Philips Infraphil KL7500 heat lamp
the 2008 Philips word mark update
During the introduction of the first Philips
Infraphil heat lamp, de Philips word mark
consisted of the name 'Philips' in uniform
capital letters and in a sans-serif font.
This word mark was initially printed on the
heat lamps, in the user manuals and on
the packaging of the armature. It was
only in 1960 with the introduction of the
Philips Infraphil KL7500 that the Philips
word mark was used on the armatures as
The Philips word mark was modernised in 2008. The characters became a little
thicker and somewhat closer together, there came a difference in thickness between
the horizontal and the vertical lines, the P’s and the S became more round and open,
the L became skewed at the lower right
end and a deeper tint of blue was used.
The renewal of the Philips word mark
coincided with the end of the commercial
exposure of the Infraphil brand name.
Infraphil heat lamps that were produced
since 2008 carried the new Philips word
mark but no longer the brand name Infraphil.
