The specific embodiment
Bulb lamp of the present invention in order to improve the radiating effect of LED bulb lamp, is offered a smokestack passage in LED bulb lamp, by the air-flow that flows into this smokestack passage, LED bulb lamp is dispelled the heat.
LED bulb lamp of the present invention, referring to Fig. 1, Fig. 3, Fig. 6 and Fig. 7, it comprises: lamp holder 10, insulating base 20, heat abstractor 30, illuminator 40 and the power module 50 of powering to illuminator 40; Wherein, described lamp holder 10, insulating base 20, heat abstractor 30 and illuminator 40 are sequentially fixedly connected with successively.In bulb lamp, be provided with a smokestack passage, this smokestack passage runs through described heat abstractor 30 and illuminator 40, for LED bulb lamp provides an internal gas flow circulation passage, utilizes Air Flow to take away the heat that LED bulb lamp produces.
Further, referring to Fig. 2 and Fig. 7, described heat abstractor 30 is provided with first passage 31, on described illuminator 40, is provided with second channel 46 with these first passage 31 correspondence positions, and this second channel 46 is communicated with the described smokestack passage of formation with first passage 31.
Further, referring to Fig. 1 and Fig. 3, described insulating base 20 is provided with multiple through holes 21, and each through hole 21 and smokestack channel connection make the thermal current of smokestack passage in LED bulb lamp shed with prestissimo.Described multiple through hole 21 is evenly distributed on described insulating base 20 with the circular arc spacing of fixing, and makes the heat radiation of LED bulb lamp evenly.
Further, referring to Fig. 3, Fig. 4 and Fig. 5, the matrix 34 of described heat abstractor 30 is tubular setting, and the peripheral, axial of this matrix 34 is provided with the first radiating fin 32, and the axial length of this first radiating fin 32 is less than the axial length of matrix 34.One end that these matrix 34 axial lengths go out the first radiating fin 32 axial lengths is fixedly connected with illuminator 40.This first radiating fin 32 is set to one or more, and is uniformly distributed with the circular arc spacing of fixing.
Further, referring to Fig. 4, Fig. 5, on first passage 31 inwalls of described heat abstractor 30, be provided with the second radiating fin 33 along the axial length direction of matrix 34.This second radiating fin 33 is set to one or more, distributes, and be vertically installed on the inwall of first passage 31 with the circular arc spacing of fixing.
Further, described heat abstractor 30 is made by metal material, is made best by metallic aluminium.The heat that this heat abstractor 30 is mainly used in power module 50 and illuminator 40 to produce dispels the heat.
