Embodiment

Do to describe in detail with next preferred embodiment and conjunction with figs.:

See also Fig. 2～5, be a kind of power led light source assembly of the utility model, this power led light source assembly comprises:

As Fig. 1, shown in Figure 4, one pedestal 10, form a depressed part 101 on this cylindrical pedestal 10, be provided with a projection 102 (shown in Figure 4) in this depressed part 101, these pedestal 10 peripheries are interval with plurality of through holes 103, and pedestal 10 sidewalls are provided with threaded portion 104 and teat 109, and these pedestal 10 bottom surfaces are provided with various groove 105,106,107 and go out wire casing 108.

As shown in Figure 3, one light-emitting diode 20, these light-emitting diode 20 bottom surfaces are in conjunction with a circuit board 21, and this circuit board 21 is provided with a perforation 211, be arranged at for light-emitting diode 20 bottom surfaces on the projection 102 of this pedestal depressed part 101, and be equipped with lead 22 on this circuit board 21, to be arranged in this pedestal 10, pass and go out wire casing 108 by this.
