bolt (14) relate to the joint ensuring of both the tightness of the anterior part and the intake-conservation of nitrogen (N2) gas.
13. The cables for supply of power to the Light Emitting Diode LED (6) pass through the watertight Cabling Channel (15).
14. The mounting bolts (16) support the Light Emitting Diode LED (6) on the surface of the Solid Thermally Conductive Cylindrically Shaped Inner Core (Head) (3).
