Embodiment
[0036] A novel LED optical design feedback optimization method: comprising the following steps:
[0037] 1. Mesh the free-form surface of the lens and the target surface, and adopt image 3 The division method shown divides the free-form surface and the target surface into grids, and establishes the corresponding relationship of the corresponding grid points (φ i ,θ j )——(x i ,y j ), where the angle φ is the angle between the light direction and the normal direction of the LED chip plane (ie, the positive direction of the Z axis), and the angle θ is the angle between the projection of the light on the XOY plane and the positive direction of the X axis.
[0038] 2. Carry out iterative solution of the surface data points according to the established corresponding relationship, import the data points into the 3D drawing software SolidWorks to obtain the initial lens model, and simulate and analyze the built model in TracePro, the simulation results are as follows Figure 5 (a...

The invention relates to the technical field of LED (Light Emitting Diode) lighting, in particular to a novel LED optical design feedback optimizing method for optimizing a free curved plane of an LED lens. The method comprises the following steps: 1) carrying out mesh dividing on a free curved plane and a target plane of an established lens model; 2) figuring out illuminance distribution of the target plane; 3) introducing an arithmetic progression and adjusting the size of meshes of the target plane or the meshes of the free curved plane according to calculated actual illuminance; and 4) adjusting the free curved plane of the LED lens. According to the invention, feedback factors distributed in the form of the arithmetic progression are introduced to optimize the design according to a characteristic that the illuminance is continuously affected by deviations; the optimizing method is simple in operation; and the workload of the design process is greatly reduced.
Description
technical field [0001] The invention relates to the technical field of LED lighting, in particular to a novel LED optical design feedback optimization method optimized for free-form surfaces of LED lenses. Background technique [0002] Compared with traditional lighting sources, LED has the advantages of energy saving, environmental protection, long service life, and fast response. High-power LED lighting technology has attracted widespread attention from the light source industry at home and abroad, and has become a high-tech with development prospects and influence. Products, the development, research and production of LED lighting products have become a sunrise industry with very attractive development prospects. Since the light emitted by LEDs is similar to the Lambertian type, which is quite different from traditional light sources, it cannot be directly used in existing lighting systems. Therefore, in order to better use LED as a lighting source, it is particularly ur...
