Abstract
The utility model relates to a heat radiating structure used for an LED illumination device, which mainly adopts a structure that a tubular heat radiating tube is arranged above an LED heat radiating end, an air inlet is arranged at the bottom end of the heat radiating tube, and an air outlet is arranged at the top end of the heat radiating tube. By utilizing the chimney effect and the air convection suction force of the heat radiating tube, the LED high-temperature air positioned below the heat radiating tube is discharged from the air outlet at the top end after being sucked through the bottom end of the heat radiating tube. The heat temperature generated during the operation of the LED is quickly discharged so as to prolong the service life of the LED.
Description
(1) technical field:
The utility model relates to a kind of LED lighting device radiator structure, especially refers to a kind of LED of making LED illumination device acceleration heat radiation, to prolong the LED LED lighting device radiator structure in service life.The heat abstractor that belongs to lighting device.
(2) background technology:
LED is little because of volume, brightness is high and tool is economized electrically, so that the trend that day by day replaces general fluorescent-lamp tube and bulb is arranged.But during LED work, can produce the heat temperature, temperature is high can to reduce LED service life, so, knownly all can connect a heat sink (common for fin-shaped heat sink) at the LED radiating end, utilize heat sink to increase the LED area of dissipation, the high temperature that is produced when making LED work can dispel the heat rapidly.This kind LED radiating end connects the pattern that heat sink dispels the heat, and because of heat sink can dispel the heat complete because have lower temperature to lower the temperature around the heat sink, has the slow shortcoming of heat radiation.
(3) utility model content:
The purpose of this utility model is to provide a kind of LED lighting device radiator structure, makes LED quicken cooling, to prolong the service life of LED.
A kind of LED lighting device of the utility model radiator structure, its technical scheme is: a tubulose radiating tube is set above the LED radiating end, radiating tube bottom tool one air inlet, the top is provided with a gas outlet, utilize the stack effect and the cross-ventilation suction of radiating tube, the LED high temperature air that will be positioned at the radiating tube below is discharged by the gas outlet, top by the air inlet suction back of radiating tube bottom.Thereby make LED do the heat temperature acceleration discharging that the time spent produces, to prolong LED service life.
Wherein, can soar and be connected with the LED radiating end in the bottom of radiating tube, to keep air inlet unimpeded.
Wherein, when the LED radiating end was connected with the fin-shaped heat sink, radiating tube can be nested in the heat sink outside, and radiating tube bottom air inlet is kept unimpeded.
Wherein, when the LED radiating end was connected with the fin-shaped heat sink, radiating tube can directly be put solid above the fin-shaped heat sink.
The new a kind of LED lighting device radiator structure of this practicality, its advantage and effect are: this LED lighting device radiator structure, can make LED quicken heat radiation, prolong LED service life.

The main element explanation:
10-LED 11-radiating end 20-radiating tube
21-air inlet 22-gas outlet 30-heat sink
(5) specific embodiment:
Below in conjunction with accompanying drawing, specify as follows to the utility model content:
See also shown in Fig. 1,2, the utility model first embodiment soars into being connected with a tubulose radiating tube 20 (not limitting material) above the set LED10 radiating end 11 of LED lighting device, and radiating tube 20 is in bottom tool one air inlet 21, top tool one gas outlet 22.Whereby, the heat temperature meeting that makes LED10 radiating tube 11 is got rid of by gas outlet 22 after the rapid air inlet 21 by radiating tube 20 of energy enters because of cross-ventilation and radiating tube 20 tool stack effects, LED10 can be lowered the temperature, with the service life of prolongation LED10 rapidly.When the LED lighting device need be used plurality of LEDs 10, shown in visible Fig. 3,4, each LEDs 10 is connected in series.
See also shown in Fig. 5-7, the utility model second embodiment is applied to the structure chart that LED10 radiating end 11 is connected with fin-shaped heat sink 30.When the radiating end 11 of LED10 with after a heat sink 30 is connected, on heat sink 30, can wear a radiating tube 20 in heat sink 30 outsides (shown in Fig. 5-7), perhaps radiating tube 20 pendulum are fixed in heat sink 30 tops.The air inlet 21 of radiating tube 20 keeps unimpeded, and it is warm that LED10 radiating end 11 is conducted in the heat of heat sink 30, can quicken the up 22 eliminating coolings through the gas outlet, to prolong LED10 service life through the stack effect suction of top radiating tube 20.
Secondly, see also shown in Fig. 8-10, if LED10 radiating end 11 is connected with two or a plurality of heat sink 30, radiating tube 20 also can be provided with a plurality of thereupon, unimpeded at all nested radiating tube 20 in each heat sink 30 outside and maintenance radiating tube 20 bottom air inlets 21, make LED10 radiating end 11 pass to the heat temperature of heat sink 30, can attract via the stack effect of radiating tube 20, and up 22 dischargings through the gas outlet fast, making LED10 make the hot temperature that the time spent produces can reduce rapidly, to prolong LED10 service life.
Can illustrate by the foregoing description, no matter the utility model LED10 radiating end 11 directly connects radiating tube 20, perhaps after connecing heat sink 30, LED10 radiating end 11 connects radiating tube 20 again, radiating tube 20 all can be made the hot temperature tool suction that the time spent produces to LED10, the heat temperature of LED10 radiating end 11 can be discharged rapidly, has the effect that LED10 is lowered the temperature rapidly, to prolong LED service life.
