The performance of the energy-saving lamp in the market has some disadvantages generally,such as low light efficiency,uneven illumintation and high-glare lighting.For this point,a high uniform and low glare LED eye protection lamp is designed.This design joined the aspheric reflector cup lampshade to collect a large angle of light emitted by the LED light source,which raised the light energy utilization and improved glare.This design added the light distribution lens to eliminate the center bright spots which exist in receiving plane and solve the illumination problem.Finally,the entity modeling was carried out by ProE 3D and imported into the TracePro light simulation software.The simulative analysis results show that the design of this LED lamp can realise low glare and can be more uniform illumination within the receiving plane,which with working distance of 450 mm and diameter of 700 mm,it allows up to 497.1 lx of average illumination,and the evenness can reach up to about 0.9.In the rapid development of LED lighting products,this kind of high uniformity and low glare LED eye protection table lamp design scheme has wide and bright practical and applicative prospect.

A weak optical signal detection lens is designed by optical design software – ZEMAX.The optical system requires small distortion and large relative aperture,which can match with the near-infrared CCD image sensor,in order to realize real-time,fast,high-precision detection of the weak singlet oxygen signal.The optical system parameters are relative aperture 1∶0.86,semi-image high 6.3 mm,spectral range(1 250~1 290 nm),magnification 1X,distortion0.1%,and manual focus.On the other hand,the mechanical structure of the optical system is design using the software-Auto CAD.The symmetrical structure is used to reduce costs and independent filter switching mechanism to facilitate the adjustment of the experiment.The detected lens successfully collects better weak singlet oxygen signals in the research experiments.
