The specific embodiment

Below in conjunction with the drawings and specific embodiments, the bulb lamp the utility model proposes is described in further detail.

Embodiment mono-, please refer to Fig. 1, Fig. 2, and the present embodiment is a bulb lamp, is divided into from top to down lampshade 3, lamp socket 2, lamp holder 1 three parts in its main body.Light source adopts LED, LED described in the utility model can refer to the LED of encapsulation, encapsulation LED, surface mount LED, chip on board LED, comprise the LED of a certain type optical element.In the present embodiment, lamp holder 1 is standard lamp head, and lamp holder 1 is connected with lamp socket 2, and lamp socket 2 is for holding the circuit unit of driving LED.

Lamp socket 2 comprises a radiator 11 that serves as shell, and even heat plate 12 is arranged on one end that radiator 11 is connected with lampshade 3, and light source board 13 is arranged on even heat plate 12, and the heat that LED light source produces passes to radiator 11 by even heat plate 13, outwards discharges.

Lampshade 3 is spliced by heat conduction support 14 and optical element 15, heat conduction support has multiple laminated structures of stretching out from the contact-making surface of lampshade 3 and lamp socket 2, in the present embodiment, be 6, also can increase as required or reduce in other embodiments the quantity of laminated structure, or change it and be shaped as bar shaped or column, these laminated structures are extended to the top of lampshade 3 by lamp socket 2, prop up the bottom that overhangs lampshade 3.The top of lampshade 3 is optical element 15, and in the present embodiment, in order to realize wide-angle, optical element 15 scribbles reflecting layer for light-transmittance ceramics inner surface, and optical element can also adopt the combination of diffused component, phosphor element or other Various Components certainly.For the ease of optical element 15 is installed, the top of laminated structure is provided with a circulus 1401, and on optical element 15, comprise multiple buckles 1501, optical element 15, by the snapping of buckle 1501 and circulus 1401, makes the edge of optical element 15 contact and be connected with circulus 1401.Heat conduction support 14 while and lamp socket 2 heat transfer contact, are delivered to optical element 15 by the heat on lamp socket 2.In order to make optical element 15 have certain installation site, the height of heat conduction support 14 is less than the height of lampshade 3, because lampshade 3 is similar ball structure, in order to make circulus 1401 and optical element 15 contact-making surfaces only possible large, circulus 1401 is preferably positioned at spheroid cross-sectional periphery maximum, both the Lower Half of lampshade 3, the height that is to say heat conduction support 14 be less than lampshade 3 height 1/2nd.
