Definitions
- the present invention relates to a LED lighting device, more particularly a lamp holder for light sources with replaceable LEDs integral with a heat sink.
- Document WO 2010/146509 A1 discloses a connector to connect a component to a heat sink, comprising a support for a light source, a LED light source, a connector for feeding said light source, wherein the heat sink has means for fixing it to a lamp, where the connection is achieved by a bajonet joint and the heat sink is not a load bearing structure of the device, and replacement of the LED light source requires disassembly of the printed circuit board.
- the LED lamp holder according to the present invention is designed in order to avoid the above mentioned drawbacks of adaptability and heat generation, providing for a lamp holder that in a preferred embodiment is made integral with the heat sink, which in turn may be interfaced on one hand with the light source and on the other hand with any lamp.
- the main object of the present invention is to provide a lamp holder for LED light sources, that may be used as alternative or substitution for the traditional lamp holders, either for new or existing lamps.
- an object of the present invention is to provide a lamp holder for LED light sources, wherein heat dissipation is efficiently achieved by a passive device.
- the heat sink 10 is a cylindrical body of extruded aluminum, so as to obtain a set of winglets 12 radially extending outwards from its central cavity or through hole 14. At positions axially symmetrical to the longitudinal axis of said cavity, three winglets 12a have a greater thickness than the remaining winglets 12 and a preferably threaded bore 12b, in which a first end 72 of said brass tubes 70 is screwed.
- the through hole 14 too is internally threaded at both ends 14a and 14b.
- the heat sink 10 approximately at its median portion has a flange 18 with the function of abutment for attachment elements to a lamp (not shown) such as collar 60.
- the flange divides the outer surface of the heat sink in a first portion 10a (facing the support 20 and the corresponding light source) and a second portion 10b.
- Portion 10a is advantageously threaded to allow connection with the collar 60 (or similar connection element with a lamp body) which is internally threaded.
- support 20 comprising a disc 22, on whose upper surface 22a there is a seat into which the light source or board SMD-LED 30 may be slidingly inserted; in said seat electric contacts are also fixed, made of C-bent metal plates: the upper side of the C-bend of each plate is in contact with a terminal of the SMD board, while the lower side is connected to a pin which, through suitable holes made in the seat, passes through the disc 22 body and comes out from the lower surface 22b of the disc. From said lower circular surface 22b of disc 20, two approximately circular surfaces 24 are extended and externally threaded for engaging the thread 14a of the heat sink 10.
- More particularly surfaces 24 are so dimensioned as to receive and hold by friction a connector 50, into which the above mentioned electric pins are inserted. Finally, from connector 50 a pair of feeding wires 52 extended to traverse the cavity 14 of the heat sink 10 and available for the connection of an external power source (not shown). Therefore in this way the electric circuit of the lamp holder is defined, allowing to feed the LED light source just like a traditional lamp holder for incandescent or bulb light sources.
- a lens 40 consists of a ring 42 and a member 44 that may be transparent, opaque or anyway treated for a correct diffusion of the light emitted by the LED.
- Ring 42 is made integral with protrusions 46 diametrically opposed and so shaped as to snap engage the above described support disc 20.
- said lamp holder 100 fully achieves the above indicated objects of adaptability to existing lamps as well as to lamps of novel conception, without needing any modification thereof. Even the problem of overheating the lamp holder is solved by adopting the passive heat sink 10 with great thermal exchange surface, thus avoiding adoption of noisy ventilation systems involving additional energy consumption. Besides adaptability one can see also a considerable ease of replacement of the light source, by removing the lens and simply sliding the board out from the support seat, said replacement being required not only in the event of failure but also in case of another LED with different lighting characteristics.
