The following describes the optical parameter optimization and design process of TIR lens of reading lamp
First, general theory:
the lens is widely used for LED illumination, and has the advantages of high luminous efficiency eta of 85 percent and simple and convenient installation. Is convenient for being used in various lamps.
The TIR lens combines the characteristics of a convex lens and a reflecting cup, and makes the light entering the lens totally reflected in the lens by utilizing the total reflection principle. The TIR lens has the advantages of high light energy utilization rate, less light loss, small light collecting system and good uniformity.
The idea of the invention is to use TIR lenses in reading lamps using secondary optics. The requirements of a specific light class, specified illuminance and uniformity are met by designing and optimizing the structural parameters of the TIR lens.
Secondly, the design concept is as follows:
the design basis of the TIR lens is a preset light distribution requirement, the preset light distribution requirement is obtained by redistributing the light distribution of the light source, and the form of the TIR lens can be preset according to the requirement of an illuminated surface or the requirement of a user. The preset light distribution requirement is to determine the maximum light intensity value, the beam angle, the total luminous flux, the uniformity and other numerical values besides the display light distribution form.
The key of the TIR lens lies in the parameter design of the exit interface, the total reflection surface and the first transmission surface of the lens.
1. Efficiency problem of the exit interface 21
The efficiency of the first interface is important, which determines the light flux utilization of the entire lens. As shown in fig. 3.
The angle β is a half-angle distribution of the light passing through the first interface of the light source 20, and the light is refracted twice on the lens and is a part of light with a smaller refraction number.
When the angle β increases, the luminous flux of the light source 20 in this portion increases, the light flux loss is small, but the light rays will shift outward, and useless light flux will be generated.
When the angle β is decreased, the luminous flux of the light source 20 passing through this portion is decreased, and the efficiency is decreased.
2. Obtaining total reflection surfaces
The total reflection surface is a main part for distributing the light flux of the LED, and whether the designed lens meets the preset light distribution requirement or not mainly depends on whether the design of the total reflection surface is reasonable or not.
Fig. 4 shows the formation process of one light ray in the total reflection surface.
In the process of designing the lens, the design idea is as follows: according to the principle that the light path is reversible in the refraction and reflection phenomena of light, the trend of the light path is reversely calculated from a preset light emergent angle C so as to determine the shape (B curve) of the total reflection surface of the lens.
Thirdly, designing:
1. design of emergent interface
The form of the lens exit surface generally includes a plane surface, a quadratic surface, etc., and fig. 5 and 6 are common forms of the lens exit surface.
As shown in fig. 5 and 6, by optimally designing the exit interface of the lens, the loss of the light flux of the light source 20 passing through this part is reasonably controlled, the light emitting efficiency of the LED is improved to the maximum, and the light intensity value of the lens is the same as the preset light distribution requirement.
2. Design of total reflection free-form surface
The total reflection free-form surface is the main part for distributing the light flux of the LED, especially in a 60-90-degree annular band of the LED, although the light intensity value is not high, the light flux is large, and the free-form surface needs to be reasonably designed to fully utilize the light flux.
The design of the free-form surface is the same as the principle of 'obtaining a total reflection surface' in the above, and the shape of the free-form surface is reversely calculated only according to the principle that light is reversible in refraction and reflection.
3. Design of the first transmission surface 22
The first transmissive surface 22 is one of the means for reasonably distributing the light intensity at the center of the LED, and generally has two forms, i.e., a planar form and a convex form, as shown in fig. 7 and 8.
In the planar lens, although the angle of refraction is smaller than the angle of incidence after the light enters the planar surface, the angle of refraction gradually increases as the angle of light emitted from the light source 20 gradually increases, and the light is shifted outward and has a black spot at the center of the light.
After the convex lens is adopted, the light rays can reduce the offset of the refracted light rays along with the difference of the normal directions, the central light intensity is increased, and the central black spot cannot be generated.
Fourthly, optimizing a design result:
the utility model discloses the target of TIR lens does: the LED irradiation area is as follows: 30CMx30CM linear regions; the light intensity of the irradiation surface is 350Lx, and the uniformity is less than 3.0.
According to the principle, the total reflection part is designed according to the edge light refraction principle and the Snell's law, and the contour line of the total reflection part is obtained by adopting the numerical integration iterative method for calculation; designing the transmission part by a trial and error method to obtain a contour line of the transmission part; and integrating the total reflection part and the transmission part into a new arch lens by combining the contour line and applying UG 3D modeling. The parameters of the above lens were optimized using LightTools. The final TIR lens was obtained with the structural dimensions: the dimensions were 13mm by 7.5 mm.
Simulation and practice results show that: the utility model discloses a TIR lens, after matching the LED light source, optical efficiency is higher than 85%, and half light intensity angle reaches 9 x 135, can realize even illumination in the linear region of 30CMx30CM, and its homogeneity is < ═ 3.0; the light intensity on the irradiation surface is > -350 Lx. Finally, the project requirements are met. The final optical result is shown in fig. 9 and fig. 10, the outer diameter of the exit interface of the left lens is phi 13mm, the height of the lens is 8.0mm, the top radius of the first transmission surface is 4.5mm, the radius of the lens root circle is 7mm, the diameter of the cylindrical surface of the first transmission surface side is phi 5mm, the curvature radius of the total reflection surface is 6.5mm, and the parameters of the right lens and the left lens are the same.
