Led Lighting Device, Street Light, and Optical System for Led Lighting Device

摘要: A reflector has a reflection plane for reflecting light emitted from an LED source in the direction that goes away optical axis of with respect to parallel axis, whereby effective use can be ensured by reflecting, example, peripheral light, which normally cannot effectively used, proper and causing reflected enter diffusion lens. Further, using abovementioned plane, thickness reduced effect increased, thereby enabling increase flexibility design lens reduction thereof, consequently lighting device reduced.
