Led light source, led light source manufacturing method, and direct display device thereof

An LED light source manufacturing method, comprising the steps of:

• providing a base having an upper edge, a light emitting region formed and enclosed by the upper edge, and an inner mounting surface inwardly and concavely formed on the base along the upper edge;
• forming a reflective layer on the inner mounting surface;
• providing at least an LED chip installed at a bottom position of the inner mounting surface by a flip chip method or combining two metal wire bonds by a solid crystallization method;
• injecting a low-viscosity and high-volatilization anti-vulcanization solvent to the inner mounting surface of the base, so that the anti-vulcanization solvent completely covers all metal materials on the inner mounting surface;
• resting or heating to volatize the anti-vulcanization solvent to form an anti-vulcanization structure, and the anti-vulcanization structure being in a continuous and uninterruptible thin film state;
• providing a light excitation structure including at least a fluorescent powder containing one selected from the group consisting of sulfur, lead, and phosphorus, and the light excitation structure being installed in the base;
• packaging the light excitation structure and the LED chip by an encapsulation structure, and the anti-vulcanization structure isolating all metal materials on the inner mounting surface from directly contacting with the encapsulation structure, and the encapsulation structure being made of organic silicone and containing a platinum catalyst;
• and
• dispensing a protection structure to the base and covering the encapsulation structure;
• wherein the encapsulation structure has a hardness lower than a hardness of the protection structure.
