Traditional LED lamp comprises lamp holder, circuit board, led light source, lampshade, and it is two power connection points that the electric power of lamp holder connects input.Tradition LED lamp generally uses the input of electron rectifier AC power to be converted to dc source, but traditional LED lamp heat dispersion is bad, the long-term electron rectifier that uses is easy to overheated generation abnormal current, and this may cause damage to electron rectifier itself and led light source.In addition, because the operating frequency height of electron rectifier, can produce high-frequency harmonic and electromagnetic interference during use, therefore, if a large amount of LED lamps adopts electron rectifier, will produce huge harmonic wave and electromagnetic interference to power system so, thereby have a strong impact on the quality of power supply, do not meet the energy-conserving and environment-protective design concept of present promotion, so people wish to have a kind of LED lamp that stable direct current can be provided, not pollute the quality of power supply.
The utility model content:
The purpose of this utility model is exactly the deficiency that exists at prior art and provide a kind of and utilize the magnetic closed loop characteristic of coil to reduce high-frequency harmonic and electromagnetic interference, constant DC stream is provided, does not pollute the LED lamp of the quality of power supply.
To achieve these goals, the technical solution adopted in the utility model is: a kind of LED lamp, it comprises that lamp holder, lid are located at the diffuser on the lamp holder, it also includes the circular coil of the light source board, circuit board and the hollow that are arranged on the lamp holder from top to bottom, the electric power that the input of circular coil is electrically connected lamp holder connects input, its output is electrically connected the input of circuit board, is embedded with a plurality of led light sources on the light source board, and the input of led light source is electrically connected circuit board.
Described diffuser is a frosted spherical glass cover.
Described circular coil comprises iron core, elementary winding and secondary windings, and elementary winding and secondary windings are wrapped on the iron core, and the electric power that the two ends of elementary winding connect lamp holder connects input, the input of the two ends connecting circuit plate of secondary windings.
Described iron core is a loop configuration.
Evenly form plurality of grooves on the described light source board end face, led light source is embedded in the groove.
The utility model beneficial effect is:
A kind of LED lamp that the utility model provides, it comprises lamp holder, lid is located at the diffuser on the lamp holder, it also includes the light source board that is arranged on the lamp holder from top to bottom, the circular coil of circuit board and hollow, the electric power that the input of circular coil is electrically connected lamp holder connects input, its output is electrically connected the input of circuit board, be embedded with a plurality of led light sources on the light source board, the input of led light source is electrically connected circuit board, the utility model utilizes the magnetic closed loop characteristic of circular coil, can reduce high-frequency harmonic, electromagnetic interference and reduction D.C. resistance, for circuit board provides comparatively pure dc source, the circular configuration of circular coil helps reducing volume and stable electric power can be provided, and belongs to green, environment-friendly products.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a decomposing schematic representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see shown in Fig. 1 to 2, the utility model comprises that lamp holder 1, lid are located at the diffuser 2 on the lamp holder 1, diffuser 2 can be selected frosted spherical glass cover or not frosted according to user's needs, diffuser 2 after the frosted makes that light can be not dazzling, lamp holder 1 is screw socket 1 or socket lamp holder 1, and can select model according to different needs is screw socket 1 or the standard socket lamp holder 1 of E27, E14.The utility model also includes the circular coil 5 of the light source board 3, circuit board 4 and the hollow that are arranged on the lamp holder 1 from top to bottom, the electric power that the input of circular coil 5 is electrically connected lamp holder 1 connects input, its output is electrically connected the input of circuit board 4, be embedded with a plurality of led light sources 6 on the light source board 3, the input of led light source 6 is electrically connected circuit board 4, led light source 6 is 6 in the present embodiment, can certainly other quantity, include the drive circuit of driving LED light source 6 on the circuit board 4.
