摘要： A lamp module comprises a light source, a main reflector and an elliptical sub-reflector. The light source has a first arc and a second arc. The distance between the first arc and the second arc is an initial arc gap, and the light source is used for generating a light beam. The main reflector is used for reflecting the light beam and has a central axis, and the light source is disposed on the central axis. The elliptical sub-reflector is used for reflecting the light beam to the main reflector. The elliptical sub-reflector has a first focus and a second focus, a center of the light source is positioned on a long axis of the elliptical sub-reflector and between the first focus and the second focus, and a distance between the first focus and the second focus is larger than the initial arc gap.

摘要： High performance lens system designs are described. The lens system has four lens groups, is made entirely of spherical lens elements, and, includes selected lens elements made of materials with high refractive index and Abbe numbers and coefficient of thermal expansion that provide stable high performance across wide and rapid temperature changes. Group descriptions and parametric equations enable creation of designs having fields of view ranging from 50 to 150 degrees.

摘要： A light source module includes a light source, a paraboloid reflector and an aspheric lens. The light source is used for generating a first light. The paraboloid reflector is used for reflecting the first light beam to form a second light. The aspheric lens is used for converging the second light. The aspheric lens includes an aspheric incident surface and an emergent surface. The aspheric incident surface is used for converging the second light beam into a third light, and the emergent surface is used for converging the third light. The emergent surface includes two aspheric curved surfaces configured symmetric to an optical axis of the aspheric lens.
