Title:
LED STREET LAMP PROVIDED WITH CONTROL CIRCUIT USED IN COOPERATION WITH PHOTOSENSITIVE RESISTOR
Document Type and Number:
WIPO Patent Application WO/2017/092023
Kind Code:
A1
Abstract:
An LED street lamp provided with a control circuit used in cooperation with a photosensitive resistor. The LED street lamp comprises a mounting substrate (32), wherein a PCB aluminium substrate (35) is arranged thereon, several groups of LED modules (36) are arranged on the aluminium substrate (35), a group of control circuits (37) and a group of photosensitive resistors (38) are also arranged on the aluminium substrate (35), and the other side of the mounting substrate (32) is provided with a layer of heat-conducting silicone grease gaskets (33) and heat dissipation fins (34). The arrangement of heat-conducting silicone grease gaskets and wave-shaped heat dissipation fins enables the heat dissipation effect to be significantly increased, and greatly improves the service life of an LED street lamp.
