The Japanese manufacturer of auto components PIAA announced the start of sales of a headlight and flashlight heating system: the device looks like a transparent circle that is glued to the surface of a headlight or lamp and heats up to 60 degrees Celsius. The developer points out that this system is primarily intended for LED optics, which by themselves do not heat up enough to melt adhered snow or ice crust.
For the first time, the development of the PIAA was reported a year ago, but now the device has gone on free sale and costs from 16 thousand yen (about 140 dollars). By the time it was launched on the market, the technology had been finalized: initially the film was heated only to 50 degrees Celsius, but then the temperature was increased to 60 degrees. In addition, it is now possible to connect the device to the on-board 24-volt power system, which is often found on trucks and hybrids.
The transparent ring automatically starts heating up when the ambient temperature drops below five degrees Celsius. The heater can be powered from the ignition wire or from any other compatible source, including the “turn signal” power supply. Power consumption is about 5W per side.
Similar devices are offered by other companies as well. For example, the Finnish company Canatu produces a transparent film made from a polymer material that is resistant to temperature changes, which is equipped with compact heating points.
Japanese company Denso already sells a film heater, and this is an option for a number of Toyota models on the local market. It costs more – 25 thousand yen, or $ 220.
