[0015] Furthermore, in Japanese Patent No. 3685516 Figure 8 In the flash device described, the reflected light reflected from the reflector to the right front side at a relatively large angle to the main optical axis of the flash device to the extent that it does not hit the right side wall of the light guide lens may be on the right side of the light guide lens. The exit (illumination) surface is totally reflected, and does not irradiate in the direction of illumination of the flash device (within the viewing angle)

Abstract

The invention provides a flash unit capable of increasing light irradiating in irradiation direction (in visual angle) of the flash unit. The flash unit includes: a tubular light source (1) extending in left and right directions; a reflection mirror (2) for reflecting light from a light source (1); a light guiding lens (3) for guiding direct light radiated from the light source (1) and / or light reflected by the reflection mirror (2) after being discharged from the light source (1), wherein the light guiding lens (3) is composed by dividing into a plurality of lens sections (3a-3i) arranged on left and right directions, walls (3a2-3i2) on right side extending to right side and extending forwards relative to a main light axis (L) of the flash unit, and walls (3a1-3i1) on left side extending to left side and extending forwards relative to a main axis (L) of the flash unit are arranged on the lens sections.

Description

technical field [0001] The present invention relates to a flash device having: a tubular light source extending in left and right directions; a reflection mirror for reflecting light emitted from the light source; and a light guide lens which guides direct light emitted from the light source and / or Or reflected light emitted from a light source and reflected by a reflector, particularly relates to a flash device capable of increasing the amount of light irradiated in the irradiation direction (within the viewing angle) of the flash device. [0002] In detail, the present invention relates to a flash device capable of reducing light including light that can be refracted on an exit (irradiation) surface of a light guide lens and directed in a direction (angle of view) that deviates from the irradiation direction of the flash device. outside) irradiated light, or light that is totally reflected by the exit (irradiation) surface of the light guide lens and does not irradiate to th...
