First light distribution portion 231 includes first plane of incidence 2311 (a side groove face of trapezoidal fluting), the first reflecting surface
2312 (sides of lens 23) and the first exit facet 2313 (planar section of the top surface side of lens 23).First reflecting surface
2312 meet total reflection condition, that is, the light for being mapped to the first reflecting surface 2312 is propagated from optically denser medium to optically thinner medium, the same to time
The incidence angle of line is more than critical angle.Specifically, in the present embodiment, first plane of incidence 2311 by by the side of close to sources 21 to separate
The side of light source 21 moves closer to center line, and the differential seat angle between first plane of incidence 2311 and center line is 0 °~10 °, i.e., first enters
The angle e penetrated between face 2311 and mounting surface (i.e. the vertical line of the center line of the light angle of emergence of light source 21) is respectively 90 °~100 °.
First reflecting surface 2312 to the side far from light source 21 by the side of close to sources 21 by being gradually distance from center line, and the first reflecting surface
Differential seat angle between 2312 and center line is 10 °~20 °, i.e. angle g between the first reflecting surface 2312 and mounting surface is respectively 70 °
~80 °.Therefore, the light that light source 21 is sent out is refracted into the first light distribution portion 231 and is incident upon by first plane of incidence 2311
First reflecting surface 2312, since the first reflecting surface 2312 meets total reflection condition, it is incident upon the light of the first reflecting surface 2312
Total reflection occurs and returns to inside the first light distribution portion 231, is emitted after the refraction using the first exit facet 2313, is irradiated to light extraction
The first area A1 at face most edge.
Second light distribution portion 232 includes second plane of incidence 2321 (another side groove face of trapezoidal fluting), the second reflecting surface
2322 (another side of lens 23) and the second exit facet 2323 (planar section of the top surface other side of lens 23).Second enters
It penetrates face 2321 and meets total reflection condition, that is, the light for being mapped to the second reflecting surface 2321 is propagated from optically denser medium to optically thinner medium, together
When light incidence angle be more than critical angle.Specifically, in the present embodiment, second plane of incidence 2321 by by the side of close to sources 21 extremely
Side far from light source 21 moves closer to center line, and the differential seat angle between second plane of incidence 2321 and center line is respectively 0 °~10 °,
That is the angle f between second plane of incidence and mounting surface (i.e. the vertical line of the center line of the light angle of emergence of light source 21) is respectively 80 °~
90°.Second reflecting surface 2322 to the side far from light source 21 by the side of close to sources 21 by being gradually distance from center line, and the second reflection
Differential seat angle between face 2322 and center line is respectively 10 °~20 °, i.e., h points of the angle between the second reflecting surface 2322 and mounting surface
It Wei not be 100 °~110 °.Therefore, the light that light source 21 is sent out is refracted by second plane of incidence 2321 to the second light distribution portion
In 232 and it is incident upon the second reflecting surface 2322, since the second reflecting surface 2322 meets total reflection condition, it is incident upon the second reflection
The light in face 2322 occurs total reflection and returns to inside the second light distribution portion 232, goes out after the refraction using the second exit facet 2323
It penetrates, the second area A2 being irradiated between light-emitting surface most margin and center part.
Third light distribution portion 233 includes the third plane of incidence 2331 (the top surface groove face of trapezoidal fluting) and third exit facet 2332
(the convex surface section of the top surface of lens 23).The third plane of incidence 2331 and third exit facet 2332 are combined into approximate convex lens type, rise
Effect of light is collapsed to convergence.Angle becomes smaller after the light that light source 21 is sent out is reflected by the third plane of incidence 2331, travels to third
The light beam that angle very little is formed at exit facet 2332, then after being collapsed via the convergence of third exit facet 2332 reflects, and is mapped to out
The third region A3 of smooth surface central part.
Certain the utility model is not limited system, and lens face type can also be arranged to other forms, so that first matches
Light portion, the second light distribution portion and third light distribution portion are respectively used to the light that light source is sent out being individually directed to the firstth area of light-emitting surface
Domain, second area and third region.
In addition, in the present embodiment, width of the lens in the vertical line direction of the center line for the light angle of emergence for being parallel to light source 21
It spends maximum value and is more than 20mm, in order to which optical texture designs.
First light distribution portion 231, the second light distribution portion 232 and third light distribution portion 233 realize each region of light-emitting surface (first respectively
Region A1, second area A2, third region A3) light extraction so that panel light reaches the optical effect of uniformly light-emitting.Simultaneously
For the illumination effect of more uniform panel light, the first reflecting surface of the present embodiment 2312 is in micro-structure zigzag, destroys total reflection
Condition makes the light traveled on first plane of incidence 2311 have small part light leakage, this part light of leakage to be responsible for illuminating
Smooth surface center part area.
Certainly, the utility model is not limited system, and in other embodiments, the first reflecting surface 2312 can not also be formed
Micro-structure zigzag or the first reflecting surface 2312 can also form erosion line so that 2312 surface roughening of the first reflecting surface is broken
Bad total reflection condition, so that the light traveled on first plane of incidence 2311 has small part light leakage.
Meanwhile in the present embodiment, light that light source 21 is sent out is mixed light, wherein the light component in yellow band compared with
It is more, and lens 23 can play the role of prism to a certain extent, the yellow component in light that light source 21 is sent out can be separated,
Lead to be easy that there are yellow light spots in panel light light extraction.Therefore, each surface of the present embodiment lens 23 may be provided with more slight erosion
Line increases light mixing effect, prevents macula lutea from being formed, meet light extraction colour consistency to break up light.
The outer surface of mask 3 is light-emitting surface, and then blocks chassis 1.3 material of mask can be PC be alternatively PMMA or
PS has certain mist degree to mixed light.The present embodiment lamps and lanterns single side light extraction, there are one outer surface (i.e. light extractions for 3 tools of mask
Face), and mask 3 is opposite with the bottom wall 11 on chassis 1, the side wall 12 on chassis 1 connects mask 3 and bottom wall 11.In other embodiment, lamp
Tool or multi-panel light extraction, at this point, mask has multiple light-emitting surfaces, may include top surface and side, chassis only has at this time
There is similar flat bottom wall, bottom wall is opposite with top surface, and side connects top surface and chassis.
Frame 4 is used to mask 3 being fixed to chassis 1, and then assembles and form panel light.
