摘要
An embodiment of the present invention relates to a pattern design of a diffractive optical element for preventing a traffic accident during a bicycle ride at night time. According to the present invention, a grid pattern is widely distributed on the ground where a bicycle runs to brighten a dark road with illumination, thereby enabling a rider to easily secure a clear view. The grid pattern distorts according to a state of the ground such as a road bump, a cliff, etc. to enable the rider to estimate and recognize the ground and easily cope with an abrupt accident. The rider is able to look squarely on the pattern which freely deforms according to the ground while riding the bicycle, and thus the concentration can be improved and drowsiness while riding can be prevented. A user of the present invention can make other riders, riding on the road, recognize the user himself or herself, thereby preventing minor accidents.;COPYRIGHT KIPO 2019
