Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Referring to Fig. 1, the invention provides a kind of fin slices radiator, the fin slices radiator is applied to the radiator structure of LED,
It includes hollow connector 10 and is connected in the hollow connector 10 and combines a plurality of fin 20 for forming plate-like, dissipates
The bottom of backing 20 is provided with installation base plate 30.In concrete application, lamplight component is located at the lower section of substrate 30, during LED operation,
Due to fuel factor, air formation free convection, the fluid density of high-temperature is relatively low, can gentlier move upwards.Opposite, temperature is low
Fluid then move downward.So be that fluid is heated produces driving force afterwards, as long as there is the temperature difference, along the fluid of gravity field direction
Will setting in motion, fully take away heat.Radiating effect is so substantially increased, radiator is had in space and is evenly distributed
Fluid for radiating heat feature so that LED/light source is radiated well, so as to also substantially increase LED/light source working life.
With reference to Fig. 2A and Fig. 2 B, fin 20 of the invention includes the space bar 21 and deflector 22 being connected with each other, and institute
State space bar 21 and deflector 22 is equipped with even number and is used for the through hole 201 of air circulation, the flowing of air can be improved whereby
Performance and area of dissipation, improve radiating efficiency.
Space bar 21 is main heat sink, and it has larger area of dissipation.Deflector 22 combines to form double L-shaped with space bar 21
Radiator structure, not only further increase area of dissipation, can more preferable cooling with more guide functions.
Preferably, the inner of deflector 22 is provided with respectively to the first fin 221 of both sides bending and molding and the second fin
222.First fin 221 connects space bar 21, and the second fin 222 abuts adjacent space bar 21.Whereby, fin slices radiator is scattered
Form " mutual zip mode " formation between backing 20 to interlock, mutual convection current and effective radiating of increased area.In addition, a plurality of radiatings
One " heronsbill " formula topological network shape of formation of piece 20, is evenly distributed, forms rapid and natural convection space, greatly improves radiating effect
Rate.
To increase the water conservancy diversion effect of deflector 22, the first fin 221 vertical the place plane of space bar 21, the second fin
The 222 vertical place planes of deflector 22.
In the concrete application of the present invention, with reference to Fig. 3, the hollow connector 10 is preferably cylindrical shape, and space bar 21 passes through
Interface arrangment coordinates with hollow connector 10.Space bar 21 has intersection, and intersection position with the plane where deflector 22
In on the axis of the hollow connector 10, the entirety that fin slices radiator is caused whereby is the divergence expression structure of rule.
In addition, the space bar 21 of the present invention is can be with integrated formed structure with deflector 22, can also two blocks of independent plates
Card processing is combined, and the two preferably adopts aluminium sheet material, and thickness is 0.6mm, is only 1/3rd of traditional aluminium radiator fin
Left and right, reduces product weight.
The present invention, which is correspondingly provided, a kind of includes the LED of foregoing fin slices radiator.With reference to Fig. 4, before the LED is except including
Outside the radiator stated, in addition to light engine module.It is that LED/light source reference SMD paster solder reflow process is welded on into aluminium base
On plate, formed using uniform brush of High thermal-conductive silicone grease covering in aluminium base bottom.
The installation base plate 30 of light engine module and fin slices radiator is closely connected, reduces thermal resistance, thermal source is kept off by aluminium
Plate (installation base plate 30) uniformly distributes thermal source on heat source to a plurality of longitudinal biplate L-shaped fins.While aluminium shelves
Plate only remaining LED light engine aluminium base Board position and screw hole site, residue is all by hollow out, to be formed with longitudinal biplate L-shaped fin
Piece greatly reduces windage, makes integrated air convection current more quick effective, so that very fast reduction temperature.
LED PMMW optical lenses as beyond lid on fin slices radiator and protection light engine module, also may be used by the present invention
Required illumination optical is provided with the application places for user, the optical lens, which is adopted, to be screwed on fin slices radiator.
Preferably, LED of the invention can combine four to form Assembled lamp.Specifically, being radiated by four lamp holder modules
The rotation axle bolt of device base is connected with four-head connecting cantilever support to be fixed, and the linking rotating device includes：Base rotates spiral shell
Bolt, nuts, meson, bullet are situated between and nut.Passed through by the rotation axle bolt of lamp holder base convex to outside pole bracket by inside
Shape elongated hole shape, the meson, bullet are situated between, nut will be installed in its three makes with fixation into base rotation axle bolt, then by bolt
Locked on cap.Remaining three lamp holder same structure relation progress implementation connection described above simultaneously, and pole bracket
Convex elongated hole shape, it is 15 degree that lamp holder transverse rotation angle, which is presented, and meeting can be adjusted in application using irradiation corresponding places
Demand illumination.Corresponding, the present invention installs four LED constant pressure and flow Switching Power Supplies, respectively for giving four LED lamp holder modules steady
Fixed work.The lamp body mounting bracket of the present invention, installs adjusting bracket, hex bolts, meson, bullet by U-shaped mounting bracket, L-shaped and is situated between
With nut parent.Adjusting bracket mirror is installed to fixation in centre position and L-shaped on the outside of pole bracket, the L-shaped installs adjusting bracket
7 mounting hole sites are distributed as giving U-bracket to fix, hex bolts is pierced into L-shaped from outside adjusting bracket and U-shaped installation is installed
Support, the meson, bullet, which are situated between, nut will pierce into hex bolts in it makes mounting bracket, and L-shaped install adjusting bracket with
120 degree are uniformly distributed 7 mounting holes, are that the U-shaped mounting bracket supplies to give flexible modulation to install.
Whereby, the present invention realizes following beneficial effect：
1) product material weight is reduced.Specifically, in Same Efficieney, than aluminium section bar as cooling system by contrast most
1/3rd or so weight is reduced less.
2) highly effective air Natural Heat Convection is used, integral heat sink system plays efficiently quick fluid certainly with largest optimization
Right heat loss through convection, reduces windage, larger fluid flow channel.Realize LED/light source can at preferable temperature steady operation, equal
Under power, its radiator temperature will at least be less than 13% compared to before.
3) four lamp holders and mounting bracket can adjust, and be available for setting angle and irradiating angle flexible Application.
In summary, the present invention is by setting a hollow connector, and some groups of clamping is uniform around hollow connector
A plurality of fin of arrangement, wherein each fin includes the space bar and deflector being connected with each other, the two constitutes double L-shaped knot
Structure, and the space bar and deflector are equipped with even number is used for the through hole of air circulation, whereby to realize high efficiency and heat radiation.
Certainly, the present invention can also have other various embodiments, ripe in the case of without departing substantially from spirit of the invention and its essence
