More than wireless power transfer technology
Wireless bulbs in general, and WRLs in particular can be framed within the group of so-called "LED bulbs", but have a higher energy efficiency compared to them. This is due to the absence of the most important electronic circuit inside an LED bulb: the "Driver".
The "Driver" is responsible for adapting the external supply voltage, either AC or DC, to the voltage ranges suitable for the LEDs that the bulb incorporates. Curiously, this driver consumes a significant percentage of the total energy consumed by the bulb. And what is worse, its malfunction is the cause of most faults of an LED bulb.
The non-existence of a "Driver" in a WRL makes its energy efficiency increase, and its estimated average life is much higher than that of a conventional LED bulb.
The working frequency of a WRL is constant, and its value is in a range between 4KHz and 100KHz. These values are contrasted with the environment and, together with their reduced consumption, open up a very promising future in terms of their massive implementation.
But in addition, its contribution to the preservation of ecosystems derives from the absence of batteries among its components.
The WRL relies on multiple battery-powered signaling systems, such as zebra crossing floor lights or roadside signage systems, among many others.
