LED minelamp is a new type of explosion-proof minelamp for the miners working underground, use of advanced LED cold light source, and charging by thelithium-ion battery. The lamp can be used by coal miners in underground-lighting, and it can also be used for rescue and relief or other special occasions,with advantages as safe, reliable, easy maintenance, energy saving. etc. ZEMAX is capable of conventional optical simulation and analysis software, it is widely used in LED optical design. This application optical simulation software, LED lamp secondary optical design and optimization. LED lamp structure from the measured view, as the initial structure of the collimator system to obtain optimal reflective glass collimating structure through non-sequential ray chase, making spot uniformity, thereby improving the luminous efficiency of miner's lamp. In addition, this paper presents the design of LED lamp model, modeling, testing, optimization and modeling and testing for problems encountered and solutions related analysis and discussion.
