Virtual Product Development

To accelerate the virtual product development of using optical simulation software, the Robust Design Optimization approach is very promising. Optical designs can be explored thoroughly by means of sensitivity analysis. This includes the identification of relevant input parameters and the modelling of inputs vs. outputs to understand their dependencies and interactions. Furthermore, the intelligent definition of objective functions for an efficient subsequent optimization is of high importance for multi-objective optimization tasks. To find the best trade-off between two or more merit functions, a Pareto optimization is the best choice. As a result, not only one design, but a front of best designs is obtained and the most appropriate design can be selected by the decision maker. Additionally, the best trade-off between output variation of the robustness (tolerance) and optimization targets can be found to secure the manufacturability of the optical design by several advanced approaches. The benefit of this Robust Design Optimization approach will be demonstrated.

This paper presents a new kind of light emitting diode(LED) secondary light distribution lens which adopts the type of Fresnel lens surface. The research purpose of this paper is to improve the LED heat dissipation efficiency of the secondary light distribution lens and the light efficiency, so as to prolong the service life of the LED. In this paper, we use the numerical method for solving the partial differential equation to establish a freeform surface lens which could produce uniform illumination, then the innovative method of combine the Fresnel lens structure with freeform surface lens was proposed. The design of freeform surface Fresnel lens allows dramatically cut the thickness of the lens (as well as the weight and volume) , it can solve the problem of difficulty in heat dissipation. By comparing the ray tracing simulation results of original freeform surface lens and freeform surface Fresnel lens in optical simulation software, experiments show that the latter not only shows the same degree of illumination uniformity, but also greatly reduced the thickness of the lens.

Abstract To reduce the efficiency reduction caused by non-uniformity of illumination, a dense-array module with non-uniform sizing of photovoltaic (PV) cells is proposed for dish-type concentrating PV systems. The non-uniform-sized dense-array module has been designed and analyzed theoretically at the ideal irradiance of Gaussian distribution, which consists of 48 silicone solar cells. Using the ZEMAX optical simulation software, the realistic distribution of the Gaussian-like facula on the PV module has been modelled in a dish-type concentrator system. The experiments are done under the conditions of different alignments to imitate the different two-axis tracking accuracy with or without a homogenizer. Besides, the performances of dense-array modules with the classical uniform-sized and the proposed non-uniform-sized PV cells are analyzed under various illumination distributions using ZEMAX, respectively. Results show that when the deviation angle of tracking is 0, 0.02, 0.2, the photoelectric conversion efficiency and output power of the proposed non-uniform size dense-array module considerably exceeds the traditional uniform size module. Furthermore, when the tracking deviation angle is no more than 0.02°, it is a very definite possibility that the dish-type concentrator system with non-uniform-sized dense-array module need not a homogenizer as a secondary optical element, which may hence simplify the system structure.

This paper proposes an epoxy-based anti-reflective micron structure layer for solar cell modules. A Solidworks software is used to design the micro-structure layers with different size and shapes (inverted pyramid and micro-lens). Then, An optical simulation software, Tracepro, is used to simulate the anti-reflection efficiency under the standard lighting source of AM1.5G. The difference between the flat layer and micro-structured layer has been analyzed to obtain the best micro-structure layer for solar cell modules. From the simulated results, the inverted pyramid textured layer that each pyramid’s width is 10μm and height is 5μm can improve the flux increment rate up to 13% compared with the flat layer at normal incidence. However, the best efficiency for micro-lens structure layer increases about 10% with radius of 25μm and height of 18.75μm and 25μm at 15o incidence. In addition, the thinner the Epoxy layer is, the better the anti-reflection efficiency is. Therefore, the proposed Epoxy-based micro-structure can improve the solar module for obtaining higher efficiency and best qualities.

The luminous properties of red, green, and yellow phosphors with a blue LED are evaluated and a corresponding optical model is constructed using the optical simulation software LightTools®. According to the phosphor particle model, the desired chromaticity coordinate of the multicomponent light which is excited by a blue LED can be achieved by modifying the weight concentration of the phosphors. A comparison of the four types of LED package modules tested shows that the yellow phosphor encapsulated with a semispherical module takes up a lesser percentage of the total weight percentage of a constructed white light with a correlated color temperature of around 4000 K. The simulation and experimental results provide a cross-reference for better packaging and encapsulating designs for lumen improvement.

An optical system model for the identification of Carbon-Hydrogen stretching using spectroscopy is demonstrated and applied to the experiment setup. The optical simulation is achieved using simulation software and performed in a two-mirror system. The optical setup covers a wavelength range of 600 nm to 1200 nm which is a new study based on carbon-hydrogen stretch and test with samples from the alkene group. Significant results of the Carbon-Hydrogen stretch from the alkene group at 1149 nm are detected in Dichloromethane and ethanol. This observation is recorded in real-time and applied in a fast diagnostic system. The isosbestic point of water is measured at 970 nm and useful for our system spectral calibration. The result also shows the ability to quantify the chemical bond of a sample based on two peaks of absorption due to the C-H stretching. This gives a better opportunity for Chemometrics to perform accurately.
