Abstract: An optical apparatus includes a structured light generation unit, a conversion lens module, a collimating lens and a casing. The structured light generation unit outputs a structured light. The light beams from the structured light generation unit are expanded by the conversion lens module. The expanded light beams are collimated by the collimating lens. After the light beams pass through the conversion lens module and the collimating lens, the light beams are projected to a projection surface. Consequently, a structured light pattern is formed on the projection surface. All conversion lenses of the conversion lens module have negative optical power. Consequently, the area of the structured light pattern on the projection surface is wider. Moreover, the structured light generation unit and the conversion lens module can be accommodated within the casing having a smaller thickness.

Abstract: An asymmetrical optical assembly employs reflecting surfaces and a lens to combine the light from a plurality of LED lamps into an illumination pattern useful in a floodlight or work light. The reflecting surfaces and lens optical element are not symmetrical with respect to a plane bisecting the optical assembly and including the optical axes of the LED light sources. Some light from the LED light sources is redirected from its emitted trajectory into the desired illumination pattern, while a significant portion of the light from the LED light sources is permitted to exit the optical assembly without redirection. Minimizing the number of optical elements employed and the redirection of light enhances the efficiency of the resulting light assembly.
