This 4.7W LED driver has been a few years old, and the design is not reasonable --- the power supply is large (easy to bomb), the output capacitor is easy to get pregnant, let's take a look at it.
LED street lights achieve ultra brightness/luminance; energy-saving over 70%. Special modular design for theLens (independent modules) and high luminous efficacy, high CRI, easy for maintenance.Intelligent and isolated power supply (NS semiconductor and Japan Rubycon capacitor), reliable and stable; automatically reduce current against overheating working temperature
