Title:
LIGHT-EMITTING FLASH LENS, AND LENS UNIT
Document Type and Number:
WIPO Patent Application WO/2010/067935
Kind Code:
A1
Abstract:
The present invention relates to a light-emitting flash lens which is used as an assistant light source for a camera, and which comprises a refraction unit for controlling light emitted from the front surface of a light-emitting body to maximize light efficiency, and to a total reflection unit for controlling light emitted from the side surface of the light-emitting body. The lens of the present invention is formed into a square shape to utilize light emitted from LEDs in all directions. Thus, light emitted from LEDs is illuminated into a square shape to match the area captured by the camera, thereby maximizing the efficiency of illuminating light.
