Description



Aluminum heat sink, for multiform mounting, of

high power

Technical Sector 5
The present invention relates to an aluminum heat sink having a structure suitable for regulating the intensity of the light emitted from a
LED
and compose different architectures.

State of the Art 10
As is known, lighting based on light emitting diodes is increasingly widespread, since its use allows greater efficiency in lighting, a longer life than that of incandescent bulbs or lamps or any other type and a lower consumption Thus, such advantages are also applicable to public and commercial lighting, where saving is quite considerable, in addition to other sectors.
The junction point temperature is essential when determining the light efficiency of an LED. In order for the LED lamp to work properly and its maximum life is possible it is essential to efficiently evacuate the heat that accumulates on the chip. The excess temperature 20 can significantly reduce the life of an LED luminaire and can also affect the quality of the emitted light (color, intensity, etc.).
It must be taken into account that excess heat degrades the phosphorus and reduces the life of the lamp, reduces the ambient temperature range at which it can operate, influences the operation of the driver, alters the colors 25 and, consequently, Reduce the intensity of light.
However, it is noticeable that the majority of LED lighting systems for lighting, do not adapt to existing conventional lamps and lanterns and the replacement of such conventional lamps with lamps with LED-based lighting, is an expense very high and therefore almost unassuming.
On the other hand we can see that the lamps with LED lighting that are manufactured are not designed to offer in itself a high mechanical resistance to shocks, the action of water, etc., nor do they admit to altering the design of a set or luminaire to adapt it to new realities, such as in the case of street lighting, which requires a
total change of the whole, with the cost that this implies, not taking into account that said street lighting, as part of the street furniture, is subject to possible modifications imposed by the maintenance, conservation and remodeling of the roads and other equipment such as park or landscaped areas, which means correcting or modifying the original values of certain elements, such as lighting, which must contemplate substantial changes in values such as the height of the spotlight, its location, the proximity or not to a wall , which is illuminated on steely or on grass, brightness that gives off at certain angles, etc., to adjust to the efficiency that is required. 10
It is also observed that the current heatsinks, based on standard external measures, do not offer the possibility of playing with the advantage of placing the diode and the optics inside the sink in order to achieve a more or more lighting radius. less concentrated, as appropriate. fifteen
Finally, it should be noted that the current heatsinks, diode holders and their corresponding electronics do not, per se, allow installation under water since they require internal mounting in some other formation or housing, (individual or as a whole), to preserve and protect.
The object of the present invention is, therefore, to bring to the market a new 20 aluminum heat sink unit, based on LEDs, which adapts to conventional lighting lamps (public, shops, etc.), thus allowing replacement their lighting systems by a system based on LEDs, favoring economic savings and improving the effectiveness of lighting without having to make large investments. 25
The heatsink proposed in this invention allows both the use of a single unit and an unlimited combination thereof; offer an easy and versatile mounting system; affect it with a degree of almost absolute tightness that makes it suitable for the most adverse weather conditions and even for immersion; achieve the highest degree of mechanical resistance; easy replacement of it and even the use or replacement of any of its elements; expand or decrease lighting radios at convenience; play with the different heights in which we can place these heatsinks with respect to a given plane and thus influence effects such as brightness, etc. 35
Therefore it is an open system in configuration and light flow.

Description of the drawings
To complement the description that is being made and in order to facilitate the understanding of the characteristics of the invention, a set of drawings is attached to the present specification in which, for illustrative and non-limiting purposes, the following has been represented:

DETAILED DESCRIPTION OF THE INVENTION
In view of the figures and in accordance with the numbering adopted, an example of a preferred embodiment of the invention can be seen comprising the parts and elements described below.
Thus, as shown in Figures 1 and 2, the heatsink comprises a machined cylindrical part in which a plurality of fins or grooves (1) are visible on the outside, while on the inside, by partially emptying from each one of its ends, two cameras (2, 3) are clearly visible limited by a common bottom (4) whose position is variable, which allows both the optics (7) and the diode to enter with respect to the edge and projection of the luminous flux is of smaller opening than the projection emitted by another one where the bottom and the optics get closer to this edge.
The common bottom (4) has two holes (5) that connects both chambers (2, 3) where the two pins that the diode carries to join are inserted,
by welding, this to the electronic board that fits on the other side of the common bottom (3). Once the connection is made, the chamber (3) where the plate is housed is sealed and sealed, leaving the ends of the plate power cable to air.
In the same way, it proceeds at the other end, where the chamber (2) of the diode 5 is sealed by the adjustment of the optics (7), by means of gluing, in the recess made in the internal perimeter for its fixation.
Figure 3 shows how the external configuration of the heatsink allows different assembly architectures, where the only requirement for the elements (6) that form it is to have space between the fins or grooves 10 (1), so they can be laminar, metal cords, or any other.
Likewise, it is noted that, within its essentiality, the invention may be carried out in other embodiments that differ in detail from that indicated by way of example, and to which it will also achieve the protection that is sought as long as it does not alter, change or modify its 15 fundamental principle.
