Specific embodiment
Embodiments of the invention are elaborated below, the present embodiment is implemented under premised on technical solution of the present invention, give detailed implementation method and specific operating process, but protection scope of the present invention is not limited to following embodiments.
The LED bulb and installation method of a kind of excellent radiation performance, including LED lamp bead 6, PCB lamp board 5, lamp holder 1 and lampshade 2, LED lamp bead 6 are welded in PCB lamp board 5, and lampshade 2 covers on the side that PCB lamp board 5 is welded with LED lamp bead 6, it is characterised in that:Radiator is set between lamp holder 1 and PCB lamp board 5,Radiator is by heat transfer plate 8,Hollow circular tube 4 and radiating fin 3 are constituted,Heat transfer plate 8 is arranged on the back side of PCB lamp board 5,Lamp hole 52 is provided with PCB lamp board 5,LED lamp bead 6 includes luminescence chip 61,Heat sink 62 and electrode 63,Luminescence chip 61 is arranged on heat sink 62,Electrode 63 electrically connects luminescence chip 61 with PCB lamp board 5,Heat sink 62 are welded on heat transfer plate 8 directly through lamp hole 52,Wire is set in hollow circular tube 4 to be used to be electrically connected between lamp holder 1 and PCB lamp board 5,The center of PCB lamp board 5 is provided with lamp plate hole 51,The center of heat transfer plate 8 is provided with heat transfer hole 81,Heat transfer hole 81 and lamp plate hole 52 connect with the tube chamber of hollow circular tube 4,The top-side of hollow circular tube 4 offers steam vent 41.It is designed to for the heat that LED lamp bead 6 is produced to be directly conducted to heat transfer plate 8 by above-mentioned, it is lost in air by radiator, the hot-air for being accumulated in lampshade 2 simultaneously can be scattered and disappeared by lamp plate hole 51, heat transfer hole 81 and hollow circular tube 4 eventually through steam vent 41.Such scheme can make full use of various heat exchange patterns to radiate, it is ensured that bulb is normally used.
Radiating fin 3 is stretched out by hollow circular tube 4, and steam vent 41 is provided with the tube wall of the hollow circular tube 4 between each layer of radiating fin 3.The quantity of steam vent 41 is arranged to multilayer, the hot-air convection in hollow circular tube 4 can be effectively helped, scattered and disappeared beneficial to heat.
Radiating fin 3 is bowl-shape in back-off, is radially extended downwardly by hollow circular tube 4.The bowl-shape radiating fin 3 of back-off can be collected into hollow circular tube 4 hot-air, finally discharged by the steam vent 41 of top, increased the speed air flow in hollow circular tube 4, so as to strengthen the effect of convection heat transfer' heat-transfer by convection, suction of the hollow circular tube 4 for hot-air in lampshade 2 can be strengthened, it is ensured that the operating temperature of LED lamp bead 6 is in normal range (NR).
Vertical fin convection holes 31 are offered on radiating fin 3.On the one hand the design of fin convection holes 31 increased radiating fin 3 with respect to area of dissipation, on the other hand also increase the flowing of hot-air between each layer radiating fin 3, improving radiating effect.
The length of radiating fin 3 is successively incremented by from lamp holder 1 to lampshade 2.The length of radiating fin 3 be successively incremented by lampshade 2 from lamp holder 1 such scheme can allow lamp profile close to conventional bulb shape, increase the scope of its application, on the other hand, closer to the position of lampshade 2, the temperature of radiating fin 33 is higher, the area of dissipation of needs is bigger, can so ensure effective radiating effect.
Lampshade convection holes 21 are provided with lampshade 2.During lampshade convection holes 21 can allow the cold air in the external world to timely enter lampshade 2, coordinate the drawing suction effect of hollow circular tube 4, stronger moving air can be formed in lampshade 2, strengthen radiating effect.
Lamp plate convection holes 53 are provided with PCB lamp board 5, heat transfer convection holes 82 are provided with heat transfer plate 8.Such design further helps heat to be scattered and disappeared from lampshade 2, the radiating effect of bulb is further strengthened.
The radiator is made by aluminium or copper material, good heat conductivity, beneficial to radiating.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, all any modification, equivalent and improvement made within the spirit and principles in the present invention etc. should be included within the scope of the present invention.
