'Infraphil' was a clipping of Infrared and Philips
In September 1945 Royal Philips Electronics at
Eindhoven, The Netherlands, registered the brand
name Infraphil for an infrared incandescent light
bulb for medical and domestic heat lamp applications
and a specially designed suitable armature.
'Infraphil' was a clipping of Infrared and Philips, as
was common for many Philips products.
Infraphil incandescent heat lamps were designed for
medical applications and pain relief and differed
from infrared lamps for paint curing or other
applications. Infraphil heat lamps were dimensioned
for a maximum yield of short waved infrared
radiation that penetrated relatively deep into the
human skin.
