Background technology
LED, i.e. light emitting diode, it has characteristics such as efficient, energy-conservation, long-lived, small and exquisite, becomes main force's light source of illumination market of new generation gradually.LED uses the most extensive as lighting source, it mainly is that led light source is electrically connected the light source board surface, and connects uses such as driving power and cooperation radiator structure.Yet the LED lighting source of prior art, its light source board are that single face is luminous mostly, promptly in the front of light source board led light source are installed, and this mounting means lighting angle is limited, are difficult to satisfy the use needs.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of LED ray structure is provided, and realizes the extensive angle luminous intensity distribution.
The technical scheme of the utility model is: a kind of LED ray structure comprises first led light source, second led light source, light source board and reflection platform; First led light source is installed on the front of light source board, and second led light source is installed on the reverse side of light source board; The surface of reflection platform has the reflecting layer, this reflection platform and light source board reverse side Joint.
The ratio of said first led light source number and the said second led light source number is 1: 5.
Said reflection platform is conical column structure, and the wall border of this conical column structure has said reflecting layer, end that this conical column structure diameter is less and said light source board Joint.
Said light source board is structure ringwise, and said first led light source is evenly spaced apart along the positive border of this loop configuration, and said second led light source is evenly spaced apart along the reverse side border of this loop configuration.
One end of said reflection platform is intercalated in the inner ring of said loop configuration.
Also comprise a ball bubble-cap, said light source board and said reflection platform are coated on respectively in this ball bubble-cap
The beneficial effect of the utility model is; Because its front at light source board is equipped with first led light source; Reverse side at light source board is equipped with second led light source; And install the reflection platform that a surface has reflex additional at the reverse side of light source board; Make that light that second led light source of this light source board reverse side sent can be through the surface reflection of reflection platform, and the light that combines the first positive led light source of light source board to send realizes the extensive angle luminous intensity distribution, thereby overcome the limited deficiency of LED ray structure luminous intensity distribution angle of prior art.

The specific embodiment
Embodiment sees also Fig. 1-shown in Figure 3, and a kind of LED ray structure of the utility model comprises first led light source 1, second led light source 3, light source board 2 and reflection platform 4.First led light source 1 and second led light source 3 are respectively paster LED light source (can certainly adopt the led light source with two pins), and wherein, first led light source 1 is installed on the front of light source board 2, and second led light source 3 is installed on the reverse side of light source board 2; The surface of reflection platform 4 has the reflecting layer, is used for reflection ray, and this reflection platform 4 is in the reverse side and light source board 2 Joints of light source board 2.
As a kind of preferred, the ratio of said first led light source number and the said second led light source number is 1: 5.
As a kind of preferred, reflection platform 4 is conical column structure, and the wall border of this conical column structure is provided with above-mentioned reflecting layer, end that this conical column structure diameter is less and light source board 2 Joints.Reflection platform 4 also can have other structure, like four rib structures etc.
As a kind of preferred, light source board 2 is structure ringwise, and said first led light source 1 is evenly spaced apart along the positive border of this loop configuration, and said second led light source 3 is evenly spaced apart along the reverse side border of this loop configuration.The less end of the diameter of said reflection platform 4 is intercalated in the inner ring of this loop configuration, realizes both relative fixed.Light source board 2 also can adopt circular laminated structure, perhaps square structure etc.
As a kind of preferred, the utility model also comprises a ball bubble-cap 5, and said light source board 2 is coated on respectively in this ball bubble-cap 5 with said reflection platform 4.
A kind of LED ray structure of the utility model, the reflection platform is installed up, and after energising, detects its distribution curve flux such as Fig. 3, shown in Figure 4 with distribution photometer.Wherein, Fig. 3 is the distribution curve flux figure of the utility model under polar coordinates, circumferentially representes angle, radially representes luminous intensity (cd); Article four, curve is represented respectively: measured distribution curve flux when curve a vertically installs (reflection platform up) for this LED ray structure; Curve b turns over 45 measured distribution curve fluxs when spending for the relative vertical line of this LED ray structure; Curve c turns over 90 measured distribution curve fluxs when spending for the relative vertical line of this LED ray structure, and curve d turns over 135 measured distribution curve fluxs when spending for the relative vertical line of this LED ray structure.Four curves of Fig. 3 form closed curve respectively in 360 degree scopes, promptly in 360 degree scopes, all can detect the light of this LED ray structure.Fig. 4 is the distribution curve flux figure of the utility model under rectangular coordinate system, and it laterally representes angle, vertically representes luminous intensity (cd); It has four curve a, b, c, d equally, the vertical installation of corresponding LED ray structure respectively (the reflection platform up), deflection 45 degree, deflection 90, deflection 135 degree one of four states.Four curves of Fig. 4 are covered with the scope of-180～180 degree respectively, promptly in the scope of-180～180 degree, all can detect the light of this LED ray structure.It is thus clear that behind the employing said structure, the utility model has been realized 360 degree luminous intensity distributions, has overcome the limited deficiency of LED ray structure luminous intensity distribution angle of prior art.
