Specific embodiment
The present invention is further illustrated in the following with reference to the drawings and specific embodiments.
Embodiment 1
The present embodiment discloses a kind of pass-through type dodging device, as shown in Figure 1, including skeleton 1, being set to 1 inside of skeleton
LED light source 2, the penetrating even light net 4 positioned at the reflection wall 5 on 2 opposite of light source, above light source 2 and positioned at the lower section of light source 2
Hollow out decorative panel 3.Hollow out decorative panel 3 is equipped with the hollow out decorative pattern of several arbitrary shapes, that is, plays a supportive role, and play role in decoration.
In the present embodiment, penetrating even light net 4 is by even 6 knitting forming of chevilled silk, and even 6 section of chevilled silk is cylindrical and regular array.Such as Fig. 2 institute
Show, the periphery reflection angle for even chevilled silk 6 of the light through even light net 4 that LED light source 2 issues increases, can be in the even chevilled silk 6 of the rule
Between do diffusing reflection transmitting.Penetrating even 4 surface of light net is coated with one layer of high molecular nanometer diffusing reflection paint again, and even light characteristic is greatly
By force.Reflection wall 5 is set to 2 opposite of LED light source, and the light that LED light source 2 can be made to issue is reflected back even light net 4, has both improved luminous energy benefit
With rate, but can overcome the disadvantages that even light net 4 apart from LED light source 2 too far caused by light source weaken.In this way, being using a small amount of LED light source
The light on the penetrating even light net 4 of large area can be made to beat, light is shining into soft not dazzling after human eye again, has both saved lamps and lanterns manufacture
Cost reduces lamp power again, and energy-saving effect is significant.Along with control LED discoloration, lamps and lanterns can show magnificent mansion
Effect.And during the day, the permeability of penetrating even light net 4 solves large scale lamps and lanterns to the sense of depression and sense of heaviness of people, can also
To solve the problem of because the too big windage of lamps and lanterns area is greatly vulnerable to destruction.
In the present embodiment, the light that light source 2 issues injects penetrating even light net 4 after reflecting directly or through reflection wall 5, passes through
Light emission after the even light of penetrating even light net 4 carries out diffusing reflection to incident light to illumination region, penetrating even light net 4 and reflection wall 5, overflows
Incident ray, reflection light, the normal vector of reflecting surface meet formula 1:
N indicates refractive index, and n=1,Indicate the direction vector of diffusing reflection face emergent ray,It is diffusing reflection face incident ray
Direction vector,It is the normal vector in diffusing reflection face；The light distribution in diffusing reflection face meets formula 2,
E (x, y, z) indicates the light distribution in diffusing reflection face, x, y, and z respectively indicates the three-dimensional of diffusing reflection face light distribution space and sits
Mark, m is the half light intensity angle θ with diffusing reflection face1/2Related numerical value, is given byI6Represent diffusing reflection
The diffusing reflection light intensity in face, i represent x-axis component, and j represents y-axis component, and M, N are used to indicate that the row and column of diffusing reflection face array, d to be
The distance between adjacent two diffusing reflection face.
As shown in figure 5, when penetrating even light net 4 carries out diffusing reflection, if the O on optical axis is located in LED light source light-emitting surface
The heart, light-emitting surface of the OZ perpendicular to LED light source, lightIt is emitted by LED light source light-emitting surface center, the cylinder through the even light net of permeability
After wire surface B point reflection, emergent ray is formed
The coordinate of the B point is (x, y, z), vector are as follows:
The unit vector of incident ray OBAre as follows:
After the reflection of B point, the unit vector of emergent rayAre as follows:
The normal vector of B pointAre as follows:
Incident ray, reflection light, the normal vector of even chevilled silk 6 meet formula 1, and light distribution meets formula 2, when even light
When silk 6 is suitable for formula 2, M, N indicate that the row and column of even chevilled silk array, d are the distance between adjacent two even chevilled silk.
Reflection wall 5 is also applied for formula 1 and formula 2, since reflection wall 5 is equivalent to a big diffusing reflection light-emitting surface, because
This is when reflection wall 5 is applicable in formula 2, M=1, N=1, d=0.
In the present embodiment, penetrating even light net 4 can also be formed by punching plates, and when for punching plates, even chevilled silk 6 is real
Partition of the border between punching and hole.
In the present embodiment, the LED light source 2 can be point light source, light bar, fluorescent tube, be also possible to monochromatic lamp bead or complete
Coloured silk discoloration lamp bead.
The skeleton 1 can be pipe or plate, plays installation, connects each components.
As shown in Figure 3,4, for this light emitting device to be applied to schematic diagram when Landscape Lamp, landscape is mounted on by skeleton 1
On lamp lamp body, what LED light source issued is pointed into illumination space after the reflection of reflection wall 5 and even light net 4.This Landscape Lamp uses few
The light that the LED light source of amount can make the penetrating even light of large area online is beaten, and light both saved again according to soft not dazzling after newborn human eye
About lamps and lanterns manufacturing cost reduces lamp power again, and energy-saving effect is significant.During the day, the permeability of even light net solves greatly
Size lamps and lanterns also can solve to the sense of depression and sense of heaviness of people because lamps and lanterns area is too big, windage greatly vulnerable to destroy the problem of.
Described above is only basic principle and preferred embodiment of the invention, and those skilled in the art do according to the present invention
Improvement and replacement out, belong to the scope of protection of the present invention.
