Abstract

The utility model provides a long-life light-emitting diode (LED) ball bulb which comprises a lamp head, a heat dissipating shell, a base seat, an LED lighting unit and a lamp cover. Two ends of the heat dissipating shell are respectively connected with the lamp head and the base seat. The LED lighting unit is arranged on the surface of the base seat. The lamp cover is arranged on one side, provided with the LED lighting unit, of the base seat. A plurality of heat dissipating fins are arranged on the outer wall of the heat dissipating shell at intervals. Heat conduction tubes are arranged among the heat dissipating fins. Compared with a common LED ball bulb, the long-life LED ball bulb has the advantages that the heat conduction tubes are arranged among the heat dissipating fins, heat on the heat dissipating fins for gathering heat can be transmitted to other heat conduction tubes to diffuse through the heat conduction tubes, the heat dissipating pins are made full use to diffuse, heat balance of the ball bulb is improved, and therefore service life of the LED lighting unit is effectively prolonged.

Description

Long-life LED bulb lamp
Technical field
The utility model relates to the LED field of illuminating lamps, refers in particular to a kind of long-life LED bulb lamp.
Background technology
Along with the maturation of LED technology, in the last few years its application of daily life also more extensively.The LED bulb lamp is exactly common a kind of.Yet because illumination needs, the power moon of existing LED is increasing, and high-power LED self can distribute amount of heat simultaneously when work, if take away even these heats be mustn't go to the life-span that can damage LED.In addition, in the LED bulb lamp, the drive circuit of LED is also a heating rich and influential family, and therefore how fast heat being taken away in the LED of little small size bulb lamp is that many enterprises make great efforts one of improved direction at present.For this reason, the LED bulb lamp adopts the structure of lamp holder, aluminum radiation shell, LED luminescence unit and lampshade more at present, realizes the LED drive circuit installed in it and the heat on the LED luminescence unit by the radiating fin of aluminum radiation shell sidewall.But due to the setting of heater members on LED drive circuit in the aluminum radiation shell and the position reason of LED luminescence unit, therefore in actual existing structure, aluminum radiation shell surface radiating temperature is normally inhomogeneous, hot-spot can occur and relative other side heat is not high, the heat build-up problem that causes thus still can affect the life-span of LED luminescence unit.Moreover the radiating fin that is limited to volume reason aluminum radiation shell surface is difficult to the more jags of design, so its area of dissipation is restricted, and the radiating fin interval that arranges of sealed spacer arranges in addition, air-flow be difficult to by, also unfavorable to dissipation of heat.
The utility model content
The purpose of this utility model is to have overcome defects, and the more rational long-life LED of a kind of radiator structure bulb lamp is provided.
The purpose of this utility model is achieved in that a kind of long-life LED bulb lamp, and it comprises lamp holder, radiation shell, pedestal, LED luminescence unit and lampshade; Described radiation shell two ends connect respectively lamp holder and pedestal, and base-plates surface is provided with the LED luminescence unit, and pedestal is covered with lampshade in LED luminescence unit one side is set; Lateral wall one circle of described radiation shell is arranged at intervals with a plurality of radiating fins, is equipped with heat pipe between described a plurality of radiating fins;
In said structure, described heat pipe is from top to bottom through between a plurality of radiating fins;
In said structure, described heat pipe is in the shape of a spiral from top to bottom through between a plurality of radiating fins;
In said structure, the sidewall of described radiating fin is provided with louvre;
In said structure, the outside of the sidewall of described louvre setting and radiating fin;
In said structure, described radiation shell is aluminum, and described heat pipe is copper.
Than common LED bulb lamp, the beneficial effects of the utility model are to have added heat pipe between radiating fin, thereby the heat on the radiating fin that heat can be concentrated by heat pipe is taken away fast to other radiating fins and is distributed, taking full advantage of all radiating fins dispels the heat, improve the thermal balance of bulb lamp, thereby effectively increased the life-span of LED luminescence unit.
Description of drawings
Below in conjunction with accompanying drawing in detail concrete structure of the present utility model is described in detail
Fig. 1 is overall structure schematic diagram of the present utility model.
1, lamp holder; 2, radiation shell; 3, pedestal; 4, lampshade; 5, heat pipe; 21, radiating fin; 22, louvre.
The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
See also Fig. 1, a kind of long-life LED of present embodiment bulb lamp, it comprises lamp holder 1, radiation shell 2, pedestal 3, LED luminescence unit and lampshade 4.Wherein, the two ends of radiation shell 2 are connected with respectively lamp holder 1 and pedestal 3, and pedestal 3 surfaces are provided with the LED luminescence unit, and pedestal 3 is covered with lampshade 4 in LED luminescence unit one side is set.
Be formed with accommodating cavity in radiation shell 2, be used for place LED drive circuit in accommodating cavity, be arranged at intervals with a plurality of radiating fins 21 at lateral wall one circle of radiation shell 2, different from tradition is also to be equipped with heat pipe 5 in this patent between a plurality of radiating fins 21.Thus, the heat of the radiating fin 21 that the heat pipe 5 of setting up can be concentrated heat on the radiation shell 2 of script heat skewness is taken away fast to other radiating fins 21 and is distributed, taking full advantage of all radiating fins 21 dispels the heat, improve the thermal balance of bulb lamp, thereby got to the purpose in the life-span that increases the LED luminescence unit.
Better, above-mentioned in, heat pipe 5 can carry out equilibrium except the heat around radiation shell 2 one circles thus from top to bottom through between a plurality of radiating fins 21, also can to its upper and lower to heat carry out balance.
Best, heat pipe 5 from top to bottom through between a plurality of radiating fins 21, can realize to greatest extent that thus heat is carried into the purpose of distributing on each radiating fin 21 fast in the shape of a spiral.
In order to strengthen area of dissipation, in this patent, also can further offer louvre 22 on the sidewall of the radiating fin 21 in said structure, and best louvre 22 arranges and the outside of the sidewall of radiating fin 21.Not only increased thus the area of dissipation of radiating fin 21 in the confined space, on a plurality of radiating fins 21, louvre 22 also can form certain fluid passage, facilitates fluid by taking away more efficiently heat.
The above is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
