The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby protection domain of the present utility model is made more explicit defining so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that.
Referring to accompanying drawing 1 to accompanying drawing 4, flue type radiating LED illuminating device with honeycomb structure in the present embodiment by radiator 100, be arranged on the lighting unit 200 on this radiator 100 and the connecting portion 300 that is positioned on the radiator 100 is formed, wherein connecting portion 300 is used for being connected to support entire lighting device with lamppost.
Be formed with first installation portion 140 that is positioned at bottom surface middle part on the bottom surface 110 of radiator 100 and be closed around the end of any end of the cellular unit 130 of second installation portion, 150, the first installation portions 140 of first installation portion 140 and second installation portion, 150 tops.As a kind of preferred scheme, here thereby the middle part of radiator 100 bottom surfaces is recessed to form one to end face and is hexagonal depression and forms first installation portion 140, the bottom surface of hexagon depression is smooth, and will be positioned at the bottom sealing of the cellular unit of its top; Thereby the bottom surface of radiator 100 is recessed to form a ringwise groove in the position around the center to end face and forms second installation portion 150, the bottom surface of groove tilts to radiator 100 outsides, and will be positioned at the bottom sealing of the cellular unit of its top, be 5 degree～10 degree angles between bottom surface the best and the horizontal plane.
As shown in Figure 2, each cellular unit 130 is made up of the cell-wall 131 that 6 length equate substantially, and each cell-wall is attached on the cell-wall 131 of other cellular unit, thereby has constituted a kind of alveolate texture.Because the fact and theory are all with proof, honeycomb has adopted minimum raw material, but occupy maximum spatial area, and structural stability is best, therefore the utility model is owing to adopted alveolate texture to make the minimize weight of radiator 100, greatly saved raw materials for production, and greatly increased area of dissipation, structure is highly stable simultaneously.Preferably, the cell-wall length of each cellular unit is 5mm～10mm, and wall thickness is 0.5mm～1mm, thereby reaches the optimum balance effect of various aspects of performance.
It can be seen from the above, radiator 100 can adopt the mode of once making moulding to produce by metal material, also can be assembled by the aluminium flake after the moulding, and the preferred less metal material of casting aluminium material isodensity, thereby parameters such as the size of above-mentioned cellular unit 130, first installation portion 140, second installation portion 150, shape can specifically be determined by mould, once make moulding afterwards, production cost is lower.Here it may be noted that all and be, above-mentioned first installation portion 140, second installation portion 150 are not limited only to the structure in the present embodiment, for example first installation portion 140 can be circular fully, and second installation portion 150 also can be made up of a plurality of depressions around first installation portion 140 fully, illustrates no longer one by one here.
Connecting portion 300 is used for being connected with lamppost to support entire lighting device, is specially screwed hole in the present embodiment, can also be the multiple modes such as depression that the shape with lamppost is complementary.
With shown in the accompanying drawing 4, lighting unit 200 comprises the internal illumination lamp group 210 that is arranged on first installation portion 140 and is arranged on outside electroluminescent lamp group 220 on second installation portion 150 as accompanying drawing 3.Internal illumination lamp group adopts integrated packaged LED illuminace component for 210 groups, integrated packaged LED illuminace component adopts the form of integrated encapsulation, therefore a plurality of LED are packaged together, and power can be very big, forms central light source thereby integrated packaged LED illuminace component closely is fixed in the depression of first installation portion 140; Outside electroluminescent lamp group 220 in the present embodiment is made up of many haplotype LED illuminace components, these many haplotype LED illuminace components equidistantly distribute in the groove of second installation portion 150, because outward-dipping 5 degree～10 degree angles, the bottom of second installation portion 150, finally realized the process of luminous intensity distribution, intensity of illumination is evenly distributed in the light area, in addition, outside electroluminescent lamp group 220 also can adopt integrated packaged LED illuminace component.
Like this, when in running order following time, heat is respectively peritropous cellular unit 130 diffusions in center with place, luminous component place, when being diffused into each cellular unit 130 respectively, because hot-air density is less, move upward from the upper port outflow along cellular unit 130, and cold air can replenish into from lower port automatically; It can also be seen that in addition when being in the rainy day, rainwater can wash away cellular unit 130 automatically, thereby realized the function of automated cleaning.
