  • Abstract This text is mainly the goal to do a series of discussions to the design and verification of asymmetry type LED that is applied to the traffic signal. First of all, introduce the normal kinds of specifications of the traffic signal and luminous intensity demand, then direct against the analysis of the advantages and shortcomings  of LED traffic signal classification in the optics design in the world at present. And then, we can find out LED chip light optical model according to the comparison between measurement and optical simulation, utilize this give out light optics model of chip to design LED of asymmetry type by computer simulation, and then make the LED mold and package asymmetry type LED. In order to verify the exactness of optics simulation, we measure the optical data of asymmetry type LED to compare with the result of optics simulation. Later, carry on the normal verification of traffic signal specification, in order to confirm the practicability of this asymmetry type LED. Finally, carry on the packaging variation analysis of asymmetry type LED in order to understand the effect upon optics characteristic. According to these results, we can improve the packaging error to reach the goal of packaging uniformity. 
    In a word, according to the special demand of light distribution of traffic signal specification, we can find out the asymmetry type LED to satisfy the special demand of traffic signal by way of optics simulation, follow specific procedure. Later, we can make a series of actual experiments to compare with result of optics simulation in order to confirm the correctness of the LED. Finally, we product the LED traffic signal and measure it by specification of traffic signal in order to verify the practicability. Such as the asymmetry type LED can lower the costs of traffic signal and reach the goal to save the energy.
