Summary |
The technology provides a collimating lens design method with freeform surfaces and an integrally-formed freeform collimating lens structure, thereby to save the required space and time for lens assembly, and the efficiency of collimation can be further improved for an LED light source. |
Industrial Applicability |
The technology can be applied to a collimated projection light source required for projection lighting fixtures, projection systems or detection systems, such as flashlights, searchlights, night vision systems or night vision photography. |
