Title:
REFLECTION-FREE LIGHT INTERCEPTION METHOD FOR ELIMINATING GLARE FROM LOW-LAMP-POSITION STREET LAMP, AND LAMP
Document Type and Number:
WIPO Patent Application WO/2019/153291
Kind Code:
A1
Abstract:
Disclosed are a reflection-free light interception method for eliminating the glare from a low-lamp-position street lamp, and a lamp. A light-intercepting plate of a pre-set length is arranged above the low-lamp-position street lamp at a pre-set angle to prevent a driver's eyes from directly looking at a light-emitting face of the low-lamp-position street lamp, so that direct glare from the low-lamp-position street lamp is eliminated. Moreover, all reflectors below the low-lamp-position street lamp are omitted, so that indirect glare generated by reflection by the reflectors is avoided. The glare-free low-lamp-position street lamp which is produced using the present method comprises a forward illumination light source (11), a reverse illumination source (12), and a lamp shell (13) without a reflector in the middle. The forward illumination light source (11) is located at an upper portion of the lamp shell (13), one side of a lower portion of the lamp shell (13) is of an inverted-V-shaped groove structure, and the reverse illumination light source (12) is located on the other side of the lower portion of the lamp shell (13), so that the inverted-V-shaped groove achieves the effect of a light-intercepting plate of the reverse illumination light source, and glare can be effectively eliminated.
