As the price of light-emitting diodes (LEDs) is getting lower and lower, the competition in the LED lighting market is becoming more and more fierce. Simulation to verify the feasibility of products has become an important weapon for related companies to defeat the enemy.
General manager of Luming Technology Zhuang Shiren said that because the LED product design has to undergo many tests and verification, if the optical simulation and heat dissipation simulation are not done, the product will have quality defects after mass production. In order to solve this problem, the use of dedicated simulation software and three-dimensional (3D) models to accurately simulate and analyze LEDs has become an indispensable link in the development of LED lamps to ensure the quality and reliability of future LED products .
Zhuang Shiren further pointed out that the most important purpose of optical and thermal simulation is to accelerate the time to market of the product, but also to avoid the cost burden caused by repeated production of a large number of model machines due to incorrect simulation results. The simulation process and effectiveness will affect whether the product can be confirmed in the shortest time, and then affect the time to market, so it is very important to efficiently carry out product optical simulation and thermal simulation.
The correct optical simulation process should first create a 3D model, then create a light source, then create an observation surface, and then analyze it through major simulation software such as Trace Pro, Light Tool, etc. If it encounters a more complicated optical structure, it may be Need to use auxiliary software such as ZEMAX, Code V to observe the results, if the test results are feasible, then output the results; if the test results cannot be optimized, then return to the previous process, re-calibration and simulation analysis.
After the optimized results of the optical simulation are output, the thermal simulation can be started. Zhuang Shiren said that conducting heat dissipation simulation can reduce unnecessary waste during proofing, and the error between the data obtained through the analysis software and the actual temperature measurement can be within 5 ° C, allowing R & D personnel to master the product parameters first. After the above simulation steps, the product reliability can be more ensured.
In addition, in order to perform efficient optical simulation and heat dissipation simulation, in addition to being quite familiar with the simulation software, the operating R & D personnel must also have rich experience in order to quickly check which link is wrong. However, not every manufacturer can find excellent simulation verification talents. Therefore, in order to copy shortcuts, save personnel and time costs, some LED manufacturers today directly copy the exterior design of major international manufacturers, and ignore the importance of optical and thermal simulation. It was not until the mass production of the product that it was found that it was far from the quality of the big factory, resulting in damage to the goodwill.
