CN102252201A - Light-emitting diode (LED) ball-bulb lamp in convex-cup shape - Google Patents

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.

Technical field

The present invention relates to a kind of lighting apparatus, relate in particular to a kind of great power LED bulb lamp.

Background technology

LED is a kind of low voltage light sources, because its power saving, life-span is long, various low-voltage lighting devices now have been widely used in, the led light source module encapsulation construction that traditional LED bulb lamp often adopts generally comprises a metab with reflector, reflector bottom center at base is provided with some led chips, this led chip is bonded at the bottom center of reflector equably by welding manner or insulating cement, be in series by lead between the led chip or parallel connection after draw, be connected to the wiring board of the reflector outside that is arranged on the metab, make led chip be covered mixed layer inside fully after again the upper surface of led chip being applied glue and fluorescent material mixed layer.In above-mentioned traditional led light source module encapsulation construction, because needing lead-in wire between led chip and the wiring board is connected, but led chip is arranged on reflector inside, and wiring board is arranged on outside the reflector, therefore in the process of producing, be easy to make between led chip and the wiring board lead-in wire because of the people for bumping disconnected the damage, greatly reduce production efficiency, and it is more complicated that production process also becomes, and increases production cost.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of and can simplifies production process, saves the novel protruding cup structure LED bulb lamp structure of production cost.

The present invention is achieved in that a kind of protruding cup structure LED bulb lamp, comprise lamp holder, radiator, led light source and lampshade, described led light source comprises that one has the base of some reflectors, the reflector bottom is provided with at least one led chip, this led chip is bonded at the bottom of reflector by insulating cement, described reflector is surrounded by an annular projection, the sidewall of this reflector also is provided with an opening, also be concaved with a circuit board slot on the described base, this circuit board slot extends to respectively in the opening of reflector sidewall, circuit board slot below also is provided with a through hole, the embedded wiring board that is provided with of described circuit board slot, this wiring board extends in the reflector, and led chip is connected to wiring board by lead, and the led chip in the described reflector is coated with glue and fluorescent material mixed layer with the top that extends into the wiring board in the reflector opening.

The bottom of described circuit board slot is lower than the bottom of reflector.

The upper surface of described base is provided with a reflector layer of electroplating.

Described base and reflector are circle.

Described reflector is 6, and described circuit board slot is " king " font.

Described wiring board is pressed together by a glass flaggy and a line layer to be formed, and the line layer upper surface also is coated with the reflective white paint of one deck.

Described base adopts metal material to be stamped to form through one-shot forming technique.

The present invention has following advantage: protruding cup structure LED bulb lamp of the present invention, the encapsulation of its led light source module, adopt above-mentioned with led chip with extend into the wiring board of opening part of reflector and the lead between them, all be encapsulated in the encapsulating structure of the reflector inside below glue and the fluorescent material mixed layer, lead is from the back pass-out of metab, metab then adopts one-time formed technology to be stamped to form, be convenient in the operation of led chip encapsulation, just can finish in a direct step, improved the production efficiency of LED bulb lamp greatly, reduce the damage of lead in process of production, saved production cost.

The specific embodiment

The present invention will be described in detail below in conjunction with specific embodiment.

In the foregoing description, the base of described LED bulb lamp can be selected metal material such as aluminium sheet, the copper coin etc. of various high heat radiations, adopt the mould of making in advance to utilize one-shot forming technique, stamp out the solid shapes such as the reflector that is protruding cup-shaped, opening, circuit board slot and through hole that need, can enhance productivity greatly; And the shape of base also is not limited to circle, can do shapes such as squarely or strip, still can reach aforesaid goal of the invention.
