Problems solved by technology

However, this approach not only makes the overall structure more complicated, but is not conducive to the miniaturization of the device, but also causes a large energy loss because the light must pass through more layers of media conversion before reaching the surface of the target illuminated object.

Abstract

The invention discloses a primary optical free-form surface structure construction method, including the steps of acquiring an image corresponding to an objective light shape; obtaining a preliminaryobjective function; acquiring a preliminary free-form surface stereomodel; importing the preliminary free-form surface stereomodel into beam tracking software to simulate a preliminary result light shape; acquiring a preliminary result function corresponding to the preliminary result light shape; producing a modified objective function according to the comparison between the preliminary result function and the preliminary objective function; acquiring a modified free-form surface stereomodel; importing the modified free-form surface stereomodel into the beam tracking software to simulate a modified result light shape; acquiring a modified result function; and comparing the modified result function with the preliminary objective function to obtain a difference value, and constructing a primary optical free-form surface structure according to the modified free-form surface stereomodel when the difference value is less than a preset threshold value. The construction method can be used toobtain the best modified free-form surface stereomodel and build the primary optical free-form surface structure capable of generating the objective light shape as desired.

Description

technical field [0001] The invention relates to a manufacturing method of an optical structure, in particular to a manufacturing method of a primary optical free-form surface structure. Background technique [0002] Light-emitting diodes (LEDs for short) generally require two optical structure designs before they are actually applied as components of lighting equipment. First of all, when the LED is made into the required optoelectronic components through the integrated circuit (IC) packaging technology, the first optical structure design must be carried out to solve the problem of the LED's light angle, light intensity, luminous flux, and light intensity. Strong distribution and the range and distribution of color temperature. Generally, after the light emitted by a high-power LED passes through the primary optical structure lens, its luminous angle is about 120 degrees. On this basis, the secondary optical structure design is carried out, the purpose of which is to reprod...
