Description

Full luminous intensity distribution type LED lamp
Technical field
The present invention relates to a kind of LED lamp, especially relate to a kind of full luminous intensity distribution type LED lamp.
Background technology
At present, use LED to be widely used as the illuminating product of light source, LED class illuminating product is because the luminous characteristic of its one direction is used to accent light mostly.
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 is greater than the wide-angle illumination of 180 °, can not meet 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, bring certain difficulty to drive part electronic circuit product design in product.Also have by methods such as reflections and realize the full luminous intensity distribution of LED product at present, but reflection brings the reduction of optical efficiency to make the product overall performance can not reach perfect condition.
Summary of the invention
Purpose of the present invention is exactly to provide in order to overcome the defect that above-mentioned prior art exists that a kind of drive part space is large, the full luminous intensity distribution type LED lamp of the wide-angle illumination that can realize standard sources.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of full luminous intensity distribution type 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 described lamp body, described LED lamp also comprises the center ring be located in 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 be located on center ring, described upper light source board and lower light source board lay respectively in illumination cavity and lower illumination cavity, and connection drive circuit.
Described center ring comprises columnar portion and is located at the annulus section on columnar 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 columnar portion.
Described top cover is connected to the upper end of columnar portion, and described fin is located at the lower end of columnar portion.
Described lamp adapter assembly is located at the lower end of columnar portion, comprises lamp holder plastic piece and lamp holder.
Described cell-shell comprises upper cell-shell for sealing upper illumination cavity and 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 present invention is by arranging upper light source board and lower light source board is thrown light on to two parts up and down of LED lamp respectively, can realize the wide-angle illumination, because the columnar portion of center ring runs through whole lamp body, the drive circuit of driving LED can be arranged in this columnar portion, make the space for the configuration driven circuit obviously be 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.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Fig. 1~4, a kind of full luminous intensity distribution type LED lamp, comprise top cover 1, cell-shell, center ring 4, light source assembly, drive circuit 7, fin 8 and lamp adapter assembly.Cell-shell comprises cell-shell 2 and lower cell-shell 6, and light source assembly comprises light source board 3 and lower light source board 5, and lamp adapter assembly comprises for connecting lamp socket, comprises lamp holder plastic piece 9 and lamp holder 10.Top cover 1, cell-shell and lamp adapter assembly connect and compose lamp body, center ring 4 is located in lamp body, the columnar portion 41 that runs through whole lamp body and the annulus section 42 be located on columnar portion 41, consist of, annulus section 42 is divided into upper illumination cavity and lower illumination cavity by whole lamp body, respectively by upper cell-shell 2 and 6 sealings of lower cell-shell.Upper light source board 3 is arranged on the upper surface of annulus section 42, be positioned at illumination cavity, lower light source board 5 is arranged on the lower surface of annulus section 42, be positioned at lower illumination cavity, drive circuit 7 is located in columnar portion 41, connects lower light source board 5, upper light source board 3, luminous for driving it, top cover 1 is connected to the upper end of columnar portion 41 by the mode of clamping, fin 8 is located at the lower end of columnar portion 41.
The optical characteristics of this LED lamp is as shown in Figures 2 and 3: upper light source board 3 and lower light source board 5 can be adopted in two ways and make: 1, LED light source mounts on corresponding wiring board: 2, LED chip directly is encapsulated on the substrate of correspondingly-sized.LED lights rear light and passes through upper cell-shell 2 or 6 direct projections of lower cell-shell respectively and go out, the light source board complementation of two directions realizes the full luminous intensity distribution of LED lamp, for improving the structural member light extraction efficiency, can carry out reflective processing at the inner surface of upper illumination cavity and lower illumination cavity or reflecting part is set.
