Description

L ED underground lamp with anti-dazzle function

Technical Field

The invention relates to the technical field of L ED underground lamps, in particular to a L ED underground lamp with an anti-dazzle function.

Background

L ED underground lamp is a novel underground decorative lamp which takes L ED with ultra-high brightness as light source and L ED constant current drive as driving mode, and is widely used for outdoor illumination of square, outdoor park, leisure place and the like, and adds luster for life.

Because L ED buries the lamp illumination time and is upwards setting, and bury the illuminating effect of lamp in order to guarantee L ED, and then L ED buries the light that the lamp sent comparatively strongly, when people bury the walking of lamp top in L ED, bury the light that the lamp sent and lead to the fact strong illumination to people's eyes, and then make people can appear transient blind phenomenon, when outdoor pedestrian is more, the easy collision that takes place, cause the emergence of incident, and strong light also can cause certain damage to pedestrian's eyesight, be unfavorable for viewing and admiring effect.

To this end, we propose an L ED underground lamp with anti-glare function.
