Abstract
The utility model relates to the field of illumination lamps and lanterns, in particular to a light-emitting diode (LED) bulb. The LED bulb comprises a lamp base, a lamp shell and a lamp cap. The bottom end of the lamp shell is connected with the lamp base, a circuit board and a power converter capable of converting alternating currents into direct currents are arranged in the lamp shell, and a plurality of LED lamp beads are arranged on the top surface of the circuit board. The circuit board is connected with the power inverter through a guide line, and the power inverter is connected with the lamp base through a guide line. The LED bulb is characterized in that an annular table protruding inwards is arranged on the inner side wall of a top opening of the lamp shell; the circuit board is circular in shape and is arranged on the annular table, and the edge of the circuit board is in clearance fit with the inner side wall of the top opening of the lamp shell; the bottom edge of the lamp cap and the top opening of the lamp shell are assembled together through a buckled manner; and the lamp cap is a frosted lamp cap through sand grinding processing and is semispherical. The LED bulb is simple in structure, flexible in dismantling and mounting, saving in material, energy-saving, environment-friendly, and long in service life.
Description
Technical field
The utility model relates to field of illuminating lamps, specifically, relates to a kind of LED bulb.
Background technology
The LED bulb is a lighting installation commonly used such as lighting engineering, square, park, large-scale nightclub and public place of entertainment.Existing LED bulb product generally can use screw when assembling, make dismounting cumbersome, moreover, containing insoluble plastic material in the existing LED bulb more, can't be recycled, be unfavorable for energy-conserving and environment-protective.
The utility model content
The technical problems to be solved in the utility model is to overcome above-mentioned defective, provide a kind of simple in structure, dismounting flexibly, the LED bulb of economical with materials, energy-conserving and environment-protective, long service life.
For addressing the above problem, the technical scheme that the utility model adopted is:
A kind of LED bulb comprises lamp holder, lamp housing and the crown top of burner, and the bottom of described lamp housing is connected with lamp holder, is provided with circuit board in the lamp housing and alternating current can be changed into galvanic power supply changeover device, and the end face of circuit board is provided with several LED lamp pearls; Described circuit board is by the wire connecting power converter, and power supply changeover device connects lamp holder by lead, it is characterized in that: the open-topped madial wall of described lamp housing is provided with the annular table to convex; Described circuit board be shaped as circle, place on the annular table the open-topped madial wall matched in clearance of its outer rim and lamp housing; The bottom margin of the described crown top of burner and the open top of lamp housing by the card and mode fit together.
The frosted crown top of burner of the described crown top of burner for handling through frosted, it is shaped as hemispherical.
The top of described lamp housing closely is arranged with 18 louvres.
The number of described LED lamp pearl is 12.
Beneficial effect: compared with prior art, advantage of the present utility model is: 1, main card and the assembling form of adopting, and simple in structure, dismounting is flexible; 2, the frosted crown top of burner can make LED lamp pearly-lustre be radiated at the surface and form the diffuse reflection shape, and then the light that makes light irradiation come out is soft, and not dazzling, light effects is also more soft and graceful, and, the more common material of airtight performance of the frosted material crown top of burner good; 3, do not contain insoluble plastic material, energy-conserving and environment-protective can be recycled; 4, long service life.
