Smart WiFi Single Line Switch Solution
Single Line Switch is the most important component of smart switch such as touch switch, wireless control switch, Zigbee switch etc, and its core technology is acquisition technology.
Technical difficulties:
A single line switch must flow through the lamp to obtain electricity, so when the power consumption of the switch is more than 220V / 50uA, the electricity reaches the capacitor charge, an instantaneous current is formed. A low-power W-number lamp, such as a 2W LED, is bound to flicker.
Because of the 2W lamp, the current it illuminates is very small, which is 2W / 220V = 9mA.
This is commonly known as "ghost fire", which is the flashing phenomenon of the lamp when it is turned off
The remotely controlled smart switch of wireless remote control requires more power and balances the "ghost fire" problem. This is the difficulty of obtaining power from a single fire wire. The instantaneous current required for the switch to work must be at least 2mA (315MHz) or 30mA (ZigBee).
For ZigBee switch products with large current requirements, it is more difficult to obtain power from a single fire wire.
In order to obtain the ideal single-fire
wire power solution, after years of basic research and technical research.
Transmei has launched a solution that links an adapter near the appliance so that smart wifi switch can be used normally.
