LED design accelerate the development of LED optical / thermal simulation is essential

With the light emitting diode (LED) is more and more low price, LED lighting market has become increasingly fierce competition, in order to accelerate the LED product process and reduce the overall cost of development, in the official opening of pre production, to verify the feasibility of the product by using optical simulation and thermal simulation, has become an important weapon to vanquish the related industry.

Wang Ming, general manager of green science and technology, said that because of LED's product design to go through a lot of test verification, if not done optical simulation and thermal simulation, will lead to quality defects in the product after mass production. In order to solve this problem, the use of simulation software for three dimensional collocation (3D) model for LED accurate simulation analysis and verification, has become an important part of LED lighting development is not necessary, to ensure that future LED product quality and reliability.

Zhuang Shiren further pointed out that simulation and optical radiation, the largest in addition to accelerate product launch process, but also can avoid the error simulation results, and the production of a large number of repeated derivative model caused by the burden of the cost of. The process and effectiveness of the simulation will affect whether the product can be recognized in the shortest possible time, and thus affect the timing of the market, it is essential for efficient optical simulation and Simulation of heat dissipation.

The correct simulation of optical flow should first establish the 3D model, then establish the source, followed by the establishment of a plane is analyzed through observation, such as Trace Pro, Light Tool and other major simulation software, when the optical structure is more complicated, you may need to use such as ZEMAX, Code V and other auxiliary software to observe the results. If the test result is feasible, then the output results; if the test result can not be the best, then returned to one step process, re calibration and simulation analysis.

The simulation results of the optical simulation output, you can begin to heat simulation. Zhuang Shiren said that the waste heat can reduce unnecessary simulation proofing, and through the data analysis software with the actual temperature measurement error is within 5 DEG C, so that researchers can first grasp the product parameters. Through the steps of the simulation, we can ensure the reliability of the product.

In addition to the optical simulation and the heat efficiency of the simulation, in addition to the familiar with simulation software, the operation of R & D personnel must have the rich experience, can quickly check out which part of the error. However, not all manufacturers are able to find the best simulation talent, therefore, some manufacturers in order to LED personnel and time shortcut, save cost, direct copy design international manufacturers, and ignore the importance of optical and thermal simulation, until mass production, found far from manufacturers of quality, lead goodwill impairment.
