Definitions

  • LED E27 series externally have an unaesthetic appearance, bulky, dimly shine (on average - 300 ... 500 lm) and due to the fact that there is no possibility and there is nowhere to transfer heat from diodes.
  • diodes stand on a large mass of metal, which accumulates heat in itself, but it is very badly dumped into space and as a drawback (and consequence) - all such lamps shine sectorly, due to the huge metal radiator occupying the lamp substrate .
  • the diode is not directly standing on the tube, the light source is not a point source, a huge amount of light is lost (reflected from the protective bulb back to this hexagon).
  • the design is very bulky and heavy, a lot of metal inside the emitter, where it is completely useless.
  • the radiator in this circuit stands below and implements the classic LED lamp circuit.
  • the closest analogue is (patent U 101270U) an LED lamp containing a bulb, a base for insertion into a cartridge, LEDs connected via a microcircuit to the contacts of the base, a radiator for transferring heat from the LEDs, characterized in that the LEDs are mounted on a heat pipe, which made with a base and a hollow leg-coolant, and around the lamp bulb and under it there are elements of a radiator connected to the base of the heat pipe, and inside the cavity of the heat pipe there is a heat carrier operating in the boiling phase, and the power contacts to the LEDs are drawn through
  • the lamp is equipped with a cone of mirror material located at the base of the heat pipe with the function of reflecting rays incident on the upper part of the base of the heat pipe.
  • the technical result of this solution is a compact light emitter that does not create light loss and illuminates at angles of 360x270x270 degrees, in which the cooling radiator is able to significantly increase its area without significantly increasing the size of the lamp.
  • the technical result of the claimed solution is a device that provides a colder state of the LEDs, and accordingly their luminosity (brighter) and service life are increased.
  • the claimed technical result is achieved due to the fact that the LED lamp containing the bulb, a base for insertion into the cartridge, LEDs connected via a microcircuit to the contacts of the base, a radiator for transferring heat from the LEDs, and the LEDs are mounted on a heat pipe, which is made with a base and a hollow with a heat carrier, and around and under the lamp bulb there are elements of a radiator connected to the base of the heat pipe, and inside the cavity of the heat pipe there is a heat carrier operating in the boiling phase I, and the contacts on the power LEDs made by conductive paths or wires on the surface of the heat pipe, characterized in that the LEDs

  • the lamp consists of the following elements (see Figure 1):
  • the protective flask (1) is made with a light-emitting phosphor applied from the inside (the light-emitting phosphor is not shown in the sketch), which allows the use of phosphor-free LEDs emitting in the blue spectrum in the lamp design.
  • This modernization will remove from the LEDs a part of the heat load generated in the diodes due to the internal reflection of light inside the phosphor layer in the LED. This improvement will make the lamp colder, and

  • Material (4) encloses the heat pipe, and provides tight thermal contact for heat transfer to the heat pipe.
  • Reflective cone (6) serves to minimize the loss of light entering the base of the base. It can be made of a material that reflects light well, and throws spurious rays in the right direction, making them useful.
  • the combined radiator (7) is connected to the heat pipe (5) by means of an intermediate heat-conducting material (9). This allows you to transfer heat from the heat pipe (5) to various sections of the radiator, which due to this can be spaced in space.
  • the piezoelectric element (11) creates high-frequency mechanical vibrations of the fan (8). These vibrations create the movement of air inside the radiator, thereby increasing the efficiency of heat removal.

Abstract

L'invention concerne des lampes à diodes lumineuses. Le résultat de cette invention est un dispositif assurant un état plus froid des diodes lumineuses et, partant, leur émissivité (intensité lumineuse) plus élevée ainsi qu'une durée de vie plus importante. Selon l'invention, la lampe à diodes lumineuses comprend un bulbe, un culot destiné à être inséré dans une douille, des diodes lumineuses branchées via un CI sur les contacts du culot, un radiateur de transmission de chaleur depuis les diodes lumineuses; les diodes lumineuses sont montées sur un tube thermique qui est réalisé avec une base et un pied creux utilisant le caloporteur; autour du bulbe de la lampe et en dessous de celle-ci on a monté des éléments de radiateur connectés à une base du tube thermique. A l'intérieur de la cavité on a placé un caloporteur fonctionnant en phase d'ébullition, et les contacts d'alimentation électrique vers les diodes lumineuses passant par les tracés d'alimentation électrique ou les fils qui suivent la surface du tube thermique qui se distinguent en ce que les diodes lumineuses sont placées sur une base qui est reliée à un tube thermique via un matériau conduisant la chaleur et qu'à l'intérieur du radiateur on a disposé un élément de soufflage de type éventail qui est branché sur un piézoélément réalisé de manière à permettre des oscillations haute fréquence de l'éventail.
