Title:
LIGHT-FOCUSING LED ILLUMINATION LAMP
Document Type and Number:
WIPO Patent Application WO/2019/170091
Kind Code:
A1
Abstract:
A light-focusing LED illumination lamp, comprising circuit boards (1) and several LED chips (2). The circuit boards (1) converge on one central axis, the LED chips (2) are provided at or near the central axis of the circuit boards, and an LED chip mounting surface (3) of one circuit board (1) near the central axis is provided at a position across an opposite surface (4) of an LED chip mounting surface of another circuit board (1) near the central axis in a direction towards an opposite surface of the LED chip mounting surface (3). The LED chips (2) are located at or near the central axis to yield a light focusing effect, thereby extending an illumination distance, achieving high illumination brightness and 360-degree uniform light emitting, and thus solving the problem of a poor pavement illumination effect of a vehicle.
