1. An LED light source, comprising:a base, comprising an upper edge, a light emitting region formed and enclosed by the upper edge, an inner mounting surface concavely formed on the base and along the upper edge, and a reflective layer disposed on the inner mounting surface;
at least an LED chip, combined with two metal wire bonds and installed at a bottom position of the inner mounting surface by solid-crystallization;
an anti-vulcanization structure, continuously and uninterruptibly formed on the reflective layer, the metal wire bonds, and a surface of the LED chip;
a light excitation structure, including at least a fluorescent powder containing an element selected from the group consisting of sulfur, lead, and phosphorus, and the light excitation structure being installed in the base;
an encapsulation structure, installed in the base, for packaging the light excitation structure and the LED chip in the base, and the anti-vulcanization structure isolating the reflective layer, the metal wire bonds and the LED chip from directly contacted with the encapsulation structure, and the encapsulation structure being made of organic silicone and containing a platinum catalyst;
a protection structure, installed at the base by a dispensing method and covering the encapsulation structure; wherein the encapsulation structure has a hardness lower than the protection structure; and
a plurality of uniform light particles scattered in the protection structure, and the uniform light particle being one selected from the group consisting of SiO2, BN, Al2O3, and TiO2 or a combination thereof,
wherein the LED chip has a light emission wavelength falling within a range of 400-460 nm, and the light excitation structure comprises a green fluorescent powder, a first red fluorescent powder and a second red fluorescent powder, and the green fluorescent powder contains sulfur, and the first red fluorescent powder does not contain sulfur, and the second red fluorescent powder contains sulfur; the first red fluorescent powder is selected from the group consisting of T2XF6:Mn4+, M2Si5N8:Eu2+, and CaAlSiN3:Eu2+; T is selected from the group consisting of Li, Na, K, and Rb, and X is selected from the group consisting of Ge, Si, Sn, Zr, and Ti; M is selected from the group consisting of Ca, Sr, and Ba; and the second red fluorescent powder is selected from the group consisting of CaS:Eu2+, SrS:Eu2+, Ba2ZnS3:Mn2+, and a red quantum dot.
