Definitions

  • the lamps used in exterior lighting luminaries known today use light emitting elements such as incandescent, halogen, sodium or mercury vapor lamps, fluorescent tubes, etc. In addition to their relative short duration, these emitting elements have an important energy consumption. As a solution, in recent times low-energy light bulbs are appearing on the market, which although they have reduced the consumption of electric energy, they are still far from reasonable energy efficiency.
  • the present invention relates to a microled replacement lamp comprising a socket connected to a lower housing following which a heatsink is provided. More specifically, the lamp is characterized in that the heatsink has an indic semicilous shape, with a flat face perpendicular to the main base of the housing, a microled module being provided on said flat face.
  • a starter comprising a power supply and an inverter, whose mission is to transform the alternating current that comes from the network to 230 VAC to direct current at 36 VDC.
  • the replacement lamps object of the present invention microieds. More specifically, essentially the invention is based on the incorporation of microieds in the replacement lamps of existing urban luminaires, which can be used without problems in said luminaires thanks to the incorporation of a starter. Therefore, the luminaires already located in cities and towns could be used, replacing only the lamps without replacing or modifying any of the other components of the luminaire, achieving energy savings, which applied to the Spanish electricity grid will mean considerable reduction of electricity consumption and therefore a great economic saving.
  • microled replacement lamp As can be seen in Figure 1, and according to the numbering adopted therein, a microled replacement lamp has been represented which constitutes a preferred but not limiting embodiment of the invention.
  • the lamp comprises a socket (1) of the standard thread type E40, connected to a lower housing (2) from which a heat sink (3) is made of aluminum or a dissipating material of similar characteristics, which has a semi-cylindrical shape with a plurality of dissipating fins on its outer contour.
  • the heatsink (3) is oriented so that it is located perpendicularly to the major base (5) of the housing (2), which has an approximately conical shape of a curved generatrix, its minor base is connected to the socket (1). Therefore the flat face (4) of the heatsink (3) is located perpendicularly to the housing (2) and the socket (1), so that, in this way, said flat face is facing down when the lamp has been installed in the luminary.
  • Said configuration is due to the fact that a microled module (6) formed by a plurality of microleds is located on the flat face (4), so that the light beam can influence the ground.
  • the internal constitution of the lamp is as described below: from the microled module (6), two wires, positive and negative (not shown in the figure), run through the heat sink (3) and are connected directly to the cap (1). Since in order for the microleds to function properly, they must be supplied with a direct current at 36 VDC and the current coming from the mains comes in alternating current at 230 VAC, a starter (not shown) will be provided inside the housing (2 ) comprising a power supply and an inverter.

Abstract

L'invention concerne une lampe de remplacement à micro-DEL qui comprend un culot relié à une carcasse inférieure à la suite de laquelle est placé un dissipateur, ledit dissipateur présentant une forme cylindrique, avec une face plane perpendiculaire à la base principale de la carcasse, un module micro-DEL étant situé au niveau de ladite face plane et un démarreur comprenant une source d'alimentation et un inverseur étant disposé dans la face inférieure. Ainsi, il est possible de remplacer les lampes actuelles par une lampe à micro-DEL sans avoir à remplacer le reste des éléments qui font partie du luminaire.
