What is a led ring light?

1, led ring light tube

led ring lamp overall is a circular structure, round lamp ends respectively have a light-emitting filament, the inner wall of the lamp is coated with phosphor.

After the power is turned on, a trace of argon ,and thin mercury vapor inside the lamp will produce a conductive effect to emit ultraviolet light,

so that the phosphor produces a light-emitting phenomenon.

Led lights have many advantages, in energy-saving lighting, environmental protection and durable features are very prominent,

this led ring light tube is also used in some office buildings, shopping malls, factories, or home lighting.

2, led ring light how to install

Did home lead ring light failure, how to remove, replace, install it? The following is a brief description of the led ring light disassembly and installation steps for reference;

(1) single ballast wiring without distinction, that is, you can casually connect the zero line and fire line (fire line for white/red, zero lines for black)

(2) double ballast wiring is generally brown wire connected to the firewire, blue wire connected to the zero wire, the remaining two lines for the ground, direct ground wire on.
