The specific embodiment

Below in conjunction with drawings and Examples, utility model is described in detail.

In the first embodiment, as shown in Figure 1, the LED plug-type electricity-saving lamp that the utility model proposes, comprise lamp holder 7, base 6, be plugged on the lampshade 2 on base 6 and be arranged on the interior light source of lampshade 2, wherein, this light source is four PCB circuit boards 4 that surround cylindricality, light-emitting area is installed outwardly on it and LED lamp pearl 3 up.

The rear end of base 6 is connected with lamp holder 7, and lamp holder 7 adopts hickey, can certainly be the lamp holder joints of other models.Be plugged with four parallel PCB circuit boards 4 and lampshade 2 on the front end face of base 6, pcb board 4 is welding one row LED lamp pearl 3 on the face of direction outwardly, and the width of LED lamp pearl 3 is half of pcb board 4 width, and place at its interval on pcb board 4.

To shown in Figure 5, lampshade 2 be semicircle or square as Fig. 1, adopts the insulation light transmissive material to make, its outside thickening, the inboard be provided with two relative, for the fixing spill deck 9 of PCB circuit board 4, PCB circuit board 4 is embedded between two decks 9; LED lamp pearl 3 is located between PCB circuit board 4 and lampshade 2.

Top cover 1 for thin rounded flakes or other shape identical with lampshade 2 cross sections, is fixed on the top of lampshade 2 and is connected with it, adopts the insulation light transmissive material to make.To shown in Figure 5, no matter lampshade 2 and top cover 1 are to be shaped to one as Fig. 1, and perhaps separable assembled, all leave the gap between lampshade.
