The specific embodiment:

Do further explain below in conjunction with accompanying drawing.

Referring to Fig. 2, Fig. 3, solidus nail (11), lamp holder metal-back (9), connector (7), adapter sleeve (6), radiator (4), substrate (3), PC lampshade (1) are set from bottom to top.One end of lead (12), (13) is welded on the wire bonds end (20) on the substrate (3), and the other end of lead (12) is connected with solidus nail (11), and the other end of lead (13) is connected with lamp holder metal-back (9).

With reference to Fig. 4, Fig. 5; The material of the substrate of the utility model (3) is a pottery; The center of substrate (3) is the circle (17) of a hollow out, and described circle (17) is used to pass lead, and there are 3 substrate installing holes (18) at described substrate (3) edge; Be used to install screw (14), described screw (14) is fixed on substrate (3) on the radiator (4) tightly.

Substrate (3) inside is printed on circuit (schematic diagram is as shown in Figure 6); The surface connects electronic device (16); LED lamp pearl (2), rectifier bridge (23), PPTC are also posted from recovering devices (16) such as insurance (24), resistance, electric capacity in substrate (3) surface; LED lamp pearl (2) clocklike is distributed on the substrate (3), and effectively arrangement mode makes the light effect that goes out of LED lamp pearl (2) reach maximum.

Wire bonds end (20) at substrate (3) welds two leads (12) (13) respectively; Described two leads (12) (13) pass from the center cable-through hole (17) of substrate (3), pass radiator (4), adapter sleeve (6), connector (7) then successively, and this moment is referring to Fig. 8; The other end of said lead (13) is located outwardly-bent at the breach (8) of connector (7); The sweep copper cash is exposed, about exposed part 10mm, lamp holder metal-back (9) is turned clockwise on connector (7); Because the gap between connector (7) and the lamp holder metal-back (9) is very little, so the exposed copper cash of lead (13) is connected with lamp holder metal-back (9).Then described another root wire end is passed about 5mm from lamp holder afterbody central small hole (10); Peel the 5mm lead that passes off insulating barrier; Make it exposed and outwards bend 180 °, locate solidus nail (11) tightly this moment by being pressed in lamp holder afterbody central small hole (10).Like this, said lead (12) links together with solidus nail (11) tightly.

After connecting lead-in wire, with connector (7) and adapter sleeve (6) contraposition snap fit together, then adapter sleeve (6) and radiator (4) are passed installing hole (19) and combine through being connected screw (15).PC diffuser and radiator is bonding, so just accomplished assembling at last through glue.

Radiator (4) adopts aluminium or pottery etc. to be beneficial to the material of heat radiation; Basic shape type of the being taper tubular of said radiator (4); The cross section that area is big (21) is used for installation base plate (3); The middle adapter sleeve (6) of can packing in the cross section that area is little (22), the outer surface of said radiator (4) adopts the form of radiating fin (5), and radiating fin has increased the contact area of radiator (4) with outside air.

The substrate of the utility model (3) adopts ceramic material; Because the Heat stability is good, heat conduction of pottery are fast, insulation, environment friendly and pollution-free, price is low, so the heat that is produced by the inner devices (16) such as drive circuit, LED lamp pearl (2) and resistance of substrate (3) can pass to radiator (4) through substrate (3) very soon.Radiator (4) is heat transferred radiating fin (5), radiating fin (5) with heat fast and outside air carry out heat exchange.Simultaneously, adapter sleeve (6) inner hollow, the utility model designs driving power in substrate (3); Discharged the inner space of adapter sleeve (6); The heat that this method for designing not only makes light fixture produce at work can be passed to the external world fast, and can change the shape of radiator (4), adapter sleeve (6) as required, especially height, diameter; Change has taken place in the height of bulb lamp and diameter like this, has increased range of application.

Lamp holder metal-back (9) can adopt standard E27, B22, and GU10 etc. can directly replace existing fluorescent lamp, incandescent lamp etc.PC lampshade (1) can adopt conventional hemispherical, also the PC lampshade of other shapes can be installed as required, but be not limited to the PC material, also can be light transmissive materials such as glass.
