| titleOfInvention | Optical module structure of pattern projection lamp |
| abstract | The embodiment of the invention relates to an optical module structure of a pattern projection lamp for automobile illumination, in particular to a multichannel optical projection module which is used for an automobile door welcome lamp and is used for projecting an artistic pattern with a special shape or a structured light pattern for creating a welcome atmosphere. The pattern projection lamp optical module is characterized in that: the multi-channel optical projection module adopts a fly-eye lens (lens array), and comprises a free-form surface collimation system with a large numerical aperture, a front fly-eye lens, a pattern film and a rear fly-eye lens. The multi-channel optical module at least comprises more than two optical channels, each optical channel projects the same pattern, and the clear and single patterns are formed after the optical channels are overlapped at a distance. |
