Fig. 1 is the structural representation of a kind of LED bubble lamp of the present utility model.
Fig. 2 is the decomposing schematic representation of a kind of LED bubble lamp of the present utility model.
Reference numeral comprises: plug 1, heat-dissipating casing 2, radiating fin 21, sealing ring 22, limited post 23, aluminium inserts 3, aluminium base 4, limited mouth 41, LED lamp pearl 5, lampshade 6.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is elaborated.
As depicted in figs. 1 and 2, a kind of LED bulb lamp of the present utility model, comprise plug 1, by high heat conduction, the heat-dissipating casing 2 that the heat-conducting plastic of high insulation is made, lampshade 6, LED lamp pearl 5, aluminium base 4 and the LED driver for powering to described LED lamp pearl 5, the quantity of LED lamp pearl 5 is some, each LED lamp pearl 5 is all installed on aluminium base 4, aluminium base 4 is arranged at the end face of heat-dissipating casing 2, particularly, aluminium base 4 is spirally connected with the end face of heat-dissipating casing 2, heat-dissipating casing 2 lateral surfaces are provided with for increasing heat radiation area to strengthen the radiating fin 21 of the heat dispersion of this bulb lamp, plug 1 is spirally connected with heat-dissipating casing 2 bottoms, lampshade 6 removably connects with heat-dissipating casing 2 tops, particularly, lampshade 6 can or be spirally connected with heat-dissipating casing 2 top clampings.The maximum outside diameter of lampshade 6 in the direction of the axis perpendicular to this bulb lamp is greater than the external diameter on heat-dissipating casing 2 tops, the lampshade 6 inner surfaces part reflective semitransparent film that has been sticked, to increase the reflection of lampshade 6 inner surfaces to light, so, the light that LED lamp pearl 5 is penetrated through the reflection rear section light of lampshade 6 inner surfaces, by heat-dissipating casing 2 top end faces, do not stopped and from heat-dissipating casing 2 tip edge shine LED bulb lamp of the present utility model after, thereby expanded the rising angle of LED bulb lamp of the present utility model.LED bulb lamp of the present utility model also comprises with heat-dissipating casing 2 and removably connecting, for strengthening the aluminium inserts 3 of the heat dispersion of this bulb lamp, aluminium inserts 3 is embedded in heat-dissipating casing 2, heat-dissipating casing 2 hollows, LED driver is arranged in aluminium inserts 3, aluminium inserts 3 lateral surfaces are coated with heat-conducting layer, this heat-conducting layer has slight viscosity, to allow aluminium inserts 3 lateral surfaces by the medial surface close proximity of described heat-conducting layer and heat-dissipating casing 2, thereby the contact area that guarantees heat-conducting layer and heat-dissipating casing 2 medial surfaces is enough large, allows aluminium inserts 3 give play to maximum heat-sinking capability.For the water resistance that increases LED bulb lamp of the present utility model is to increase its reliability when the outdoor application, LED bulb lamp of the present utility model is provided with the sealing ring 22 for waterproof in lampshade 6 and the junction of heat-dissipating casing 2, in the present embodiment, sealing ring 22 is made by the silastic material with good sealing property.In heat-dissipating casing 2 inside, set up the aluminium inserts 3 of heat conductivility excellence, strengthened the heat dispersion of LED bulb lamp of the present utility model, built-in aluminium inserts 3 is than existing external metal heat sink small volume, the metal material needing is less, so cost is lower, because aluminium inserts 3 is built-in, is the heat-dissipating casing 2 that insulating materials is made outside lamp body, easily by safety such as UL, CE, tests simultaneously.
Further, the maximum outside diameter of lampshade 6 in the direction of the axis perpendicular to this bulb lamp is greater than the maximum outside diameter that heat-dissipating casing 2 makes progress the party, thereby guarantees by lamp body, not stopped from the light of heat-dissipating casing 2 tip edge outgoing.
Further, LED bulb lamp of the present utility model also comprises that described LED lens cover on described LED lamp pearl 5 for regulating the LED lens of the hot spot of described LED lamp pearl 5 ejaculations.Because the light of LED lamp pearl 5 outputs is comparatively concentrated, disperse not, and the adjusting of the hot spot that 6 pairs of LED lamps of lampshade penetrate is very limited, so the hot spot that LED lens regulate LED lamp pearl 5 to penetrate is set, can obtain better hot spot regulating effect.
Wherein, heat-dissipating casing 2 end faces are provided with for giving the spacing limited post 23 of aluminium base 4, the position of the aluminium base 4 corresponding described limited posts 23 in edge offers limited mouth 41, described limited post 23 cooperatively interacts with limited mouth 41, to prevent that aluminium base 4 from sliding on heat-dissipating casing 2 end faces, also there is the effect to aluminium base 4 location simultaneously.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not restriction to the utility model protection domain; although the utility model has been done to explain with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the technical solution of the utility model, and not depart from essence and the scope of technical solutions of the utility model.
