The utility model content

The purpose of this utility model is to provide a kind of lamp cooling structure, can help the LED light fixture to dispel the heat rapidly, improves the service life of LED light fixture.

According to above-mentioned and other purpose, the utility model provides a kind of lamp cooling structure, this light fixture mainly is assembly one a LED tabula rasa in a lampshade and an euphotic cover, it is characterized in that: this lampshade outer surface forms the radiating fin that a plurality of intervals are provided with, and this LED tabula rasa is by being located at the inner surface of this lampshade.

According to above-mentioned lamp cooling structure of the present utility model, the radiating fin that a plurality of intervals of its moulding on lampshade are provided with, and with this LED tabula rasa by being located at the inner surface of this lampshade, the contact conduction that utilizes the LED tabula rasa to contact with lampshade physics, in real time with the luminous thermal energy conduction that sheds of LED tabula rasa to the lower lampshade of temperature, by the ventilation and heat of radiating fin in the lampshade outside, to get rid of heat, and the sustainable lower radiating fin of temperature that is passed to of the heat that makes the LED tabula rasa, promote the rate of heat dispation of light fixture by this, prolong the service life of the light fixture that sets the LED tabula rasa.

For achieving the above object, the technical scheme that the utility model adopted is: a kind of lamp cooling structure, this light fixture mainly are assembly one LED tabula rasas in a lampshade and an euphotic cover, it is characterized in that:

This lampshade has a thermal conductive zone, the radiating fin that a plurality of intervals that should thermal conductive zone be shaped outside this lampshade are provided with; And

This LED tabula rasa be to should thermal conductive zone by being located at the inner surface of this lampshade.

Described lamp cooling structure, this LED tabula rasa comprise a radiating piece, a plurality of pedestal and a plurality of LED that is equipped on this base-plates surface, this radiating piece to heat-conducting part that should lampshade by being located at this lampshade inner surface.

Described lamp cooling structure, thermal conductive zone moulding one distribution trough of this lampshade, this LED light version is the notch outer rim that is positioned at this distribution trough, the distribution of its supply LED power supply is to be equipped in the distribution trough of lampshade.

The employing the beneficial effects of the utility model are: the utility model provides a kind of lamp cooling structure, it is the radiating fin that a plurality of intervals of moulding are provided with on lampshade, and with this LED tabula rasa by being located at the inner surface of this lampshade, the contact conduction that utilizes the LED tabula rasa to contact with lampshade physics, in real time with the luminous thermal energy conduction that sheds of LED tabula rasa to the lower lampshade of temperature, by the ventilation and heat of radiating fin in the lampshade outside, to get rid of heat, and the sustainable lower radiating fin of temperature that is passed to of the heat that makes the LED tabula rasa, promote the rate of heat dispation of light fixture by this, prolong the service life of the light fixture that sets the LED tabula rasa.

The specific embodiment

For making lamp cooling structure of the present utility model clearer and more definite, below will be described in more detail with graphic cooperation embodiment.

See also Fig. 1 to Fig. 3, the utility model lamp cooling structure comprises a lampshade 1, an euphotic cover 2 and a LED tabula rasa 3.

This lampshade 1 has a thermal conductive zone 11 and an echo area 12 around this heat-conducting part 11, and in this thermal conductive zone 11 moulding one distribution trough 13, the radiating fin 14 that a plurality of intervals that should thermal conductive zone 11 be shaped outside lampshade 1 are provided with, and to being equipped with a reflecting element 15 in echo area 12.

This euphotic cover 2 is to set with this lampshade 1, is disposed at circuit in the lampshade 1 with protection.

This LED tabula rasa 3 comprises a radiating piece 31, a plurality of pedestal 32 and a plurality of LED33 that is equipped on these pedestal 32 surfaces, this radiating piece 31 is by being located at this lampshade 1 inner surface and being positioned at the notch outer rim of distribution trough 13 to heat-conducting part 11 that should lampshade 1, the distribution of its supply LED33 power supply is equipped in the distribution trough 13 of lampshade 1, this pedestal 32 that is equipped with LED33 is another surfaces that are installed in this radiating piece 31, and the light that LED33 is radiated can be transmitted to outside the lampshade 1 by euphotic cover 2.

According to above-mentioned the utility model lamp cooling structure, when LED tabula rasa 3 electrified light emittings, can send a large amount of heat in short time, at this moment, because of the radiating piece 31 of LED tabula rasa 3 is thermal conductive zones 11 by being located at lampshade 1, be the physics contact, the heat of LED tabula rasa 3 can conduct to the radiating fin 14 of lampshade 1 by both contacts, and dissipate to lampshade 1 outside, make heat energy can not be accumulated in the light fixture, and quickening the dissipation of radiating fin 14 heats of lampshade 1 by the circulation of light fixture extraneous air, the heat of guiding lampshade 1 inside is to radiating fin 14 conduction of the lampshade 1 of low temperature, and promotes the rate of heat dispation of light fixture.

See also Fig. 4, it is another embodiment of the utility model lamp cooling structure, and itself and previous embodiment are roughly the same, and only, the thermal conductive zone 11 of its lampshade 1 does not have distribution trough and makes LED tabula rasa 3 and lampshade 1 that bigger contact area be arranged.

According to the contact conduction pattern of above-mentioned each embodiment of the utility model lamp cooling structure, the radiation conduction of more existing LED in light fixture is more efficient, make the utility model can be fast with thermal energy conduction to outside, and have good heat-conducting effect.

In sum, lamp cooling structure of the present utility model, it is the radiating fin that a plurality of intervals of moulding are provided with on lampshade, and with this LED tabula rasa by being located at the inner surface of this lampshade, the contact conduction that utilizes the LED tabula rasa to contact with lampshade physics, in real time with the luminous thermal energy conduction that sheds of LED tabula rasa to the lower lampshade of temperature, by the ventilation and heat of radiating fin in the lampshade outside, to get rid of heat, and the sustainable lower radiating fin of temperature that is passed to of the heat that makes the LED tabula rasa, promote the rate of heat dispation of light fixture by this, prolong the service life of the light fixture that sets the LED tabula rasa; So practicality of the present utility model should be unquestionable, the disclosed structure of the utility model embodiment in addition, be not seen in publication before the application, also not public use, hereat, " novelty " of the present utility model " progressive " all meets again, and the whence proposes the application of utility model patent in accordance with the law, earnestly hope and give examination and grant accurate utility model patent early, the true feeling moral just.
