Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of LED flashlight of the present invention is described in further detail:
As shown in Fig. 1,2,3, LED flashlight of the present invention, include cylinder 1, in its cavity, be used for installing battery, use
Aluminium manufactures.Being provided with a large-power light-emitting diodes on heat conducting base 2, this light emitting diode has one in disc-shaped
Aluminium base 3, heat conducting base 2 front end be provided with one slightly larger than circular counter bore in disc-shaped aluminium base 3, aluminium base 3 posts
In the circular counter bore of heat conducting base 2, make the heat energy on aluminium base 3 can be directly conducted in bottom and the surrounding of heat conducting base 2.
Heat conducting base 2 is arranged on heat-conducting cylinder 4 medial wall, and first the heat energy on heat conducting base 2 can conduct to heat-conducting cylinder 4 medial wall,
Conduct outside sidewall the most again.Heat conducting base 2 and heat-conducting cylinder 4 use aluminium manufacture, not only have good heat conductivility, and
It is easy to processing.Heat-conducting cylinder 4 tail end is fixed on the front end of cylinder 1, owing to heat-conducting cylinder 4 and cylinder 1 are made by aluminium, and heat-conducting cylinder
Heat energy on 4 can rapidly from tail end conduction to cylinder 1 front end.Owing to heat energy is from the bottom of the counterbore of heat conducting base 2
Facing out, hold conduction further along, then transmit the most backward through the medial wall of heat-conducting cylinder 4, now heat energy is transferred to cylinder
Temperature on body 1 front end has become the lowest.Heat conducting base 2 is provided with the circular radiating tube 5 extended back, inside heat-conducting cylinder 4
Wall is rounded, and the heat energy on heat conducting base 2 can also conduct to heat-conducting cylinder 4.Radiating tube 5 with inside corresponding heat-conducting cylinder 4 between
It is provided with the circular heat-dissipating space 6 being isodistantly spaced, so so that heat energy is uniformly dispersed in heat-dissipating space 6.Through hole 7 is at least
Being two, be isodistantly spaced setting, the heat-conducting cylinder 4 in LED flashlight of the present invention is provided with four symmetrically arranged through holes 7, Mei Getong
Hole 7 all passes to heat-dissipating space 6, forms convection channel, it is simple to air flows at four direction.So the heat energy on radiating tube 5 is then
Can be distributed in heat-dissipating space 6 by its appearance, the heat energy part on heat-conducting cylinder 4 is then outwardly expanded by it
Dissipating, another part then distributes towards heat-dissipating space 6 by inside it, distributes together with the heat energy to heat-dissipating space 6 with radiating tube 5
Discharged by the convective exchange of air.
During work, a large amount of heat energy produced after light emitting diode energising are first focused on aluminium base 3, due to aluminium base 3
Adhering on heat conducting base 2, heat energy is then by the form conduction of conduction of heat to heat conducting base 2.Lead owing to heat conducting base 2 is placed in
On inside hot cylinder 4, so, heat energy will continue through the conduction of heat conducting base 2 and heat-conducting cylinder 4 interior side contacts position to and diffuse to whole
On individual heat-conducting cylinder 4.Now, heat conducting base 2 lateral surface, all there is heat energy the inside and outside side of heat-conducting cylinder 4 to external diffusion, the surface of heat radiation
Amass and become the biggest.Through hole 7 on heat-conducting cylinder 4 forms exhaust passage with heat-dissipating space 6, can be by the heat energy in heat-dissipating space 6
Discharged by the form of convection current.Particularly when LED flashlight is in horizontal or slant setting, this state LED flashlight the most just
Often in the state in using, now, there are through hole 7, so, heat-dissipating space 6 all the time in the upper and lower position of heat-conducting cylinder 4
In hot-air then can upwards be automatically drained out, cold air around then can be from the through hole 7 of following and both sides automatically into, through hole
7, heat-dissipating space 6, through hole 7 define the gas channel of about, can form hot and cold air and automatically exchange, and play quickly
The technique effect of heat radiation.
Owing to light emitting diode becomes less compared to traditional bulb luminous source, its volume, vacate for lamp holder position
Bigger space, therefore, this structure takes full advantage of the space vacateed compared to prior art, it is provided that have one times with
On cooling surface area, keep prior art torch contour structures on the basis of, greatly reduce the table at its lamp holder position
Surface temperature, improves the service life of light emitting diode, and on the basis of same overall dimensions, it is also possible to install or increase
More powerful light emitting diode.
