The invention provides a high-power light-emitting diode (LED) ball-bulb lamp structure and belongs to the field of processing of lighting equipment. The high-power LED ball-bulb lamp structure comprises a lamp cup, a radiator, an LED light source in a convex-cup shape and a lamp shade, wherein the LED light source in the convex-cup shape comprises a base having a plurality of reflecting cups; at least one LED chip is arranged at the bottom of each reflecting cup; and the LED chip is adhered to the bottom of the reflecting cup by an insulating adhesive. The high-power LED ball-bulb lamp structure is characterized in that: each reflecting cup is formed by enclosing an annular bump; an opening is formed in a side wall of the reflecting cup; a circuit board groove is recessed in the base; the circuit board groove extends to the openings in the side walls of the reflecting cups respectively; a through hole is formed below the circuit board groove; a circuit board is embedded into the circuit board groove; the circuit board extends into the reflecting cups; the LED chips are connected to the circuit board by leads; glue water and fluorescent powder mixed layers are coated above the LED chips in the reflecting cups and the circuit board which extends into the openings of the reflecting cups.
Description
Technical field [0001] The invention relates to a lighting device, in particular to a high-power LED bulb lamp. Background technique [0002] LED is a low-voltage light source. Because of its power saving and long life, it has been widely used in various low-voltage lighting devices. The LED light source module packaging structure often used in traditional LED bulbs generally includes a metal with a reflector. In the base, a number of LED chips are arranged at the bottom center of the reflector cup of the base. The LED chips are evenly adhered to the bottom center of the reflector cup by welding or insulating glue. The LED chips are connected in series or parallel through wires and then led out to connect to the set On the circuit board outside the reflector cup on the metal base, the upper surface of the LED chip is coated with a glue and phosphor mixed layer so that the LED chip is completely covered inside the mixed layer. In the above-mentioned traditional LED light source m...
