Abstract

A water cooled LED light 9 comprising a heat sink 1, 3, 4 (see Figure 1). A seal 2 is included and a fixing means are provided which ensure a watertight connection between the LED and the heat sink.

Description

Introduction & Background:

The current lighting systems use either large glass bulbs/lamps, also reflectors/ heat shields & large fans or big heat sinks to cool led,s & the environment they are in. This is effective in many areas for its purpose but still creating a lot of heat. This may lead to more energy being used & running costs or other problems & reliant on a lot of power.

To overcome this problem, the present invention has a way of removing the heat silent & quickly, keeping the led,s cooler & helping obtain a more stable environment they are in. This could prolonging the life of the led,s due to the impact heat has on the electrical components. This also has adjustable power options for versatility.

Statement of Invention:

The cooling of the led,s embedded or adapted to the heat sink is by means of reducing the amount of heat. This is by means of cooling is preferably by method such as direct surface contact. With maximum heat removal creating cooler electric, means electrons have less resistance. Using less power.

The led light heat sink is a module or a multi-linkable module, also small enough and light in weight, to allow easy connection or disconnection to its environment quick and safely. The design of the invention makes it easy enough to be fixed or suspended with very little effort and axis.

Optional Features:

The invention may have the option to have embedded led,s directly into it, or adapted to other led lights with less efficient cooling by the holes underneath the base plate. It also has the ability to be multi linked in a liquid cooled system or modular. The led light/heat sink also can have the option to have a reflector or lens fitted to the base by means of predrilled holes for future use.

The invention will now be described with reference to the associated drawings & pictures:

This is a complete & assembled heat sink with all parts.

This shows the base plate with holes. And with embedded leds

Figure 4:

This shows an alternative fitting of a light & additional reflector/shade & the direction of the drawing to indicate construction.

List of figures:

Figure 1. This shows the heat sink with all parts, 1,2,3,4, the seal part 2, which sits inbetween, the plates.

Figure 2. The top plate & 2 holes for fittings, and bolts part/4. Figure 3, part 1 the base plate, showing the underside showing slot “7” a power cable slot, example part 9 led,s. & process “8” fixture holes & part 4 bolt holes.

Which is all fitted together comprising of a seal in-between to seal the two surfaces together. Two holes shown in figure 2, which are situated in the top plate, these are for pipefittings to the unit, Ref to picture 6. In Figure 4 shows a shade/reflector part 5, & an adapted plate for example part 6. This also shows a machined area in the base plate part 3, cut out “10”.

Detailed Description of my invention:

A thermal reducing temperature heat sink that is water cooled, which consists of four parts to assemble,& a fabrication process. It can operate in any axis once connected to the modular system or multi-linked system. The invention has the option to be stand alone or in a multilink system. Can be adapted easily for a variety of uses & places & environments.

Picture/ illustration ref:

Picture 1:

This shows a fully built invention with all the parts as a unit apart from the bolts and the seal in place. With holes on top for fittings part shown in picture 6.

Picture 2:

This shows a side view and the top part 1 is in acrylic for bench testing and shows the bolts and any issues at time of testing,’’there were none” at present. Also note the cut out for wires slot 7.

Picture 3:

This shows the Base plate contact surface with some drilled holes for additional adaptations or under side reflector or any kind. Prior fabrication.

Picture 4:

This shows an example of led placement after fabrication directly on the surface.

Picture 5:

This shows a example of what a optional lens would be like for illustration only at present.

Picture 6:

This shows a working and tested invention with an adapted & modified part for point of extreme thermal stress testing the invention under great load. The red recyclable liquid was for illustration, which was needed for the leak test, to check the invention functioned correctly, heat conductivity & flow. This worked well as picture shows and I recorded the temps via picture and video footage.

Patent Claims:

Claims

1. A led light water cooling heat sink for led lights or light.

2. A led light water cooling heat sink according to claim 1,Where a led or led’s, are embedded in the heat sink or adapted to it, Also comprising of two main parts, Top & a Bottom.

3. A led light water cooling heat sink fixture according to claim 1 & 2 in which a top can be is attached to the fixture & a seal so it can be fixed together for cooling the led or led,s, which removes heat generated from the led,s by water cooling the led,s either mounted to it or embedded into it.

4. A led light water cooling heat sink fixture as according to all previous claims above with holes in the top plate of the base plate & threads in the base plate for fixtures to be added to & make water tight the invention.
