  • the present invention has its technical field in electricity, electronics, mechanics and optics since it provides an improvement to the lamp that works with high power LEDs, used mainly in public lighting systems.
  • LED lamps As the current technology for public lighting is known, it mainly uses sodium vapor or metal additives in its devices, which has considerably reduced the consumption of electrical energy with respect to incandescence, although it is worth mentioning that quality in the light has been lost, since this is yellow-orange and of poor quality. That is why in recent years LED lamps have been developed that emit white light and use gallium and phosphorus (high power white LED).
  • LEDs which when mounted on electronic cards can form modules, use various designs of light reflecting surfaces emitted by the LEDs, have optical systems, lenses or different types of reflectors to distribute more broadly of light, heat diffusers and temperature regulators that are also used and although they fulfill their mission they are usually too cumbersome, heavy and expensive.
  • high power LEDs have not been used, which emit a considerably greater luminous flux than traditional LEDs and the main reason is the heating of the LEDs that when reaching their junction temperature range these considerably reduce their life by an early degradation caused by high temperature. This is due to an inefficient heat dissipation and this is one of the most important innovations in my new design since it allows a greater number of LEDs and a more efficient dissipation extending the life of the LEDs in a smaller space.

  • the high power LED lamp consists of:
  • a connector (1) electrical "Standard” type Mogul E-39 which has a threaded bushing (2), which has at one of its ends a metal tip, used to make electrical contact when it is screwed into the " socket "or female connector of the luminaire and thus feed the high power LED lamp with energy from the power supply network that could be 80 to 265 volts alternating current.
  • a cable with the current (3), and a neutral cable (4) which in turn are connected to a "power source” that It is an electronic swicheo source where an electronic card acts to condition the electrical energy.
  • the other end of the electrical connector (1) has a handle (5), which is used to assemble it inside;
  • a base (6) made of plastic, that gives body to the high power LED lamp and is similar to a dome that has: first hole uri where a first hollow cylindrical connector (6a) comes out, the which has a pair of stops, close to each other, located on its outer face so that the base (6), can rotate within a positioning ring when the lamp is installed.
  • a second hole formed by the semi-cylindrical cavity located inside the base (6) has in its perimeter positioners (9), distributed radially and equidistant from each other, each equipped with a threaded bore, these have the functions of connecting with the connectors of a diffuser ring described below and at the same time serve to hold a second hollow cylindrical connector, which extends from the inside of the base (6), out of it and is intended to be a coupler that is inserted into the inside of a diffuser ring described below;
  • a positioning ring (10) is made of plastic, it has two stops next to each other, located on its inner face (10), which make contact with the external stops (6b), located in the first cylindrical connector (6a), of the base (6), when the lamp is installed.
  • the internal stops of the positioner ring make contact with the external stops of the first cylindrical connector, to allow the high power LED lamp to rotate in both directions up to 180 degrees and address once it has been installed, as the "socket" of the luminaire that has a random fixed position, so that when the lamp is installed it does not always direct its light in the desired direction due to this condition of coupling between the electrical connector (1), and the "socket" of the luminaire;
  • the diffuser ring (12) is made of aluminum and has: a polar arrangement of external "teeth” (13), and internal “teeth” (14), formed by rectangular aluminum strips used as the fins do in a condenser, dissipating the heat generated by the "power source” and the high power LEDs described below.

  • the cover (16) is a disk that fits into the recess (11) of the diffuser ring (12), serves to protect and mount on it the electronic card of Ia "power source” (15), by means of posts (18), with threaded holes, distributed radially and equidistant from each other, thus preventing the card from coming into direct contact with the back face of the cover (16 ),
  • a first pair of past holes (21) in the central area used to introduce in each of them the positive and negative comment cables, respectively from the electronic card so that they can reach the high power LEDs, with regulated and conditioned electrical energy so that they can operate; a second pair of past holes (20), a first series of past holes (33), distributed radially and equidistant from each other, in all their perimeter these Ie allow to screw it with the holes of the "boxes" (15), of the diffuser ring (12), when these are coupled; a second series of past holes (34), distributed radially and equidistant from each other, located only in
  • Said major plate (23), and the 2 small plates one on each side (23a and 23b) have on their surface past holes distributed equidistant from each other, which they form, in rectangular arrangement coincide with the centers of the card holes LED carriers (24), so they can be screwed.
  • a third rectangular plate (25) converges, which functions as a post from which a pair of plates come off perpendicularly, at approximately half of its height.
  • rectangular quarters which are each followed by a fifth rectangular plate, which itself is inclined, so that the rectangular plates fourth and fifth, respectively they form an internal angle and are similar to two branches as seen in Figure 14, which serve to give body and rigidity to the lamp but on them and in one piece are distributed heat dissipating vanes that serve to dissipate the heat generated by the LEDs and allows the lamp to use more power LEDs.
  • the main plate (23), the third rectangular plate (25), and the plate (25b) are provided with a specific Angle that distributes the light evenly in a cylindrical nature which makes a correct light distribution in the street of the high power LED lamp;

  • the polycarbonate protector (45) that fulfills the function of protecting the LEDs and giving an exact distribution of the light rays as required in public lighting, this in turn has holes to be screwed into the rectangular plate ( 23) and (24), of the diffuser platform and a rubber gasket (42) to avoid moisture leaks also used to direct the light emitted by the high power led.
  • the number of high power LEDs (30) may vary according to the needs of the users. In this example we talk about 30 being able to reach up to 50 leds.

Abstract

Cette invention concerne une lampe pour l'éclairage publique équipée de DEL haute puissance et destinée à remplacer les lampes actuelles à vapeur de sodium et additifs métalliques. Les mêmes éléments luminaires O-V15 et/ou analogues sont utilisés avec une source de puissance intégrée à douille standard qui fonctionne pendant les intempéries et qui produit plus de 5000 lumens grâce à sont dissipateur thermique efficace et aux DEL plus efficaces. La lampe décrite dans cette invention se caractérise en ce qu'elle comprend un connecteur électrique standard lui permettant d'être couplée à n'importe quel type de luminaire ou projecteur; une base à l'intérieur de laquelle un connecteur est utilisé pour permettre son raccordement à un anneau diffuseur pourvu de dents externes et internes pour dissiper la chaleur générée par une source d'énergie utilisée pour réguler et conditionner l'énergie électrique provenant du réseau; un couvercle pour fermer l'anneau diffuseur et protéger la carte électronique. La lampe à DEL haute puissance comprend une plate-forme de diffusion de chaleur pourvue de feuilles dissipatrices de chaleur en aluminium d'une seule pièce, ces feuilles sont utilisées pour dissiper la chaleur générée par les DEL haute puissance lorsque celles-ci sont activées et elles servent également pour le montage des cinq cartes de DEL avec l'angle exact et particulier de sorte que les DEL aient une distribution très similaire à celle de type I considérés comme optimale pour l'éclairage des rues et des avenues, permettant ainsi une plus grande distance entre les lampadaires. Enfin, la lampe à DEL haute puissance comprend une seule protection de polycarbonate qui lui permet de résister aux intempéries et de diffuser correctement la lumière
