Title:
HIGH-EFFICIENCY CONSTANT-ILLUMINATION STREET LAMP
Document Type and Number:
WIPO Patent Application WO/2019/015142
Kind Code:
A1
Abstract:
A high-efficiency constant-illumination street lamp comprises a lamp cover (1) and LED beads (2). An aluminum substrate (3) is arranged in an inner cavity of the lamp cover (1). Multiple LED beads (2) are fixed to the aluminum substrate (3). A supporting rod (4) is fixedly connected at one side of the lamp cover (1). A control board (5) is arranged in the inner cavity of the lamp cover (1). A CPU controller (6), a surging-prevention module (7), a dimming drive module (8) and an electricity leakage prevention module(9) are arranged on the control board (5). The CPU controller (6) is connected to the surging-prevention module (7), the dimming drive module (8) and the electricity leakage prevention module (9) respectively, and the dimming drive module (8) is electrically connected to the LED beads (2). The high-efficiency constant-illumination street lamp has a simple structure and principle and can continuously adjust the color temperature and power of the LED beads (2), thereby saving electrical energy to the maximum extent, and providing the surging and electricity leakage protection functions to protect the LED beads (2).
