Embodiment Construction
[0012] As shown in FIG. 1, a reflective cavity 14 is provided on the heat sink 13. The reflective cavity 14 is a wedge-shaped structure with a large upper and a smaller bottom. The bottom plane is a rectangular plane, which is parallel to the upper surface of the heat sink, and the long sides are the same as those of the present invention. The two leads 17 of the special power LED for street lamps are connected to a solid vertical; the inner surface of the reflective cavity 14 is uniformly gold-plated or silver-plated, which can enhance the light-emitting efficiency of the diode; the reflective cavity 14 is pasted on an edge with two vias and inside The surface is evenly coated with a flat glass plate with YAG phosphor; there is a screw with a standard screw under the heat sink 13, which can be easily installed on the heat sink and has a good heat dissipation effect; the upper surface and the lower surface of the heat sink 13 form an α Therefore, the central light-emitting axis of...
