Common LED product generally by increase the mixed light cell-shell of serious offense hemisphere before the LED illuminating source, reaches the illuminating effect of accurate full luminous intensity distribution.These class methods are brought the problem of two aspects: 1, the cell-shell of serious offense hemisphere only can realize that angle greater than the illumination of 180 ° wide-angle, can not satisfy full luminous intensity distribution product requirement; 2, under the standard sources dimensional requirement, the excessive LED drive part insufficient space that causes in cell-shell space brings certain difficulty to drive part electronic circuit product design in the product.Also have at present by methods such as reflections and realize the full luminous intensity distribution of LED product, but reflection brings the reduction of optical efficiency to make the product overall performance can not reach perfect condition.
The utility model content
The purpose of this utility model is exactly to provide a kind of drive part space full luminous intensity distribution type that wide-angle large, that can realize standard sources is thrown light on from ballast LED lamp for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of full luminous intensity distribution type is from ballast LED lamp, comprise top cover, cell-shell, light source assembly, drive circuit, fin and lamp adapter assembly, described top cover, cell-shell and lamp adapter assembly connect and compose lamp body, described light source assembly and drive circuit are located in the described lamp body, described LED lamp also comprises the center ring that is located in the lamp body, described lamp body is divided into upper illumination cavity and lower illumination cavity by center ring, described light source assembly comprises upper light source board and the lower light source board that is located on the center ring, described upper light source board and lower light source board lay respectively in illumination cavity and the lower illumination cavity, and connect drive circuit.
Described center ring comprises cylindrical portion and the annulus section that is located on the cylindrical portion, described lamp body partly is divided into upper illumination cavity and lower illumination cavity by this annulus, described upper light source board is located at the upper surface of annulus section, described lower light source board is located at the lower surface of annulus section, and described drive circuit is located in the cylindrical portion.
Described top cover is connected to the upper end of cylindrical portion, and described fin is located at the lower end of cylindrical portion.
Described lamp adapter assembly is located at the lower end of cylindrical portion, comprises lamp holder plastic piece and lamp holder.
Described cell-shell comprises for the upper cell-shell of the upper illumination cavity of sealing and is used for sealing the lower cell-shell of lower illumination cavity.
The inner surface of described upper illumination cavity and lower illumination cavity carries out reflective processing or reflecting part is set.
Compared with prior art, the utility model is by arranging upper light source board and lower light source board throws light on to up and down two parts of LED lamp respectively, can realize the wide-angle illumination, because the cylindrical portion of center ring runs through whole lamp body, the drive circuit of driving LED can be arranged in this cylindrical portion, so that the space that is used for the configuration driven circuit is obviously greater than the common LED lamp, thereby more complicated drive circuit can be installed, realize the various complex controls such as light modulation, remote control.
