The specific embodiment
The self-heat irradiation device of this high-power LED illuminating lamp as shown in Figure 1, it is a kind of inventive improvements to existing LED illuminating lamp radiator.
This heat sink arrangement comprises lamp holder 1, radiator 6 and the cell-shell 3 of being with steam vent 1.1, and described radiator 6 is a hollow tube-shape radiator, and described cell-shell is the annular solid of a central ventilation road 5, the asymmetric upper shed of Internal and external cycle housing for the centre; Described heat radiation 6 devices are suspended at lamp holder 1 lower central by a fixed head 2, its underpart is connected with the inner ring housing of cell-shell 3 on fixing, be connected fixed head 2 equally, constitutes the integrated self-heat irradiation device from bottom to top that is made of exhaust 1.1 holes that are provided with on cell-shell central ventilation road 5, radiator hollow axial passage 8 and the lamp holder outer wall thus.
As the practical application (see figure 4) of above-mentioned basic structure, described self-heat irradiation device comprises lamp holder 1, radiator 6, cell-shell 3 and the ring-type photophore of being with steam vent 1.1; Described radiator is a hollow tube-shape radiator, and its underpart is provided with ring-type photophore or LED photophore, and described cell-shell 3 is the annular solid of a central ventilation road 5, the asymmetric upper shed of Internal and external cycle housing for the centre; Described radiator is suspended at the lamp holder lower central surely by a fixed head 2, its underpart is connected with the inner ring of cell-shell 3 on fixing, be connected fixed head 2 equally, constitutes the integrated self-heat irradiation device from bottom to top that is made of the steam vent that is provided with on cell-shell inner ring ventilating duct 5, radiator hollow axial passage 8 and the lamp holder outer wall thus.
In above-mentioned this heat abstractor, settle the ring-type photophore of led chip 7 to be arranged on radiator 6 bottoms, this moment, radiator 6 can adopt hollow fin shape radiator as shown in Figure 2, can accelerate heat dispersion by this hollow fin shape radiator.
As another version (see figure 5) of the practical application of above-mentioned basic structure, this moment heat abstractor basic structure, still comprise lamp holder 1, radiator 6, cell-shell 3 and the ring-type photophore of being with steam vent 1.1; Described radiator is a hollow tube-shape radiator, just ring-type photophore or led chip directly is provided with around the radiator outer ring of hollow form, and described cell-shell 3 is the annular solid of a central ventilation road 5, the asymmetric upper shed of Internal and external cycle housing for the centre; Described radiator is suspended at the lamp holder lower central surely by a fixed head 2, its underpart is connected with the inner ring of cell-shell 3 on fixing, be connected fixed head 2 equally, constitutes the integrated self-heat irradiation device from bottom to top that is made of the steam vent that is provided with on cell-shell inner ring ventilating duct 5, radiator hollow axial passage 8 and the lamp holder outer wall thus.
At the high-power LED illuminating lamp that above-mentioned this heat abstractor constitutes, will settle the ring-type photophore or the led chip of led chip 7 to arrange that around radiator 6 outer rings this moment, radiator 6 can adopt the barrel-shaped radiator of not being with radiating fin.
The inventive improvements of the self-heat irradiation device of this high-power LED illuminating lamp is embodied in three aspects:
One becomes the hollow tube-shape structure with fansink designs, has set up an inner core radiating surface for radiator, and this can accelerate radiating effect undoubtedly; In actual use, described hollow tube-shape radiator both can be provided with radiating fin 6.1 outside cylindrical shell; Also can only be that radiator 6 is designed to simple regular polygon hollow cylinder, as positive triangle, perhaps other regular polygon hollow cylinder.
Its two, the conventional collar plate shape support that led chip 7 is installed is designed to hollow circular ring shape support, make the led chip 7 that is placed on the hollow circular ring shape support, become the radiator structure of two-dimensional space by a radiator structure that utilizes conventional collar plate shape support; Ring-type photophore 4 shown in Fig. 1,3, not only can utilize the bottom of the annular support of settling led chip to give radiator with thermal energy transfer, simultaneously the side joint portion of radiator 6 that again can be by being nested with annular support utilizes the cold air that rises on the central ventilation road to reach the heat radiation purpose.
They are three years old, to be nested with by the ring-type photophore that annular support and led chip constitute after the radiator bottom, in conjunction with cell-shell is the central ventilation road that the annular solid at center forms, and makes that the steam vent that is provided with on the center tubular passage of radiator and the lamp holder outer wall constitutes from bottom to top jointly, from the inside to the outside integrated from radiator structure.Natural phenomena according to hot-air rises, cold air replenishes automatically will make this self-heat irradiation device be fully played.
In technique scheme, to the improvement of led chip supporting structure be played important function (wherein Fig. 2 for the AA of Fig. 1 to cutaway view, Fig. 3 for the BB of Fig. 1 to cutaway view) it has been broken, and general the heat sink of integrated high power LED conventional bracket is the mentality of designing of a disc in the traditional design, change the disk of single plane shape into middle porose anchor ring, the results showed that the punching support after this improvement has the following advantages:
A, increase cooling surface area can reach heat radiation, better faster in equal-wattage, identical heat radiation
Under the device condition, adopt the annular support after improving to make surface temperature descend 7%. This is very effective to prolonging product service life, improving reliability;
B, the contrast by two groups of white light products find that both luminous fluxes are very approaching;
C, can reduce the area that fluorescent material spreads out, improve the product hot spot;
D, can save backbone metal cost, plated material and packaging silicon rubber cost, guarantee overall product
Cost descends.
Obviously, adopt that technique scheme constituted by bulb shell in ventilating duct and the lower annular in the middle of top lamp holder steam vent, the middle part radiator constitute jointly from bottom to top, from the inside to the outside integrated from radiator structure, have extremely strong ventilation and heat effect, quick, the high efficiency and heat radiation that require when this works for led chip are very good.
