Accompanying drawing 2 is the utility model light path effect diagram.
Embodiment
For feature of the present utility model, technological means and the specific purposes reached, function can be further appreciated that, below
The utility model is described in further detail with embodiment with reference to accompanying drawing.
As shown in figure 1 and 2, the utility model discloses a kind of LCDs LED lens, including lens body,
Lens body, which has, into light bottom surface, light extraction top surface 2 and light extraction side 3, enters light bottom surface provided with the incident chamber for being used to install LED light source
6, light extraction side 2 is reflecting surface, and the incident chamber 6 is made up of incident inclined side 51 and incident arc top surface 52, light extraction top surface 2
The central concave of lens body forms inverted cone-shaped structure, and light extraction top surface 2 is by going out 21 groups of anaclasis top surface 22 and light extraction reflective top surface
Into going out the bottom that anaclasis top surface 22 is located at light extraction top surface, light extraction reflective top surface is located at the top of light extraction top surface, enters light bottom surface and sets
There is total reflection inclined plane 4, the side of total reflection inclined plane 4 is connected with light extraction side lower, side is connected with entering light bottom surface.It will go out
Spire face is set to by light extraction reflective top surface and goes out the configuration state that anaclasis top surface forms, and a part of light is mapped to out anaclasis top
Face occurs refraction and projected directly up, and a part of light is mapped to be mapped to light extraction side after light extraction reflective top surface reflects and penetrate again
Go out.
The light extraction side 3 by upper light extraction face directly 31 and lower light extraction curved surface 32 form, the light made reflect away after more
Uniformly.
Institute's light extraction reflective top surface 2 is additionally provided with least two raised arc-shaped curved surfaces 1, is spaced between two neighboring arc-shaped curved surface
Set.Using the arc-shaped curved surface, it can make light that birefringence occur, so as to form the superposition of the light of different directions, make light
Line irradiation is brighter and uniform.
The size of the two neighboring arc-shaped curved surface differs.Difference, satisfaction are multi-party as far as possible for the refractive direction of the light made
To refraction.
Attaching has mounting leg 7 on the incident bottom surface, is easy to assemble.
The light extraction top surface and incident chamber are centrally located on same axis, make the light of injection more uniform.
The light extraction top surface and light extraction side are equipped with spark lines, and the light for projecting lenticular body is softer.
As shown in Figure 2, light source is installed in incident cavity region, the light that light source projects is after incident chamber surface refraction, and one
Some light is mapped to out the generation refraction of anaclasis top surface and projected directly up；A part of light is mapped to light extraction reflective top surface and occurred instead
The injection of light extraction side is mapped to after penetrating again；A part of light is mapped to after light extraction reflective top surface reflects and is mapped to total reflection inclined plane
On, reflex to after light extraction side reflects and outwards project again.
It should be noted that these are only preferred embodiment of the present utility model, it is new to be not limited to this practicality
Type, although the utility model is described in detail with reference to embodiment, for those skilled in the art, it is still
Technical scheme described in previous embodiment can be modified, or equivalent substitution is carried out to which part technical characteristic,
